AMD Ryzen 5 7520U vs AMD Ryzen 3 7330U

AMD Ryzen 5 7520U

The AMD Ryzen 5 7520U 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 2.8 GHz (base) to 4.3 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.).

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

The average 7520U in our extensive database is in the same league as the Core i7-1185G7, as far as multi-thread benchmark scores are concerned. This is a so-so result and indicative of a lower mid-range chip, as of Q3 2023.

Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solution of your system is.

Mendocino series chips are produced on a relatively modern 6nm FinFET process at TSMC and should offer a good power efficiency. The R5 7520U is rated at 8-15 W TDP and therefore well suited for thin and light laptops.

AMD Ryzen 3 7330U

The AMD Ryzen 3 7330U is a processor for thin and light laptops based on the Cezanne generation. It is part of the second "Barcelo" refresh in early 2023 and offers 200 MHz higher clocked boost clock speed, but lower base clock speed compared to the old Ryzen 3 5425U. The R3 7330U integrates four of the eight cores based on the Zen 3 microarchitecture and is the slowest U-series processor of the Barcelo refresh at launch. The cores are clocked at 2.3 (guaranteed base clock) to 4.3 GHz (single core boost) and support SMT / Hyperthreading (8 threads). The chip is manufactured in 7 nm at TSMC.

The performance of the CPU part should be slightly better than the old Ryzen 3 5425U in the entry level. 

In addition to the four CPU cores, the APU also integrates a Radeon RX Vega 6 integrated graphics card (called Radeon Graphics) with 6 CUs and up to 1800 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 8 MB level 3 cache (same as the old 4800U) can be found on the chip.

Power consumption

This Ryzen 3 has a default TDP (also known as the long-term power limit) of 15 W and therefore also suited for thin and light laptops.
