Comparing two CPU's

[Tweak19]

Hey guys so I have the Pentium D extreme edition http://ark.intel.com/products/27614...me-Edition-955-4M-Cache-3_46-GHz-1066-MHz-FSB
and the Pentium Dual core E2220 http://ark.intel.com/products/32430/Intel-Pentium-Processor-E2220-1M-Cache-2_40-GHz-800-MHz-FSB

Now, According to CPUbenchmarking the E2220 series has a higher rating by roughly 500 points. Besides the listed differences from the Intel website can you give me more info as to why the Extreme is slower while gaming? It's quite a noticeable drop in frame rates. My motherboard was installed with the E2220 fresh before I popped in the other one, would this be the underlying cause? My logic tells me more cores & hyper threading would make the extreme edition the preferable choice of the two. Where am I going wrong? Is it the difference in architecture?

E2220 is a Conroe chip, the other is a Netburst....

So yeah, the difference is in architecture.

Would overclocking the Extreme be possible to match the E2220 stock?

Speed of one core=IPC*clockspeed
Speed of multiple cores=(Speed of one core)*(core scaling)
For multiple cores, it is simply a matter of scaling. Anywhere between 1 to the max number of cores can be utilized. It's not always the case extras cores are utilized, it is coding-dependent, but since there are many of processes running in the background, Dual Cores are usually well-utilized and give plenty of snappiness to the system, but the individual cores need to be fast enough.

Netburst is junk. When Core came out we tried hard to imagine Netburst never existed, but truthfully there's still quite a bit of it out there, which is too bad.

Save yourself some time and don't bother with the Pentium D. Really. You might be able to give it away, maybe.

With all that said, performance is similar in the Anandtech Bench, but the EE has a much higher clockspeed.

go the other way around and overclock the conroe. those can take quite a good bit of OCing.

First thing if your motherboard supports it, take it directly to 1333 fsb, set your ram back down to default speed, and turn the multiplier down until the clock speed is around 2ghz. then ramp up clock speed multiplier by 1 until it loses stability and ratchet back one or one half multiplier, and go for ram in the same manner.

My old conroe took 3GHz.

Maybe but it would suck far more electricity to do so and would chuck out a lot of heat. Its inefficient junk.

Collectors might be interested in it as its an EE but for practical purposes... yeah junk.

As far as the E2220 & overclocking I have the Asus p5n-D which has auto settings to clock I just set it to 20% and called it good to go. Suggest the most stable clocking software and I'll mess with it for a few days. I also have the Zalman CNPS10X. nifty little heatsink & so I should be able to push it pretty hard as far as air cooling can take it without burning a hole in my motherboard. See, I found a XPS 600. the fully featured PC at the dump & thought wow this is handy. Complete with Pentium D extreme, Sound Blaster & either 7600's or 7800's in SLI. Patriot DDR2 RAM. All in all quite an unexpected find. Definitely a worthwhile back up pc or to stream multimedia stuff.

E2220 is a Conroe chip, the other is a Netburst....

prescott vs conroe ? at ~mhz ? should be a nobrainer, conroe for the win.
