Benchmarked against Core i7 5820K Haswell-E

On Thursday, a user named Maintenance Bot on the forums posted a sneak peek of what to expect from Intel’s upcoming Core i7 6850K ‘Broadwell-E’ desktop chip.

This is one of four 14-nanometer chips to be unveiled the company’s upcoming high-end desktop (HEDT) lineup later this month at Computex 2016. The full lineup includes the Core i7 6800K, Core i7 6850K, Core i7 6900K and Core i7 6950X.

We first reported on this chip back in December when unveiled Intel’s Broadwell-E lineup six month before launch. According to the leak, the Core i7 6850K is a six-core chip running at 3.60GHz (3.80GHz with Turbo) and features twelve threads, 15MB of L3 cache, a 140W TDP and a ~$550 USD launch price.

For comparison, Intel’s current Haswell-E (HEDT) lineup consists of the Core i7 5820K, Core i7 5930K and Core i7 Extreme 5960X. The company is replacing its unlocked “xx20” part with a model right below it and another right above it – namely, the 6800K and 6850K, and the entire new Broadwell-E lineup will have unlocked multipliers just like their Haswell-E counterparts.

Meanwhile, in Futuremark's Fire Strike Extreme DirectX 11 benchmark (2560x1440p render), the Core i7 6850K scores 9,440 while the Core i7 5820K scores 9,353.

Maintenance Bot also measured the height of the Core i7 5820K and Core i7 6850K and found that the former is 1.87mm thick while the newer chip is just 1.12mm thick. It also features a slightly redesigned heatspreader upon closer inspection.
