Although a desktop builder could put two dual-GPU Radeon HD 6990 graphics cards into a single system, notebook builders are stuck with two GPUs at most. MXM modules are simply too small to accommodate two large GPUs, let alone the power circuitry and doubled-up memory resources. So, we're going to put AMD’s mobile graphics in the best possible light by comparing two of its mobile Radeon HD 6990M modules to a single desktop Radeon HD 6990.
Nvidia isn’t getting a pass for its own indiscretions. We're also comparing a pair of its GeForce GTX 580M graphics cards to a single GeForce GTX 580. Nvidia's solution can't be included in as many of the tests, since we no longer have access to the mobile modules we'd need in order to run some of our newer benchmarks. That also explains why the older 280.26 display drivers were used. But it's worth noting that Nvidia is guilty of the same naming practices.
Fortunately, our legacy gaming suite include GPU-busters like Just Cause 2 and S.T.A.L.K.E.R.: Call of Pripyat.
Notebook motherboards are generally pretty limited with regard to their features. So, a budget desktop motherboard using the same chipset makes for the most accurate comparison. ASRock’s X58 Extreme3 fills the need for desktop graphics connectivity.
