Intel Core i5-10400F vs Intel Core i5-11400F
Intel Core i5-10400F
► remove from comparison
The Intel Core i5-10400F is a mid-range processor for desktops with six cores based on the Comet Lake architecture (CML-S, 4th generation of Skylake). The processor clocks at between 2.9 and 4.3 GHz and can execute up to 12 threads simultaneously thanks to Hyper-Threading.
The processor is still manufactured on the old 14nm (14nm++) process.
The Comet Lake architecture is similar to Coffee Lake and offers the same features and is made with the same 14 nm process. Other than the improved clock rates, the memory controller now also supports faster DDR4-2666 RAM. More information on Comet Lake and all the models and articles on it can be found here.
Performance
The average 10400F in our database matches the Ryzen 7 4800U and also the Core i7-9700K in multi-thread performance to be a more than decent mid-range option for your gaming rig, as of early 2022.
Graphics
The CPUs with an "F" suffix do not feature an integrated graphics adapter. The Intel UHD Graphics 630 iGPU is deactivated.
Power consumption
This Core i5 has a default TDP (also known as the long-term power limit) of 65 W which is in line with most desktop chips.
The i5-10400F is built with one of the old 14 nm Intel processes for poor, as of mid 2023, energy efficiency.
Intel Core i5-11400F
► remove from comparison
The Intel Core i5-11400F is a fast six-core desktop processor based on the new Rocket Lake architecture, which was introduced in March 2021. The processor clocks with a base clock of 2.6 GHz and reaches an all-core boost of 4.2 GHz under load. In single-thread applications, the Intel Core i5-11400F even reaches up to 4.4 GHz. Intel also gives the Rocket Lake processors the Hyperthreading feature, which allows the i5-11400F to process up to 12 threads simultaneously. As known, the Intel Core i5-11400F is manufactured in the 14 nm process. Nevertheless, many changes have been made with the Rocket Lake architecture, which is also reflected in the performance compared to the Comet Lake. The Intel Core i5-11400F is a non-K CPU, which means that there is no freely selectable multiplier. Thus, the scope for overclocking is relatively small.
Performance
Compared to the Intel Core i5-10400F, the Core i5-11400F offers a significantly better IPC. This can be seen clearly in the single-core benchmarks. But the multi-core performance also benefits from the better IPC compared to Comet-Lake. A performance increase of up to 20 percent can be expected. The Core i5 has to do without the TVB (Thermal Velocity Boost). However, 4.2 GHz is still possible when all cores are loaded. Due to the very high single-thread performance, the Intel Core i5-11400F is best suited for video games.
Graphics
The processors marked with "F" in the nomenclature don't offer an integrated graphics unit. All other non-F processors can fall back on the Intel UHD Graphics 750 and also allow operation without a dedicated graphics card.
Power consumption
The TDP turns out relatively low with 65 watts. This is the PL1 value. For Turbo, the Intel Core i5-11400F offers a higher TDP of up to 154 watts with PL2. However, this may only be applied for a maximum of 28 seconds (dew). A good air cooler should be able to handle the resulting waste heat, so no AiO is necessary for this processor.
