[Samsung Galaxy S21 Ultra] ssj100:
No, Korea used snapdragon for S20 series but exynos for S21. The video I linked is a person recording in South Korea and he confirms he uses exynos.

As for at least one of those reviewers that I linked just before, they actually posted an updated video following the flurry of updates for the exynos version in late February. So it's possible he could do another update. But yes, it's a shame people don't do comparisons following these software updates. I actually think it would be ideal to do direct comparisons 2-3 months following release for these Samsung flagships, just to more objectively confirm that Samsung does fix/improve things with time.
[Samsung Galaxy S21 Ultra] aj7400:
Okay let me correct you ,

Korea is using exynos this time around .
[Samsung Galaxy S21 Ultra] ekerbuddyeker:
to me, looking at the youtube results, it generally looks like the Ultra Exynos 2100 is faster than the Note 20 Ultra Snapdragon, with 8.5 hours SOT, while Snapdragon 888 is faster still and 9 hours SOT. not much in it, it seems, but still the Snapdragon looks superior, just less of a gap than was on S20 and Note 20 Ultra.
[Samsung Galaxy S21 Ultra] -Zork-:
Almost all review of snapdragon 888 is from xiaomi 11, are there any of s21 ultra snapdragon?
[Samsung Galaxy S21 Ultra] hellfire8888:
S21 ultra cpu performance is bad with exynos 2100 the battery life is poor , telco reception is bad and have overheating issue
[Samsung Galaxy S21 Ultra] Frostfree:
Where's this from? The CPU in the Exynos 2100 and Snapdragon are exactly the same except that the Exynos's Cortex-X1 core is clocked slightly higher than the Snapdragon's - so slightly faster. The GPU is where the Snapdragon is superior, however it looks like the Exynos may have slightly better battery life.

[Samsung Galaxy S21 Ultra] hellfire8888:
I have the phone in my hand , all the benchmark result show it is performing worst than snapdragon 865
[Samsung Galaxy S21 Ultra] mikey_sk:
you must have a bad unit as mine is fine and, never overheats and has great battery life
[Samsung Galaxy S21 Ultra] hellfire8888:
i guess you must have a good unit. can you share your geekbench and antutu benchmark result here?
[Samsung Galaxy S21 Ultra] piyush7243:
Mine geekbench on Exynos version is

943 and 3036

Antutu is around 615000
[Samsung Galaxy S21 Ultra] UNIK97122:
strange result, you are in battery save mode ????? even my s20 ultra is better.....

[Samsung Galaxy S21 Ultra] pafc66:
Seems like the exynos over sharpens photos hard compared to the snapdragon from what I've seen.
[Samsung Galaxy S21 Ultra] piyush7243:
No idea about Snapdragon but Exynos pictures are definitely oversharpened and lot of digital noise
[Samsung Galaxy S21 Ultra] pafc66:
I've seen samples from both devices and the exynos over processing is ridiculous. They better fix that up. Reminds me of what the snapdragon version used to do on the s20 series actually.
[Samsung Galaxy S21 Ultra] UNIK97122:
i just test , my S20 ulra pictures look's better o_O
[Samsung Galaxy S21 Ultra] mishufac:
For sure your unit is bad. Even in Power saving I don't get that bad result
[Samsung Galaxy S21 Ultra] piyush7243:
My unit have same single core scores but multi cores is 3000-3100
[Samsung Galaxy S21 Ultra] m00trix:
All good here. Exynos 2100. Super nice performance
[Samsung Galaxy S21 Ultra] merewood bebox:
GPS on exynos is worse, highest accuracy us 6m compared to 3m in direct skyline, i can get 5m indoors with oppo find x2 pro, but i cant get less than 12 m on 21 ultra exynos

Did you calibrate the compass? You do that through Google Maps, locate yourself, when you see the round circle that shows around your location, hit the calibrate compass.. You have to do the number 8 gesture to make sure everything will be OK.

