With much fanfare, NVIDIA released the specs of the GeForce GTX 1080 in the first week of May but withheld those of the GeForce GTX 1070 to let the GTX 1080 bask in all the limelight. Even early this week, as the embargo for the GTX 1080 ended, NVIDIA did not reveal the specifications of the GTX 1070 and mentioned that it would do so a little before June 10, i.e. when the GTX 1070 will actually hit the shelves. Well, they’ve gone ahead and released the specifications on GeForce.com. Here’s the GTX 1070 compared to the 1080 and a few Maxwell cards.

The GTX 1070 will have 1920 CUDA cores while using the same Pascal GP104 GPU that the GTX 1080 is based off. Since the Pascal architecture puts 128 CUDA cores per Streaming Multiprocessor, we can calculate that the GTX 1070 will feature 15 SMs against the 20 SMs that the GTX 1080 has. When the Maxwell cards came out, the GTX 980 had 16 SMs and the GTX 970 had 13 SMs. This led to a disparity of 18.75 per cent. However, with the GTX 1070 and GTX 1080, that gap widens to 25 per cent. Moreover, the GTX 1080 has GDDR5X memory running at 10 Gbps and the GTX 1070 is using GDDR5 memory running at 8 Gbps. This difference increases the disparity even further, bringing it approximately at around 26-28 per cent. This is a surprising move and would mean that the GTX 1070 and GTX 1080’s price/performance ratio is somewhat similar. With Maxwell, the GTX 970 offered much better price/performance compared to the GTX 980, so it doesn’t seem like we’ll see the same with the GTX 1070.
The other difference is that of the TDP, the GTX 1070 is designed for 150 W while the GTX 1080 is designed to dissipate 180 W. Speaking of the disparity, there’s a 30 W difference against a 20 W difference in the Maxwell flagships. And it still uses a single 8-Pin connector like the GTX 1080 though we might see board partners slapping on more connectors for all the groovy cooler designs and …*sigh* RGB lighting.
GTX 1070 Price
As of now, we’re still awaiting for official Indian pricing so there isn’t much to be said on that front. The Founder’s Edition GTX 1070 will retail at $449 (Rs. 30,291) while board partners will have their cards priced in the vicinity of $379 (Rs. 25,569). Importing these graphics cards will cost somewhere in the vicinity of 6.5K, so you can expect these cards to cost from Rs. 32,000 onwards for the non-Founders Edition SKUs.
UPDATE: 10 June 2016
The NVIDIA GeForce GTX 1070 is officially priced at Rs.40,800 in India.
