The 14nm chip from Intel is about 4 to 5 percent faster than AMD's 7nm Zen 2 design, which is actually quite impressive. This makes the 10900K about 15-16 percent faster than the current-gen 9900K.
With the 10-core and 12-core chips going head-to-head it’s clear from the 3DMark benchmarks dug up by perennial leaker, TUM_APISAK, that the higher clock speed of the Intel processor is more than able to make up for the difference in core counts. At least that’s the way it looks like it’s going in rendering and gaming tasks.Intel isn't in an ideal spot, but the company is still able to squeeze some more performance out of its aging 14nm designs. The downside is that the 10900K has a 125W TDP, whereas AMD's 3900X has a 105W TDP.
