x264 not using cpu capabilities?

[Eretria-chan]

Everytime I use x264, it only says that it uses:
x264 [info]: using cpu capabilities: MMX2 Cache64
Yet, I know the cpu has capbility for SSE1/2/3 since it's a Core 2 Duo. These are builds from x264.nl.
Is this normal or am I missing something?
:thanks:

Sounds more like a Core Duo to me.

[Eretria-chan]

Is there a difference?
Cpu-Z lists the CPU as Intel Core Duo T2400 type: Yonah.
It also lists it supporting MMX, SSE1/2/3, VT-x.

[Dark Shikari]

Is there a difference?The Core 1 is a pile of crap with the world's slowest SSE unit. The Core 2 is pure concentrated awesome in silicon form.

[Eretria-chan]

Heh. I see.
I take it the CPU I am stuck with is this piece of crap unit, and that might explain why SSE isn't used?

[nurbs]

It isn't used because doing the function in SSE would be slower than the MMX version.

[Eretria-chan]

Ah, I see. So basically it's just a matter of sacrificing quality to bring up speed, then.

[nurbs]

It's not about quality. Lets say with your CPU encoding a frame using only the MMX optimized functions takes 1 second and encoding it using SSE would take 1.05 seconds. Using SSE you'd get exactly the same output, only slower.

[Eretria-chan]

I know, I didn't mean that. I meant that I have to use faster x264 settings to get the encode done at a sane time (to bump of encoding speed).

[Lyle_JP]

Well, if encode time is the one immutable factor for you, then yes, your processor will give inferior encoding results.

[Eretria-chan]

I cannot wait forever for the encodes to complete, because I have finite space and I need to record new videos on an almost daily basis, so yes, encoding speed is a factor.
Buying a new processor is out of the question, so lessening the settings is the only solution here, which is why I asked.
