AMD Ryzen 3 7320U vs AMD Ryzen Embedded R1606G vs AMD Ryzen Embedded V1605B

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.

AMD Ryzen Embedded R1606G

The AMD Ryzen Embedded R1606G is a dual-core SoC designed for embedded systems that was announced in March 2019. It is similar to the Ryzen 3 3200U (or the 2200U with slightly increased clock speed) and based on the first generation of the Zen architecture. The Ryzen features two Zen cores with support for the thread-doubling SMT tech, clocked at 2.6 GHz - 3.5 GHz. The built-in Radeon RX Vega 3 iGPU has 3 CUs (192 unified shaders) clocked at up to 1,200 MHz. The default TDP is 15 W which makes the Ryzen a good fit for thin mid-range laptops.

In comparison to the faster Ryzen 3000 CPUs, the 3200U and therefore the R1606G is not using the newer Zen+ microarchitecture and is still manufactured in 14nm. Compared to the old Ryzen 3 2200U, the 3200U and R1606G therefore only offers a 100 MHz higher clock speed.

The R1606G is compatible with single-channel or dual-channel DDR4-2400 RAM. Please go to our Raven Ridge launch article for details on the architecture and more.

AMD Ryzen Embedded V1605B

The AMD Ryzen Embedded V1605B is an embedded APU for mini PCs and embedded solutions that was announced in February 2017. Compared to the similar consumer Ryzen 5 2500U, the V1605B offers different support and availability options.

It includes four Zen cores clocked at 2 to 3.6 GHz and offers 4 MB L3-Cache. The integrated graphics card is called Radeon RX Vega 8 and offers 8 CUs (512 Shaders) clocked at up to 1100 MHz. The TDP is configurable between 12 and 25 Watt (15 Watt nominal). More information on Raven Ridge can be found in our launch article.
