I'd crown the new GTX 1070 as the new God-Emperor of gaming GPUs, except that this card really the baby sister to the GTX 1080, which offers even better performance. On the other hand, eVGA's GeForce GTX 1070 SC costs $439 -- $10 shy of Nvidia's own "Founder's Edition" -- while delivering clock frequencies roughly 6% higher than the reference clocks. Audible noise levels seem slightly lower as well.
While I ran the usual set of benchmarks on the card, I've been living with with eVGA's GTX 1070 in my main system for nearly a week, running games on my 3440 x 1440 pixel Dell U3415w display. Subjectively, I could tell little difference between this card and the GTX 1080 Founder's Edition I'd been running. I did have to dial back ambient occlusion a bit in Tom Clancy's The Division. Doom, Mirror's Edge Catalyst, XCOM2, and several VR titles on the HTC Vive all seemed to run with excellent frame rates on gorgeously high settings.
So What's a GTX 1070?
Take a part that starts out life as a potential GTX 1080 GPU, disable one graphics processing cluster, and voila! You now have a GTX 1070 chip. Each graphics processing cluster consists of 5 graphics compute cores (which Nivdia dubs "streaming multiprocessors" or SMs for short). Let's break down the differences with the reference design -- er, Founder's Edition –in the table below.
The GTX 1070 uses less exotic GDDR5 memory, clocking said memory at a pretty serious 4GHz – faster than the 7gbps memory used in previous generations. So the GTX 1070 includes fewer shader cores, slightly lower clock frequencies, slower memory, and should cost roughly $300 less.
Nvidia suggests some 3rd party cards will be priced as low as $379, though all currently available 1070 cards seem to cost more than $400. Availability remains tight, but a cards from MSI and Gigabyte seem to be available. Supply will no doubt catch up with demand after several months.
