Next-generation graphics: NVIDIA Pascal GP100 chip reportedly moving on to testing phase

According to a report from German-language website 3DCenter.org, the flagship GPU for NVIDIA’s next-generation Pascal architecture has graduated to the testing phase.

Codenamed GP100, the chip has supposedly been shipped in a limited batch from foundry partner TSMC to NVIDIA for further testing and evaluation. The shipment came to light when the chips tripped speed traps at changeover airports on their way to NVIDIA for testing, which led to 3DCenter getting hold of the shipping manifest.

If the latest reports are to be believed, GP100 will feature up to 17 billion transistors and be based on the 16nm FinFET process at TSMC. In comparison, the current flagship GM200 GeForce GTX Titan X GPU features 8 billion transistors and is based on a 28nm manufacturing process.

GP100 will also supposedly use second-generation High Bandwidth Memory (HBM). AMD’s Radeon R9 Fury X, Fury, and Nano cards use 4GB of first-generation HBM, but Pascal’s second-generation HBM is reported to allow up to 32GB of memory.

The final version of the flagship GP100 GPU could see up to 16GB of HBM, a huge leap over the current 4GB on AMD’s HBM products. As we noted in our review of the Radeon R9 Fury X, there’s nothing stopping manufacturers from going beyond 4GB. Estimates put the potential performance increase anywhere upwards of 50% over the GeForce GTX Titan X.
