P35 is 90nm - what the hell??

[Richard Dower]

Intel P35/ICH9 Specifications:

Chip Mfg Process Transistor Count TDP
P35 90 nm 45 Million 16W
ICH9 130 nm 4.6 Million 4W

:eek: what the hell man?...i thought Bearlake was 65nm?, no wonder it consumes more power the the nVidia 680i :mad:

Dammit Intel, move over to 65nm already!

[Knight]

At least it runs cooler. :shrug:

[Okda]

r u sure it is cooler ?

[Lu523]

Hmm. Makes me wonder what X38 will be.

[IluvIntel]

Where did you find that information Richard? I can't seem to find anything on Intel website about P35 or ICH9. Probabaly because NDA not lifted?

[NickS]

It runs cooler than 965, it's already been said.

[turtle]

NDA is lifted, it is 90nm, and it actually consumes quite a bit more power. According to anandtech, it uses more than the 680i:


"The surprise is that despite a 16W TDP, the P35 boards actually consume more power than the other chipsets at both idle and load. Even though the DDR3 board has a lower power rating for the memory, it consumes more power than the DDR2 board due to additional circuitry . We can no longer say that NVIDIA is the only high performance chipset approved by OPEC...

...Power consumption was a concern for us. Based on the current chipset TDP ratings we expected the power envelope to be near the P965 or possibly improved depending upon how aggressive Intel implemented power saving features on this chipset. Instead, we end up with a chipset that now consumes more power than the 680i and requires even more elaborate cooling. Something the motherboard companies have obviously taken to heart by the amount of heat pipes on the boards now. We doubt all of it is really needed but it is amusing for the time being to see the manufacturers trying to outdo each other in both design and amount of aluminum they can squeeze into a three inch square space."

I am guessing that it's 90nm because not all fabs have switched over yet to 65nm, and they are producing the lower priority item (chipsets compared to CPUs) in the older fabs. I imagine when we see Penryn the chipsets will be 65nm, at least for some period of time if a newer chipset comes out before Nehalem.

[IluvIntel]

NDA is lifted

You sure of that, no results come up in search of Intel website.

[dinos22]

i think NDA is lifted tomorrow or something

[turtle]

Well, Dailytech says so, and there's a whole mess of reviews launching today:

[rithina]

That anandtech link stated that p35 official support x8 dual lane if mobo manufacturer supports it.. but currently all p35 support 16/4 .. think it will come up with a bios to enable it later?

[dinos22]

NO

this is more than just a bios fix
they need to have different hardware to enable that.......it's a little more expensive but none of the manufacturers want to take it up :down:

they are banking on selling X38 to people with deep pockets and don't want P35 to compete i think

[ted3]

One more reason to wait for X38 then, hope it will be 65nm. Sold my backup 975X board at a bad price yesterday only to find out today that P35 is a old fashion 90nm chipset :( 10 watts more than 975X at 130nm, thats just crappy. But then again most Intel CPUs at 90nm was crap also.

[ziddey]

nothing wrong with 90nm for chipsets at this point in time. I don't know why people are complaining about keeping with 90nm. Die shrink doesn't always mean wonders. Remember first gen prescott anyone?

judging by the way the p35 can block to mid 500's with ease and topping 600 on more than one occasion, what's to complain? just load up a big heatsink / air cool and call it a day

[ted3]

Anyway it exlains the excessive heatpipes on P35 boards, they are really there for a reason. I cant get over how stupid the MSI looks with the rollercoaster heatpipes, but good to know they have a purpose.

Hmmmm...but P35's die size looks smaller than P965,they are both using the 90nm process
Anyone can tell me what is the P(G)965 and ICH8 spec? thanks

[OBR]

My P35 MSI Platinum has really cool heat-pipes ... but now i have Gigabyte P35-DQ6 and chipset blocks are hot like hell!

[Neon Biker]

That's just great! :mad: Everyone said the P35s were going to be cool runing 65nm chips and now it turns out they're even worse than nVidia's power hungry beasts. Man... and I was so looking forward to them... :(

[Atom]

After reading this,i feel like taking off my striker i put up for sale and just stick to it a little longer for the 65nm
Does it make any sense that way?I dont even know if my bill going to be crazy high anyway.I dont even leave my pc on 24/7 anymore because of the 8800gtx and the QX6700 consumption
so if i do get that board and do a mild oc to like 3ghz,would my bill electric bill skyrocket by like a $100 more or what?