Apparently my ultra is between a pixel 4 and iphone 11. Sweet. Well worth the $million.
[Samsung Galaxy S21 Ultra] cheetah2k:
888 and 2100 core structure are the same, except the 888 has custom Kryo cores vs the standard ARM design of 2100. So... Technically speaking, not same same
[Samsung Galaxy S21 Ultra] lywyn:
UK Exynos version, just tried Google Maps and says accuracy high (8m). I checked accuracy by measuring the area marked on maps vs real-world measurements as was actually around 6-7m. The centre dot was on the house and centred exactly side of my kitchen I was in so I'd say it was accurate to 1-2m

Great news for Exynos variant owners (which I am one). Better battery and less heat. I'm sure the SD will be better for gamers but I'm not a mobile gamer so happy with what I the chip.
[Samsung Galaxy S21 Ultra] Neo_Sk8eR:
Seem neck and neck when it comes to battery at least
[Samsung Galaxy S21 Ultra] UNIK97122:
yes, but i now need a pictures test between both ...
[Samsung Galaxy S21 Ultra] dscline:
I'm not sure what you would gain from that. As far as I know, the camera hardware is the same between the two. Any differences would likely be due to firmware, so any comparison could be obsolete at the next firmware update.
[Samsung Galaxy S21 Ultra] UNIK97122:
it's look the exynos versions is worst than snap rigt now, and my s20 ultra produce better pictures actually
[Samsung Galaxy S21 Ultra] piyush7243:
Battery life has been really good on my Exynos 2100.
[Samsung Galaxy S21 Ultra] nightoooo:
To make things shorter, if you are not a top gamer, the Exynos 2100 is just great for you!

If you are a top gamer that wants the best graphic experience, go for the Snapdragon!!

The Exynos 2100 is very good, especially in battery life and row performance.
[Samsung Galaxy S21 Ultra] UNIK97122:
but if you're real gamer you won't play on smart phone, pc only :cool:
[Samsung Galaxy S21 Ultra] ssj100:
From most of the reviews and "expert" comments so far, in everyday real-life usage, both Snapdragon and Exynos are pretty similar. If anything, Exynos may actually be slightly better in terms of battery life and not "over-heating". The only clear advantage of Snapdragon is with (prolonged) gaming, but that doesn't mean you can't enjoy reasonably good quality gaming with the Exynos.

The only confusing aspect for me is the Camera. There appears to be quite large discrepancy in the reviews of this. Initially, most (all?) reviews basically implied it's good to excellent (Exynos). But then a thread appears on these forums with multiple posts commenting on how bad it is. Then a YouTube video comes out also essentially reporting that it's pretty bad:

My question ultimately is whether the Snapdragon camera system would be any different to the Exynos?
[Samsung Galaxy S21 Ultra] nightoooo:
Or PS/Xbox..
[Samsung Galaxy S21 Ultra] nightoooo:
Regarding your concern ... Samsung always make their cameras better with SW updates.

Regarding your question, i think the access to ISP in both Exynos and Snapdragon is the same!! Before in time with older Exynos that was one of the most bad things, now it should be solved.
[Samsung Galaxy S21 Ultra] Virgo_Guy:
Arun @ Mrwhosetheboss came up with this excellent comparison, clicking all the right boxes. Snapdragon version is overall the better one.
[Samsung Galaxy S21 Ultra] Batfink33:
His temperature comparisons are spurious. My Exynos idles at around 32deg C. I think he's right about camera though.
[Samsung Galaxy S21 Ultra] lawtq:
Concerning battery life, its back and forth between the exynos and the snapdragon, its negligible.
[Samsung Galaxy S21 Ultra] Virgo_Guy:
I would say that would be a strong word to use against someone who has both the versions, and then went in-depth to compare. 😊

To each his own, I could thoroughly agree to the points he made.
[Samsung Galaxy S21 Ultra] Batfink33:
I was just using a temp app to monitor temp with Exynos and it said it was idling at 32. Antutu does say its idling at 42degC so he's correct. Which app is giving me the right temperature I don't know.
[Samsung Galaxy S21 Ultra] lawtq:
Snapdragon is still the best buy. Camera and gpu especially
[Samsung Galaxy S21 Ultra] Batfink33:
Just double checked the temperature issue and Antutu doesn't read the Exynos temp correctly. A simple Google and read of previous Exy Antutu threads will give the explanation of this. I used CPU monitor (which does)and it idles at around 32degC and feeling the phone,this "feels" more correct. I do however agree SD is better for GPU. Another thing you can see on that comparison video is that on the phone with the Snapdragon, scene optimiser is on on the SD whereas its off on the Exynos camera. This would make the SD cam look better.
[Samsung Galaxy S21 Ultra] ssj100:
Apparently the scene optimiser was confirmed/clarified disabled on both in actual testing.

