AMD simply introduced three subsequent era Radeon graphics playing cards: RX 6800, RX 6800 XT, and RX 6900 XT. They compete instantly with NVIDIA’s RTX 3000 collection.
This RX 6000 collection is constructed on the identical RDNA 2 structure used within the upcoming PlayStation 5, Xbox Collection X, and Xbox Collection S.
RDNA 2 builds on final yr’s RDNA, utilizing TSMC’s “enhanced” 7nm fabrication course of to allow 30% larger clock frequencies.
It additionally introduces accelerated ray tracing in addition to ‘Infinity Cache’, a brand new 128MB extremely quick cache just like the cache in CPUs.
The Playing cardsCard RDNA2 Compute Models Enhance Clock Pace Value RX 6800 60 2105MHz $579 RX 6800 XT 72 2250 MHz $649 RX 6900 XT 80 2250 MHz $999
All three playing cards have 16GB of GBBR6 VRAM. Each AMD and NVIDIA often distinguish fashions with VRAM, so that is an attention-grabbing technique to take.
RX 6800 is positioned to compete with NVIDIA’s RTX 3070. AMD’s RRP is $80 larger, however the RTX 3070 has simply half the VRAM. That ought to assist the RX 6800 higher help future extremely excessive decision headsets.
RX 6800 XT is positioned to compete with RTX 3080. AMD is $50 cheaper right here.
RX 6900 XT is probably the most highly effective AMD card ever. It’s $500 cheaper than NVIDIA’s RTX 3090, and has 8GB much less VRAM.
AMD’s Efficiency Claims
AMD is making large claims about RDNA2’s efficiency:
On this slide instantly evaluating RX 6800 XT to NVIDIA’s RTX 3080 at 1440p it’s proven as quicker in Battlefield V, Borderlands three, Name of Obligation, Doom Everlasting, Forza Horizon four, Gears of Struggle 5, Resident Evil three, Shadow of the Tomb Raider, and Wolfenstein: Younger Blood.
Apparently, AMD included The Division 2 the place the cardboard falls behind barely. Nonetheless, given it’s $50 cheaper this seems to be like AMD’s best GPU launch in years.
We’ll maintain a detailed eye for the primary VR-specific benchmarks when these playing cards launch, as common monitor efficiency doesn’t fairly map on to enjoying VR.
Oculus Hyperlink / Digital Desktop Concerns
For regular PC gaming, selecting between NVIDIA and AMD is often only a matter of evaluating the uncooked efficiency and value. For native PC VR headsets that use DisplayPort or HDMI that is additionally largely the case.
When utilizing an Oculus Quest headset in PC mode, both formally by way of a USB cable or wirelessly by way of the app Digital Desktop, your GPU doesn’t simply ship frames uncooked. As a result of WiFi and USB have significantly much less bandwidth, the video stream is compressed utilizing your graphics card’s built-in video encoder.
Digital Desktop developer Man Godin advised us the video encoder in AMD’s present graphics playing cards has each larger latency and worse picture high quality than NVIDIA’s 2018 Turing (now changed by Ampere). We’ve heard this from Oculus Hyperlink customers too.
It’s at the moment unknown whether or not that is solved or improved on this new RX 6000 collection, however for those who’re planning on utilizing one with Quest we’d advocate ready for that to be examined earlier than shopping for.
What is going to assist your Oculus Hyperlink expertise although is the inclusion of a USB Kind-C port and USB controller in all three introduced playing cards. NVIDIA had this for some larger finish RTX 20-series playing cards however dropped the function within the new 30-series.
Meaning if you need full visible high quality by way of USB three.zero, you may plug your Quest instantly into the graphics card with out having to fret in case your motherboard’s USB controllers are overloaded by different units.
