AMD took a leaf from Intel’s playbook with its Radeon RX 6000 mobile benchmark comparisons. Turns out that the company compared its Radeon RX 6800M that has a TGP of 150W (+15W dynamic) against a GeForce RTX 3080 laptop wherein the latter has a base TGP of 115W, with an additional 15W upon boosting. Similarly, the Radeon RX 6600M with a TGP of 100W was compared with an RTX 3060 with a base TGP of 90W and a dynamic boost draw of 95W.
Although the delta in the case of the second one isn’t notable, the former is a cause for concern. If vendors continue to compare their latest products to rival offerings with lower TDP targets, it’ll make determining the power draw and resulting performance even harder in the mobile segment (than it already is).
During its Computex 2021 keynote earlier today, AMD announced its Radeon RX 6000 mobile GPU lineup which includes the RX 6600M, 6700M, and 6800M. The 6600M is targeted at 1080p gaming with 28 CUs, 32MB of L3 (Infinity Cache), and 8GB of GDDR6 memory. It’s based on the Navi 23 die. The Radeon RX 6700M and 6800M leverage the Navi 22 die with 36 and 40 CUs, respectively. The former includes 10GB of GDDR6 memory and the latter packs slightly more with 12GB of GDDR6 VRAM. Finally, in terms of the Infinity Cache, the 6800M features 96MB of L3 cache (same as the 6700 XT) while the 6700M cuts it down to 80MB. Both feature a 192-bit bus, with the 6600M being limited to 128-bit.
