AMD Level 2 512k

[HardWareBoss]

Whats the big deal with level 2 cache at 512. My old 500 AMD chip has level 2 cache 512. Still running my comptuer for the past 3 years. So why did AMD get rid of it? Now bring it back IN Barton.

ok, look, all the old AMD chips had 512kb L2 cache running at a fraction of the Cpu speed, and also, this cache was not "synched" with the L1 cache (bad explanation...), so it's not really 512, it covers the whole L1 and L2 architecture

Instead of Rdram, why not just merge 4 Sdram channels...

I'll wager your AMD 500 had actual seperate cache ram chips on the motherboard, right? Because my old k6-3 ran on a motherboard with a megabyte of cache. And it was much, MUCH slower than the L1 and L2 cache that nowadays are actually on the processor die.


I want to move to space, so I can overclock processors cooled to absolute zero.

The original 512 cache chips were off die and placed on the pcb next to the core. This ran at 1/2 or 1/3 core speed.

Now with the die shrink fron 18 to 13 micron we have a lot of free space . The cpu components take up a lot less space.So now we have more room for more cache. with the same die size.

I aint signing nothing!!!

as i know mustang use off die L2 is at 1/3 i guess you speak about K6 but does the cache is on the mothers boards.I may be mistaken as may knolege og K6 is about to ZERO

the k6-3 cpus had on-die full speed L2 cache.. but only 256k. the cache on the mobo then became L3 cache and varied between 512k and 1024k and this ran at fsb speed.. ie 100mhz. hope this helps

I'm out of my mind, but feel free to leave a message.

256k was common too.

I was saying about Slot-A Athlons. They had 1/2 speed L2 cache for slower clocked models like 600 MHz, 650 MHz. Later they used 2/5 speed L2 cache, and finally with 1 GHz Athlon they used 1/3 speed L2 cache

Later they used 2/4 speed L2 cache

That would be same as 1/2, isn't it? I think you meant 2/5.

Good or Bad have no meaning at all, depends on what your point of view is.

Thanks for correction.
