Gaming System Testing Methodology
Lenovo’s decision to base the Erazer X700 on an Intel X79 platform is a little strange in 2013; the Core i7-3820 is a Sandy Bridge-era CPU, and we’re two generations beyond that now. I’ll run some CPU and gaming/graphics tests, and when possible I’ll include CPU performance results from a modern Haswell-based 4770K system.
Pressing the Overclock button on the system sets the CPU multiplier to 41x, effective at the next restart. Using Erazer Control Center, I was able to set the multiplier to 43x. I ran the CPU and system benchmark tests at stock, 41x, and 43x speeds.
The NVIDIA GTX660 graphics card in this system is a special OEM version that is different from the retail version. While the retail GTX660 has 2GB of memory, a 980MHz base and 1033MHz boost clock, and 6Gbps memory, the OEM version has 1.5GB of memory, and 823MHZ base clock and 888MHz boost clock, and 5.8Gbps memory. I don’t have a retail GTX660 to test against, but I wouldn’t expect the performance of this OEM card to be noticeably lower than the retail card except in benchmarks. However, since the OEM card has a different memory size than the retail card, you wouldn’t be able to configure an SLI system with the included card and a retail GTX660.
For a comparison on the graphics tests, I’ve included the results from my testing of the MSI GTX660-Ti Power Edition video card. The test system used an Ivy Bridge based Core i7-3770K CPU on an Intel DZ77GA-70K motherboard equipped with 8GB of DDR3-1600 memory at 9-9-9-27 timings. While the settings for each graphics benchmark were the same, remember that there’s a significant difference between these two versions of the GTX660 as well as the two CPUs.
