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.
