Encoding and Rendering Performance
Handbrake is a popular application for encoding video and we've used it to convert a 4K H.264 video to 1080p using H.265 and recorded the average frame rate. Here the Ryzen 5 1700 spat out 11 fps on average while the 1800X managed 12.6 fps. Not bad but the new Core i7-8700K went complete beast mode with 13.8 fps making it 10% faster than the 1800X and 11% faster than the 7800X.
Next up we have Premiere and we know this application likes cores, but it also loves clock speed. The new Core i7-8700K completed the encode in 195 seconds which is just a few seconds slower than the Ryzen 7 1800X.
Moving on to the rendering tests we have Blender and first we're running the Ryzen Graphic 27 test. Again the 8700K finds itself in a Ryzen 7 sandwich with a completion time of 25.8 seconds. That made it almost 40% faster than the Core i7-7700K and Ryzen 5 1600 in this test.
The Gooseberry workload paints somewhat of a different picture. In this extreme benchmark the 8700K is able to pull ahead of the Ryzen 7 1800X and is now 14% faster and 8% faster than the 7800X.
Corona comes as a standalone benchmark. It renders a fixed scene six times and we take the time it takes to complete the task. This time the 8700K is closer to the R7 1700 than it is the 1800X but even so a render time of just 142 seconds for the six-core CPU is mighty impressive.
POV-Ray is another ray-tracer, it's been around for many years and we're using the official benchmark. Again, the 8700K is closer to the R7 1700X than it is the 1800X, but even so it's a good bit faster than the now redundant 7800X.
