Sapphire Radeon HD 7770 

Released February, 2012
  • 1.1 GHz
  • 1 GB GDDR5
5.6 Out of 10

ASUS has decided to price their board at the AMD MSRP, so the added value is really added value over the reference design, since there is no price premium charged for it.

It features a 128-bit wide GDDR5 memory interface, with which it communicates with 1 GB of memory.

Reviews Word on the street for the Radeon HD 7770

In our testing we see excellent noise results from the HIS HD 7770 iCooler, making it whisper quiet in idle and barely audible under load - a great improvement over the reference design.

What People Are Saying Give it to me straight


You may combine up to two HD 7770 cards from any vendor in a multi-GPU CrossFire configuration for higher framerates or better image quality settings.

Even though Vapor-X was engineered for high-end cards, the company's exclusive cooling technology can really show its potential on this lower-midrange card.

You get right around 30 frames per second at 1080p resolution in modern games, with the detail settings cranked up high.

This efficiency is supposed to show in relative performance per mm² (taking the new 28 nm fab process into account), performance per Watt, and in more layman terms, performance to stream processor count.

AMD's latest graphics processor shows outstanding power consumption characteristics.
by techPowerUp! (Feb, 2012)
In this power state, the graphics card draws less than 3W of power, making it extremely energy-efficient.
by techPowerUp! (Feb, 2012)


A couple of judicious choices about where to reduce quality should provide a nice experience with almost any new game.
by Jason-Cross (Apr, 2012)
Both cards are similar at idle, but when you fire up a game, the difference is remarkable.
by Jason-Cross (Apr, 2012)
It’s fast enough for modern games, but just barely.
by Jason-Cross (Apr, 2012)


We can look at an individual game, like Crysis 2, and see that the Nvidia card is a good 20 percent faster.
by Jason-Cross (Apr, 2012)
For gaming this is very impressive, as XFX's card runs significantly higher clock speeds than the AMD reference board, which typically results in increased power draw - not so with the XFX HD 7770.

It is pretty much the reference design, at same clocks, using the same cooler, but also comes at no price increase.
by techPowerUp! (Feb, 2012)
The only drawback is that XFX charges a serious price premium for their card - $179 makes it difficult for the card to compete with other, cheaper, products that have been on the market for a while.
by techPowerUp! (Feb, 2012)
Nobody likes spending more than they have to, but serious PC gamers will probably want to pony up more than the $139 asking price for the Radeon HD 7770.

stupid assholes. know what your screen resolutions are.
Yeah! For me too! And Tomb Raider on Extreme but with lowered ssao.
It plays FC3 on ultra at 30 fps for me...
Works great for my needs !
This card really helped me on some games, i mean vanilla skyrim ran fine, but you put any enb with it and you get like 30 fps, its a shame it can't handle good graphics skyrim in high res. Its not the card i recommend these times, there is a a much better card for like a 50-75 bucks difference. You gotta be cheap to buy this card, honestly.
This card, in combination with my dual-core i5 and 8GB of DDR3, runs Battlefield 3 smooth on medium settings, Far Cry 3 the same. It even manages to play Skyrim smooth on high (Smooth to me is 50FPS+.). Add to that it's very low price point and low power requirement makes it perfect for the budget gamer who can't pay £200/$300 for a card.
