Basic introduction
NVIDIA will publicly display the nearly final version of the "Pascal" graphics card for the first time at the GTC 2016 graphics technology conference next month, and it will definitely be a flagship product based on the top core GP100. There is also news that it will be released in June, but The first launch will be the mobile model. The latest news from Taiwan media says that you don’t have to wait too long for the new desktop card. “GeForce GTX 1080” has been confirmed to be launched on May 27 and shipped immediately, but the core is not the top GP100, but the mainstream GP104. That is, it will replace the current GM204 GTX 980
NVIDIA has been promoting that the new generation of graphics cards will introduce HBM2 memory and be ahead of the first AMD to use it. However, that is obviously the treatment of the GP100 core. GP104 will continue to be equipped with GDDR5 or use the upgraded version of GDDR5X, and the capacity is determined to be 8GB. The prefetch width of GDDR5X memory is doubled to 16n, the voltage is also reduced to 1.35V, and the bandwidth can reach 14-16GB/s, which is twice that of the current GDDR5. For HBM2, NVIDIA chose to cooperate with Samsung Electronics, while AMD continued to partner with SK Hynix. Both companies have announced that they will mass-produce HBM2 with a single 4GB capacity in the third quarter, and will also release 8GB by the end of the year. By then, we will see top-level cards equipped with 32GB HBM2. The specific specifications of the GTX 1080 are unknown, but there should be an 8-pin auxiliary power supply, and the output interfaces are DisplayPort × 2, HDMI × 1, and DVI × 1. The first release is still the public version, and the non-public version will have to wait until after July. Of course, the GP104 core is also manufactured using TSMC’s 16nm FinFET process.
