Sorry, Marcus. My email once again sent just to you.
I would suggest a used Core i5 PC. The i7, IMO, is just a 10% better i5 for 150-200% the price.
You'd be surprised how much computer you can get if you buy just a couple years out of date. The new ones are only marginally faster for almost double the price. I jumped on a Newegg deal for a used 3rd Gen i5 with a 2x4 GB RAM arrangement, to which I
added a 2x2 GB set that brought it up to 12 GB while maintaining dual-channel. The cost, if you get a deal like mine, need not be much more than $450 or so. A brand-new PC that price could not approach this setup, performance-wise. I would also suggest Windows
7 x64 for maximum performance, but you're probably a Linux user.

Note that the FX series (at least, some of them) use a shared FPU arrangement.
Having said that, I have an FX-8350 system that does fairly well with 6 receivers operating at 2.56Msps, doing correlation interferometry (computing 15 visibility functions in parallel for the 6 receivers).

I would go for more real cores. Back when I was doing CGI, I thought the
Pentium 4 with HT would be a good idea, but it wasn't. On that CPU, the
logical Intel cores only do integer operations; floating-point can only be
done on real cores. It's probably the same on the modern chips, otherwise
they'd just say 4 real cores. So even though I normally favor Intel PC's,
if these 2 are your only choices then I would suggest the AMD.

I'm buying a new computer and two possible options will be intel
i3-6100 and AMD FX-4300.
Performance using GNU-Radio may be the key to the selection of one or
the other.
I guess the more cores the CPU, the better the performance.
FX-4300 is 4 cores, i3-6100 is only two cores but they say both of them
runs 4 threads.
I should think that a real core (AMD) will work faster than a "logic"
one (intel), but reading benchmarks it seems that i3-6100 beats FX-4300
..... but what with GNU-Radio?
Anyone has test both?
