The 2 current applications don't have intel x86 CPU support, yet there are tons of x86 Intel CPU's on the CPU models page, why?

And when will the project get x86 Intel CPU support for the 2 current applications?

Can you give an example for a x86 Intel CPU on that page? I see there only x86_64 CPUs, both from Intel and AMD.

I wouldn't expect support for x86 CPUs, doesn't make much sense to introduce that for n-Body now even if it would be possible. I mean we are talking about Pentium 4, AthlonXP and older CPUs, pretty much anything after that was x86_64 and is supported by the current applications. I strongly doubt there are many such old computers still running BOINC. Far more important would be a look at this thread and adding support for modern instruction sets, which could make the application more efficient and actually speed up the project. Considering the relatively low CPU temperatures and power draw compared with other applications, the n-body application does not seem to utilize CPUs very much, actually large areas seem to be idle or even shut off when it is running.

The Separation project, which shut down two years ago worked on 32-bit, N-Body doesn't and don't see how it ever will, since 32-bit support is getting removed, not added.
Why I had to switch off MW@h at that point, until I got this new computer, since the old one might have had a 64-bit capable CPU just fine, but the OS was 32-bit, since having a 64-bit one on a computer with 4 GB RAM and no dedicated video card would have only increased the usage of that already limited memory for no benefit.
