Today we are looking at the low cost, low power AMD APU – called the A4 3400. In terms of the hierarchy of the Llano APUs this particular chip is closer to the bottom of the pile. That said, while it isn't aimed at an audience who enjoy playing the latest Direct X 11 games at the highest resolution, it caters to a much broader audience and aims to be a jack-of-all-trades in the APU market. At less than £50 inc vat, is this an ideal foundation for a low cost system?
The A4 3400 is a dual core processor clocked at a respectable 2.7Ghz with 160 Radeon cores running at 600mhz. This could form the foundation for a new system … capable of light gaming, while still having enough horse power to handle a variety of tasks.
The A4 3400 and the Gigabyte motherboard under review also support Hybrid Crossfire, with certain AMD graphics cards. To test this potential load-sharing and possible performance increase between the APU and a dedicated GPU, we installed a low-power version of the VTX Radeon 6450, the highest model of graphics card that is supported by this board that allows for Hybrid Crossfire capability.
The Radeon 6450 model we added to test the Crossfire capability has 1Gb of onboard memory.
Today we will see how the AMD A4 handles a myriad of duties, including light gaming and encoding tasks.

£50 for the cpu and £50 for the gigabyte mobo is pretty good isnt it ? id always been put off bying a system like this for my tv as the motherboards were often well over £100 even if the processors were cheap.
im tempted now. shall try and talk my credit card into accepting the charge.
Nice setup on Dabs for these, makes it easier to work out where to get the bits,
only thing is, they should have made some complete systems with memory, power supply etc, took a few quid from them. would have worked a lot better. seems a bit ‘half assed’ having a page with the A4’s and motherboards and nothing else. these are ideal for students who maybe need the help
Hybrid crossfire has always sucked, glad to see it hasnt gotten better all of a sudden.
not a bad deal for the price, but its probably slow as molasses for a work machine. Adding a cheap SSD might help.
Im curious, can it be overclocked?
its pretty good value for money. Not sure id want one, but would be good for a server system
I have that proc. and Gigabyte MB and i am very satisfied with that. Plus i got Ati Saphyre graphic card with 1 GB. As it was said, it is really good for lite gaming, and very cheap. And @Brian, yes it can be overclocked! 🙂
Is there such a thing as an intel atom quad core? The 6450 is pretty puny so really adds not very much except heat and cost. A 6670 or better would kick things up a notch/
