AMD Radeon HD 6770 and 6750 spec sheets emerge, give NVIDIA cause for concern
Not a year has passed since HD58xx series was launched, Amd is already planning to release yet another generation of gpus, straight from hells heart itself:

As you can see HD6750 has 280x4=1120 shaders, making it slower than HD5850 but faster than HD5830(as processing power indicates), has TDP of 114w(basically allowing it to run with just one pciex6 connector)therefore it will trade blows with GTX460.
The 6770 is a hell lot faster than HD5850 with 1280 shader only, this is probably due to the new shader architecture which happens to a be a lot faster and efficient than the previous shader architecture, the new card will also have 146w TDP being very cool indeed, the card will also have a 900MHz default clockspeed, making it history's fastest GPU, although TU will decrease but due to new architecture the texture/pixel fillrate is also higher than HD5850.
The new products will PROBABLY be placed like this:
HD6970-------------------------->GTX480 SLI
HD6870(possible 1920 shaders)--->GTX460 SLI
HD6850------------------------->GTX480
HD5870------------------------->GTX470
HD6770------------------------->(unreleased GTX460 with 384 shaders)
HD5850------------------------->Fill gap between HD6750 and GTX460 384
HD6750------------------------->GTX460
HD5770------------------------->GTS450
HD56xx------------------------->GTS430
Looks like HD5830 will be eol'd, the initial release will be HD67xx only, HD58xx will continue till Q1/Q2 2011 when HD68xx wll take over and compete with Kepler.
PS: This is pure speculation, but a few sources are claiming it to be true, while I doubt the shader numbers and clock speed but if they deliver nVidia will die(which would suck), they need to do what they did to the GTX460 to the GTX480(remove ecc and stuff) and get nice gpus out, competition drives the market, its the GTX460 that forced these cards to come out, we need more.
Prices are not revealed or leaked yet, but 67xx series will be a tad bit higher than previous gen HD57xxs.

Or will the performance will be increased with WHQL drivers, eh?
