New Radeon Pictures Leaked: HD 7770

First pictures of AMD's mainstream card, HD 7770, have now been leaked online. This card is the first major upgrade to the HD 5770 in two years, since the HD 6770 was just a rebrand. It features the Cape Verde GPU, which replaces the Juniper GPU used in the HD 5770/HD 6770. The card looks somewhat different, with a large fan sitting on top of the GPU, blowing directly onto it and the card's length is the same as the HD 5770, at around 8.25 inches.
SPECIFICATIONS
  • Three display outputs, DVI, HDMI and miniDisplayPort
  • Single Crossfire connector for 2 cards max
  • The reference PCB has four GDDR5 memory chips, implying a 128-bit memory interface
  • Single 6-pin PCI-E power connector
  • Around 100 Watts power consumption
Finally, as can be seen by the second picture of the naked PCB, the Cape Verde GPU is physically quite small for this level of performance. The old Juniper XT is 166 mm², the GF116 is 230 mm² (NVIDIA GTX 550 Ti), while this GPU looks like it's under 150 mm². Judging by the sizes of the fan and the GPU, this card should be quiet and have good thermals.

This is what should have gone into the Wii U instead of a creaky old R770. I'll bet this is what will end up in the Xbox 720.

qubitThanks for posting these, but those slides have been debunked as fake - that's why you've not seen them here on TPU. I love the awesomness comparison. :laugh:
Whats more funny is that the awesomeness graph have the chinese word "boasting" watermark on it.

lol, a world where nvidia beats AMD what a laugh, oh wait no,

the 760 needs 180 watts and 2x 6 pin
the 770 needs 300 watts and 2x 8pin
the 780 needs 500 watts and 3x 8 + 2x6 pin
the 790 needs ∞ watts and 5x 8pin


enjoy running a dedicated line from the breaker box for your pc nvidia fans

With zero information on hand, that graph pretty-much says a special-olympics runner is more "special" than a standard olympics one. Take your pick.

btarunrVery nice. So it's not a rebrand. VLIW4 1024SP, 128-bit GDDR5 high-speed (that's 1350 MHz) should make this an incredible deal.
Where did you get that?

Nowhere. It's my own speculation.

It is the same thing card as the 5770. Its a rebrand just like the 6770 was. So where is the freaking upgrade at? Same damn specs.

:cry:

:cry:
:confused: What?
Uhm, no.

The HD 5770 has:
SPECIFICATIONS
  • Three display outputs, DVI, HDMI and miniDisplayPort (the HD 6770 added support for HDMI 1.4a)
  • Dual Crossfire connector for 4 cards max
  • The reference PCB has eight GDDR5 memory chips with a 128-bit memory interface
  • Single 6-pin PCI-E power connector
  • Around 130 Watts power consumption
Besides, the HD 5770 is a 40nm Juniper-XT core and the HD 7770 is a 28nm Cape Verde XT (Graphics Core Next Gen). Also, the HD 7770 is supposed be a PCI-e 3.0 card, while the HD 5770 was/is a PCI-e 2.1 card.

I see a lot of differences. It's not a rebrand.

I was really hope this chip and not need a 6-pin, but that does kill it for OC'n.
Might still be that they skip the 7750 (do we really need it?) and just release this 28Nm (cutback) as the 7670 maintaning the chip to 75W, for those that have and OEM box and quality 300-350W PSU.

Hmm, I thought only the Tahiti based cards were built off GCN, and the rest were VLIW4 like the Cayman series (aside from the low-end rebrands remaining VLIW5)?

No.
The tahiti, the *confidental, ryhims with (damn! nothing... oh well) * and the Cape Verde are all based on CGN according to... rumors based on leaks from AMD :D
