How much L2 does the AMD K6 II 450MHZ have?

??

none...

it is all on the motherboard. I've seen boards varying from 256K to 1Mb.

Yup! to what datallah said.

The K6-3 and K6-3+ had 256KB of on onboard L2 cache.

The K6-2+ had 128KB of onboard L2 cache.

The 8088 had none.

So it has no on-chip L2 cache, thanks.

 

[formulav8]

It has 32KB of L1 Cache, but no onchip L2.

K6-II's have no on-die cache, K6-2+/K6-3+/K6-3's all have on-die cache.

Actually the K6 line has 64kB L1.

K6-2 has 0k L2, K6-2+ has 128k L2, K6-3 and K6-3+ have 256k L2. They all have 64k L1, and L2 or L3 cache on the motherboard as well.

<< The 9.3-million-transistor AMD K6-2 processor is manufactured on AMD's 0.25-micron, five-layer-metal process technology using local interconnect and shallow trench isolation at AMD's Fab 25 wafer fabrication facility in Austin, Texas. The AMD-K6-2 processor is packaged in a 100MHz Super7 platform-compatible, 321-pin ceramic pin grid array (CPGA) package.

The K6-2 incorporates the innovative and efficient RISC86 microarchitecture, a large 64KB Level 1 cache (32KB dual-ported data cache, 32KB instruction cache with an additional 20KB of predecode cache) and an improved floating-point execution unit. The MMX unit's execution speed has also been tweaked, addressing one of the criticisms of the K6. At its launch in mid-1998 the entry-level version of the CPU was rated at 300MHz - by the end of its product cycle, the fastest processor available was a 550MHz version. >>
