Radeon HD 6990M And GeForce GTX 580M: A Beautiful Lie

We’ve been more than outspoken about the naming AMD and Nvidia use for their mobile GPUs. Are they really trying to mislead buyers, though? We briefly examine their methodology and frame that against the limitations of high-end mobile computing.

Benchmark Results: DiRT 3

We added DiRT 3 testing to our notebooks only after returning the mobile platform with GeForce GTX 580Ms installed, leaving AMD to stand on its own in this desktop-versus-notebook graphics comparison.

Ouch. We would have expected 1280x720 to be CPU-bottlenecked, but the single desktop card is already outpacing a pair of notebook modules bearing the same model number (minus that very important M, of course) by a wide margin. Buyer beware!

We think its both sad and wrong that two Radeon HD 6990Ms can’t beat one Radeon HD 6990 when complemented by the same CPU, memory speed, and chipset. Pathetic.
