The RX 6600M GPU is a graphics card that is part of the 6000M series of laptop-only AMD GPUs (the ‘M’ standing for Mobility). This particular entry is the first graphics card to be released that makes use of the Navi 23 GPU, and has been billed by AMD as a direct competitor to Nvidia’s RTX 3060 (mobile version).
Let’s see what this independent benchmark from Zhuanlan, the first to hit the internet, has to say about whether this is a serious claim or not.
RX 6600M Specifications
Specs for the RX 6600M graphics card, as tested by Zhuanlan can be seen above in the screenshot they took from GPU-Z when testing the GPU.
As you can see the RX 6600M comes with 8 GB (or 8,192 MB) GDDR6 VRAM and a 128-bit memory bus, with a boost clock of 2448 MHz. The card has 1792 stream processors (designated as ‘shaders’ above) which translates to 28 compute units.
Not shown is the 100W TGP that these cards also have, which is lower than the 115W of the RTX 3060.
AMD Radeon RX 6600M Benchmarks
According to Zhuanlan the above benchmarks were tested on a laptop with an AMD Ryzen 7 5800H CPU and 16 GB of DDR4-3200 RAM for all of the graphics cards.
As you can see above, whilst the RX 6600M pulls ahead on the odd title, like CS:GO, in most titles, it was a few frames behind at 1080p compared to the RTX 3060 laptop version, which averaged a lead of around 8%. Unsurprisingly on titles where Ray-Tracing was turned on the RTX 3060 performed substantially better, with FPS up to 36% higher on the tested titles.
We have not yet had chance to verify these figures ourselves, and won’t until we get our own hands on a copy of the RX 6600M to test, but if they are to be believed then these results seem to contradict AMD’s own figures which put their mobile GPU ahead. The fact that the RX 6600M fails to outperform even on a laptop with an AMD Ryzen 5000-series CPU is particularly disappointing.
The above results show a mobile GPU which gives respectable performance, just below that of the Nvidia killing card we were promised. Still, it may be that driver updates in the future unlock additional potential from the RX 6600M vs the RTX 3060. We will just have to wait and see what future benchmarking from other testers brings.
Besides this the other consideration is of course price: if AMD prices the RX 6600M between the RTX 3050 Ti and the RTX 3060 then it could be the AMD mobile graphics card proves to be a competitive option, seeing as it comfortably beats the 3050 Ti in all the above tests, sometimes trouncing it.
