nVidia GTX780 Review
Sometimes a review just writes itself. If you've skipped through our graphs and just want to know what we think then firstly, shame on you. Secondly, this is a GTX Titan with one less shader group and half the GDDR5 and a big price cut. Why you're still sitting reading and not rushing to snap one up is beyond us. If we didn't have to let you know what we thought, we'd be on the phone with credit card in hand.
In our introduction we mentioned how the specifications of the GTX780 are much closer to the range-topping Titan than we expected.
The GTX Titan had 2688 CUDA cores whereas there are 2304 on the GTX780. Both of which are a world ahead of the 1536 available with the GTX680. The immense increase from the GTX680 to the GTX Titan was part of the reason we expected the GTX780 to come in with something just under the 2000 mark. To find it's a single SMX beneath the GTX Titan was a big surprise. The second area to be reduced for cost reasons was the frankly whopping 6GB of GDDR5 on the GTX Titan has been trimmed down to a more sensible 3GB on the GTX780. However, again, still 1GB ahead of that available on the GTX680.
All of which would lead you to believe that the performance between the Titan and the GTX780 would grow wider as you piled on more and more anti-aliasing and upped the resolution to saturate the PCI Express 3.0 bandwidth and the cards capabilities. If anything the reverse is true with the GTX780 becoming more impressive the more stress you apply.
You might wonder why we're not, and throughout this review haven't, talked about how the GTX680 compares. Frankly, it doesn't. When the GTX Titan came along we were utterly blown away by it, both in price and performance terms. The GTX780 has been trimmed to enable the price to become at least considerable as a purchase for the average user, and yet the performance remains undiminished. We're talking a negligible amount of frames and benchmark points. Nothing you notice.
Not only is the GTX780 the fastest single GPU around (Titan notwithstanding) but it will give you an improvement in frame rate almost regardless of your current setup. It's outstanding. If the battle between the HD7970 and GTX680 was close, then this is a Monty Python sized foot crushing all beneath it and making them instantly seem old hat and out of date. There aren't many products that appear that make us almost want to applaud it, but the nVidia GTX780 is one such item of hardware and, even at this price, unquestionably worthy of our OC3D Gold Award. We want one. No scrub that, we want two. Brilliant.
