Hello all.

I need to find out what the L2 cache size and FSB frequency of the AMD
Athlon 2500+ are...
Are there different makes of this cpu? How are they to be identified?

Many thanks in advance,
-arifi

512 KB and 166 (*2, if you are a marketing type) Mhz.

There are only Barton core XP2500+s (so far). There may be different
mask set revision numbers, I don't know.

Rumour has it that several (many?) XPP2500+s will actually run at 200Mhz
(*2) FSB, or something close to it, which then makes then equivalent to
an XP3200+, albeit not tested/guaranteed for that speed.

Many thanks!

Apologies for my ignorance on this issue - but does

> 512 KB and 166 (*2, if you are a marketing type) Mhz.

mean that it is a 333 MHz FSB? Or is there a different interpretation of FSB
values for AMD chips (as in the CPU labeling)?
Or is 333 (or 400 in 400 FSB case) always 166*2 or 200*2 and hence the name
Double Data Rate for RAM ?

Best,

Yes, 166Mhz*2 = 333Mhz (which is what marketing like to quote). However
the '166' is what the 'multiplier' is multiplied by to give the actual
CPU frequency, and what you'll have to set on the motherboard/BIOS.

Yes, Athlons all run DDR, and the 'marketing' number is always 2x ..
what the BIOS settings are (BIOS is 100, 133, 166, or 200 Mhz.)

AFAICT, all Athlon XP 2500+ models are DDR333 (/166mhz) FSB Barton (512k L2
cache) models... IIRC, it's a 1.83ghz part.

The 2600+ is IIRC always DDR333 (/166mhz) FSB available in both Barton (512k
L2, 1.9ghz IIRC) and non-Barton versions (256k? L2, 2.03ghz IIRC).

The Athlon uses a DDR bus, so it's effective data rate is twice the
clock speed. The chip uses a 166MHz bus speed, but because it's DDR
the marketing folks always (incorrectly) say that it uses a "333MHz"
bus, just like they incorrectly state that the newest Pentium4's use
an "800MHz" bus.

It's kind of like when people used to say that they had a 9600 "baud"
modem. The "baud" rate, or symbol rate of those modems was only 2400
symbols/sec, but people were still using outdated terminology from the
300bps modem days (a 300bps modem ran at 300 baud). Proper
terminology for the modem would have been "9600 bps" (bps = bits per
second).

Similarly, proper terminology for the Athlon's bus speed would be
333MT/s (millions of transfers/transactions/transitions/t-whatever per
second), or perhaps more importantly, 2.7GB/s.

In the case of DDR memory and the Athlon's DDR bus, yes. The first
few Intel Pentium4 chips used a 400MT/s bus that ran at 100MHz QDR
(QDR = Quad Data Rate, similar concept to DDR except sending 4 bits
per pin per clock tick instead of just two).

The 2600 has been made for 266 and 333 MHz FSB with a 256 k L2 (model 8) and
333 MHz FSB with a 512 k L2 (model 10)

The 2500 only comes with a 512 k L2 at 333 (as AMD would say, or 2 x 166)

For info on identifying athlon XPs, refer to:
http://www.amd.com/us-en/Processors/...4_3748,00.html

A key for the part number on the cpu is in the ordering information
sections.

Thanks again, everybody !!!
Very much appreciated.

Interesting. Thanks for the correction; I hadn't seen the 266FSB 2600+ for
sale and must have missed it.
