Intel Xeon E7-8880L v2 

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.

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.

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.

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.

They will also carry 30 MB of L3 cache and have quad-channel DDR3-1866 memory support, per socket.
