AMD Radeon RX 6950XT features Navi 21 KXTX GPU, supports Hynix and Samsung 18Gbps memory
AMD RX 6950XT graphics card will ship with Navi 21 KXTX GPU, as revealed by the leaked BIOS.
Chiphell community was quick to find BIOSes in TechPowerUP database. Although they were already removed, they confirm high TGP ranges for RX 6950XT SKU, their power limits and what memory they support.
Two of the cards listed there were MSI RX 6950XT GAMING X TRIO and SAPPHIRE RX 6950XT NITRO+ Pure. Although the latter has power limit set to 325W it can further be adjusted by 20%, which means as much as 390W of power. The power limit for MSI card is 332W and up to +12% increase, which is 372W. Do note that those are TGP (GPU+memory), not TBP. This means that full graphics card power will easily be beyond 400W.

The RX 6950XT model will ship with Navi 21 KXTX GPU, not XTXH as previously rumored. This means that AMD now has a fourth variant of Navi 21 GPU for its consumer Radeon series. Although, this is just a codename that could ‘theoretically’ be flashed over XT or XTXH variants.
However, there is a reason why one should not do it. The BIOS only supports 18 Gbps memory from HYNIX and Samsung. The latter appears to be the same variant as RX 6500XT memory uses (designated as HC18).

AMD Radeon RX 6000 Navi 21 XT & Navi 21 XL «Big Navi» GPU Clocks Speeds Reportedly Up To 2.4 & 2.2 GHz
In a series of tweets, veteran tech leaker, Rogame, has uncovered the clock speeds of AMD’s Navi 21 «Big Navi» GPUs which go on to power the top of the line Radeon RX 6000 series graphics cards. As per Rog Game, the Navi 21 XT and Navi 21 XL will have clock speeds up to 2.
4 GHz which is also something that was reported yesterday.
AMD Radeon RX 6000 Graphics Cards With Navi 21 «Big Navi» GPUs To Feature Up To 2.2-2.4 GHz Clock Speeds
The AMD Navi 21 GPU which is going to be the «Big Navi» chip will have several variants. We know from previous leaks that the Navi 21 SKU lineup includes the Navi 21 XTX, Navi 21 XT, Navi 21 XL & Navi 21 XLE. The graphics card that AMD teased at its Zen 3 announcement was most likely based on the Navi 21 XT die and will be referred to as the Radeon RX 6900 XT. Yesterday, it was reported that the Navi 21 XT GPU will feature insane clocks of 2.4 GHz and a TGP of 255W. Rogame gives us an even better insight on what to expect from Navi 21 SKUs in regards to their clock frequencies.
[Update Navi21] 🧐

The leaker reports that both Navi 21 XT and Navi 21 XL «Big Navi» GPUs for Radeon RX 6000 series graphics cards will feature a huge variation between the base and boost clocks. We’re looking at up to a +700 MHz difference between the base and boost frequencies. Following are the clock speeds as listed by Rogame:
AMD Radeon RX 6000 Series Navi 21 XT «Big Navi» GPU Clocks (via Rogame)
- Base clock 1450MHz to 1500MHz
- Game clock 2000MHz to 2100MHz
- Boost clock 2200MHz to 2400MHz
AMD Radeon RX 6000 Series Navi 21 XL «Big Navi» GPU Clocks (via Rogame)
- Base clock 1350MHz to 1400MHz
- Game clock 1800MHz to 1900MHz
- Boost clock 2100MHz (maybe 2200MHz)
According to the leaker, the Navi 21 XT/XL GPUs will feature even higher clock speeds in AIB made custom models. The first batch of GPUs will be sold as reference only variants but AMD’s partners are definitely cooking their own custom designs that will feature even higher clock speeds.
Similar statements were provided by Videocardz whose sources at AIBs reveal that the Navi 21 XL will have peak clock speeds around 2.2 GHz, similar to what’s stated by Rogame. It is likely that the red team will artificially lock the clock speeds but reference samples are said to feature around 2.3 GHz peak clocks with AIB models hitting the 2.4 GHz clocks out of the box.
As per Rogame, the Navi 21 GPU currently has the following SKUs:
- Navi 21 XTX (0x731F:D0)
- Navi 21 XT (0x731F:D1)
- Navi 21 XL (0x731F:D3)
- Navi 21 XLE (0x731F:DF)
The AMD Navi 21 XTX and XLE variants are currently unknown and the former is said to be an AMD exclusive variant. There are rumors that the Navi 21 XTX can feature a higher number of cores than the Navi 21 XT GPU which peaks out at 5120 stream processors or 80 CUs (Compute Units) but that remains to be seen. The XTX variant could be a special binned variant that AMD can market as the highest performing Big Navi Radeon RX 6000 series graphics card.
Previously, the highest-end SKUs have received more premium designs such as AIO coolings and we can see a return of that on the XTX variant.
— Max. TGP of Navi 21 XT is 290 W.
— AIB partners are testing different TGP for their cards.
— The ~2.4 GHz was achieved with an AIB partner card. So assume that the card was slightly overclocked.— Patrick Schur (@patrickschur_) October 18, 2020
Patrick Schur has also reported that while the 255W TGP is mostly close to the reference spec, the max TGP is suggested around 290W. AIB models will feature different TGP’s based on their cooling and board designs. Patrick also reaffirms that the 2.4 GHz Game clock was achieved by an AIB card so it could’ve been slightly overclocked outside its factory overclocked specs.
As for the Navi 21 XT and XL graphics card, these cards are said to feature 16 GB and 12 GB GDDR6 memory capacities. The bus interface for the 16 GB variant is 256-bit as per the leaked PCB but can change in the final variant.
There are also reports of Infinity Cache being one of the big features on Navi 21 GPUs, offering higher bandwidth figures to boost high-res gaming performance. These are the specifications that we know so far but expect more leaks to occur in the coming days prior to the unveiling itself.

