AMD Radeon RX 6900 XT Graphics Card OpenCL Score Leaks

AMD has launched its RDNA 2 based graphics cards, codenamed Navi 21. These GPUs are set to compete with NVIDIA's Ampere offerings, with the lineup covering the Radeon RX 6800, RX 6800 XT, and RX 6900 XT graphics cards. Until now, we have had reviews of the former two, but not the Radeon RX 6900 XT. That is because the card is coming at a later date, specifically on December 8th, in just a few days. As a reminder, the Radeon RX 6900 XT GPU is a Navi 21 XTX model with 80 Compute Units that give a total of 5120 Stream Processors. The graphics card uses a 256-bit bus that connects the GPU with 128 MB of its Infinity Cache to 16 GB of GDDR6 memory. When it comes to frequencies, it has a base clock of 1825 MHz, with a boost speed of 2250 MHz.

Today, in a GeekBench 5 submission, we get to see the first benchmarks of AMD's top-end Radeon RX 6900 XT graphics card. Running an OpenCL test suite, the card was paired with AMD's Ryzen 9 5950X 16C/32T CPU. The card managed to pass the OpenCL test benchmarks with a score of 169779 points. That makes the card 12% faster than RX 6800 XT GPU, but still slower than the competing NVIDIA GeForce RTX 3080 GPU, which scores 177724 points. However, we need to wait for a few more benchmarks to appear to jump to any conclusions, including the TechPowerUp review, which is expected to arrive once NDA lifts. Below, you can compare the score to other GPUs in the GeekBench 5 OpenCL database.

Far Cry 6 Features DirectX Ray Tracing, FidelityFX CAS and Variable Rate Shading

Not to be outdone in comparison to almost all other AAA game releases in recent times, Far Cry 6 has recently been delayed from its February 18th release to May 25th 2021. However, that extra time may come to serve the game nicely, in that it may allow for all the planned features to be integrated. As part of AMD's partner showcase, Ubisoft has revealed that Far Cry 6 will make extensive use of DirectX 12 Ultimate features, featuring raytracing, AMD's Contrast Adaptive Sharpening (CAS), Variable Rate Shading (VRS), as well as Hybrid SSR (Stochastic Screen Space Reflections).

Ubisoft's head of 3D programming Oleksandr Polishchuk had this to say: "We were very impressed with the latest AMD technologies and joined forces to bring FidelityFX CAS, DXR raytracing and Variable Rate Shading to Far Cry 6. We are working together to ensure a smooth 4K viewing experience. This requires a lot of bandwidth, memory, and a Radeon RX 6000 with Infinity Cache that can handle it easily while maintaining high FPS rates." Check out the AMD partner showcase video below.

Possible Radeon RX 6700 XT Specs Surface, 12GB the New Mid-Range Memory Size?

AMD could follow up on its RX 6800 series and RX 6900 XT launches with the RX 6700 series, which logically succeeds the RX 5700 series, and competes with NVIDIA's RTX 3060/Ti. Patrick Schur on Twitter, who has a high hit-rate with specs of upcoming AMD products, put out possible specs of the RX 6700 series. Both are based on the new "Navi 22" silicon, with an interesting set of specifications.

Apparently 12 GB could be AMD's new memory amount for the mid-range. It's unknown whether the 12 GB is running over a 192-bit wide memory interface (6x 16 Gbit chips), or whether AMD is using mixed-density chips over a 256-bit wide memory bus (think 4x 16 Gbit and 4x 8 Gbit), because even the fastest JEDEC-standard GDDR6 chips, running at 16 Gbps, would only yield 384 GB/s memory bandwidth, which is less than the 448 GB/s the RX 5700 series enjoy. Perhaps an Infinity Cache is deployed to make up the difference?

Sapphire Unveils Reference-design Radeon RX 6800 XT and RX 6800

Unlike NVIDIA, AMD still relies on its add-in board (AIB) partners to sell reference design (made by AMD) graphics cards, and Sapphire just announced its lineup. The company unveiled its reference-design Radeon RX 6800 XT and RX 6800 cards. The RX 6800 XT is characterized by its triple-slot cooling solution, while the RX 6800 makes do with a slimmer dual-slot one. Both cards are based on the 7 nm "Navi 21" silicon and feature 16 GB of 16 Gbps GDDR6 memory over a 256-bit wide memory interface, cushioned by 128 MB of on-die Infinity Cache.

The RX 6800 XT is configured with 72 out of 80 RDNA2 compute units on the "Navi 21" silicon, working out to 4,608 stream processors, 72 ray accelerators, 288 TMUs, and 128 ROPs. The engine clock of the RX 6800 XT boosts up to 2.25 GHz. The RX 6800, on the other hand, features 60 out of 80 RDNA2 compute units, which make up 3,840 stream processors, 60 ray accelerators, 240 TMUs, the same 128 ROPs, and the same memory subsystem as the RX 6800 XT. Given that these are reference cards, Sapphire could price them at AMD's baseline, with the RX 6800 XT going for $649, and the RX 6800 at $579.

AMD Navi 21 XT Seemingly Confirmed to Run at ~2.3, 2.4 GHz Clock, 250 W+

AMD's RDNA2-based cards are just around the corner, with the company's full debut of the secrecy-shrouded cards being set for October 28th. Rumors of high clocks on AMD's new architecture - which were nothing more than unsubstantiated rumors up to now - have seemingly been confirmed, with Patrick Schur posting on Twitter some specifications for upcoming RNDA2-based Navi 21 XT. Navi 21 XT falls under the big Navi chip, but likely isn't the top performer from AMD - the company is allegedly working on a Navi 21 XTX solution, which ought to be exclusive to their reference designs, with higher clocks and possibly more CUs.

The specs outed by Patrick are promising, to say the least; that AMD's Big Navi can reach clocks in excess of 2.4 GHz with a 250 W+ TGP (quoted at around 255 W) is certainly good news. The 2.4 GHz (game clock) speeds are being associated with AIB cards; AMD's own reference designs should be running at a more conservative 2.3 GHz. A memory pool of 16 GB GDDR6 has also been confirmed. AMD's assault on the NVIDIA 30-series lineup should embody three models carved from the Navi 21 chip - the higher performance, AMD-exclusive XTX, XT, and the lower performance Navi 21 XL. All of these are expected to ship with the same 256 bit bus and 16 GB GDDR6 memory, whilst taking advantage of AMD's (rumored, for now) Infinity Cache to make up for the lower memory speeds and bus. Hold on to your hats; the hype train is going full speed ahead, luckily stopping in a smooth manner come October 28th.
