Itís tough to get overly excited about Kaby Lake, a stopgap release intended to fill the void left by Cannonlakeís delay, but donít forget that Intel still has Broadwell-E on the roadmap. Intel plans on launching Broadwell-E to the enthusiast market later this year, and in the meantime Overclock.net forum user Silicon Lottery posted a handful of benchmarks comparing the Core i7-6950X to a Core i7-5960X, a Haswell-E CPU.
 
The Core i7-6950X is expected to be Intelís flagship Broadwell-E processor. Itís built on a 14nm manufacturing process, has 10 cores with Hyper Threading support, and wields 25MB of L3 cache. What Silicon Power benchmarked was an engineering sample, which is a pre-release version thatís typically intended to test compatibility and to give system builders a jumpstart on designing products.
 
Silicon Lottery ran the Core i7-6950X at the same 3GHz base and 3.5GHz boost clockspeeds as the Core i7-5960X, though itís not clear if thatís also the default clocks of the Broadwell-E part or if he did that just for the sake of comparison. Either way, the Broadwell-E CPU has a core count advantage and more L3 cache than the 22nm Core i7-5960X, which is an 8-core chip with Hyper Threading and 20MB of L3 cache. Both have a 140W TDP and are compatible with Intel X99 motherboards with LGA 2011-3 sockets.
 
As for the benchmarks, the Core i7-6950X scored 1,904 (multi-core) and 151 (single-core) in Cinebench, versus the Core i7-5960X scoring 1,592 and 160 in the same tests. Thatís about 10 percent for Broadwell-E in the multi-threaded portion, but interestingly the Haswell-E CPU scored a little higher in Cinebenchís single-threaded test.
 
In XTU, the Core i7-6950X scored 2,354, topping the Core i7-5960Xís score of 2,001. Broadwell-E also showed generally faster performance in AIDA64ís memory and cache benchmarks.
 
Silicon Lottery was able to squeeze some nice overclocking results out of Broadwell, though not quite as high as Haswell-E.
 
ďDefinitely not clocking as well as Haswell-E, but that was to be expected. We're looking at 4.3-4.4GHz to get stable here,Ē Silicon Lottery said.
 
At 4.5GHz, he managed to complete a multi-threaded Cinebench run, which returned a score of 2,327.
 
These arenít the only Broadwell-E benchmarks on Overclock.netís forums. User Maintenance Bot pitted a Core i7-6850K against a Core i7-5820K. He didnít compare singli-threaded Cinebench scores, but in the multi-threaded run, the Broadwell-E part posted a higher result (1,311 versus 1,191)..
