Can MB990 (Macbook Pro 13 inch 2.26GHz) user test your cpu vt support?

Just curious whether p7550 cpu supports vt-x.
Can you please run
sysctl machdep.cpu.features
from terminal to see whether vt is supported. Thanks.

btw, if p7550 list vmx feature, does that mean it will have the same performance for parallels/fusion/... as P8400?
If yes, what's the difference between this model and mac mini 2.26GHz (I mean CPU, that is p7550 vs. p8400)?
Can one virtualize win xp in win 7?

Thanks.
 
No one with Macbook Pro 13in 2.26GHz Here?

Just open the Terminal from Application/Utilities, and execute this command:
sysctl machdep.cpu.features
then paste the result back to here, pretty easy.
Thanks for the help.
 
Here's what I got when I ran that:
FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT PSE36 CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM SSE3 MON DSCPL VMX SMX EST TM2 SSSE3 CX16 TPR PDCM SSE4.1

Hope this helps, BTW my parallels runs just as well as it did on my SR MBP (T7500 processor)

Here's a link to Intel regarding the specs of the P8400. VT-X is supported.

OK, Thank you very much!

I can see that VMX is supported.

btw, mb990 does not use P8400 processor, rather, it use P7550.
you can run
sysctl machdep.cpu.brand_string
to confirm that.
 
This is from the 13" MBP:
machdep.cpu.brand_string: Intel(R) Core(TM)2 Duo CPU P8400 @ 2.26GHz
 
I've also noticed it on a couple of review sites, but I had remembered seeing P8400 when I ran Geekbench. It's definitely a P8400.

Thanks for the reply.

Maybe mbps sold in different countries use different processors?
where did you buy your mbp?

And I would also like to hear from the P7550 users...
I cant find information about this processor on Intel official site.
 
I bought mine in the US. I have my doubts that they're different in different countries, but I've seen stranger. Also, if you search P7550 in Geekbench there are tons of results for MacBookPro5,5. Are they interchangeable?
 
I got P7550. Purchased at Apple Store Pasadena.

And, even though the P7450 doesn't support VMX (according to Wikipedia), mine does list it when using the Terminal command above.
 
I thought that it would after doing some searching around. It appears as though the P7550 is just the OEM version of the P8400.

Mine was purchased in Ann Arbor, MI at the Apple store.

That's great. screensaver400, Thank you for your information.

Can you also provide more detailed output here?
1. the result of "sysctl machdep.cpu.features"
2. the result of "sysctl machdep.cpu.brand_string"
3. Is it able to run Parallels? (Parallels cannot be installed on machine which doesn't support VT-x)

Thank you very much!

If this model fully support VT, I plan to buy this model, and upgrade hard drive and memory later.

I got it...
Version numbers are always confusing.... umm:(

Thanks a lot for your detailed explanation!

I use VMWare, not Parallels. I'll see about downloading a trial tonight if I get a chance.

What does vtx do? Will the low end 13 mbp have it? If I plan on doing a lot of windows stuff would it make a big difference?

- vt-x feature (i.e. VMX instructions in CPU) enables you to run virtual machines much more efficient than just software simulation.

- low end 13 mbp == mb990 discussed in this thread. as screensaver400 and crzdmniac reported here, it supports VMX.

- depends. if you use windows in boot camp, or do not enable hardware virtualization in your vm software, then there is no difference at all. else, say you want to run windows in Parallels on Mac OS X, then there will be a big difference between with or without vt-x support.
 
I also have the P7550 in my mid 2009 mbp

I confirm that it support vt (terminal and virtualbox)
 
I run Windows 7 in Bootcamp and when I run CPU-Z and NWinfo32 both programs report that I have Core 2 Duo P7570 with VT support. According to Intel CPU specs 7550 does not support VT and 7570 does.
 
my mbp 2.2ghz Santa Rosa processor supports it and it's almost 3 years old..so i'm sure all modern processors have this
