Intel Lindenhurst Xeon DP Platform Discussion
Steve from Hexus writes "Hexus.net has a article looking at Intel's latest Xeon platform: Lindenhurst, discussing the Paxville dual-core processor, E7520 core-logic, where it could go right for Intel, and where it could all go wrong." From the article: "If you're I/O bound by your threads in any way, you can hit problems (all threads touch the MCH, then there's a 266MiB/sec bus link to the I/O processors to cross, then the data hits disks or network hardware). If you're memory subsystem bound in any way, especially on a majority of compute threads, performance is likely gone. There's just too much resource sharing for it to all conceivably work well, especially compared to Opteron. I can forsee many a scenario where dual-core Opteron will give Paxville Xeon DP a beating."
there's a 266MiB/sec bus link
Wow - that's a *LOT* of Tommy Lee Joneses and Will Smiths!
Lindenhurst? They ARE running out of names. I spent a couple months in Lindenhurst, Illinois when I was about 1. It's a sprawl-barf located just outside the doors of Six Flags.
Yep, I'd say that if both her input and her output are busy, she's DP.*
*See, kids? This is why you should avoid too much pr0n, it just totally warps your mind.
Are you...Are you some kind of genius?
No, ma'am, I'm just a regular Slashdot reader.
What's next, DVDA?!!!
Hehehe.. type that into Google and hit "I'm feeling Lucky". Good for a laugh. Almost as funny as the National Association of Marlon Brando Look Alikes (or even funnier, as it's real.)
Where it could go right It's not all doom and gloom, though. Think of a scenario where compute threads rarely touch system memory , doing most of their work on the CPU with small working sets and you've got yourself something that Xeon should do well at. While those compute threads would have to be HyperThreading friendly to have HT be a performance win, Intel has spent good time making sure HT gets focus by application developers. If you read the last benchmark results for the dual core xeon's here you can see that AMD totally whipped the cpu into submission.
Yet Hexus.net still thinks they can find a task that the dual core xeon is better at, but yet they provide no real world example or benchmark results, so I guess they are still looking, perhaps they can find the right benchmark in the basement, or perhaps in deepest darkest africa.

It's also a lot of pugs barking to "Who let the dogs out?"
*shudder*
