Intel is releasing two new Comet Lake-H processors.
There have been no official announcements, but Intel has added two SKUs to the Comet Lake-H lineup. A fourth 8-core high-performance processor has been launched according to Intel's own website.
Interestingly, the launch of the processor allegedly arose due to problems with the delivery of the older Core i7-10875H model. This processor is very popular among high-end gaming laptops. After all, this is the fastest Core i7 processor in the lineup.
Compared to the 10875H, the 10870H offers a 100 MHz lower base clock. This doesn't seem like a big difference, but it might be worth considering since many enthusiasts are often advised to disable Intel Turbo. This is because turbocharging does not provide a significant performance improvement, but it does so at the expense of much higher temperatures.
Today on Reddit, the Schenker XMG team announced upcoming supply issues for the higher-end processor model (10870H). It is worth noting that XMG laptops (Neo 15/17) should not experience supply problems over the next 2-3 months:
[…] There is a CPU supply issue on the horizon for the i7-10875H. This situation is similar to that on desktops, where the Intel Core i9-10900K is all out of stock locally and is being replaced in most sales channels by the new Intel Core i9-10850K, which has almost the same performance (same cores, threads, cache, etc.) etc.), but the clock frequency is 0,1 GHz lower. […]
In the meantime, it looks like we have enough CPUs that we can continue to ship the i7-10875H to XMG NEO over the next 2-3 months. I’m not sure yet what will happen next, we’ll see.

In addition, Intel has also launched a new quad-core Core i5-10200H processor, which is the slowest processor in the mobile H series. This processor has a 100 MHz lower base frequency than the 10300H and a 400 MHz lower turbo frequency.
