Something doesn't match.
Celeron ≠ Pentium 4

I've been getting the same 'we understand the output better than the author and it's wrong' thing the whole yesterday over here:
http://gathering.tweakers.net/forum/lis ... /1081538/0

There is no Celeron architecture, doesn't exist.

If you want a list of architectures that do exist, see here:
http://gcc.gnu.org/onlinedocs/gcc-4.0.2 ... tions.html

And don't even get me started about the people who try to interpet the flags themselves.

Edit:
Here's a list of all the flags and meanings behind the ones I know.

Although I have some ideas what the unknowns are, I'd rather wait for someone to post accurate info than have myself guess.

However most of the unknowns are Transmeta and VIA stuff, and a few newer Intel stuff.

Yes a WinChip CPU.

lflush mmx fxsr sse sse2 syscall nx mmxext fxsr_opt 3dnowext 3dnow lahf_lm

Why is my cpu showing up as a K8? AoL's cpu had this id, but Nach attributed it to the cpu having 64-bit capabilities. My cpu is 32-bit, though.



On a side note... Is there a lot of difficulty involved in adding all of these optimisations?
Will Nach include EVERY cpu that have had their info posted in this thread?
Finally, what kind of extra speed has been noticed so far? That last question is probably just for Nach, unless anyone else has been given a test build.

Oh thanks for that, seems like you found a second bug, got to go fix.

[kieran_]

Sweet! You answered while I was editing!

Kieran:
Please redownload and make sure it's fixed.

Edit:

Not at all. And since all the hard work is already completed, it's really easy to make any neccesary fixes.

Will Nach include EVERY cpu that have had their info posted in this thread?

For compile time yes!
So far I have no intentions of doing anything runtime, but you never know.

Finally, what kind of extra speed has been noticed so far? That last question is probably just for Nach, unless anyone else has been given a test build.

Hard to say especially if you used to specify your CPU manually when compiling. Although those like pagefault who used to set it to i386 notice quite an improvement.

Edit:
I changed how the Pentium/Celeron M was detected since it seemed too risky to me. For all I know there is a Xeon M
Those with the Intel M flavor CPUs please redownload and make sure it's still correct.

[kieran_]

Thank you for ansering my questions. I have downloaded the file, but my pc is at home, so you'll get the info tomorrow. Cheers.

Um... probably not.. since it was very limited in anything... the speeds were around the 100-200MHz range... and must less "in existance" than say the last known Cyrix processors.

So... I don't think it to be worthwhile to optimize for Winchip... perhaps maybe the very few Cyrix users there are...

[Jipcy]

Mine outputs the same as before.

Updated. BTW thanks for pointing that out, I didn't realize I had to check if CPUID existed first. Although we're using the ZSNES version of CPUID detection instead of what they recommend.

I have an IDT WinChip but i don't have a motherboard for it. I also have a NexGen P90 but I don't have a board for that either.

I have around 300 different processors, from 386SX to 486DX-4 to 5k86 to K5 PR200 to K6 to K6/2 to Pentium to Pentium MMX to Cyrix MII to IBM MII to Pentium Pro to Pentium Overdrive to VIA C3 to Pentium 2 to Pentium 3 to Athlon to Duron to Applebred to Athlon XP to Athlon64 to Pentium 4 Dual Core (smithfield) EM64T to Xeon


Which of those don't you have?

p.s. I can just cat /proc/cpuinfo on those, I don't run winders remember. But it returns the same information. Yeah. Yeah.

From everything, the only thing I don't have data on are the WinChips, K6-2, C3-2, Athlon 4, Athlon MP.

Although after studying it all, the WinChips are the only ones that worry me since I managed to get other CPUs in the same family of the other ones I'm missing, so I feel rather confident in my prediction of the results for those.

p.s. I can just cat /proc/cpuinfo on those, I don't run winders remember. But it returns the same information. Yeah. Yeah.

It's not the same information. We don't use the same techniques as Linux does for some of it, hence why a few cases worry me. For example you'll notice by the Pentium 3s reported they don't list the internal name with my program, but /proc/cpuinfo has a model name since they generate one based on other things it knows about, but the name itself isn't actually written in the CPU for those.

You can however get my program for Linux.

Uh... here is my info. It's an AMD 64 Sempron which should be the same thing as the smaller core Athlon 64s but someone decided to take a shit on half the cache.

C:\cpuopt.exe

It's a k8? Whaaaa?!?

This would have been a lot easier:

[Clements]

Yes, it's a K8. All 64-Bit Semprons are K8s.

[Cyrus]

Yes, it's a K8. All 64-Bit Semprons are K8s.

I thought k8s were only the AthlonXP series. Are all AMD 64 cpus of the k8 series or just the shitty Semprons?

Edit: Nevermind, I just looked at the other posts. So ya, I guess that means 64bit Semprons really aren't physically the same thing (-50% of cache) as the Athlon 64 counterparts.

What information do we need from him exactly?

Well, stuff (hints) that would improve your cpu detection algorithm (seems like you're having some slight issues, but nothing significant)
