Mobility Radeon Vs. GeForce M: The CrossFire Advantage

Benchmark Results: Synthetic Benchmarks

Since all three of today’s notebook configurations employ an identical platform, we decided to get the synthetic benchmarks out of the way before moving on to the big question of game performance.

3DMark shows the GeForce GTX 480M slightly leading the single Mobility Radeon HD 5870, while the dual Mobility Radeon HD 5870s are nearly as powerful as a desktop Radeon HD 5850.

Eurocom’s use of Crucial’s super-fast SSD gives it superb performance in PCMark Vantage, which is the only benchmark in today’s test to rely heavily on drive performance.

The Core i7-940XM has far higher Intel Turbo Boost speeds than the desktop platform, but also bears a lower base speed to help keep heat dissipation down. Base speed is used when all cores are fully loaded, putting the mobile part at a disadvantage in Sandra’s CPU tests.

The desktop platform uses triple-channel mode to trump its mobile rival, yet the mobile configuration’s 17.1 GB/s bandwidth looks huge compared to the dual-channel machines of our recent System Builder Marathon.
