Tom's Hardware acquired, from... somewhere, an early engineering sample of the upcoming Core i7-4960X. Intel was allegedly not involved with this preview and were thus, I would expect, not the supplier for their review unit. While the introductory disclaimer alluded to some tensions between Intel and themselves, for us: we finally have a general ballpark of Ivy Bridge-E's performance. Sure, tweaks could be made before the end of this year, but this might be all we have to go on until then.
Both images, credit, Tom's Hardware.
When browsing through the benchmarks, I noticed three key points:
- Single-threaded: slightly behind mainstream Haswell, similar to Sandy Bridge-E (SBE).
eight cores(Update 1: This was a 6-core part) are better than SBE, but marginal given the wait.
- Power efficiency: Ivy Bridge-E handily wins, about 30% more performance per watt.
These results will likely be disappointing to enthusiasts who seek the highest performance, especially in single-threaded applications. Data centers, on the other hand, will likely be eager for Xeon variants of this architecture. The higher-tier Xeon E5 processors are still based on Socket 2011 Sandy Bridge-E including, for instance, those powering the highest performance Cluster Compute instances at Amazon Web Services.
But, for those who actually are salivating for the fastest at all costs, the wait for Ivy Bridge-E might as well be postponed until Haswell-E reaches us, allegedly, just a year later. That architecture should provide significant increases in performance, single and multi-threaded, and is rumored to arrive the following year. I may have just salted the wounds of those who purchased an X79 motherboard, awaiting Ivy Bridge-E, but it might just be the way to go for those who did not pre-invest in Ivy Bridge-E's promise.
Again, of course, under the assumption that these benchmarks are still valid upon release. While a complete product re-bin is unlikely, we still do not know what clock rate the final silicon will be capable of supporting, officially or unofficially.
Keep calm, and carry a Haswell?
