The first Intel CPU to feature external cache was the Intel Pentium Pro. External cache is also referred to as L2 cache, while internal cache is called L1 cache.
Federico Faggin and Ted Hoff were the chief designers of the first Intel chipset called "Intel 4004". The Intel 4004 was a 4-bit central processing unit made from 1971 to 1981.
The first microprocessor was the Intel 4004.
4004 is the first general purpose microprocessor by Intel
Intel 4004
The first single chip processor was the Intel 4004. It ran at 764 khz (yes that is kilo hertz)
The first processor to contain L2 (external) cache was the Intel Pentium Pro.
The Intel Pentium Pro was the first Intel processor to contain level 2 cache.
80-48 6ds
The Intel Pentium III.
The original Intel Celeron processor was not as popular as expected because it lacked the level 2 cache to help reduce the price of the processor. With no level 2 cache, the processor acted much slower than the competitor processors.
The original Intel Pentium was the first to have a 64-bit data bus while it's predecessor, the i486 was the first to feature an on-die L1 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.
The Intel 4004 introduced in 1970 and was the first processor introduced by Intel.
Intel's first microproceesor was 4004..
The Intel 80486
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.
The first intel processor introduced in 1973 called is Intel 8008
