As much equally we've railed against Nvidia in recent times for confusingly re-branding graphics cards and GPUs with newer serial numbers without changing silicon, AMD is non balky to the practise either. The unproblematic fact is there is well-nigh no difference betwixt its HD 6770 Vapor-Ten and the former schoolhouse Hard disk 5770.

Nvidia has done this before, re-badging the excellent 8800GTX multiple times, each vaguely dulling that excellence as it emerged. Offset it became the 9800GTX and so subsequently the GTS 250, with very little modification.

Almost the same has happened here with the HD 6770 coming out with the exact same silicon onboard, in fact AMD almost seemed a little sheepish about the launch of this card and didn't really seem to make any dissonance about it at all.

Despite the 6-series naming update for the card though vendors don't seem to be asking for whatever more than the standard new HD 5770s yet in the marketplace.

Though realistically it's going to impale whatsoever second-hand market place of the HD 5770 as most people will automatically assume that the card with the higher number is going to be the faster fleck.

If you look at the specs of both the Sapphire Hd 6770 and XFX Hd 5770 at that place is almost no deviation at all.

They're both running the aforementioned Juniper GPU, with the aforementioned graphics core configuration. The but slight alter on this VaporX version is that the HD 6770 hither is running slightly overclocked at 860MHz versus the Hard disk 5770's 850MHz.

Tiny clocks

In practice that means adjacent to nothing in the benchmarking stakes, although y'all'd hope the combination of factory overclock and funky, third-party cooler would make for a bit of an overclocking monster.

Unfortunately there doesn't seem to be much headroom left in the ageing Juniper cadre, so there really isn't much more you tin can get out of this newer carte over the older HD 5770.

Compared with the XFX card this is likewise dual-slot so it's going to hogging a lot more than chassis infinite compared with its compadre. That funky, VaporX cooler though does an impressive job of chilling the flake, dropping the temperature under load from the 73C of the XFX Hard disk 5770 to a far more reasonable 64C.

The consequence of the extra cooling ability and actress core clock speed all the same is a surprisingly large increase in the amount of juice the HD 6770 seems to require to go along running under full load. At 220W information technology'due south got a very loftier power draw.

Nosotros'd recommend the single-slot XFX Hd 5770 over the HD 6770, but and then those cards are going to become more and more scarce. And so if there'south no HD 5770s available, and you don't fancy going down the second-mitt route, then the HD 6770 is a worthy substitute.
