Help choosing an APU

post #1 of 5
Thread Starter 
Hi i'm new here, sorry if I posted this in the wrong section but I couldn't find an apu support section or anything. I'm wondering if I should get an AMD a10-5700 or the 5800, the help i'm wanting is if my PSU will support it. The desktop I use is here: http://bit.ly/GBx9Nx if I get the 5700 I know for sure it will work because it's 65w (same as the a6-5400k it came with) but the 5800 is 100w and only a couple dollars or even one dollar more than the 5700. I added 4 gb's of ram to it also if that affects anything really, so will my PSU (stock 300w) be able to support the 5800 fine with no problems or should I just get the 5700? I know there's not much of a difference between the two except the 5800 is unlocked and only like one dollar more lol, thanks for the time. thumb.gif

At full load (CPU+GPU) the A10 will only use about 50 more watts than the A6. Total system power is probably around 200W, so the 300W PSU in your computer should be fine.

The motherboard is also compatible with the A10, so no worries there. Motherboard Specs

The A10 will be quite an upgrade especially in the graphics department. The 7660 is much faster than the 7540.

To get the best performance out of the A10 you may want to go with 8GB of RAM (2x4GB), so that the RAM will run in dual channel. APU's see significant performance increases with faster memory. Check out this thread for more info.

Thanks a lot for the help, also I added 4 more gb's of ram (same speed 1600) so I have 10 gb's now, is that not the same? I can get 2x4 if that would be better, as iv read all over you don't really need more than 8 gb's of ram.

Two 4GB sticks would give you the absolute best performance, but three 2GB sticks and one 4GB stick would probably not be noticeably slower. Asymmetric dual-channel is just not quite as fast as true dual-channel. There is probably not much difference until you start using more than 8GB of RAM, because the last 2 GBs of RAM would be addressed in single channel.

I have never tested a set-up like that, so I am not positive of what the actual performance difference would be.

If you already have the RAM I would just go ahead and use it, since the performance difference is probably not that large.

Alright, thanks again iv been wondering this for a couple days.
