When AMD introduced RDNA 2 architecture and higher-end Navi 21 GPU SKUs, it was only a matter of time before the company launches these GPUs inside professional-grade graphics cards. Today, thanks to the Chiphell forums, we have pictures and some specifications of AMD's upcoming Radeon Pro workstation graphics card. Pictured below is a new RDNA 2 based design that features AMD's Navi 21 GLXL GPU SKU. The new GLXL GPU SKU is supposed to be rather similar to the Navi 21 XL GPU found inside AMD's Radeon RX 6800 XT graphics card, judging by the number and arrangement of capacitors on the back of the card.

When it comes to memory, the upcoming Radeon Pro workstation card is featuring 16 GB of VRAM, likely a variant of GDDR6 found on gaming-oriented graphics cards from RDNA 2 generation. When it comes to cooler design, the Radeon Pro graphics card has a blower-type cooler helping tame the Navi 21 GLXL GPU. Given that blower-type coolers are suitable for situations with less airflow, the TDP of this card could be around or under 250 Watts. You can take a look at the card below, however, do note that it is an engineering sample and the final product can look a bit different.

AMD has recently launched its Radeon "Big Navi" 6000 series of graphics cards, making entry to the high-end market and positioning itself well against the competition. The "Big Navi" graphics cards are based on Navi 21 XL (Radeon RX 6800), Navi 21 XT (Radeon RX 6800 XT), and Navi 21 XTX (Radeon RX 6900 XT) GPU revision, each of which features a different number of Shaders/TMUs/ROPs. The highest-end Navi 21 XTX is the highest performance revision featuring 80 Compute Units with 5120 cores. However, it seems like AMD is preparing another similar silicon called Navi 21 XTXH. Currently, it is unknown what the additional "H" means. It could indicate an upgraded version with more CUs, or perhaps a bit cut down configuration. It is unclear where such a GPU would fit in the lineup or is it just an engineering sample that is never making it to the market. It could represent a potential response from AMD to NVIDIA's upcoming GeForce RTX 3080 Ti graphics card, however, that is just speculation. Other options suggest that such a GPU would be a part of mainstream notebook lineup, just like Renoir comes in the "H" variant. We have to wait and see what AMD does to find out more.

AMD's Radeon RX 6000 series graphics cards, based on the RDNA2 graphics architecture, will see the introduction of the company's first DirectX 12 Ultimate graphics cards (featuring features such as real-time raytracing). A VideoCardz report sheds light on the specifications. The 7 nm "Navi 21" and "Navi 22" chips will power the top-end of the lineup. The flagship part is the Radeon RX 6900 XT, followed by the RX 6800 XT and RX 6800; which are all based on the "Navi 21." These are followed by the RX 6700 XT and RX 6700, which are based on the "Navi 22" silicon.

The "Navi 21" silicon physically features 80 RDNA2 compute units, working out to 5,120 stream processors. The RX 6900 XT maxes the chip out, enabling all 80 CUs, and is internally referred to as the "Navi 21 XTX." Besides these, the RX 6900 XT features 16 GB of GDDR6 memory across a 256-bit wide memory interface, and engine clocks boosting beyond 2.30 GHz. The next SKU in AMD's product stack is the RX 6800 XT (Navi 21 XT), featuring 72 out of 80 CUs, working out to 4,608 stream processors, the same 16 GB 256-bit GDDR6 memory configuration as the flagship, while its engine clocks go up to 2.25 GHz.

AMD is preparing to launch its Radeon RX 6000 series of graphics cards codenamed "Big Navi", and it seems like we are getting more and more leaks about the upcoming cards. Set for October 28th launch, the Big Navi GPU is based on Navi 21 revision, which comes in two variants. Thanks to the sources over at Igor's Lab, Igor Wallossek has published a handful of information regarding the upcoming graphics cards release. More specifically, there are more details about the Total Graphics Power (TGP) of the cards and how it is used across the board (pun intended). To clarify, TDP (Thermal Design Power) is a measurement only used to the chip, or die of the GPU and how much thermal headroom it has, it doesn't measure the whole GPU power as there are more heat-producing components.

So the break down of the Navi 21 XT graphics card goes as follows: 235 Watts for the GPU alone, 20 Watts for Samsung's 16 Gbps GDDR6 memory, 35 Watts for voltage regulation (MOSFETs, Inductors, Caps), 15 Watts for Fans and other stuff, and 15 Watts that are used up by PCB and the losses found there. This puts the combined TGP to 320 Watts, showing just how much power is used by the non-GPU element. For custom OC AIB cards, the TGP is boosted to 355 Watts, as the GPU alone is using 270 Watts. When it comes to the Navi 21 XL GPU variant, the cards based on it are using 290 Watts of TGP, as the GPU sees a reduction to 203 Watts, and GDDR6 memory uses 17 Watts. The non-GPU components found on the board use the same amount of power.

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.
