NVIDIA "Kepler" GeForce GTX 680 official specifications sheet leaked!

The slide leaked from PCOnline.com.cn site and it seems to be the real deal. The specification list reveals already rumored and pretty much confirmed numbers of a single core flagship GeForce GTX 680.

The Nvidia GTX 680 will have a very high GPU clock at a quite impressive 1006MHz.


Specifications and price:

Kepler GK104 will have die size of 294mm^2 and 3.54 billion transistors
CUDA Cores: 1536
Base Clock: 1006MHz
Boost Clock: 1058MHz
Memory Config: 2GB of GDDR5 paired with a 256-bit memory interface and clocked at 6.0Gbps
TDP: 195W
Power Connectors: in line two 6-pin PCI-Express power connectors
Outputs: 2x DL-DVI, HDMI, DisplayPort 1.2
Bus Interface: PCI-Express 3.0 x16 bus interface

Price: MSRP of US $549
Release date of GeForce GTX 680 is set for March 22nd.

GeForce GTX 560 Ti, GTX 570 and GTX 580 are getting price cuts up to $50 (GTX 580 is already available at lower price).

Nvidia GK104 PCB pictured with some unusual power connector design!

First "real" Kepler (GK104) PCB shot from Asian website chiphell! They claim to be a real picture of the reference PCB.

The PCB is green in color and it's obviously an early engineering sample. The final product (branded GeForce GTX680 / GTX670 Ti) will likely have a black-colored one. The estimated length of the card is about 25 cm. On the picture we see the front side of PCB of a total 8 memory chips, which confirms the heavily rumoured 256Bit wide memory interface, with likely 2 GB of GDDR5. But it may be even 512-bit interface if the memory chips are placed also on the back side!
 

On the CAD drawing of NVIDIA's GeForce Kepler 104 (GK104) reference board we see that there are two SLI bridge connectors, giving it 3-way and 4-way SLI support. Two way SLI bridge interface appears only on the flagship graphics cards! It seems that NVIDIA could potentially aim with the GK104 as a high-end product to compete with AMD's flagship card Radeon HD7970! 

Other connectors on the card are dual DVI, one HDMI and one DisplayPort output. The card is loaded with a 5+2 phase power design (5-phase NVVDC configuration).

On the last two pictures we see a strange double-decker power connector. External power supply has a new plug with two 6pin PCI-E + 8pin PCI-E connector!

Entire NVIDIA "Kepler" series GPU Specifications leaked!

 

Nvidia Kepler specs are "finally" out! Lineup has been "fully detailed", with specifications including clock speeds, memory totals and bus bandwidth.

Bumping through the list, specs shows us that reference GTX680 will have just 2GB! But even with 1GB less than HD 7970, Nvidia GTX680 is able to perform 45% faster. Also GTX680 boasts double the amount of stream processors compared to GTX580. We already know that the entire Kepler series will be PCI-E 3.0 compliant and that is manufactured on TSMC’s 28nm technology. For a $100 more than HD 7970 you’ll be getting almost a 45% faster card! GTX680 is priced at $649 and will be released in April 2012.

The GTX 680 will apparently perform 45% better than the HD 7970. Well, this is a bold claim as AMD's new HD 7000 series cards made big performance gains over the past generations already. I’d like to see some TDP ratings as well. 

 Only time will tell!  So i would take this specs with a grain of salt.

NVIDIA Prepares "KEPLER - 28nm" Next Generation “GTX680″

 NVIDIA Prepares 28nm Sample Chips for Next Generation “GTX680″ GPU Codenamed KEPLER



Fudzilla has got some exclusive info on Nvidia’s Next Generation GPU Architecture aka “Kepler”. According to the site, The company has already produced 28nm Samples of its new core.

The samples would be used as Entry Level Cores however come with TSMC’s High Metal gate 28nm process which could also suggest the same chips would be equipped in the rumored “GTX 680″ Graphics Cards which would be a High-End GPU. GF1x9 is the Code name being used for the chips.

The production of the chips wont start before 2H 2011 but demonstrations and architecture details of the Engineering samples would be shown off with in a few months. Global foundaries are expected to get the samples chips as early this Quarter of 2011. AMD is also preparing a revised architecture for their HD7*** Series GPU’s which you can check out here.

Keplar from Nvidia would be twice as fast as the Fermi chips and would also enhance performance per watt due to the smaller die size which would consume lesser power.
