The Intel Core i7-8700K Hexa-Core Processor Review

3D Rendering Speed – CINEBENCH R15

CINEBENCH R15 is a real-world 3D rendering benchmark based on the MAXON Cinema 4D animation software. This is a great way to accurately determine the actual performance of a processor in 3D content creation.

CINEBENCH R15 Single Core

This Single Core test is not reflective of real world performance, but it is useful to find out the performance of the individual core.

We already knew from our Ryzen 7 1800X (Price Check) and Ryzen 5 1500X (Price Check) reviews that the Intel Skylake core is about 8% faster than the AMD Ryzen core. Intel made improvements to the Coffee Lake core but do not let the results fool you – most of it is due to the higher clock speed.

When it runs with a single core, the Intel Core i7-8700K has a turbo boost clock of 4.7 GHz – a full GHz over its base clock speed. If we adjust the results to account for the higher clock speed, the Intel Coffee Lake core is about 9.4% faster than the AMD Ryzen core.

CINEBENCH R15 Multi Core

This shows the real-world 3D rendering performance of the five processors. Impressively, the 6-core Intel Core i7-8700K came within 5% of the AMD Ryzen 7 1800X (Price Check), which is an 8-core, 16-thread processor!

Even more impressive is the fact that the Intel Core i7-8700K was 72% faster than the Core i7-6700K in this test. That is a double-digit improvement worth crowing about!

CINEBENCH R15 MP Ratio

The analysis of the Multi-Processing Ratio is useful in checking the efficiency of the SMT implementation. The MP Ratio is independent of the processor’s clock speed.

After adjusting for their clock speed differences, we estimate that the SMT implementation in the Ryzen 7 1800X (Price Check) is about 12% more efficient than Hyper-Threading in the Intel Core i7-8700K.

 

Video Transcoding Speed – HandBrake

HandBrake is a free, open-source video transcoding utility. Video transcoding basically converts a video file from one resolution / format to another. As you can imagine, it’s very compute-intensive. In our test, we converted a 4K video of 1.3 GB in size into a 1080p video (HQ1080p30).

The Intel Core i7-8700K transcoded the 1.3 GB video in just over 5 minutes – about 13.3% slower than the AMD Ryzen 7 1800X (Price Check) and 46% faster than the Core i7-6700K. Very nice!

 

Radial Blur Speed – Photoshop CC 14

The radial blur filter adds the perception of motion to a picture. This is a compute-intensive operation that benefits from multiple processing cores. This radial blur test was performed on a single 13.5 megapixel photo, with a filesize of 4,910,867 bytes.

The Intel Core i7-8700K did very well in this test, applying the radial blur filter in just 8 seconds – less than a second (9%) slower than the AMD Ryzen 7 1800X (Price Check)! It was 57% faster in this test than the Core i7-6700K. Very impressive!
