AMD Ray Tracing
I was certainly excited when AMD declared each of the specs and neat characteristics of the 6000-series graphics cards in the end of October, albeit doubtful of what type of ray tracing performance AMD’s latest GPUs could have. AMD was silent concerning the ray tracing performance, and it might have been since its cards would not conquer Nvidia 3000-series cards.
Unfortunately, that was the situation based on my testing. But do not discount RDNA2 rather yet. The RX 6800 XT and RX 6800 reviewed matched or surpassed the RTX 3080 and RTX 3070 in almost all of the games I analyzed. All these are still some seriously fantastic GPUs.
Traditionally, the most significant element of a brand new GPU is the number of frames it could pump out. However with the accession of new features such as Smart Access Memory and Rage Mode, what might have been two straightforward graphics cards are far more complicated.
The strengths and weaknesses of this RX 6800 XT and RX 6800 have much less to do with frames each second and much more to do with what an individual currently has in their rig.
If you end up agonizing over heading team green or group crimson, oh man do I catch it? Besides some 50 percent per watt performance growth over the prior generation, it has added more calculate units (CUs) and more shades, and something named Infinity Cache: 128 MB of dedicated distance to assist optimize memory bandwidth and latency.
This 128 MB ought to continue to keep all the framebuffer, z-buffer, and latest flaws cached. Fundamentally, important visual information that would typically be saved from the GPU’s VRAM gets transferred here, freeing up that space from the VRAM for different data to accelerate rendering times.
In training, I am not certain when I noticed that while conducting gambling benchmarks or loading in from 1 scene into another, however I did notice just how fast the picture on my display would reload once I changed from 1 resolution to another. Ordinarily, the display goes black for a second or two while the GPU does exactly what it should perform, but that did not occur in certain games.
For your Smart Access Memory evaluations I swapped out the aforementioned CPU and motherboard to get a Ryzen 9 5950X along with an Asus ROG Crosshair VIII Hero motherboard.
But real fast, a notice for all of the testing that has been done on this AMD motherboard: ” I could just place the RAM frequency to 3200 Hz, though its high frequency is 3600 Hz.
The most recent BIOS for this motherboard now has a glitch that prevents the machine from booting if the DOCP preset profile is chosen, which overclocks your own RAM to its highest possible frequency. AMD is now aware of the problem and will work to fix it, a spokesperson told me.
The preceding BIOS version is nice, however, the newest version is required to utilize Smart Access Memory, and therefore it was a small Catch-22 together with my testing.
On the other hand, the reduced frequency had little impact on performance because you’ll notice in the graphs with outcomes in the AMD-configured system farther down. I had zero problems with the Intel system.
We do not normally use 3DMark within our benchmark suite, but in this case it is useful as a starting point before getting into all of the thorough gaming benchmarks. It’s amazing to see AMD have such a significant lead over Nvidia, and it is apparent that AMD has improved over its own Radeon cards enormously out of its past generation.
It has not had such powerful performance in comparison to Nvidia earlier, and the modifications it made for its GPU structure have obviously repaid.
The RTX 3080 keeps a generous direct from the Port Royal evaluations, along with the RTX 3070 isn’t too much behind the RX 6800 XT. The RX 6800’s ray tracing performance is kind of lackluster, more akin to the performance of possibly the RTX 2080 or even 2070–fairly obvious as soon as you begin digging into person games.
AMD’s brand new GPUs normally match or surpass Nvidia’s new GPUs in 1440p and 4K. There are a number of outliers, such as both RX 6000 cards can not appear to out-perform the RTX 3000 cards in Command and Metro Exodus, however apart from that performance is generally included 5 fps or even a bit more, and with Smart Access empowered, frame rates are off the charts–almost literally.
But, things begin to get complex when ray tracing and/or Smart Access is switched on. Theoretically, AMD’s brand new cards must be compatible with current ray tracing enabled games, and they’re for the most part.
But, ray tracing won’t work with a match such as Wolfenstein: Youngblood since the ray tracing because match is proprietary to Nvidia; the DLSS is incorporated together with all the ray tracing, and because DLSS is Nvidia’s own framework rate-boosting, picture sharping technologies, AMD’s cards cannot utilize it.
The choice does not even appear in the movie settings. I didn’t experience any problems in 1080p. Even stranger, that this dilemma was only present once I paired a Radeon card using an AMD chip. The difficulty was non-existent once I analyzed the very same cards in my Intel system.
As for Smart Access Memory–it is a new attribute from AMD that permits a Ryzen CPU along with a Radeon GPU to”speak” directly to each other and access each other’s memory without needing to go via your system DRAM first.
All this means that Smart Access Memory ought to enhance game frame rates while locking you to a all AMD system. And it certainly works, but additionally it only works with specific games, just like Nvidia DLSS is only available in certain games also.
If you are wondering what games will gain from this Smart Access, start looking for the enormous AMD Ryzen/Radeon emblem once the game loads. This will often indicate whether this game will profit from the new attribute.
Though not all of the time, DLSS additionally enhances the visuals, however, so technically it is the better of both. But just more than 20 games encourage DLSS in the moment with more on the road every year.
Sure, AMD has things such as CAS (Contrast Aware Sharpening), but people who do not really enhance frame rates in precisely the exact same manner that DLSS does, rather than every game works with these attributes.And if you are wondering why I have not talked about Rage Mode. . .well for starters, it is only available on the RX 6800 XT and it does not actually give much of a performance increase, possibly a couple of frames in the most.
Thus, the perfect way to provide some games with no DLSS a tiny performance increase without overclocking is using Smart Access–so you’ll have to get an all-AMD system. However, an all-AMD system ensures you’re going to be overlooking ray tracing performance, which brings me into another round of graphs. (I stated there were likely to be plenty of graphs, did not I?)
Nvidia still gets the ideal ray tracing performance, along with the RTX 3080 remains the very best GPU to get if you would like stunning images at 4K 60fps for about $700. And that is logical because Nvidia is 1 generation before AMD with respect to this attribute. The RX 6800 XT is fantastic for 1080p and 1440p ray tracing, exactly enjoy the RTX 2080 Ti, however it cranks the exact same magnificent visuals as Nvidia’s cards.
If you have already spent in a 4K screen and many ray tracing games, it may make more sense that you stay with Nvidia. But in case you have just a 1440p monitor or maybe not a great deal a ray tracing games, AMD may create the most sense rather, particularly in the event that you’ve already invested in a brand new Ryzen 5000 series desktop chip.
That is actually the bonus however, is not it? In theory, it is a good one also. This Smart Access fps boost that is only able once you set an AMD GPU having an AMD CPU means greater performance, ray tracing or not, though it’s limited to a few games and sometimes just specific resolutions in these games.
Nvidia’s DLSS will provide pick games a performance increase whatsoever resolutions and is not CPU dependent in any way. It is a more challenging argument for its 580 RX 6800 that is $80 over the RTX 3070. It will have greater foundation performance, but I am not sure it seems just like $80 better foundation performance.
If you are the type of person who only needs to smack a GPU in your PC and call it a day, then you cannot go wrong with AMD’s 6000 cards. However, the deeper you dive in to ray tracing performance and BIOS-level performance boosts, those cards begin not to seem as sweet.
I am sure AMD will patch anything bugs have been bogging down the most recent BIOS version, enhance its Smart Access attribute, and fix whatever the hell is occurring with Control. Regrettably, that isn’t enough of a gap for me to state Nvidia or AMD is much better overall. Finally it comes down to if you would be pleased with these fresh AMD cards. I know I’d be.
