The 8 core showdown and analysis thread.

[humbug]

I've got a 500w PSU and it ran CF290s. Lol, love people who think you need huge PSUs for rigs. They do eventually run down, but 500w (decent) would last a good while for any single GPU. The argument might be i could have got a 750w+ for th price i paid for my 500w and it would have lasted longer. Noiser though

Thats right on the ragged edge, stock 290's pull about ~250 Watts each

I was getting around 620-650w at the wall, so yeah over the red line lol.
Overclocked 4790k as well. My PSU might be a '500w' model, overloads like a boss though. Assuming 90% efficiency, on the redline is 550w from the wall.

Still, for a passive unit. Damn fine show, old boy

Yeah thats impressive.

Its got me thinking, i have my GPU running 1100/1407, CPU @ 4.5ghz, Stock GPU = 947/1250, CPU = 4Ghz

The GPU throttles down with anything less than +5% BPL. its has a 300 Watt AIB BIOS, so it using ~315 Watts.
On the CPU it power overrun shuts off with anything less than 120%, Its a 140 Watt MOBO so +20% = 170 Watts + 315 Watts = 485 Watts

+ MOBO
+ 1x SSD
+ 2x Mechanical Drives
+ 4x 2GB RAM
+ CPU Water Pump
+ 3x 120mm Fans
+ 1x 200mm Fan

??????

I need a power meter

I measured the 7990 when mining at the wall (which meant no CPU load) flat out was more than my 650w could take running for extended periods. Say what you like about a decent 500w but you answered the point we were making all along - why get a 500 when you can get a 750 for very little more.. at least with a larger unit you could add more devices or go crossfire/sli at a later date. Considering the 8+ years statement, I know which I would go for!

 

[james.miller]

I dont think the 7990 counts as a single gpu somehow, so no

Say what you like about a decent 500w but you answered the point we were making all along - why get a 500 when you can get a 750 for very little more..

It's pretty clear what mals point was,

your PSU is way too small, try at least 750 W

Say what you like about a decent 500w but you answered the point we were making all along - why get a 500 when you can get a 750 for very little more..

Not the same point at all.

I like silence, find me a decent 750w passive PSU. True passive, not silent fan.
If a single 7990 made your 650w unit trip, was a rubbish PSU. Either than or the heat build up sent it over the edge, and the onus of blame comes down on you for that one.

As for the 8 year statement.
The rig the guy above built, for gaming would struggle to pull more than 300w. So his 550w unit would be fine.

Never will I risk overloading a psu again.
I destroyed my 24 pin ATX due to to much draw through it

I now have an evga p2 1000w

And on the '280x is enough'
It is if you want 1080p

My monitor is a 27in. 280x is absolutely not enough. 2 is just just enough to cover most things.
which is what I run.
And you can absolutely tell a difference in a 27in between 1080p and 1440p

If you're on a tight budget, and never plan on getting a second card (starting with a decent card to begin with) then opting for a lower wattage PSU is perfectly fine. Computers really don't draw as much power as people think, especially when stock.

If you've got no budget constraints, then yes. 100% agree, why buy a lower tier PSU when for the few quid more you wont be limiting your options down the line. Makes sense as most PSUs nowdays come with 0db fan (low loads the unit is passive)

My posts above are not telling people to buy low wattage PSUs, thought i would clarify that. I've chosen silence and only run 1 GPU regardless of more being in my system (only tested my second 290 to proove, to myself. That the 500w is enough! Was only loaded for a 3D11 run as well, wouldn't personally risk overloading for long periods)

Mal posted two hours later.

You dont need more than 550w for any single gpu. by all means buy a bigger psu if you need to, but it shouldnt be a consideration unless you are serious about your overclocking. Ie, 780 ti power usage http://www.anandtech.com/show/7492/the-geforce-gtx-780-ti-review/16

no i meant the mechanical drive... no need for more than 500gb

gpu is low.... yes because you'll sooner or later want to upgrade....i.e an R9 290 requires about 700W Overclocked and that card will be be pretty cheap next year.... but not for him because he'll need another psu as well.

