The AMD Ryzen 3 7320U is a mobile processor for cheap laptops of the Mendocino series. It integrates four older Zen 2 cores (similar to the Ryzen 4000 series like the Ryzen 3 4300U). The CPU cores clock from 2.4 GHz (base) to 4.1 GHz (single core Turbo) and can use 4 MB L3 cache. Thanks to SMT/Hyperthreading, the CPU can work on 8 threads simultaneously. The integrated memory controller only supports fast LPDDR5 memory (5500 MHz max.). Compared to the fastest Mendocino model the Ryzen 5 7520U, the 7320U offers lower clocked CPU cores (400 MHz base, and 200 MHz Turbo).
The integrated graphics adapter (Radeon 610M iGPU) uses the modern RDNA 2 architecture, but only 2 CUs (128 shaders) and clocks with up to 1.9 GHz.
Performance
We have not tested a single system built around the 7320U, as of September 2023. Expect the chip to be about as fast as the Ryzen 3 3100 (four Zen 2 cores running up to 3.9 GHz).
Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solution of your laptop is.
Mendocino series chips are produced on a relatively modern 6nm FinFET process at TSMC and should offer a good power efficiency. The R3 7320U is rated at 8-15 W TDP and therefore well suited for thin and light laptops.
The Intel Core i5-7500 is a fast mid-range quad-core processor for desktops based on the Kaby Lake architecture and was announced in January 2017. It offers four cores (no HyperThreading and therefore also only 4 threads at once) that run at 3.4 - 3.8 GHz.
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
The performance of the i5-7500 is comparable to a mobile Core i7-7700HQ. Therefore, the performance is sufficient even for demanding applications and games.
Graphics
The integrated Intel HD Graphics 630 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.
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 slightly. Intel still specifies the TDP with 65 Watts, which is a lot more than the 45 Watts of the mobile Kaby-Lake-H CPUs but less than e.g. the Core i5-7600K (91 Watt).
The Intel Core i7-7700HQ is a fast quad-core processor for notebooks based on the Kaby Lake H architecture (7th generation Core), which was announced in January 2017 at CES. It is the successor to the Core i7-6700HQ from the Skylake generation and is manufactured in an improved 14 nm+ process, so the clocks are 200 MHz higher at the same TDP. The architecture was not changed, only the video engine got an update (see our Kaby Lake article).
The integrated graphics card is called Intel HD Graphics 630, but the architecture does not differ from the 530 GPU from the Skylake generation and only the clocks are slightly higher.
Performance
Thanks to the 200 MHz higher clocks (5.5-7.6% depending on the Boost), the CPU performance is increased and roughly on par with the Core i7-6970HQ (2.8-3.7 GHz but with 128 MB eDRAM). The TDP can also be reduced to 35 Watts (cTDP down), but this will reduce the performance.
Power Consumption
Due to its 45-Watt TDP, the CPU will be used in bigger notebooks with at least 15 inches most of the time.
