Fastest 8-bit computer?

the 680x0 series is 32 bit, BUT as explained a gazillion times, the chipset-width is 16 bit only.
not just the chipset.. the data bus of the mc68000 is 16 bits as well.
One of the fastest in 80s could've been Philips Videopac +G7400 .
Intel 8048 clocked at 5.91MHz

stop feeding the Troll!
Currently I was interested in the Sam Coupe. Or for a long. And Sotsoft too for some reason. And they have Roger Jewitt too. So, it must be good!
But seriously, it's interesting late 8bit. Ok,. Z80 6Mhz, but less if point to vram. 3.5 disk drive yey. Maybe just write stuff on PC on disk and copy and play. More stuff. Interesting video rams. And it's linear. I have seen some demos/games, wow. Looks cool, more demos should we see for it. Maybe more stuff, don't remember. But,. too expensive on fuckin ebay. Maybe I'll just use emulator.

Well, I didn't even got a CPC+. More rare maybe.
But I have the GX4000.

1. Make an EZ80 based computer
2. Port Doom
3. ....
4. Profit!

Commodore 64 is fast because it has an custom VIC-chip
The Sam Coupe has some nice hardware specs for an 8-bit machine, but I don't think anyone would call speed one of its strong points. As I understand it, when they were setting the specs, they failed to increase the processor speed in proportion to the larger amount of graphics data to be shifted around, which is why most of the developers shied away from action games (and it ended up with 90% of its games being puzzle games instead).

CPC in space.
@Optimus: In ebay there are occasional CPC+ses available. Got mine from there (1 working, and second semiworking one).
Yes, the MSX in space probably travelled in excess of 2km/s in its orbit, so it's undoubtedly the fastest 8-bit home computer :D
There is also this:
I guess any Z80 compatible CPU experiment card would still be 8 bit and like 50MHz. As for actual computers, I don't think you can do better than the late Z80-based ones. All the other families seemed to have stepped directly to 16 or 32-bit, and Z80 still had a use for CP/M so there was a market to make faster CPUs for.

"Hit Bit in Orbit" - MSX2 Sony HB-G900 in space!
"A sony 900 has boldy gone where no MSX has gone before... into space! To celeberate the 25th anniversary of the Apollo mission, German televisionbroadcasted American and Soviet space footage. Whilst watching images of the interior of the Russian space staition Mir, Gerd Pepela recognised his computer - a Sony 900 with genlocker. He managed to capture this on video. The pictures are a little fuzzy - but you'd recognise your own machine anywhere, wouldnt you? Mir was launched on 19 February 1986 to an orbit of 241 miles."

Still, more rare than even Sam Coupe. I find again two Sam Coupe bidding. But CPC+ I have to see for months any.
Yeah it is rare. I scoured french and spanish ebay for mine.
Sam Coupe sounds interesting also, but i guess lady living at same location won't really like any "projects" at the moment ;) (Had to go to great lengths to justify acquisition of PowerMac G5 some time ago...
If experiences of gettin C64s in Finland are in any value, i guess quite many old 8bit computers were put to scrap bin or for recycling without realizing any of their value. Used to go these recycling points to salvage stuff time to time and sometimes there were 8bit/16bit machines, but lately there have been none.

I read somewhere "Hello, in our work the 64bit computer is not enough, is there a way I can buy an 128bit or even 256bit computer" hahaha and I lolled. It was like the "Atari VCS is it 4bit?" joke. Or someone tells me PDP-8 had 12bit and another person who does not understand other than marketing thinks it should have graphics between amstrad and amiga. hehehe..
Anyway, I wondered, how would be a 4bit, 2bit or 1bit CPU be? Would be fun to build.

Optimus: Texas Instruments TMS1000 had 4-bit registers. But these days, the "bit-depth" of a system is usually measured in the width of the address bus, not the registers. And I'm not sure how useful a 4-bit address bus would be.

The intel 4004 was also 4-bit I think, registers just big enough to hold one BCD digit (it was designed for calculators).
