With the launch of PS5 and Xbox Series X only a few weeks away, AMD fans have been champing at the bit to see what team red has for PC gamers with its new RDNA 2 architecture. RX 6000-series GPUs are the answer, and they’re exciting. The new RX 6800 XT is positioned to challenge Nvidia’s recent RTX 3080, and at $50 less, it’ll save you a little money, too.
More importantly, though, AMD’s next-gen GPUs are arriving at an opportune time, as stock shortages persist for Nvidia’s latest cards. Historically, team green has always won the performance war, leaving AMD to compete on price. AMD may do both this time around, especially with the new features AMD is introducing into its RX 6000-series cards.
In this guide, we’re going to cover the RX 6800 XT versus the RTX 3080 so you know which card to pick up for your next build.
Pricing and availability
AMD’s new RX 6800 and 6800 XT launch on November 18 for $579 and $649, respectively. At only $50 less than the RTX 3080, the 6800 XT probably won’t win over many users purely based on price, though it’s at least staying competitive, especially compared to 3080 board partner cards.
At the end of October 2020, however, the RTX 3080 isn’t in stock anywhere. Nvidia has struggled to get a handle on its 30-series launch, following reports of poor yields of the Samsung 8nm node powering Nvidia’s new cards. The RTX 3080 is sold out everywhere right now, and it’ll likely stay that way well into 2021.
Historically, TSMC — who’s behind the 7nm node in the RX 6800 XT — has been able to meet demand with high-volume manufacturing. Especially moving into the holiday season, AMD could steal back some significant market share from Nvidia if it can keep cards on shelves. The RX 6800 XT is already $50 less, and if AMD’s performance numbers are anything to go by, it matches the 3080 in a lot of games.
Specs and performance
It’s hard directly comparing AMD and Nvidia GPUs purely based on specs, and that’s not changing with AMD’s new RX 6000 cards. That said, there are some aspects that are more comparable. We can see some stark differences between the 6800 XT and RTX 3080 in terms of memory. The 6800 XT has 16GB to the 3080’s 10GB, though Nvidia’s card uses newer, faster GDDR6X memory.
|RX 6800 XT||RTX 3080|
|Interface||PCI Express 4.0||PCI Express 4.0|
|Cores||4,320 Stream processors||8,704 CUDA cores|
|Memory||16GB GDDR6||10GB GDDR6X|
According to AMD’s numbers, the 6800 XT matches the RTX 3080 at 4K in a number of games. It depends on the game, but AMD’s newer card is within a few frames. The 6800 XT beats the 3080 by about 10 frames in Battlefield V, for example, but lags behind a few frames in The Division 2. At 1440p, the gains are exaggerated in Nvidia’s favor, with Battlefield V shooting up to nearly 200 fps.
These are AMD’s benchmarks, so we’ll need to wait for third-party benchmarks to draw any real conclusions, but they are promising nonetheless.
Based on our testing of the RTX 3080, we know AMD’s competing numbers are at least close. In Battlefield V, the card reached 97 fps at 4K with Ultra settings, and 147 fps at 1440p. The 1440p numbers are a little high in AMD’s charts, though 4K performance is around what we’d expect. If the 6800 XT can match the performance of the RTX 3080, we could see AMD finally steal back some market share, especially if availability is better.
AMD is introducing two new features with the launch of RX 6000 GPUs that could further boost performance. Rage Mode is a new one-click overclocking tool built in to the Radeon software, allowing you to get the most out of your graphics card with minimal tweaking. The exciting new addition, however, is Smart Access Memory. AMD’s upcoming Ryzen 5000 processors can take full control of RX 6000-series GPUs. According to AMD’s benchmarks, using both can offer up to a 13% performance improvement at 4K.
This is highly dependent on the game, it seems. Although AMD showed off a 13% improvement in Forza Horizon 4, Doom Eternal only saw a 2% improvement.
Ray tracing and other features
AMD was quick to highlight hardware support for DirectX 12 during its RX 6000 reveal event, though didn’t provide any performance numbers. As we saw with Nvidia’s RTX 20-series GPUs, ray tracing takes a huge toll on performance. AMD didn’t share any performance numbers with ray tracing enabled — at least none that were explicitly stated — so although we’re hopeful, we’re remaining skeptical.
Nvidia has gotten a grip on ray tracing and features like DLSS with 30-series cards. DLSS — Nvidia’s A.I.-powered upscaling technology — has seen massive improvements in recent years. The new RTX 3090, for example, is capable of hitting 8K near 60 fps in most games with some help from DLSS.
DLSS and ray tracing have been, for the past few years, a big reason to choose team green. That’s changing. Although we’ll need to validate ray tracing performance once the RX 6800 XT hits the streets, AMD is offering a compelling list of features in its new range of graphics cards. The FidelityFX suite includes, along with screen-space reflections and other ray-tracing features, Contrast Adaptive Sharpening (CAS) and variable rate shading.
The $50 difference
Between the two — and a denoiser — the RX 6800 XT has something similar to DLSS. Feature for feature, AMD and Nvidia are finally on a level playing field. That doesn’t guarantee the same level of performance across the two brands, though. Like ray-traced reflections, we’re hopeful for the RX 6800 XT with these features, though we’ll need to wait to validate performance with them enabled.
