For some context, here's the conversation that has been had:
Quote
Again you are only speaking from theory, we are talking about WinUAE not a real Amiga, with the 030 no JIT on WinUAE you don't do anything with it if you have to run AROS or run Porting or Amiga RTG systems.
- Which doesn't make much sense since if you use 060 without JIT you will see an hit on speed just the same.
I think you know little about WinUAE, if you try to run AROS 68k 060 without JIT, it will take you twice as long to start AROS, moreover everything will be slower, this is more than ascertained, i have always proved that my tests are always true.
- Which was exactly what I told you....

Yet, even after I tell you that what you're saying is EXACTLY what I've said, you then keep on the same tirade...

No (if the Italian translation is not the other way around) you wrote  "Which doesn't make much sense since if you use 060 without JIT you will see an hit on speed just the same" and this is not true, have you watched the video?, AROS 68k without JIT is unusable because it is too slow !!

Which was what I said, don't take it from me, let chatgpt tell you:

The statement, "Which doesn't make much sense since if you use 060 without JIT you will see a hit on speed just the same," appears to be discussing the performance impact of using a technology or feature referred to as "060" without "JIT" (Just-In-Time) in some context. However, without further context or background information, it's challenging to provide a precise explanation. I'll try to break down the components of the sentence to make it more understandable:

"Which doesn't make much sense": This part suggests that there is something being discussed or proposed that the speaker finds illogical or unreasonable.

"if you use 060 without JIT": Here, "060" seems to be a specific technology or setting, and "JIT" refers to Just-In-Time compilation, which is a technique used in computer programming to improve the runtime performance of code.

"you will see a hit on speed just the same": This means that if you use the mentioned technology or setting ("060") without employing JIT, it will negatively impact the speed or performance of the system. In other words, using "060" alone will still result in a decrease in speed.

In essence, the statement appears to be arguing against the use of "060" without JIT, stating that it would be illogical to expect good performance in such a scenario, as both "060" and "JIT" are likely intended to work together to achieve better performance.

I was not referring to the CPU but to the fact that between an A1200 and an A4000 there are differences, specifically an A1200/060 is not comparable to an A4000/060, as mentioned those who have had both like me can confirm it.
You know that what drives the OS is the CPU right? So what does set A1200/060  A4000/060 apart? I am really puzzled on the differences you find between the two machines regarding their speed... could it be Syspeed, AIBB, Sysinfo, giving A4000/060 that higher values? Surely not against my machine, because the values were about the same. Can it be rendering times from 3D rendering programs? Well, one more time, not from my experience, the A4000 was faster? Yes, but not that much, and surely nothing you can see in daily usage on your machine. And do you know you can have RTG through BVision?

So regarding the Operating System user experience, what set these two machines a part?

Apparently either my translator or your translation is incorrect, you are repeating the same things as me, but we understand them backwards !

correct the quotes because you are mixing my comments with yours

This is the last comment, in this thread do not continue because I will ignore your messages !

I have almost all the Amiga models, my A4000/060 is infinitely faster than my A1200/030, whoever has an A4000/060 can confirm it.

Since you don't know well WinUAE well, my discussion ends here, I won't answer any more on this thread.
Can you explain where did you brought 030 since I told you I had a 060/PPC combo.
It was mentioned on the previous discussion when talking about which processor is best to be used on emulation / WinUAE, where the supposed "expert" continued to suggest the 060.

I was not referring to the CPU but to the fact that between an A1200 and an A4000 there are differences, specifically an A1200/060 is not comparable to an A4000/060, as mentioned those who have had both like me can confirm it.

In fact and assuming that both machines had the same 68060 and fast memory, there aren't differences.

And here I'm talking about physical machines.

Talking about WinUAE there are no differences at all because the 060 + fast memory + RTG emulation is high-level and it's exactly the same.
