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.

Intel releases Xeon E7 v2 chipset

by Nick Farrell |
www.fudzilla.com
Beyond two times better performance power, Intel is promising a few other upgrades with the next generation of this data-focused chipset, including triple the memory capacity, four times the I/O bandwidth and the potential to reduce total cost of ownership by up to 80 percent.
There was also talk of 40W, 1.4GHz models at ISSCC but they have not been announced yet.

Intel Readying 15-core Xeon E7 v2

by Ian Cutress |
www.anandtech.com
2.8 GHz Turbo Frequency (though the design will scale to 3.8 GHz).
Judging by the available information, it would seem that Intel are preparing a stack of ‘Ivytown’ processors along this design, and thus a range of Xeon E7 processors, from 1.4 GHz to 3.8 GHz, drawing between 40W and 150W, similar to the Xeon E5 v2 range.

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

by Ian Cutress |
www.anandtech.com
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.
