Radeon RX 6600 is built on GPU Navi 23. This is the same basis as the Radeon RX 6600 XT, compared to which differs by a reduced number of stream processors (2048-> 1792) and texturing units (128-> 112), the bars also decreased, although the maximum did not change significantly, only by 98 MHz . What remained the same for both models is the number of ROP units (64), Infinity Cache capacity (32 MB), bus width (128bit) and memory capacity (8 MB).

But I have to stop briefly at the memory frequency. I listed 14 GHz in our spreadsheet, but in an October 6 article, I was convinced by VideoCardz, which pretended to have final specifications, and presented 16 GHz. In the end, it is not correct and the reference clock speed is 14 GHz (which, however, does not prevent manufacturers of OC models from installing better 16 GHz modules).
In terms of performance, the Radeon RX 6600 performs slightly better than various estimates (which put it at 94-96% GeForce RTX 3060. In the end, it achieves 98% of its performance and 87% of the performance of the Radeon RX 6600 XT.
Consumption is nothing to complain about. When a GPU of 237 mm² (which is a higher area than, for example, a 175W Radeon HD 7870 “GHz Edition”) at an average clock speed of 2509 MHz and a maximum clock speed of 2623 MHz does not exceed 135 watts, it is objectively difficult to criticize anything. Real consumption is exactly 38 watts lower than the GeForce RTX 3060, which surprisingly corresponds exactly to the difference in paper TDP (170-132 = 38 watts).
In terms of energy efficiency, the Radeon RX 6600 is placed exactly between the Radeon RX 6600 XT and the Radeon RX 6700 XT.
AMD has set the official price at $ 329, which is the same value as the official GeForce RTX 3060 price. GeForce RTX 3060, but significantly more economical, should be cheaper. However, this is unnecessary because – as sales of the Radeon RX 6600 XT have shown, despite the higher recommended price, the card was cheaper than the GeForce RTX 3060 at real stock availability. cen.
