16nm FinFET... It's Time To Shine
We all knew the 16nm FinFET process was going to deliver the goods, and with the second card in NVIDIA's arsenal of Pascal video cards, the GeForce GTX 1070 shines. We have a 150W TDP powered by a single 8-pin PCIe power connector, which is a huge achievement considering the GTX 1080 was already a power efficient card with its 180W TDP.
The GeForce GTX 1070 is capable of everything the GTX 1080 can do, but it uses 30W less power and doesn't have GDDR5X memory at 10GHz. Instead, NVIDIA used GDDR5 and clocked it to the dizzying heights of 8GHz, which is plenty fast enough - something you'll see in our benchmarks shortly.
No X, But That's Fine
I really thought that the GDDR5X on the GeForce GTX 1080 was going to be the standout reason to buy the higher-end card, but it seems like that's not the case. NVIDIA opted for GDDR5 on the GTX 1070, but clocked it up to 8GHz, up from 7GHz on their previous cards. This is quite a large jump, as it's the fastest GDDR5 memory on a card ever.
As you'll see later on in the review, the 8GB of GDDR5 on the GTX 1070 is ample enough when it comes to bandwidth - as it stays toe and toe with its bigger brother.
DisplayPort 1.4 & HDMI 2.0b Allow for 8K 60Hz, and 4K 120Hz
DisplayPort 1.4 and HDMI 2.0b are super exciting, as they'll allow for higher resolution displays, as well as even higher refresh rates. DP1.3/1.4 is capable of powering 4K 120Hz, up from the 4K 60Hz standard right now. Even more so, DP1.3/1.4 will enable 5K @ 60Hz (which right now requires two DP cables), and 8K 60Hz (with two cables).
The GeForce GTX 1070 has 3 x DP connectors, 1 x HDMI 2.0b and a dual-link DVI connector, with it capable of running four displays simultaneously. Not only that, but we have HDR support, as well as video encoding and decoding. Pascal supports HDR video (4K@60 10/12b HECV Decode), HDR record/stream (4K@60 10b HECV Encode), and HDR Interface Support (DP1.4).
