AMD announced its 7th Generations of Bristol Ridge APUs, which is based on Excavator core and features the same GCN 1.2 version that powers the Fury cards, it is built on 28nm HKMG based.
The first wave of Bristol Ridge chips is aimed at the mobile market. The mobile parts are rated at 15 watts to 35 watts. But those how in desktop, have to wait as AMD is not announcing Bristol Ridge for the AM4 platform and higher TDPs.
The base level Bristol Ridge comprised of two Excavator modules (4 cores), eight GCN cores (512 stream units), and an integrated south bridge with a 124-bit DDR3/DDR4 memory controller with speeds up to DDR4-2400 and only 12 PCI-E 3.0 lanes. The Bristol Ridge also has AMD’s second HSA 1.0 compliant part and latest UVD 6.0 unit which has VP9 and H.265/HEVC support.
The FX, A12, and A10 APUs are positioned for the midrange and higher end laptop market. These will include 15 and 35-watt parts that have the most aggressive clocks and support for DDR4-2400 memory. The A9, A6, and E2 APUs are positioned for the entry and lower midrange markets with support for up to DDR4-2133 memory.
Bristol Ridge improves upon CPU performance by around 15% over Carrizo, around 30% in graphics performance, and cuts down power consumption in multimedia playback and productivity apps by around 10%.
