Given that Intel s increasing the EU count from 12 to 16,
plus a higher frequency, we can safely assumethat IB graphics
will be at best at a 160 SPs 6450 level.
True that it s significantly more than the 120 i first
estimated...
Now notice nowhere in this thread I've speculated how IVB's graphics will perform. In a general sense, you will probably turn out to be right. IVB's graphics might not beat Llano. But to see how it will really perform, we need to look at the details.
-Ivy Bridge's GPU being 30% faster than Sandy Bridge's graphics is very likely not an Intel statement, but a speculation from the source that leaked such info. 16 is approximately 30% greater than 12, so people who seen that must have concluded it would be 30% faster.
Unfortunately, the leakers do not have a brain capable about knowing something called a diminishing return. 33% increase in shaders alone have never resulted in 33% increase in performance, or even close to that. By the increase in EUs alone, I'm thinking we'll only see 20%. Now that's not a conclusion of how I think IVB's graphics will perform.
-Llano's graphics. Are you sure it'll perform like the 5570? How do you know it won't perform 10% less because of its peculiarities(eg. sharing the memory with the CPU)? Will it perform like the 5570 on Phenom II, or 5570 on Core i7? Overclocked best case scenario 5570, or reference 5570? History of integrated graphics suggests that the same graphics core using system memory resulted in 10-15% less performance than a dedicated equivalent. That's with all the fancy marketing acronyms added making it sound like the integrated version has the technology to perform even better than the dedicated memory version.
-Performance with specific games. You can have two products trading equal punches to each other but depending on the preference of the reader they will point out on benchmark that performs especially worse with one product and say whatever they endorse wins. Now with such a different architecture and direction
we will have such case with Ivy Bridge and Llano's GPU.
