I'm doing another round of hardware evaluations. I'm looking at a Compaq N620c laptop with a Banias based Pentium M processor. It's a 1.4 GHz CPU with a 1MB L2 cache. Battery life is excellent, but not while crunching, what else is new.

So far, I've only had a couple of high AR WU's, but they've completed in 1:51. Processor efficiency is 2.7x CpF. That's better than an Alpha with an 8MB cache! If I get time, I'll run the benchie. I wonder how quick a 1.6 GHZ Pentium M will crunch? :drool:

Wow 1:51, that's awesome. What's a Pentium M, Greg M? Is that a PIII or P4 based? Maybe I'll sell my current laptop and get one of these.

Greg M · Apr 14, 2003

It's the latest mobile processor from Intel. Its codename was Banias and is now part of the "Centrino" chip suite Intel is marketing.

TC · Apr 15, 2003

Pentium M is sorta like a P3 with some of the P4 bandwidth enhancements. Really what they should have made the P4 to begin with.

Greg M · Apr 15, 2003

At 62% completion, I'm seeing CpF of 1.60. Yowza!

Good lord, that's pretty impressive!

i've been thinking of it, and trying to talk my GF into selling her SONY Athlon4 1GHz laptop for a 1.4-1.6GHz PentiumM laptop. and she does like the new SONY Centrino laptop too.....well, we'll see.....

markodude · Apr 15, 2003

I have one of these chips sitting here (1.4ghz Pentium M), but nothing to test it in, getting a board that is usable outside a laptop is proving impossible! THis would be a nice chip in a desktop as well....

No, it doesnt work in any existing desktop boards, even with pin modification to allow it to fit it is not compatible with P4

JigPu · Apr 15, 2003

Any word on wether Intel is porting it to the Desktop?? :drool:

As soon as I went and read through the Intel forum trying to figure out exactly what this 'Centrino' stuff being advirtised on TV was, I knew I wanted it as a SETI cruncher.

... If only I knew it was THIS good! Benchmark the thing Greg!!!!

centrino won't be offered on desktops - it's designed for laptops to maximize their batteries.

Greg M · Apr 15, 2003

Intel would be stupid not to adopt this core to the desktop.
(So don't expect it

)

For lower AR WU's, CPU efficiency improves to the 1.2x CpF range. It did a .389 in 2:38 and the current .410 was 2:29.

Work and RL are an absolute biotch right now. Will bench if I get the time.

For the record, "Centrino" is a suite including the Banias based Pentium M, chipset, and wireless chipset. The processor alone is a Pentium M, not to be confused with the P III-M or P 4-M. Clear as mud?

I'm with jigpu!!! I want this technology for desktops!!!! IMAGINE

Greg M · Apr 17, 2003

I want it in multi-processor servers!

wow, that's the time of a good memory 3GHz P4 speed!!

everywhere i seen, a 1.6G P-M (1MB L2) is about or a bit faster than a 2.4G P4. but guess it proved again SETI LOVE bandwidth & L2 cache!!!

now show me the Prescott please................(1MB L2 of a Northwood core plus other tweak) or the next gen. of Banis, Dothan(?), that will have up to 2MB L2..... :drool:

Xtc4u · Apr 17, 2003

and how much do these laptops normally run? $$$

When are these coming out? Seems like SETI loves big cache. I'm really thinking about replacing my laptop, maybe I'll til one of these make it mobile.

Greg M · Apr 17, 2003

Dothan will slide into the Pentium M role. It will be Intel's first CPU built on the .09 micron (90 nanometer) process.

I get corporate volume negotiated pricing, so I don't know what they go for on the street. The retail price of the one I'm referring to is $1799.

Dell is offering an Inspiron 600m with Pentium M starting at $1099 after $100 instant rebate and $150 mail in rebate.

LandShark · Apr 17, 2003

i've seen typical street price from close to 2 grand Toshiba to mid-2 grands SONY, IBM, etc....

that Dell IS really good price; however, it's too bare minimal for my taste (or today's standard). no 15" screen, no dvd/cdr combo drive.... yeah, you can config. it, but than it all add up....

funny to notice the other 2 model at the right? ONLY 128MB memory for the WinXP!!

Yodums · Apr 17, 2003

That's awsome. Submit a benchmark

Greg M · Apr 19, 2003

I'm too busy using it during what should be my sleep time to keep up with the goings on here. I don't get 4 day weekends like the eager beaver.
