AMD first announced the Radeon RX 6900 XT LC featuring a pre-binned Navi 21 XTXH GPU in June with the product only available to select system integrators and OEMs. These reference design cards were not expected to be available in the DIY market but listings for the cards appeared on some Indian retailers after the announcement. The card appears to be receiving a limited release with PowerColor's model (16GBD6-MW2DHC) now available to purchase from German retailer Mindfactory for 1749 EUR. The AMD Radeon RX 6900 XT LC features an increased boost clock speed of 2435 MHz from the 2250 MHz on the RX 6900 XT along with a memory speed boost from 16 Gbps to 18 Gbps.

AMD will be making a limited number of Radeon RX 6900 XT liquid cooled reference design graphics cards available to select system integrators. System integrators are a critical part of the gaming ecosystem and offering this this model through their channels helps ensure that as many of these products as possible get into gamers hands.

Graphics cards may be on their way to becoming unicorns that you can only pay for after finding the proverbial pot of gold from under a rainbow, but that doesn't mean AMD and NVIDIA will slow down their competition any time soon - especially in this market, there's a huge profit to be made. And AMD may just be finally readying their true halo product - a graphics card that aims to beat NVIDIA's RTX 3090 across the board. Twitter user CyberPunkCat shared an alleged AMD slide showcasing a new, overpowered RX 6900 XTX graphics card. AMD's naming scheme for their RX 6900 series may be slightly confusing nowadays: the original RX 6900 XT carries the Navi 21 XTX die, and AMD has recently released a higher-performance version of that Navi 21 chip in the form of the Navi 21 XTXH - which power the liquid-cooled versions of the RX 6900 XT, with higher overall clocks than the original GPU release. However, there hasn't been a change in the RX 6900 XT nomenclature - but this new slide suggests otherwise.

If the leaked slide is real (keep your NaCl ready, as always), it appears that the RX 6900 XTX might pair both the higher-performance Navi 21 XTXH chip with higher memory speeds. While both Navi 21 XT and Navi 21 XTXH both make use of 16 Gbps GDDR6 memory, the slide indicates that the RX 6900 XTX will feature 18 Gbps memory speeds, exploring another avenue for increased performance. This decision would bring an increase in maximum theoretical memory subsystem bandwidth from the 512 Gbps in the RX 6900 XT up to 576 Gbps - a 13% increase, which would not translate into a proportional increase in final performance. However, considering how our own reviews show that AMD's RX 6900 XT with the Navi 21 XTXH silicon is already between one and three percent faster than NVIDIA's RTX 3090, even a slight, 5% performance increase over that cards' performance means that AMD might be able to claim the performance crown for the mainstream market. It's been a while since that happened, hasn't it?

ASUS today updated its flagship AMD Radeon RX 6000 series graphics card lineup with the new ROG Strix LC Radeon RX 6900 XT TOP T16G. This card is visually identical to the ROG Strix LC RX 6900 XT O16G the company launched last December, but with a handful updates. The biggest of these is the new "Navi 21 XTXH" silicon, the highest bin of AMD's top RDNA2 chip, which enables at least 10% higher clock-speeds than the standard RX 6900 XT. ASUS has tuned this up further, with a max boost frequency of a stunning 2525 MHz, compared to 2365 MHz on the original (O16G). The game clocks have been increased to 2375 MHz, compared to 2135 MHz on the O16G. Notice how the game clocks of the new T16G are higher than the max boost clocks of the original O16G? That's the magic of the new XTXH silicon.

These apart, the company hasn't made any changes to the visual design. A liquid+air hybrid cooling solution dominates the product. The AIO liquid closed-loop cooling solution pulls heat from the GPU and surrounding memory chips, while a base-plate and a chunky back-plate pull heat from the other components, which is ventilated by a lateral blower. The AIO is cooled by a 240 mm x 120 mm radiator. The card continues to pull power from a combination of three 8-pin PCIe power connectors. The company didn't reveal pricing, but it's very likely to be close to 2 grand.

TechPowerUp today released the latest version of TechPowerUp GPU-Z, the tiny-yet-mighty software that gives you information, monitoring, and diagnostics of your PC graphics subsystem. Version 2.39.0 adds support for the Gen12 Xe LP integrated graphics solution found with Intel 11th Gen Core "Rocket Lake" processors. GPU-Z also has the ability to tell the new "Navi 21 XTXH" Radeon RX 6900 XT variant, from the standard RX 6900 XT. Support is also added for NVIDIA RTX 3060 Mobile, RTX 3050 Ti Mobile, RTX 3050 Mobile, RTX A5000, T500, CMP 30HX, CMP 40HX, CMP 90HX; and AMD Radeon Pro W5500M, and Barco MXRT 4700.

Version 2.39.0 also improves in several areas. The integrated screenshot feature is refreshed to better capture the window area. The XML dump is made more usable, with information that includes BIOS UEFI support, WHQL status, Driver Date, DXR, DirectML, OpenGL and Resizable BAR. The video memory utilization sensor is disabled on TCC mode-enabled NVIDIA GPUs. A number of minor issues were also fixed, related to Resizable BAR detection, clock readings on AMD RDNA2 mobile GPUs, a bug with OpenGL detection on certain systems, memory clock readings on certain legacy GPUs, BIOS date readings on legacy GPUs, etc. Grab it from the link below.

AMD is in constant progress with its Radeon graphics card lineup and the company is always working on new models that will better suit the market. Today, we have interesting discovery. On Weibo, a Chinese microblogging website, a user has posted pictures of what appears to be an engineering sample of AMD's Radeon RX 6900 XTX graphics card variant. Having an all-in-one (AIO) water-cooled design with a 120 mm radiator, the card resembles a power-hungry design as we have seen with Radeon R9 Fury X and RX Vega 64 Liquid Edition, which were both graphics cards equipped with AIO water cooling. This engineering sample is no different.

Under the waterblock, there is a Navi 21 XTXH GPU SKU hidden. As we found out, this is a new Navi 21 XTX SKU that just features better binning compared to Navi 21 XTX, and thus it offers better overclocking potential. It is already present in three new models from various AIBs, like the PowerColor RX 6900 XT Liquid Devil Ultimate, ASRock RX 6900 XT OC Formula, and Sapphire RX 6900 XT Toxic Extreme graphics cards. It seems like AMD has prepared itself to launch this specific SKU in a reference design form, however, so far only AIBs have used the Navi 21 XTXH SKU. It is not yet clear if the Radeon RX 6900 XTX is ever going to hit the retail market, or it shall remain as it is - just an engineering sample.

Overclocker extraordinnaire Roman "der8auer" Hartung has achieved a new world record for GPU clockspeed with the help of exotic cooling and PowerColor's RX 6900 XT Liquid Devil Ultimate. The PowerColor Red Devil Ultimate features the latest and greatest bin of any RX 6900 XT chip, featuring AMD's Navi 21 XTXH silicon (device ID 0x73AF), with improved clockspeed potential and lower leakage than the usual XT cadre of chips. Using LN2 cooling which dropped the operating temperatures of the card down to a finger-killing -87 °C, the overclocker managed to reach a 3,225 MHz clock - as reported by our very own GPU-Z, which continues to be the diagnostics tool of choice for graphics cards. Look after the break for the full video leading up to this overclocking feat.

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.
