Intel may not have officially shown its desktop aimed 10th Gen Comet Lake-S desktop CPU lineup at CES 2020 but benchmarks for the Core i9 10 core and the Core i5 6 core processors have leaked out online. The latest leak comes from a Taobao DIY market reporter (via Momomo) who has posted a video of the two ES (Engineering Sample) chips and tested them on an OEM motherboard, featuring the new LGA 1200 socket.

The two processors tested might be compared to the Core i9-10900K and the Core i5-10600K that leaked out last week but are in fact entirely different chips that are in ES (Engineering Sample) state which means that they aren't based on the final die/revision/specs. This is made clear with CPU-z screenshots which shows that the Core i9 10 core chip has a base clock of just 2.50 GHz which is much lower than the expected base clock of 3.7 GHz on the Core i9-10900K. Even the 65W, Core i9-10900 has a higher base frequency of 2.8 GHz. The same is true for the Core i5 6 core chip which has a base clock of 3.0 GHz and that too is lower than both, the 'K' 125W and the standard 65W variants.
