Intel's Core i7-8700K flagship processor has once again been tested, this time in 3DMark. The latest benchmarks show performance comparison of the upcoming chip against current generation SKUs from Intel and AMD.

Intel Core i7-8700K 6 Core Flagship Processor Benchmarks Leak Out - 3DMark 11 CPU Performance Revealed

The Intel Core i7-8700K will be the fastest mainstream and also an enthusiast processor based on its unlocked design.

The chip will be compatible with the LGA 1151 socket and rumors are that board makers will extend support of Coffee Lake onto 200-series and even 100-series platforms. The chip will be Intel’s first hexa core product and will be based on the 14nm process node.

In terms of clock speeds, we are looking at a 3.7 GHz base frequency which boosts up to 4.3 GHz (6 core), 4.4 GHz (4 core), 4.6 GHz (2 core) and 4.7 GHz (1 core). These clocks are really impressive so we can expect much faster gaming performance on Coffee Lake parts than the current generation of CPUs.

The chip is fully unlocked allowing for overclocking and comes with a TDP of 95W. There’s 12 MB of L3 cache on board along with a GT2 tier iGPU. The chip supports native memory of DDR4-2666 MHz and up to 4400 MHz+ (OC). There's no word on pricing yet but we can expect it to cost around $349 US when it launches in Q3 2017.
