First, lets look at that Kepler architecture in a bit more detail. Awesome performance, lower power consumption compared to the 580 Win.Enjoy. With even the lowest core clock speed a 30 per cent increase over that of the GTX 580 1.5GB and the net through-put improvement from the new approach to stream processors, there’s clearly a great deal of performance potential here. SYSTEM SETTING:Intel i7 2600K OC 4.5 GHzG SKILL 8 GB DDR3ASUS SABERTOOTH P67680 is finally released. We’ll explain it in greater detail later, but the technology, similar in concept to Intel’s Turbo Boost, results in a GPU that runs at a minimum clock speed of 1,006MHz, with the potential for a stock card to be boosted up to 1,110MHz under the right graphical loads. The result is that the GTX 680 2GB’s 192.26GB/sec of memory bandwidth is slightly less than the GTX 580 1.5GB’s 192.4GB/sec, but some way behind the HD 7970 3GB’s 264GB/sec.ĭespite a small step backward when it comes to effective memory bandwidth, the card’s core clock speed sees a significant new technology in the form of GPU Boost. The memory interface is actually a reduction from the GTX 580 1.5GB though, which, like the HD 7970 3GB, boasts a 384-bit interface. This means that despite tripling the steam processor count, the GTX 680 2GB’s stream processors run 35 per cent slower than those of the GTX 580 1.5GB.Įlsewhere, the GTX 680 2GB offers a 256-bit memory interface, with its GDDR5 running at a blistering 1.5GHz (6GHz effective). The result is a stream processor count of 1,536, triple that of the GTX 580 1.5GB, but with a unified clock speed. Kepler’s design retains some elements of the Fermi architecture, whilst significantly updating parts such as the SM design. In comparison, AMD’s Tahiti XT is much larger, cramming 4.3 billion transistors into a 365mm die. That is no joke since the GTX 680 is a very nice card and capable of running most games flat out at highest settings, so with that we know the GTX 780 has some serious. It’s a 3.54 billion transistor chip, with a die size of 294mm² in comparison to the GTX 580 1.5GB’s GF110 GPU, that has 18 per cent more transistors in a 40 per cent smaller die. As you can see by the chart supplied from Nvidia the GTX 780 is 70 faster than the GTX 580 which many gamers still employ and even a stated 42 over the existing GTX 680. The 28nm Kepler GPU at the heart of the GTX 680 2GB has been dubbed GK104 by Nvidia. There’s a lot of new technology, design choices and features to cover, so we’ll try and hit the basics on this page, before going into (a lot) more detail separately. Nvidia is calling the Geforce GTX 680 2GB the fastest, most efficient GPU ever built bold claims considering the substantial increases on both fronts exhibited by AMD’s 7-series graphics cards.
Can Nvidia banish the Fermi-flavoured demons of 2010 and deliver a GPU to be proud of? Let’s find out.Ĭlick to enlarge - Will the GTX 680 2GB be your next graphics card upgrade? Today sees the first answering shot from Nvidia in the battle for 28nm supremacy, with the flagship GTX 680 2GB taking aim at AMD’s high-end.
#Nvidia gtx 680 benchmarks series#
The HD 7900 series of graphics cards and their 28nm Tahiti GPUs have been on sale for close to three months, with AMD filling out the rest of its range in the meantime to greater (HD 7800 series) and lesser (HD 7700 series) success. Fast forward to 2012 and we again find Nvidia trailing AMD. Shipping six months after AMD had debuted its DX11 GPUs based on the very successful Evergreen architecture, Nvidia was left playing catch up with a card that failed to impress. Two years ago, almost to the day, Nvidia released its first DX11 GPU based on the Fermi architecture, the GTX 480 1.5GB. The power consumption of the GTX 680 desktop card is rated at 195 Watt TDP and therefore two 6-pin power connectors are needed to power the card.It’s funny how history tends to repeat itself. In some cases, even higher resolutions or additional AA/AF are possible.

Demanding games like Metro: Last Light can be played fluently in 1080p and maximum detail settings. Therefore, even the fastest mobile GPUs like the GeForce GTX 780M are outperformed by more than 30 percent. The similar named mobile GeForce GTX 680M is also based on the GK104 chip, but offers only 1344 shader as the desktop GTX 670 and a low clock rate of 720 MHz.ĭepending on game and settings, the performance of the GTX 680 is similar to a Radeon R9 280X. The core clock can be boosted up to 1058 MHz (from 1006 base clock) and the memory is clocked at 3004 MHz (GDDR5). It is based on the GK104 chip and manufactured in 28 nm at TSMC. The Nvidia GeForce GTX 680 is a DirectX 11 high-end desktop graphics card.
