Try something like http://www.cpu-world.com/Compare/803/AMD_Athlon_64_X2_3800+_(Socket_AM2__35W__IAA)_vs_Intel_Pentium_D_820.html
(guessing on the cpus, you were a bit vague)

The performance of a given system depends on the task.  Some systems
are better at single-threaded integer calculations, some have more
cores so they're better in a multitasking environment, some have better
floating point optimizations, some have more cache and therefore perform
better when code jumps all over the place, etc.

You need to benchmark the systems for whatever task YOU actually care
about.  Whatever program you're using that makes you think "gosh, I
really wish this system could be faster" -- that's the one you use to
benchmark.  It could be compiling the Linux kernel, or transcoding
video and audio, or calculating prime factors of large numbers, or
first-person shooter video games, or whatever it is that you do.

The above was good advice. There's no such thing as "a general benchmark"; there are benchmarks to test integer performance, benchmarks to test floating point performance, benchmarks to test graphics, benchmarks to test storage, etc. If you don't have any specific task that you want to test, then suffice it to say that both systems are equally slow by modern standards. I'd expect that the AMD CPU is a bit better/has more functionality, but you probably won't be able to tell the difference. The graphics on a 10 year old system are likely to be a bigger issue than the CPU. You'd probably get dramatically better results by replacing whatever the hard drive is with an SSD rather than by agonizing over the CPU selection.
