Intel Core i7-13850HX vs Intel Core i5-11400F
Intel Core i7-13850HX
► remove from comparison
The Intel Core i7-13850HX is a fast high-end mobile processor of the Raptor Lake series. Is was announced in early 2023 and offers combined 20 cores and 28 threads. Eight fast Raptor Cove performance cores (P-cores) with Hyper-Threading and eight Gracemont efficiency cores without HyperThreading. The 13850HX supports the full enterprise set of vPro management features.
The eight P-Cores are clocked from 2.1 GHz (base) up to 5.3 GHz (single core boost, all cores up to 4.7 GHz). The twelfe E-Cores clock between 1.5 (base) and 3.8 GHz (boost).
Compared to Alder Lake, Raptor Lake offers improved P-Cores (Raptor Cove micro-architecture) with bigger Caches and more E-Cores (same Gracemont micro-architecture). Furthermore, the chip supports faster DDR5 memory (up to 5600 MHz for the 13850HX).
Performance
While we have not tested a single system built around the 13850HX as of August 2023, we fully expect the chip to be at least a couple pecentage points faster than the i9-12900HX, a CPU featuring eight P-cores and eight E-cores that run at nearly the same clock speeds as what the 13850HX has. Just how wide the performance delta will be will depend a lot on how competent the laptop's cooling solution is, and how high the CPU power limits are.
Power consumption
The chip's "minimum assured" power consumption sits at 45 W. Its Intel-recommended "Maximum Turbo" power consumption is 157 W while the Base power consumption is supposed to be around 55 W. Most laptop makers will probably go for a value much higher than 55 W to extract as much performance out of the chip as possible.
This Core i7 series processor is built with Intel's 4th generation 10 nm process marketed as Intel 7 for average, as of early 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.
