Amd vs duo core 2

[Preti9cboi]

I'm reading this chart on anandtech and i think i am reading it wrong.
http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=2795&p=7

According to the chart it says lower is better and in both charts amd has lower numbers. But according to anandtech, intel uses less watts? What gives? How come the chart says lower is better but intel is better at watts per performance???

The two AMD chips that beat the C2D in load power consumption are the EE models, which are undervolted. Versus the standard voltage X2s, the C2Ds are clearly lower under load. You also have to consider the AMD chips are running on a micro-ATX motherboard M2NPV-VM, while the C2Ds are running on a high-end, dual GPU capable P5W-DH. Using a low-power platform like the 945P can save upwards of 30W in system power versus the 975X in idle and full load situations.

Uh, you need to reread that chart buddy. If you look at the power consumption numbers @ full load, the E6600 is the 3rd most miserly chip tested. The only AMD chips using less power are overpriced EE parts designed to run at lower stock vcore settings.

The E6600 is faster than any of the AMD chips testing in that lineup, too, which is quite something considering the fact that it outperforms every AMD chip tested and uses less power than all the AMD chips except two EE parts that can't hold a candle to the E6600 performance-wise.

OOOO okay thanks!

I think my mob died so i'm considering an upgrade. I generally like to buy things that produces less heat so it wont be as loud. Thanks though!

Since you guys are reading this, can one of you help me figure out what might have went wrong with my computer?

I went to eat for an hour and cameback and everything was black!!
Basically, there is no power to my DVD drives and my keyboard does not light up when i turn it on.
It's just pitch black on my monitor when i turn on my pc.
Fans and lights work fine inside the case but no heat is being generated at all.

Check error beeps/lights after your computer starts up (or fails to start) and compare them to your mobo manual.

It sounds very much to me like your motherboard has bit the dust, Preti. Of course, it could also be the psu. Whenever something along those lines happens, about the only way to find out what went wrong is to start putting parts into other, working machines.

 

[Preti9cboi]

Yeah, that's what i figured. You dont think it could be my CPU huh? I dont feel like taking that thing out. heh

 

[myocardia]

Personally, I would put the cpu third on the list. I would think it's almost certainly either the motherboard or the psu. If you have a digital multimeter, you can test the psu in about one minute.

If not, the only other way to test the parts is to put each into a known working machine. Also, you should definitely try unplugging (from the psu) all of your optical drives before you do anything else. Stranger things have happened in the computer world.

seeing as the lowest core 2 duo on there @ load is barely more power than the 4600+ , the idle power is probably because of the chipset. intel's desktop chipsets do not power down or go into sleep states like their mobile ones.

that said, a core 2 duo e6300 with 2mb less cache and a good amount less clock speed, could even be close to a 3800+ x2 EE. and those 3800+ x2 ee are cherry picked. at the normal voltages they probably would be 5000+s or something. and an e6300 is still mostly faster than a 4600+.

paired with say a mobile chipset or at least just a less power hungry one like a 965 of 945 i think the core 2 6300 would win even at load.

Could i pick up a cheap digital multimeter at home depot? How would i use one to determine if the PSU is working correctly? I'm guessing the instructions are easy to follow?

 

[myocardia]

Wal Mart has them for $20 or less. Fry's Electronics has them for $10. I've never looked at the ones they carry at Home Depot, although I can assure you they'll have some really nice, but expensive ones.

To do the test, just first unplug all of your optical drives, so you'll know it isn't going to boot with them out of the equation. Then, turn it on, and grab an unused molex connector, and put the red lead on either of the outside pins, and the black lead on the pin that's two away from it (next to the outside pin on the opposite side, in other words).

That will either give you your 5v reading, or your 12v reading. Then, do the same thing the opposite way, with the red lead on the opposite side. This will give you the other reading. Unfortunately, it isn't possible to test the 3.3v reading without removing some insulation on the 3.3v wire, or having something that can pierce it. Of course, that also requires knowing which wire is the 3.3v wire. But, the 5v and 12v rails are very easy to check, and are the problem, most of the time.

 

[Preti9cboi]

Thanks. When you say unplug all of my optical drives do you mean unplug everything and leave only my mobo connected? And i am guessing anytype of reading is a good reading or does it specifically have to jump to a known number as in 12 for 12v?

And you use the term 5v and 12v rails. Do those referr to the type of PSU or the specific wire i am testing? Thanks man you're awesome!
