According to these numbers, the Phenom scales approximately equally well at all FFT sizes, whereas the Core2 doesn't scale well at all at small FFT sizes (in fact, 3 and 4 threads perform worse than 2 threads). You can see the Core2 walks all over the Phenom (88% faster at 768K, around 150% faster at 3072K and 8192K). The Core2 scales very well to 2 cores (about 90% efficient), but Core2 with 3-4 cores and Phenom with 2-4 cores are around 50-65% efficient.
On the TF side, the Core2 again dominates, showing numbers 117% to 159% faster than the Phenom.

Admittedly these are numbers from a TLB-bug-affected Phenom9500, so numbers may look different with the new B3 versions just appearing now. When I see a system with a 9x50 Phenom I'll see if I can grab some benchmark numbers.

Phenom9500 was running Prime95 25.5 on Windows XP Pro 32-bit.
Core2 Q6600 was running Prime95 25.6 on Windows Vista Premium 32-bit.

James... thanks very much for the phenom benchmarks. This has been very useful in helping me decide on my next build. The price of the phenom is sweet, but the performance of the Core2 architecture, overclockability and energy consumption is more compelling. Perhaps the Phenom will become a better choice without the TLB bug and also if AMD manages to ramp up the clock speeds. It's still a very new architecture, while Intel has had lots more chance to tweak the Core2.

In the end I went for the Q6600 'G0' stepping and PC8500 memory - overclocks nicely to 3GHz without even a voltage bump, been prime stable for last 12 hours.

Facit: Do not underestimate the DRAM-Bandwidth! Phenom is a good mprimer and bang for the rel. powerconsumption and the buck! mprime is the one tool testing out phenoms potentials!

I'm glad you posted your results. I'm about to buy a new processor, and was planning on Intel, but now I'm leaning towards the Phenom 9850. Do you have results for it at 2500 MHz?
