Intel Core i5-1155G7 vs Intel Core i9-10900K
Intel Core i5-1155G7
► remove from comparison
The Intel Core i5-1155G7 is a power efficient quad-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation that was announced in mid 2021 as part of the refresh. It integrates four Willow Cove processor cores (8 threads thanks to HyperThreading). The base clock speed depends on the TDP settings and ranges from 1 GHz (12 Watt TDP) up to 2.5 GHz (28 Watt). Boost clock speed is 4.5 GHz.
Tiger Lake SoCs add PCIe 4 support (4 lanes), AI hardware acceleration, and the partial integration of Thunderbolt 4 / USB 4 and Wifi 6 in the chip.
Another novelty is the integrated Xe graphics adapter with 80 EUs based on the completely new Gen 12 architecture. It offers a significantly higher performance compared to the older Iris Plus G7 (Ice Lake).
Performance
The average 1155G7 in our database proves to be a very decent mid-range processor, as of mid 2022, trading blows with the Core i7-10810U and the Ryzen 5 4500U as far as multi-thread benchmark scores are concerned. While perhaps not the best option for power users, this Core i5 will make most consumers happy, providing for short load times and generally pain-free experience.
Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solution of your system is.
Power consumption
This Core i5 series chip has a default TDP, also known as the long-term power limit, of 12 W to 28 W, the expectation being that laptop makers will go for a higher value in exchange for higher performance. Either way, this is a tad too high to allow for passively cooled designs.
The i5-1155G7 is built with Intel's third-gen 10 nm process marketed as SuperFin for lower-than-average, as of early 2023, energy efficiency.
Intel Core i9-10900K
► remove from comparison
The Intel Core i9-10900K is a high-end processor for desktops with ten cores based on the Comet Lake architecture (CML-S, 4th generation of Skylake). The processor clocks at between 3.7 and 5.3 GHz (all 10 cores up to 4.8 GHz) and can execute up to twenty threads simultaneously thanks to Hyper-Threading. The 5.3 GHz can be only achieved below 70°C core temperature (Thermal Velocity Boost of 100 MHz).
The processor is still manufactured in the old 14nm (14nm++) process. Compared to the predecessor, the Core i9-9900K, the 10900K offers increased clock speeds and two more cores. Thanks to the free multiplicator, the CPU can also be easily overclocked (but may not have much headroom).
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.
Performance
Thanks to the high Turbo Boost, the CPU is the fastest gaming CPU available at the time of announcement. Using all cores, the i9 however is slower than the top Ryzen CPUs (like the Ryzen 9 3950X) which offer more cores.
Graphics
The integrated Intel UHD Graphics 630 iGPU is supposed to offer a similar performance as the UHD630 in the Core i7-9900K. 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 125 Watts (PL1) but under full load up to 250 Watt are consumed (PL2). In default mode these 250 Watt and therefore high clock speeds can be maintained for up to 56 seconds, however, all boards offer the option to alter these settings.
