Intel’s 10th Gen Comet Lake CPUs Use the Same Die as the Preceding Coffee Lake Parts (Excluding the 10900K)

It’s no secret that Intel’s 10th Gen Comet Lake family is another Skylake refresh with minor modifications to the chip design here and there. It turns out the company is actually using the same exact dies with Comet Lake as it did with Coffee Lake. That holds true for the entire 45W H series lineup and most of the upcoming Comet Lake-S desktop stack.

While this isn’t 100% confirmed as of now, it certainly looks like Intel 10th Gen lineup will re-using the Coffee Lake die for most products. While the 45W high-performance CPUs are essentially overclocked variants of their predecessors, the desktop Comets do see multiple chip-level modifications, the most prominent being the inclusion of hyperthreading and the accompanying increased cache sizes.

With the Comet Lake-S series, there will be one new die, namely the 10-core Core i9-10900K. This will be Intel’s first consumer part with double-figure count counts. The preceding Core i9-9900K was basically an i7-9700K with hyperthreading enabled and a slightly higher boost clock. As such, the performance delta between the two was marginal at best in gaming workloads (SMT is obsolete here).

With the Core i9-10900K, you’re getting two additional cores and a ten-core part with an all-core boost of nearly 5GHz (4.8GHz). This will be the main highlight of the Comet Lake-S launch. The rest of the parts are more or less the same as their predecessors.

The 10th Gen Comet Lake-S desktop processors are slated to hit the market by ending May with an announcement coming later this month.
