AMD has been teasing its 7th generation Bristol Ridge APUs for quite a while now but we’re finally getting the full details on the company’s new system on a chip.
As expected, Bristol Ridge comes with four excavator cores and eight Radeon graphics cores. Some of the underlying improvements include HEVC support to help decode high-resolution video content, 128-bit support for DDR4 (or DDR3) memory and 12 lanes of PCI-e Gen3.
Despite these additions, Bristol Ridge has a lot in common with the sixth-generation Carrizo architecture. Both APU families share a similar, if improved, 28-nanometer process and the layout of the chip itself is almost identical.
However, what makes AMD’s 7th generation chip evolutionary is the way company is tuning each individual APU to perform at its absolute limits. For starters, Bristol Ridge’s compute cores perform 20% faster than Carrizo while offering up to 37% more GPU performance and 12% better energy efficiency.
To eke out this extra performance, AMD ran each chip through a reliability tracking test in which it would run the processor at higher temperatures to survey how far they could push the chip.
AMD also implemented a new Skin Temperature Aware Power Management that basically means it is …read more
