Anyway, even if i had the means, i wouldn't do a 68k compatible amiga. I would design my own. |

That's what morphos is doing. They showed an early version in Neuss/Amiga34.

x86 in 1994 weren't powerful enough to emulate 68k properly. It would have been a massive regression.

Do you think only on paper that it could be done ?? 2. what do you think of the progress of intel cpu in the last 10 years vs during 95 -> 2010 periode ?? I don't talk about gfx card, their enhancement are fine, but i feel that the cpu of the pc has slowed those last 10 years ?? What's your thought about it ?? |

Only on paper because it's not going to happen. It is technically possible, but this alone does not decide. Quote:
But it is true that software is more and more bloat as time passes, and this does not appear to be slowing down. While at the same time they reach more and more limits and current cpu power does not rise as fast as it used to. |

Thank you Meynaf,
I appreciate your direct answer. We think the same, but you, you can explain why. I always felt that we should be more advanced now, I can keep a pc now at least 5 yaers, perhaps changing the gfx card one time. By the pas i kept it 2 years because the cpu changed so fast, it'sn't the case anymore. And for the moment Multi Processor is not the answer hoped. Sadly like you said it certainly won't change, we have to hope that they will use MP better. Or that a new technology will happen, do you see a new cpu which could change things or a possible evolution which could shake the world ?? Like the atari st and the amiga did or the pentium doubling frequency really fast or the 1st 3d accelerated cards 3dfx, etc... The cpu evolution (for me) is boring now. Quote:

QPU?
CPU = Central Processing Unit GPU = Graphics Processing Unit QPU = Quantum Processing Unit Because we all want to cheat like nature by predicting angles of possible paths instead of crunching numbers old school, and O(sqrt(N)) is so much sweeter than O(N) according to Grover's algorithm. The reason this future seems plausible is because some clever scientist realized that funding is easy if you claim the new tech can break encryption, regardless if the statement is true or not. https://en.wikipedia.org/wiki/Timeli...ntum_computing |

Does it provide anything that will make programming easier ?
(Same reason ppc didn't qualify as 68k replacement, as its asm is actually much worse.) Can it be made reliable enough so it can provide exactness in the same way as classical computers ? (Actually even for simplest of tasks they need heavy error correction.) Can it work at normal temperature like todays computers ? (Near absolute zero cooler at home would be very funny to have...) Can it be adapted to any algorithm so it can replace classical computers ? (I think it can't, even on the most optimistic paper.) If answer to any of the above is 'no' then for me it does not qualify as "anything good"... Quote:
https://csrc.nist.gov/Projects/Post-...m-Cryptography In addition, the reason you mentioned for a plausible future does not look right to me because if they really reach the goal, they will lose their funding... so currently the best approach is lots and lots of claims and theoretical work, with some apparently successful experiment here and there, to make people believe in it - and this is exactly what we have today. Anyway, if asked i wouldn't bet on quantum computer at all - actually i would bet against it. I think one day they will find a limit, some basic law of nature they didn't know or anticipate, that they simply cannot bypass, and it will remain a lab's curiosity forever. This is just my view on it, it may be wrong of course. But remember nobody can claim to have fully understood quantum physics so who knows what is lurking... |

This graph would indicate to me that Moore's law still hold true
https://en.wikipedia.org/wiki/Moore%..._1971-2018.png As for the original question I'm not so sure moving to PPC would have changed anything. Keep your timelines in check and remember that circa 1992/93 when commodore released their last machines the motorola flag ship was the 68040 at 40mhz. The best intel chip of the time was the 486 dx2 at 50mhz. The motorola at 25mhz can grind out 28MIPS . The 486dx2 @ 66mhz can only achieve 30MIPS so it seems pretty obvious to me that the speeds of the processors was not the problem. In fact you can almost understand why apple and commodore stayed with motorola, they were faster after all. Figures quoted above obtained from - https://gamicus.gamepedia.com/Instructions_per_second It would not be until the Pentium that Intel would pull away but that's not for a year or 2 yet on the above time frame and in the 90s a year or 2 was the lifespan of anything computer related. |

Good point. In terms of physical clock speed that seems to have levelled of a fair bit but with increase in transistor count is there not also an equal increase in speed as operations per clock cycle increase. It's been 20 years since I had a brief look at CPU design in tech so please excuse if that's a stupid question.

sp cpus brute force haven't evolutate so much those last 10 years... That's why they multiply the cores but 2 cores doesn't mean 2xspeed, and if the code isn't done for mp, it means 1xspeed.
Beleive me, i never kept a pc so much years than now !!! I will have to change it surely in 2020, and this time completely. How i would like to see more competions in the pc market !!! My only hope, a big, big society like sony or else, coming shaking up everything... But actually even the biggest seem afraid to do that. Someone could explain howmuch and why the market is so locked ?? |

The reason your PC is still going strong is that hardware performance has been at a high enough level for all day to day tasks for years and it doesn't need to get any faster to browse the web, watch youtube, stream netflix, send e-mails etc. I have a core2 duo rig lying in front of the TV in the man cave and it'll happily stream 1080p all day long. I would build systems for family and friends generally around Christmas time and my recommendation for a budget gaming rig is always to buy the low end of the current motherboard, CPU, ram etc and last generations GPU. There are so many system builders on the likes of facebook and gumtree that are still pushing the old i5 or i7 socket but with that there is no room for future upgrade. You can put together a £400 ryzen build that will run everything these days and give you scope to drop in 32gb of ram and a faster cpu in a few years to keep things fresh. I don't see there being any fresh competition these days though. If Sony entered the desktop market it'd just be off the shelf parts probably an i5, GTX2060, 16gb DDR4 and an SSD and I only use intel and nvidia parts because that's what must lay people see and think performance. For a system I built for a friend of my wife last year I had try hard to convince her that the RX580 was faster than a GTX960 despite costing the same and having a lower number. Its the same argument with AMD vs Intel CPUs. Despite there being really only 3 companies (Intel, AMD, Nvidia) I wouldn't call the market locked as there is plenty of scope for any budget throughout the range of products from them. |

Even if improving single-core performance were easily achievable, there's not a lot driving it right now; as you said, per-core performance has been more than adequate for most tasks for a very long time now. The emphasis is very much on multiple cores for high-throughput server loads, and best performance/power balance for the mobile space; the desktop user's experience isn't really improving much because (javascript-infested-swamps-masquerading-as-websites-yes-I'm-looking-at-you-facebook notwithstanding) it doesn't really need to. |
