i7-4960X Preview: Ivy Bridge-E, Benchmarked

Disclaimer: The following preview is based on an early engineering sample Core i7-4960X. Intel was not involved in the story, and was not asked for comment prior to its publication. In fact, starting with our Haswell preview, the company started a policy of excluding us from certain discussions. So yeah. There’s always more of that to look forward to.

Meet Ivy Bridge-E, The Upgrade Path For X79 Express

Right now it looks like Ivy Bridge-E-based processors will launch in September, putting us a couple of months out. Multiple models are expected, but I’ve only seen official specifications for two: the Core i7-4960X and Core i7-4820K. Earlier leaks showed that the -4960X would be a six-core CPU, while the -4820K hosts four cores. Purportedly there’s a Core i7-4930K in there as well, though I haven’t received one yet.

From most angles, the Ivy Bridge-E-based parts look a lot like Sandy Bridge-E, except for the adoption of Intel’s Ivy Bridge architecture. That means a handful of IPC-oriented improvements in the core, cache, and memory controller, similar to what we described in Intel Core i7-3770K Review: A Small Step Up For Ivy Bridge. Of course, gone is the emphasis on graphics. That means Ivy Bridge-E is really about the updated core, a memory controller rated for 1866 MT/s (instead of 1600), official PCI Express 3.0 compliance (remember, Sandy Bridge-E only claimed 8 GT/s signaling support), and 22 nm manufacturing. Ivy Bridge-E-based CPUs should also be unlocked up to 63x multipliers (versus SNB-E's 57x), you should be able to hit memory data rates beyond 2400 MT/s, Ivy Bridge-E supports XMP 1.3 (compared to SNB-E's XMP 1.2), and you'll have access to real-time ratio, voltage, and power limit settings.

You still get 40 lanes of PCI Express connectivity, divisible into as many ports as you need for four-way CrossFire and SLI. You’re still dealing with a quad-channel memory controller, though the higher data rate increases peak bandwidth to 59.7 GB/s from 51.2 GB/s. And you’re dropping Ivy Bridge-E into the aging X79 Express platform. The good news is that your old motherboard still works; you don’t have to buy a new one. Unfortunately, the chipset only offers two SATA 6Gb/s ports, it doesn’t feature native USB 3.0, and you don’t get to enjoy new capabilities like SATA Express, which will surface alongside Haswell-based 9-series chipsets early in 2014.

First news post, please correct if I missed something

It seems these could be fun for Benchmarks (higher memory speeds and multi) but for the average user on a CLC/air/water, the only significant improvement will be the memory speeds. Hoping the mem controller is as good as Ivy, pushing 2600-2800Mhz.
