AMD Radeon HD 7770 Pics, Specs and Benchmarks Leaked

By - Source: techngaming | B 59 comments

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.

    BenihanaMy GeForce 2 MX 440 just burned out. Guess this could be a good replacement.

    I don't think they make the 7770 in AGP buddy.

    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 precise

    @sseyler

    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!

    No but seriously this card will bring some great performance.

    Quad core i5 3550 with 7 series intel chipset? They use Ivy Bridge on this bench!

    I was going to buy a 6850 this march in my trip to US, I guess this one is going to a better choice for the money... ONLY if the price goes about $120-$130..

    Can I assume that due to the GPU change that it won't be Crossfire compatible with 5770/6770?

    The ASRock 775 Dual VSTA had PCI Express and AGP slots but had only 8 lanes. Can be done though.

    Achoo22AMD's new cards are complete failures, simply because they don't represent a true generational leap. The new 7850 should be faster than the existing 6850, especially if it's going to initially retail at roughly the same price. AMD has lost their bang-for-the-buck advantage in the video card market, and unless NVidia changes things up in a hurry, my next graphics subsystem will probably end up being integrated Intel in 2014 or so.Voodoo Rush->Voodoo 3->overpriced crap->6800gs->8800gt->HD6850->overpriced crap so far. Show me the next 8800gt, please, or lose me forever.


    I disagree. So far, their performance has been a convincing increase. Do you need a 100% improvement to call it a generation leap? If so, you will be disappointed with every generation. If the 7770 is almost as fast as a 6850, it stands to reason that the 7850 will be faster. How much faster, and what the price point will be is the real question. Also, they are not concerned whether they lose you at all.

    With the 6850 at ~$150, this card should be in the ~$90-100 range, assuming the 7850 will take over the ~$150 price point.