AMD Radeon RX 6900 Series With Triple-Slot Cooling Solution:
As for the designs themselves, the Radeon RX 6000 flagship cooling design looks amazing with the red and black design. The card features a triple axial-tech fan setup on the shroud and has a large aluminum heatsink that runs beneath it. The card has a LED-lit Radeon logo on the side and there is a large cut out on the side for the fans to vent out hot air.
This design is very reminiscent of the NVIDIA GeForce RTX 20 series Founders Edition cooler. The card will feature dual 8-pin power and display ports would include a USB Type-C (VirtualLink), 1 HDMI, and 2 DisplayPort connectors.
The card also features a fancy backplate along with a retention bracket to hold the cooler in place. The Radeon RX «Big Navi» GPU looks like it will come in the standard 2-slot reference design which is the same as NVIDIA’s flagship RTX 3080 but not as huge as the triple-slot GeForce RTX 3090.
AMD will officially be unveiling its Radeon RX 6000 series graphics card family on October 28th. The second half of 2020 would definitely be interesting times for all the hardware enthusiasts and mainstream PC gamers who are looking forward to upgrading their PCs with the best hardware.

More about the course
Recent data indicates that the Navi 21 GPU will be the basis for at least three Radeon RX 6000 series graphics cards. The Navi 21 XT variant will be used in the flagship Radeon RX 6900 XT, codenamed Big Navi. Along with the Navi 21 XT, there is also a selected exclusive version of the Navi 21 XTX, designed for the potential Radeon RX 6900 XT Limited Edition (similar to the Radeon RX 5700 XT 50 th Anniversary for the higher segment), as well as a stripped down version of the Navi 21 XL.
All three cards based on Navi 21 GPUs will receive 16 GB of 256-bit GDDR6 video memory, complemented by special Infinity Cache caching technology, which should provide memory bandwidth parity with competing RTX 3080/3090 models, using faster GDDR6X memory.
New data indicates that the base Navi 21 XT GPU in non-reference cards from AMD’s AIB partners will be able to overclock to an impressive 2.4 GHz in Game Clock mode — no other GPU on the market today can boast such a high operating frequency. The TGP (total graphics power) is expected to be 255W. That is, the TBP (total board power) value should be at the level of the GeForce RTX 3080 (~ 320 W). At the same time, the peak frequency of the GPU Radeon RX 6900 XT in the reference version will be limited to 2300 MHz.
It is not entirely clear what these impressive operating frequencies will mean in practice. Judging by the official Radeon RX 6900 XT performance benchmarks that AMD shared during the recent Ryzen 5000 announcement, the new Reds flagship will definitely be faster than the RTX 3070, but will it be able to compete with the RTX 3080? This question still remains unanswered.
The full announcement of the RX 6000 series of graphics cards, which will compete with the latest NVIDIA GeForce RTX 30-series adapters, will be held on October 28th.
