Intel Xeon W-10855M vs Intel Core i5-10400H

Intel Xeon W-10855M

► remove from comparison

The 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 i5-10400H

► remove from comparison Intel i5-10400H

The Intel Core i5-10400H is a fast processor for laptops with four cores based on the Comet Lake-H series (4th generation of Skylake architecture). The processor clocks at between 2.6 and 4.6 GHz (up to 4.4 with 4 cores) and can execute up to eight threads simultaneously thanks to Hyper-Threading. According to Intel, the CPU is manufactured in 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 Core i5-10400H supports the management features vPro, TXT and SIPP. 

Performance

The performance should be slightly better than the old Core i7-8809G (Quad-Core 3.1 - 4.2) which was the fastest mobile quad core by Intel.

Graphics

The integrated Intel UHD Graphics 630 iGPU is supposed to offer a similar performance as the UHD630 in the Core i5-9300H. As a  low-end solution it will probably only run current games smoothly at reduced details - if at all.

Power Consumption

Intel specifies the TDP with 45 watts and therefore the i5 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.
