AMD HD7770 & HD7750 Roundup: Sapphire, XFX and HIS

Aliens V Predator has proved to be a big seller since the release and Sega have taken the franchise into new territory after taking it from Sierra. AVP is a Direct X 11 supported title and delivers not only advanced shadow rendering but high quality tessellation for the cards on test today.

To test the cards we used a 1080p resolution with DX11, Texture Quality Very High, MSAA Samples 1, 16 af, ambient occulsion on, shadow complexity high, motion blur on. We use this with most of our graphics card testing so results are comparable throughout reviews.

This is a very intensive Direct X 11 game which demands a lot of power. The single HD7750 cards can't maintain smooth frame rates at these settings, dropping below the 20 fps mark from time to  time. The HIS HD7770 GHZ Ed IceQ X manages to maintain smooth frame rates, dropping to the borderline a few times during our testing.

When both solutions are configured into Crossfire, the results are much stronger. Two AMD HD7750's in Crossfire manage to outperform the high performance Nvidia GTX570 from the last generation.

  1. Wow, that Sapphire card is really good. I had imagined I would get a prodigy case later this year and get a small video card for it ,just for video acceleration and image quality.

    This looks the card to get.

  2. I admit, you got me there.

    i was expecting the HIS or XFX to win this, but you focused on EXACTLY the right points. power consumption, noise, size, lack of power connector etc.

    Great job from sapphire, exactly what i need for my system, im using onboard and it sucks so badly for HD video. people dont understand the IQ differences between Intel on a CPU and a dedicated AMD card like this. its night and day. especially for colours and noise reduction options in the panel.

  3. A HD7770 or GTX460 is more than enough, even today, for 1080p gaming. people get a false idea that a 7970 or 690 is ‘needed’. those are three screen solutions now. save the money, pick up one of these cards, classic little cost effective beasts.

  4. Not sure im a big fan of these cards, but the sapphire model makes sense. im still wanting the 660, just trying to make sure I dont cripple myself for next month as I need to eat too.

  5. Some good overclocks, but I agree, why did they reduce the shaders from 800? typical fing stupid AMD at times. they could be doing so much better if they had people making decisions who understood the gamers.

  6. I like the HIS card best im afraid, if they hit £99.99 count me in for my second system.

  7. These aren’t good enough for 1080p gaming, I want 60 fps, sorry. but good pricing now for people without the cash for a £200 card,. thats the sweet spot.

  8. Am I missing something?

    They are releasing ‘new’ 7750’s at 900mhz+? havent they been out for months already? you guys reviewed many.

    bonkers AMD move. just drop the price, dont re-release them with bios updates. seems XFX were left out of the loop. Nice black reference edition :p

  9. I bought a Sapphire flex 6770 flex from the last generation and its still good. I dont use AA and I have my system into a 37 inch tv. runs well.

    Dont get sucked into the hype of needing 120fps for gaming, its bollocks.
