The Taiwan Semiconductor Manufacturing Company (TSMC) has revealed a manufacturing technique (called wafer-on-wafer or WoW) that could allow CPUs and GPUs to take their first step towards vertical scaling:

Instead of one wafer per chip, future GPUs may include two or more wafers stacked vertically, which would double the performance without the need to develop new horizontal designs every 2 years. A dual wafer setup, for example, would be achieved by flipping the upper wafer over the lower one, binding both via a flip-chip package. Thus, future GPUs could include multiple wafers in one die and the operating system could detect it as a multi-processor graphics card, eliminating the need for SLI setups.

One shortcoming for this technology would be its lower manufacturing yields for sizes lower than 16 nm. If one of the stacked wafers does not pass the QA, the entire stack is discarded, leading to low yields and poor cost effectiveness. TSMC is currently working to improve this technology so that sub-12 nm processes could equally benefit from it.

Not discussed is how to deal with the heat generated in such a stack.

    A lot of websites are using redirect loops until javascript is running to keep spiders/crawlers from getting onto their website unless javascript is enabled.

    Don't much appreciate it, but more and more sites seem to be using it.

    Maybe it's Google One [] deleting all of your files.

      I doubt they are being deleted, the user is just losing access to them then they are being archived somehow. Do you have reason to think otherwise?