For me, having never installed a game on a smartphone, I'm not worried about prolonged gaming performance. However, it is disheartening that the camera appears consistently a little worse on the Exynos.
[Samsung Galaxy S21 Ultra] Batfink33:
Yes, it's very annoying that Samsung sell poorer performing phones outside of the US and there's no doubt the Exynos isn't as good as the SD. I'd just perhaps wait for more confirmation that the camera isn't as good. There's also a new Exy update today that's rolling out that has improved camera in its changelog.
[Samsung Galaxy S21 Ultra] lawtq:
I messaged mrwhostheboss and told him those wild antutu cpu temp measures were wrong

I've updated. Camera looks exactly the same to me, unfortunately
[Samsung Galaxy S21 Ultra] Batfink33:
Not good
[Samsung Galaxy S21 Ultra] Mini Jay:
For the camera just edit the photos in lightroom the way you want and you'll get the perfection image for you instead do relying on any manufacturer AI
[Samsung Galaxy S21 Ultra] dazed1:
Can you post some night mode samples?
[Samsung Galaxy S21 Ultra] EbolaCola:
Problem is, in the US we're stuck with perma-locked bootloaders & no root. I'd happily take an Exynos S21 over Snapdragon if I could root it.
[Samsung Galaxy S21 Ultra] Mini Jay:
Hello I'm kind of new with that root thing that i keep reading everywhere... But what is the benefit of rooting our phone with (concrete example if possible)
[Samsung Galaxy S21 Ultra] Allesa:
I Respect the guy, and love his videos.

However I dont think he should quote antutu temp monitor. I don't think Exynos gives access to its CPU temp. So the numbers for CPU temp given by Antutu may not be correct. To check, download AIDA64, CPUZ, and CPU float. All of them can’t access exynos’ CPU temp data (only battery temp), while on snapdragon chipsets they do give comprehensive access for cpu temp data. This happened also in mediatek Dimensity 1000 I tested last year. Antutu miraculously pull a number that other apps can’t provide. Another app that can “access” exynos cpu temp data is cpu monitor. Unsurprisingly when you look at the temperature data of exynos from those 2 apps (antutu temp monitor & cpu monitor) while running a benchmark, the numbers aren’t remotely close. Antutu gives 60c + temp while cpu monitor showing 30c+ temp--
[Samsung Galaxy S21 Ultra] Mini Jay:
I respect him a lot as well but this time I don't follow his video and thoughts. When he said that Samsung release an Exynos version and a Snapdragon version of the S21 Ultra, it feels like he just discovered that. Then when he sees there's major difference with the camera between Exynos and Snapdragon, What he showed on his videos aren't dramatically different. By the way some shot was better on Exynos some was better on Snapdragon. Yet he only mention when the shot goes wrong with Exynos. Biased. The PlayStation emulator scenario, again there were no dramatic difference (plus I'm not even sure if that example is valable. Run a Genshin impact at 60fps with Exynos and Snapdragon. What's the use of scenarios that doesn't even represent what the majority do or play with their phone.)

Finally he said that he doesn't believe that these "issues" can't be fixed by software update because the phone are already on the market?

Should we begin with the number of games that are released unfinished but get "finished" with updates ? Ok I digress.

So when Samsung release updates they can't make adjustments on their software ? Weird, we received an update on the S21 Ultra recently to improve the cameras.

The only part on the video where it made sense for me is the part when he charged the phones and run his tests and then talk about temperature and stuff.

I respect that guy a lot but, the bashing over Exynos i don't get it. Particularly when numbers of Exynos users seems satisfied with their s21Ultra, which wasn't the case in the past
[Samsung Galaxy S21 Ultra] Allesa:
Im a tech reviewer with merely 170k subs on youtube. Tested Iqoo 7 and mi 11 with sd 888 already, s21U sd888 coming next week.

