Intel Core i9-11900K vs Intel Core i7-8750H

Intel Core i9-11900K

► remove from comparison Intel i9-11900K

The Intel Core i9-11900K is a high-end desktop CPU based on the Rocket Lake architecture. The CPU offers 8 cores and 16 threads clocked at 3.5 - 5.3 GHz (Turbo Boost 3.0 / TVB). With Turbo Boost 2.0, 5.1 GHz can be reached with a single thread. Using all cores, the CPU can clock up to 4.8 GHz. Adaptive Boost enables even higher multi-core frequencies (5.1 GHz all core Turbo) but uses a lot more power.

The TDP is rated at 125 Watt (PL1, power limit sustained load) but the PL2 is set to around 250 Watt for short term boosts (up to 56 seconds).

The Sunny Cove processor cores (known from the Ice Lake mobile CPUs) offer larger caches and an improved IPC (up to 19%). Furthermore, the chip also includes (partly) integrated WiFi 6E and Thunderbolt 4. The platform supports PCIe 4.0 and Intel DL Boost for AI acceleration.

The faster Rocket Lake-S CPUs also integrate a new Intel UHD Graphics 750 that is based on the current Intel Xe architecture (e.g. mobile Tiger Lake) and offers 32 EUs. In the 11900K, the GPU is clocked from 350 - 1300 MHz.

Performance

The average 11900K in our database is in the same league as the Ryzen 7 5800X3D, as far as multi-thread benchmark scores are concerned. Which is an impressive result, as of mid 2022, and good enough for any task imaginable including content creation and professional gaming.

Power consumption

This Core i9 has a 125 W TDP, also known as the long-term power limit. Intel lets PC manufacturers reduce that value somewhat if required, 95 W being the lower limit, which would result in lower clock speeds and lower performance. The reality is, an 11900K can be much more power hungry than either of the two numbers imply simply because of its sheer might but also because it is manufactured on an old 14 nm Intel process that makes for lower-than-average, as of mid-2022, energy efficiency.

Intel Core i7-8750H

► remove from comparison Intel i7-8750H

The Intel Core i7-8750H is a high-end processor for laptops with six cores based on the Coffee Lake architecture and will be announced early 2018. The processor clocks at between 2.2 and 4.1 GHz (4 GHz with 4 cores, 3.9 GHz with 6 cores) and can execute up to twelve threads simultaneously thanks to Hyper-Threading. According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process.

The Coffee Lake architecture is similar to Kaby Lake and differs only in the amount of cores (now six cores for the high end versions) and the improved 14nm process (14nm++ according to Intel).

Performance

Due to the two additional cores, performance has increased by almost 50% compared to a similar clocked Kaby Lake processor like the Core i7-7820HQ (2.9 - 3.9 GHz). Single-core performance has not improved since its Kaby Lake predecessor. As a high-end model, the i7-8850H is suitable for the most demanding applications and games.

Graphics

The integrated Intel UHD Graphics 630 iGPU is supposed to offer a slightly higher performance as its clock rate has been increased by 50 MHz (rumored). The architecture is identical to that of the Intel HD Graphics 630. We do expect a performance improvement, but as a low-end solution it will probably only display current games smoothly at reduced details - if at all.

Power Consumption

Intel specifies the TDP with 45 watts and therefore the i7 is only suited for big laptops with good cooling solutions. Using cTDP-down, the CPU can also be configured to 35 Watt resulting in a reduced performance.
