AMD Ryzen 7 2800H vs AMD FX-8800P

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.

AMD FX-8800P

The AMD FX-8800P is the top-tier Carrizo APU of 2015 for mainstream laptops. It is a SoC containing two Excavator CPU modules (with 4 integer and 2 FP units counted as 4 compute cores), a Radeon R7 graphics card with 8 compute cores (512 shaders), a DDR3-2133 (35 Watt cTDP) memory controller and a video engine (including UVD 6 with hardware HEVC / H.265 decoding).

The performances of the CPU and GPU cores depend on the configurable TDP. This cTDP can range from 12 to 35 Watts depending on the cooling solution and size of the laptop. Thus, clock speeds of the compute cores will vary. E.g., the GPU can score between 1992 points (15 Watts) to 2753 points (+38% with 35 Watts cTDP) in 3DMark 11 (P).

According to AMD, the 35 Watt configuration scores 12% (Cinebench single-thread) and 15% (Cinebench Multi-threaded) higher compared to the previous Steamroller generation (most likely the AMD FX-7600P). If configured to 15 Watt instead, the gains are higher (40% to 55%) compared to the 19 Watt Kaveri FX-7500 APU.
