Official HD 2900 Discussion Thread

[GMX]

A64 didnt beat the P4 right out of the box with a huge margin. It first really manifested with the X2 series.

Also, Unless AMD GPUs got a process advantage over nVidia. Then its still nothing even remotely equal to the A64/P4 moniker.

I hate nVidias sole power with the 829$ Ultra

Yup you are right. It was exactly like the Conroe/AMD 64 TODAY (as some people claim, I do not know for sure)

People were saying their P4C's at moderate overclocks with HT were FAR more responsive and smoother in windows and disappointed with Clawhammers overclocked to around 2.2ghz-2.6ghz. Funny we have the same argument today but no one acknowledges yesterday.

Radeon HD 2900XT needs 750W+

http://www.fudzilla.com/index.php?op...=791&Itemid=34

1kw-1.5kw PSU for CF

If you consider capacitor aging, then yea you should get a 800w~ for 1 2900xt.

It's not that 2900xt needs 750w. I bet i could run it fine on a Tagan 580w fine, but not for long term.

Does the MCW60 waterblock fit on the new 2900 series?

I was talking about performance...

Also P4s with HT was more responsive compared to singlecore A64. It was alittle cheat method to experience the creamy smoothness of smp/dualcores on a singlecore.

That's the sort of comment has the PSU companies are laughing all the way to giga-watt land...

A single HD 2900XT will NOT need a 750/800w PSU, even after capacitor aging. I would be surprised if it needed any more than a quality 550w, seeing that you can run a single 8800GTX system off a 400w PSU and a pair off a 620w Corsair, NOT that I'm recommending doing either. My choice? 600w for the single and 800 for CF.

Totally agree. If max power consumption can be even 300W for the card. Well other hardware in the case will be under 300W total unless you have a highly OC'ed quad then sure needing a bigger PSU might do you good. CF will need a bigger one but surely a 850W will do you more then good on dual core systems, quad core a 1k PSU would be your ideal solution.

Lets see about that after a few months or a year. I've experienced it myself.


Ohh funny that my AXP system which use to have a Antec TP 480w couldn't handle the overclock anymore. I wonder why

If you refuse to consider aging, then you are a fool

[alayashu]

HD 2900XT looks like a very powerful board, but if its power consumption is as big as rumored... crap.
nice to hear official statements from AMD-ATI saying power consumption will be a big focus from now on though.


/*OT. worrying to see people still think P4 was better than A64, single cores or not*/

/*OT. worrying to see people still think P4 was better than A64, single cores or not*/

Facts. It WAS smoother and responsive. It got beaten in benchmarks. Not as much as Conroe beat A64. A P4C at 3.8ghz is about equal to A64 around 2.6-7ghz. How many Clawhammers in 2003/2004 clocked to that very easily?

I could say the same thing but its probably not "over". Conroe is better than A64. *waits for the all the guys that kneel to their A64 and treat it like god"

Off Topic:
Sweet! So having less performance but better response while loaded at 100% because it couldn't keep itself busy means it was better. I should have reminded my friend that when he was getting ~40fps in CS:S with his 3.6GHz P4 and I was getting 80FPS with my Opteron at 2.8. "who cares that when you're in a big firefight that your machine lags, when you're running prime you can do other stuff and doesn't feel like you are doing anything!!!"

Great point... I think GMX lost another bout.

[alayashu]

the 3.8 was, averaging most tests, about as fast as a 2.4 K8, but consumed more energy.
In rendering, the P4 3.73 ExtremeEdition was a tad slower than a 2ghz K8 btw, for a best-case pro-K8 real world scenario.
leave netburst rest in peace, it was a big failure in every aspect(performance/consumption-heat/etc)

ehem, HD 2900 topic...?

Did you have a 2.8Ghz Opteron in 2004?

[Shintai]

I really doubt we need a 1000W PSU for CF. Its simply a matter on how many Amps the PSU can do on the 12V rails. And how efficient it is.

I would say a good 650W would do it.

But its in the red zone.

Again, 11 days left till we hopefully know performance and power consumption.

[cantankerous]

How does making dinner while playing with your new R600 sound? Apparently the card gets hot enough to boil water...

What happened to that top to bottom R600 family launch? Where is the 2900XL?

I really hope thats wrong. But on the other hand. We got something like a 8800 cooler that needs to remove about 50% more heat.

But again..its FUDzilla..

Did I say I was ignoring aging? No. I was just saying that there's no need to make as much of a point of it as you seem to suggest.

As for the AXP overclock, can you prove it was the PSU at fault? Possibility it could have been the mobo, or CPU? How can you be sure? And also, I think you're kidding yourself if you think the TP 480w was anything other than a 'budget' PSU in the first place.

Back on subject, I really don't think that the power consumption of the 2900XT is gonna as shocking as is being made out. And, if it's because of the extra stress DX10 puts on the card, I wouldn't be surprised if the 8800GTX's power consumption goes up a bit as well with the DX10 usage.

Final point, I want independant benches!!

But again..its FUDzilla..

If the 8800GTX puts out 178W so to say at max and the 2900XT can use a max of 225W (max the power connectors will do with the 2x 6-Pins). The 8800GTX has 26.4% less heat than the 2900XT or the 2900XT has 20.9% more heat than the 8800GTX.

But the 8800GTX aint 178W..its far far from it.

The TDP is 177W according to NV. In use at stock its been measured at a lot less. A reasonable OC then maybe it gets to 150W.

As said it has a TDP of that much. While it might use less currently we aren't sure if it will use more for DX10 apps or not either.

About the PSU, here

Hi there

Our system had an Enermax 1000W PSU.

I have the ATI Tech/Fact sheet here so upto 200W is requirement at stock clocks with 2x6pin connectors.

If overclocking then you need 1x8pin and 1x6pin connected and then it consumes upto 225W.

I hope ATI don't bash me for stating this but I don't want misleading information such as that going around.

Fact is a decent quality 400-500W PSU will run of these cards fine if your running a Core 2 DUO system or Athlon X2 based system.

here

Hi there

Also regarding this 100c nonsence.

This is making my blood boil now.

AMD/ATI let me tell these guys the real facts about this card because the utter crap on the internet is literally that, CRAP!

The card is quiet, in fact its more or less silent even after a good gaming session. It also stays in the 70c-80c under full load whilst overclocked and still remains quiet.

At stock speeds its generally around the 60c-70c mark and the heatsink does not burn to the touch like an 8800GTX or X1950 XTX, so the card can be handled even after a mad benchmarking session.

Umm 3 years ago no it wasn't budget. ANd to prove it's PSU? Easy, because a new Tagan i had spare does the job like before.

[wickedld9]

Did you have a 2.8Ghz Opteron in 2004?

No, I had a 2.8GHz A64 4000+. EE 3.46 was the fastest Intel. Since when did this become a discussion about 2004?


Back on the real topic!! TDP is up to 177w. That xbit setup isn't close to pushing a GTX.

[FghtinIrshNvrDi]

I wouldn't doubt the 100*C thing. My x1950xt runs routinely at 80 while folding, and above that when doing 3dmark06.
