Intel Xeon E5-2697 v2 and Xeon E5-2687W v2 Review: 12 and 8 Cores

by Ian Cutress |
The ultra-high-end enthusiast also wants all the bells and whistles, such as overclockability, a good range of DRAM speed support and top quality construction materials.
My goal was to find out where these two CPUs stand in what I consider ‘an enthusiast user’s scenario’, and as such we used the same benchmarks as in the AMD Kaveri launch article, involving gaming, compression, rendering, video conversion and 2D image to 3D modeling creation.

Xeon E5-2600 V2 Price List: Server Ivy Bridge-EP

by Ian Cutress |
With any luck we should be getting a couple of Ivy Bridge-E based server motherboards in to test, along with Xeon processors.
> Haswell Xeons, these processors, destined for 2P systems, will take on the E5 26xx naming scheme with V2 on the end, with L designating low power versions.
