The Radeon HD 3800 family retains the audio-routing ability first seen on the previous generation's best. Again, head back to our in-depth look if you're befuddled by what's going on here. The ROPs are, as far as we can ascertain, identical, too, outputting a total of 16ppc, and feature the same MSAA resolve for some funky custom-filter anti-aliasing (CFAA), right up to 24x.

The Radeon 3870's 16 FP32 texture-filter units can filter at high-precision (FP32) at half speed - that's eight pixels per clock cycle (8ppc) - or run FP16 at full speed, so 16ppc. The tesselator engine is carried over, naturally.Ĭontinuing the theme of harvesting from R600, Radeon HD 3870 - code-named RV670 - is equipped with an identical 16 texturing units and 16 ROPs, and all operate at the same speed as the shaders no split-clocking here. The Radeon 3870 packs in a unified shader core - meaning that its scalar-based stream-processing units can be allocated to work on either vertex, pixel or geometry data - with the same '320' units, arranged in four blocks (SIMDs) containing 16 processors.Īs each processor contains five superscalar arithmetic logic units (ALUs), AMD sums it all up - (4x16) x5 - to arrive at the wonderfully-large 320 quotient.

Please feel free to head back here to our in-depth look at the architectural underpinnings of the 2900 XT, to save excessive reproduction of known facts. The Radeon HD 3870 GPU is based on the Radeon HD 2900 XT, albeit with a few extra bells and whistles that we'll explain in a moment. Thinking of the past gives us a glimpse in to the present.
