Can you guys define, "late to the party" for me please? I can understand if Nvidia announced a GT300 launch in June, July or August and it's still not here yet. But there have been no such announcements by them at all. You are only considering GT300 late because ATI is launching (pre-launching) R8xx soon. And last time I checked, there is no rule saying both companies have to launch at the same time, and if one does, and the other doesn't, the other is late.
The only thing you can accurately construde from current events is, ATI is launching R8xx before Nvidia is launching GT300. This doesn't make GT300 late. When we get an official launch date for GT300, and that time comes and goes, THEN you can call GT300 late.
I'd call it (and this can apply to product lines from either ATI or nVidia) late if it is released well over a month later than whatever product it is competing against. For instance, if the GT300 was released 6-8 weeks after the Radeon 5xx0 series then I'd call it late.
A 4 week window of opportunity is great for ATI but I don't think it will make a significant dent unless ATI's new GPU's are better than nVidia's new GPU's. However, a 6-8 window (or more), would be pretty substantial. Keep in mind I'm not in any way shape or form saying the Gt300 will be that late. All of us really have no clue. Just illustrating an example. Another is how the X1800 was expected to release before whatever nVidia's new GPU was at the time. Because of bugs, the X1800 was released well after it's competing GPU. The X1800 wasn't a bad GPU but being late certainly did hurt ATI.
One of the reasons (I think) AMD is able to release R8xx so quickly, is that R8xx (I think) is basically 2 R770's in one chip. Anyone who has seen the schematic photo for Cypress:
Cypress Architecture Schematic
You can see that there isn't one big core. It looks to me like they took 2 40nm 4770's (with the exception of 800sp instead of 640) and "glued" them.
"Glued" being a crude description, I'm sure there is more elegance to the design than that.
Anyway, A 4770 had a 128-bit memory interface. You can see each "core" in the schematice has 2 64-bit registers for the 256-bit total between both "cores". Also explains the doubling of everything. 800>1600 sps, 16 to 32 ROPs, 40 to 80 TMU's. This could also have been a contributing factor to the 4770 shortage for a while. Dedicating most of it's 40nm cores for Cypress, but I don't have any data to back this up. Grain of salt.
I understand what you're saying but I don't think it will be that big of an issue if they actually did so. While it's not the most elegant or efficient solution it can be made to work. Intel essentially did the same thing with the Pentium D by slapping two P4's together. This staved off AMD's advance long enough for them to come up with a "true" dual core CPU. With the massive parallelism of GPU's I think "duct taping" two older (though updated) GPU cores might not be as bad as it sounds. There will be a performance hit for overhead but it should provide updated performance. Bottom line is performance, not elegance.
Also, I don't think we can make a claim that the GT300 is "new" while the Radeon 5xx0 series is "derivative" until we see more of the GT300 and Radeon 5xx0 and what each does differently or better than it's respective predecessor from a hardware standpoint. All of that will likely be dissected by January '10 but for now, we simply can't say. Too little information.
funny how amd's old argument against intel's q6600 is now being used against them...
"but, but, q6600 is just two e6600's slapped together with duct tape, glue, and paper clips" - amd fanboi
"it's also about 17 bajillion times faster than your piece of shit monolithic quad core that is later than hell and has to be slowed down 10% via a bios update to even work" - pat gelsinger
"um, but ours looks cooler in a diagram" - amd fanboi
