Radeon HD 7700 Series Specifications Surface

EpicShweetness · Feb 11, 2012

Anybody notice the TDP of 55w for the 7750? Sooooo basically since the PCI-E lane can give 75w of juice is may very well need no extra power, can you say HTPC :toast:

The 7770 has a 80W TDP, hmmmm. lower the clocks to like 850-900 and with a custom PCB no extra power as well? Oh this sounds amazing!

So what? i bought it at 140 bucks man......i don't care if it started at 299......
And......again......what can you buy with 140 bucks right now that performs 100% better than my 2 and a half years old vcard?

5870..... You can get a used 5870 for $140 and it's damn close to double the performance of your 4870

1280 sounds too good ... coming from 640

The SP count might be too good, but please bear in mind that this is a 128-bit card. AMD need to pump SP count and high memory clock.
So, expect the 7770 to be a bit faster than 6850. Between 6850-6870, in my opinion.

1280 SP for 7770, 1408 SP for 7850, and 1664 SP for 7870, that's my scenario

Who's speak the truth? Well, like always, just wait and see...

why would the 7770 be faster then a 6850 when AMD's own slides dictate its performance is between 6700 and 6800 performance AMD's own performance estimates place the card around 6790 / 5830 performance regardless of specs.

I can tell you that these are based off of a somewhat educated guess. It isn't correct.

Ah right, just saw some "leaked" bench by chiphell and you're absolutely correct, it is between 6790-6850.

I'm i the only one that thinks these cards should be on par with 6850 and 6870 in performance and cheaper?, i mean why release them at the same price if they perform worst? what the f*** is going on?
