What Cpu have you?

It was put on Socket 7 boards because the processors of the day didn't have any L2 cache, later processors had the L2 cache integrated into the processor and so motherboard based cache was no longer needed. The AMD K6-3 was the odd one out as it had onboard L2 cache but worked on Socket 7 boards thus making the motherboard cache L3

Processor speeds have increased rapidly over the years but FSB speeds have not increased at the same level so any motherboard based cache would really be to slow now to have any beneficial effect on performance.

Current:

K6-2 500
Athlon T-Bird 1.33GHz

taz i can see what you are saying but when the K6 500mhz was about the FSB and on board cache speed was only 100Mhz or 1/5th of the processor speed. however with the current DDR memory and 266mhz FSB then the cache could also run at 266mhz and five times this is almost 1.4ghz meaning that there is the potential for it to be usefull even now.

micron made some chipset samples with large ondie l3 caches... I'm not sure if they were considered cost-effective, though the caches did increase speed quite a bit.

[Novdid]

That chipset was called "mamba" if remember correctly and that L3 cache was something very special cause it had >8GB (or was it 8MB of cache? ) of bandwidth and it was included in the northbridge, correct me if I'm wrong.

And I know they claimed atleast 10% speed increase.

Mamba was/is not a complete chipset but only a northbridge
with 8 MB of integrated L3 cache. From what I've read Micron
was considering to enter the chipset market with Mamba
but it seems they've dropped these plans.

I have ticked Duron, but I did until it recently went tits up & took my Abit KA7 board with it have a Athlon classic 750mhz.

My preference is the Athlon for its greater power - so when I can afford it I will grab myself a new socket athlon

Never seen one of those. But I have worked on and coded asm for 6809 and an HC11 in the process of getting my engineering diploma at NAIT.

One time I had bought an "upgrade" chip for the 8088, named NEC V20 (8088) and V30 (8086). I paid maybe $11cdn for it - happened to be the last one Radio Shack had. can't remember the year i bought it though...

Oh yeah, actually seen 3MHz 80186 in an Acer Altos. Next time I saw one of those chips was on a VLB caching controller. Too bad it never had a driver for windows95...

sorry, i'll stop now ...

i have a Vic20 networked to a Commodore 64!


jk

actually its 2 Wangs


ok, ok, not really! But my friend has an Amiga.

The 6502 was the original gaming CPU as I recall. Anybody remember using bit-slice processors?

And what about poor Zilog? Everybody forgets the big "Zzzzz".

[Taz]

I remember programming machine code on my BBC Micro which had a 6502 processor running at 2Mhz. It's was very limited to say the least with only 3 registers IIRC.

[Indiana]

Yes, the 6502 is sometimes described a bit ironically as the "first RISC" CPU. That means very few instructions, but doing them in very few cycles as well....

It was Commodores C64 CPU, running at an astonishing 1 MHz (2MHz in the C=128), for those that are too young to know CPUs slower than 1GHz...
