On the image from [1], I see 5CSXFC6C6U23I7N (110K). It seems to be rather expensive $300, 3 times the price of the whole MiSTer board. [1] https://retroremake.co/products/mister-pi-retro-gaming-fpga-...

Do we get also realtime (10ths us latency) out-of-the-box, where badly written drivers cannot negatively interfere good ones?

Here [1] someone asked to make RP1 I/O chip available, but actually RP2350 is what would fit the purpose. [1] https://www.raspberrypi.com/news/rp1-the-silicon-controlling...

RP1 I/O chip on RPi5 has so many high-speed interfaces. I've been thinking RP2350 could be some smart I/O chip for a PC/notebook/network attached computers (with only 1 necessary high-speed connection).

> 1 × USB 1.1 controller and PHY, with host and device support Sure, after integrating USB 2.0 HS or 1Gb-Ethernet the pico2-board will cost more than $5. So, integrated high-speed interfacing with PC was not a nice-to-have option (for sp

I'd wish memory bandwidth could also be doubled so often on desktops. Instead of 256 (even more due to 2-3 times higher core frequency) only 14 times increase: DDR-400 6.4 GB/s => DDR5-5600 89.6 GB/s. The machine balance k

What are W-ratings of the power supplies for N-series and RK?

Yeah, that's exactly where I've learned this from. It's just the very huge price if you need this board in Europe, which stays in the way.

Intel N97 seems to support a so called In-Band ECC with non-ECC UDIMMs, thus there is a slight performance hit (both memory bandwidth and processing resources). I'm curious whether N100 does support it too, though considering a huge di
