Intel Xeon W-10855M vs Intel Core i7-6700K
Intel Xeon W-10855M
► remove from comparisonThe Intel Xeon W-10855M is a high-end processor for laptops with six cores based on the Comet Lake architecture (CML-H, 4th generation of Skylake). The processor clocks at between 2.8 and 4.8 GHz (probably 4.4 GHz with 6 cores) and can execute up to twelve threads simultaneously thanks to Hyper-Threading. The processor is still manufactured in the old 14nm (14nm++) process.
The Comet Lake architecture is similar to Coffee Lake and offers the same features and is produced in the same 14nm process. Other than the improved clock rates, the memory controller now also supports faster DDR4-2933 RAM. More information on Comet Lake and all the models and articles on it can be found here.
The Intel Xeon W-10855M supports the management features vPro, TXT and SIPP and is the professional version of the Core i7-10850H with slightly higher clock speeds (+100 MHz base speed).
Performance
The performance of the Xeon W-10855M should be similar to the old top model Core i7-8950H (6 cores, 2.9 - 4.8 GHz). Thanks to the 6 cores and high Turbo speeds, even demanding applications should run fine on the CPU. However, long term performance is always depending on the laptop cooling system and system configuration.
Graphics
The integrated Intel UHD Graphics P630 iGPU is supposed to offer a similar performance as the UHD630 in the Core i7-9750H. As a low-end solution it will only run 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.
Intel Core i7-6700K
► remove from comparison
The Intel Core i7-6700K is a high-end quad-core desktop processor based on the Skylake architecture, which was announced in August 2015. The CPU, which is manufactured in a 14 nm process, runs at 4.0 up to 4.2 GHz (2 cores: 4.0 GHz, 3 cores: 4.0 GHz, 4 cores: 4.0 GHz) and can execute up to 8 threads simultaneously thanks to Hyperthreading. Being a so called "K"-model, the Core i7-6700K has a free multiplier and can be easily overclocked.
Performance
Even though the Core i7-6700K has a slightly lower clock than the old i7-4790K (4.0 GHz - 4.4 GHz), the performance is slightly better compared to the Haswell predecessor. Depending on the application, the per-MHz performance was increased by roughly 5-10 %. Even the most demanding applications and games are no problem for the high-end CPU.
Graphics
Graphics are handled by the integrated Intel HD Graphics 530 with 24 EUs (Execution Units), which is clocked at 350 - 1150 MHz. Compared to the HD Graphics 4600 (Haswell, 20 EUs), the performance is increased by around 25 percent. The overall GPU performance is still low-end, so modern games can, if at all, only be played smoothly with low settings.
Power Consumption
The TDP was slightly raised from 88 to 91 Watts compared to the predecessor.
