Let me quote you something from NVIDIA a few months ago:
Nintendo Switch is powered by the performance of the custom Tegra processor.
Tech Insights have determined that the processor is a Nvidia Tegra T210, a stock Tegra X1 processor – not a custom Tegra processor, and a Maxwell-based GM208 GPU.
The T210 CPU features 4 Cortex A57 and 4 Cortex A53 processor cores and the GPU is a GM20B Maxwell core.
Is this a big issue? No, not really. Everyone gets the same SOC (System On a Chip) and the device is performing the same. It isn’t feeling that special as a ‘custom’ special designed chip for Nintendo and they were a bit bending the truth but okay.
What is worrying me is the storage board Tech Insights have discovered. They found a Samsung KLMBG2JENB chip. iFixit found a Toshiba THGBMHG8C2LBAIL in their device.
While both chips are Compliant with the optional command queuing feature and the secure write protection feature of JEDEC e·MMC Ver.5.1 fit in the same size and operate up to 85 °C the performance with a probability of 99% will not be the same.
Not cool Nintendo!
