Ivy Bridge-E HEDT Core i7 has six-core Xeon die

Ivy Bridge-E HEDT Core i7 has six-core Xeon die

So the Ivy Bridge-EP Xeon E5 v2 series has three different dies in its spread reports vr-zone. One of them is actually a native, compact, six-core die with 15 MB L3 cache – the other two being 10-core 25 MB L3 dies, and 12-core 30 MB L3 dies. That smallest die is the base for the six-core Ivy Bridge-E Core i7 LGA2011 series, so there are no ‘turned off’ cores off a larger die here. You still have the quad-channel DDR3-1866 memory controller, which should give more memory O/C headroom than the predecessor, and the two QPI channels from the Xeon die necessary for multi-socket operation are turned off on the desktop, of course.

The impact? A big plus compared to the old crippled gigantic eight-core 32 nm die with three out of four of its cores enabled. Now, it is a comparatively small six-core die without the huge graphics portion, but with lotsa PCI-E v3.0 and very wide memory should have very good O/C potential in the production version, since Intel had an extra year plus to solve any leakage problems on the 22 nm FinFET process. Also, we assume, Intel will continue to use soldered heat spreader solution on high end LGA2011 chips, rather than the el cheapo toothpaste seen on the desktop Ivy Bridge chips.

As for the extras seen in the Haswell CPU, like AVX2/TSX etc, that Ivy Bridge-E doesn’t have yet, well it will take time anyway for the high end apps and such to fully use those extensions, and then, in a year’s time, it’ll be just in time for Haswell-E Core i7 follow-ons (in an incompatible revision of LGA2011 socket, though).

This is interesting. I'm assuming then the cheapest one will be the 6-core die with 2 cores disabled...

And assuming the cheapest one will cost you as much as much as an entire modern mid-range gaming computer.

Anyone who buys these CPUs for anything that isn't server or serious workstation purposes either has terrible financial priorities or has way too much money to just throw away.

I would be interested to see how these perform though, especially against other server CPUs such as SPARC.

^The cheapest SB-e is around $290 actually cheaper than a 4770k what's your point.

Cheapest 6-core I believe is what he's on about.
