AMD’s Flagship Bristol Ridge-based APU to Feature 16 CUs, Even Faster than Xbox One
With AMD’s next gen CPU architecture just around the corner of unveiling, the tech rumor mill is following the chipmaker’s each and every move. According to a new report from Bits and Chips, AMD is planning to launch an insanely powerful APU under their Bristol Ridge family, which will be just as fast as the Xbox One.
The report alleges that the flagship Bristol Ridge-based APU is based on the GCN 3.0 architecture and would feature 16 compute units (CUs), coupled with 1024 stream processors. Since the specific APU will pack double the CUs that we have seen in the current Kaveri- and Godavari-based APUs, it would be considerably more powerful than the latter.
Although 16 CUs appear to be almost impossible on an APU that is built on 28nm process, still if AMD could achieve this feat, it will pack a serious punch at consoles.
AMD Bristol Ridge APU Family and SKUs
The entire Bristol Ridge family will be featured on the exciting AM4 platform, which supports dual-channel DDR4 – offering 50GB/sec of bandwidth. According to the slides leaked back in December last year, the Bristol Ridge APU family is known as the AMD Family 15h Models 65h-6Fh (BKDG and Electrical Datasheet) that will replace the Carrizo APUs on mobile front and Godavari APUs on desktop front.
The upcoming APU family will pack 8 SKUs, out of which seven SKUs are based on a quad core design while one chip retains a dual core design. The AM4 APUs will utilize a new branding scheme, most probably A-Series 9000, with clock speeds ranging from 2.5 to 3.6 GHz base and 2.8 to 4.0 GHz boost clocks.
On the desktop front, there will be AM4 platform which includes the x86 Excavator based Bristol Ridge APUs for mainstream desktop systems and the Zen based Summit Ridge processors for enthusiast grade desktop systems.
Bristol Ridge OPNs With Higher Base Clock Speeds
Recently, we reported about new mobile Bristol Ridge OPNs that would apparently jump by one thousand from Carrizo’s, with an additional thirty points for the 35W variants. The TDP ranges got split into 15W and 35W while the CPU base clocks also jump significantly.
This performance improvement over Carrizo family of APUs is the result of AMD engineers “applying more aggressive power management to the 28nm design,” the US-based chipmaker said at ISSCC 2016. “The Bristol Ridge design was a study in using power management to overcome performance limits tied to heat, voltage and current.”
AMD is expected to launch Bristol Ridge APUs at 2016 Computex in June.
