Re: dual 1 GHz CPU's

Joe,

I think you're missing what Scumbria is saying. He's not talking about "dual CPU's" in the traditional sense. He's talking about 2 CPU's (or more) on ONE chip.

Here's a interesting read to help explain:

chips.ibm.com

In one configuration described in the article, four POWER4 chips, each with two central processing units, are placed on a single module that's small enough to fit in the palm of your hand. The microprocessor has two 1 GHz cores and 100 Gbytes/sec. of internal bandwidth, enough to transport up more than 20 full-length movies in one second

The comments about Itanic quite interesting. They describe the poor support Itanic will have for Java, but say this will all depend on how big java gets in the next few years. This is clearly not what IBM believes. In a recent seminar I went to, the speaker took a poll at the beginning about what everyone thought the dominant OS would be in a few years. We all guessed Windows, Linux, etc. Then the speaker said he sees a future where it doesn't matter because everything will be java. If true, the lack of java support will cripple the performance of the Itanic.

Does anyone know how Sledgehammer is planning to deal with java? (you can read the article to see there's different ways of going about it)

After reading this article, I can see why IBM has hedged their bets and is still going full force will the POWER design. I'm starting to side with Jim about how Merced will be the worst processor mistake in history.

Joe,

Most benchmarks (Anand did some about a year ago) show hardly any improvement of dual CPU systems over single CPU systems

Unless the application is multi-threaded, Windows can not take advantage of the parallelism. The advent of CMP processors will spawn a new generation of software.

AMD is right on the mark with this.
