GeForce GTX 1070
The GeForce GTX 1070 is back with GPU GP104, but in a cut-down form. The crystal is manufactured using the 16-nm FinFET process technology, the number of transistors is the same 7,2 billion, even if not all of them are used. The variant GPU GP104 in the GeForce GTX 1070 graphics card has three Graphics Processing Clusters active instead of four. Each GPC contains five streaming multiprocessors, and they, in turn, contain two SM blocks with 64 stream processors.
As a result, the GeForce GTX 1070 has 1.920 stream processors (3x5x2x64 = 1.920). Accordingly, the number of texture units has decreased from 160 to 120. The memory interface still consists of eight 32-bit controllers, the width is 256 bits. Therefore, the number of raster operation pipelines has not changed, remaining 64. NVIDIA specifies the thermal package of the video card as 150 W. Unlike the GeForce GTX 970, NVIDIA did not resort to tricks with the GeForce GTX 1070, limiting the size of the cache or register block. The problem with the cut-down memory controller is also a thing of the past.
NVIDIA has changed not only the number of stream processors and other components of the architecture, but also the frequency compared to the GeForce GTX 1080. The base frequency is 1.506 MHz (GeForce GTX 1080: 1.607 MHz), in boost mode GPU Boost frequency increases to at least 1.683 MHz (GeForce GTX 1080: 1.733 MHz). Instead of GDDR5X, NVIDIA used classic GDDR1070 memory for GeForce GTX 5. But it is installed in a very fast version at 2.000 MHz. Thanks to the 256-bit memory bus, GeForce GTX 1070 provides a memory bandwidth of 256 GB/s (GeForce GTX 1080 - 320 GB/s).

Movement GPU Boost is very temperature dependent GPU – especially for NVIDIA reference graphics cards, which are designed to operate in a certain temperature range. Here, the Power Limit power consumption bar does not have such a strong effect. For the GeForce GTX 1070 Founders Edition, we got a temperature of GPU 82-83 °C at full load. That is, the video card was running into a temperature limit. Accordingly, the Boost frequency did not reach the theoretical maximum of 1.886 MHz, remaining in the range of 1.722-1.785 MHz.
