Multi Core Processors & Power Requirements

Hello I'm considering upgrading an aging computer system and was looking at dual and quad core processors. The AMD dual core is rated at 65 watts is that for both cores or for just one, I guess the question I'm asking is is the wattage that listed for the entire processor or just one individual core.
May sound like a silly question but I really wasen't sure. Thanks

Power ratings are always for the entire unit no matter what it is....

Say thanks so for the quad that's rated at I think 95 that's for the entire CPU? Just wondering why I've been reading so much about people complaining about the power required for these processors that's really why I asked even 95 watts really isn't all that bad just like a light bulb.

Yes, that means the TDP rating for the WHOLE CPU is just 95 watts

What you need to do is go to your motherboard manufactures website, lookup your mobo, and check the Supported CPU list. Just because the socket and TDP match, doesn't mean the bios will work for a new chip on an old board. If you can't find the list, post your board and we'll see if we can find it.

Hi thanks good advise the board I currently have in mind is the ASUS M4A785TD-V EVO AM3 I was thinking about coupling that one with possibly a AMD Athlon II X2 250 Regor 3.0GHz.

Thanks guys for all the help! I was considering a quad processor but I read that in order to really take full advantage of these multi core processors the software has to be written specifically for multi thread applications, and that single thread programs are unable to utilize the processing power of the second core, and therefore will see no appreciable increase in performance. I do plan on eventually doing some video editing and I understand these programs are specifically written to take advantage of the second core so I will eventually gain some benefit.

ANY video editing will take advantage of extra cores, perhaps look at the athlon tri or quad cores

A dual will gain benefit for the basic user anyway because there's always more than just 1 app running. Virus scanners, operating system services. If you plan to keep this system for a long time also, I'd spend the extra few bucks to get at least a tri core or a quad if you can swing it. In the long run, it will really pay off and you'll get more benefit from it than you think.

What would you recommend this board gives me a pretty good upgrade path, didn't want to spend more then say 150 on the processor less if possible.

Athlon II x4 630 is only $100
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I think its worth the $4 for the extra 200mhz speed over the 620.

If you're not overclocking and not doing professional grade editing, no need to spend the full $150 on a 945 or $160 for the 955.

+1 to what skora said.

I use that processor on my rig and it's very fast for the price. Can't go wrong really :)  Also as single core CPUs are fading out rapidly, more and more applications will be written to take advantage of multiple CPU cores. The Althon II X4 should mean you don't have to upgrade for a good few years!

Hi what increase in speed would you think I might see going from a dual to a quad processor running multi-thread applications there's twice the number of cores but I wouldn't imagine it would be as simple as twice the processing power, and do you think 95 watts is reasonable for a quad processor. This is one of the best sites I've come across everyone is so friendly and helpful, loads of help here I highly recommend it!

We are all glad to help.

Here's a fun way to illustrate the difference. The blue line is the Athlon II 630 x4 2.8ghz. The orange line is the Athlon II 240e x2 2.8ghz.

http://www.anandtech.com/bench/default.aspx?p=105&p2=11...

On the multi threaded apps, the x4 is vastly SUPERIOR. The single threaded, they are generally pretty close trading wins, but nothing that buries the other. The other advantage for the quad is the benchmark system is going to be running a very clean OS to isolate how the CPU effects the program performance. So a virus scanner isn't running, all the programs looking for auto updates, downloads, web browsers open, all that isn't running for the test. In the real world, all these resource thieves will be running so the quad core will do better than the benchmarks show compared to the dual that has 2 less cores to share for those other tasks.

My take on this is, you have upto $150 for a CPU. Minimum, you need $58 for a CPU. You could justify a CPU upgrade within 2 years and have to shell out more then if you want or just let the system do its best and live with it. Or, spend $100, far less than the cap, for a quad core, and have a CPU that will run for much longer than dual before showing its age. The cost ratio to expected life easily justifies the extra $42 now and as more and more apps go multi threaded, you'll be prepared for them.

As for the TDP or wattage of the CPU, that's a stat that represents the most amount of current the CPU is designed to handle. The current generates heat, so the lower the better. 95w is very reasonable, but really, that number shouldn't be anything you're using to make a decision unless you're looking for extreme power savings. Performance wise, doesn't matter.

