AMD Radeon RX 6600 (XT), specifications of this gaming GPU

AMD released its next-generation graphics cards months after NVIDIA, which is why their launch cadence does not keep up. If a few months ago NVIDIA showed us the RTX 3060 as a low-mid-range GPU, now it is the turn of its rivals, the AMD Radeon RX 6600 XT and RX 6600 from which its characteristics have already been leaked.

The RX 6600 from AMD will compete head-to-head with the RTX 3060 from NVIDIA, although with months of delay, it is also expected that these will be the basis for the RX 6000 Mobile range that will also appear in the following weeks.

AMD RX 6600 (XT) Specifications

Both designs are based on the Navi 23 GPU, which, like the rest of the GPUs in the range, is based on the RDNA 2 architecture and has, like these, all its functionalities such as Ray Tracing, Variable Rate Shading and the integration of the Infinity Cache. Although all this with a simpler configuration than the Navi 22, RX 6700 XT, and Navi 21, RX 6800 (XT) and RX 6900 XT GPUs.

Both the RX 6600 and RX 6600 XT use a 128-bit GDDR6 configuration with 8 GB capacity. Continuing AMD’s tradition with its RX 6000 of making use of 2GB memory chips for its GPUs. However, despite being the same chip, we find two different configurations:

  • The RX 6600 XT dispose of 2048 Stream Processors, which is what AMD calls the 32-bit ALUs in Compute Units. Its equivalent to CUDA cores. Taking into account that the mean per CU in RDNA 2 is 64 this makes 32 Compute Units in total.
  • The RX 6600 instead it has some Compute Units disabled, its configuration being 1796 Stream Processors and therefore of 28 Compute Units in total.

As for the Infinity Cache, its density has been reduced by memory controller, this being 32 MB instead of the 64 MB if we scale of its older sisters. On the other hand, at the moment we do not know the clock speed of both GPUs, both in base and in Boost.

What is its performance?

RX 6600

It’s too early to tell, especially given the fact that the few benchmarks that have been made have been sourced from pre-mass production units of these graphics cards. However, it helps us to have an approximate idea where AMD can place both cards in terms of price and therefore the segment to which they will be directed.

On the benchmark TimeSpy the RX 6600 XT gets a result of 9439 points, a result very similar to that of its rival, the NVIDIA RTX 3060, which has the advantage of having 12 GB of VRAM. So AMD could be priced at a similar price to its direct rival, but lower due to the lesser amount of memory built into the graphics card. Instead the RX 6600 gets only 7805 points in the same performance test.

NVIDIA will launch at the same time the revision of its entire limited RTX 30 range for mining, while it is AMD’s policy not to limit it. 30 MH / s from RX 6600 XT it is little compared to the highest range, but it is more than the 20 MH / s that a limited RTX 3060 would get. The key question is whether the AMD RX 6600 (XT) are not going to be released only on paper.
