The Integrated GPU

For all but one of the processors, integrated graphics is the name of the game. AMD configures the integrated graphics in terms of Compute Units (CUs), with each CU having 64 streaming processors (SPs) using GCN 1.3 (aka GCN 3.0) architecture, the same architecture as found in AMD’s R9 Fury line of GPUs. The lowest processor in the stack, the A6-9500E, will have four CUs for 256 SPs, and the A12 APUs will have eight CUs, for 512 SPs. The other processors will have six CUs for 384 SPs, and in each circumstance the higher TDP processor typically has the higher base and turbo frequency.

A12-9800 Radeon R7 512 800 1108 65W
A12-9800E Radeon R7 512 655 900 35W
A10-9700 Radeon R7 384 720 1029 65W
A10-9700E Radeon R7 384 600 847 35W
A8-9600 Radeon R7 384 655 900 65W
A6-9500 Radeon R5 384 720 1029 65W
A6-9500E Radeon R5 256 576 800 35W
Athlon X4 950 - - - - 65W

The new top frequency, 1108 MHz, for the A12-9800 is an interesting element in the discussion. Compared to the previous A10-7890K, we have a +28% increase in raw GPU frequency with the same number of streaming processors, but a lower TDP. This means one of two things – either the 1108 MHz frequency mode is a rare turbo state as the TDP has to be shared between the CPU and APU, or the silicon is sufficient enough to maintain a 28% higher frequency with ease. Obviously, based on the overclocking results seen previously, it might be interesting to see how the GPU might change in frequency without a TDP barrier and with sufficient cooling. For comparison, when we tested the A10-7890K in Grand Theft Auto at a 1280x720 resolution and low-quality settings, we saw an average 55.20 FPS.

Bearing in mind the change in the cache configuration moving to Bristol Ridge, moving from a 4 MB L2 to a 2 MB L2 but increasing the DRAM compatibility from DDR3-2133 to DDR4-2400, that value should move positive, and distinctly the most cost effective part for gaming.

Each of these processors supports the following display modes:

- DVI, 1920x1200 at 60 Hz
- DisplayPort 1.2a, 4096x2160 at 60 Hz (FreeSync supported)
- HDMI 2.0, 4096x2160 at 60 Hz
- eDP, 2560x1600 at 60 Hz

Technically the processor will support three displays, with any mix of the above. Analog video via VGA can be supported by a DP-to-VGA converter chip on the motherboard or via an external dongle.

For codec support, Bristol Ridge can do the following (natively unless specified):

- MPEG2 Main Profile at High Level (IDCT/VLD)
- MPEG4 Part 2 Advanced Simple Profile at Level 5
- MJPEG 1080p at 60 FPS
- VC1 Simple and Main Profile at High Level (VLD), Advanced Profile at Level 3 (VLD)
- H.264 Constrained Baseline/Main/High/Stereo High Profile at Level 5.2
- HEVC 8-bit Main Profile Decode Only at Level 5.2
- VP9 decode is a hybrid solution via the driver, using CPU and GPU

AMD still continues to support HSA and the arrangement between the Excavator v2 modules in Bristol Ridge and the GCN graphics inside is no different – we still get Full 1.0 specification support. With the added performance, AMD is claiming equal scores for the A12-9800 on PCMark 8 Home with OpenCL acceleration as a Core i5-6500 ($192 tray price), and the A12-9800E is listed as a 17% increase in performance over the i5-6500T. With synthetic gaming benchmarks, AMD is claiming 90-100% better performance for the A12 over the i5 competition.

    I want to see an AMD A10 vs Apple A10 article. Reply
  • goatfajitas - Friday, September 23, 2016 - link

    Why? AMD is an x86 processors that can run Windows and complete systems. Apple is an ARM processor that runs nice toys. They are not in the same ballpark. Reply

    Universal Windows apps can run on ARM. Reply

    All three of them, but don't expect even them to work until tested. Reply

    Update your mantra, it smells. Reply

    OK, but that isnt really the point. Comparing ARM to x86 is like comparing a sports car to an 18 wheel truck. Both are good, both have their purpose, but they aren't really in the same market segments. Are is great at specific things, where x86 is the workhorse of the industry. Reply

    Generalizing like that is quite foolish, atom is x86, but it is closer to a wheelchair than an 18 wheeler.

    From what I can tell, the apple's A10 is about the same performance as premium mobile device x86 chips from intel. The fact that it has no serious programs for it and doesn't allow you to run even your own programs without jailbreaking ... is a whole different topic.

    Performance is one metric, usability - another metric. And sure, performance without usability is a shame, but that's what the corporations dictate - those aren't devices for you to use as much as they are devices for you to be used.

    Do you think anyone actually cares about your sense of superiority over mobile app users? Reply

    I don't care what anyone cares about, their biz, not mine. Reply

    Using that ideology let's just say many people don't like your strong opinions projected upon them, either. Reply
