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.

    Actual evidence points to GF.

    Look at the photo of the chip-

    'Diffused in Germany' means the chip itself was made at GF in Dresden. Then shipped to Malaysia for packaging. Unless the photo is fake. Which is unlikely.

    Wondering if I understood correctly -- is video card slot limited to 8 lanes? If so, how will this affect APU with video card as primary, APU with video card in dual graphics, and Athlon x4 CPU with video card?

    Mr Cutress, we are one month later, where is the Bristol Ridge hardware? It would seem easier to reach out to Costco than AMD and have the platform tested. Where are you guys with that?

    Interesting article but disappointed in the overclocked benchmarks. AMD can say what they want about Excavator v2 cores but if these benches at 4.8ghz are legit its only going to slightly put it over the recent Athlon 860k. Im doing this comparison based on the future Athlon will be based off the A12 9800. My Athlon 860k gets a cinebench r15 score of 368 at 4.5ghz. IF it overclocked to 4.8ghz I'd bet it'd score right around the same 380 the A12 9800 did. On the plus side IF 4.8ghz is possible on the new Excavator v2 based chips and the power consumptuon is down thats a big plus. I was just hoping the new Athlons would be scoring a bit better say near 400 in cinebench r15 at stock clocks and for $100 or less. But hear this INTEL... I will never pay $180 for a dual core even if it does overclcock well. The new i3 7350k is a joke.

    AMD did something similar with the A8-7600 midrange APU. Announced it, launched it, allowed testing by tech sites, and gave OEMs full access, but it took a full 8 months before it was available to the general public.

    We already have Zen and Bristol Ridge is nowhere to be found anywhere apart from OEM systems. What a shame, would've made a decent office computer.

    Hi i bought a10-9700 with stock hs and a320m vh plus msi motherboard.. my cpu temperature is always at 50 to 60 degree is it normal?
