Intel Broadwell-E Core i7-6950X vs Core i7-5960X Benchmark Results Leaked – Overclocked Performance at 4.5 GHz Detailed-February 2024
Feb 12, 2026 9:43 PM

The first benchmarks results of Intel's flagship Core i7-6950X Broadwell-E processor have been unveiled. The performance resultsof 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!

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 with10 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.
