The GT300/Fermi Thread - Part 2!

[saaya]

Seeing how vast majority of programs, and even games are barely even optimized for 2 cores, you can imagine how much ingenuity this requires on GPU side.

the tasks that are performed on the cpu and gpu are completely different though, the cpus strength is serial work, the gpus strength is parallel work... thats why coding games or apps to use several cpu cores is just as much as a pain in the lower rear side as it is to code apps that use the gpu to perform serial work, which, most apps need at some point... thats why gpus get their own cache and get their task schedulers reshuffled and upgraded and will probably even get branch prediction, while cpus get avx and beefed up double pumped execution cores ala gpu... thats at least how i understood it...

show me a framerate comparison at the dragon now

oh god, i cant believe this low blow marketing actually works... you really care how cards perform in some synthetic highly unrealistic scenario? this reminds me a lot of memory benchmarks where one set is 2x as fast as another but you wont be able to find a real world app that shows a perf gain past .x%...

GTX 480 has 480sp, as charlie said,haha

mhhhh that increases chances for people to actually be able to find one, provided they have enough money and fast index finger reflexes to hit the BUY button fast enough when one shows up in the shops...

but it also means lower performance...
im sure that nvidia didnt like this... either yields were too bad or maybe they figured out that 480sps (8%) allow them to clock the card more than 8% higher (~50mhz) so perf wise it makes more sense... or maybe mhz gives more of a perf boost than more sps... that would make sense since 500sps is quite some parallel power that isnt easy to feed i assume...

Came across this and LOL'd

hahahah, that is hilarious
i wish more pr campaigns would be based on funny stuff like this... it doesnt matter what product you own or think is better, those clips are simply hilarious

Right. Even if there is only one working 512SP-Part on the Wafer, it doesn't make sense not to sell it.

thats provided it not only has 512 working sps but 512sps capable of running at decent clockspeeds AND being able to do so without triggering a thermo nuclear meltdown... jokes aside, it actually makes little sense to sell those parts as vgas... youd think that anything above 448sps would be sold as tesla cards, as they retail for 2500us$+... the only reason to sell those big fat gpus in retail as vgas is for pr purposes... which is confirmed by their, relatively, low volume...

AFAIK we don't even have a confirmed 480 PCB picture.

yeah we do... you didnt see it?

I wonder how many chips they have that actually work like that though, obviously only a couple but i wonder exactly how many

i think there are quite some, but how many can work at those specs at room temps and with acceptable cooling is probably very lower... 750mhz plus 512cores... im sure they have at least a hand full of those since they ordered 10k wafers, right? so even with 0.1% yields they would have 10 of those cards now...

Hmm. 3? One for Jensen, one for Igor. Jensen's is SLI.

pfff, igor gets a single gts240 card with 480 heatsink glued to it... as if hed even notice the difference...

so wait, the highest launch part is the 480, and it wont have 512sps...
so there wont even be GTX480 Ultra reviewer editionTM cards?

hmmmm i wonder if some people will actually buy a tesla card for 2500$ to get the additional 16sps and win in some benchmarks, wouldnt surprise me

about gtx480 temperatures... did you guys see the fermi approved thermaltake case at cebit? it has a huge duct for the vgas in it... its really cool if you ask me, literally!
if id use a case id probably use that one!
but it sounds as if this duct is required to run 3 480s next to each other without any plastic melting... thats less cool... literally...
