HD 7770 & 7750 to be the cheap 28nm GPU of the lot early next year

For those of you who thought they had to wait longer to be able to obtain the more affordable section of AMD’s Radeon HD 7xxx series, well, you might get what you wanted a little earlier.
How much earlier you ask? Well if you can hold onto your wallet until February, that’s when it’s all planned to launch.
Starting of with the cheapest of them, the HD 7750, based on Cape Verde PRO, it’ll be clocked at 900 MHz with 832 shaders, 52 TMUs and 16 ROPs. The 1GB of memory will be clocked at an effective 5.0 GHz for a total of 80 GB/s of bandwidth.
While not offering performances comparable to the 7900 series, it does over quite an affordable price at $139.
Next up the ‘food chain’ is the HD 7770, this time based on Cape Verde XT, it should also be clocked at 900 MHz, feature 896 stream processors, 56 texture units and 16 ROPs. The memory is trimmed to a 128-bit interface, offering 1GB of memory clocked at 1375 MHz, 5.5 GHz effective, the bandwidth is at 88 GB/s.
Offering a small boost in performances, this version will be for 10 bucks more, $149.
Now, between the ‘entry’, and the ‘extreme’, there’s what we could call the ‘mainstream’, the Pitcairn cards will be the model to go to. The Radeon HD 7870 and HD 7850 will feature a higher memory bus of 256-bit, as well as some higher clocks, they will sell for $299 and $249 respectively.
For all we know, all the cards mentioned above should be introduced in February, but we won’t know that for sure until AMD decides to reveal them themselves.
