You may have thought so but you were incorrect.
There were two basic versions of the Slot-1 600 (both also came in
100Mhz
and 133MHz FSB). The first had the same 512K, half speed, cache as a
P-II
and the second had on-die 256k full speed cache, exactly the same as
the
s370 and, in fact, nothing but the s370 processor ’on a cart’ so it
could
plug into a slot-1 motherboard.
The on-die 256k, full speed, cache is significantly faster than the
512k
half speed cache so either your ’slot-1’ 600 P-III would be identical
to an
s370 P-III 600 or significantly slower if it was the earlier 512k
cache job.
Point taken with the different versions, I recall we had some 550mhz
slot
one systems that had a 133mhz FSB and 4X AGP slots.
They could have been 533 MHz (4x133) but it's impossible to have 550 on a
133 MHz FSB with the available multipliers. 550Mhz is a 100MHz FSB speed
(5.5x100).
Specifications do
not always ring true to performance though.
Actually, they do. It's just that people often misinterpret specifications
and think then mean things they don't, such as thinking 8x AGP will be
'twice as fast' as 4x simply because the number is twice as big or that
512K of cache will be faster than 256K (I.E. not realizing the other
important factors).
To be fair, quantizing it isn't always so 'obvious' to even those 'expert'
in it either.
Some early 370 socket
systems were not as good as the computers I’ve just mentioned . Not in
the real world anyway
Well, an s370 socket "system" is a whole different thing than speaking of
the processor as many other factors affect performance and, just off hand,
I'd venture a guess that your recollection is comparing an AGP slot-1
system to an s370 with on-board shared memory video because the sharing on
those system gobbles up tons of memory bandwidth limiting the amount left
for the processor, and so it's performance. That's not the processor's
fault, though, nor does it mean one **processor** is 'faster' than the
other and I assure you that given a fair fight, meaning all else equal, the
256k full speed cache s370 processors are significantly faster than the
512K half speed cache slot-1s of the same 'MHz'.
