AMD RX 6800 GPU Review vs. RTX 3070: Gaming, Ray Tracing, Thermals, & Smart Access Memory

Our review of the AMD RX 6800 video card compares it vs. the NVIDIA RTX 3070, where the 3070 struggles in rasterization, but pulls way ahead in ray tracing. SAM testing, power, & OC included. This review includes a lot of benchmarking. The complexity of adding Smart Access Memory (SAM), the variability of RTX or RT features like DLSS, and the differing behavior at 1080p, 1440p, and 4K means we had to balloon the testing matrix to almost impossible levels. Either way, we're now benchmarking the AMD RX 6800 vs. the RTX 3070, joining our existing benchmarks of the RX 6800 XT vs. the RTX 3080 and 3090. Additional testing includes power consumption of the new RDNA GPUs and Ampere GPUs, overclocking performance, thermals, fan RPM response, frequency behavior, and more. This will help you determine the best GPU for your gaming PC in 2020.

It will be interesting to see what availability and prices are like in a week when the AIB partner cards are available for sale. I was looking at the Houston Micro Center online as it is around 170 miles (280km) away (340 miles, 560km round trip) and Micro Center (Houston) are:
showing Ryzen 5600x in stock 10+ (the others are out of stock),
showing no listings at all for the RX 6800 or RX 6800 XT (they do not even show as out of stock).
But, they have the i9-10900k on sale for 540, 10850k at 400
ZERO RTX 3080's - that is ZERO stock TWO MONTHS after launch - priced 700, most versions are priced 730 to 850
ZERO RTX 3070's (keep in mind they were originally supposed to launch Oct 15th - over a month ago) and the 3070 that are out of stock are priced at 500, 540, 550, 570, 600 and 630... but no stock at all.
If AMD and the AIB partners can provide any level of stock in less than a month this could be a huge win for AMD... we will have to wait and see what happens with prices and stock?

Using DLSS means you're not, as you say, actually playing at the target resolution. The only way to do a fair comparison is to run the AMD card at the lower resolution (i.e. the one the nVidia card is actually rendering at) with the best upscaling possible at this time, which is just normal scaling with sharpening. Then you have to compare both performance and image quality, and not just in a handful of still images, but while playing.
When AMD has a more sophisticated upscaler, then you can put that head-to-head against DLSS. Needless to say, such a comparison would also be pointless without an image quality assessment, with the same requirements that actual play is compared rather than just a selection of static images. One of the big problems with DLSS is that it's a temporal algorithm which causes flickering artifacts, which you can't see in a screenshot.
Until then, you're comparing apples and oranges the way you've done it.

nvidia gonna on 3rd generation Rt and DLSS...hopper gonna look more successful as ampere...whats happening to AMD...its performance is all over the place ..what is 6800 competing with ?? reason nvidia getting more success...hardware features making easier for linux developers than amd requires software level skills from developers when linux do not have nothing to provide and vulkan do not come with software processing as microsoft comes with in DX12 ultimate but thats lazy approach for gpu developers ...sony have to make their own software processor for RAy tracing due to RDNA2 lack any hardware processor to do any extra ray tracing features...Microsoft only got reflections and fake lighting effect still...thats directx i know of...

People seems to misunderstand what Optimization means; save cheap codding errors and bad practices, optimization just means smoke and mirrors , showing something very similar in APAREANCE to other thing, just cutting the right details to improve performance a little; maybe you could argue that and NVIDIA-optimized game would tend to use API calls that would benefit a little more Nvidia cards, but is not magic.... AMD titles would use light RT features like shadows, for example, and Nvidia would go all the way with Global Illumination and Reflections, which are more expensive.... Those effects benefit using dedicated RT cores more that the mixed approach of AMD...

Hey Steve, what are your thoughts on future architecture optimisations at a game code/driver level? In specific, both the new gen consoles use AMD hardware, so one would assume a resizable BAR function would be less of a toggleable feature, and more of a baked in optimisation for those platforms.
Furthermore, developers will have to optimise for AMD's RT architecture for the consoles, do you think this will transfer over to PC in uplift as it all matures?
Maybe worth a short talking head piece or article, after you guys get some well deserved rest of course.

HELP THE PRICING FOR ALL THE NEW AMD GPUS and CPUS IS VERY HIGH NOT EVEN CLOSE !!
i can't buy anything even if they resolve the problems of availability
So we need you condemn this actes (their source!!)
we need amd to take actions agaist this huge probleme
I can wait for availibility but we need the pricing to go down
Otherwise am not buying anything !!!!!!
RYZEN 9 5900X is listing for 1100 euro on amazon !!!!!
rx 6800 xt is listing for 800 euro 830 dollars OMG THIS IS UNACCEPTABLE

Gamers Nexus , i guess the warranty sticker is something after all, i tried to RMA my card, from ass-rock and they denied my RMA, because i changed the thermal paste. i argued with them about it, but they claim there is no such law, and i lost with the BBB with them to so far, im still fighting it, but not easy for something like this, you wouldnt think it be that big of a deal. MSI an others dont enforce it, i guess it just depends on the company, but i have it in writing an everything from them about it

The thing is, AMD could easily add 100 to whatever price they were planning on just because of how hype was the 3000 series and how everyone was disappointed not being able to get one, so to get something that Is actually (was) available for a bit more and with same (ish) performance. They would have been sold out even if there was meteor heading to earth when launched.

It makes no sense to not spend the extra 80 and go up to the 6800XT if you are considering an AMD card. Likely what AMD is intending here. Also the argument about people not being able to dish out 80 more dollars make no sense because in general, people who have a hard time dishing out 80 more wouldn't be looking at a sub 580 card to begin with!!!

I wonder, do you use any automation to do all this testing (i.e. would you run a huge batch file which would re-run the games multiple times and record the output)? Or is it all manual work? If the latter, I really beg you to do some automation, that would save you from working those crazy hours!
