What's up, son? It's Blindruck with Sound Attack. Once again, and today I have yet another mining video for you. Today we're going to be taking a look at none other than the brand new graphics card from Radeon, the RX 6800, and its mining performance in Ethereum. Now for this channel in particular, we do cover gaming as well as mining on all of these graphics cards. So if you are interested in the gaming portion, come back later. And to make sure you get that video, hit the sub and the notification that will be coming later this week. But a real quick note on this GPU, all of these initial tests are with unoptimized minors and no bios modding available currently. So if you're interested in those as well for the mining portion, make sure you hit that sub and that notification because we'll be covering it when we have access to those tools. Without further ado, let's talk about mining Ethereum on the RX 6800. 5 feet of bears. Start things off. Let's go over the test bench. We will have links to all the parts down in the description below. We're running an ASRock Tai Chi B550 motherboard with 16 gigs of Trident Z Neo clocked at 3600 megahertz and with your timings at 18kaz latency. That being said, we also have the brand new AMD Ryzen 5600X Ryzen 5 and we'll be having a separate review for that coming out as well. So once again, make sure you hit that sub and notification if you're interested in awesome new stuff coming to the channel, awesome new parts coming out from all of our favorite technology companies and it couldn't be a better time of the year. I hope you get your hands on it. Just one of the parts that you have on your wish list for Christmas and let's talk about mining Ethereum. So the big notes about mining Ethereum is that we are looking at return on investment, meaning that the metrics that we're trying to figure out at the end of the day is which GPU has the best ROI or return on investment and then that's how you would determine which GPU you should buy. Alive this will come down to if you can get the cards at retail cost and so on and so forth. So in the current market, you're probably still going to be better off getting the RX 5700 or 5700XT just based on availability. But once these RX 6800 become available at retail, is it worth purchasing them over the 5700 series? Well let's talk first a little bit about what's changed with the new models. The RX 6800 is a 7nm GPU with RDNA2 architecture. The boost clock is up to 215MHz with the game clock of up to 1815MHz. Now it has 16GB and this is the important part of course when we start talking about mining has 16GB of GDDR6. This will be important because basically you're never going to have to worry about the DAG for years which is awesome. The current DAG is going to be kicking some 4GB cards off ETC which is Ethereum Classic is going to be making some modifications to fix that and allow you to mine with 4GB cards on them. And a miner called LOL miner is currently working on a miner to still support 4GB cards on the regular or you know the Ethereum blockchain. But that is all speculative at this time so having more memories probably just going to make everything that much easier for you if you're trying to mine Ethereum. Now the memory clock is 16GB per second effective. You do have a maximum of 4 displays of course for mining we're not that worried about it but you do have 2 display ports, 1 HDMI and a USB-C. I love seeing the USB-C on there. That is amazing. This PCIe expressed 4.0 for mining this shouldn't be that big of a deal either. You can knock down that PCI, Gen, depending on you know your mining rig and so on and so forth. This particular card is the reference model but it was built by a third party vendor which is Sapphire. I think that's important to note because there was a big hubbub about not allowing third party AIBs to launch on the same day as the reference models. That doesn't mean that the third party AIBs didn't actually get a chance to make cards. It's a little different than Nvidia. As Nvidia when they have their reference models that is for Nvidia only like Nvidia doesn't share their reference model designs out with their board partners to manufacture additional reference cards. As opposed to AMD who shares out their reference designs with their third party vendors so that they can build more reference cards or at least in theory. Now what they are limiting is the ability for them to come out with custom coolers until the 25th. The good news for you guys and I'll leave a link with the Amazon link down below is you will have another chance to buy these custom cooled versions on the 25th or in 4 days from this video. Pretty awesome. Now the reference model design is going to be a three fan design. It does include a backplate. We already talked about the outputs and you do have two eight pin power adapters required with no funky adapters needed in this particular case. When we're talking about minimum power supply for a system it says 650 watts. That's going to be a little bit different obviously with mining and we'll talk about all of that right now. So on Ethereum right off the bat we hit around 58 to 59 mega hash a second. That was without any modifications to the card whatsoever and that was at 175 watts. Now there's a new feature that is in the overclocking tab of the radion software. If you go into the radion software what you'll notice is that there's an option to select fast timing. If you're going to be mining on windows go ahead and do this now. What fast timing is going to net you is another couple mega hash a second solidly getting you from the 58 mega hash to 59 mega hash to 60 to 61 mega hash just with that setting. Once you've done that you want to start going in and taking a look or we wanted to go take a look at overclocking memory. Now with overclocking memory it does perform very well but it does perform very similar to other GDDR6 cards so it's pretty predictable. Meaning that all you really need to do is take it and slide it up to about 2100 megahertz which is where we found the absolute limits on this particular card and that netted us another couple mega hash a second taking us from 60 to 61 mega hash a second to 62 to 63 mega hash a second. We were pretty happy with those results and we knew that we basically now just need to work on power consumption so our power consumption was still around 175 watts. What we ended up doing is downclocking the core as far as we could. Super impressive that you can actually downclock the core on this particular GPU in this 6800 all the way down to about 1150 megahertz. Meaning that you will be able to undervolt the core all the way with whatever is available in the radion software and hopefully once we get Linux drivers and high OS and all of that kind of figured out and ironed out we should be able to get that core clock lower than any other AMD GPU in the past because basically on the RX 5700 for example going below around 15 or 1400 megahertz on the core starts hurting your hash rate going to 13 to 1300 megahertz will definitely take your hash rate on the 5700 so knowing that we can get the core clock down an additional 150 megahertz over the 5700 XT on this 6800 tells me that we're going to be able to undervolt this beyond the 740 to 750 millivolt range which should get us under 100 watts but the only thing I can verify for you guys at this time is that the RX 6800 with overclocking and fast timing enabled as well as underclocking on the GPU core and undervolting which the lowest it'll let us take the core voltage down to is 793 millivolts is going to be 63 mega hash at 125 watts now if we go ahead and plug this into what to mine your numbers will vary depending on you know how much eth is worth and it's going up along with how much your power costs and so on what I can tell you is that based on revenue currently and compared to any other GPU it has the fastest ROI time at this time of 8.8 months versus the next best bet that I have at the moment which is the RX 5700 at $350 coming in at around a ROI of 10 months so we have a faster ROI even without getting the power consumption low like lower or as low as that I think that will presumably be able to get it I'm going to be super excited to mess with BIOS power play settings and etc to get you guys the absolute best RX 6800 overclock and BIOS mounting settings for mining Ethereum but at this time this is what we have you're going to basically go into your radion settings you're going to undervolt your core clock to or your core voltage to 793 you're going to underclock the core clock down to 1150 you're going to try to get to 21 megahertz on your memory and enable fast timing and that will be the best settings for you at this time I hope this video was helpful and informative and I hope to see you next Tuesday Adios
