Re: [gentoo-user] recommended CFLAGS for Dual Athlon MP 2200

[Håvard Wall]

AMD XP/MP: 128KB L1 cache (64KB instructions, 64KB data)
          +512KB L2 cache
          =640KB total cache
Intel Pentium 4 <= 2GHz:
             8KB L1 data cache
          + 12KB L1 instruction cache
          +256KB L2 cache
          =276KB total cache
Intel Pentium 4 >= 2GHz:
             8KB L1 data cache
          + 12KB L1 instruction cache
          +512KB L2 cache
          =532KB total cache
Actually, P4 have 12K micro-ops cache, not 12KB, whatever that means in 
practice.
Of course, AMD Duron and Intel Celerons are cheaper products with less 
chache.

The easiest way to find the cache size: cat /proc/cpuinfo

On an Athlon 850MHz, I have:
cache size      : 256 KB
