AMD Ryzen 3 7320U vs Intel Core i5-7500T vs Intel Pentium Gold 4410Y

AMD Ryzen 3 7320U

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.

Intel Core i5-7500T

The Intel Core i5-7500T is a power efficient desktop quad-core based on the Kaby Lake architecture. It was announced early 2017 and offers four cores and no HyperThreading (only 4 threads). The CPU clocks between 2.7 and 3.3 GHz. The integrated Intel HD Graphics 630 graphics card offers 24 EUs clocked at 350 to 1100 MHz. The TDP is specified at only 35 Watt and therefore even lower than mobile HQ quad cores (45 Watt). Thats why the CPU is also used in some laptops.

Intel Pentium Gold 4410Y

The Intel Pentium 4410Y is a low power entry level processor for small laptops or tablets and based on the Kaby Lake architecture. It was announced in Q2 2017 and offers two processor cores clocked at 1.5 GHz (no Turbo Boost). Thanks to Hyper Threading, the processor can execute up to four threads simultaneously. The chips also includes the Intel HD Graphics 615 GPU, a dual-channel memory controller (DDR3L/LPDDR3) as well as VP9 and H.265 video de- and encoder. It is still produced in a 14 nm process with FinFET transistors. Compared to the much faster Core m3-7Y30, the Pentium 4410 offers no Turbo Boost, different CPU and GPU clock speeds, a smaller L3 cache and a higher TDP of 6 Watt.

Architecture

Intel basically used the familiar micro architecture from the Skylake generation, so the per-MHz performance is identical. Only the Speed-Shift technology for faster dynamic adjustments of the voltages and clocks was improved, and the matured 14 nm process now also enables much higher frequencies and better efficiency than before. 

Performance

Due to the missing Turbo Boost, the Pentium 4410Y offers a significantly worse single thread performance than the more expensive Core m3-7Y30. This should be noticeable in daily tasks. The similar Pentium 4415Y is slightly faster due to the 100 MHz higher core clock of the processor cores.

Graphics

The integrated Intel HD Graphics 615 GPU has 24 Execution Units (EUs) like the old HD Graphics 515 and runs with clocks between 300 and 850 MHz in combination with this processor. The performance heavily depends on the TDP limit as well as the memory configuration; with fast LPDDR3-1866 RAM in dual-channel mode, the GPU should sometimes be able to compete with the HD Graphics 520, but can also be much slower in other scenarios. Modern games from 2016 will, if at all, only run smoothly in the lowest settings.

Contrary to Skylake, Kaby Lake now also supports hardware decoding for H.265/HEVC Main10 with a 10-bit color depth as well as Google's VP9 codec.

Power Consumption

The chip is manufactured in an improved 14 nm process with FinFET transistors, so the power efficiency was once again improved significantly. The TDP is rated at 6 Watt and can be reduced to 4,5 Watt (cTDP down).
