My Q9300 is:

Measured floating point speed 2592.74 million ops/sec
Measured integer speed 5171.51 million ops/sec

So, you run 2 tasks slightly faster (maybe), the Q9300 runs twice as many, and the i7 runs four times as many ... Memory speed is significantly faster and the cache is also larger.

On RaH you would have to look at the number of decoys made in the 3 hours of runtime though this average is not tracked ...

This is the point we raised way back in BOINC Beta about the benchmarks as far as them not accurately characterizing the systems ...

I would say these numbers for the i7 are great because you multiply them by 8.

Compare them to the AMD when you multiply those numbers by 2

The i7 shows

23,456 FP
58,280 for Int

vs.

AMD x2

6,470 FP
11,634 Int

It is only 4 to 5 times the performance. Looks good to me

My i7 920 is takes about 154 sec/credit to crunch. Benchmarks are:
2900 MFLOPS
8535 MIPS

I prefer to run w/o HT, so games run faster. I don't really care about having a high RAC; I crunch for the science.

Here's two lone Core i7's in a sea of Intel Xenon, look at numbers 64 and 72.

Since Bad Penguin wanted to see what one of these does 24/7, I'm going to assume that this is run that often based on the RAC. That's what you get to look forward to when you get your board and memory for your i7. You will have to change your username to Bad Ass Penguin then.

Numbers 91, 93, 97, 102,109,117 also have the i7. I'm not looking any further though, you can do that on your own.

I've had my i7 920 working about a month and a half now. I kind of like it. :-)

Here are the benchmarks as of 5/21/2009:
Measured floating point speed 3059.77 million ops/sec
Measured integer speed 9857.84 million ops/sec

You can look at the machine here.

As an example of how much more computing power we have at our disposal today, here is a laptop I decide to retire, after bring the new i7 machine online. Notice the PC was added to Rosetta on 21 Oct 2005 1:16:56 UTC. It has been crunching basically 24/7 since then, yet has only earned 71,934 credits.

The new machine caught up to the old laptop at right about the 1 month mark. Once it did, I shut down the laptop. 1 month, crazy cool.

Anyway, that's my i7 story. Happy crunching!

Wow. The i7 is about 7-9 times more powerful PER core. so that's 8x9... about 72 times faster. Amazing how technology advances, huh?

My new athlon X2 7850 is smoking my old Athlon 2400+. With the 2400+ my RAC was about 100 a day, and I had been running Rosetta for about 4 years. In two and a half weeks my RAC is in the 600's a day.

The Athlons x2 are just so tightly well made.

My 6400+ @ 3.3GHz at 90nm !! and still runs below 60C crunching for Rosetta.

Under 60C is probably what it is supposed to be. Mine was not, and I found out it is an overvoltage problem that my motherboard has with all AMD processors. I had to e-mail a customer service person, who's e-mail I got on Bulletin Boards discussing the problem, and had them e-mail me the next Bios update, which is not even available on Asus web site. Now it's under 60C, 57C to be exact, but before it was normally 64C.
