Intel 10th Gen Laptop CPU at 5 GHz Spotted Before Release

The Intel Core i9-10880H, which should be the direct successor to last year's i9-9880H, hasn't been announced yet, but benchmarks results are already creeping up. Hardware leaker @_rogame (opens in new tab) reportedly found the upcoming mobile chip in a 3DMark submission yesterday.

The i9-10880H (codename Comet Lake-H) is expected to arrive sporting eight cores (opens in new tab)and 16 threads (opens in new tab)like its predecessor. Besides the improved clock speeds (opens in new tab), there isn't any significant architectural changes with Comet Lake over the i9-10880H's Coffee Lake. Therefore, we expect the i9-10880H to retain the same 16MB of L3 cache (opens in new tab) as the i9-9880H. Being a H-series part, the 14nm processor will likely operate within the 45W envelope.

According to the 3DMark entry, the i9-10880H could come with a base clock (opens in new tab) fixed at 2.3 GHz, which is the same base clock on the prior i9-9980H. The only thing that the i9-10880H has going for it is the higher boost clock. If the 3DMark's report is accurate, the i9-10880H will flex a 5 GHz boost clock, which is 200 MHz higher than the i9-9980H but only by 4.2%.

With the previous generation, Intel offered consumers the i9-9980H and faster i9-9980HK. The latter operates with a 100 MHz and 200 MHz higher base and boost clocks, respectively. It's plausible that Intel would release a i9-10880HK with slightly faster clocks.

So far, the i9-10980HK (opens in new tab) has appeared with a 3.1 base clock and 5.27 GHz boost clock in unconfirmed benchmarks. Given the huge gap between the i9-10980HK and i9-10880H's specifications, there's certainly room for a i9-10880HK to slide in between. 

The i9-10880H and i9-10980HK should be very popular choices for upcoming high-performance mobile workstations and gaming laptops (opens in new tab). However, they'll have to compete with AMD's Ryzen 4000-series (codename Renoir) chips, such as the Ryzen 9 4900H and Ryzen 7 4800H (opens in new tab).

    There will be a few who buy these, then wonder why it only hits 5 GHz for 3 seconds or less on a single core before settling down to all-core speeds of 2.3 GHz to maintain power-budget...

    (I'd be happy to be proven incorrect, and have these maintain decent clock speeds....; I need a new laptop one of these days)

    I am definitely happy to have bought a core i7 8700k... 3.7 ghz base. they have never done better yet
