Intel's Pentium 4 E: Prescott Arrives with Luggage

SYSmark 2004 Overall
The entire sysmark run including all the individual tests we will be reporting took anwhere between two and three hours to run. The two main suites (Internet Content Creation and Office Productivity) each took up half of the time (in contrast to Winstone where the business benchmark completes much faster than content creation).
The overall score which takes a little of everything into account shows the Gallatin based Extreme Edition coming out on top in both of its flavors followed by the fastest Prescott.
This is the first time we've run Sysmark in our labs, and we weren't sure what to expect from this highly visible test suite. We can say that the numbers we see here an in the following graphs don't tend to reflect what we see though out the rest of our testing.
We included these numbers for completions' sake but we are not going to draw any conclusions based on the benchmark as we have not had much experience with it. We do know that this time around AMD did have equal input into the creation of the benchmark, although it does still seem to favor Intel's architectures.

Hmmm... on Intel's website on the new processor news: "Thermal Monitoring: Allows motherboards to be cost-effectively designed to expected application power usages rather than theoretical maximums."Not sure what it means. I'm thinking clock throttling so that if your particular chip is hotter than it should be it will run on under engineered motherboards/coolers.
This chip dissipates around the same heat as Northwoods clock for clock! And of course, Intel style is wait 6-12, then the new stuff will actually be good. Still, is it really that important to increase performance so much that heat becomes an issue? I.E., will Dell be able to make the cooling whisper quiet? They can with the processor sitting at 80-90c, but now that with normal cooling it's almost there, now what will they do? Why can't we just have new processors that run so cool that we can just use heatsinks without fans? Oh well.

Great article :) I found it very interesting I dont think I'll be buying a prescott till they hit about 4Ghz. My 2.4C is nice and fast for now.CRAMITPAL - Monday, February 2, 2004 - link

To Vanners, #38:"if you halve the time for a stage in the pipeline and double the number of stages. Yes this means you can run at 2GHz instead of 1GHz but the reality is you're still taking 5ns to complete the pipe."
Yes and no... In the example, you're right that a single instruction takes the same 5ns to complete. But you're not just executing a single instruction... rather, thousands to millions! The 10 stage pipe has twice as many instructions in flight as the 5 stage pipe. Therefore in the example, you get one result out of the 5-stage/1Ghz cpu every 1ns, but TWO results out of the 10-stage/2Ghz cpu in the same 1ns... twice as many.
What I find interesting is that as pipelines get longer and longer, we might have to start talking about Instruction Latency: the number of clocks and ns between the time an instruction goes in and when the result comes out. It'll never be anything a human could notice directly, but it might come into play in high-performance realtime apps that deal with input from the outside world, and have to produce synchronized output. Any CPU calculates somewhat "back-in-time" as instructions fly down the pipe... right now, a Prescott calculates about twice as far behind 'reality' as an A64 does. I don't know if there is any realworld application where this really could make a difference, or if there ever will be, but it's interesting to ponder, particularly if the pipeline lengths of Intel vs. AMD continue to diverge.

i don't see how a 4+GHz prescott will match up with intel's new pico BTX form factor...with that much heat (using air cooling), you need to keep a safe zone around the proc unless you like your RAM DDR+BBQ.I'd have to say that a lot of enthusiasts are younger and live in limited space conditions...might work well for people up north who don't want to run the heater, but as for me in texas, i have all the cool air pumping in to my bedroom and it still takes a lot to keep it cool. Can you imagine a university or corporation having a room full of those?..if they think about that, then it's no bueno for DELL and others as well.
I'd also have to agree with the others about the heat/power being a major part of the article that was left out...otherwise a tremendous read, thanks for all the effort that goes into these.

But - I need to add - the correction was needed and is welcome. Not trying to pick a bone with the editors.tfranzese - Monday, February 2, 2004 - link
#55, you read what I read. I'll vouch for you.Icewind - Monday, February 2, 2004 - link

Is it just me (who was extremely tired yesterday) or has the 101 on pipeline part changed since the article was put up?I seem to rememeber reading someting about how a 5 staged CPU at 1 Ghz should be exactly as fast as a 2 GHz CPU with 10 stages (all else being equal of course) and that the secret of geting any profit out of going to more stages was to make sure that it couldn't only scale to 2 Ghz but to 3 Ghz or more.

I think shuttle owners are SOL with prescott.
