Intel Core i5-14501E vs Intel Core i9-9980HK vs Intel Core i5-8400H

Intel Core i5-14501E

The Intel Core i5-14501E is a peculiar Raptor Lake family desktop processor (SoC) that has 6 performance cores but 0 efficient cores. It's the lack of E-cores that makes 14X01 chips special.

The product has decently sized level 2 and 3 caches at 12 MB and 24 MB, respectively. Its CPU cores run at up to 5.2 GHz. The UHD 770 serves as the integrated graphics solution. There is no 'proper' NPU here, however, vPro Enterprise features such as RPE (Remote Platform Erase) are onboard.

The i5 chip is manufactured built with the Intel 7 process which is fairly old, as of mid 2025. Its base TDP sits at 65 W which is the standard value for desktop CPUs.

Performance

While we have not tested a single 14X01 processor as of July 2025, we do know that a single 4.6 GHz Raptor Cove core, such as that of an Core i7-14650HX is good for 116 Cinebench 2024 points and 285 Cinebench R15 points. (The 14501E can run at up to 5.2 GHz, too, to remind you.) If we multiply the values by 6, we get a reasonably fair projection that sees the 14501E being about as fast as lower mid-range laptop AMD chips of 2025, such as the AMD Ryzen AI 5 340. While not particularly impressive, this is definitely sufficient for any tasks and applications one could run in 2025, top games included.

Intel Core i9-9980HK

The Intel Core i9-9980HK is a high-end processor for laptops with eight cores based on the Coffee Lake architecture (2019 refresh, CFL-HR). The processor clocks at between 2.4 - 5 GHz and can execute up to sixteen threads simultaneously thanks to Hyper-Threading. The 5 GHz can only be reached using the "Thermal Velocity Boost" which allows one core to boost to 5 GHz (+100 MHz) as long as the CPU temperature is below 50°C. Multiple cores can be boosted +100 MHz? below 50°C (not verified). Compared to the predecessor, the Core i9-8950HK, the 9980H is based on the same architecture but offers 2 more cores and higher clock speeds (boost).

According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process. The i9-9980HK is the fastest model of the Coffee-Lake-H (refresh) series at the time of announcement and offers an unlocked multiplier for overclocking of the CPU.

The Coffee Lake architecture is similar to Kaby Lake and differs only in the amount of cores (now max. eight cores for the high end versions) and the improved 14nm process (14nm++ according to Intel).

Performance

Due to the two additional cores, performance has increased by almost 33% compared to a similar clocked 6-core processor. According to first benchmarks, the mobile variant can reach the performance of the Core i9-9900K if the cooling is sufficient.

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. 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 i9 is only suited for big laptops with good cooling solutions.

Intel Core i5-8400H

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.
