AMD Radeon HD 7770 and 7750 GPU Reviews

How We Configured Our Test Systems: We tested the graphics cards in this article on an Asus P9X79 Deluxe motherboard powered by a Core i7-3960X six-core processor and 16GB of G.SKILL DDR3-1600 RAM. The first thing we did when configuring the test system was enter the system UEFI and set all values to their "optimized" or "high performance" default settings and disabled any integrated peripherals that wouldn't be put to use. The hard drive was then formatted and Windows 7 Ultimate x64 was installed. When the installation was complete we fully updated the OS and installed the latest DirectX redist, along with the necessary drivers, games, and benchmark applications.

Unigine Heaven v2.5 Benchmark
Pseudo-DirectX 11 Gaming


Unigine Heaven

Unigine's Heaven Benchmark v2.5 is built around the Unigine game engine. Unigine is a cross-platform, real-time 3D engine, with support for DirectX 9, DirectX 10, DirectX 11 and OpenGL. The Heaven benchmark--when run in DX11 mode--also makes comprehensive use of tessellation technology and advanced SSAO (screen-space ambient occlusion) It also features volumetric cumulonimbus clouds generated by a physically accurate algorithm and a dynamic sky with light scattering.


The new Radeon HD 7700 series cards offered middling performance in the Unigine Heaven benchmark. The Radeon HD 7770 has no trouble besting the Radeon HD 6790 and GeForce GTX 550 Ti, but trails the GeForce GTX 560. The lower-priced Radeon HD 7750, however, trailed all of the other cards, with the exception of the previous-gen Radeon HD 6670.

I think that these cards will do well. The x770 cards in particular have been well received in the past and I see no reason for that to change.

I got a Diamond HD 5770 1GB(my first GPU and still is) When i bought this baby i was just amazed with its performance and price one year ago. I've never had a problem with it since then.

The Radeon HD 7750 looks ugly!

The Radeon HD 7770 looks great + its performance and power consumption just make it a ideal graphics card---I think I'm getting this one soon.

The performance is not a surprise, I expected that from AMD YAYYYYYYYYYYY

You can't be the prices for what is currently available at that power level. What is sad is to see a new gen product go head to head with a previous gen tech from team green. I expect more from AMD.

Did you expect the 7770 to beat the 560?

I'm with Omega.

This, in my opinion, was not a good launch. Right now a 6850/6870 or a GTX 560 are the much better deals in this price bracket (look for the rebates).

I figure that eventually AMD will soon EOL the 68xx series, and then the prices of these cards will drop: I think they did something similar when they launched the 6xxx, because the 5xxx series were still around and were giving much better performance for the same price. Then they will be convincing, esp for those gaming at below 1080p resolutions.

Agreed, A lot of sites are saying that the 77x0 cards are 90% of the performance of a 6870 for 90% of the price. So technically if it weren't for better power efficiency on the 77x0 cards your best bang for the buck is with the 6850.

The stated price points are their worst enemy here. (shooting themselves in the foot)

Yes, the cards perform well, and stay fairly cool too, but they are not high end parts and shouldn't be priced that way.

These will be a consideration for me when prices come down a lot.

Until then,..................

I don't think you can call $159 the high end of the price spectrum, seeing how 580's and 7970's are $500 cards.

I'd say this card would fall into the mid range for AMD's video cards. The x400 and x500 entry level. The x600 being kind of an odd child I'd a call mainstream class, and the x800 series filling the gap between the high end and mid range cards.

While I thought they were nice cards; there are better deals as other members said. Granted I thought they priced it well and for what they have, it is a good deal but I'm doubting if AMD is losing it in the pricing.

Still, good cards, good review; glad to know they're filling these product tiers as quickly as possible; in case NVIDIA launches the heavily expected onslaught on them. Looks like AMD's still able to put up good GPU's.

I'm a little confused, shouldn't the comparison be between the 6770 and 7770. The 6870 is the next step up the ladder.

Edit: After a quick look on the egg I get what the rest of you are saying. While the 7770's main competition at it's price point is the 550 TI, it is possible to find a few 6850s and even an off brand 560. Moving up just $10 places you firmly in 6850 territory, and it's hard to believe the average Joe would balk at an extra10 spot. The case for going with a 560 is a little murkier though as they don't show up with regularity until you hit about $185, and I can see some deciding to spend less.

I don't think they would have to make much of a price cut though. Somewhere around $139 - $149 would be just right.

But then again, with the 7770's  performance falling in between a 550TI and a 560, shouldn't it's price also?
