NVIDIA GK106 GPU Detailed

Following the launch of a couple of more GK104-based SKUs, namely GeForce GTX 670 Ti, and GeForce GTX 670, some time in May; NVIDIA will launch its third (after GK104 and GK107) Kepler architecture-based silicon, codenamed GK106. GK106 will make up sub-$200 SKUs, and succeeds the GF116, on which SKUs such as the GeForce GTX 550 Ti, are based. The GK106 will make up at least one known desktop SKU, called GeForce GTX 660.

Its specifications are listed below.

New GK104 SKU Details Surface

We know from a late-March article that NVIDIA is working on two new SKUs based on its GK104 silicon, for launch in May. With the Kepler architecture, particularly with the design of the new-generation Streaming Multiprocessors (SMX), NVIDIA substantially increased CUDA core density. Each SMX holds 192 CUDA cores, and as with the previous-generation Fermi architecture, the SMX count is the only thing NVIDIA can tinker with, to control CUDA core count in new GPUs. GeForce GTX 680's little brother, hence will have 7 out of 8 SMX units enabled, and end up with a CUDA core count of 1344. This leaves easier to configure parameters such as clock speeds, for NVIDIA to design the perfect SKU to capture a price-point. NVIDIA is targeting the sub-$399 market, while somehow maintaining competitiveness with Radeon HD 7950.



Specifications of the new SKU follow.

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. Besides the dual-GPU Radeon HD 7990, there's nothing new in the works, at the red camp that we know of.Source: 3DCenter.org

Did NVIDIA Originally Intend to Call GTX 680 as GTX 670 Ti?

Although it doesn't matter anymore, there are several bits of evidence supporting the theory that NVIDIA originally intended for its GK104-based performance graphics card to be named "GeForce GTX 670 Ti", before deciding to go with "GeForce GTX 680" towards the end. With the advent of 2012, we've had our industry sources refer to the part as "GTX 670 Ti". The very first picture of the GeForce GTX 680 disclosed to the public, early this month, revealed a slightly old qualification sample, which had one thing different from the card we have with us today: the model name "GTX 670 Ti" was etched onto the cooler shroud, our industry sources disclosed pictures of early samples having 6+8 pin power connectors.

Next up, while NVIDIA did re-christian GTX 670 Ti to GTX 680, it was rather sloppy at it. The first picture below shows the contents of the Boardshots (stylized) folder in NVIDIA's "special place" for the media. It contains all the assets NVIDIA allows the press, retailers, and other partners to use. Assets are distributed in various formats, the TIFF is a standard image-format used by print-media, for its high dot-pitch. Apart from a heavy payload, the TIFF image file allows tags, that can be read by Windows Explorer, these tags help people at the archives. The tags for images in TIFF format, of the GTX 680 distributed to its partners in the media and industry contain the tag "GTX 670 Ti".

GK104 Graphics Card Pictured?

Could this be the very first picture of NVIDIA's GeForce Kepler 104-based graphics card? This Mr. Blurrycam shot has been doing rounds in Chinese forums. While it may not seem convincing at first glance, several features of the card in the picture seem to match the layout of the GK104 reference PCB which was pictured, earlier. To begin with, on the top-right corner you can train your eyes to a deep cutout, for the unusual piggy-backed 6+6 pin PCIe power connectors. The rear panel bracket is a 100% match (in layout and design of exhaust vents), of the one with the true-color image of the GK104 PCB. The only feature that clouds the plausibility of this picture is "GeForce GTX 670 Ti" being etched onto the cooler's shroud. We're hearing more voices refer to the top GK104 part as "GeForce GTX 680" than "GTX 670 Ti". We're also hearing that NVIDIA will adopt a new GeForce logo, so that glaring "GEFORCE" badge on the top of the card looks plausible.

GK104-Based Products Arriving March 23

Expreview cited sources in the AIC (add-in card) vendors in pinning the launch of GeForce Kepler 104 (GK104) based products to March 23. The products launched are expected to be NVIDIA's first in its next-generation. Some label the top part based on GK104 as "GeForce GTX 670 Ti", while others call it "GeForce GTX 680". A March 23 launch explains reports of hectic activity in the green camp starting this week. NVIDIA typically enters NDAs with its partners over a wide time range, probably this one extends to April (since the launch is now reported to be towards late-March), which led some to believe Kepler was "delayed" to April. NVIDIA recently posted on its Facebook wall that people will be rewarded for their patience with an "unbeatable" product.

GK104 Board Draws Power From 6+8 Pin Connectors, 3+2 VDD Phase Power Supply

The top desktop graphics card based on the NVIDIA GeForce Kepler 104 (GK104) ASIC, which has come to be known as GeForce GTX 670 Ti, is reported to use a 5 NVVDD phase power supply (VRM) design that draws power from 6-pin and 8-pin power connectors. The card will hence have 300W of power at its disposal. NVVDD phase 1 and 3 will be wired to the 6-pin connector; phase 2, 4, and 5 to the 8-pin connector. NVVDD phases 2, 4, and 5 feed power to the GPU, while phases 1 and 3 power the GDDR5 memory and other components on the board.
