Socket 370
8 months after introduction of Katmai core, Intel released first processors with Coppermine core - new Pentium III core based on 0.18 micron technology. Better manufacturing technology resulted in smaller die size of the CPU, and with smaller die size it became economically feasible to incorporate 256 KB level 2 cache on the die. Although the size of integrated L2 cache was two times smaller than the size of L2 cache in previous generations of Pentium II and Pentium III microprocessors, the advantage of the cache was in its speed as the cache was running at processor frequency, while back-side cache of older Pentium processors was running at half of the processor frequency. The new L2 cache utilized 256-bit data path to the cache, which was 4 times wider than on Katmai processors. The cache had lower latency and included "Advanced System Buffering" feature. Intel referred to this cache as "Advanced Transfer Cache". Increased speed and other improvements in cache design compensated for smaller cache size, and overall performance of Coppermine processors with Advanced Transfer Cache was on average 10% faster than performance of Katmai CPUs with bigger, but slower, back-side L2 cache. Coppermine processors also had lower power requirements than Katmai processors due to lower core voltage - 1.5 - 1.75 V as opposed to 2.0V for Katmai core.

By integrating L2 cache on a die, Intel eliminated external cache chips - the main reason why the bulky slot-type cartridge was required in older Pentium II/III CPUs. With the new Coppermine core it became possible to put the processor on smaller and cheaper PGA-type plastic package. Unlike older socket 370 Celerons and Pentiums in plastic PGA packages, new Pentium III package didn't have integrated heatsink. On one hand this was an advantage as it allowed more efficient cooling of the core. On the other hand CPU installation procedure became more delicate as it was possible to accidentally damage the core during heatsink installation. The new package had 370 pins and required socket 370, though this socket 370 was not compatible with original socket 370 used by Mendocino Celeron processors. For new Pentium III processors Intel revised electrical specifications of socket 370, as a consequence new Pentium III processors would fit into older motherboards, but would not work there.

Not all Pentium III processors were manufactured in the new package. To support large installed base of Slot 1 motherboards Intel continued to release Coppermine Pentium III processors in Slot 1 package. These processors had the same performance and other characteristics as socket 370 processors.

Coppermine processors were produced in speeds ranging from 500 Mhz to 1000 MHz. Intel announced and shipped limited quantities of 1133 MHz processors, but shortly after announcement the 1133 MHz processors were recalled.

I have a Tyan S1854 Trinity 400 mobo, with an Intel Pentium 3, coppermine 600EB. I have it overclocked to 632mhz, with the FSB at 140. i have 320megs of RAM, and an Radeon 9600SE card. It runs anything i need it to, except for some of the newer games. i have had no trouble with it, except for strange sqeals in the downloaded cd music, but i think that may be the Hard disc.

Do these procs not need fans (passive cooling) due to the nm shrink? I recieved one with just a big aluminum heatsink on it, looks like this.

Response: I believe they still needed cooling by external fan either blowing air over the heatsink or pulling air from the heatsink.

served me well

i have a dell dimension 4100 with the Coppermine 1ghz cpu, go it right after it came out. upgraded everything i could on it, managed to make it last til late '06. Currentally it has 512mb of that silly old SDRAM and an overclocked 256mb 9600. Somehow this processor managed to run Battlefield 2, yet got owned trying to run Half-Life 2. PC's next stop...oil cooling project.

Though old, still makes a good working system.

I have an old PIII 1ghz in a system I built myself with 512mb of RAM and a Radeon 9200 video card. It runs Windows XP SP2 quite well. I use it for lots of basic stuff, but it also runs older games like Starcraft, Counterstrike, and even Lord of the Rings:Return of the King quite superbly.

Thanks for the presentation! I am from Bulgaria and I have IBM NetVista PIII with CPU Intel Coppermine Socket 370 133x6=800Mhz like Michel's. The OS is Win Xp Sp2. I have also 512 SDRAM/133Mhz and 128MB ATI Video. Counter-Strike Source runs without problem but I prefer v1.6 . Salutations for all!!!

Fans

They actually run pretty cool and can get by without direct fan airflow. A rear case fan behind the CPU may be needed though so there is some airflow. I have a 600E pulled from a Dell that has no fan on it and runs around 45C typically.

well enough !

I have a PIII 1ghz in a system I built myself with 512mb of RAM and a TNT2 16 MB video card, 4 x usb2 PCI card, PCI TV tuner. It runs Windows XP SP2 with internet browsing, DC++ downloads. It plays movies and TV tuner at 80-100% cpu load, sometimes slow, and if a download/transfer is active it becomes slooooowwwwww... but still, is a pleasure to see it still does his job well!
