AMD Radeon RX 6800 XT Graphics Card Review

AMD has been defying the legal guidelines of likelihood given how they’ve managed to get a number of profitable product launches over the previous three years. The key takeaway from these launches being the numerous efficiency increments between launches, that too, tangible ones. With the latest AMD Ryzen 5000 collection (Ryzen 9 5950X and 5900X) CPUs, the corporate has even managed to equal Intel’s tenth Gen processors in a whole lot of points and the identical is anticipated with the ‘RDNA 2’-based Radeon RX 6000 collection. NVIDIA’s RTX GPUs benefit from the lion’s share of the market and the Radeon RX 6000 collection GPUs are anticipated to assist AMD seize a bigger piece of the pie. Today’s launch consists of the Radeon RX 6800 XT and the RX 6800 which are each high-end GPUs and the one GPU left to be launched is the Radeon RX 6900 XT which is meant to launch in December.

RDNA 2 brings a number of new options to the desk which have vital efficiency implications. The Compute Units have been modified to include a new render pipeline which additionally embody hardware-accelerated ray-tracing capabilities that solely NVIDIA had for the final era. There can also be the new Smart Memory Access characteristic which helps the CPU tackle bigger chunks of GPU reminiscence and thereby, enhance efficiency. However, that is made attainable due to the resizable BAR characteristic that’s a part of the PCIe specification and might be simply replicated by NVIDIA by way of software program updates. Then there’s Direct X 12 Ultimate help which once more brings the characteristic set of AMD in the identical league as NVIDIA’s. So the competitors is sort of actual and intense. All that’s left on the desk is driver stability and AIB provide. We’ll get to listen to much more about these as soon as the playing cards hit the cabinets. We didn’t face a lot points with the drivers other than some glitches which have all been already recognized by AMD. Let’s take a better have a look at the specs beneath.

AMD Radeon RX 6800 XT / 6800 Specifications

The AMD Radeon RX 6000 collection GPUs use the identical 7nm course of node so one wouldn’t count on a lot energy financial savings. TSMC has been engaged on bettering the node so a few of these enhancements will lead to minor effectivity enhancements. AMD’s architectural enhancements contribute to the remainder of the efficiency beneficial properties. We’ll take a detailed have a look at that later. The two playing cards that we have immediately are utilizing the identical GPUs going by the core configurations. The efficiency distinction is led to by the variety of lively Compute Units. We’ve seen cross-flashing of firmware up to now and that might very effectively work on this case as effectively. We haven’t cross-flashed the firmware on the GPUs but, so we will’t affirm the identical.

The key distinction between the Radeon RX 6800 XT and the RX 6800 comes all the way down to 12 Compute Units. Even the video reminiscence has been retained throughout the 2 GPUs so that you’re by no means going to be constrained for video reminiscence and two playing cards ought to simply deal with ridiculous resolutions so long as there’s sufficient horsepower throughout the GPU to again them up. RDNA 2 now has one Ray Accelerator per CU, so there needs to be a definite distinction in ray-tracing efficiency between the 2 playing cards. How that compares to NVIDIA will be explored within the efficiency part.

With the new set of benchmarks, we’ve featured a number of the older GTX 10 collection playing cards alongside with many of the RTX 20 collection playing cards together with the Super playing cards. Last yr’s AMD RX 5000 collection playing cards are current to assist gauge the generational enchancment of RDNA2 towards RDNA. Also included are the new RTX 30 playing cards so you may get a good suggestion of how the RDNA2 playing cards go up towards NVIDIA’s latest GPUs. And for the reason that launch home windows of the 2 playing cards are overlapping, this record couldn’t have been extra even. We have eliminated the older AMD Vega playing cards since we haven’t retested them in a very long time and a whole lot of driver-related efficiency enchancment can’t be gauged with out a retest. Like all the time, we have a bit for artificial benchmarks in addition to gaming benchmarks with loads of charts to showcase variations. Coming to the rig, we’ve needed to take a look at the playing cards on Intel in addition to AMD processors contemplating the inclusion of the new Smart Memory Access characteristic. We’ve tried to maintain the rigs as comparable as we might. Here are the 2 rigs that we’re operating our benchmarks on.

Some of those playing cards have been sourced from pals owing to the very fact that the present lockdown state of affairs has made it extraordinarily tough to get graphics playing cards in time for the benchmarks. Let’s begin with the artificial benchmarks.

3DMark

In 3DMark, we choose the Fire Strike Ultra benchmark for the reason that Extreme and regular runs have began producing ridiculous scores with newer GPUs. The other benchmark inside 3DMark which we use is Time Spy and we run each, the traditional run and the acute run. Here, we’re showcasing Fire Strike Ultra and Time Spy scores. The Radeon RX 6800 XT comes actually near the NVIDIA RTX 3090. Considering that the latter is a $1,499 card, it is a big efficiency achieve. The Radeon RX 6800 isn’t that far behind. The RTX 3080 scores greater than the RX 6800 but it surely additionally prices much more.

Time Spy replicates the identical outcomes. The RTX 3090 continues to be on the very top of the scoreboard with the RTX 3080 in tow and the RX 6800 XT proper behind it. Then comes the RX 6800 and after a good hole lies the RTX 3070.

Basemark GPU

Basemark GPU is a pleasant benchmark to check the efficiency of various graphics APIs between playing cards. We can use the identical textures with OpenGL, Vulkan and DirectX 12 to see if the graphics card excels at any explicit API greater than the remainder or if the efficiency is constant throughout the board. The RX 6800 comes third, behind the RTX 3090 and the RTX 3080. NVIDIA playing cards have a transparent benefit on this benchmark and the hole between the RTX 3070 and the RX 6800 has narrowed. What stood out for us was the OpenGL efficiency because the RDNA 2 playing cards tanked in comparison with the competitors and are displaying solely a meagre generational enchancment.

IndigoBench

This is the latest artificial to be added to our take a look at suite. IndigoBench relies on the Indigo 4 rendering engine that’s accessible for fashionable software program similar to SketchUp, Blender, 3ds Max, Cinema 4D, Revit and Maya. It makes use of OpenCL and may benchmark each, the CPU and GPU collectively or individually. We choose to check simply the GPU with the software program and the rating offered is by way of .M samples/s’. The RTX 3090 and the RTX 3080 preserve a lead right here whereas the RX 6800 XT and RX 6800 are available in on the third and fourth positions. Performance distinction between the RX 6800 XT and RX 6800 can also be fairly slim.

Unigine SuperPlace

Unigine SuperPlace is the other fashionable DX11 benchmark which we choose to make use of alongside 3DMark. We run it on the Extreme Quality preset and use the rating metric for delineating the efficiency between graphics playing cards. The NVIDIA playing cards retain the lead once more however with a a lot slim margin. The RX 6800 XT and the RTX 3080 are nearly equal on this benchmark.

Borderlands 3

Gearbox’s latest sport within the Borderlands franchise which makes use of Unreal Engine 4 and permits you to change between DirectX 11 and 12. The sport has an inbuilt benchmark which takes you thru an array of worrying eventualities. The DirectX 12 model is sort of flaky and we choose to make use of the DirectX 11 API while benchmarking the sport and all our current knowledge relies off the DX11 model so there’s no level switching now.

Death Stranding

Hideo Kojima’s Death Stranding has been a current addition to the PC scene and had been a PlayStation unique till July 2020. Being a console sport, the sport engine is sort of optimised to make use of the scarce sources one will get with consoles. However, when 505 Games ported the sport to PC, you wouldn’t find yourself calling the sport a console port. The Decima sport engine is able to rendering as much as 4K and may use excessive dynamic-range imaging and can also be geared for the upcoming next-gen PlayStation console. It’s additionally the identical engine utilized by Horizon Zero Dawn.

Shadow of the Tomb Raider

We run Shadow of the Tomb Raider in DirectX12 mode. It finally ends up consuming just a little extra reminiscence as most video games that help each DirectX 11 and DirectX 12. The preset is about to the very best high quality and HBAO+ enabled. The ingame benchmark device takes us by way of a number of scenes which characteristic open areas in addition to closed areas with a number of world element other than the central character.

Pricing

The AMD Radeon RX 6800 is priced at INR 45,999 + Taxes and the pricing for the RX 6800 XT will be revealed in a while twenty fifth November, 2020. With Taxes, the RX 6800 comes out to be INR 54,278 which is lesser than the RTX 3070 from NVIDIA however a teensy bit increased than the direct foreign exchange conversion. So you have to provide to AMD for bringing their Indian costs all the way down to smart ranges not like their RX 5000 collection launch. NVIDIA’s official pricing for the RTX 3070 will not be being adhered to by any of the AIBs for his or her lower-end SKUs with the exception of certainly one of two AIBs. It needs to be fascinating to see how AMD’s AIBs keep on with the pricing. Rumours from the US and EU market paint a dire image of the launch provide for the Radeon RX 6000 playing cards which places it in the identical boat as NVIDIA since you possibly can barely get any of their new RTX 30 playing cards. And even lesser might be obtained for the best pricing. So while we will all rejoice that the discrete graphics market has develop into aggressive, it’ll be a while earlier than any of us can get our arms on a new retail card.

Verdict

AMD has performed it. The new ‘RDNA 2’-based Radeon RX 6000 graphics playing cards are very aggressive, priced a lot decrease and are not power-hungry for the efficiency that they ship. We solely have the pricing for the RX 6800 which does work out effectively for the Indian market given that the GPUs do have the efficiency to again it up. What stays to be seen is how the RX 6800 XT will be priced. We’ll learn about that in a weeks time and hopefully, it is competitively priced in comparison with the RTX 3080 or equal. Performance clever, these playing cards do effectively in most benchmarks that we ran and so they’re cheaper than the competitors. That’s a really wholesome and consumer-centric positioning for AMD. Let’s simply hope that there’s sufficient provide within the market.
