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. 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. This alone will account for a significant boost in performance over that card.The Nvidia GeForce GTX 680 is a DirectX 11 high-end desktop graphics card. On the GTX 670, this card's spiritual predecessor, one of the SMs was disabled, reducing the total number of stream processors to 112, the tesselation units to 7 and the texture units to 112. These are accompanied by four rasterisers, 128 texture untis, 8 tessellation units and 32ROPs. Specifically it sports 1,536 Stream Processors (SPs) split up into four Graphics Processing Clusters (GPCs) and eight Streaming Multiprocessors (SMs). Getting back to the GK104 processor at the heart of the GTX 770, it is as mentioned identical to that of the GTX 680, which debuted the Kepler architecture. In fact, this card is only 20W lower TDP than GTX 780/GTX Titan. With a TDP of 230W, the card is quite a bit more power-hungry than the GTX 680 (195W) and as such requires both a six- and a four-pin PCI-E power input, compared to the 680's twin six-pin connectors. The usual array of outputs are on offer with two dual-link DVI, HDMI and DisplayPort, allowing for surround gaming with three monitors. One potential downside of this fancy cooler is that the card is a bit longer and quite a bit heavier than both the GTX 670 and GTX 680: a concern if you're looking to include it in a Small Form Factor (SFF) or semi-portable build. The cooler is also more effective with its vapour chambers allowing it to be extremely quiet when idle and provide more headroom when under load. As we pointed out in our reviews of those cards, this is one impressive looking cooler with a sleek mixture of aluminium and black plastic, a pointless but rather spiffing clear window above the heatsink fins and an all-important glowing green GeForce logo along its spine. This new card sports the same HSF as the GTX Titan and GTX 780. While the chip at its heart may not have seen huge leaps forward, you'd never guess the GTX 770 was a mere overclocked GTX 680.
Two memory options will be available with either 2GB GDDR5 or 4GB GDDR5. It also benefits from the improved Boost 2.0 advances of the GTX 780, for better granular management of its internal overclocking abilities. Instead the new card sports a modest core overclock from 1,006MHz up to 1,046MHz (1,058MHz to 1,085MHz boost) and a slightly more significant memory overclock from 6GHz to 7GHz. As with the GTX 780, there are no advancements in silicon production that we expect to lead to performance or power-consumption enhancements. Yes, the GTX 770 is essentially a re-badge job.
