AMD Temash A6-1450 Performance (Acer Aspire V5) Update: Naked Pics

Posted on 11 May 2013 by



AMD-A6

I’ve been testing the Acer Aspire V5 122P, a subnotebook based on the new AMD Temash platform. As part of my testing I’ve been doing some CPU and GPU-specific tests that will give people and idea of the processing power and efficiency of the A6-1450 platform. You are invited to request a test if you feel it will add something to the assessment.

Test device: Acer Aspire V5 122P with 4GB RAM, 500GB Hard Drive. Original OS build (Windows 8)

Processes after boot: 59.

All tests run in High-Performance mode and CPU speed checked: 1.39Ghz.

Heat / Noise of the system will be addresses in the product review. No comment or summary is being made here. This post is just for test results. Problems of achieving a constant 1.39Ghz clock will be addressed in the Acer Aspire V5 122P review.

IMPORTANT NOTE: A background process is continuously taking 2-10% while these tests (System process, average 7%.) When assessing CPU performance the figures should be considered as 0.93 X total maximum possible.

CPU power usage.

Without specialised test equipment it is difficult to do this in a controlled way but by using Perfmon to show the battery power drain figures and running a pure CPU test in quiescent and test state and by noting the % CPU load used by the test process, a rough figure can be calculated. Some DC-DC losses must be factored into the equation but these are estimated at <10%. Update: There may be memory/bus usage during these tests.

Test done on high-performance profile under battery power.

Cinebench and Power Utilisation

Again, note that these scores are with an average 7% CPU being taken by a ‘System’ processing the background. Done under battery power, high performance mode. CPU is at 1.39Ghz during the tests.

Test 1 – Cinebench CPU multi-core – 1.3 (1.39 theoretical at 100% CPU availability)

Perfmon drain measured differential: average, high-power profile: Standing average: 6.4W (7% utilization, ave 1Ghz clock), test average: 13.8 (88.2% CPU load by Cinebench Process = < 7.4W)

Test 2 – Cinebench CPU single-core – 0.36

Perfmon drain measured differential: average, high-power profile: Standing average: 6.4W (7% utilization, ave 1Ghz clock), test average: 9.8W (37% CPU load by Cinebench process = < 3.4W)

Power figures assume all additional power drain is due to additional CPU load. Difference in core/Ghz power usage is high between the two tests but fan overhead and GPU rendering work must be taken into account. This could be a significant part of the power drain.

Cinebench OpenGL – 10.58 (best of three)

Power measurements using perfmon. Standing average: 6.6W (7% utilization, ave 1Ghz clock), test max: 17.7W Cinebench process was using 50% CPU. Differential: 11.1W

 

Platform Idle Power Utilisation

WiFi off, BT off, Sound Off, keyboard backlight off, Screen lowest setting, power saving mode, no foreground apps running, background tasks 7% average CPU utilisation. Power measured by Perfmon. (minimum figure taken.) Some pre-installed apps removed. (Office trial, WildTangent, Noton, Mcaffee)

Screen minimum: 4.14 W

Screen off: 4.04W

Screen 100%: 5.1W

Screen 50%: (enough for living-room usage) , 4.5W

Screen 50%, Wi-Fi On connected (802.11n, two walls from hotspot): 5.2W

Note/Warning: Keyboard backlight adds approx 1W

Power Director 10 Rendering Test.

Source: 55 second 1080p, 30Mbps, 25FPS, H.264 with DOlby audio.

Rendered in PowerDirector 10 with a 6mbps 720p H.264 profile in 79 seconds, Fast video rendering option not available.

Rendered in PowerDirector 11 with a 6mbps 720p H.264 profile in 54 seconds, Fast video rendering option available, enabled.

Rendered in PowerDirector 11 with a 6mbps 720p H.264 profile in 80 seconds, Fast video rendering option available, disabled.

Notes: Enabling ‘OPenCL acceleration’ in PowerDirector 11 as well as the default hardware acceleration resulted in no difference in rendering time.

PD11render-aspirev5122p

As with previous AMD APUs it seems that the CUDA acceleration isn’t that strong. Testing PD11 next. 

Performance is on-par with Intel Clovertrail. 720p editing possible with an SSD-based Temash system in our opinion. (PowerDirector 11 is a mid-range video editor that supports many forms of hardware acceleration)

Gaming – Just Cause 2 Demo

I’ve chosen this demo as it’s the one I use for Ultrabook testing and I’m glad I did because it’s just beat a Lenovo X1 Carbon X1 in optimised settings. In default settings it lies somewhere between the HD3000 and HD4000 performance results we’ve seen to date which is more than the 3D benchmarks would suggest.

If this was ifixit you’d probably being seeing a score of 8 or more because there are a lot of serviceable parts inside. Even the heatsink is easy take off. You’ll see a close-up of the AMD A6-1450 below. A world exclusive of course ;-) Click for larger images.

    nice work, thx a lot.
    “A background process is continuously taking 2-10% while these tests (System process, average 7%.)” found the same under win 7 on other pc’s. so far no idea how to stop this. this often is combined also with “strange” bursts of hard disk activity, draining the battery additionally.

