Intel announces energy-efficient quad-core processors that consume 50-watts of power
Intel today released two new energy-efficient quad-core Xeon processors for multi-processor servers. The new
Intel Xeon L5320 and L5310
operate at 1.86 GHz and 1.60 GHz respectively. Energy-efficient Xeon models consume 50-watts of power, which translates to 12.5-watts of power per core. Intel’s
regular quad-core Xeon 5300-series
consume 120-watts of power.
Energy-efficient Intel Xeon L5320 and L5310 processors are nearly identical to their higher-clocked counter parts. The energy-efficient models have 8MB of total L2 cache, 4MB of shared L2 per pair of cores, as with other Xeon 5300-series models. Front-side bus of the Xeon L5320 and L5310 are clocked at 1066 MHz, similar to the normal Xeon E5320 and E5310.
Pricing for the energy-efficient Intel Xeon L5320 and L5310 is $519 and $455 in quantities of 1,000, respectively. Intel Xeon L5320 and L5310 processors are drop-in compatible with Intel’s

RE: Single Core, Dual Core, Quad Core?

Well thanks, I actually wrote something a little bit longer (though I thought it was too long and trimmed it) talking about quad core performance in servers being very good even if they decided to serve off xp pro. It certainly couldn't match some specialized server software, linux, or even 2003 server it was no slouch. I've even seen dual quads serving off an xp pro box and get perfectly scaled performance along each added core. My point was quads are more a specialized task cpu (by that I mean you get it for a specific purpose, most likely in a professional/business/design/server environment) and unless you are running a certain program designed for a quad setup in that specific type of environment you won't notice a difference. And 99% of your home users will never use those programs.
The major problem with XP is the thread handler not allocating properly or efficiently. It's performance when you using dual core improves immensely (not perfect though and eventually reaches it's limits). One would expect that doubling to a quad core would have similar effects but it's improvements are very small. Now this is multitasking performance with XP allocating the cpu cycles for each thread. When you run a single program properly designed for quad you will get the performance you should. So like I said you can't assume anything other than XP on it's own isn't an adequate platform for quads, especially your standard home desktop user who thinks it may improve multitasking or.....gaming.
And if someone goes out and buys an $800-900+ quad for gaming they need to do some research or discover the meaning of priorities. For the same price or less you could get an e6600 and 8800gtx, or 2 8800gtx's for sli, or one of Dell's 24" HD lcds with either card or cpu etc etc. Several ways to better spend that money for an increased gaming experience that a quad won't give you.
