Introduction:-
The new GeForce GTX 780 marks an evolution in gaming performance—an insanely fast, smooth, and whisper-quiet experience. It’s perfectly tuned to today’s most advanced gaming technologies with GeForce Experience™ for one-click driver and setting optimization, plus NVIDIA® PhysX® and TXAA™ for smooth, sharp graphics. With GTX 780, experience pure performance.
CHIP DESIGNER Nvidia has refreshed its range topping single GPU enthusiast graphics card with the 2,304 core Geforce GTX 780.
Nvidia's Geforce GTX 680 was announced over a year ago and competed against AMD's Radeon HD 7970 and more recently Radeon HD 7970 GHz edition. While AMD has stuck with its Radeon HD 7970, Nvidia has launched a preemptive strike with its Geforce GTX 780, based on the same Kepler architecture as its predecessors but with a bump in memory to 3GB.
With Nvidia sticking to its Kepler architecture for the Geforce GTX 780, the firm isn't promoting Earth shattering performance figures but a steady increase in performance. On the specifications sheet, Nvidia's Geforce GTX 780 looks like a fair refresh, with 2.304 cores clocked at 863MHz that can be boosted to 900MHz.
Nvidia also touts impressive 4TFLOPS single precision floating point performance from those 2,304 cores. However Nvidia's decision to bump onboard memory from 2GB to 3GB of GDDR5 384-bit memory is perhaps the most important upgrade for those that run multi-display setups.
Design and build:-
The GTX 780 is the spitting image of the Titan, and that’s because it uses the same cooler. The length and weight of the card is pretty much identical as well. Like the Titan, the GTX 780 is another stunner in terms of design and build quality. The attention to detail is quite remarkable for a component that’ll never be seen once it’s inside your cabinet. The brushed aluminium topped blower-style fan and the transparent cover for the vapour chamber all add to the premium look of the product. The cooler is completely sealed off, so the fan sucks in cool air from the front and expels it directly outside your chassis.
For connectivity, we have two DVI ports (DVI-D and DVI-I) along with a full-sized DisplayPort and HDMI ports. The GTX 780 also supports SLI so you can shove two of these into your system if you plan on going with a multi-monitor setup. The GTX 780 requires a 6-pin and an 8-pin power connector to work; Nvidia recommends using at least a 600W PSU. The TDP of the card is about 250W with a maximum thermal threshold of 95 degrees Celsius.
Features:-
The new GTX 780 is based on the same GK110 silicon as the Titan. With just 12 SMX units on the GTX 780 (total 15 on Titan), we have 2304 CUDA cores or shader units and 48 ROPs. Compared to the GTX 680, the GTX 780 has about 50 percent more cores. We also have 3GB GDDR5 memory clocked at 6008MHz (effective) running on a wider 384-bit memory bus. Overall, Nvidia claims that the GTX 780 offers up to 34 percent more performance as compared to a GTX 680. We’ll soon find out if it does actually deliver.
Other than the reworked Titan core in the 780, the card will also be launching alongside the new R320 driver suite, which will include a newer version of GeForce Experience (GFE) with new fetaures. This package will soon replace the Nvidia Update utility and will be accessible from the taskbar. New Features in GFE includes Optimal Playable Settings, where depending on your configuration, the software will automatically adjust the settings for the supported game before you launch it. We will also have support for Nvidia SHIELD and ShadowPlay.
The latter is a FRAPS like utility, which keeps recording the last 20 minutes of gameplay. Unlike FRAPS, however, ShadowPlay uses the GPU’s cores for encoding, so there shouldn’t be that big a performance hit. This feature will only work on Kepler GPUs, however, which includes the 700 and the 600 series, scheduled to come out later.