  2. gmb says:

    You did CPU power usage, why no GPU power usage and CPU+GPU power usage? And you didn’t told what programm you used for CPU load. If you used Cinebench 11.5 then you better use Prime95 or something similar to measure the max power usage. Cinebench 11.5 was never that heavy.

  3. Chippy says:

    gmb, good point. I re-did the tests with Prime95 torture tests and saw some higher figures. Article is updated.
    REgarding GPU test, i’ve done one combined now but it’s hard to find a pure GPU test.

  4. gmb says:

    Isn’t Furmark a GPU pure test? If not, the total max power usage would be interesting. Prime95+Furmark or something like that would push it to hell. Btw, in some tests it’s not clear to me if you tested with Turbo enabled.

  5. Anton says:

    Chippy, thank you for these tests. And wath about hardware accelerated playing 4K video? It is possible on this APU? http://u.to/6F1yAw

  6. Tom says:

    How’s Linux support on these AMD APUs?

  7. Tom says:

    “A background process is continuously taking 2-10% while these tests (System process, average 7%.)”

    You should probably find the cause of that to make your tests more meaningful. I have a Clover Trail tablet which idles 1%-3%. 2%-10% on a more powerful chip is a lot. It could be driver problems which users should be aware of when deciding to go with AMD based devices.

  8. Chippy says:

    Anton. 4K testing is on my list although I don’t have a 4K monitor!

    Tom. I’m going to do a fresh re-build on an SSD to try and solve this. There’s an issue here.

  9. gmb says:

    Notebookcheck was unable running CB 11.5 with 1,4 Ghz on all cores. What did you do to get 1,4 Ghz on all cores?

    Chippy Reply:

    It’s difficult to say but on boot this morning I couldn’t get more then 900Mhz. After one standby cycle, nothing else, I was seeing 1.1ghz and after another standby cycle I was seeing 1.1ghz [correction 1.4Ghz] which stayed through all tests. There’s some sort of bug here in my opinion.

  10. gmb says:

    This is strange.

  11. Fruit says:

    A test of a 10-bit H.264 video (a.k.a. HI10P profile) would be nice. 1280×720 or 1920×1080 resolution, it would be interesting what can the small CPU achieve in that.

    /A suitable decoder would be LAV Video with MPC-HC player; or it could be tested with VLC or MPlayer2./

    (This profile has no hardware acceleration support and needs to be decoded fully in software + teh CPU load is higher than high profile.)

    Thanks for the testing, this notebook is quite interesting.

  12. digi_owl says:

    AMD driver issues, security software doing “screensaver” scan?

    And from personal experience, you can tweak the min and max allowed CPU frequency in the Catalyst Control Center (seriously) independently of whatever the detailed settings are for the Windows power profile.

  13. Tralalak says:

    Hi Chippy,
    3DMark06 result is resolution of 1366×768 pixels ?

  14. Chippy says:

    Sorry Tralalak. This is 1280×7680 resolution in the test. (3DMark06 basic edition) I’ll add info above.

  15. Chippy says:

    Naked pics added!

  16. Zamir says:

    You can google Intel Atom and i3 bugs and find millions of users who had to deal with a number of problems from wi-fi unreliability to horrible glitchy graphics.

    By comparison, AMD already has their GPUs which support ZeroCore power and it won’t be long before their Jaguar APUs have updated power firmware and drivers.

  17. Vampirr says:

    Chippy…

    Can you please turn off two cores and clock other cores to 2-2.8Ghz to see real performance of A6-1450 if all cores were used, thank you.

  18. Manuel says:

    Hello Chippy,
    have you find solutions for the problems with the background process or the turbo on all four cores yet?
    Thank you!

    Chippy Reply:

    Turbo works on all four cores after repeat sleep-resume cycles. Sounds like a hug to me. As for background process I fear a poor OS build. Suspect some sort of logging or debugging is enabled.

  19. Manuel says:

    Hello Chippy,
    thank you. I tested it on my V5 122p and the turbo works on all cores, too. And I found out that the background process is about 2-6% when turbo works on all cores. Without turbo on all cores its about 6-12%. With new beta driver 13.6 from AMD I reached 1.36 on Cinebench cpu test istead of 1.31.

  20. Chippy says:

    Great news Manuel!

  21. Michael says:

    Hi Chippy and/or others that have access to such a device,

    did anyone of you test:

    – whether the memory is upgradeable with a 8GB SO-DIMM?
    The soldered 2GB + 8GB should add up to 10 GB max. memory. Did anyone try that?

    – whether you can plug a displayport MST hub into this Acer special port
    and if yes how many FullHD monitors you can actually drive with it?
    (http://www.club-3d.com/index.php/products/reader.en/product/mst-hub-1-3.html)

    Thank you!
