In the case of power requirements, AMD lists this GPU at up to 100W, although every laptop using it so far is a SmartShift design where the total power capabilities of the system are shared between the CPU and GPU. There's also 32MB of Infinity Cache on the GPU itself. It is, however, clocked relatively high for a mobile part, with a "game clock" of 2177 MHz - that's the frequency AMD expects the GPU to run at in games at the highest power level and a little higher than the RX 6600 desktop card.Īs for the memory subsystem, AMD is including 8 GB of GDDR6 running at 14 Gbps over a 128-bit bus, delivering up to 224 GB/s of memory bandwidth. The full version of Navi 23 is used exclusively for the RX 6600 XT desktop GPU, so the 6600M is a cut down version. For the RX 6600M that we're looking at today, we've found at least a few choices from different vendors.ĪMD is using the same die configuration for the 6600M as the RX 6600 on the desktop, in that we're getting 28 compute units for a total of 1792 stream processors. As far as we're aware the 6800M is only used in the Asus ROG Strix line, and the 6700M is found in the MSI Delta, and that's about it. It's not easy to find these GPUs on the market, especially the Navi 22 designs. The Radeon RX 6600M is part of AMD's RX 6000 mobile series, which comprises only three GPUs: the 6800M and 6700M - which use AMD's Navi 22 die that we've also seen in the desktop RX 6700XT - and the 6600M, which uses Navi 23. Months ago we checked out the RX 6800M, AMD's top discrete graphics option for laptop gaming, but it's been a bit harder to find the RX 6600M for us to test until now, so better late than never. Today we're finally getting around to review another of AMD's latest generation mobile GPUs, the Radeon RX 6600M.
