Pentium III info on ark.intel.com

I'm trying to verify some information for a legacy system, and looking to find an exact replacement for a cpu with the SKU/part number, RK80533PZ006256.

When I look up this string on https://ark.intel.com/products/27531/Intel-Pentium-III-Processor-1_13-GHz-256K-Cache-133-MHz-FSB?q=R... ark.intel.com, it is listed as a Tualatin chip.

However, every other place online, such ashttp://www.cpu-world.com/CPUs/Pentium-III/Intel-Pentium%20III%201133%20-%20RK80533PZ006256.html CPU-World, it's listed as a Coppermine chip.

Doing further research shows a similar inconsistency for many of the higher-clocked Coppermine chip S-Spec, where Ark lists it as Tualatin instead.

In one case I found a http://mixeurpc.free.fr/SITE_x86-guide/Photos/Grandes/20/cu_1133_sl5b2_costa.JPG photo of a chip which has the voltage printed on it, but when I look that one up on Ark, the voltage is different.

Could I have a verification as to whether the part number RK80533PZ006256 corresponds to the S-Spec SL5QK and is a Coppermine chip?

Hi repaxan,

In the Photo is a SL5B2 (RK80526PZ006256) and that is a Coppermine.

The SL5QK (RK80533PZ006256) is a Coppermine T

80525 = Katmai (0.25 µm)

80526 = Coppermine (0.18 µm)

80533 = Coppermine T (0.18 µm)

80530 = Tualatin (0.13 µm)

Intel probably listed the last used name on the ark link.

When you go to the first link in your post and click on: Ordering and Compliance you can see that 80526, 80530 and 80533 all have a 1.13GHz / 256K Cache / 133MHz FSB model.

you can find more information about the Pentium III models on a wiki page.

Hope this helps.
