amd will present today RadeonRX7000its next generation of dedicated graphics based on the RDNA 3 architecture. The company has worked hard to avoid leaks, but for a few days it seems that things are beginning to be known.
In the absence of whether or not what we are going to expose next becomes a reality, everything indicates that AMD could present three high-end oriented graphics cards tonight: RX 7800 XT, RX 7900 XT and RX 7900 XTX. The first two would be based on the Navi 31 die, while the third would use Navi 32. Even so, they will all be RDNA 3, and seeing the difficulties that Radeon is having to stand up to NVIDIA, the red giant does not have left another to put all the meat on the grill.
The RX7800 It would be the most “modest” graphic of the three that would be presented, but that does not mean that it will not be very good for any gaming and desktop context. In addition to the use of the Navi 32 die, it will have 30 workgroup processors (WGP) or 60 compute units (CU) that derive in 7,680 shaders. As for the amount of VRAM, this would be composed of 16GB at 20Gbps or 18Gbps in GDDR6 format and with a total bandwidth of 640GB/s or 576GB/s respectively. As for infinite cache, its amount would be 64MB.
We raise the bar to reach the RX7900XT, a model that has allegedly been castrated at the last minute to make room for its XTX variant. This graph aims to incorporate 40WGP or 80CU to add a total of 10,752 shaders. I would have 20GB of GDDR6 VRAM and a 320-bit bus versus the 24GB and 384-bit originally expected. The bandwidth would be 800GB/s (for 20Gbps) or 720GB/s (for 18Gbps), which would add up to 80MB of infinite cache memory compared to the 96 originally expected.
Navi 31, the die of RX 7900 XT and RX 7900 XTX.
And finally there is the RX7900XTX, which would be what was originally going to be the standard RX 7900 XT. This model would include 24GB of 20Gbps GDDR6 VRAM with a 384-bit bus and a bandwidth of 960GB/s. It is not ruled out that AMD will ultimately use 18Gbps memory and 864GB/s bandwidth, which is slower but more abundant and is already implemented in the RX 6950 XT, 6750XT and 6650 XT models.
Let’s see what AMD teaches at the moment of truth, more seeing the contradictory information that has been around RX 7000, since it was first said that it would not be a rival for NVIDIA’s RTX 40 generation, but then it was disclosed that the The team responsible for Radeon did have material to offer something up to par. Whatever happens, it is almost certain that AMD will avoid the use, at least for now, of adapters that can lead to partially unexpected results.
Finally, it is worth mentioning that Angstronomics has leaked a modified image of Navi 31 and the chiplets it uses. This is not a detail that matters much to most consumers, but it is something that has been able to see the light before the official presentation, whose transmission video we leave you below.
