Comparing the full specifications of the HD 5870 to its predecessor shows that it sports some very impressive upgrades over the RV770 chip. Using a 40nm process, ATI have managed to fit an impressive 2.15 billion transistors on a 334mm2 die size. This is over double that of the HD 4870 which consisted of a "mere" 956 million transistors. So what is ATI using all those extra transistors for?

The first thing we can take notice of in the specifications table is that the number of stream processors, texture units and raster operations have all doubled! While this does not match Nvidia's GTX 295, it is a first approximation of what we can expect from the new card. The core clock has been boosted by 100 MHz and the memory, by an impressive 300 MHz. This is effectively a 1.2GHz increase considering the use of GDDR5 memory. Impressively, those changes help achieve a compute performance of 2.72 GFLOPS, over double that of the HD 4870 and just under 1 GFLOP higher than the current crown holder, the GTX 295.
