It seems that finally there will be a small delay in the arrival of the Radeon RX 6950XT, 6750XT and 6650XTa refresh of the RX 6000 series that we initially expected for the 20th of this month, but that according to what we can read in Videocardz, would finally be delayed 20 days, until 10th May. And along with them, that same day, the Radeon RX 6400 would also debut on the market, thus offering the option of entering the series for individuals who wish to use it in their systems.
With this new batch of graphics cards, AMD stands up to the NVIDIA RTX 30 series catalog update, which is also adding new models these months. Thus, except for surprise, we can understand that we are witnessing the last movements of the current generation of graphics adapters, before the arrival of the expected RX 7000 and RTX 40 series, from AMD and NVIDIA respectively, and that they would remain with the Radeon RX 6950XT and the GeForce RTX 3090 Ti as top of the range.
If we review its specifications, we see that the Radeon RX 6950XT is supported by a 7 nanometer Navi 21 XTXH GPU, that is, the same chip found in the Radeon RX 6900 XT LC. In fact, both models also coincide in their 16 gigabytes of VRAM memory at 18 GB/s as well as in their 256-bit bus. The only difference, which indicates that the performance of the Radeon RX 6950XT could be a bit higher, is its TBP of 350 watts, 20 more than 6900 XT LC. This is what invites us to define the RX 6950XT as the top of the range of its generation.
Next we find the Radeon 6750XT, located in principle (in the absence of further details about it) in the upper-middle part of the table, since it would be located below the Radeon RX 6800 and above the Radeon RX 6700 XT, with which you probably will share GPU, the seven-nanometer Navi 22 XT. They would also coincide in the 12 gigabytes of VRAM and the 192-bit bus, but with the difference that in this new model the memory speed is 18 GB/s, compared to 16 in the previous model.
We expect its TBP to be higher than the 230 watts of the Radeon RX 6700 XT, and not only because of the higher memory speed, but also because its heat dissipation system now has three fans, compared to the two equipped by its predecessor.
Not leaving the middle of the table, but now at its bottom, we find the Radeon RX 6650XT, located just below the most basic model of the 67xx line, the Radeon RX 6700 XT, and just above the Radeon RX 6600XT. Here we see a situation similar to the previous case. Both 66xx share GPU, the Navi 23 XT, the amount of VRAM memory, 8 gigabytes, and the 128-bit bus. Differences? The memory speed, 18 Gb/S on the 6650 vs. 16 Gb/S on the 6600, and that would make the jump from one to two fans, so we can also expect a higher TBP.
As for the Radeon RX 6400, everything indicates that it will be the retail version of the Radeon RX 6400 (OEM), which, as you can deduce from its last name, has only been aimed at the PC assembler market, that is, end users have not had the possibility of acquiring it independently. We hope it will be based on the Navi 24XL GPU, which has 4 gigabytes of VRAM (the question is whether we will also see the jump from 16 to 18 Gb/s in this case) and a 64-bit bus.
In terms of design, it seems that these new Radeon RTX will adopt the design of the RX 6800XT Midnight Black Edition, an elegant black design
