Worthless benchmark, as it gives no information on the setups used.  Maybe the Pegasos had a different form of RAM than the A1 and Athlon.  Maybe they had different kernel revisions or configurations.  What cards are in each machine?  What about the hard drives, that can throw off results too.

Without this data, those benchmarks are worth less than the bandwidth used to download them.

The problem is, no data about the actual hardware used.  What video card, HD, RAM, etc.  Any and all of these can schew benchmarks off by up to 30% in any direction, depending on the benchmark.

Heck, I remember a benchmark where the hardware was chosen specifically to cripple a particular OS for an OS 2 OS comparison, causing an artificial "boost" in the sponsoring company.  That's why public disclosure of the hardware is so critical.

It was in context to what BBRV just said here.


But you were the one that started it with a forum topic not more than 2 weeks ago.

@Alkemyst

Nobody is claiming any of that, I pointed out that you made the original claim, pulling text out of context to push an agenda without providing a link to the original post in order for people to read that the comments posted were a responce to Ben Hermans.  That means, frankly, that you did the post just to mislead people and to generally troll.  And now you'll respond in like here, attempting to act all clean while blaming others for the problems of the world.  So go ahead, do it, I'm prepared.

I just got the lowdown on the A1-G3-600 and Pegasos used for the tests:

The A1-G3-SE had a 133Mhz FSB
the Pegasos had a 100Mhz FSB

And the Pegasos kept up with a machine that had a 33% higher clockspeed for memory access.  Means that the tests were predominantly held in the L2 cache, and therefore do not deny nor support bbrv's original claims.

Why didn?t they set both motherboards to 133 Mhz (or 100 Mhz) FSB?


Neither board was set up to go against the other.  They were benchmarked seperately under different conditions.

IF BBRV?s claims are generalized in terms of scope then it would be countered by this specific benchmark scenario.


But they were not, they were focused on a specific section, responsiveness.  So, a CPU-bound benchmark will not reveal how well the I/O tasks are handled on each board, which is where responsiveness is measured.