My conclusion based on iqoo 7 and mi11 is that sd888 is a hot SOC especially when compared with 865 and + that runs relatively cool no matter what you do. That includes running ROG 3 X mode without any extra coolers which runs genshin impact 46-47c. Mi11 easily reach 51-52c battery temp (ambient temp 24 deg) while idling on genshin impact full settings. Even when using monster mode which basically its gaming mode, Iqoo throttles its SOC prowess at 45deg. While benchmarking both runs full speed and it gets to 51-55 degrees. On 3dmark wild life, Mi11 crash all the time due to overheating, while iqoo 7 managed to finish with whooping 58c final temp and stability of 93%.

On the other hand, exynos 2100 runs max 45c battery temp no matter what you do as it throttles down the performance at around that temp. This is similar to what other sd888 s21U tests circulating.

So seeing a claim that Exynos 2100 is hotter that Snapdragon 888 makes me wonder.

By the way, when testing iqoo 7 on wild life, holding a phone with 58 degrees temp is painful. It's WAY TOO HOT.
[Samsung Galaxy S21 Ultra] pafc66:
Ok got my hands on a snapdragon s21 ultra and compared with my exynos s21 ultra. The camera quality is almost light and day. The exynos oversharpens shockingly to make up for less detail it's inferior ISP can process so it tends to just up the sharpness in a attempt to compensate which looks over processed and just shocking. It's pretty bad when you pixel peep but even when you don't it's quite obvious especially in trees and fine detail ect.. Colours are better on the snapdragon as well. Updates might fix it but I doubt it. My note 20 ultra (snapdragon) took better photos than this exynos s21 ultra. It's laughable that these are the same phones. Disappointing as usual especially after they've made ground in battery and performance. I'll continue to import SD.
[Samsung Galaxy S21 Ultra] kyero985:
Here's a (less popular but still interesting nonetheless) YouTuber comparing the SD and Exynos in 4k low light video capture. It's definitely a big eye opener and I was shocked by the results. While he hasn't included any photo comparisons, I'm sure we can all get a general idea of what to expect anyway.
[Samsung Galaxy S21 Ultra] nightoooo:
I have seen many videos from this guy, he is doing good, now the difference between the two chips is very minimal, it's seems a tuning thingy rather than HW issue, i didn't like any of the phones in low light video, i think Samsung have to be better on this point because iphone still ahead in video.
[Samsung Galaxy S21 Ultra] Batfink33:
He like every other YouTuber has to pull in views and likes and look at the interest it's caused. Just by Googling Antutu and Exynos will tell you it doesn't read the Exynos temps correctly and just by holding the Exynos phone you can tell its not running at 40+degC. On one of the comparisons, he has scene optimiser on on the SD version but off on the Exynos version.At best he's just not done his research for the video but it just smells to me like he's trying to get views and likes. That's not saying that the SD version isn't better because it is but what he's trying to claim here is isn't correct.
[Samsung Galaxy S21 Ultra] Batfink33:
Can you post some comparison photos of the s21 Ultra Exy V SD?
[Samsung Galaxy S21 Ultra] lawtq:
We need to see! Please

Thanks
[Samsung Galaxy S21 Ultra] rexisrex:
Guys I have the Exynos Indian Variant. Did a latest stock firmware flash via odin. Always do with Sammy devices as they suck with ota when the Android version changes due to cache issues. ( Use fridja tool. Google it to get your stock firmware)

The phone is fast and battery life is awesome. Attaching my battery screenshot. Consistent 8.30hrs Plus SoT with almost 2 days of juice.

Not sure if YouTube reviewers are tad biased towards Qualcomm! , But I can honestly say 2100 is leaps in front of 990. Also I don't believe in running 10 times stress test and saying Exy lost it. Who in normal life is ever going to do such stress test with phone? I also did 2 hrs of Cod and battery dropped just 8% and phone was cool and I live in one of hottest city in india! So overall I'm impressed with the phone and I don't want Gary explaining my phone to me! 😊

[Samsung Galaxy S21 Ultra] oae08:
I really hope samsung gives yet another camera update and fixes the Exynos2100 problems as this is not acceptable quality for even a medium range phone
[Samsung Galaxy S21 Ultra] Mini Jay:
I don't want to alarm anyone but i own the s21Ultra Snapdragon 888 and the first time I used the camera i wasn't impressed. In my opinions the images are oversharped (zoom in every photos and it's hard to not see some mushy things going on. Let's say that in the Mobile phone realm it's not bad. Now I own a mirrorless camera so I may be too picky when it comes to image quality.)

