Radeon HD5570 Video Card Specifications

The HD5570 has hardware specs that match up pretty closely to the HD5670 that was released last month. The clock rates are a little lower, and the GDDR5 has been replaced by GDDR3, but the GPU is basically the same. You can see the HD5570 specs in detail a little further below, and the parts that don't quite equal the HD5670 are reflected in the power numbers. ATI has done everything they possibly could to get these numbers down to where they are, and still keep its performance close to the HD5670. In a typical HTPC box, everything is jammed in tighter than sardines in a can, and the low profile of the sleek, shiny chassis only allows for small fans on the back. So, power is King. If the device consumes power, it had better do something useful with it, and not just dissipate it away, as waste heat! While the specs give us a good clue to the performance of the HD5570, ultimately, it's the real-world performance we care about, the design tradeoffs that were required to achieve it, and the price for that performance. This graphic puts the general pricing v. performance strategy in perspective:

But before we get to our detailed teardown and testing, let's look at the actual HD5570 specs:

Radeon HD5570 Specifications

  • Process: 40nm
  • Transistors: 627 million
  • Engine clock speed: 650 MHz
  • Processing power (single precision): 520 GigaFLOPS
  • Texture Units: 20
  • Texel fill rate (bilinear filtered): 13 Gigatexels/sec
  • ROPs: 8
  • Pixel fill rate: 5.2 Gigapixels/sec
  • Anti-aliased pixel fill rate: 20.8 Gigasamples/sec
  • Memory Type: GDDR3
  • Memory clock speed: 900 MHz
  • Memory data rate: 1.8 Gbps
  • Memory bandwidth: 28.8 GB/sec
  • Maximum board power: 42.7 Watts
  • Idle board power: 9.7 Watts

OK, tired of looking at numbers, let's take a closer look at the hardware, then? ATI was kind enough to send us a sample of the 1GB reference design video card with a full copper active cooling setup, so let's examine the ins and outs of the newest low-profile ATI video card.
