Intel Clovertown: Quad Core for the Masses

AS3AP Transactions/Second
The 2.33 GHz Clovertown shows a 32% scaling over the 3.0 GHz Woodcrest, not too bad considering the drop in clock from 3.0 GHz to 2.33 GHz. It is interesting to note that the performance of the 1.86 GHz Clovertown is comparable to the 3.0 GHz Woodcrest, which again shows very strong scaling with double the cores and almost half the clock. Ignoring the apples to oranges comparison, the quad Opteron is able outperform the Clovertown 2.33 GHz by as much as 21%.
It's no surprise that Woodcrest ramps up the CPU utilization the quickest. What is surprising is that the Opteron is not able to go higher than 86% utilization. We can only speculate that this high transaction benchmark has uncovered a bottleneck in the Opteron architecture.

You can not read, and understand what I am writting, and I am the dolt or moron . . .Interresting that . . . interresting indeed. I think what I will do, is just ignore whatever else you have to say, just like the majority of other readers seemingly have done.

However if Barcelona comes out and then Penryn smashes it just a few months later, yeah, then I'm gonna be worried about them. :(Griswold - Saturday, March 31, 2007 - link

This is for the authors. Sorry if I missed it, but do the power measurementsinclude chipset power? AMD processors include the memory controller as well,
right? Do the performance/watt take this into account?

We measured power at the wall, but we do not include the power for the disk chassis.Thus, performance/watt takes all of your mentioned items into account.

I am guessing Pernyn will be different enough from Clovertown to make using vmotion (and many other enterprise features) impossible. It sucks enough that we already have two processor families in our Dell 2950's, and here comes one more.I am all for progress, it just looks like this might be something VMware has to address at some point.

...the industry. As usual Intel's "glueblob" is another rushed-out-the-door, knee-jerk reaction to AMD supplying superior CPU products. AMD is really gonna hurt Intel with Barcelona and friends.johnsonx - Friday, March 30, 2007 - link

You forgot to add some "fine-ass".Phynaz - Friday, March 30, 2007 - link
Wow, you really are a moron.
