Intel Core i7-7500U vs Intel Core i5-13500HX vs Intel Core i9-13900HX

Intel Core i7-7500U

The Intel Core i7-7500U is a dual-core processor of the Kaby Lake architecture. It offers two CPU cores clocked at 2.7 - 3.5 GHz and integrates HyperThreading to work with up to 4 threads at once. The architectural differences are rather small compared to the Skylake generation, therefore the performance per MHz is very similar. The SoC includes a dual channel DDR4 memory controller and Intel HD Graphics 620 graphics card (clocked at 300 - 1050 MHz). It is manufactured in an improved 14nm FinFET process (14nm+) at Intel. Compared to the old Skylake Core i7-6500U (2.5 - 3.1 GHz), the i7-7500U clock speed is up to 400 MHz higher.

Intel Core i5-13500HX

The Intel Core i5-13500HX 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 Hyper-Threading. The P-Cores clock between 2.5 GHz (base) up to 4.7 GHz (single core boost, all-core 4.5 GHz). The smaller E-Cores clock between 1.8 and 3.5 GHz. All cores can access the combined 24 MB L3 cache.

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

The average 13500HX in our database is in the same league as the Ryzen 7 7745HX, Core i7-13705H, Core i9-12900HK, Core i9-13900H, Core i9-13905H, as far as multi-thread benchmark scores are concerned. This is 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 maximum Intel-recommended Turbo power consumption is 157 W and the Base power consumption is supposed to be around 55 W. Most laptop makers will go for a value much higher than 55 W to get better performance.

The i5-13500HX is manufactured on Intel's 4th generation 10 nm process marketed as Intel 7 for average, as of early 2023, 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.
