NVIDIA GT300 ''Fermi'' Detailed

NVIDIA's upcoming flagship graphics processor is going by a lot of codenames. While some call it the GF100, others GT300 (based on the present nomenclature), what is certain that the NVIDIA has given the architecture an internal name of "Fermi", after the Italian physicist Enrico Fermi, the inventor of the nuclear reactor. It doesn't come as a surprise, that the codename of the board itself is going to be called "reactor", according to some sources.

Based on information gathered so far about GT300/Fermi, here's what's packed into it:
  • Transistor count of over 3 billion
  • Built on the 40 nm TSMC process
  • 512 shader processors (which NVIDIA may refer to as "CUDA cores")
  • 32 cores per core cluster
  • 384-bit GDDR5 memory interface
  • 1 MB L1 cache memory, 768 KB L2 unified cache memory
  • Up to 6 GB of total memory, 1.5 GB can be expected for the consumer graphics variant
  • Half Speed IEEE 754 Double Precision floating point
  • Native support for execution of C (CUDA), C++, Fortran, support for DirectCompute 11, DirectX 11, OpenGL 3.1, and OpenCL
Update: Here's an image added from the ongoing public webcast of the GPU Technology Conference, of a graphics card based on the Fermi architecture.

naram-sinBtw, it could all be a piece of... hype to try and halt a couple of percentages of extreme enthusiasts in buying of 58xx and motivate them in waiting for GF100/GT300/Fermi/Reactor or whatever...:laugh:
Totally. Unless they are made of money, the smart move is to wait for nvidia's offering to the graphics gods, see how the prices react, then make your choice. Gives you more time to save too.

looks promising. now if they could just release it on my birthday and send me a few as a gift i'd be 5x as excited.

it seems they skipped a dualcore gpu and went straight to 32cores haha

Is there anybody even doubting that Nvidia's next chip is going to be fast? :laugh:

It seems Fermi will be demonstrated today at 1:00 PM (Pacific time) / 10:00 PM CEST at the footnote of GTC.

I hope they are faster than the 58## series by the same order of magnitude that the GT200 were faster than the 48## series. And that the prices are similar too. It was happy days for the consumer.

that is so true...as for those worrying about ATI, i do believe that they have about a $50 price drop for the 5870 and about $20-$30 drop for the 5850. ATI definitely has NVIDIA where they want them when it comes to pricing as we all know that the GT300/Fermi will be more costly than a 5870 while probably only adding anywhere between 7-15% in performance. ATI is better positioned to fight a price war...

just for fun
plus there's 2 rumors floating around...1-the rumored hemlock being priced at $500 suggest its 2 5850s and not 2 5870s...and 2-not so much a rumor but more of a hypothesis... the 5890.

True -- while I'll admit I'm currently an ATI fan, I've been quite happy with the way things have been during the GTX 200 / HD 4800 days. Everything seems pretty balanced, cost wise and performance wise between both brands. :D

...as long as one stays away from those "TWIMTBP" games. :laugh:

I'm sure I read somewhere that they are lining up both a 5850X2 & 5870X2. If it is true hopefully the 5850X2 will be properly supported and not just a Sapphire plaything.

3 billion transistors? basicly its alot bigger than Cypress, so it will cost more to make, and will be expensive :O
its RV770 vs G200 all over again :P

Well, I guess that would be an MO of reasonable people. Not enthusiasts. :) But, instead of being reasonable, i went enthusiastically with HD4850 and had to wait for a decent aftermarket cooler to be able and play on it. I guess I'll wait this time for some non-reference variant of HD58xx. Or maybe even Reactor, who knows?! But HD4850 can still kick some punches. :)

Btw, it seams to me that it is going to prove useful for our budgets to wait, as you said, because we are experiencing accelerated shortening of time between two generations of GPU architecture. This seams to go for CPUs as well. Of course, not in cases of re-branding of old GPUs as new mainstream and lower-mainstream options. :)

If this card is much superior to the 2GB 5870 or 5890 for the money I will try out the green camp, and they need to clean up their act.

but dont forget, you have to PAY 2 times more for it, remember GT200 cards when they were released?
btw ATI can make 2 times more chips per waffel compared to NVIDIA :P

they need to skip the 384-bit bus bologna crap and give us 512-bit on every high end card from now on. We would be willing to pay the extra $25 or so dollars that it would cost.... Gimme a break

Thier margin means nothing to me, and everybody stop with the bus width, DDR5 allows TWICE the bandwidth per pin compared to DDR3, so a 384 is like a 768.


I just want to run games like GTA4 and newer ones at native res with eye candy to have a immirsive experiance, and unlike what a diehard blowhard NV camp man said yesterday, you want that to get into the game, otherwise he can have a FX card and play on that.

you're fallen from bed maybe...384 bit on ddr5 is more than enough

No, but every bit of info points a greater difference than that on GT200 vs RV770, while the production costs are lower than GT200. That means that heavy competition is inminent.

think i will wait myself... looking to sell my 2 4850s with the scythe musashi coolers on both and or one of my 4850s and my 8800 gt... i need the ati integrated hd sound.

i need to upgrade my q6600 to the i860 msi p55 or equivalent and my current top dog p2 955 with a 5870...so the waiting game for the best bang for my money is the only option really.

Likely this would be priced similar to the 58xx series, hopefully its cheaper and performs better in all scenarios.

Finally something to talk about other than Batman...
This thing will definetly be faster than the 5800 (except for the 5800x2,if something like this really comes out),but i'm still waiting for the actual release to confirm it.After all,didn't a early "bench" of the 5870 said it would be up to 95% faster than the gtx295????

Yeah,right...

you guys and your misquotes about the 5870 being 95% faster than the gtx295...u guys gotta really be ignorant...relatively speaking why would a company do that when they can milk us for our money while squeezing out a marginal percentage improvement bi annually. Not trying to being disrespectful but come on use your head...we knew where the performance was gonna be and for a single card to cost less than a dual card and performs just as good, sometimes better sometimes worst...then that is just awesome for everyone...

I remember when the the gtx285 was what $549..shit the 5850 can beat it for just about half that price...better yet look at the 8800 ultras price point...these new cards thrash that damn card easy and cost way way less. another example i remember when the radeon 9800xtx came out i was just looking to build a pc at that time and i remember seeing $500+ on newegg
