Nvidia publishes specifications of GTX 1070 with 1920 cudacores
Just like the GTX 1080, the Nvidia GeForce GTX 1070 will have a GPU with 7.2 billion transistors, but of the 20 streaming multiprocessors, 15 are enabled. This results in a quarter fewer cudacores. The maximum boost speed is slightly lower than with the top model.
Nvidia made little known about the latter during the presentation of the GTX 1080 and 1070 at the beginning of May. Now the manufacturer has revealed the specifications and it appears that the video card has 15 enabled streaming multiprocessors, with 1920 cudacores and a maximum boost speed of 1683MHz. The GTX 1080 has 20 SMS and 2560 cudacores with a boost of 1733MHz, although reviews show that the speed often exceeds 1.8GHz in practice.
It was already known that the GTX 1070 will get 8GB gddr5 memory; the speed is 2GHz. The GTX 1080 has 8GB of gddr5x memory, which is clocked at 1250MHz lower, but because the prefetch buffer is twice as large, the throughput is doubled. The memory bandwidth of the GTX 1070 is 256GB/s, compared to 320GB/s for the GTX 1080. The tdp of the GTX 1070 is slightly lower at 150 watts than the 180 watts of the GTX 1080.
On Tuesday, several websites, including TechPowerUp and Videocardz, already released information, but there was no source or confirmation from Nvidia. According to PC World, Nvidia has confirmed that the information is correct. The published data contains more details about, for example, the rop’s and tmu’s, which Nvidia does not have on its website.
No benchmarks of the GTX 1070 have been published yet. The reviews of the GTX 1080 went online on Tuesday. This shows that the top model is about 30 percent faster than a GTX 980 Ti at stock speed. Given the specs, the GTX 1070 is expected to perform roughly on par with the 980 Ti, but benchmarks should show this. It is not yet known when they will appear. Nvidia itself claims that the GTX 1070 is about 70 percent faster than the GTX 970 in games like Rise of the Tomb Raider and The Witcher 3: Wild Hunt.
The ‘Founders Edition’ of the video card will be on sale from June 10. This is a more expensive variant with reference design from Nvidia. It is not yet known when manufacturers will come up with their own versions. The Founders Edition has a suggested retail price of $449. Custom PCB variants will start at $379. Converted, including VAT, it comes to about 477 and 402 euros. The euro suggested price is probably higher. With the GTX 1080, for example, that is 789 euros compared to 699 dollars.
