Intel Core i5-10300H vs Intel Xeon W-11955M vs Intel Core i5-11260H

Intel Core i5-10300H

The Intel Core i5-10300H 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 2.5 and 4.5 GHz (up to 4.2 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. Compared to the predecessor, the Core i5-9300H from 2019, the 10300H is clocked slightly higher (+100 MHz Base, +400 MHz Boost) and supports faster DDR4-2933 RAM.

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 i5-10300H supports no vPro, TXT or SIPP. These business features are available in the faster Core i5-10400H (2.6 - 4.6 GHz) that was released at a later date.

Performance

The average 10300H in our database matches the AMD Ryzen 5 3550H in multi-thread performance. While not a poor result per se, it is indicative of an entry-level H-class CPU that is unlikely to meet the needs of hardcore gamers, professional videographers and similar clientele.

Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solution of your system is.

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

The Core i5 has a default TDP (also known as the long-term power limit) of 45 W, a value that laptop makers are free to reduce slightly, 35 W being the lowest Intel-recommended value. Doing so would result in lower clock speeds and lower performance. Either way, a proper cooling solution is a must for a CPU like this.

The i5-10300H is manufactured on one of the old 14 nm Intel processes for lower-than-average, as of late 2022, energy efficiency.

Intel Xeon W-11955M

The Intel Xeon W-11955M is a high end octa core SoC for laptops and mobile workstations. It is based on the Tiger Lake H45 generation and was announced in mid 2021. It integrates eight Willow Cove processor cores (16 threads thanks to HyperThreading). The base clock speed depends on the TDP setting and at 45 Watt is at 2.6 GHz. The single core boost speed can reach up to 5 GHz (ITBM 3.0, also two cores), all cores can reach up to 4.5 GHz. The CPU offers 24 MB level 3 cache and supports DDR4-3200 memory. Similar to the Core i9-11950H, the Xeon W-11955M supports SIPP, vPro and TXT. In addition to this, the Xeon line supports ECC memory.

Performance

The average W-11955M in our database is in the same league as the Ryzen 7 4800H, Core i7-11850H, Core i7-1360P, as far as multi-thread benchmark scores are concerned. This is a fairly fast chip, as of early 2023.

Your mileage may vary depending on how competent the cooling solution of your laptop is, and how high the CPU power limits are.

The SoC also included the improved Xe graphics card called UHD graphics with all 32 EUs.

Furthermore, Tiger Lake SoCs add PCIe 4 support (20 lanes in the H45 series), AI hardware acceleration, and the partial integration of Thunderbolt 4/USB 4 and Wi-Fi 6E in the chip.

Power consumption

This Xeon series chip has a default TDP, also known as the long-term power limit, of 35 W to 45 W, the expectation being that laptop makers will go for a higher value to get better performance.

The W-11955M is built with Intel's third-gen 10 nm process marketed as SuperFin for average, as of early 2023, energy efficiency.

Intel Core i5-11260H

The Intel Core i5-11260H is a mid range hexa core SoC for gaming laptops and mobile workstations. It is based on the Tiger Lake H45 generation and was announced in mid 2021. It integrates six Willow Cove processor cores (12 threads thanks to HyperThreading). The base clock speed depends on the TDP setting and at 45 Watt is at 2.6 GHz. The single and dual core boost speed can reach up to 4.4 GHz, all cores can reach up to 4 GHz. The CPU offers 12 MB level 3 cache and supports DDR4-3200 memory.

Thanks to the new Tiger Lake architecture, the i5-11260H should be able to reach the level of the high clocked Intel Core i7-10850H (Comet Lake-H, 6 cores, 2.7 - 5.1 GHz, 16 MB L3) in single and multi threaded performance. Compared, to current AMD offerings, the 11260H should perform similar to a Ryzen 5 5600H (6 cores, 2.4 - 3.3. GHz, 16 MB L3 cache) or the 5600HS when the TDP is set to 35W.

The SoC also features a much improved UHD Graphics (16 EUs) iGPU based on the Xe architecture.

Furthermore, Tiger Lake SoCs add PCIe 4 support (20 lanes in the H45 series), AI hardware acceleration, and the partial integration of Thunderbolt 4/USB 4 and Wi-Fi 6E in the chip.

The chip is produced in the improved 10nm process (called 10nm SuperFin) at Intel, which should be comparable to the 7nm process at TSMC (e.g. Ryzen 4000 series). The default TDP is rated at 45 W at 2.6 GHz base speed, at 35 Watt the base clock speed decreases to 2.1 GHz (cTDP down).
