AMD Ryzen 5 2400G vs AMD Ryzen 7 2800H

AMD Ryzen 5 2400G

The AMD Ryzen 5 2400G is a desktop APU that was announced in early 2018. It is the fastest Raven Ridge APU at that time and features all four Zen cores (8 threads due to SMT support) clocked at 3.6 - 3.9 GHz with a Radeon RX Vega 11 graphics card with 11 CUs (all of the 704 Shaders on the chip) clocked at up to 1250 MHz. The integrated dual-channel memory controller supports up to DDR-2933. The TDP is specified at 65 Watt and the CPU, GPU and memory are unlocked for overclocking.

AMD Ryzen 7 2800H

The AMD Ryzen 7 2800H is a mobile SoC that was announced late 2018. It is intended for mid-sized to big laptops and combines four Zen cores (8 threads) clocked at 3.3 (base) - 3.8 GHz (boost) with a Radeon RX Vega 11 Mobile graphics card with 11 CUs (704 Shaders). The integrated dual-channel memory controller supports up to DDR4-3200 memory.

Compared to the older Ryzen 7 2700U for slim and light laptops, the 2800H offers a higher TDP (45 Watt versus 15 Watt), higher clocked memory, a higher base clock (3.4 versus 2.2 GHz), and a faster integrated GPU.

The performance should be slightly better than the Ryzen 7 2700U due to the higher TDP and base clock speed. Especially longer loads should profit from this. Due to the high TDP (configurable from 35 - 54 Watt), the Ryzen 7 2800H is best suited for bigger laptops.

Power consumption

This Ryzen 7 has a default TDP (also known as the long-term power limit) of 45 W, a value that laptop manufacturers are free to change to anything between 35 W and 54 W with clock speeds and performance changing correspondingly. All the values are rather high, making a high-performance cooling solution with two or three fans pretty much a necessity.

The CPU is built on an old, as of late 2022, 14 nm process for subpar energy efficiency.
