AMD Radeon RX 6600 Non-XT ‘Navi 23’ Launches In Late Q3, Navi 24 ‘Beige Goby’ By End of 2021

AMD's second Navi 23 GPU-powered graphics card, the Radeon RX 6600, won't see a launch until late Q3 2021. The information comes from Coreteks just a day after it was reported that the AMD Radeon RX 6600 series cards might launch simultaneously on the 11th of August.

The AMD Radeon RX 6600 series would include two variants, the RX 6600 XT & the RX 6600. The Radeon RX 6600 XT is going to feature the Navi 23 'Dimgrey Cavefish' XT/XTX SKU while the AMD Radeon RX 6600 will feature the Navi 23 XL SKU. While these cards were reported to be launching at the same date, now it looks like the launch will take place at least a month apart.

Coreteks reports that the AMD Radeon RX 6600 (Non-XT) would launch in late Q3 2021 or early Q4. So the earliest we can see this graphics card in the market would be September which is a month apart from August when the RX 6600 XT launches. There's also a potential announcement that is expected next week though we can't say for sure if the RX 6600 series will be a part of it or if both cards would be announced considering the non-XT variant of the RX 6700 series is yet to make an appearance.

AMD Radeon RX 6600 Graphics Card Specifications:

The AMD Radeon RX 6600 graphics card is expected to feature the Navi 23 XL GPU which is going to feature 28 Compute Units or 1792 stream processors. The card will also rock 32 MB Infinity Cache & will feature up to 8 GB GDDR6 memory capacity running across a 128-bit wide bus interface.

The pin speeds will be kept at 16 Gbps which will bring the total bandwidth to 256 GB/s. As per the rumor mill, the graphics card is expected to feature 27 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 (referring to the RX 6600 XT) will be positioned as a premium 1080p gaming solution. Recent rumors have stated pricing of $399 US for the Radeon RX 6600 XT 8 GB variant and put its performance on par with the GeForce GTX 1080 Ti though that's pretty steep pricing for what is to be a 1080p graphics card since it would offer the same performance as an RX 5700 XT for pretty much the same price with lower power draw being the only advantage over its RDNA 1 predecessor. The Radeon RX 6600 could end up around $299 US but that remains to be seen.

AMD Radeon RX 6000 Navi 24 'Beige Goby' GPUs

It is also reported that AMD's most entry-level RDNA 2 GPU for the desktop segment, the Navi 24 'Beige Goby' will be launching by the end of 2021. The Navi 24 RDNA 2 GPU will feature a single SDMA engine. The chip will feature 2 shader arrays for a total of 8 WGPs and a maximum of 16 Compute Units.

AMD has 64 stream processors per compute unit so that brings the total core count on the Navi 24 GPU at 1024 which is half that of the Navi 23 GPU which will offer 2048 stream processors in 32 compute units. In addition to the number of cores, each shader array would feature 128 KB of L1 cache, 1 MB of L2 cache and there would also be 16 MB of Infinity Cache (LLC).
