Hello all,

I just wanted to share the results of my fairly small A8-6410 APU performance analysis. For those who don't know this is a Puma+ based quad core APU. This is the successor to Jaguar which are the 8 core cpu's in the xbone and ps4 as well as the kabini desktop quad core variant (and some other laptop apu's).. This APU is running at a boost of 2.4ghz and a base of 2.0ghz. The gpu core runs at 800mhz. I am testing between 1600mhz CAS11 and 1866mhz CAS10. The results were a bit better than expected on some, and fell flat on others. I will be updating this as I get more results but as there is very little out there on how these APU's actually perform I'd figure I'd do everyone a favor and show these are fairly decent, very affordable 15w tdp APU's.

The main testing I did can be seen in the below chart, it is for the in game benchmark of the source engine.



Edit: graph is blurry for whatever reason.. see below:

AVG FPS
DDR3L 1600 CAS11
LOW SETTINGS - 640x480 NO AA 144.5
MAX SETTINGS - 1368x768 NO AA 75
MAX SETTINGS - 1368x768 2X MSAA 57.33
MAX SETTINGS - 1368x768 4X MSAA 55.33
MAX SETTINGS - 1368x768 8X MSAA 53.33

DDR3L 1866 CAS10
LOW SETTINGS - 640x480 NO AA 149.75
MAX SETTINGS - 1368x768 NO AA 85
MAX SETTINGS - 1368x768 2X MSAA 66
MAX SETTINGS - 1368x768 4X MSAA 64.33
MAX SETTINGS - 1368x768 8X MSAA 62

As you can see, the bandwidth does play a role almost netting at 10fps gains at best and 9fps on average when the stress is more on the GPU portion. This was more than I expected, but being that this architecture is unfortunately limited to single channel the extra memory bandwidth really helped here.

On a side note, it is amazing to me that the scaling going from from 2x > 4x > 8x MSAA was a 2fps drop each time. I reran all of the tests multiple times to confirm this but it averaged that each time. No AA is clearly still best with these APU's, though.

Unfortunately, when I was doing the more cpu bound portion I was disappointed in the minor 5fps gain here. Again I reran this multiple times to be sure but it averaged around 5-6fps gained each time. I was thinking this cpu to be more bandwidth bound than it is, but with such high frame rates already it made almost no proper gains in that kind of scenario. At least for the source engine.

Though it's not in a graph form yet, please also see the below

SKYDIVER 1.0
DDR3L 1600MHZ CAS11 6GB (4GB & 2GB)

Score Graphics Physics Combined

1754 1786 1578 1844

To...

DDR3L 1866MHZ 8GB CAS9 (8GB)

Score Graphics Physics Combined

2035 2036 1977 2123

This was at the default Skydiver 1.0 settings set to 1366x768

I also did a Firestrike Physics test at the lowest possible settings and 640x480 and the scores were near identical so no gains there. Scores were both around 2950

Anyways, I will be adding more tests to this but I wanted to share it with you all, especially those considering an AMD laptop. I paid under $300 for mine new at bestbuy so I consider it a great value. The battery life is great as well. Lenovo G50-45 (see specs in sig).

Please let me know if you can think of other benchmarks that would be more useful! Thanks!

Nice

I wish there was a program like brazos tweaker or k10stat for beema. AMD overdrive doesn't even recognize it.

It might be helpful to have AIDA 64 ram benchmark scores for the settings being compared, just a thought.

Good job with the comparison.

Thanks, I'll look into setting that up. Any other useful benches? I'm mostly shocked by the minor physics score changes in firestrike. I assumed on the absolute lowest settings at 640 they would show variance but they were pretty much dead on each time.

1600MHz RAM bench.



I challenge you to beat that latency.

Here is a review of my G40-45.
http://www.overclock.net/products/lenovo-g40-45-aei/reviews/6985

I think the laptop was the best I could find in its price range. While there are Intel ones at this price they are dual cores and perform the same. What I find interesting is that most laptops here have dedicated GPU's but not in the US.

The a8-6410 afaik is beema apu base on this review http://www.notebookcheck.net/AMD-A-Series-A8-6410-Notebook-Processor.122644.0.html or the beema and puma+ is the same....?

On my 3rd sig rig i have the same APU laptop but its not lenovo its HP and the discrete GPU is R7 M260..http://h20564.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c04439417

I planned also to upgrade the HGST 1TB 5400rpm HDD to 256GB SAMSUNG OR INTEL SSD and the RAM also to 2x4GB 1866 ...

The theory of dual graphics of this APU laptop is that its having a iGPU for some light graphic demanding task and automatic switching to discrete GPU if needs a more demanding graphics application or games.... then it came to my mind if its worthy to upgrade to 2x4 GB 1866 ram from 1x2 and 1x4GB 1600 ,cause on this scenario the iGPU only will gain the performance improvement but i have no idea if also the discrete will be included on the performance gain.... please correct me if im wrong

They are the same, mullins/beema is the code name, but Puma+ is the architecture. Much like Vishera is Piledriver on the AMD FX side.

I stuck with a single 8gb stick vs using two sticks to save on power (obviously this is miniscule but anything helps on a laptop). Also, saves on weight (again obviously ridiculously minimal) - but more importantly to have another ram spot open if I so needed to add more for whatever reason.

Please keep in mind, this APU only supports single channel so going for two sticks makes zero difference. Also, make sure to get CAS10 1866 as it will also help slightly and is generally the same price.

The IMC is single channel, adding a second stick will do nothing for performance.

My laptop does switch to the dedicated GPU when I run a game but that still doesn't make it a viable gaming system. GTA V runs terribly due to the weak CPU cores but older games run pretty nicely even on the iGPU. Sadly this means that even Mass Effect 2 doesn't run fluidly but has problems but this is what you get when you pay this price and switching to Intel and a GTX 720 yields the exact same performance but with fewer CPU cores.

Carrizo FX is now available with FHD IPS Dislay on the HP Envy 15 in the US. Finally some proper displays on AMD notebooks.

First of all sorry for my bad English (Indonesian)...
I've got a G40-45 (A8-6410 2.4GHz / 2GB R5 M230 / 4GB 1600Mhz C11 Ram)
What you think about 2x4 GB 1866MHz C10 Ram?
Will it work?
Can you help me dude?

It should work, but it will not run at 1866Mhz. At 15w, the A8-6410 is restricted to 1600Mhz RAM.
I bought an 1866Mhz CAS 10 stick before I knew about the TDP restrictions. Although it only runs at 1600Mhz, I actually gained 2 latency ranks with the upgrade. I went from 1600Mhz CAS 11, to 1600Mhz 9-9-10-28.

Also know that the A8 is single channel memory only so you'd be better off getting 1 8GB stick.
like one of these:

In your opinion, whic one is the best, 1866 c10 or 1600 c9 ram? Or the same?

They are essentially the same, since the CPU wont run above 1600 and you should get a good latency improvement either way. But from what I've searched the 1600 c9 is cheaper.

Should not be the case at all.. in fact the whole point of this thread was testing 1866mhz on it. The A8 6410 handles 1866mhz as the max default ram speed.

ya, I got mixed info when I was trying to figure out why my toshiba wouldn't run the 1866 stick at the rated frequency. Although 1600 CAS 9 should be about equal to 1866 CAS 10.

For cpu + discrete gpu, yea they are similar. However being that the gpu portion of apu is already starved for bandwidth 1866 will definitely perform better especially if you play AA or stick to higher res. I went from cas11 1600mhz to cas10 1866 as seen in the first post and I believe many of these laptops ship with crappy memory specs as well unfortunately.
