AMD Readies "Tahiti" Based Radeon HD 7800 Series Product

AMD is reportedly working on a new performance-segment GPU in the Radeon HD 7800 series, based on the 28 nm "Tahiti" silicon (which goes into making HD 7900 series products). The so-called "Tahiti-LE" silicon could help AMD plug a hole between the HD 7870 GHz Edition and HD 7950, getting close to the performance-level of GeForce GTX 660 Ti, at a lower cost. According to a HT4U.net report, AMD is deciding against referring to the new chip as "HD 7930," since the 7900 series is already crowded with five models, and would rather name it something along the lines of "HD 7870 OC."

A similar approach was adopted by NVIDIA in the recent-past, when it created the GeForce GTX 560 Ti 448-cores, using higher-end GF110 silicon to create an SKU traditionally based on GF114. At this time, one can only speculate what the new HD 7870 specifications sheet could look like. Since "Pitcairn" already achieves clock speeds in the 1 GHz range, AMD is left with other features to tinker with. 1536 GCN stream processors seem like a middle ground between the 1280 SP-laden HD 7870 "Pitcairn," and 1792 SP HD 7950. Memory bus width is another component. The new desktop SKU could launch in mid-November. The new SKU could even be a "limited-edition" for the winter shopping season, much like the GTX 560 Ti 448-core.

You missed the 660, 660 OEM, 650, 640 OEM, 630 OEM, 620, 620 OEM, 610 and 605 OEM. And that's just for the 600 series of cards. Your brain overheating yet?
And you still can't remember Nvidia naming scheme. I will give you some tip. Lose attention to all GPUs under 640, because they are so slow, there is no reason to remember them.

You know what the difference between you and me? I know that 660 is slower than 660Ti. And 760 will be slower than 760Ti and so on.

i know this is far fetched but wouldnt it be kind of funny to see a dual core 7890 or 7870x2?

im wondering if the bit bus is 256 vs 384 meaning even distribution of data across all memory banks.

this is practically the same as having a 6790 which isnt necessarily a bad thing actually. This might verywell be the missing link for Crossfire between 78** and 79** serues boards

Amd has something up their sleeve with this card. They probably are doing this to get rid of stock. To really move the stock fast they will make some sort of shader unlock 7800 trifire something etc.
