Sapphire HD4870 512mb DDR5

Features
 
Normally we at OC3D don't write about the 'features' of a graphics cards unless the card warrants it by a leap in technology. This is one such occasion.

 
Perhaps the biggest departure from the R600 series core is the introduction of what AMD likes to call One Tera or 'TeraScale GPU engine'.
As the name suggest the card is theoretically capable of over 1 trillion FPO's per second i.e 1 teraflop all the while utilising effiency and affordability in its transition allowing the consumer to benefit from lower costs. The 55nm process employed by AMD should in theory, make the GPU more effieicient, so not only will it run cooler but it will be cheaper to produce. This is an achievement in iteslf but the advances don't stop there. Without going to far into the specifics of the Terascale engine, it has been re-designed from the ground up making better use of the GDDR5's higher bandwidth available by granting each of the memory controller hubs its own cache, so while it may have a physical 256-bit memory interface, the increase in badwidth is actually on a par with a 512-bit interface. This, ATI calim, has enabled the 4000 series of cards to perform much better when AA is applied in comparison to the 3000 series cards.

Power Requirements
 
As graphics cards are getting faster and faster we are seeing the introduction of more and more power connectors to feed the required power to the cards. Long gone are the days when a PCI slot could power a card, we are now seeing upto 14 PCIe (6+8) pins being used for the high end cards and you can double that should you wish to go with SLI/Crossfire, or if you have Chernobyl tucked away under your desk you may want to go for TRI or even quadfire!  The 4870 fortunately makes do with 2x 6pin PCIe power connectors requiring 75w each and as such Sapphire recommend a 500W PSU for a single card, with a 600w minimum requirement for Crossfire based setups. So the power requirements are not too drastic as any gamer worth his salt should have a 500w+ PSU.
 
Obviously, depending on your setup you would be wise to opt for a bigger PSU as it's always better to have that little extra available, especially if you like to dabble in the dark art of overclocking.

Did u review that? Coz it was damn good!

However I thought that the 4870 was meant to outperform the gtx280

Naaaaa man it matches the 260 mostly.

Obviously varies on the odd game.

Good review, seems like a good card, nice to see it still performing well at high res and AA, as you said in the review it didn't cripple as the 3870 did.

Nice review once again, Looks like a damn nice card.

Cheers m8. Sadly the 4870 can't really hold a candle to the GTX280 - leave that to the 4870x2 .

that was one aspect of the card I found to be great - I half expected the card to perform very well but die once AA was applied, I was pleased to be proven wrong.

So the big question is what will you people buy?

The nVidia or the ATi

At this moment we want to have nvidia but we will buy ATI, 3 reasons for it : cheap price , good performance and stability.First and last one is what nvidia must work on ;] at least last one cause i dont think that nvidias cards will be at same price as ATI ever

I know that i`m mouning from few weeks about nvidias product but i have a major problem with my system going on SLI(or even without), after googling a bit and going thru different forums i have found many,many other ppl having same or similiar issues.

Sad but true.

I don't normally have a preference but NVidia, I usually go with whats best at the time which normally means NVidia. ATI however, are catching up pretty fast.
