AMD Radeon HD 7770 Pics, Specs and Benchmarks Leaked
With the HD 7970 set to release this month and HD 7990 & HD 7950 shortly after, we get our first leaked information on the HD 7770. It is the first upgrade to this series since the HD 5770 with the HD 6770 being a re-branded HD 5770.
ChipHell forum member bigpao007 has leaked some pictures and 3DMark results of the upcoming HD 7770. The HD 7770 is set between the current HD 6800 and HD 6700 series in AMD's graphics platform and is a more "budget" friendly GPU compared to the HD 7900 series. The GPU uses the new 28nm Cape Verde Southern Islands featuring the Graphics Core Next architecture.
The basic specifications of the card are as follows:
- 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 100W power consumption
The HD 7770 has the large cooling fan blowing directly on top of the GPU, which is a change from current HD 5770/6770 designs. The length of the card looks to match the HD 5770's size of little over 8 inches in length. The naked image of the PCB shows that the Cape Verde GPU is smaller than previous generation Juniper XT or even Nvidia's GF116 (Nvidia GTX 550 Ti). It looks like the GPU is under 150 mm2, while the Juniper XT sits at 166 mm2 and the GF116 at 230 mm2. This size decrease should help produce a nice-performing card that runs cool-n-quiet.
The setup used for the 3DMark Benchmarks consisted of an Ivy Bridge ES CPU – Core i5-3550K at 3.3Ghz and Z77 chipset-based motherboard, along with AMD Catalyst 8.940 RC2 driver.
3DMark 06: HD7770 (Stock @ 1Ghz): 18143 3D Marks (SM2.0: 6785/HDR: 8086/CPU: 6390)
3DMark 11 (Performance Preset): HD7770 (Stock @ 1Ghz): P3421 (3138 Graphics Score)
3DMark 11 (Extreme Preset): HD7770 (Stock @ 1Ghz): X1077 (965 Graphics Score)

sseyler So I'm guessing (without having to do too much digging due to laziness) that this card will perform somewhere around or below the HD 6850?Reply -
alikum sseylerSo I'm guessing (without having to do too much digging due to laziness) that this card will perform somewhere around or below the HD 6850?Below a 6850 and above a 6770. A "6830" to be more preciseReply -

My thoughts exactly :)
I went and looked at my own Sapphire 6850's 3DMark 11 score and it was a bit over 3600, so this new 7770 should be a worthy upgrade for anyone running the 5770/6770 cards. With a little touch of O/C it will be right up to the 6850's speed!
Now, if the price is right ... maybe around the $100 to $120 mark it will be a very solid performer! -
beetlejuicegr Damn, so i am sticking to 5870 and will change at 8000 ati...in 1 year or more..Reply -
de5_Roy only dual card cfx?!? me sad. performance looks promising.Reply
3 of these in tri-fire would be awesome.... i wonder if amd and oems will let tri-firing them.... -
theconsolegamer Look! It's an Radeon 560ti or a GTX 7970!!!Reply
No but seriously this card will bring some great performance.
