This past weekend, Intel accidentally leaked some details about the company’s upcoming launch of Core i7 processors on the LGA 2011-3 socket. The flagship part, the Core i7-6950X, will ship with 25MB of L3 cache and has a top turbo clock speed of 3.5GHz. That’s not far from the existing Core i7-5960X, but that’s also an older chip based on Haswell-E, while the Core i7-6950X will be based on Broadwell-E, which is both an architecture improvement and a die shrink. Performance won’t be massively different, but there will be significant savings in power consumption and heat output, and these newer chips should be much easier to tame on an air-cooled setup.
You can look at some performance data on the jump from Haswell-E to Broadwell-E on Anandtech’s review of the Intel Xeon E5 V4 family to get an idea of how much of an improvement there is, but for gaming purposes we shouldn’t see anything more than a 5% jump in CPU-limited situations (and even then, games don’t scale beyond four cores typically). Estimated pricing of the Core i7-6950X could be as much as $1300, so not a lot of people will be snapping these up.
