Intel Core i7-7500U vs Intel Core i5-13500HX vs Intel Xeon E3-1505M v6

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 Xeon E3-1505M v6

The Intel Xeon E3-1505M v6 is a fast quad-core processor notebooks based on the Kaby Lake architecture and was announced in January 2017. It is the second fastest mobile Xeon model and the performance is slightly better tha the 100 MHz slower clocked consumer Core i7-7820HQ. Compared to the Core processors, the chip also supports ECC-RAM (error correction). Besides four cores including Hyper-Threading support running at 3 - 4 GHz (4 cores up to 3.6 GHz, 2 cores up to 3.8 GHz), the processor is also equipped with the professional HD Graphics P630 GPU as well as a dual-channel memory controller (DDR3L-1600/DDR4-2400). It is manufactured in a 14nm 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

Thanks to the higher clocks, even the smaller model of the mobile Xeons is ahead of the fastest Skylake models (Xeon E3-1575M v6) and is therefore als powerful enough for very demanding applications.

Graphics

The integrated professional Intel HD Graphics P630 has 24 Execution Units (similar to previous HD Graphics 530) running at 350 - 1100 MHz. The performance depends a lot on the memory configuration; it should be comparable to a dedicated Nvidia GeForce 920M in combination with fast DDR4-2133 dual-channel memory. It offers certified drivers for 15 professional and CAD applications.

Contrary to Skylake, Kaby Lake now supports hardware decoding for H.265/HEVC Main 10 with a 10-bit color depth as well as Google's VP9 codec. The dual-core Kaby Lake processors, which were announced in January, should also support HDCP 2.2.

Power Consumption

The chip is manufactured in an improved 14nm process with FinFET transistors, which improves the efficiency even further. Intel still specifies the TDP with 45 Watts, but it can also be reduced to 35 Watts by the notebook manufacturers (cTDP down). This will obviously affect the performance, because the Turbo Boost cannot be maintained for longer periods.
