The logic step to move on to the 22nm process, even for the high end Intel CPU gamma, was just a matter of time. Due to the small observed performance increase, we would label this new 22nm generation as a logic evolution. The most shocking performance step I witnessed was when Intel launched their so "called mainstream platform" with the Sandy Bridge processors. In many applications outperforming the high end LGA 1366 processors, without breaking a sweat. For daily users these were a pure treat: the K skew models could be overclocked to 5Ghz on air and even beyond on watercooling. The latter speeds however just for benching purposes. The hexacore versions, aka Sandy Bridge-E, were a solid replacement for the LGA1366 Gulftown processors. Now with Ivy Bridge-E, Intel continues to improve the performance per clock, allowing again better performance then before. More important is that it all can be achieved at a lower power consumption.
While the lack of native USB 3.0 support and especially Thunderbolt might be a setback for some end users. For once it's nice to get a new CPU generation which does not require a motherboard/chipset upgrade to demonstrate it's performance. And yes the new Ivy-E does perform. Sometimes achieving a 5-10% performance improvement over the predecessor, out of the box. Keep in mind that the i7-4960X runs at slightly higher clocks then the i7-3960X. As mentioned before, due to the 22nm manufacturing process, the power consumption is reduced with about 20-30W under load.

One of the main concerns we had with the Sandy Bridge-E generation was that the DRAM speeds were usually limited to 2400MHz or even lower for daily stability when running high quantity kits. The 32GB 2666C11 CORSAIR Vengeance Pro kit was a test for the Integrated Memory Controller of the i7-4960X ES. Though even with tighter timings, the CPU remained stable during our test suite. With lower quantity aka 4GB Dimms 2800MHz or even higher is perfect possible. Ofcourse it's not all about speed and still a balance has to be found between MHz and DRAM timings to optimize the efficiency of the platform.
Intel refers to this CPU as the ultimate Gaming CPU. Indeed this is correct if one wants to build a multiple GPU and unlimited budget PC. However most game PCs we spot at LAN parties, mostly have one, max two graphics cards. For Gamers it's better to step down to the more mainstream Haswell or even Ivy Bridge CPUs, as mostly games do not even utilize more than 4 threads. However the quad core i7-4820K CPU might become a very interesting Processor. It bridges higher affordability with the multi GPU ability of the LGA2011 platform. The hexacore Ivy-E versions are more targeted at those that need all the crunching power they can get in a desktop PC. People that do a lot of video rendering, photo editing stuff, infact all programs that can properly address the available cores.
For those that don't care to cash out and want the fastest hexacore crunching processor out of the box, this i7-4960X perfectly fits that bill. For most, the i7-4930K will be more than fast enough or as fast, when slightly overclocked, this at a far better price/performance ratio. Once we get the 4820K and 4930K samples in the [M]Lab we will continue to test these new Ivy-E CPUs and might bring a more focused article versus the other more common CPUs on today's market.
Die hard Benchers are obliged to invest in one of the two six core versions to max out the scores in some 3D tests. If all CPUs can do at least 5600MHz under cold, it will reflect the performance of a 200MHz higher running Sandy Bridge-E CPU. A must buy then, let the CPU binning game start (again) to find them +6GHz gems.
Intel keeps on sucessfully improving their CPU lineup, no focus alike the competition on raw MHz. In 2013 it all evolves around efficiency tuning and reducing the power consumption. The price tag of the Extreme edition CPUs is always around the same 1000 dollar mark. Most will skip this CPU for the far more affordable 4930K edition as the overclock potential will be as good and in some cases even better. Bang for the buck the 4930K is unbeatable for those that really require heavy duty six core action.
To sum it up, with Ivy Bridge-E, the performance and power consumption improvement is present, nothing earthshattering, nevertheless again a solid and nice evolution for the Intel lineup.
Let's await the Tock revolution next year...
