Intel Core i5-13600HX vs Intel Core i5-8400H
Intel Core i5-13600HX
► remove from comparison
The Intel Core i5-13600HX is a fast mid-range mobile processor of the Raptor Lake series. Is was announced in early 2023 and integrates 6 fast Raptor Cove performance cores (P-cores) with HyperThreading and 8 Gracemont efficiency cores without HyperThreading. The P-Cores clock between 2.6 GHz (base) up to 4.8 GHz (single core boost, all-core 4.5 GHz). The smaller E-Cores clock between 1.9 and 3.6 GHz. All cores can access the combined 24 MB L3 cache. The CPU supports vPro (Enterprise) management features.
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 13980HX, but only 4800 MHz for the i5).
Performance
While we have not tested a single system built around the 13600HX as of August 2023, we have plenty of performance data for the i7-13650HX, a chip with almost the same specs (six P-cores mated to eight E-cores, with the latter running at the same clock speeds as what the 13600HX has and the former running at up to 100 MHz faster which is a very small difference). Based on that, we expect the 13600HX to be just a few percentage points behind the i7-13700HX and the i9-12950HX, meaning it's a very, very fast CPU, as of mid 2023.
Your mileage may vary depending on how competent the cooling solution of your laptop is, and how high the CPU power limits are.
Power consumption
The chip's "minimum assured" power consumption sits at 45 W. Its peak Turbo power consumption is not supposed to go over 157 W and its Intel-recommended Base power consumption is 55 W. Most laptop makers will probably go for a noticeably higher value to get better performance.
The i5-13600HX is built with Intel's 4th generation 10 nm process marketed as Intel 7 for average, as of early 2023, energy efficiency.
Intel Core i5-8400H
► remove from comparison
The Intel Core i5-8400H is a high-end processor for laptops with four cores based on the Coffee Lake architecture and will be announced early 2018. The processor clocks at between 2.5 and 4.2 GHz (4.1 with 4 cores) and can execute up to eight threads simultaneously thanks to Hyper-Threading. According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process.
The Coffee Lake architecture is similar to Kaby Lake and differs only in the amount of cores (now six cores for the high end versions) and the improved 14nm process (14nm++ according to Intel).
Performance
The Intel Core i5-8400H should perform similar as the older Core i7-7920HQ (3.1 - 4.1 GHz). The faster Coffee Lake CPUs, like the Core i7-8750H offers two additional cores and is therefore up to 50% faster in multithreaded benchmarks. Still, the performance of the i5-8400H should be sufficient for even demanding applications and games.
Graphics
The integrated Intel UHD Graphics 630 iGPU is supposed to offer a slightly higher performance as its clock rate has been increased by 50 MHz (rumored). The architecture is identical to that of the Intel HD Graphics 630. We do expect a performance improvement, but as a low-end solution it will probably only display current games smoothly at reduced details - if at all.
Power Consumption
Intel specifies the TDP with 45 watts and therefore the i5 is only suited for big laptops with good cooling solutions. Using cTDP-down, the CPU can also be configured to 35 Watt resulting in a reduced performance.
