The first benchmarks results of Intel's flagship Core i7-6950X Broadwell-E processor have been unveiled. The performance results of Intel's top, high-end desktop chip provide us a detailed look at how the chip performs with stock and overclocked configurations. These performance results aren't the first to leak ahead of launch since we got to see the benchmarks of the Core i7-6850K and Core i7-6900K a few days ago too.
Intel's Core i7-6950X is the top dog of the Broadwell-E HEDT family!
Intel Core i7-6950X vs Core i7-5960X Processor Bencnmarks Unveiled - Clocks Up To 4.5 GHz
The Intel Core i7-6950X is the top gun of the Broadwell-E family which is launching at Computex 2016. Intel is going one step ahead with this SKU, offering consumers 10 cores and 20 threads. The chip was tested against the last flagship offering from Intel, the Core i7-5960X (Haswell-E) which is a 8 core, 16 thread chip. The CPUs based on Broadwell utilize the modern 14nm process node while the Haswell CPUs utilize the 22nm process node.
The testing was performed by Silicon Lottery at overclock.net forums. Their site has already listed the Core i7-6950X sample on their main page with a price tag of $2099 US. The chip is a engineering sample but does run and can be used on any X99 motherboard.
"This is an pre-release engineering sample (ES) processor. Because Broadwell-E has not yet launched, you may come across various issues if your motherboard bios is not yet compatible.
Returns are NOT ACCEPTED for this processor, all sales are final." via Silicon Lottery
Intel Core i7-6950X and Core i7-5960X Processor Specifications Comparison:
While the Core i7-6850K and Core i7-5820K comparison was technically justified, the Core i7-6950X to Core i7-5960X comparison is kind of not the same as both processors feature different specs and different price range. The Core i7-6950X is Intel's latest processor with 10 cores and 20 threads. The processor will run at a base clock of 3.00 GHz and a 3.50 GHz boost clock. The processor will come in an unlocked package to allow overclocking support to enthusiasts. The processor rocks 25 MB of L3 cache (2.5 MB per core) and will be compatible with current generation X99 motherboards that feature the LGA 2011-v3 socket.

The Intel Core i7-5960X is based on the older Haswell architecture and features 8 cores with 16 threads. The chip is clocked at 3.00 GHz base and 3.50 GHz boost clocks which are identical to the Core i7-6950X but the difference is within the core count with Broadwell-E featuring an extra two cores. The Core i7-5960X also has total of 20 MB L3 cache but does feature the same 140W package as the Core i7-5960X. Since there isn't any deca core processor available on the market, Intel is rumored to bump the price of their Broadwell chip up to 1500 USD which is 500 bucks more compared to the Haswell-E chip.

Intel Core i7-6950X and Core i7-5960X Processor Performance Comparison:
We are aware that our readers love performance numbers and so we will be providing you with those. The chip tested against the Core i7-6950X is technically not the 5960X but its the Xeon equivalent which provides almost the same performance with a difference under 1% at most. Both processors were tested on a ASUS Rampage V Extreme motherboard which features an X99 socket. As indicated previously, Broadwell-E lineup is compatible with the existing and upcoming X99 motherboards. Cooler used was a Corsair H105 which tired its best to keep the chip cool during the tests and under overclocks.
The Core i7-6950X was tested on ASUS's flagship X99 Rampage V Extreme motherboard.
The performance results show us a good increase in performance. A clock-to-clock comparison of 4.00 GHz on both chips yields scores of 1904 (Multi-Threading) and 151 (Single Threaded) on the Core i7-6950X while the Core i7-5960X should score 1592 (Multi-Threading) and 160 (Single Threaded) points. In XTU Benchmark, the 6950X scores 2354 marks against the 2001 marks of the 5960X. The Aida64 numbers show an across the board leverage in memory transfer rates. The tester used 16 GB of DDR4 memory clocked at 3.2 GHz.
