AMD is saying the new card is 30% smaller than Titan, making the new card have a die size of 385.7mm^2, an increase of just 5.7% over the 7970.
512 bit memory bus confirmed, 2560 or 2880 stream processors still up in the air?
512 bit bus anyone?
If it really is faster than Titan this is a major step for AMD in the performance density of their parts, this suggests a major architecture change and not a simple refresh.
In the previous generation the 7970 GE was around about the same performance as the 680 (5% faster with the later clock speed bump) but the 7970 was 365mm^2 verses 294mm^2 of the 680. The Titan is 551mm^2 and only about 40% faster on average (sometimes its 90% faster) in performance than a 680. AMD is saying the new card is 30% smaller than Titan, making the new card have a die size of 385.7mm^2, an increase of just 5.7% over the 7970. Yet the claim is that this will deliver a performance boost of 35% or more in order to equal and then exceed Titan.
That is a significant jump in the performance density of AMD's card, far greater than any jump they have made in their recent history, far greater than any manufacturer of GPUs has made in quite some time. I have always felt the 7970 underperformed for its die size, a mere 5% quicker on average than a 680 with a refresh and clock speed bump and some 24% larger but at the same time it had the compute performance and the memory bandwidth the 680 never had, I can believe that costs 24% die size in the same way that 680 to Titan is an 87% larger die and only brings 40% extra performance. Such a jump for so little die size increase seems unlikely.
For all you enthusiasts out there, better start praying there aren't more mem chips on the back of the PCB...

Yeah I thought the reverse was (almost) confirmed, SP = 2880 and memory bus 384 bit . Rumors are floating.
Well apparently the rumor was true, AMD Hawaii GPU has (supposedly) 512-bit interface and 4GB memory according to leaked photos.
AMDs Radeon R9 290X equipped with Hawaii XT GPU is said to have at least 2560 Stream Processors. Some claim it will have 2816, which is not exactly confirmed. In fact the information we have indicates that the full Hawaii GPU will go straight to FirePro model, whereas the 2560 edition will be used with the flagship Radeon. Thats the rumor of course. I could not verify anything because AMD is very quiet about their new release.
It doesnt take a lot of effort to count the memory modules. You can easily find sixteen 256MB modules with a total capacity of 4GB, but thats not all, since the PCB could provide additional space on the back, with dual-sided memory, 8GB does it sound good? Nevertheless, 4GB memory size obviously suggest 512-bit memory bus.

this seems to be Hawaii and looks like AMD has gone ape shit crazy on the memory bus width with 512 bits. wow I am blown . :biggrin: if AMD has fit 2816 sp with a 512 bit memory controller with 48 ROPs into 430 - 440 sq mm thats some insane transistor packing density. 25th september can't come soon enough.
Here if the pictures are true.
16 x 32 = 512
IIRC random pictures on this internetz do not a truth make.
Yeesh, I wonder what Nvidia is thinking right about now...
I'm guessing 20nm and Maxwell can't come soon enough for them.
