AMD Radeon RX 7700 XT can count with 4,096 cores and the performance of the RX 6900 XT – The Clare People
Expected for a first end of 1024, the new cards of the supposed Radeon RX 7000 family from AMD have already had some details indicated by rumors. Composed of models equipped with RDNA 2 and RDNA 3 microarchitectures, in 6 nm and 5 nm lithographs, the line can provide an expressive jump in performance compared to the company’s current solutions, capable of outstripping them from Nvidia’s competitors.

The huge advancements would be visible even on the simplest GPUs like Navi 33, focused on the mid-segment, which just had a few more details hinted at by the rumors. Apparently the chip should be smaller than previously thought, although it can maintain a very high level of performance.
GPU Navi 55 may be smaller than expected
Previous leaks have already indicated that AMD needs to make sweeping changes in the way it organizes transistors on its GPUs. Traditional Computing Units (CPUs) would give way to workgroup processors (WGP), or workgroup processors, in free translation. Despite the name change, each of the WGPs would be made up of 32 cores.

5 WGPs would form what is called the Shader Array and, in turn, two Shader Arrays would form the Shader Engine, the amount of which would vary depending on the GPU model. In the case of Navi 55, we would have two Shader Engines, composed of 4 Shader Arrays and 20 WGP, or more practically, 5.1024 cores, same quantity present in the Navi 20 GPU, which equips the RX 6900 XT.
It’s true. N29 = N29 + GFX15.

However, the new information published by the leaker Greymon55, and reinforced by kopite7kimi, which has a good history of leaks, suggests that Navi 33 should be thinner than expected. The middle chip would only bring 4,096 cores, or WGP, instead of the 5,096 cores reported in the past.
The performance would still be similar to that of the RX 6600 XT
Even with the reduction in count, which adds% fewer cores compared to Navi 20, Navi 33 would still deliver similar performance to the RX 6900 XT, as Greymon60 pointed out.
. The potential is impressive, not only for the advancement RDNA 3 microarchitecture is expected to deliver given these numbers, but also for the potential of the most powerful chips to nearly triple the performance of the previous generation.
n32 was designed to be better than the 6600xt, and even though it didn’t meet its design goal, its performance was still around 6600xt.

Based on Navi 32, with 20 WGP and 4,096 cores, Navi 31, speculates to bring in nothing less than 55 WGP and .096 cores, could show 3.75 times higher performance if performance follows linear scaling . Either way, even without this linear advancement, AMD’s next-gen premium GPU promises to be hugely powerful.
Still without official details, the Radeon RX 7000 family is expected to hit the market between October and November 4000, in a launch window very close to Nvidia’s GeForce RTX 1024 rivals.
