Possible Benchmark Improvements
It would be nice to see a low-end and a high-end CPU also compared on the same test bed in the dual-core and quad-core categories.
Additionally, one could try to make comparisons with Windows and Mac to see which operating systems take advantage of new features like added cores and sse3-sse4.1 best.
To mention nothing about AMD.
I know this is tough since many sites (Tom's Hardware comes to mind) benchmark processors in Windows, but comparatively few do on Linux!

Rarely do I post here anymore.

That way, when someone post his from a Q9XXX, you will know. You can't expect Michael to have all those processors.
As soon as I get Phoronix Test Suite installed, I will post.
Don't get me wrong. I love the Phoronix Test Suite for what it is, and I'm very grateful to Michael for providing this critical piece of software for free. Also, I have no reason to believe Michael isn't acting with his best intentions. However, I'm with everyone else on this issue: It's hard to make a judgment call with just one chip that's been overclocked.
(tl;dr) Put shortly: Perhaps a follow-up article with community-submitted benches of comparable systems would be something Michael could consider.
just my 2c.
(btw, didn't mean to single you out, gtrawoger. nothing personal!)

meh ... no offense taken. I just thought I'd point out the intent of Michael's providing the command for the test. I actually thought it would be a pretty neat idea to have the community provide some benchmarks from their rigs and have larger pool of stats to pull from.
Now, all we'd need now is a way to make something out of that data.

So, I installed Wallbuntu 9.04 Beta 1 on some spare space I had on this HDD here.

The problem with Hyperthreading on multi-core is the scheduler needs to know which cores are virtual and which are not. As the whole point of hyperthreading is to hide such information...
Virtual cores sounds great in theory, but don't always work out. It is possible to get a scenario where the schedulers mess up and load 4 threads on 2 cores, and the two virtual cores, and leave the other two cores unloaded. This is not a problem once you hit 8+ threads (strictly speaking 7+), or when you only have one seriously heavy load thread, but any where in between there is scope to get it wrong. On a single core system, this is, of course, totally irrelevant as it isn't actually possible to assign processes to the "wrong" core.

The core i7 is more super scalar than the P4 and should be able to scale much better.

Below is a full battery of tests from a phenom2 x3 which seems to generally outperform your original phenom.
If anything, the global test results database is a PITA to navigate. I tend to agree with most folks on here. Benchmarking a single platform is about useless. An existing frame of reference...*some* frame of reference would be nice.
