Intel Core i9-13950HX vs Intel Core i7-9750H vs Intel Core i9-13900HX

Intel Core i9-13950HX

The Intel Core i9-13950HX is a fast high-end mobile processor of the Raptor Lake-HX series. Is was announced in early 2023 and is based on the desktop Core i9-13000K with combined 24 cores and 32 threads. Eight fast Raptor Cove performance cores (P-cores) clocked from 2.2 to 5.5 GHz (single core, all core boost 4.9 GHz) with HyperThreading and sixteen Gracemont efficiency cores without HyperThreading clocked from 1.6 to 4 GHz. The 13950HX is very similar to the Core i9-13980HX, but with vPro Enterprise support and a 100 MHz reduced boost of the P-cores.

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).

Performance

The average 13950HX in our database is in the same league as the i9-13980HX and the i9-13900HX while being noticeably faster than the Ryzen 9 7845HX, as far as multi-thread benchmark scores are concerned. This is a very, very fast chip, as of mid 2023.

Thanks to its powerful cooling solution and a long-term CPU power limit of 145 W, the MSI GE78HX 13VH-070US is among the fastest laptops built around the 13950HX that we know of.

Power consumption

The chip's "minimum assured" power consumption is 45 W while its Turbo power consumption isn't supposed to go over 157 W. Intel suggests the "base" power consumption should be set to 55 W, which laptop makers aren't really obliged to do. Most will go for a higher value to get better performance.

This i9 series processor is manufactured on Intel's 4th generation 10 nm process marketed as Intel 7 for average, as of early 2023, energy efficiency.

Intel Core i7-9750H

The Intel Core i7-9750H is a high-end processor for laptops with six cores based on the Coffee Lake architecture (2019 refresh, CFL-HR). The processor clocks at between 2.6 and 4.5 GHz (4 GHz with 6 cores) and can execute up to twelve threads simultaneously thanks to Hyper-Threading. According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process. Compared to the predecessor, the Core i7-8750H, the 9750H offers improved clock rates and a larger L3 cache.

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

Multi-thread performance is most comparable to the Intel Core i9-8950HK, an expensive hexa-core processor of the previous generation. While performance gains over the outgoing 8th Gen H-class chips are unimpressive to say the least, the average Core i7-9750H in our database is much faster than the Ryzen 7 3750H and other H-class Ryzen chips AMD sells as of mid 2019.

Thanks to its decent cooling solution and a long-term power limit of around 70 W, the Walmart EVOO Gaming 17 is among the fastest laptops powered by the 9750H that we know of. It can be 40% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Graphics

The integrated Intel UHD Graphics 630 is supposed to offer a slightly higher performance as its clock rate has been increased by 50 MHz compared to the UHD 630 of the 8750H CPU. 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

This Core i7 series chip has a default TDP (also known as the long-term power limit) of 45 W, a value that laptop makers are allowed to reduce slightly, 35 W being the lowest Intel-recommended value. Doing so would result in lower clock speeds and lower performance. Either way, a proper cooling solution is a must for a CPU like this.

The hexa-core Intel CPU is made with one of the old 14 nm Intel processes for below average, as of late 2022, energy efficiency.

Intel Core i9-13900HX

The Intel Core i9-13900HX is a fast high-end mobile processor of the Raptor Lake series. Is was announced in early 2023 and looks like it is based on the desktop Core i9-13000K with combined 24 cores and 32 threads. Eight fast Raptor Cove performance cores (P-cores) with HyperThreading that clock between 2.2 GHz (base) and 5.4 GHz (single core boost, 4.9 GHz for all cores) and sixteen Gracemont efficiency cores without Hyper-Threading (1.6 - 3.9 GHz).

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 13900HX).

Performance

The average 13900HX in our database is in the same league as the Core i9-13950HX and the Ryzen 9 7845HX, as far as multi-thread benchmark scores are concerned. This is really impressive, to say the least.

Thanks to its decent cooling solution and a long-term CPU power limit of 99 W, the Eluktronics Mech-17 GP2 is among the fastest laptops built around the 13900HX that we know of. It can be about 50% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

The CPU is still produced in a further improved 10nm FinFET process (Intel 7) that allows the higher clock speeds. The power consumption is specified at 55W base power up to 157 Watt max. Turbo power.
