The wait for the hugely anticipated NAVI 23 graphics cards is almost over, with the latest rumours from Fudzilla suggesting that the RX 6600 XT and RX 6600 could both launch this August 11th. The new RDNA 2 GPUs will be aimed at the mainstream gaming audience and should boast excellent performance in 1080p and 1440p gaming scenarios.
Like always, AIBs will be releasing a whole host of reference models that will likely span the usual suspects from all the major players. Both Radeon RX 6600 XT and RX 6600 will be the first 6000 series desktop cards to feature the latest NAVI 23 technology – with PRO and mobility variants already featuring the tech.
AMD Radeon RX 6600 XT Specifications
AMD’s new Radeon RX 6600 XT will feature the NAVI 23 XT GPU which will feature 32 compute units or 2048 stream processors. Alongside this, it will also offer up 32 MB Infinity cache, 8GB of GDDR6 VRAM, and a 128-bit bus interface.
The GPU itself will measure in at 237mm2 and will consist of 11.06 billion transistors, making it one of the smallest chips in the range – with the Navi 24 being the smallest. Users can expect a total bandwidth of 256 GB/s and pin speeds to remain at 16 Gbps. As far as performance goes, early signs suggest that the card will be expected to feature 30 MH/s in Ethereum mining and score highly in synthetic benchmarks such as 3DMark Time spy (9439 points).
AMD Radeon RX 6600 Specifications
Like all XT and non-XT variants, the RX 6600 will be the weaker of the two cards. It will feature the Navi 23 XL GPU, equipped with 28 compute units or 1792 stream processor, 32MB of Infinity Cache, 8GB GDDR6 VRAM, and a 128-bit bus interface.
Like the RX 6600 XT, the pin speeds of the 6600 will also be kept at 16 Gbps for a total bandwidth of 256 GB/s. Comparing the Navi 23 XL to the XT, users can expect a 10% dip in Ethereum mining (27 MH/s) and closer to a 20% reduction in synthetic benchmarks like 3DMark Time Spy (7805 points).

Pricing And Release Dates
So, as we said earlier, both cards are rumoured to release on the 11th of August 2021, meaning gamers should be able to get their hands on one of these standout GPUs in just over 3 weeks time. However, pricing and availability is still very much a grey area.
Some rumours have suggested that the RX 6600 XT will retail for roughly $399 US, making it a premium 1080p solution and putting it on par with the GeForce GTX 1080 Ti – a GPU that is still incredibly versatile in today’s market.
Whilst the RX 6700 XT is tailored more towards the 1440p market, the same can not be said for the RX 6600 XT – with its sights set more clearly on 1080p gaming or, at best, entry-level 1440p. Having said that, with the recent arrival of FSR – and the clear advantages it brings – we wouldn’t be surprised to see some impressive results when using a 6600 XT in this particular format.
In comparison, the RX 6600 looks set to be the ‘premium’ 1080p gaming GPU for the 6000 series lineup, with expected pricing to be closer to $300 – albeit still completely unknown.
For as long as he can remember, Charlie has always been interested in computers and gaming. It all started with the Sega Mega Drive and then evolved into PC gaming in his early teens. CS 1.6 was his first go at competitive gaming which soon evolved into CS:Source and now CS:GO - a game that he still plays (almost exclusively) today. Throughout that period he has also been a keen PC builder and enthusiast - dedicating a large portion of his time to the craft. My current rig is an ASUS 5700XT with AMD's Ryzen 3600X.
