Intel Lynnfield CPU Bests Nehalem In Performance/Watt
Vigile writes "Not many people have debated that Intel's Nehalem architecture is the fastest available for consumer desktop computers since it was released last year, but quite a few have complained about the cost of the platform. Intel just released new Lynnfield-based processors under both the Core i7 and Core i5 names and tests are showing the new CPUs beating Nehalem in both performance-per-watt and performance-per-dollar tests to a startling degree. And while raw performance probably still goes to the Nehalem-based Core i7 CPUs, the lower prices of motherboards and memory for Lynnfield processors will likely more than make up for it." Update: 09/08 14:03 GMT by T : There are more eye-wateringly exhaustive examinations of the new chips all over the Web; here's HotHardware's version, and Tom's Hardware's.
and btw, is that the best fuckwad pseudo you could come with?
"Soft-dicked dweeb" or "babbling-fucktard" would have been more appropriate.

She's too indulgent with you, kill yourself, turd!
Smile, don't click...
What? You call yourself a Pedant and you did not pick up the erroneous use of 'effect'? Geez, what is Sloshdat coming to - we cannot even trust the Grammar Nazis and Pedants anymore...
Excuse me, but please get off my Pennisetum Clandestinum, eh!
That's one of the reasons I got a Mac. I got fed up with Windows, fed up with the GPU mumbo-jumbo and fed up with the CPU mumbo-jumbo.
I want a desktop or a laptop. I have X money. I have very few choices with limits I can understand (CPU speed, max RAM, installed GPU+RAM, etc). Since only the Mac Pro uses a different kind of CPU, all the other Macs can pretty much be compared by CPU clock speed alone.
By definition, if it isn't a Nehalem die, it's not Nehalem, even if it's just a "tock" variant (die shrunk - see Intel's "tick/tock" roadmap) of Nehalem it's still a different chip design.
In this case, the CPU has significant design differences from a Nehalem CPU. There's a lot more than just removing some pins from the package. The CPU had to be changed significantly (one DDR channel removed, QPI replaced with DMI) in order to allow those pins to be removed.
The removal of QPI in favor of DMI (much slower but simpler/cheaper) is a *significant* difference.
For someone who attempts to talk with such authority on the subject, you sure talk a lot of crap. Intel themselves, refer to the Core i5 as being members of the Nehalem microarchitecture family:
"The new Intel Coreâ i5 processor family, two new Intel Coreâ i7 processors and the Intel® Xeon processor 3400 series bring Intel's latest Nehalem microarchitecture to mainstream desktop and entry server markets."

How about a processor with 0 power consumption?
Of course, it is 0 performance...
Infinite performance per watt!
Performance per watt is a useless measure. People should use lowest power in a desired performance envelope. But that is not a single number you can use in a sound bite...
