The L1 cache on a Pentium 3 (And most all processors) is divided into two caches, the data cache and the instruction cache. This may be because the instructions tend to have a high spacial locality while data has higher temporal locality. At any rate, all 4 variants of the Pentium III used 16Kb data cache and 16Kb instruction cache, which makes 32Kb total.
(The size of L2 cache varied based on the core.)

What type of RAM is in an Intel Pentium III?
The L1 cache in the Pentium III is SRAM.
Does an Intel Pentium III processor have an L2 cache?
Yes.
What is the difference between an Intel Pentium III and an Intel Celeron processor?
Celeron refers to a line of processors from Intel. They are low-cost counterparts of Pentium II, III, 4, M, and D processors. They differ mainly in the amount of L2 cache. Celerons have a smaller L2 cache, which is basically a buffer in the CPU to avoid slowdown. With a smaller L2 cache, Celerons perform slightly worse in some processor-intensive applications.
Which CPU runs at the highest speed between classic Pentium Pentium III Pentium 4 or Pentium 4 with HT technology?
Pentium 4 with HT technology runs at the highest speed.
How did the Pentium 4 chip get its name?
The Pentium 4 got it's name because it was the next series of Intel's flagship CPU line after the Pentium III.
What is an Intel Pentium III?
An obsolete type of CPU chip, popular about 10-12 years ago (late 1990s). They replaced Pentium IIs, and were replaced by Pentium IVs.
What was the first non-server processor to have a L3 cache?
Some RISC server CPU designs have had L3 for many years. The first consumer CPU that could use an L3 was the AMD K6-III, in 1999. However, it didn't have an L3 cache on the die, but used the motherboard-based L2 cache present on almost all Super Socket 7 motherboards as an L3. It did have on-die L2, and was designed so that it could use the external cache as L3. The first consumer CPU to have on-die L3 was the Pentium 4 Extreme Edition, a rebranded Xeon introduced late in 2003 to counter AMD's new Athlon 64. Xeons, which are server CPU's, have had L3 since 2001.
What does an Intel Pentium III Xeon do does it replace an Intel Pentium III?
No. It is a higher-end version of the same processor, with a larger amount of L2 cache. It cannot be used as a replacement, since they use different slot / socket types.
How does an Intel Pentium D CPU 3.20ghz compare to an Intel Pentium III?
It's often difficult to compare the performance of two processors, especially when one is much older. Depending on the type of computations you are doing, you may see anything from no change to a 1700% increase in the Pentium D over the Pentium III.
What is an Intel Celeron?
AnswerA Celeron was a cost-reduced version of an Intel Pentium II, Pentium III, Pentium 4, Pentium D, or Pentium M. It was made cheaper by not including as much L2 cache (the first ones had none at all), and was aimed primarily at the lower-end market.
When was Pentium III created?
Pentium III was created in 1999.
Why was the Intel Celeron introduced when the Intel Pentium III was introduced?
It wasn't. It was introduced back when the Pentium II was introduced. The Celeron was created because the L2 cache chips used in the Pentium II were rather expensive, and they wanted to provide a low-end alternative.
