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.
I've begun to feel that Intel is lacking focus in their chip lineup. While it makes sense that they have different series for different markets, within those lineups they have too many disparate chips that just cloud the water.
Atom Z vs Atom N is one such case. The Atom is supposed to be their embedded processor series, but they just can't shake off the PC market yoke and focus solely on embedded customers.
They have server CPUs, desktop CPUs, mobile CPUs, and embedded CPUs. But within each segment there are just too many choices that make it difficult to understand the whole picture without true data analysis like this article.
I don't understand how Core was an improvement on Pentium. Pentium was iconic and a household name (which is pretty difficult to achieve in such a low-level field, especially as Intel typically doesn't sell direct to consumers). Core is boring and misleading. For instance, Core 2 Duo ... whuh?! Doesn't sound that impressive but definitely sounds muddled.
Now there's this i7 and i5 business. Maybe I'm just old but I preferred when "Pentium n" is the new processor and probably better than my "Pentium n-1". I can understand they may have wanted to avoid the Sexium but at least that would be distinctive. Core is about as boring as traditional IBM naming.
Their hardware is excellent these days. They went through some doldrums but generally seemed to sort themselves out pretty effectively and come out with ace stuff. Their Linux support is usually great too. Maybe one of these will be my new PC...
These chips have some kind of AES acceleration, called AES-NI.
Are there any benchmarks of this? I use dm-crypt on Linux w/ AES-128 and the throughput is pretty low, about 60MB/sec tops, not as fast as the disk itself.
