Which CPUs do you love or hate

[Karlos]

@ Karlos: you won't find much logic when Amigans start bashing "competing" platforms

I'll let top answer that:

Code: [Select]

I take it that top reports every thread as a separate CPU? an octocore, nice

If graphs are more your thing, the standard gnome system monitor shows a separate trace for each core (as does windows task manager). Or if you prefer the console but top is too spartan, htop shows a bar for each core and one for memory usage.

Hi,
 
Like : 6502 ( Apple IIc rulez :p, my first(s) asm coding lines )
like 68000 ( Amiga 500 )
like 486DX2 266Mhz ( My first PC was with this CPU :p Duke nukem power)
love 68060 (superscalar, fpu all in 1 cpu :p)
don't like : Intel / AMD cpus (too poor in registers for coding comparing to 680x0/6888x cpu(s)/fpu(s))
don't like : Dual/Quad core : they show the lack of progress in CPU technology
 
Regards,
AmiDARK

If you think they are less evolved than single core CPU's running at higher clock rates then you must have a pretty one dimensional view of processor development. Just recall the P4; an exercise in marketing the "MHz myth". One core on my Q9450 at 2.66 GHz does more work per MHz than the 3.2GHz P4 at work. And there's four of them.

It astounds me that amiga enthusiasts, who, let's face it evangelised pre-emptive multitasking as the holy grail of OS design fail to appreciate how multicore CPU's are the hardware equivalent. Four cores means that 4 threads can each run at any instant, unlike a single core CPU wherein (even given HT) only one process is running at any given moment.

You don't even need specially written massively threaded software to appreciate multiple core, just run a few big CPU hogging apps concurrently and you see the benefit immediately.

It is rather astounding that Amiga folk are so disparaging about anything invented after 1990.  When I bought my Amiga back in '85 it was *because* is was top of the line hardware, has this community became a hangout for luddites?  The Amiga was created out of cutting edge hardware pushed insanely beyond it's limits. That's what I bought into in 1985 and that's what I still want now.

The multicore chips were the best thing to hit the market this century.  The old single core P4's are dogs compared to even the lowest end dual cores.  I've got a pair of quad cores in my main computer and am astonished at the rendering and video capabilities of it.  Try a lot depends on the GPU, but as Karlos says, even basic multitasking is a heck of a lot faster and smoother.  I will never go back to a single core for my main machine again.

I even notice a massive difference on my lowly AMD64x2 especially in some games that seem to make good use of dual core .

[koshman]

Actually when I first started using multi core CPUs I didn't think it was a quantum leap compared to single core (I don't use multithreaded apps often). It was when I was forced to go back to single core a month ago when I really felt the difference. Even when doing simple tasks such as web browsing or burning a DVD the computer can become unresponsive and generally not pleasant to work with. Funny thing that before I first got a dual core CPU I had never noticed that

Borcholli core - love.

Over clock or over cook!

Single core CPUs were never a good idea, especially when we started to demand multitasking... But technology just didn't allow us more than one chip as complex as a CPU in a home computer... but now it does, and I would say two cores is the minimum any computer system should have... my iPhone is the only computing device I use at home with a single core... and hopefully Apple can sort that out soon

Well they got you to shell out for a locked piece of hardware that doesn't belong to you and needs their permission to do anything with, so I'm sure they can do just about anything!

Maybe,

I'd like to help clear up that little myth about the locked nature of the iPhone, if you use the iPhone SDK you can install any app that you compile yourself (and you can give that app you compiled to up to 100 friends) on your iPhone.

It is only if you want to sell/distribute an app to unknown people that Apple then require approval... which is fine with me, I'm having fun with my mobile device...

[persia]

I've jailbroken my 3GS, it works so much better that way.  Gotta be careful about backgrounding things though, they still suck power in the background...

Is the sock feeling jealous yet?

Surprised noone mentioned the Phenom2, has great price/performance and very good upgrade shcemes where you didn't need a new motherboard.
It also seemed to have solved the so called performance problems of the original Phenom which a bigger/better cache or whatever.
It's also almost like a favor in the name of competition you're doing in buying these too...

I haven't used many other processors, let's see: 68000, too slow, 020, too slow, 040 good price/performance back in the day, but could have been better, 060 was very good, almost like a pentium but expensive..
I had a Phillips MSX VG8020 back in the day, but I was just a kid and mostly played cool games:) It was graphically better than the ZX

And when they can have an operating system that is able to perform operating system tasks in parallel thats when we'll really feel the benefits of multiple cores.
