I was confused about clock speed vs bus speed performance in Pentium III. The Pentium III 1 GHz has higher clock speed but lower bus speed, the 933 MHz counterpart has lower clock speed but higher bus speed.
So which is better? 1000 MHz or 933 MHz?
Take the 1000/100 and OC it...
1000/100 won't go far. FSB is king with PIIIs. For coppermine, I recommend a 933/133 which can go 1050/150 easily. Getting a 1000/133 to 1125/150 is diffcult and the added voltage will usually kill the chips.
Best outright PIII is a Tualatin 1.4s 1400/512/133, which can go 1600/152 easily. Like mine. 😁

Depends on the board. If you can't overclock it, choose the 933. Bus speed can make a pretty big difference with a PIII system, especially under Win2K and XP. My 1400-S really took off after overclocking it to 1585/151 and tightening the memory timings. The thing just screams!

And mine. Although one thing I noticed is that the L1 cache took a bit of a hit at 1596/152. At first I thought that Cachechk was spitting out bogus numbers, but my 3DMark01 score also fell by a couple hundred points. So on my machine, 1585/151 yields the best performance.
This could very well be a motherboard or BIOS-related issue. I use a TUV4X (VIA 694X) board.
If you want to put up with "quality" VIA chipsets or lack of ISA slots, then sure 😀
For you guys overclocking your Tualatins, what Cachechk7 memory read/write speeds are you getting? At 150+ MHz, I assume the system is set to CL3. Even CL2 PC133 RAM only goes up to 143 MHz, so you'd have to use CL2 PC133 RAM on a CL3 setting for 150 MHz to work reliably with the RAM.
On a non-overclocked dual Tualatin III-S 1.4 GHz, I get the following in Cachechk7 using CL2 PC133 RAM,
Read: 775.2 MB/s
Write: 472.9 MB/s
The best, and fastest, way to run Cachechk7 read is with this command: cachechk -d -t6
The best, and fastest, way to run cachechk7 write is with this command: cachechk -w -d -t6
Plan your life wisely, you'll be dead before you know it.
I'm just curious, is anyone using the Coppermine-T variant that fell between Coppermine and Tualatin?

coppermine-t has the same cd0 core stepping as the latest coppermine, just slightly changed VIO standard.

If PIII 933 MHz was socket version, is it work on my HP Vectra VL600 that using Slot 1 via Slotkets? It was compatible I think

933Mhz P3s are available in Slot-1 form.
Crimson Tide - EVGA 1000P2; ASUS Z10PE-D8 WS; 2x E5-2697 v3 14C 3.8 GHz on all cores (All core hack); 64GB Samsung DDR4-2133 ECC
EVGA 1080 Ti FTW3; EVGA 750 Ti SC; Sound Blaster Z
Confirmed, I am using a Slot-1 933 Mhz Coppermine.

I know if there Slot 1 version, but I saw on eBay socket version only (no slot version)
And then there's this one

The infamous SL4HH that was recalled for being slow, unstable, and buggy as hell.
The P3 933 in my sig is a Slot 1.
