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.
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).
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.
The Intel Celeron 3965U is an ULV (ultra low voltage) dual-core SoC based on the Kaby-Lake architecture and has been launched in the first quarter of 2017. The CPU can be found in ultrabooks as well as normal notebooks. In addition to two CPU cores without Hyper-Threading clocked at 2.2 GHz (no Turbo Boost), the chip also integrates an HD Graphics 610 GPU and a dual-channel DDR4-2133/DDR3L-1600 memory controller. The SoC is manufactured using a 14 nm process with FinFET transistors.
Architecture
Intel basically uses the same micro architecture compared to Skylake, so the per-MHz performance does not differ. The manufacturer only reworked the Speed Shift technology for faster dynamic adjustments of voltages and clocks, and the improved 14nm process allows much higher frequencies combined with better efficiency than before.
Performance
Due to the missing Turbo Boost and the low clock speeds, especially the single thread performance is very limited which results in a lower performance even for lower demanding tasks. The performance should be between the Intel Pentium 4405U and 4415U. Still, the CPU has sufficient power for office and multimedia purposes.
Graphics
The integrated graphics unit called HD Graphics 610 (similar to the HD Graphics 510) represents the "GT1" version of the Kaby Lake GPU (Intel Gen. 9). Its 12 Execution Units, also called EUs, are clocked at 300 - 900 MHz and offer a performance somewhat below the older HD Graphics 4400. Only a few games of 2015 can be played smoothly in lowest settings.
Power Consumption
Specified at a TDP of 15 W (including CPU, GPU and memory controller), the CPU is best suited for small notebooks and ultrabooks (11-inches and above). Optionally, the TDP can be lowered to 10 watts (cTDP down), reducing both heat dissipation and performance and allowing even more compact designs.
