In 1989, Intel introduced the 486 processor, improving the performance of the 32-bit 386. Unlike the 386, the 486 has an on-chip 8 KB cache and a floating-point unit. The 486 has over a million transistors.
I took this die photo and labeled it with the main functional blocks.
@kenshirriff damn this made me find out that CPU cores are a lot smaller than I thought and occupy less than half of the entire thing, both in modern CPUs and I assume in this one if the decode logic part is what would be described as a CPU core (I don't know that much about computer science)
