NVIDIA Announces GeForce GTX Titan X
by Ryan Smith on March 4, 2015 1:45 PM EST
During today’s GDC session on Epic’s Unreal Engine, NVIDIA CEO Jen-Hsun Huang dropped in as a special guest to announce NVIDIA’s next high performance video card, the GeForce GTX Titan X.
In order to capitalize on the large audience of the Unreal session while not spoiling too much ahead of NVIDIA’s own event in 2 weeks – the NVIDIA GPU Technology Conference – NVIDIA is playing coy with details on the product, but they have released a handful of details along with a product image.

The GPU underlying GTX Titan X is 8 billion transistors, which similar to the original GTX Titan’s launch means we’re almost certainly looking at Big Maxwell. NVIDIA will be pairing it with 12GB VRAM – indicating a 384-bit memory bus – and it will once again be using NVIDIA’s excellent metal cooler and shroud, originally introduced on the original GTX Titan.
No further details are being provided at this time, and we’re expecting to hear more about it at GTC. Meanwhile Epic’s master engine programmer Tim Sweeney was gifted the first GTX Titan X card, in recognition of NVIDIA and Epic’s long development partnership and the fact that Epic guys are always looking for more powerful video cards to push the envelope on Unreal Engine 4.

If that's the case, then I'll retract my swag. Though I can't say I've run across anything that suggests it will hit 1/4, but a lot of things that suggest Maxwell as a whole is down on FP64 compared to Kepler. That said, if that's truely a limit, then this is not what the Titan was/is/should be, and as a pure gaming card, no matter how great, cannot command that price.huaxshin - Wednesday, March 4, 2015 - link
GK104: 3.54billion Transistors. 1536 cores. 23046875/coreGM204: 5.2billion Transistors. 2048 cores. 25390625/core
GK110: 7.1billion Transistors. 2880 cores. 24652777/core
GM200: 8.0billion Transistors. x cores
80000000000/x = 26600000 (roughly due to higher density with Maxwell like shown with GM204)
80000000000 = 26600000x
x = 80000000000/26600000
GM200 Transistor Count: 3007
Nearest SMM: 23, Rounding up to 24
GM200: 24SMM, 3072 Cores. 384bit, 12GB VRAM
Thats my estimation

While your conclusion of 24 SMMs is likely* correct, the assumptions made to get to that figure are wrong. The core counts you've listed are FP32 cores. There's a WHOLE lot more going on in a GPU that FP32 cores. ROPs, memory controllers, display transmitters, and more are part of the transistor count. GK1xx and GM2xx don't even share the same ratio of FP32 to FP64 cores. Calculating the number of transistors per core from the total figure just isn't right.likely* = So likely that it's almost a certainty.

GK110 is there ;)nunomoreira10 - Wednesday, March 4, 2015 - link
Gm 206: 1024 shadersGm 204: 2048 shaders
Gm 200: 3072 shaders
detecting a small patern lol
but i dont think the shaders per SMM are going to stay the same or the size,
the Gm 206 is a rectangle because it only has one row of SMMs
the Gm 204 is a square because it has 2 rows
the Gm 200 would be too tall, and not a square if it had 3 rows, wich it would make it unoptimal, and maybe even impossible to manufacture given the size.
A square die is almost certain, lets see how they do it.

The number of FP32 cores per SMM in GM200 is almost certainly the same as in GM204. What's up in the air is the number of FP64 cores per SMM. I can't imagine they'd stick with the paltry figure in GM204 and call this thing a Titan, so expect changes there.There's also nothing that says that repeated blocks have to be arranged in a fixed grid. It's just convenient to do so. Look at die shots of GK110. They can pretty much do whatever they damn well please...within reason.

in the GK110 case 3 rows tall was just about perfect for the square die, in this case 2 is too litle and 3 is too much, unless they lay down one row, they ar going to adjust the SMMs tall/wide relationUrizane - Thursday, March 5, 2015 - link
Why 3 x 8 when 4 x 6 is an option? Also, they could do a 5 x 5 grid with the 25th space taken up by ROPs, GPC common hardware, crossbar hardware, whatever else they want.TheRealAnalogkid - Wednesday, March 4, 2015 - link
IIRC, wasn't the GTX 690 the first with the metal cooler and shroud, albeit central fan location?I'm betting this will be $1500- and plenty of game applications with 4k monitors/60+ refresh.

Gonna be another $999 marketing gimmick that nobody actually buys, or regrets 2 months later if they do, when the GTX equivalent comes out?That said, good on ya Nvidia. Keep forcing AMD to compete.
