HP EliteBook 745 G3 (FHD) Notebook Review
AMD Pro A12-8800B | AMD Radeon R7 (Carrizo) | 14.00" | 1.6 kg
The AMD Pro A12-8800B is the top-tier Carrizo APU of 2015 for business 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). It is similar to the consumer version, the FX-8800P, but offers business support and a ensure a long-tail support program.
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 (based on the similar FX-8800P).
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. See more benchmarks on our FX-8800P page.
More technical details and features of the 6th generation of APUs (Carrizo) can be found in our launch article.
