Nvidia Corp.’s first generation Kepler GPU should emerge in March 2012, according to reports.

The GK107, first of the Nvidia Kepler series, a budget card aimed at a mainstream audience, will purportedly feature a 128-bit memory interface, GDDR5 memory and support PCI-Express 2.0, according to a timeline being touted by Japanese gaming site 4Gamer.net.

The first Kepler cards, successors to Nvidia’s Fermi architecture and based on TSMC’s 28nm process, were initially expected to emerge in late 2011 but production has been pushed back to early Q2 of 2012. First silicon is apparently still on track for this year’s end.

Kepler GPUs will purportedly triple the dual-precision floating point performance of Fermi.

So far, the only motherboards that support PCIe 3.0 are for Intel processors. . .

. . . is this the manufacturers doing Intel first. . . or some compatibility issue with AMD?

NVIDIA Launches First GeForce GPUs Based on Next-Generation Kepler Architecture: GeForce GTX 680 for PC Gamers Is Fastest, Most Efficient GPU Ever Built; GeForce GT 640M for Notebooks Puts the Ultra in Ultrabooks


NVIDIA today launched the first GPUs based on its next-generation Kepler™ graphics architecture, which deliver dramatic gaming performance and exceptional levels of power efficiency.

. . . the GeForce GTX 680 GPU is more than 300 percent faster in DirectX 11 tessellation performance(1) and up to 43 percent faster in cutting-edge games such as Elder Scrolls V: Skyrim(2), yet consumes 28 percent less power(3). It also provides twice the performance per watt of the GeForce GTX 580, the flagship Fermi-based processor that it replaces.

Setting the standard for future enthusiast-class GPUs, the GeForce GTX 680 is built on an array of new technologies, including:


  • A new streaming multiprocessor block, known as SMX, that delivers twice the performance per watt of previous-generation products

  • Special board components, including acoustic dampeners, high-efficiency heat pipes and custom fins, that create a quiet gaming experience

  • NVIDIA GPU Boost technology, which dynamically adjusts GPU speeds to maximize gaming performance

  • New FXAA and TXAA antialiasing and Adaptive VSync technologies to enrich visual quality without compromising gaming performance

  • Support for up to four separate displays -- three of them in 3D -- off a single card for a massive 3D gaming experience

  • Manufactured on TSMC's new 28-nm process, with support for PCI-E Gen 3 and DX11.1

The Kepler GPU used in the GeForce GTX 680 graphics card will have 1,536 CUDA cores, which will run at 1006MHz and will have a turbo boost speed of 1058MHz. This card has 2GB of GDDR5 graphics memory with a 256-bit path to memory running at 6Gb/sec. The card will have two 6-pin power connectors and will have two DVI ports and one HDMI port, and most significantly, will slide into PCI-Express 3.0 peripheral slots coming with the Ivy Bridge family of Core processors from Intel.

The new Kepler GPU puts 192 cores into a streaming multiprocessor extreme with a slightly modified CUDA core, according to Gupta. Eight of these SMX units are on the GPU for a total of 1,536 cores. For whatever reason, Nvidia is not releasing any single-precision or double-precision floating point performance figures yet on the Kepler GPUs, but says that the new SMX module offers twice the performance per watt of the prior Fermi SM unit, and because a card only burns 195 watts, it offers much better performance per watt.

For the gamers out there, it might take three of the GeForce GTX 580 graphics cards, which burned 732 watts, to play the Samaratin video game. But now, Nvidia is claiming that you can get the same performance with only one GeForce GTX 680 video card, and this will only burn 195 watts. No word on what the pricing will be, but the GTX 680 will almost certainly cost more than a single GTX 580 – particularly with the 28 nanometer wafers coming out of TSMC being in short supply.

Second Wave of NVIDIA GeForce GTX 600 Products Due For May


NVIDIA's GeForce GTX 680 literally kicked the door open as it made its entry. We're learning of NVIDIA's plans to milk the GK104 chip by carving out two more SKUs: the GeForce GTX 670 Ti, and GTX 670. These two SKUs will let NVIDIA capture price points deep within the $400-499 and $300-399 ranges, to compete with AMD's Radeon HD 7950 and Radeon HD 7870. These two SKUs will be released in May. Around the May-June time-range, NVIDIA could also introduce the GTX 690, which we're hearing is a dual-GK104 graphics card that's designed to compete with Radeon HD 7990, which launches in April.

