Sapphire 5970 Toxic Review


A little while ago we took at look at the Asus Ares and discovered that whilst it was absolutely a thing of immense power and desirability, it was also fiercely expensive. So what do you do if you want a product that has phenomenal power, a certain exclusivity but wont require you to sell a kidney to obtain one?

Sapphire have always been one of the premiere ATI partners and have been producing premium versions of each generation of ATI GPUs. Anyone who has been around the hardware scene for a while will know how highly the Toxic variants are thought of, and so when we discovered that Sapphire were going to bring out a Toxic version of the already excellent 5970, we couldn't wait to get our hands on one.

The HD5970, for those of you who need a little memory jog, is ATIs twin GPU behemoth and at the time of release was the fastest single card available. It did however have one small drawback. To get the card to fit within the ATX specifications and ensure that the reference cooler could handle the heat of two GPUs whilst still being only a dual-slot solution, ATI had to keep the core speeds quite low.

Sapphire have dispensed with the standard cooler and so does it allow for greater clockspeeds and finally unleash the performance the 5970 has promised?

Absolutely. If you'll cast your mind back to the 5970 speeds you will notice that Sapphire have managed to get a 175 MHz increase in core speed and around 200 MHz faster on the memory. An absolute quantum leap forward in speeds compared to the standard design.

Time to take a look at the card in all its glory.

Wow. I'd love one of those for my system! I didn't expect it to overclock THAT well!

By the way, I see the award images have changed? (atleast for the performance award?) I like it, looks nice Quote

Yes indeed the awards have all been updated to match the new OC3D logo. If you think the performance one is lush, wait til we bring the others out.Quote

great review but I really can't understand why in crysis warhead the asus ares kicks the ass of the toxic in the minima and average FPS even in stock clocks - what's going on here guys? Quote

Couple of things explain that. Firstly the Toxic had a few less CPU clocks to handle the Physx, and the Toxic is a 5970 whereas the Ares is twin 5870s.

So the CPU will account for most of it, and the tiny extra theoretical grunt of the Ares gives us the few extra. If you look back at the Ares XF results you'll see that Crysis is pants no matter how much hardware you have. So really take it with a pinch of salt.

Hmm. Is it me or does that cooler either -

A. Completely rip off the Arctic Accelero Xtreme

B. Use an Arctic Accelero Xtreme.

'cos from where I am sitting it has to be one or the other.Quote
