Of course, these are all results that came from Nvidia so we'll hold our judgement until we see some reviews.Īs noted before, the card is based on Nvidia 28nm GK104 Kepler chip that is around 300mm² in size. The performance of the GTX 680 is somewhere around Radeon HD 7970 as it wins in some games and benchmarks and loses in others. This is a big win for Nvidia as we aren't used to hearing performance per Watt from Nvidia and now it appears that the tide has turned. When combined with 1536 shader units, 2GB of GDDR5 memory clocked at 6GHz and, according to what we heard, a very high GPU clock, it comes as no surprise that Nvidia is claiming higher performance per Watt for its upcoming GTX 680. It looks like our sources were spot on yesterday when we heard that the new GTX 680 will feature two 6-pin PCI-Express connectors and have a TDP of around 200W (190W to be precise). We already wrote that Nvidia planned to hold a GTX 680 related event yesterday, and it is no wonder that we now have a bit more info regarding the card, while Chiphell has provided a much more clear picture of the actual card.

An educated guess would put the cost in line with AMD's flagship card at around the $550 mark, but we'll bring you the full details as and when they emerge. Unfortunately there's no release date for the card yet, and pricing is also unknown. We'll have to wait to see how these numbers translate to performance, but we recently saw a mobile version of the Kepler GPU giving an ultrabook an extreme performance boost, so our hopes for the desktop card are high. The lower power consumption explains the switch to a dual 6-pin PEG connector setup for power. The number of CUDA cores has been upped to 1,536 - a significant increase over previous generations - and 2GB of 256-bit GDDR5 RAM will be included.ĭespite the across-the-board spec bump, the GTX 680 apparently has a TDP of just 195W - far more frugal than the GTX 580 it replaces, which uses 244W.
According to a leaked slide, the GPU will be clocked at 1,006MHz but will be able to temporarily increase its speed to 1,058MHz when necessary, which we assume will work in a similar way to Intel's Turbo Boost technology. The 680 will be Nvidia's first card built using a 28nm process and the company's answer to AMD's Radeon HD 7970. Images and specifications of Nvidia's upcoming GeForce GTX 680 Kepler graphics card have cropped up early on a number of Chinese sites. Well it looks like the specs and and a photo of the GTX 680 is now circling around for people to view! For those of you at work, and unable to browse around everywhere, here you go!
