Hi,

for the usual 'older cpu vs old cpu' question, today I ask your opinion into this fight, the Pentium 4 661 3,6Ghz (Cedar Mill) vs the Pentium Dual E2160 1,8Ghz (Allendale).

Thank 😀

Another question I don't understand... why the P4 Prescot 3,4Ghz on 478 in the FPU Raytracing benchmark of linux give somthing like 50 points and the P4 3,6Ghz Cedar Mill on 775 gives like 9 points (lower = better)??? Was there some changes in the FPU?

Cedar Mill is just a die-shrink of Prescott-2M. There are no architecture changes. And 50 is much too high. My Prescott Celeron-D at 3.2 GHz manages about 23.7.

Here are the full benchmarks of that Celeron:

Blowfish 15.7
Cryptohash 113.65
Fibonacci 4.53
N-Queens 9.44
FFT 9.55
Raytracing 23.69

Also the Raspberry Pi 3 B+ have better values on FPU, need to test it again something was probably wrong.
