With the RV620, AMD/ATI has finished it's 55nm product line-up. Following the footsteps of the RV670 (aka 3800 series), which came out first, and shortly after the RV635 (3600 series), the 3400's target buyers that are less interested in 3D gaming, and more in price and the options to build an HTPC.

This graphics card has some characteristics that, because of it's limitations when it comes to games, seem rather useless:  DirectX 10.1/ Shader Model 4.1 support, PCI Express 2.0 or CrossFire technology. Others like DisplayPort and PowerPlay (for more efficient energy managment), will, on the other hand, end up being quite interesting.

This chip is very similar to the RV610, and shares many goals with the HD 2400, so let's see how it compares to the "Pro" version. As far as CPU utilization is concerned (during video playback), the new Radeon isn't much of an improvement. Where it does help, is in games, achieving 26.73% more frames per second. You can reduce the difference to 6.31% by increasing core and memory speed on the 2400 Pro, but you could also overclock the 3450 if you wanted, right?.
