Radeon Video Card Specifications

I mentioned in the introduction that the HD5670 had hardware specs somewhere below an HD5750. You can see the 5670 specs in detail a little further below, and they're a mixed bag compared to the 57xxx series. The memory is on a slightly slower clock, but the GPU is running faster than a stock HD5750. While the specs give us a good clue to the performance of the HD5670, ultimately, it's the real-world performance we care about, and the price for that performance. This graphic puts the general pricing strategy in perspective for you:

But before we get to our detailed teardown and testing, let's look at the actual HD5670 specs:

Radeon HD5670 Specifications

OK, tired of looking at numbers, let's take a closer look at the hardware, then? ATI was kind enough to send us a copy of the 512MB reference design video card, so let's examine the ins and outs.