Also in May, NVIDIA will launch desktop discrete graphics card SKUs based on the GK107 chip, which makes up its GeForce GT 650M/640M mobile graphics SKUs. Following this, some time in Summer, NVIDIA will release a new chip, the GK106, which will make up the GeForce GTX 660, which will be out to compete with Radeon HD 7850, and HD 7700 series. It looks like NVIDIA is waiting on current inventories of GF114-based SKUs to get digested, including those of the recently-launched GeForce GTX 560 SE, and is hence in no hurry to launch a new GPU to capture the sub-$250 price-points.

Nvidia Kepler GPUs - back to games, away from compute?


Nvidia's first Kepler generation GPU, the GK104-based GeForce GTX 680, is finally out officially. The benchmarks show high game performance, but is - compared to the old 'Fermi' at least - GPU compute performance pushed aside here?

Nvidia is positioning the GTX680 squarely against the HD7970 now, and that's a big difference - HD7970 has waaay faster single precision FP, and many times faster DP FP, thanks to keeping the DP FP rate at 1/4 of SP FP, basically not crippling it to force users into plonking thousands of bucks for an otherwise similar 'pro' card.

GeForce GTX 680: A Marriage of Speed and Extreme Efficiency


The GeForce GTX 680 GPU brings impressive performance and extreme efficiency to the desktop gaming market, delivering a quiet, smooth, extremely fast experience.

Compared with the closest competitive product, the GeForce GTX 680 GPU is more than 300 percent faster in DirectX 11 tessellation performance(1) and up to 43 percent faster in cutting-edge games such as Elder Scrolls V: Skyrim, yet consumes 28 percent less power(3). It also provides twice the performance per watt of the GeForce GTX 580, the flagship Fermi-based processor that it replaces.

Setting the standard for future enthusiast-class GPUs, the GeForce GTX 680 is built on an array of new technologies, including:

  • A new streaming multiprocessor block, known as SMX, that delivers twice the performance per watt of previous-generation products
  • Special board components, including acoustic dampeners, high-efficiency heat pipes and custom fins, that create a quiet gaming experience

  • New FXAA and TXAA antialiasing and Adaptive VSync technologies to enrich visual quality without compromising gaming performance
  • Support for up to four separate displays -- three of them in 3D -- off a single card for a massive 3D gaming experience
  • Manufactured on TSMC's new 28-nm process, with support for PCI-E Gen 3 and DX11.1


Kelt Reeves, president of Falcon Northwest, a leading producer of high-end gaming systems, said:

The GTX 680 lays down what should be whiplash-inducing speed at the sound of a whisper. Even at full throttle, it doesn't heat up. In the immortal words of Obi-Wan describing a lightsaber, it's 'an elegant weapon for a more civilized age.

GTX 685 4GB KEPLER GK 110 Monster - August 2012 First-Spec vs GTX 680 2 GB and 7970 3 GB


New GK110 chip may have up to 550mm2 of die size. This would be 87% more than actual GK104. Some say this is too much, and NVIDIA will not release gpu that large, because cost production of such gpus is significantly higher. But latest rumors suggest that it may be somewhere in those dimensions. Bigger die allows engineers to put more SMX's on new gpu. It is said that GK110 may have up to 2304 CUDA cores. NVIDIA is already preparing their GeForce GTX 690, a dual-GK104 card, which will have 3072 CUDA cores. This would put AMD in very bad position. AMD is already preparing factory overclocked Radeon HD 7970 as a response to GTX 680 performance. There are also plans for Radeon HD 7990, which will put AMD on the top position of performance race for a moment. NVIDIA will release their dual-gpu GTX 690 card right after that, which will replace a winner once more.

The GTX 690 is powered by a total of 3,072 NVIDIA CUDA® cores, all working to deliver awesome gaming performance for ultimate gaming setups. Designed for the discriminating gamer and ultra-high-resolution, multimonitor NVIDIA Surround™ configurations, the GTX 690 delivers close to double the frame rates of the closest single GPU product, the GTX 680. Plus, it is more power efficient and quieter when compared to systems equipped with two GTX 680 cards running in NVIDIA SLI® configuration.

"The GTX 690 is truly a work of art -- gorgeous on the outside with amazing performance on the inside," said Brian Kelleher, senior vice president of GPU engineering at NVIDIA. "Gamers will love playing on multiple screens at high resolutions with all the eye candy turned on. And they'll relish showing their friends how beautiful the cards look inside their systems."

The GTX 690 graphics card is designed using GeForce GPUs based on NVIDIA's 28-nanometer Kepler architecture, following the introduction late last month of the GTX 680.
