The first preview of the Intel Core i5-10400 6 Core, Comet Lake-S, Desktop CPU has been posted by TecLab. The Chinese review channel over at Bilibili (via Momomo_US) covers the performance benchmarks of the chip and compares it against its predecessor and also an 8 core, 9th Generation Core i7 CPU.

The Intel Core i5-10400 is a 6 core and 12 thread processor which replaces the Core i5-9400 which had 6 cores and 6 threads. Intel didn't offer SMT on various 9th Generation processors but due to increased pressure from the competition, they have decided to offer SMT on all 10th Gen CPUs. In terms of specifications, the Core i5-10400 is a 65W chip and doesn't feature overclocking support.
