Wifh 134k transistors and 49mm2, that's 365um2 per transitor. The N3 node from TSMC is quoted as ~300Mtr/mm2, so I believe 365um2 is 109k transtors, so I guess

Wifh 134k transistors and 49mm2, that's 365um2 per transitor. The N3 node from TSMC is quoted as ~300Mtr/mm2, so I believe 365um2 is 109k transtors, so I guess it means just under one 4004 could fit in the area of a single 1982 transitor. That said the Mtr/mm2 number is not the whole story, often single gates like an inverter could be made of many transistor, fingers, dummy gates, etc, so the effective number is lower. Would be interesting to see how many inv/nand/FF/SRAM was in the 4004, as it would be easier to get a fair comparison.
What calc did you have?

- ido 4y agoThe 4004 only has 2300 transistors, not 134k.
- d_tr 4y agoYou got the wrong numbers for the 4004! The 4004 had just 2300 transistors in a 12 mm^2 area. So, today you can fit 3*10^8 * 12 = 3.6*10^9 transistors in that area, or 1.5 million 4004s, or 650 4004s in the area of the old transistor.
- klelatti 4y agoThanks - this was my calculation but with, I think, one generation older node density - hence the approx 2x factor difference.
- tails4e 4y agoThanks for the correction, I was looking at the 286, not the 4004! Not sure how I managed to get the wrong chip... Though someone mentioned the 286 in a comment below, so I guess I muddled that in.
