Graphics Benchmark Results
When I first started testing this system, I made a list of all the hardware specifications. I was confused by the GTX660 graphics card, which only had 1.5GB of VRAM. I was certain that GTX660s had 2GB. Visiting NVIDIA’s GeForce web page cleared things up: the Lenovo Erazer X700 uses a special OEM version of the GTX660, with less memory and lower clock speeds than the retail version.
For 1080P gaming, the loss of 512M of VRAM shouldn’t be an issue in most cases. However, the non-standard amount of memory will preclude using a retail GTX660 to set up an SLI system (and Lenovo didn’t include an SLI bridge anyway).
For graphics testing, I used Unigine Heaven 3.0, Lost Planet 2.0 Benchmark, and Metro 2033′s built-in benchmark test. Here are the specific settings:
Unigine Heaven 3.0: 1920×1080, high shaders, extreme tesselation, 8xAA, 16xaf
Lost Planet 2.0: 1920×1080, MSAA4x, all other settings “High”, Test B
Metro 2033: 1920×1080, DirectX11, very high quality, 4xAA, 16xAF, tessellation, DOF, “Frontline” scene, no PhysX.
Aliens vs. Predator: 1920×1080, very high textures, 4xAA, 16xAF, SSAO, Hardware Tessalation, advanced shadow sampling.
Despite its less-capable graphics card and arguably slower processor, the X700 performance is very close to that of the Ivy Bridge-based system. The largest performance difference was 10% in the Lost Planet 2 benchmark
|Lenovo FPS||3770K/MSI FPS||Difference %|
|Lost Planet 2.0||61.7||67.9||10.0|
|Aliens vs. Predator||47.2||44.3||-6.1|
So the Erazer X700 configuration I have is a more than capable gaming system at 1080p resolutions. I describe my overclocking experience with this system in the next section.
