AMD Ryzen 7 3750H vs Intel Core i7-10700K vs Intel Core i9-10900K

AMD Ryzen 7 3750H

The AMD Ryzen 7 3750H is a mobile SoC that was announced in January 2019. It combines four Zen+ cores (8 threads) clocked at 2.3 - 4 GHz with a Radeon RX Vega 10 graphics card with 10 CUs (640 Shaders) clocked at up to 1400 MHz. Compared to the similar Ryzen 7 3700U, the 3750H offers a 20 Watt higher TDP and therefore a better performance under long periods of load. The integrated dual-channel memory controller supports up to DDR4-2400 memory. As the features of the Picasso APUs are the same compared to the Raven Ridge predecessors, we point to our Raven Ridge launch article.

Picasso SoCs use the Zen+ microarchitecture with slight improvements that should lead to a 3% IPS (performance per clock) improvements.

Performance

The average 3750H in our database is in the same league as the Core i7-10610U, as far as multi-thread benchmark scores are concerned. This is a fairly good result, as of early 2022.

The ROG Zephyrus G15 GA502DU is among the fastest laptops built around the 3750H that we know of. It can be about 20% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

This Ryzen 7 has a default TDP of 35 W (also known as the long-term power limit). Laptop manufacturers are free to change that value to anything between 12 W and 35 W with clock speeds and performance changing accordingly. These values are comparatively high, making an active cooling solution pretty much a necessity.

Last but not the least, this AMD APU is built with a rather old, as of late 2022, 12 nm process for lower-than-average energy efficiency.

Intel Core i7-10700K

The Intel Core i7-10700K is a high-end desktop CPU based on the Comet Lake architecture. The CPU offers 8 cores and 16 threads clocked at 3.8 - 5.1 GHz. The TDP is rated at 125 Watt (PL1) but the PL2 is set to 229 Watt for short term boosts (up to 56 seconds).

Intel Core i9-10900K

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.
