AMD Llano A8-3850 w/ Radeon 6670. Anyone tried it?

Hello All, :hello: 

I've been wondering what the performance benchmarks would be for an AMD Llano A8-3850 APU crossfired with a Radeon 6670 GPU? This configuration would make the system into a 6690D2; the highest configuration that the Llanos can be without the need for a stand-alone dedicated graphics card.

I've been curious into making this type of build. I've configured my system in Newegg and the cost would be somewhere around $500 ~ $600 depending on the components chosen. But before taking the plunge, I wanted to know what the gaming benchmarks would be for a system like this.

Other websites I've visited usually only list the benchmarks with the stand-alone APU, or with the 6570 or 6450.

Has anyone built a system with the A8-3850 and a Radeon 6670?

Thanks!

I remember reading an article somewhere on this site about the A8 benchmarks using crossfire etc and i believe it suggested buying a more powerful dedicated card instead would be a lot better for gaming. I'm actually considering building and APU rig atm but haven't done it before so no first hand knowledge, I believe for gaming purposes you would want a more powerful graphics setup though.

The best card you can crossfire with current APU is the 5670/6670. The Phenom [2?]-based APU is coming out so I'll wait to see how they work out. Here's what to expect crossfiring with the a8-3850: http://www.anandtech.com/show/4476/amd-a83850-review/6


I've read that Anandtech article. Unfortunately, they seem to be benchmarking the 6630D2, which is the APU crossfired with the 6570. The 6690D2 is what I'm looking for. Although, with those benchmarks on the 6630D2, it looks quite promising. :wahoo:

id be interested to see how prelevant microstuttering would be in that kind of setup.

Best solution

I have that exact setup of the 3850 apu and 6670 discrete graphics at home. Check youtube you'll definitely see the gaming performance/benchmarking when you type both in the search. At home, I don't have any direct x 11 games except for Dirt 3 which came with the video card and when I don't run crossfire, average fps is about 43 with minimum fps at 35. WITH crossfire gets me to about 60+ fps avg and 50+ minimum fps no hiccups whatsoever

Oh wow. I didn't think about searching Youtube for that info. Thanks buddy. ;) 

This type of config looks very impressive. The only caveat that I see to this config is the somewhat high price of the hardware if you're building a system like this completely from scratch. My current config in Newegg looks like this.

CPU: AMD A8-3850 2.9GHz

Mobo: Biostar TA75M+ FM1 AMD A75 Micro ATX Motherboard

RAM: 16GB G.Skill Ripjaw X DDR3-1600

GPU: XFX HD-667X-ZAF3 AMD Radeon 6670 1GB GDDR5

PSU: Antec Earthwatts Green EA-380D 380 watt power supply

Case: APEX TX-381-C Micro ATX Tower Case

HDD: Samsung Spinpoint F3 HD103SJ 1TB 7200RPM Hard Drive

DVD: ASUS 24X DRW-24B1ST/BLK/B/AS DVD Burner

Accessories:
Rosewill RCR-IM5001 USB2.0 75 in 1 internal Card Reader w/ 3 ports USB2.0 Hub
Biostar CABLEUSB3.0 USB 3.0 Cable Bracket

Everything total from Newegg would cost $622.90. Not including shipping.

Another $59 would need to be added if the DVD drive was replace with this Blu-ray burner.
LG Black Super Multi WH12LS30

Adding an SSD to the mix would up the price by about another $120 ~ $150.

I wonder what the cost would be to build an i3 or i5 system with a dedicated GPU like a Radeon 6770 or 6850? Obviously mobo, CPU, GPU, and PSU would need to be changed, but every other component would stay the same

I might just do this rig out of morbid curiousity. :pt1cable:

the intel varient will cost you 200-250 more depending on mobo chosen.

your build is very cheap seeing as how you are purchasing a case, and drives.
i am curious as to how the builds will stack up once more of them are out there.

doesnt the A8 3850 cost more than the phenom 955? i know it does in australia. I would prefer the faster 955 and spend the extra money on a better vid card and not have to worry about crossfire.

I built one up and found my money was better used on traditional build however if you need lower power set up its way to go. I have a75 board and a8 chip for sale if interested
