Is the L1 cache needed on a quad core processor?

Is the L1 cache needed on a quad core processor?

A lot of quad cores, it seems, don't have the L1 cache... Maybe it is just me, but the L1 cache seems important....

I chose a processor that has an L1 cache of 4X 128KB, and L2 cache of 4X 512KB, and an L3 cache of 2MB. However, that processor since been discontinued on newegg and am having issues finding the processor else where... I am able to find similar ones but, they don't seem to have an L1 cache, just L2 and L3...

Don't these things need the L1 cache?

Which cpus are you talking about? I didn't know there are any current architectures that don't use L1 cache. They usually don't add a lot of L1 cache because the close proximity makes it difficult. There isn't really much room there. L2 is slower, L3 is slowest.

Hey, thanks for the quick replys...

My main concern was that these other chips didn't have the L1 cache.... I thought they where vital to the chip but wasn't sure, especially because it has an L3 cache...

I guess the companies who sell them just don't like to put them on there.....

I'm still looking around for the chip, but it is a hard one to get a hold of...

Not clear from your posts exactly which CPUs you seem to think have no L1 cache.

OK, I think you have answered my question.

But if you look around, they L1 cache isn't listed on a lot of quads, but if a processor needs that cache, it must be there....

Good point. I just wanted to make sure before I go off and ignorantly buy a processor without an L1 cache... That would suck!