So is Snapdragon better than Exynos? If it is i don't think it is by a huge margin. Now Exynos and Snapdragon process the image of the camera but it is Samsung's algorithm (their AI) who dictates how they want the photos or videos to be in terms of shadows iso color grading contrast sharpening etc. So I believe that the image quality (therefore AI) can be addressed with an update (if they ever agree that their AI can be improved). It's not so much of a hardware issue but the way they code their AI to interpret what they believe you be a good photos.

Now why the Snap and Exynos have different results at the moment they are launched in the market?

Because it's not the same processor, therefore having differences is quite frankly to be expected. But as you all know we will have software updates that will improve the camera performance (and other performance as well).

So what's the point of comparing precisely the S888 and Exynos and popping up some scientist conclusion at t-time when future updates will optimize these processors even more (or less?).

Yes, for the sake of likes and comments on YouTube. It works tho, I rarely comments, but well that S888 vs Exynos should stop. We needed to know how far they are different. The answer is they are pretty close. That's all matter.

Good battery life (and hell yeah that matter)

Good performance (and don't bring that playstation emulator situation up, because that scenario doesn't represent the usage of the majority and frankly the differences weren't even dramatic)

Comparable cameras (in my opinion, overall equally as good. Sometimes Exynos better, sometimes Snapdragon better. It's a draw)

[Samsung Galaxy S21 Ultra] oae08:
No it is really true, the exynos camera is worse than my 300$ honor phone!
[Samsung Galaxy S21 Ultra] Sukrith:
Actually Gary hasn't said anything bad about either SoCs! And I totally agree with you! The phone is amazing in its own right and I feel its the phone with no compromises like the other brands! The current camera and other "issues" can and will be fixed by Samsung this time as if they get bad press regarding an inferior exynos, they are screwed this time around for sure!
[Samsung Galaxy S21 Ultra] Sukrith:
It basically let's you change even the smallest aspect of your phone! Things rooting can help you with are,

Overclocking

Voltage control (with proper kernel)

System wide theming

Adding or removal of features and apps

Cracking apps

Complete data backup(titanium backup or custom recovery)

So on and so forth!
[Samsung Galaxy S21 Ultra] Mini Jay:
Thanks for the explanation! Tho I'm not sure I'm interested in any of the possibilities offer by rooting a phone but it's good to have options 😁

Another comparison (spoiler - they are very even in performance here, which seems quite different to many early reviews - Exynos updates helping perhaps?):

Exynos 2100 vs Snapdragon 888: Benchmarking the Samsung Galaxy S21 Ultra versions

We have some performance numbers of our own to go over and examine. For quite some time now Samsung has been releasing two versions of most of its premium...

www.gsmarena.com
[Samsung Galaxy S21 Ultra] Mini Jay:
Yes I read the article. Reviewers particularly Mrwhosetheboss's video comparing the two chipset has generated a lots of disagreement. In the past, stating that the gap between Exynos and Snap was huge could be acceptable and heard by the majority. But this year, Exynos users who freshly bought the s21 Ultra tend to disagree quite a lot with the reviewers who only seem to make videos to generate views.
[Samsung Galaxy S21 Ultra] lawtq:
It deffo has not improved the camera. Unfortunately
[Samsung Galaxy S21 Ultra] Sukrith:
It isn't worth it nowadays! I used to root my phones and do all crazy things during my Nexus days to add more features but nowadays Samsung and almost all the other OEMs have added so much of all those to the system, it really isn't worth the sacrifice of warranty for!
[Samsung Galaxy S21 Ultra] Mini Jay:
Oh I see ! Good to know because I thought I was missing something big 😅
[Samsung Galaxy S21 Ultra] ssj100:
A nice real-world straight-up comparison (I think Exynos overall slightly better with pictures, but slightly worse with video):

To be honest, I'm not convinced one is clearly overall better than the other. It'd be funny if a (reputable) YouTube reviewer did a demonstration of 2 identical phones (either 2 Exynos or 2 Snapdragons) but didn't disclose they were identical until a follow-up video. I wouldn't be surprised if people's biases made them pick one phone (assuming it was Snapdragon) when they are in fact both Exynos!
