The days of the HD 6870 are numbered as today we see the arrival of the new sub-$200 GPUs from AMD, the HD7770 and HD7750. The stock HD 7770 run at 1GHz with 640 stream processors, 40 texture units and 16 ROPs and the 1GB of memory rides on a 128-bit bus at 4.5GHz. The stock HD7750 has a slower core, running at 800MHz and a lower stream processor count of 512 as well as only 32 Texture units, with the memory subsystem unchanged from the HD7770.
Those who were disappointed by the lack of custom coolers and factory overclocks at the release of the HD 7970 will be happy to see the variety of HD7700 series cards. For instance [H]ard|OCP reviewed the XFX R7770 Black Edition Super Overclocked which has a custom cooler, a 120MHz overclock on the core and a 300Mhz on the memory, effectively 5.2GHz. [H] proved that there is more memory headroom available in this card, adding another 1.1GHz without needing to adjust the voltage. For those who are willing to risk upping the power there might be even more speed possible from this card.
You can also catch Ryan’s review of the same card as well as an MSI version and a stock HD 7750.
"Today marks the launch of AMD’s Radeon HD 7700 series of GPUs in the sub-$200 bracket. We’ve got a retail XFX R7770 Black Edition Super Overclocked video card just itching to show us what it can do. Will this Radeon HD 7770 based video card hold up to the likes of the Radeon HD 6870 and GeForce GTX 560 Ti? You may be surprised."
