AMD Radeon HD 7770 And 7750 Review: Familiar Speed, Less Power

Test Setup And Benchmarks

In the pages that follow, you’ll see the Radeon HD 7770 and 7750 tested against six other graphics boards. These six were chosen based on an initial price estimate AMD gave us between $99 and $199 for its two new cards. In retrospect, I would have rather benchmarked a GeForce GTS 450 against the Radeon HD 7750 instead of a GeForce GTX 560 Ti up top. Also, it would have been nice to have a Radeon HD 6790 in here. That card wasn’t available for testing though, so we have the venerable Juniper-based 5770.

Also, pay particular attention to the GeForce GTX 460. The card we’re using for comparison is a 1 GB board with a 256-bit bus. As you probably already know, Nvidia sells a 768 MB version of the card. Now, however, it’s also taking advantage of the GPU’s ability to address different memory ICs by shipping a 1 GB model on a 192-bit memory bus. If you’re not paying close attention and end up with that configuration, performance will be lower than the 256-bit card benchmarked here. It’s a sneaky move, but if you buy from a vendor that lists detailed specifications, you won’t get unknowingly duped.

    I hope the price of 7770 comes down to $130. That is where this card belongs.

    the 7750 will be a GREAT card compared to the 6670 for those who have a shitty 300w PSU and wants a nice GPU.

    stm1185These prices are terrible, even compared to the current competition and not the inevitable huge price drop to compete with Nvidia's next gen. 7770 giving less then GTX460 performance at $160, when in what 2-3 months Nvidia will probably be giving that performance level for under $99. 7770 is crap.

    Amd may be taking advantage of their unopposed release of the 7000 series to sell their cards at high margins. They may just be waiting for the new Nvidia cards to come out before they drop prices.

    If the 7770 is the same price as the 6850. I think we have the best value card right here. The 6850 was a great budget card but this card will change that.

    "Although other cards beat it in encryption and decryption performance, the Radeon HD 7750 easily secures a second-place finish in the SHA256 hashing test."

    I think you mean AES256.

    The fight shaping up between all these new AMD cards and Kepler is looking to be a good one. Time to just sit back with some popcorn and enjoy the show... while planning a new build for when the price war breaks out.

    Seems ok, New stuff ussually cost more. The 6770 being more expensive than the 5770, the 6870 being more expensive than the 5850 ect.

    I'd expect prices to go down once supply goes up and demand goes down.

    What a sad release. I'm not even excited for Pitcairn now! I foresee the $170 6870 to hold its own.

    This is ridiculous. Man this sucks, i've been waiting for the 7770 since early last year, and this crap is what they release?

    Well....here's hoping for a good 7850/7870 release on March 6th. Not much here worth spending money on IMO.

    This is unfortunate, considering the naming scheme. The 4770, 5770, and 6770 were/are all good budget cards that performed above where they were priced. Bang for buck has always been the draw here, but that 7770 is overpriced. Hopefully AMD will see this fumble; I agree at $120-130 this card makes a lot more sense.

    I'd actually like to see the HD 7750 at a lower price too, as we know these prices will drop over time but I still think this is slightly high for launch.

    In the monthly best Graphics cards you mention that AMD is dominating. I wonder why though. Are Nvidia's cards capable of maintaining a price premium because consumers are willing to pay a little more to use Nvidia drivers and extras like PhysX and 3d vision? Or possibly are their cards more expensive to manufacture and so Nvidia must raise prices to maintain margins and simply suffer reduced sales at those prices. Anyone know?

    I was hoping the 7770 would provide a little more umph. I'm running a 460GTX-SLI setup, and hoped that ATI... er AMD's mid-range bracket in Crossfire would provide a significant boost, worthy of an upgrade. With the 460 more than hanging in there at stock speeds, I can't see a dual-card upgrade in the future, unless Kepler just absolutely blows this up at these price points. Even the 7950 and 7970 are a hard sell with limited availability and price-gouging.

    AMD is like the Chicago Cubs. Even non-fans want them to succeed, but they can never seem to get their act together.

    I agree somewhat, but I don't think it's the enthusiast crowd they're targeting here. It's the OEM crapfest that pushes the latest trash onto unknowing consumers while slapping a gaming pc title on their box.

    AMD had an edge with the Cayman because its performance was unopposed in the single gpu realm. With these cards that's nowhere close to the truth. In the past you could at least expect to get new DX support newer shading support or anything that would give the current model a unique edge over it's predecessor. I'm just not seeing that with this release. Then to top it off AMD is continuing the trend they started with the 7970 of an over-inflated launch price. While that might have flown with the cards that were untouchable, it's not going to fly here when you can spend the same money for more peformance, period.

    I feel bad for pre-built pc buyers that are unaware of things like this, such a ripoff.

    scallywankerAMD's mid-range bracket


    Confused by the launch order and prices, I mistook this for their mid-range, and not their budget range. It's better, but not by much.
