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.

The Intel Core i7-8700K Performance Tests in 3DMark 11 - Can It Be Any Better Than Current 6 Core Parts?
The Intel Core i7-8700K was tested on a Supermicro SuperO CLZ370-CG-L motherboard. This confirms the upcoming Z370 PCH which will be followed by more SKUs in Q1 2018. The Core i7-8700K was tested on the AMD Radeon RX 480 and NVIDIA GeForce GTX 1080 graphics card. The different test cases used fairly identical hardware since the testing was performed by the same user.
We see very similar scores on stock clocks on both tests. The one with the GTX 1080 scored 14,251 points in the physics test which is entirely CPU dependent. The one with the Radeon RX 480 scored 14,021 points which is very close to the other test. Now if we compare these scores to an Intel Core i7-7700K, we are looking at a really good boost in terms of multi-threading performance. Even the likes of Ryzen 5 1600X with 6 cores and Ryzen 7 1700X with 8 cores are beaten by the Intel CPU at stock clocks.
However, these results are not showing a clear picture as different setups provide different results. The other systems may be using faster memory or better system hardware that can directly affect the physics score even if it only takes in account the CPU performance. As we know, faster memory can have a huge impact on CPU performance and the Intel system with Core i7-8700K maybe using memory with native clock speeds (under 3000 MHz) while the other systems can be using higher (OC) series memory.
Intel Core i7-8700K CPU-z Performance:
| CPU Name | CPUz Single Thread Score | CPUz Multi Thread Score |
|---|---|---|
| Intel Core i7-8700K | 2323 | 13980 |
| AMD Ryzen 5 1600X | 1888 | 12544 |
| Intel Core i7-7700K | 2301 | 9993 |
| Intel Core i7-6700K | 2144 | 9124 |
| Intel Core i7-6850K | 1940 | 11170 |
| Intel Core i7-5930K | 1841 | 10676 |
We can definitely expect more performance data in the coming days as the processors are planned for launch later this month.
