Default GK110 Packs 2880 CUDA Cores, 384-bit Memory Interface: Die-Shot

With its competition checked thanks to good performance by its GK104 silicon, NVIDIA was bold enough to release die-shots of its GK110 silicon, which made its market entry as the Tesla K20 GPU-compute accelerator. This opened flood-gates of speculation surrounding minute details of the new chip, from various sources. We found one of these most plausible, by Beyond3D community member "fellix". The source of the image appears to have charted out component layout of the chip by some pattern recognition and educated guesswork.

It identifies the the 7.1 billion transistor GK110 silicon to have 15 streaming multiprocessors (SMX). A little earlier this week, sources close to NVIDIA confirmed the SMX count to TechPowerUp. NVIDIA revealed that the chip will retain the SMX design of GK104, in which each of these holds 192 CUDA cores. Going by that, GK110 has a total of 2880 cores. Blocks of SMX units surround a centrally-located command processor, along with six setup pipelines, and a portion holding the ROPs and memory controllers. There are a total of six GDDR5 PHYs, which could amount to a 384-bit wide memory interface. The chip talks to the rest of the system over PCI-Express 3.0.