That's down to whoever is buying the bloody computer, surely...
1TB isn't enough, 2TB isn't enough....for me, at least

yes but he'll get the bug and want to upgrade, because everybody here does.

you dont become a regular on this forum without being seduced by all the gear up for sale you cant help yourself, it's very hard to say no

what i do is if i get bored of a game it's deleted, i never keep old games, so my storage never rises much.

my old rig is 60gb Kingston ssd...........500 black Western

 

[james.miller]

Subjective, im using about 400gb on my pc and 3tb on my server. next to some people that's nothing at all.

Can't you at least try to do some research before you bleat that rubbish? you wont even be pulling that with your 7990, why on earth do you think a single r290 will?

overclocked 290x = 526w. At the wall.

Not on about Mal, I was on about your own words!

James must be defending vyper as he is being subjective. You find some strange banding of people clubbing together here, anyway shall refrain and get on with something more constructive than arguing on forums with people like Phixsator has highlighted in his picture!

You are aware you can do more than game on a computer?

But it isn't a like for like comparison because as we know, the AMD suffers due to IPC and single threaded performance.

That's the sort of crap people want to see. Then they can go "Oh look ! Intel win again, wow etc"

But it isn't that clearly cut I'm afraid. When you actually sit down and take a look at the figures sure, the Intel wins. But it's not all about what product costs the most money.

People say that Piledriver is a failure. If that's the case then given that it's an extension product of Bulldozer why are AMD still making it and why, if no one buys them, are they still selling it?

Surely they would have gone bankrupt years ago (right at the launch of Bulldozer) if that was the case yes?

No instead of that they are binning chips and packing them with AIOs that supposedly no one buys. If their marketing staff really were the blind gibbons people say they are they would be no more.

The elite few that want the absolute best and will pay the massively, disgustingly over inflated price for it are the minority. They are the 1% of the 1% and no company exists purely to pander to their needs. Trust me on that, business does not work that way.

I bet there are more people reading this thread with an AMD CPU (and not posting) than there are the type who come here to rubbish AMD.

Apart from it is a like for like performance disable HT on the intel so its 6 cores vs 6 cores, you CANNOT get a more equal show down! lol

What your talking about is an amd 8 core vs intel i7 for 8 threads as they are the same price bracket.

Im not interested in who makes each part - I am a man of science, scientificially both processors running at the same speed will give you like for like, yes as you say the intel will win as each core is more powerful (you yourself have an intel so its all good), once each core is more powerful..............then it quite simply becomes as you say, if the software supports and benefits from more cores.

Your main point which I take is, HOW MUCH PERFORMANCE PER £££ ..........yeah AMD is pretty good here IF you have software thats using cores a lot...........I do a lot of video editing, so maybe I would find it useful.........however I do a lot of other stuff as well, made only for duel core or single..............on balance the i7 is the best 'all rounder' for roughly similar money (especially if you go 2nd hand for a sandy bridge, value here is amazing)

Anyways yeah all good, just choose whats best for your needs,lol.

look :- ``750W or greater PSU required`` right here, just look at the Powercooler 290X
http://www.overclockers.co.uk/showproduct.php?prodid=GX-167-PC&groupid=701&catid=56&subcat=1752

you'll need 700 to 750 watt with everything else in your rig... EVERYTHING ELSE....esp if you overclock the CPU as well

500W TO 600W is too low for future proofing, it's not cost effective, i'd go for 750w to 1000w

With over 3000 posts i can't believe you just did that, are you telling us you don't know they just put any old number up with those to cover their backs in case you get cheap and nasty PSU's?

Do you honestly believe the card pulls more than 500 Watts? don't be ridiculous!

A reference stock card pulls about 250 Watt's, overclocked they pull around 300.

 

[~>Dg<~]

a good branded 600w should be more than fine but with how much difference psu cost why stress about it pay a tenner more maybe and get a slighlty bigger psu and not worry about it.