Thanks! I agree think I'll go with the quad, now and with this board I still have a decent upgrade path. I actually started this project a few months ago and at that time I got a good deal with rebate on a 500 watt Thermaltake power supply hoping that will be sufficient, plan on two hard drives a DVD and CD drive sound card, and that quad core processor. You think that's sufficient hope so seeing that I already bought it.

Yeah, 500w will be more than enough for that setup. Here's a calc if you want to see how little you'll actually use. For that PSU, you'll want to load it no more than 60% of capacity, but I'd be surprised if you top 200w. Do you do any gaming?

What resolution monitor do you have? That is the biggest factor in how inexpensive of a card you can get away with. The onboard graphics on the mobo probably won't be able to do much in the way of first person shooters, might be able to do some rts on minimum settings if the resolution is low enough.

When you do play, are you okay with less than max settings for the visuals?

for 100$ go with a 5670, if you can squeeze a little more go with 5750 or 5770. The 5670 will be good for playing medium-high settings at 1080p

Thanks again guys I checked and my new power supply does have a 6 pin connector kind of did my homework on the power supply extensively before I made the purchase and was trying to be as forward thinking as I could be, so that it wouldn't be obsolete the day after I made the purchase only thing I'm missing is that new PCI express 2 connector I just have 1 PCI express x1 connector. Going to look at these cards and get back.

Guys, Guys REALLY SORRY guess I got confused it's been a while since I upgraded and things really change fast in the computer world, and I guess I'll have to get a subscription to one of the computer mags again to keep up! Concerning the PCI connector, what it actually said was that it has that new PCI EXPRESS connector and my original question was don't they also now have a PCI express 2, and what are these basically used for? Sound cards I'm just not sure and trying to catch up. Thanks!

On the motherboard, PCI Express slot uses the same physical slot as PCI Express 2.0. The cards are backward compatible and can use either. The PCI Express 1.0 is good enough that it won't effect the 5770s performance.

The power connector will be a 3x2 pin PCI Express connector. Looks like this, you'll need just one for a 5770:

Hi I have that connector Thanks and just saw that card on Zoomfly they now have it for 150!! but Newegg has it for 119.00 after rebate think I'm going to try to snap this one up seem like the general consensus is that this is n excellent card if you read the reviews, I especially like the Crossfire support!! just a little more checking before I order.

When do you need this? Nvidia will release their high end GPUs on the 26th and it will take a few months for the rest of the line to roll out. But when it does, I'm sure we'll see some more price slashing like that of the 4850 being driven down under $100 early on.

Just took a quick peak, didn't see any stealer deals on the 5770 front.

I wasn't suggesting a 4850, but we'll see prices on the 57xxs drop much like the 48xxs did to compete with the GTX 2xxs. If he can wait for that, then a 5770 1gb might be regular price back in the $125 range or Nvidia playing catch up offer similar or better performance for the same price. My crystal ball is broken at the moment.

Hi I just saw it $150 hmm..... just a little more then I wanted to spend bu I'm still considering it. Say what about this cheaper alternative. Also whata' think about this AMD Callisto Black dual core processor, and how do you think it compares to this quad see below, they both cost the same but I understand (heard) the dual core is better.

That first link is broken. Took some cut and paste to find out its the GT220. At 1920x1080, it will be severely lacking in performance. Lowest I'd suggest is the 4850. This one is $85 with the promo code if you order it today.
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Otherwise, that 5770 linked is $133 amir.

For the CPUs, you have the 555 linked twice. I'm guessing you're asking about the 630 v 555be? Which is better really depends on what you're using your computer for. Here's the stock speed head to head:
http://www.anandtech.com/bench/default.aspx?p=105&p2=12...

They both have big wins. The 555 in all the games except Dragon Age Origins and the 630 in anything that uses the extra cores. That's a decision only you can make. If you OC both, the 630 will close the gap on a lot of the 555 wins and extend its lead on its wins. Personally, I'd rather have the extra cores. I have a dual core and it does all the general stuff I need it to, but it doesn't stop me from wanting a quad, even if I can't get it to the same OC speed.

Say thanks I could actually wait I have on board video with that board, until you original suggestions drops in price. I'll definitely take a look 4850 price is right but like I said if you really think 5770 will come down it might make more since to just wait. Thanks. :hello:
