Nvidia Pascal GP104 GPU Close Up Shots Reveal More Details
The launch of Nvidia’s consumer grade Pascal graphics cards is only a few weeks away. The US based chip maker is rumored to be preparing three SKUs based on its Pascal GP104 GPU. Built on the 16nm process node, the next gen GP104 SKUs will power the upcoming GeForce GTX 1080, GTX 1080 Ti and GTX 1070.
That being said, the first pictures of the GP104 GPU made it to the web a few weeks back, but now we have got a much closer look at the new Pascal GPU. The latest, relatively better quality shots are leaked by VideoCardz, revealing the GPU is no more in the engineering state but in qualification state (QS) which means we should expect the cards based on this chip to debut pretty soon.
The leaked SKU is a cut-down version of GP104-400, bearing the name of GP104-200-A1 which will supposedly be featured on the GeForce GTX 1070 and GTX 1080. The area of the die is measured at approximately 332mm2 which is smaller than both the GM200 and GM204 GPUs.
Further, assuming the GP104 has the same density of FP32 CUDA cores as GP100 GPU aka the Big Pascal, we can expect the former to feature 2560 CUDA cores in total, as well as 8 billion transistors.
If previous reports is to be believed, GP104-200-A1 based GTX 1070 could feature 20nm GDDR5 memory from Samsung, which uses the 8GB DRAM and rated at 2GHz (8GHz effective) memory. Memory bandwidth of around 256 GB/s is expected on the upcoming card along a 256-bit memory interface.
In comparison, the GTX 1080 could feature 8GB of GDDR5X on a 384-bit memory bus, for a total of 320GB/s of bandwidth.
Nvidia is expected to unveil its Pascal based GTX 1000 series graphics cards at Computex 2016 with product availability in mid-June.
