Indeed.

The funny part is that IPC actually diminishes at higher frequency.Since memory clock stays the same , the wait for memory becomes greater wrt to CPU cycles , thus you're burning more cycles doing nothing.

What I want to link is an article which is by all means excellent in describing the current situation :

Not correct.

From what I understand, what Jacky was getting at with the cache latencies being reduced at a high clockspeed is actually correct. When going to RAM, the processor has to go through all the cache levels of the processor, including the 'slow' L3. The latency of the L3 cache is proportional to a speed (not sure on the terminology) that is increased when the clockspeed is raised. Therefore, with figures quote on the Tech Report site, the cache latecies are 23ns on the slower 2.0Ghz chip and 19ns on the faster (2.5Ghz) chip.

Therefore, increasing the clockspeed could result in what would seem a higher IPC.

Also, TG Daily slamming AMD with a pro-Intel bias? Well I'll be damned...

EDIT: Also, after more careful reading,

Without separate voltage domain, though, the 2350's memory controller drops to 1.6GHz. That matters quite a bit more than you might think, in part because the L3 cache uses the same clock.

And correct me if i'm wrong, but the motherboard doesn't support split power planes, so the memory controller would have been running at 1.6Ghz. Based on that fact alone, we should see improved performance from the new mobos.
