Since phones are aiming towards 7nm lithography, when can we see a new die shrink for the Raspberry Pi CPU?
The current Broadcom is like what, 28nm?
With the introduction of the Pi 3, the performance was boosted, but also power usage has risen above 2,5x the earliest models!
If you ask me, I'd love to see Pi expand in 3 sectors:
- Ultra low power systems (running at a few milliwatt), for R&D, robotics, data logging equipment,
I think this can be good for college, univ research, and help with many projects that require low computing power needs on a budget.
- Standard pc on a bankcard, for end users (what current Pi is about).
I think this is what you currently are already offering, for us fans.
- Micro Servers, high performance, low power.
I think this is for funding the Pi foundation and help in R&D.
Servers can be sold with a slightly larger profit margin, to companies, and individuals, and should help the Pi foundation in research and development.
And I'd really love to see a Pi server, basically a Pi, with multiple sockets per board (basically running 1x LPDDR3 or LPDDR4 ram (1-8GB), with 3 additional slots (up to 64GB of RAM) for expansion, and between 1 to 10 CPU sockets where one could click additional CPUs on, for extra processing power).
Pi Servers would do well in bitcoin farming, webspace hosting, file uploader, mini search engines, Folding@home, file encoding, micro supercomputer, CAD design, or any program that can make use of multiple threads or cores); running Linux or a Pi-derivative OS.
Intel and AMD are going the way of 10 core, 20 thread systems. I want to see an ARM based variant that's affordable.
Pi-like servers like this might very well outperform massive servers of 10 years ago, at only a fraction of the power usage.
Thinking about shoe-box sized servers.
Any more documentation on overclocking a Pi?
Using a thermal camera, seeing which parts get hot with overclocking, and providing info on what chips or components need extra cooling?
How far passive or active cooling can bring a pi?
How about liquid cooling?
I've always felt, on an old style Windows 98/XP computer, that 1,6Ghz is the absolute minimum for a CPU to give a snappy response (dragging windows, browsing,... Since Windows 8 (with increased browsing capabilities), this has become 2,4Ghz.
I often wonder how any normal browser like Firefox, Chrome, or Chromium would handle with a single core 1.4Ghz CPU?
