AMD Radeon HD 7770 And 7750 Review: Familiar Speed, Less Power
These are the lowest-end cards built using AMD's new Graphics Core Next architecture. Is 28 nm manufacturing, a fresh design, and new functionality enough to warrant upgrading existing value-oriented champs like the Radeon HD 6850 and GeForce GTX 460?
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.

Derbixrace the 7750 will be a GREAT card compared to the 6670 for those who have a shitty 300w PSU and wants a nice GPU.Reply -
phamhlam 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.Reply -
dragonsqrrl "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."Reply
I think you mean AES256. -
jprahman 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.Reply -
esrever Seems ok, New stuff ussually cost more. The 6770 being more expensive than the 5770, the 6870 being more expensive than the 5850 ect.Reply
I'd expect prices to go down once supply goes up and demand goes down. -
confish21 What a sad release. I'm not even excited for Pitcairn now! I foresee the $170 6870 to hold its own.Reply -
This is ridiculous. Man this sucks, i've been waiting for the 7770 since early last year, and this crap is what they release?Reply
What_were_they_thinking? -
wicketr Well....here's hoping for a good 7850/7870 release on March 6th. Not much here worth spending money on IMO.Reply -
buzznut 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.Reply
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.
