Intel's D Series CPU's

Has anyone here tested the benefits or performance of the D 800's to the newer D 900's?

I have a D820 in my current DAW and was wondering if the upgrade to a D940 would be substantial enough to justify the cost?

Pro's & Cons?

Thanks!

I have the d830 and when I inquired about the d930 I was told it woul not be a very large jump in performance. It really depends on what you're doing but for me, an audio only guy with not very processing hungry material, it is more than enough.

here is the pricechart for the next month so you can see yourself what the best time for buying a new cpu is. Id buy close after or when the price actually changes.


and then here is a CPU benchmark chart tool (its on german, but Im pretty sure youll get along, and if not.. there should be an english one out there on the net!)

good luck!


benefits I know are, that the 900 series doesnt get as hot (temperature wise) as the 800 series. wich results in lower fan speeds and less noise. Conroe is to be expected a lot colder. Im waiting for one of those or at least a conroe-compatible mainboard to upgrade later.

Dual core or dual cpu will give better response time.
Not sure about pro tools but nuendo likes dual cpu's

DAW performance is complicated. Everyone thinks a fast cpu is going to be the
magic bullet. It very well may be for some folks.

In most cases hard drive speed it the bottleneck. With todays cpu hungry FX
a fast CPU is needed for sure. But hard drive is still the most important thing
when dealing with large amount of tracks.

The one thing that can increase any DAW performance by 50% is a busmaster scsi
setup. SCSI are still the fastest hard drives. If you look at all these pretty charts
you may see serial ata within 90% of a SCSI. But most of these tests are reading and writing buffers in 'burst' mode. For us DAW guys these tests are worthless. We are reading and writing 10 to 100 files at a time.

this is were busmastering comes in handy. A bus master card has a CPU on it dedicated to reading and writing to your hard drives. It relieves your computers cpu from literally millions of instructions.

I would rather have a 2gig cpu with an ultra scsi setup than a 3 gig cpu with
a cheezy SATA drive. Also folks who have 2 - 4 gig of ram in your PC you wasted your money. Unless your loading a 2 gig sample loads of memeory is pointless.


So inother words there are other factors in DAW performance besides main CPU speed

dont get me wrong..

he has already dual core and wants to upgrade (830 is dual core...)

I think SATA is fine for audio. If you have an "okay" controller you can run 2 fast SATA drives in raid 0. it may sound a bit harsh, but Scsi is dead in my eyes. Scsi is a really nice thing, if it runs trouble free... it gets off the cpu, but we have 2006.

Audio is pretty small bandwith
100 tracks * (41 khz) * (24 bit) = 11.7301941 MBps (only!) [of course you might have other operations and tasks on HD going on, but thats why you should have seperate disks for audio..)

if your into video, case is a totally different one. but SATA is taking over here too... (it just depends on the controller and the drive)

all the trouble that poeple have with HDD are usually caused by bad drivers and chipsets (controllers).. then they blame SATA or EIDE, its the old story of buying something cheap and getting what you pay for.

I really appreciate the comments here. Wow, thanks for the chart!heh

Right now I'm knee deep in Hip-Hop arranging for a new artist so my computer is tied up with more soft synths than audio tracks at the moment. It seems that I'm just short of being able to get the basic tracks done without "bouncing to tracks" my soft synths. If I can keep from doing that my work flow improves.

What kind of improvements do you feel we will see with the Conroe over the D series besides cooling?

I guess you have no concept of buss mastering
that's OK

@allencollins...
I didnt mean to offend you.
are you talking about putting 16 stereo busses DA out into a dang.bus/analog console (or whatever) and then getting 2 AD back?
I dont do it personally (dont have the money for it.) we do it at my cousins though, its only 24 mono to analog console though... so maybe not the bandwidth a real professional uses. we do that with EIDE (!) and some old athlon xp... works fine though.
are you talking about 2track mastering? Im sorry... explain it to me please.
if youre talking about mastering itself.. i only now theory about that. feel free to teach me.

something more about scsi, cpu usage etc... it was hard to find something on english..:
http://www.pugetsystems.com/articles.php?id=19 [from 2005]

about Why it is the way it is.. you should read the article. scsi is fine and works great (its really cool for database search operations!)... ...just read the article it isnt very technical though...


about conroe...
http://www.hothardware.com/viewartic...?articleid=794
intel did a benchmark that - from public side - got heavy critique, cause they did the benchmark all alone, with a conroe (that wasnt out on the market) against a OCed opteron system that has been setup by them...
all in all... later on poeple build up and OCed the opteron system by themselves and drove the benchmarks again (with up to date bios and some other things tuned that they thought might be the flaw in the benchmark)... the opteron rated better, but still not as good as the conroe.
intel finally seems to get into the position to compete with AMD in terms of cpu power and heat (wich is more important than ever) again. I dont have a too good opinion on the 800 series. [we OCed a 805 from 2.66 to 3.8ghz stable... but the system now sucks 500watts.. and its loud. its not designed to be a audio machine... we think its actually going to die as soon as the resistors give up...]

AM2 series isnt really attractive (its not really a step up from S939), cause Intel is drowning prices right now (see the chart earlier... ) and in the next month to promote and invade market with its new "label" "Core Duo" / conroe... [Opteron is also a nice system to consider...]

it just depends. if you need more cpu power NOW. then buy as soon/late as you need it. if you can wait a little longer. get conroe (but youre going to need at least new Motherboard, maybe new ram, etc ,etc..) Conroe isnt compatible to older boards although its on basicly the same socket.

for the most part:

faster processor will get you more plugins.

more processors will get your more plugins. it might be better for you to get a dual processor motherboard and get another D820.. <drool> 4 cores </drool>

getting a raid setup or even a scsi setup will get you more tracks at once..

more ram will not to much other than run more spyware at that same time or load more porn into photoshop..

Hello,

The 900 series with 2MB cache per core will help you when working at latencies below 256 buffers or 6ms.

In adition, they run cooler than the 800s.

Dual Core will run more plug-ins and VST instruments when used with a DAW that can use 2 or more processors ( Cubase, Nuendo, SONAR ).

Regarding hard drives, one SATA drive with 16MB cache will do very well even when running 100 tracks.

Regards,

Dude you have way to much time on your hands. Don't you kids work after school??
I knew you wouldn't understand busmastering. Put down the PC World Magazine
and take a hardware class at your local comminty college or something.

I take it youve never produced a large scale project. SATA is fine for small projects

Also you may want to call Adaptec, Qlogic, Seagate, Futijsu, IBM and Silicon Graphics.
Tell them you think SCSI is not worthy. This way they can close down their Billion Dollar
SCSI FAB clean rooms and focus on SATA Technology.

Man your in the wrong field. You should be a High Tech Blue Chip CEO or Executive strategist
Man I respect the **** out of you!!!! really!!!!


cool

okay. this might be a language barrier.. this is what I meant. scsi is great for huge projects. i simply dont consider audio as really bus intensiv. there are no big databases, huge datastructure where a scsi drive can really play out its capabilities.
if you read the comments of the article, theres also said scsi really starts to play out when you start using more than one or two HDDs [this means in servers, audio computers are no servers].

I dont read PC World Mag (whatever that is..) and already go to university for CS so I dont really see the point looking for a community college, but thanks for the advice.

you can send me a pm if you want to discuss this further. it doesnt really help the original question. if im ever in boston ill buy you a drink man.
