AMD A10 and A8 Trinity APU: Virgo CPU Performance

12 thumbs up

We took a bit of time to overclock AMD's higher-end A10-5800K APU as it'll likely be one of the more popular chips in AMD's new line-up that performance enthusiasts will want to tinker with.  Overclocking the A10 is somewhat delicate work, perhaps more so than previous AMD architectures. 

Dialing up frequency on the IGP will undoubtedly contribute to additional thermal stress on your cooling solution, affecting the CPU, and vice-versa for that matter. You also do not need a lot of extra voltage in order to overclock AMD's new desktop APU.  Crank VID too high and you'll generate excess heat that will cause the CPU to throttle without high-end cooling.

Overclocking AMD's Latest A-Series APU
Pushing the CPU and GPU to the limit
Our tool of choice for stress testing was Maxon's Cinebench R11.5.  Cinebench allows us to test full, 100% CPU and GPU loads depending on which module of the test is run.  Perform multiple reps with Cinebench and you can pretty much squeeze out an unknown marginality in an overclocking effort.

 

We settled in on a 1.418V VID core voltage on the CPU with a stock 100MHz reference clock and a multiplier of 44X, giving us a top CPU speed of 4.4GHz under load.  This was achieved on standard air cooling and our DDR3 system memory set to 1866MHz. Our GPU speed was able to hit 1GHz with full stability as well, over a stock speed of 800MHz. 

This may seem like a modest overclock but we accomplished this with a run of the mill aftermarket air cooler, the Thermaltake TR2 R1.  Results may vary chip-to-chip and system-to-system but with more robust air cooling, liquid cooling or some other higher-end solution, there is definitely even more headroom available beyond what we're able to show you here.

 

 

The benefits of overclocking are apparent as always, with roughly a 10% kicker in CPU performance realized and a 15 - 17% increase in GPU performance for the overclocked Trinity A10 APU. 

On a side note, overclocking the GPU on the A10 is easy money. With a simple push of the clock slider 1GHz is attainable with virtually no fuss.  Overclocking the CPU can take a bit more finesse with reference clock speeds, multipliers and voltages to balance.

I never thought I would say this but I am going to and I hate it. I am re-building a PC for a lady who is an private Architect and I will be replacing her PHENOM II X4 965, MB, PSU, and Nvidia GPU with a ASRock X79 Extreme3 LGA 2011 Intel X79 MB a ntel Core i7-3820 Sandy Bridge-E 3.6GHz a SeaSonic X750 Gold 750W ATX12V V2.3/EPS and a XFX Double D FX-787A-CDFC Radeon HD 7870 GHz Edition and 8 more GB's of DDR3 added to the 8 she already has. I have no doubt she will be amazed by the system that comes out of it compared.

It sucks though AMD needs to get back on there A game. If it was a gaming computer I might consider a Bulldozer when there released but right now for a top end PC or at least up until now (looking forward to seeing what Bulldozer actually does) or relatively soon for a top end PC there not in consideration etc for a general user no matter whether there an architect or not. General user ok and do not forget I have a Phenom II x4 065 system I built personally sitting right next to me, but the one I am on is an Intel core i7 one.

And how your post sticks with a review of entry level APU?

I would stick with nvidia for Autodesk products.

NVIDIA makes better cards for professional use. AMD doesn't cut it. There are driver issues with Cad-Cam programs.

And why would you (rapid1) buy a gamers video card for someone who is using Autodesk?

So if Trinity is close to an i3, then a Piledriver 4 module should approach i5 territory?

How sad, this article only got 4 posts. Must not be much love for AMD out there anymoreCrying

I've personally have been wanting to try out the new apu's. They sound as though they have great performance for budget systems. I can't wait to see what they're about.
