Single core performance comparision: https://www.cpubenchmark.net/singleThread.html https://www.cpubenchmark.net/singleThread.html Intel Core i3-4370 @ 3.80GHz 2,215 pts Intel Pentium 4 @ 3.80GHz 822 pts But to make a fair comparison, one would have to throttle the memory to the speed of a 2004 memory chip. Then the CPU single core performance increase will be a lot less. Also the Pentium 4 architecture was a crossroad and Intel switched back to Pentium 3/M for Core. So a better comparision is the fastest Pentium M with a modern Core CPU. Intel Core i7-4760HQ @ 2.10GHz 1,922 pts Intel Pentium M @ 2.10GHz 660 pts Again, the memory speed increased a lot since then, so for a fair comparison, one would have to throttle the memory chip. The Atom 330 vs current gen Celeron (haven't found J3060, but his bigger brother J1900): Intel Celeron J1900 @ 1.99GHz 530 pts (10 W) Intel Celeron J3060 @ 1.60GHz ? pts ( 6 W) Intel Atom 330 @ 1.60GHz 251 pts ( 8 W) The performance increase of the cheapest Intel CPU hasn't increased that much since 2008, as I said.
