i was comparing processors on a site i found and i saw 2 things on each which i dont know what they are. it said

level 1 cache x
level 2 cache x

(wher x is the amount of kb :knock: )

what is this? lol never seen it before. Plus i need to know whats better, choose from below

1.
level 1 cache :128kb
level 2 cache :256kb

2.
level 1 cache :16kb
level 2 cache : 1024kb

i'm not sure whats better as one is even but one ahs a gigh level 2 lol and considering i dont know what this is, makes it hard to tell :p

thanx
 
The higher the cache the better it is basically information stored on the chip is a pretty good not techie explanation....
 
but whats better

right i get it all now, but i still dont know what of the above i mentioned is better, any ideas?
 
wot i thought

umm its a pentium 4 chip :S lol and i dont know why it has 2 levels. possibly one is external and one internal? heres what it says about it neways

Processor Manufacturer: Intel
Model: Pentium 4 2.4 GHz
Processor Speed: 2.4 GHz
Bus Speed: 533 MHz
Socket Type: Socket 478
Level 1 Cache: 16 KB
Level 2 Cache: 1024 KB
 
yet another

heres another intel chip, 3.2mhz but still got a low level 1 cache, lower that the first :S:S this this chip seems very powerful

Processor Manufacturer: Intel
Model: Pentium 4 3.2 GHz
Processor Speed: 3.2 GHz
Box Includes CPU, Fan & Heatsink
Bus Speed: 800 MHz
Socket Type: Socket 478
Level 1 Cache: 8 KB
Level 2 Cache: 512 KB

this has got me very confoosed :confused: :unch:
 
I think l2 cache is more important.
I don't understand the l1 cache, look at this.link
It says l1, 12+16. Why not write 28? Or are there 2 kinds of l1 that they are distinguishing.
 
hmmm

i aint got a scooby m8, i dont really understand. And it only seems to be certain processors that have 2 levels. its got me stumped lol. and i still dont kno wot ones better out of the top 2 i mentioned, as one is balanced outish and the other has a realy high level 2 :knock:
