AMD Radeon HD 6770 and 6750 spec sheets emerge

AMD Radeon HD 6770 and 6750 spec sheets emerge, give NVIDIA cause for concern

Alright AMD, we still haven't forgiven you for burying the glorious name that was ATI, but if your next GPU refresh is as mighty as these numbers indicate, we might at least let you in from the doghouse. A slide detailing two flavors of the upcoming 40nm Barts chip has sprouted up from two independent sources online, and it shows some appreciable gains between generations. The new HD 67x0 cards appear manifestly speedier than their predecessors -- with faster clocks, more texture units, and more ROPs -- but the fun really gets going when you compare them to the HD 5870 and 5850, AMD's previous high-end cards. Memory bandwidth and pixel fillrate are identical between the HD 6750 and 5850, while the HD 6770 even manages to beat the formerly glorious 5870 in a couple of areas. Of course, this is all still unconfirmed information, but considering that Barts is only an "upper midrange" chip that's already stepping on the toes of last year's finest, we feel safe in expecting some pretty big things from the flagship Cayman silicon when it lands -- which will be soon if all these leaks and rumors are anything to go by.

Would love to see some spec about energy consumption !

[watchthisspace]

This should be interesting.

Impressive numbers for half gen upgrade. Looking forward to see actual benchmarks.

i fail to see, from that chart, how the 6770 is going to be faster than a 5870... or should i be comparing the 5870 to something like a 6870? :blink:

Yes, compare the 6770 to the 5770 and wait for the details on the 6870 before comparing something to the 5870.

It looks like that the 6770 will fall between the 5850 and 5870 performance wise. Also looks like the 6750 should have around 5850 speeds. It is nice to see AMD midrange having 256bit memory interface this time around. I am expecting these to put out some good numbers, and hoping to be priced accordingly as well.

Other than the pixels fill rate, these cards appear slower ?

[ShiFteDReaLitY]

Also, the other photo shows the wattage. 114w for the 6750 and 146w for the 6770. If its correct it seems great considering the specs of the cards. :)

No, look again, compare the 6770 to the 5770, most of the values are something like 70% higher, granted that won't translate directly into 70% better performance, but you get the point.

Purchased a Palit GTX460 Sonic OC edition recently and I am extremely satisfied (overclocks like a dream :D ) . Although I won't be changing the video

card anytime soon, it will be interesting to see how nVidia responds...

[qdave]

Luckily i have 5850, which renders it useless to upgrade :p Will see what 6850 will be like though.

I too am interested in how nVidia is going to respond to this, the GTX 480 from what I have seen is not significantly more powerful than the 5870 (the 480 is better, don't get me wrong, but not as much as I expected given how much later the 480 came out), so it will be interesting to see if nVidia has anything up their sleeve to compete with the 6000 series.

So, for 5750 <-> 6750 it's +28 W for a 0.6TFLOP performance.

That makes it 32% more consumption for a 60% performance gain. Not bad.

Sorry I was comparing to the 58xx cards

Raw TFLOP increase doesn't translate into actual performance gain in games though. It may translate to actual performance gain in something like F@H, but in terms of games it won't be a 60% increase. Either way its still a nice improvement considering this isn't the new chip that the next series will bring.

let me guess

6870 gonna pick over 2000!!!!!! shader core :p

[djzic]

Wow... they'll own my 5830!

I'm probably going to get a 5870 after the 6xxx cards come out and the prices drop :shiftyninja:

[Motoko.]

My best friend went w/ a GTX 460 but I'm still waiting trying to be patient before I build my next machine, I want to grab a 6770 if the Cayman is too expensive

I also wonder how good Crossfire will do on AMD's new socket.

[Blackhearted]

Hmm.. If the prices are good, the 6700 series just may get me interested to upgrade from my current card.
