[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
I will write in text as the S8 is busy benchmarking right now, and I will post this only after everything is done. I need a lot of time just to benchmark, so sending images would furtherly increase the amount of waiting.

Icestorm Unlimited: Invalid

CPU ran at 2652MHz and GPU at 839MHz. GPU test saw little to no improvement on GPU performance, except for GPU test 2, which did 196,7fps. CPU with a good score at 95,8fps. First test is 210fps. Invalid. Score is around 41,760, don't remember totally.

Note: Testing parameters for all following benchmarks change a bit to keep temps as low as possible. I will be running GFXBench later on if requested.

CPU: 2652 -> 2574.

Slingshot Unlimited:

Total: 4,907

GPU test 1: 37,2fps

GPU test 2: 19,9fps

GPU TOTAL: 5,977

NOTE: GPU throttled down to 764MHz at the end of GPU test 2. CPU tests got affected by the high temperature reached by the SoC and score suffered. Potentially, 5,000 is achievable. I trust that rtyuakatsuki can do it.

CPU test 1: 58,4fps

CPU test 2: 31,8fps

CPU test 3: 16,4fps

CPU TOTAL: 3,026

Thoughts:

In GPU test 1, we saw a 23% improvement over my highest score on previous Kernel versions with 572MHz as max GPU speed (30,2 -> 37,2)

In GPU test 2, we saw a 35% increase in performance over my highest score on previous Kernel versions with 572MHz as max GPU speed (14,8 -> 19,9)

CPU scores are irrelevant, as in the past I did get better performance due to the lower GPU speed, which in turn heated up the phone less and allowed CPU to have some headroom.

So in total, GPU score increased by 31% (4,576 -> 5,977)

Total score increased by 19% (4,131 -> 4,907) Could be moderately better with no throttling.

For the following tests, to get performance as stable as possible, the following changes will be applied:

GPU: 839 -> 764.

Slingshot Extreme Unlimited OpenGL ES 3.1:

Total: 3,859

GPU test 1: 31,6fps

GPU test 2: 12,7fps

GPU TOTAL: 4,174 (GPU did not throttle. These results are effective 764MHz).

CPU test 1: 58,1fps

CPU test 2: 31,9fps

CPU test 3: 16,7fps

CPU TOTAL: 3,052 (Irrelevant, throttled to 2GHz)

Thoughts:

In GPU test 1, we saw a 19-20% improvement over my previous highest score (26,6fps -> 31,6fps)

In GPU test 2, we saw a 30% improvement over my previous highest score.

In total, GPU score increased by 26% over previous figures (3,307 -> 4,174).

CPU scores are irrelevant as they throttled. Yes, there is definite potential to do 4,000, and rtyuakatsuki could achieve it with 839MHz GPU and 2652MHz (minimum) CPU.

Total score increased by 19%.

AnTuTu V7:

Note: GPU test 2 and 3 throttled, especially 3 due to the high intensity of 2. Scores could be better. Additionally an overlay accident might have impacted the GPU score slightly. CPU throttled. Score is affected.

Total: 244,608

CPU: 76,442

GPU: 107,220 (Perfectly on par with Mali G72 MP18 @572MHz despite the throttling).

UX: 50,202

MEM: 10,744

Thoughts: I can't provide figures for CPU, UX and MEM as they are all affected by throttling/higher CPU frequencies. But GPU saw a 16-17% increase over my previous highest scores (around 92,500 -> 107,220).

Testing is done. So let's get some comparisons down to get an idea of how close this got to an S9 (Again, rtyuakatsuki can achieve even higher scores, potentially beating/matching a stock S9. I can just provide baselines due to my limited cooling capacity. However I ordered a second cooler, to try and improve what I can do).

The average S9 scores about 3608 for Slingshot Extreme Unlimited OpenGL ES 3.1

With 2660 on CPU score (most likely throttled)

and 4,024 on GPU score (most likely throttled too)

GPU test 1: 28fps

GPU test 2: 13fps

CPU test 1: 46fps

CPU test 2: 27fps

CPU test 3: 16fps

So here it's a win for us, even if most likely a non throttled Note9 (Most powerful iteration of E9810) can win.

The average S9 scores about 4016 for Slingshot Unlimited

With 2599 for CPU score (Most likely throttled)

And 4791 for GPU score (Most likely throttled)

GPU test 1: 30fps

GPU test 2: 16fps

CPU test 1: 44fps

CPU test 2: 26fps

CPU test 3: 15fps

The average S9 scores around 250,000 on AnTuTu V7 (Android 9 scores, as Android 8 had older and underperforming GPU drivers).

CPU: 87,000-92,000

GPU: 103,000-107,500

UX: 53,000-56,000

MEM: 8,300-9,000

And with this, for today it's done. I can answer questions as long as they are reasonable.

Note: There IS a large range of scores that E9810 achieves. The peak figures from E9810 remain on top compared to the current Kernel release, but as I said before, rtyuakatsuki can nearly match or totally match the peak stock E9810 figures.
