In this review, the 5850 was clocked to the same speed as a 5870 (850/4800) and when the smoke cleared, it was a whopping 2% slower than its older brother (they also test a 1010/4960 OC, but that's besides the point). The 850/4800 clocks were achieved using stock voltage no less.
The 5870 has 160 more SP's (+10%), 8 more TMUs (+10%) and is clocked at 850Mhz Core (+10%) & 1200Mhz Mem (+17%) than the 5850, yet only manages to be +2% faster with the same clock speeds. This indicates that those extra SPs and TMUs are more dead weight than actually adding to the performance of the 5870 card.
I would really like to see this review's methodology replicated in another review and tested for repeatability, but for the sake of making inflammatory statements, I will jump to conclusions and say that 5870 is the 2900xtx revisited.
This only further fuels my desire for a 1280 SP 5830. How far from the 5870 would it lie with identical clocks?
5850 is by and far the card to get.
Discuss.
