Leaked Mapping Shows More AMD Bristol Ridge OPNs With Higher Base Clock Speeds
AMD’s upcoming Bristol Ridge family of APUs is set to replace the Carrizo APUs on mobile front and Godavari APUs on desktop front. Back in December last year, we reported that Bristol Ridge is known as the AMD Family 15h Models 65h-6Fh (BKDG and Electrical Datasheet) and will launch first for the AM4 and FP4 platforms.
So the FP4 will be the first mobile platform from AMD which supports DDR4 memory standard, while being compatible with current generation Carrizo and next generation Bristol Ridge and Stoney Ridge APUs.
More details about new mobile Bristol Ridge OPNs have now surfaced via Usb.org. Dresdenboy of The New Citavia Blog put this together with previous info, and using the the mobile Carrizo OPNs has created a mapping which represents what AMD is going to release as mobile Bristol Ridge chips for the FP4 socket sometime this year.
From the above table, model numbers 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. The new A-Series 9000 features clock speeds ranging from 2.5 to 3.6 GHz base and 2.8 to 4.0 GHz boost clocks.
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.”
As for the desktop part, the Bristol Ridge AM4 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 platform includes the x86 Excavator based Bristol Ridge APUs for mainstream desktop systems and the Zen based Summit Ridge processors for enthusiast grade desktop systems.
AMD is expected to launch Bristol Ridge APUs in the first half of 2016. By the time, users will have a range of AM4 motherboard options for their new processors.