[jacky89]

But Tomshardware shows that the p35 chipset uses alot less power than otherhttp://images.tomshardware.com/2007/05/21/intel_intros_3-series_chipsets_with_fsb1333_and_ddr3/image029.png chipsets

http://www.tomshardware.com/2007/05/21/intel_intros_3-series_chipsets_with_fsb1333_and_ddr3/page19.html

So who is to believe? Anandtech or Tomshardware?

Also anyone know what the difference between Asus p5k and p5k3?
Here is a great deal for the regular Asus p5k. (http://www.excaliberpc.com/Asus_P5K_Motherboard_LGA775_Intel/P5K/partinfo-id-579376.html)

[Rickster_64]

Read the Anand article. They used DDR3 which used several watts more than the same speed DDR2. That is where the power comsumption differences come in. Tom's used DDR2-800 which is what you and I will be using for a while and you see the true consumption numbers. I believe they showed a page either on Tom's or Anands on the difference of power draw for the memory alone.

If everyone is complaining about an extra 10W from the motherboard they better never upgrade to an ATI 2900XT :rofl:.

The Tomshardware power consumption results look more accurate as to what DDR2 users will experience. Anandtech was testing with DDR3.

The regular P5k is just the vanilla version without the Deluxe features. The P5K3 Deluxe is the high-end DDR3 board. It's the same as the P5k Deluxe in design.

[turtle]

P5K is DDR2.
P5K Deluxe is DDR2
P5K3 Deluxe is DDR3.

Both deluxes are on the anandtech graph, and both show to use more power.

Granted, deluxe boards probably use more power because of the RAID controlller, Wifi, extra USB/SATA ports and VRM, but even the stripped down boards seem to be fairly hefty in power usage overall.

Who knows which board Tom's is using in that test, but Anand prolly tested at 1333 FSB where-as Tom tested at 800. Voltages are unknown AFAIK for both.

All these things cause variations in the results.

[ziddey]

I don't know why everyone is so bent that it still uses 90nm or more power. Does it not clock better than the p965? Are memory dividers more functional in upper fsb's? Is pricing for the lower line like the p5k vanilla not decent for a launch price?

[Richard Dower]

It's moving forward Ziddey...more advanced manufacturing process.

[ziddey]

I don't know if I'd call that necessarily moving forward. Like I mentioned before, I'd take a northwood c over a first gen prescott any day of the week.

[Richard Dower]

65nm should equal, less power consumption, less heat, less leakage etc....add to that it's quite possible more voltage could be run through it for a higher O/C.

[WRC]

regardless these boards are great, it is also less bug free than when the p965 first came out and is priced similar with much better performance, so far there's nothing to complain about it's a win/win situation for us consumers

[JuanFlaiter]

AFAIK Bearlake is 65nm, at least that´s what Intel told me. Maybe Anandtech made a typo? I´ll double check.

[jacky89]

P5K is DDR2.
P5K Deluxe is DDR2
P5K3 Deluxe is DDR3.

Do the p35 chipset allow you to set the strap to 800, 1066, and 1333 without having to do the conductive ink mod? If that is the case, then what's the point of the E6x50 chips if we can just set the strap easily with the p35 chipset?

[OBR]

Firsta revision of P35 are 90nm, second will be 65nm ... i hope second will be on market soon!

[Neon Biker]

Where did you hear that? Anyway, I can't wait God knows how long for God knows what revision. I have to buy something now. It's funny though, a lot of people are saying the new boards are runing cooler, even X-bit labs said the same about P35-DS3R.

[mrcape]

If these guys make a new revision with 65 nm will they replace my rev 1 board? I know Evga was doing it, how is Asus in this regard?

[RealTelstar]

I'm pretty sure DFI will use the second revision p35 like they did with the 965 :)

[jacky89]

Asus website claims the following:
"The P35 is manufactured at 65nm, so it should require less power, generate less heat, and be more economical to produce than current chipsets."
