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

Features

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?

Benchmark Results: Crysis 2

This is perhaps the most interesting game to analyze. Because the charts are sorted by the longest bars—those achieved under DirectX 9—both new Cape Verde-based boards finish at the bottom of the stack.

However, whereas everything else excels in DirectX 9 and takes a big hit with DirectX 11 enabled, the Radeon HD 7770 and 7750 both run faster under DirectX 11.

As such, the Radeon HD 7770 turns in quicker DirectX 11 numbers than AMD’s Radeon HD 6850, while the Radeon HD 7750 beats the old Radeon HD 5770.

Unfortunately, by the time Cape Verde’s afterburners kick in for that performance boost, frame rates in Crysis 2 are too low for an enjoyable experience. Really, you’d want something like a GeForce GTX 560 Ti in DirectX 9 mode.

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

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

    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.
