I have no reason to doubt the sources I quoted. Do you have any serious sources for the 68060 using microcode?

No info I can rely on, but if the previous generations were, why change for the '060?
And the '060's design really derives from the '060 (really a kind of super scalar version of the '40).

And I'm trying not to even dignify takemehomegrandma's latest posts.
Apparently he has not been paying attention to your reports on the latest 64 bit ARM cpus.

And my about ten year old G5 beats some of the scores I get with one Core2 based system I have.
Some PPCs certainly beat lower end X64 systems and are light years away from what Amigas started with.

I don't know, but I read that after the massively microcoded 68000, the following m68k generations used less and less microcode, so that the 68040 had relatively little microcode and the 68060 none at all. Maybe it was for performance reasons?

There are significant opcode differences between the two. And as you said, it's a black box, so ISA design of the 060 may be derived from the 040's, but this isn't necessarily true for the microarchitectural design.

I don't remember I said anything about performance. But there you go:

Takmehomegrandma: i have never said that morphos does not support new radeon cards in the future what i say, it's that for me amd64+radeon cards is the best choice. It's not a troll.
For me AMD processors are great, i use a ATHLON64 X2 since 2008 and it's allways suffisant today. I like also intel processors but the are a little more expansive.

I think you may have a point on the '60 performance.
It may also point to why Motorola eventually gave up on the series.
It would make it much more work to create new cpus.

"However, when it comes to performance-per-watt, APM X-Gene 1 is clearly ahead of Intel Xeon E5-2650 and there’s no comparison against Xeon Phi systems."

OK, lower performance than X64, but...

Introduced yesterday:

https://en.wikipedia.org/wiki/Apple_A9
https://en.wikipedia.org/wiki/Apple_A9X

Details are sparse so far. The core has been enhanced over Typhoon (aka "Cyclone gen 2") no doubt. Naming of the new core and performance parameters will trickle through eventually.

Edit: A9 is dual-core at 1.85 GHz clock rate.
Edit2: The new core is named Twister.

Apple are claiming it's faster than something like 80% of laptops sold in the last year.
Bit of a bold claim but most laptops sold will be low end, on some benchmarks ARM have been hitting around low end laptop scores since the A15.

Talking of which, this was an interesting comment:

"2016 will be the year of the ARM laptop" - Linus Torvalds.

http://news.softpedia.com/news/linus-torvalds-say-2016-will-be-the-year-of-the-arm-laptop-494044.shtml

For servers, the APM X-Gene 1 isn't exactly the best poster child as it's built on a process 3 generations behind. The results should be much better on a more up to date process. Haven't heard much recently but X-Gene 2 was due soon with 3 fairly soon after.

However, now the big boys are getting in:

That article sums it up - Intel is finally getting competition from a semi vendor almost as big as they are.

This is the newly announced chip:

OK, that is interesting.
Of course I need to connect it to external devices that render the $9 price less relevant.

Don't bet on it.

Good thing he just focuses on a kernel based on UNIX (and doesn't really dabble in OS', other software, or hardware).

At what point did we start worshiping the opinion of a creator of a plagiarized work?

BTW - I'm not satisfied with Android or ChromeOS based ARM laptops.

Come to think of it, I regularly consider ditching my Android based cell phone for an iPhone (but the idea of joining that zombie horde troubles me).

Pretty easy, consider the man's position on micro kernels (are you aware of it?), and considering the real time OS I have used them under in the past.
And as far as 'facepalmimg' goes, what kind of kernel does MorphOS use again?

I was able to load and unload drivers under earlier OS' long before I could do it under Linux based ones.
That still isn't the case in all instances under monolithic kernels.

Maybe you should discuss this with Ralph, not me.

And you are never joining the dark side.
YOU have a sense of humor and that is not allowed there.

And, again, I am against deifying Linus.

Hello!

Somewhat off topic, but Jim, for about equivalent price of an iThing (iCing), there's the Neo900! It's not android nor ios... The project is in progress, pre-orders are ok! I just now haven't the money for it but as soon as, I go!
I have for now two N900's and it's a pleasure not to have always stupid permissions to let to any apps!!!!

Off topic, but ti's ARM afterall! And even the N900 with it's little Cortex A8 is quite efficient under Maemo...

MorphOSian salutations!

Yes, you had a point then, and I didn't care for Linux anymore back then.
I just didn't expect to get a hard time from Kronos about it.
Its like hearing a good friend has decided to only buy Apple hardware and clothes from the Gap.

@Jim
I'm sure there is a terabyte worth of Usenet posts you might want to catch up on the topic of mikrokernels vs. monolithic ones.

Other than that the main difference between Linus and Ralph is that one reimplementation of a popular OS is a million times (literally) more sucessfull than the other.
