Intel Xeon E7-4850 v2 

Released February, 2014
  • 2.3 GHz
  • Dodeca core

The E7-8800 V2 chips would work in configurations that feature up to eight sockets and will feature 15 cores per CPU, along with Hyperthreading, resulting in 30 threads per socket.

Intel releases Xeon E7 v2 chipset

by Nick Farrell |
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 Roadmap Including Xeon E7 v2 Lineup

by Scott Michaud |
This should be the first time since Sandy Bridge-E (2011) that expensive PCs get a healthy boost to single-threaded performance, clock for clock.
Heading into the third quarter, we should see Haswell-E make an appearance for the enthusiast desktop and moderately high-end server.

Ivy Bridge-EX Arrives – Intel Xeon E7 v2 Released with 20 New SKU Lineup

by Syed Muhammad Usman Pirzada |
The chip features an insane 4.31 billion transistors and a massive die size of 541mm2 with a modular architecture which splits the cores into blocks of three, each block has five cores with their own L3 cache, embedded ring bus and I/O..
Intel is preparing their flagship Xeon E7-8890 V2 chip codenamed Ivytown which is the first chip from Intel to boast a core count of 15 coming one step closer to AMD’s Opteron 6300 series which has 16 cores on the top most model.

Intel Readying 15-core Xeon E7 v2

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.
