[FPS Benchmarks] DOOM Eternal on AMD Radeon RX 6800M and RX 6600M – the bigger GPU is only 10% faster on average

DOOM Eternal is the successor of the 2016 version of DOOM which was a great reboot for the super-popular series. The new game brings great graphics to the table alongside dynamic gameplay and tons of weapons. There are new and more terrifying enemies (and bosses) that makes the gameplay more intense than ever.

Luckily, the game is decently optimized and it can run on low-end dGPUs and iGPUs like NVIDIA GeForce MX350 (25W) or AMD Radeon RX Vega 7 (Ryzen 4000) Forthisaricle, we’ll compare two fast AMD GPUs – the Radeon RX 6800M and RX 6600M.

Gaming tests and gameplay videos (ext. monitor)

Doom Eternal Full HD, Low (Check settings) Full HD, Medium (Check settings) Full HD, U.Nightmare (Check settings)
AMD Radeon RX 6800M 226 fps (+5%) 214 fps (+8%) 201 fps (+17%)
AMD Radeon RX 6600M 215 fps 199 fps 172 fps


Actually, we are quite surprised by the end result. The Radeon RX 6800M is always faster but not by much. On Low and Medium, the performance gap isn’t that big while on Ultra Nightmare quality, the bigger GPU is 17% faster. When we add the end prices in the mix it seems that the Radeon RX 6600M is a great mid-ranger, at least when it comes to DOOM Eternal.
