AMD releases new line-up of 7th generation APUs: Bristol Ridge and Stoney Ridge APUs
AMD releases new line-up of 7th generation APUs
AMD announced its entire line-up of 7th generation AMD APUs (Accelerated Processing Units) today. Previously codenamed "Bristol Ridge" and "Stoney Ridge", the new processors introduced into the AMD FX, A-series and E-series line-up promises to improve computing performance when compared to previous generation, whether in games, video rendering or file compression.
In a nutshell, the 7th generation APUs are largely based on their 6th generation Carrizo APU counterparts with the same Excavator processor core utilized and thus based on the same 28nm Bulk CMOS process technology. Even the graphics engine is mostly intact from what debuted on Carrizo - Up to Radeon R7 class graphics based on the GCN 1.2 architecture with up to 8 CUs and 512 shader processors.
So what has changed? Broadly speaking, tweaks to the manufacturing process technology along with a new AVFS (adaptive voltage frequency scaling) algorithm has helped the 7th Gen APU to ramp up clocks to offer higher frequency parts at the same TDP when compared to previous APU generations. The APU has also hopped on the DDR4 bandwagaon and sports and updated UVD block.
Below is the list of all 7th generation AMD APUs announced today:-
|7th Gen APU Model||Radeon Brand||TDP||Max / Base CPU Frequency|
|AMD FX 9830P||Radeon R7 Graphics||35W
|3.7GHz / 3.0GHz|
|AMD FX 9800P||Radeon R7 Graphics||15W
|3.6GHz / 2.7GHz|
|AMD A12-9730P||Radeon R7 Graphics||35W
|3.5GHz / 2.8GHz|
|AMD A12-9700P||Radeon R7 Graphics||15W
|3.4GHz / 2.5GHz|
|AMD A10-9630P||Radeon R5 Graphics||35W
|3.3GHz / 2.6GHz|
|AMD A10-9600P||Radeon R5 Graphics||15W
|3.3GHz / 2.4GHz|
|AMD A9-9410||Radeon R5 Graphics||15W
|3.5GHz / 2.9GHz|
|AMD A6-9210||Radeon R4 Graphics||15W
|2.8GHz / 2.4GHz|
|AMD E2-9010||Radeon R2 Graphics||15W
|2.2GHz / 2.0GHz|
The new AMD FX, A12 and A10 APUs (part of the Bristol Ridge family and identified with the "P" in their SKU naming) will come with DDR4 memory support for up to speeds of 2400MHz while the A9, A6 and E2 APUs (part of the Stoney Ridge family) will support DDR4 memory up to 2133MHz.
All of the latest processors will support hardware decode of UHD 4K H.264 content, which is an improvement over Carrizo where only the better tier APUs support this level of video decode performance. While Carrizo's UVD block is already plenty powerful, AMD has enhanced that further on the 7th Gen APUs to now claim 4K HEVC/H.265 hardware decode capability, but each series will have varying level of decode support for this codec. The graphics and video features of each series are detailed in the table below:-
|Technology||AMD FX||AMD A12||AMD A10||AMD A9||AMD A6||AMD E2|
|Vulkan and DirectX 12 with Multiadapter Support||X|
|Frame Rate Target Control||X||X|
|AMD Eyefinity Technology||X||X|
|AMD Dual Graphics||X||X||X|
|AMD Gaming Evolved Client Real-time Record and Play||X||X||X|

In terms of performance, AMD claims that it's able to achieve up to 50% general compute performance improvements over its 2-year old "Kaveri" APU. The GPU performance is also looking healthy, with as much as 37% improvement over the previous generation for the AMD FX series. In addition to performance gains, power consumption is also going to be lower with the "Bristol Ridge" with as much as 12% lower power consumption.
According to AMD, the latest 7th generation processors will require a change of the motherboard due to its support for newer DDR4 memory DIMMs. This is bad news for those planning to only perform an APU upgrade on their current system.
On the mobile front, these new APUs will also be found in some of the latest OEMs including brands like HP, Dell, Lenovo, Acer and ASUS.
