Upgrading Graphics - AMD Kabini (A6-5200)

Fri Dec 27, 2013 5:37 pm

I have a little AMD Kabini mini-ITX system, and it runs games surprisingly well.

I have roughly $100 to upgrade the system, and I was interested in getting a low-end AMD card for crossfire, but I cannot find anywhere on the Internet any mention of 1) what cards it will crossfire with, and 2) what version of GCN it runs internally.

All I can find in my extensive Internet searches is that crossfire is supported by this APU in some way. Does anyone know which video card I should be pairing this APU with?

I think a 6770 and below is the max. Correct me if I'm wrong.

I can't imagine that dual graphics (crossfire officially means two or more discrete GPUs, apparently) with 2 very low end GPUs would be worth it. The 7770 starts at around $100 and should have better performance without the issues of crossfire/dual graphics.

To actually try and answer your question, it looks like Kabini dual graphics only supports some 8000m series mobile parts. This is the best link I could find: http://hardforum.com/showthread.php?t=1737549

This link has some info about what iGPU the various Kabini versions use: http://www.anandtech.com/show/6976/amds ... i-temash/4


Edit: If your power supply doesn't have a 6-pin PCIe connector the best you can do is a 7750 with GDDR5. It should still be several times as fast as your current GPU.

Yeah, forget about a crossfire setup for the two reasons that the IGP in Kabini can only "crossfire" with an extremely limited set of OEM-only GPU SKUs and that the IGP would likely hold back a more powerful card in real-world scenarios.

If you are set on getting an AMD GPU, then get a 7770 or 7750 (with GDDR5) that should be out there for < $100. If you can splurge and go over $100 but stay under $150, you might like the R7-260X or the Geforce 650TI, which got a favorable TR review for its price bracket.

The reason that the APU only supports hybrid crossfire with low-end cards is that a single mid-range card provides much better performance.

What is the resolution of your monitor?
What sorts of games do you want to play?

Radeon HD7750 uses AMD's Cape Verde GPU for $100 or less. It is available as a low-profile card that will fit into slim-line cases. It is also the best-performing graphics card that is powered only from the PCIe slot and does not require a 6-pin power cable.

Radeon R7-260X / HD7790 uses AMD's Bonaire GPU for $120-$145. It's going to be a full-height card that requires a 6-pin PCIe power cable.

GeForce GTX650Ti provides a little less gaming performance for the same price.

Radeon R9-270 / HD7870, based on AMD's Pitcairn GPU for $180, provides sufficient performance to run most currently-available games at decent frame rates at 1920x1080 resolution.

I agree with others that trying to crossfire a Kabini wouldn't be worth it. I also worry about that little guy making things CPU limited. (Maybe Mantle can help that....we'll see)

I think your budget is in the right range though. I surely wouldn't spend more than $100 if it's being paired with that CPU. You can get a 7790 or 650 Ti for $100 after MIR if you catch them on sale. Keep this performance graph in mind when buying (and that the 7770 is about 25% faster than the 7750 GDDR5). IMO, 7750's are attractive only because they don't require external power. If you look at pure performance/price, going from an $80 7750 to a $100 7790 gets you well over 2x performance.

Disclaimer: I bought a 7750 (DDR3) on newegg open box for $31 after MIR that I gave to a friend for Christmas. It plays Bulletstorm, Grid2, Tomb Raider, etc at 1080p, low-medium settings, 35-40fps (Portal 2 medium-high settings, buttery smooth), hooked up to a Core 2 Duo E6300. The price was right, but it was difficult to get things looking ok at 1080p and retain playable framerates. Lots of tinkering required. I think that E6300 was introducing some CPU limitations.

I'll pile on top in saying don't use crossfire. It's always better to use a more powerful single-GPU whenever possible. Not only for performance, but less driver issues and usually lower power usage.

Also, just throwin it out there, I've got a GTX460 1GB (eVGA, Superclocked) that I've been meaning to sell. Looking at recent Ebay sold listings, I'd probably put $75 on it. What resolution do you run?

I think they'd get a decent boost from Mantle if the multi GPU features they've announced will be out there up front.

Don't know what they play that'll use it, but still worth mentioning.

The 7750 is a great little 720p card.
There's nothing too bad about playing at 720p, especially since you'll see 50+ fps at decent detail levels in most games at the moment.

For 1080p you probably want a 7770 at least. The 7770 was never a bad 1080p option for the money but the 7790, 650Ti (or R7 260 if you can find a deal) is a welcome boost in some of the more demanding games like BF4, Crysis 3 etc - that extra bit of performance takes some of the rare sub-30fps low points and makes them at least 35fps which is a welcome improvement to playability.

My HTPC had a 7750 in it at one point and it was great for casual gaming but as I spent more time on the sofa I wanted more to play the more potent games.

TechReports review claims its a newer version of GCN, so I'd expect 1.1 like the newer cards.

I would not crossfire your integrated graphics with anything. The dedicated card usually runs faster on its own.

If you do have some extra molex or a PCIE power connector I would go with the previously mentioned hd7790, it is a much better card then the hd7770. Also it uses around the same amount of wattage. with the 7790 uses a max of 85 watts and the 7770 uses a max of 80 watts worst case scenarios. Here is a great comparison of the 2 cards.

If you have a super weak PSU a hd7750 will serve you well, it uses around 45-55 watts.

Given that you're running a mini-ITX box, I'll second the recommendation for a low-profile Radeon 7750. It's fantastic at 720p and still does a fine job at 1680x1050, too, though clawing up to 1080p will usually require a little bit of detail reduction. For an A6 Kabini chip you should be well-served by it.
