Courtesy of Videocardz we now have the official specifications and performance numbers of the AMD Radeon RX 6600 Non-XT graphics card. They were able to get access to the reviewer’s guide before NDA which lists down the entire specifications along with performance comparisons against the 6600 XT and the RTX 3060.
As we know AMD’s Radeon RX 6600 Non-XT is the latest and most probably the last entry in the Radeon RX 6000 series family. It will replace the Radeon RX 5600 and will be powered by the RDNA 2 core architecture.
Coming to the specifications of the AMD Radeon RX 6600 graphics card, we know that it will feature the Navi 23 XL GPU that is going to feature 28 Compute Units or 1792 stream processors.
The card will also rock 32 MB Infinity Cache and will be supported by up to 8 GB GDDR6 memory capacity running across a 128-bit wide bus interface. The core clocks will be maintained at 2044 MHz game and 2491 MHz boost, but the 8 GB of memory might pose trouble as NVIDIA has just been reported to ditch 8 GB variants and focus on more powerful variants offering higher performance.
According to rumors, we can also expect the graphics cards to feature 30 MH/s in the Ethereum mining, and in terms of synthetic performance, the card scores 7805 points in the 3DMark Time Spy graphics test.
AMD Radeon RX 6600 series is a premium 1080p gaming solution hence the company will be launching the card for $379 US so we can expect a price of around $299-$329 US for the non-XT variant.

AMD RX 6600 Graphics Card Performance
when the performance of the AMD RX 6600 graphics card is compared against the AMD Radeon RX 6600 XT and the NVIDIA GeForce RTX 3060, it shows that the AMD Radeon RX 6600 is on par with the NVIDIA GeForce RTX 3060.
in terms of raytracing, however, AMD’s offering is 13% slower than the GeForce RTX 3060 and only manages a lead in F1 2021 which favors AMD cards. The system used featured the AMD Ryzen 5 5600X CPU with SAM enabled so performance results with Intel systems will vary a bit.
AMD is expected to launch its card on 13th October along with the official reviews so, let’s wait for some additional details in the coming week.
