In many respects the Radeon HD 4350 is the smaller brother of the HD 4550 that I reviewed less than a month ago. The HD 4350 has 80 Stream Processors, 8 Texture units and 4 ROPS which is the same number as found on the HD 4550 cards. It is built upon TSMC’s 55 nanometer press with 242 million transistors ATI built the HD 4XXX series stressing performance per watt and the HD 4350 design is.
The HD4350 has a 64-bit memory bus. The memory bus on the video card combined with the memory clock speed determines how much memory bandwidth a card has. The HD 4350 has a memory clock speed of 1 GHz effective, meaning that the card has 8GB of memory bandwidth available to it. The card uses DDR2 memory which is very inexpensive memory right now but the card is inexpensive so it’s a good fit.
ATI’s big push on video cards is on DirectX 10.1 features. The DirectX 10.1 feature set is going to be more featured in the near future with big game companies like EA and Sega announcing support for it and DirectX 11 video cards needing to support DirectX 10.1 to be compliant. NVIDIA argues, with some justification that DirectX 10.1 is a minor feature update to DirectX 10.0. In any event cards like the HD 4350 do not have the performance to take full advantage of DirectX 10.1 and it shouldn’t be a major factor either way.
ATI’s Universal Video Decoder is their decode software for HD content like Blu-Ray disks and H.264 video playback software. The HD 4350 is capable of full speed Blu-Ray playback but ATI states that it might not have the horsepower to do picture in a picture dual stream playback that the other HD 4xxx series can do. The HD 4350 reference card is designed to offer HDMI Audio (7.1) through the included HDMI port making it ideal for the Home Theater PC enthusiast.
