The Intel 80486.
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.
The Intel Pentium Pro was the first Intel processor to contain level 2 cache.
The first processor to contain L2 (external) cache was the Intel Pentium Pro.
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.
Robert Noyce invented the first integrated circuit chip later on in his time he created two companies one being Intel
The Pentium Pro had both an L1 and an L2 cache on the CPU.
If you are thinking of the Jack Kilby integrated circuit (see image above) of 1958, it was only a one transistor analog sine wave oscillator - not all parts of a computer!It was not until 1971 that Intel put a complete 4 bit CPU (the Intel 4004) on an integrated circuit - but not all parts of a computer.One of the first integrated circuits to actually put all parts of a computer on one integrated circuit was the Intel 8048 microcontroller in 1976.
The first CPU to use the Single Edge Contact (SEC) cartridge was the Intel Pentium II, which was introduced in 1997. This design allowed for a more compact and efficient way to package the processor, along with integrated L2 cache. The SEC cartridge helped improve thermal management and facilitated easier upgrades for users.
SSE was first used with the Intel Pentium 3 III.
Not sure if it's the first but:"Intel processors later than the 80486 integrated floating-point hardware on the main processor chip" source: http://en.wikipedia.org/wiki/Coprocessor#Modern_PC_coprocessorsCouldn't find anything about Motorola processors with math coprocessors built-in.I believe AMD was just behind Intel with the processor design.
