Only 5000 times faster? That number is way too low. Just look at clock speed. Let's say 4 GHz versus 100 KHz. That's already 40,000 faster. The IPC is dramatically better, well over a 100 times, so let's just use 100 (it's a very conservative number, considering this thing was 4-bit) Now we're at 4,000,000. We've got eight core processors which are not too unusual. Let's be conservative and say we get 4x improvement from eight cores. So, we're at 16,000,000 times faster. It's really quite a bit higher, because I was very conservative. 5000? It's not even close.
The 8080 was the first really powerful microprocessor. Everything before it was really incapable of being a general purpose device.
