Fudzilla reports that ATI’s Evergreen card will end up “1.6 times faster” (Read: 1.6 times as fast, please read update below) than the previous generation HD 4870. It is not mentioned which card exactly in the Evergreen family – but we will assume Cypress XT, which is the direct successor to the HD 4870.

The 1.6x rumoured is also expected to be a best case scenario, and in reality it may end up slower in few games. The Cypress chip was previously rumoured to include 1600 shaders, which is a direct 2x jump from RV770, with over 2 TFflops of processing muscle.

Fudzilla reports that ATI’s Evergreen card will end up “1.6 times faster” (Read: 1.6 times as fast, please read update below) than the previous generation HD 4870. It is not mentioned which card exactly in the Evergreen family – but we will assume Cypress XT, which is the direct successor to the HD 4870.

The 1.6x rumoured is also expected to be a best case scenario, and in reality it may end up slower in few games. The Cypress chip was previously rumoured to include 1600 shaders, which is a direct 2x jump from RV770, with over 2 TFflops of processing muscle.

Although a 1.6x increase is by any means a significant jump – given the buzz AMD is creating, and all the rumours about doubling of shader power, architectural improvements, one must have expected a more significant improvement.

On the Nvidia side, their response to the Evergreen generation is the GT300 card – rumoured to feature 512 “processor cores” (a 2.13x increase) and various architectural improvements, most significant being MIMD (Multiple Instruction Multiple Data) cores, a step forward from the SIMD functions currently used in GPUs. Given the nature of these rumours, the GT300 will end up faster than Cypress, but at the same time, it die will be much larger and hotter, and it is unknown if Nvidia can fight with a dual GPU product against ATI’s dual-Cypress Hemlock.

Again, all such rumours must be taken with a big bag of salt. Rewind back to RV770, ATI had everyone fooled – including Nvidia, who grossly underestimated RV770 performance. It will come as no surprise if Cypress does end up faster than the rumoured 1.6x, come 10th September, but this is the information Fudzilla reports for now.

UPDATE: As per the source article by Fuad, the phrase used “1.6 times faster” provides a certain degree of ambiguity. Technically, it should mean “2.6 times faster”, but in common speak, it can just as well imply “1.6 times as fast”. The other phrase used by Fuad is “1.6 times performance increase”, but that is equally ambiguous. However, a bit of Googling led to Fuad’s article from way back in December 2008, reporting about the Geforce GTX 295. As per the article, the GTX 295 would end up “1.7 times faster” than a single card. Naturally, a GTX 295 couldn’t be 170% faster than a single card, but 70% sounds like the correct increase. Therefore, it can be concluded that, according to Fuad’s use of the language, he most probably believes Evergreen will end up “1.6 times as fast as” HD 4870, as alluded to in the original article above. That is, if HD 4870 performance were 100 fps, Evergreen would churn out 160 fps. We apologize for the confusion. Fuad does not mention exactly which product from the Evergreen generation he is considering either. For comparison’s sake, it would make sense that he were talking about Cypress, which is the successor to RV770. Of course, that number is nothing but unsubstantiated rumour at this point, and we encourage you to only consider it as such.
