AMD seems to be working on a graphics card based on the new Big Navi 21 silicon that would bring the Radeon RX 6900 XTX to life. According to the leaked rumor, this new graphics card will have more VRAM memory and higher frequencies.
AMD could be developing a new Radeon RX 6900 XTX graphics card with higher frequencies and VRAM
The RX 6900 XT graphics cards are currently based on Navi 21 XT silicon and a Navi 21 XTXH variant. Both types of silicon animate the same graphics card without any difference in parameters. Now, it seems that AMD is working on a third RX 6900 XT graphics card that will be based on Navi 21 XTXH silicon. This new graphics card will have higher clock speeds and more VRAM. According to rumors, this hypothetical RX 6900 XTX would be superior to the NVIDIA RTX 3090.
We know this thanks to an alleged image of a slide leaked by CyberPunkCat. Who also points out that this new graphics card would have almost 25 TFLOPS of performance. The RX 6900 XT graphics card currently delivers up to 23 TFLOPS at boost frequency. Moreover, it is rumored that the boost frequency could be increased from 2250 MHz to 2435 MHz, which is an 8% improvement.
According to the rumors, this new graphics card will keep the 16 GB GDDR6, but there will be changes in frequency and bandwidth. This new memory would operate at 18 Gbit/s instead of 16 Gbit/s like the current memory. The bandwidth has also been increased to 576 GB/s, which is a 12.5% increase.
All these improvements will have a direct impact on the price, which is not known at this point. A change in power consumption is also highlighted, as we would go from a TBP of 300W for the RX 6900 XT to a TBP of 350W for the hypothetical RX 6900 XTX.
As we can see, this graphics card, when it hits the market, will be aimed at the high end of the range. It won’t be a graphics card focused on the entry-level or mid-range segment, where AMD is already well-positioned. Perhaps the biggest drawback to this solution is the current inventory issues.
There are rumors that this Navi 21 XTXH-based graphics card could be destined for the OEM segment. This seems unlikely since OEM solutions are usually “simpler” than mainstream versions. So, launching a graphics card for the OEM segment that is more powerful than the cards already on the market seems to make little sense.
The RX 6900 XT LC based on the Navi 21 XTXH is currently on the market. This graphics card features slightly higher frequencies than the reference model and has an all-in-one liquid cooling system.
Again, this is a rumor that should be taken with a grain of salt. It could well be that someone did a montage at home to generate hype. We will wait for the developments and the official presentation if this graphics card really exists.
