Let's get a review!

Whoa, funky chassis design. Take a look at the back...

Yes, it looks like a carefully noise/thermal optimized design. The only downside: It's a 775 socket design. So far, we have only been able to find Prescotts, and they start at close to 90W max power.

A sample is on its way. Look for the review in 2/3 weeks.

It's actually not a downside that the SB86i is a socket 775. I wouldn't even consider a socket 478 (that's old technology.) If you still think 478 is better than you're living in the past. With socket 775 you also get the new, better chipset, better on-board graphics, better on-board audio (better than older 865 chipset XPCs) and PCI-express.

If you're worried about the thermal/heat issues make sure that you go with a socket 775 J processor, the new E0 steppings on them have fixed alot of the heat issues with prescott. For example, a Northwood 3.4 is 89W, where the Prescott 3.4J is 84W...

THE ONLY WAY YOU'LL FIND A NORTHWOOD on SOCKET 775 P4 is with the EXTREME EDITION CPU's.

Here are some comparisons:
Prescott (E0 stepping, socket 775)____vs._____Northwood (socket 478)
P4 - 520J 2.8 GHz = 84W____________________________2.8 GHz = 70W
P4 - 530J 3.0 GHz = 84W____________________________3.0 GHz = 82W
P4 - 540J 3.2 GHz = 84W____________________________3.2 GHz = 82W
P4 - 550J 3.4 GHz = 84W____________________________3.4 GHz = 89W
P4 - 560J 3.6 GHZ = 115W____________________________n/a
P4 - 570J 3.8 GHz = 115W____________________________n/a
(these numbers came from the intel website http://processorfinder.intel.com

While the fastest prescott's 3.6 and 3.8 would get pretty hot, those speeds don't exist with Northwood.

If you look at prescott and Northwood in the 3.0 to 3.4 GHz range, they are similar.

The sweetspot for Prescott where it would not be as hot as Northwood is the 3.4GHz
The sweetspot for Northwood is 2.8GHz.

Northwood is now only an advantage at 2.8 GHz and below.

(MikeC, when you do your review, use a J processor with the E0 stepping.)

MikeC, thanks for the link.

That list was last updated 25th June 2004, so I doubt that it includes the new J processors with the E0 stepping.

I'd like to see their Intel Processor Power Consumption specs for the new steppings.

Other advantages to the socket 775 P4's are SSE3, Execute Disable Bit, Enhanced Halt Mode and Thermal Monitoring 2.

The basic approach they take is to seek out the maximum current the CPU is rated for, then multiply by the Vcore. You will find it is signficantly higher than Intel's TDP, which is an approximation of what they believe will be the maximum load with a real life application. However, AMD takes the opposite approach: Their TDP for A64s is the maximum power dissipation possible. So to compare apples to apples, it make sense to use the MP for both Intel and AMD processors.

I agree with you on most points regarding the superiority of the 775 over the 478, particularly the integrated VGA, which is still not as good as offerings from nVidia or ATI. However, there is no need for any >100W desktop CPUs. That's silly, IMO. For a silent PC, it's just not a smart choice. Not when equivalent or more powerful Pentium M and A64 939 Winchester core processors at less than half the power are available.

you can get lga 775 Celeron D's so you aren't just limitted to hot P4's

Didn't you actually mean to say "you can get hot lga 775 Celeron D's so you aren't just limitted to hot P4's"?

GrahamGarside · Post by **GrahamGarside** » Mon Jan 10, 2005 8:22 am

the celeron d's only run in the 40's even with a stock cooler, granted this is at 2.4ghz but if you want a quiet pc then you are gonna go for the slower chips
I believe the lga 775 celerons start at 2.66ghz and this is with 1/4 the L2 cache enabled

Well, even 3 GHz Prescott runs in 40s... when idle. Also, the stock HSF is loud, even when the CPU is idle.

Let's just say that Celeron D is the least-hot CPU for S775.

Cheers,

Is this box actually available? It was supposed to come out in Q4 last year, but so far I haven't seen it anywhere. Anybody knows what's going on?

Here's the first review of this machine that I've seen:

Clubic review - in French!

Unless you parlez francais you'll need to use your favourite translator.

Somewhat unsurprisingly, the system gets very hot indeed due to the Prescott P4 and they indicate the system becomes rather loud, too.

GrahamGarside · Post by **GrahamGarside** » Wed Jan 12, 2005 9:07 pm

I actually meant at full load running f@h 24/7

the stock cooler isn't that loud really, it's by no means suitable for quiet cooling and I don't use it, but I've a friend who upgraded a K7 slot a and he was really pleased with the differance in noise
