Those can be used to power three-monitor gaming off just one GTX 680, including 3D Vision Surround support, plus the new card can support a fourth "companion" display for things like chat, email, or cheat sheets alongside the others.Īlongside its new flagship GPU, Nvidia is also introducing a pair of new antialiasing modes. On the stock card configuration, you'll find two dual-link DVI ports, one HDMI output, and one DisplayPort connection. Nvidia has reengineered its CUDA processing cores to make them significantly smaller and now counts 1,536 inside its latest graphics chip, which is composed of 3.54 billion transistors, almost 800 million fewer than the HD 7970. That makes for total memory bandwidith of over 192GBps. Other salient specs on the GTX 680 include 32 ROP units, 128 texture units, and 2GB of GDDR5 VRAM running at a screaming 6GHz effective data rate over a 256-bit memory interface. Clock speed adjustments will happen in 13MHz increments every hundred milliseconds, meaning that you'll end up with different clock speeds for different frames inside your game.

Unlike its nemesis, the AMD Radeon HD 7970, Nvidia's new card doesn't require any application-specific software profiles for power management it's all done using hardware monitors, which track power, temperature, and utilization and react almost instantaneously. The reference card comes with two 6-pin auxiliary power connectors, but the more extreme variants will probably be equipped with 8-pin power jacks to help you max out performance.
Nvidia expects its board-making partners to really go to town and overclock - which in this case means raising the operational range higher - the GTX 680 right out of the gate, while advanced tweaking software will be provided to let you make similar changes on the fly as well. Of course, you can also break out of that range, with the card downclocking itself as low as 324MHz when idling and easily reaching stable speeds in excess of 1,100MHz on the upside. The GeForce GTX 680 has a 1,006MHz base clock and a 1,058MHz boost clock and will dynamically alternate between those values depending on load and power consumption. That power figure is important for another reason: Nvidia no longer has a static clock speed for its graphics card. Billed as the most efficient GPU ever put together, the GTX 680 has a very reasonable power envelope of just 195W, breaking with the tradition of every new high-end graphics card requiring more power than the previous generation. Nvidia's long-awaited move to 28nm technology is finally upon us today with the launch of the GeForce GTX 680.
