Nvidia GP106 GPU Detailed – 200mm2 Die Size, 4.4B Transistors, & 1280 CUDA cores
Last week, Nvidia announced the GeForce GTX 1060, their new mid-range graphics card based on the latest Pascal architecture. The launch of the card was actually brought forward card to rival AMD’s new Polaris based budget king, the Radeon RX 480. Nvidia claims that the GTX 1060 is powerful enough to deliver performance on par or greater than a GeForce GTX 980, and that is at half the price of 980’s launch MSRP.
Nvidia GeForce GTX 1060 is based on the GP106 GPU which is essentially a cut-down version of the GP104 chip found inside the other two Pascal cards, the GeForce GTX 1080 and GTX 1070. If new leaks are to be believed, the GTX 1060 features a full fat version of the GP106, called the NVIDIA GP106-400-A1 GPU.
The chip has a die size of 200mm2 which makes it 57% smaller than the GP104 GPU and 14% smaller than the predecessor GM206 GPU.
Featuring a total of 4.4 billion transistors, the GP106-400-A1 GPU block consists of a pair of 2 GPC (Graphics Processing Clusters), each of which houses five SM (Streaming Multiprocessor) units. Each SM consists of 128 CUDA cores which means the GP106 has a full core count of 1280 CUDA cores.
In addition, each SM has 8 TMUs (Texture Mapping Units), 256 KB of register file capacity, a 96 KB shared memory unit and 48 KB of total L1 cache storage. This makes a total of 80 TMUs paired with 48 ROPs (Raster Operating Units). The block diagram further reveals that the GP106 GPU packs six 32-bit memory controllers which give us a 192-bit bus interface.
The GeForce GTX 1060 has the highest boost clock speeds of 1.7 GHz which is easily overclocked to 2 GHz thanks to the latest 16nm FinFET process node. The chip delivers a pixel fill rate of 72.3 GPixel/s while the texture fill rate is 159.6 GTexel/s.
In terms of the memory configuration, the GTX 1060 comes with 6GB of GDDR5 memory which is clocked at 8 GHz. Nvidia didn’t mention any 3GB version of the card that was much talked about in previous rumors however, reports are that the 3GB models could debut later with a cut-down version of the GP106 GPU.
The graphics card features a TDP of just 120W and power is provided through a single 6-pin connector. The GTX 1060 features the reference Pascal display configuration of three Display Port 1.4, single HDMI 2.0b and also a single DVI port. Further, the card comes with no SLI fingers which means there won’t be any multi-GPU support on GP106 based GPUs.
Nvidia GeForce GTX 1060 6GB is set to launch on July 19 for a price of $249 for custom cards and $299 for the Founders Edition.
