The ATI Radeon 5XXX Thread

And yet it consumes more power and puts out more heat than the GT200b...

Very true, hope they improved upon these things on the new chips.

[Solus Corvus]

haha, we all know stanford cant code for sh*t.
this is from their FAQ:

besides this cuda with the new mimd architecture is going to add a huge speed up due to the fact mimd achieves maximum ipc.

I wonder if that will continue to be the case under OpenCL.

And yet it consumes more power and puts out more heat than the GT200b...

At idle.

At idle.

And load. The GTX280 uses more power than the 4890 but not the GTX285.

and ofcourse furmark maximum where ati cards get over 9000 fps and suck up ungodly amounts of power

There is at least one new name you will hear next week, and it is a neat one.

Now what's the boy talking?

[Chickenfeed]

I believe Charlie is saying that one of the new cards is called something other than what everyone has assumed / rumored thus far. Whether its actually a different gpu or just a different model who knows. But I do agree with him, the level of secrecy AMD have maintained is rather impressive.

As far as the whole power usage debate, I do hope to high hell that these new cards are competitive in power usage being they are on a new process. If I see a 300watt single gpu card in the next 6 months I'll cry. Hopefully AMD also have their idle usage down this time. The 4xxx's sucked big time compared to the GT200s as far as that is concerned. I still don't understand why they didn't opt for lower 2d clocks as manually reducing them doesn't seem to cause any problems ( Nvidia's 2d clocks are way way lower proportionally )

LoL

That graph is wrong.

[eleeter]

That graph is wrong.

Thanks for the detailed explanation.

.....who cares about current soon to be last generation power usage. Bring on the new stuff! The wait is killing me.

Indeed only 3 or 4 days (depending where you are)

OMFG !!! im excited

[Wesker]

this is why I like nvidia:
nvidia cards on F@H: 4 petaflops with 16,500 gpu's
ATi cards on F@H: 1 petaflop with 10,000 gpu's

While it's great for Nvidia to have such a close relationship with the researchers at Stanford, you're completely overlooking in-game performance.

And yet it consumes more power and puts out more heat than the GT200b...

You have got to be joking...

[RejZoR]

Of course AMD has so low flops score if 3/4 of the shader units aren't even utilized because of lame client coding? And AMD doesn't have much to do with that.

[tajoh111]

You have got to be joking...

Its almost a certainty that the 4870 uses more power in idle, while its a certainty that the gt200 uses more power in peak.

However unless you game more than you actually use your computer or bench(which you don't care about power in the first place), then the energy usage cost is much higher to run a 4870.

They could be constantly running a GPGPU application of some sort. In that case it would be cheaper to run a 4890 then a 275, 280, or 285. Though you'd probably get more work per energy spent on the NV cards. We will see if OpenCL changes that scene at all in one direction or the other.

Probably something to do with this:

I know that was the case when the 4870 first launched, but I would like to see recent power consumption figures.

At launch, PowerPlay was broken with the RV770 core only downclocking to 500MHz. Now, even RV790 downclocks to 240MHz and I assume that ATI made changes to idle state definitions through driver updates.

30 watt idle for 5870?:

Wow, that would be utterly fantastic. I like it.

30w seems unbelievable though.

[Jamesrt2004]

*snip the pics*

and ofcourse furmark maximum where ati cards get over 9000 fps and suck up ungodly amounts of power

how do you even measure just the cars power withdraw

that 320w in the furmark seems unbelivable seeming you can run it on pcie 1.1 so that would be 2 adapters @ 75w each plus pcie slot only gives 75w so 225w max so yeah

tbh I believe the one above it more seems more reasonable I always thought believed ati had crap power idle settings this time around and nvidia had good ones but just for the obvious reasons that the nvidia cards die size was/nearly twice the size is easy indicator of power consumption

[CrimInalA]

The 5870 cards are said to be slightly longer than a 2900xt . Means I'm out , my case can't take it . Since my 2900 only has only 1cm free space .

[labs23]

Wow, that would be utterly fantastic. I like it.

30w seems unbelievable though.

And 4890 idles at what W?

[Origin_Unknown]

nvidias can of whoopass was not a can but more of sandvich bag full of moldy whoop ass

i really lol'd @ this

[jaredpace]

And 4890 idles at what W?

--cards: 4850 4870 3870X2 GTX280 9800GX2 9800GTX+ 9800GTX
Idle load 123 --149 ---119 --- 127 ----174 ---- N/A ----- 141
Full load 203 --229 ---289 --- 279 ----313 ---- N/A ----- 223

Edit: Actual card consumption here:

http://www.xbitlabs.com/articles/vid...c_5.html#sect0

A 4890 is slightly less than a 48701gb at idle ~ 45 watts. The anandtech graphs (that i first posted) are total system power consumption. So you have a 4890 @ 43w idle, 121w load, both hexus, xbit, and anand agree the rv770/790 uses ~80w going from 2d-> 3d. And now supposedly, the 5870 @ 30w idle & 195w load (165w between 2d->3d!). Maybe they've fixed the deal with the ram's idle power draw?
Edit again: 80watts for running 800 shaders and 160 watts for 1600?

[Calmatory]

Wow, that would be utterly fantastic. I like it.

30w seems unbelievable though.

Just great. A graphics card using more power at idle than my computer comsumes at full load.

[labs23]

jared - Thanks for the graphs.

I'm starting to think this 30W idle is BS. I mean how will they(AMD) do that?
