L1 cache speed query

[CurlyWhirly]

I have a Q9650 and after reading this it got me wondering what speed the L1 cache runs at as it isn't mentioned?

The Q9650 has 4x32 KB of L1 instruction cache and 4X32 KB of L1 data cache and I'm wondering if it simply runs at the same speed as the 12 MB (2x6 MB) of L2 cache i.e. 3 Ghz ?

Just curious.

AFAIK L1 caches have always run at full-speed (they certainly do in modern CPUs). L2 and L3 caches often run slower than the core, although in modern Phenom/Core2/i7 CPUs they run at full-speed.

Thanks for answering my query
