AMD Ryzen 3 2300U vs AMD Ryzen 7 2800H

AMD Ryzen 3 2300U

The AMD Ryzen 3 2300U is a mobile APU for thin and light laptops that was announced in October 2017. It includes four Zen cores clocked at 2 to 3.4 GHz and offers no SMT (four threads) and 4 MB L3-Cache. The integrated graphics card is called Radeon RX Vega 6 and offers 6 CUs (384 Shaders) clocked at up to 1100 MHz. The TDP is configurable between 12 and 25 Watt (15 Watt nominal).

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.

Performance

While we have not tested a single system built around the 2800H as of August 2023, it's safe to expect the chip to be 10% to 15% faster than Ryzen 3 1200, as far as multi-thread performance is concerned.

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

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.
