I think this is the only place R600 can really make up ground. It's so TMU limited the only place it can achieve enough texture throughput to really shine is simply with high clocks.

As of now it has ~30% clock advantage over a stock 8800GTX (575mhz), which does give it the equivalent of 21 TMU's comparitivly rather than 16 just by the clock difference. Of course, one problem is the vendor OC'd 8800's around that clock up to 650, but ignoring them.

Anyway, by one gigahertz the TMU deficit in R600 versus a stock GTX is virtually erased. Maybe if AMD could at least push XTX stock clocks to 850mhz or so, it could make some difference.

I really don't see how R600 is TMU limited. Can we even be correct by even saying TMU anymore?:shock:

No tips about Crossfire SuperAA modes?

I expect new modes:

Super AA 16X = 8X MSAA + 8X MSAA
Super AA 18X = 8X MSAA + 8X MSAA + 2X SSAA

Combined modes with CFAA? (Possible?)
Super AA 18X (alt) = 8X MSAA + 8X MSAA + CFAA 2X narrow filter
Super AA 20X = 8X MSAA + 8X MSAA + CFAA 4X wide filter
(CF SSAA + CFAA makes no sense)
And the Ultimate AA mode!
Super AA 32X = 8X MSAA + 8X MSAA + CFAA edge detection filter

I expect that SuperAA works with non-stardard framebuffer formats, since X1K SuperAA only works in stardard FB format (no FP16 or 10 bit support).
And I want 16X MSAA in D3D caps too.

(sorry for my bad english) :cry:

The MC's have a combined bandwidth of 150Gbps. As you correctly point out, the ring has a combined bandwidth of almost 800Gbps. Your suggestion that this excess BW will somehow be useful, automatically implies that there will also be non-MC traffic on the ring, since the MC's definitely are not going to use it.
If this is not what you were thinking, what do you suggest it will be used for?

The ring will do an excellent job transporting 150Gbps over an 800Gbps bus. That's what I meant before by 'overdimensioning'.

A block diagram that shows everything down to the small crossbars, the location of arbiters, schedulers etc.? There are industrial espio...intelligence companies who make a business selling this kind of info to competitors. I don't recall ever seeing this kind of bus detail in a presentation about GPU. If ATI is not BS'ing all of us with their slides, the information we have now is as good as it gets.

Radio waves are invisible light. So are microwaves and x-rays, two other common forms of invisible light you must have encountered.

Because of conservation laws, if the energy didn't go into heat, or radiation, it would have to be stored somehow in the chip, either via chemical or nuclear processes (reactions that consume energy), or by doing physical work inside the chip (moving matter around, such as the case with rod-logic gates)

Thermodynamics and information theory tell us the ultimate penalty of data processing is erasure. Everything else can in theory by made to cost zero energy, but erasing a bit can't be made cheaper than k*t*log(2)

In this case, it pretty much is. The converted electrical energy used for crunching of data gets converted to heat as well. And since the GFX card doesn't output any energy, it's all "lost".

Not the oscillations of electrons are the problem, the bigger problem is the signal propagation without reflections. Refections are "teh evil" in HF-technology.

So besides Ep2, TF2 and portal you get DoD:Source for free to cover the distribution time.

w00h00, 82 degrees outside of the case

I have some feeling that w1zzard is helping fudo with the benchmark scores of late...

82 degrees does sound a lot like the temperatures on the 19xx's

http://www.tech2.com/india/reviews/p...1950xtx/2923/1
Also checked some temperatures of GTX/GTS's and the temperatures are all in that reported range

Adam and Jamie have another R600 urban legend/myth busted!

(and when you say the temperature is at the edge of the card.. that's where heat spreaders are for. we just have to believe the overclocking util for the real values..

Well in that pic person is measuring temp of power component(s) not core.

That is the temperature of power MOS or components for voltage regulation, not the chip core. The MOS or passive components of the supply circuit go often at that temperature or more

Ooops, already posted :)

right-o .. if the chip itself ran at 100 degrees, the unprotected back of the chip (also visible in that shot) would be able to fry eggs..

This is a example how Fruitzilla trying to save himself after he write pure BS yesterday :wink:

Hey mao5, hate to be a ball buster, but the screen shots are so different, its like night and day(pun intended). On the 1950 link you posted, there are fewer clouds in the sky=more sun light=better better shadow casting. In the 320M screen, there are more clouds=less light=dampened/reduced shadows. You could have 2 people play that game at the same exact time and neither would start the game or be at that point and have the exact same lighting/time of day sequence.

I don't know what they will use it for, but I think given the limitations you have rightly stated that it might be mostly for memory, but we don't know yet.

I agree.

That information is not enough to judge the decision of implementing the ring, IMHO of course.

Like the Nvidia Riva cards back in the ol' days! :lol:

It seems that AMD gives to reviewers of the 2900 XT a Enlight 500W with active PFC….

http://www.gpumania.com/foro/viewtop...r=asc&start=15

Fudo Fudo.. bad boy

But

The shadow quality is same on both. One image is darker but changing the brightness with an image editor reveals that there are no difference except for different character postures and color of the sky (lightning).

Oh, I remember that! I had a minor shock when I realized that the STB sticker on the chip (no coolers/fans back then...) was all but fried, it was black like burned paper after 2-3 weeks and fell off. I RMA'd it and got another Riva card from ELSA with a passive cooler on it (I think that was the first one with a cooler back then) :lol:

Fudo back-pedals furiously on the 750W issue:

http://www.fudzilla.com/index.php?op...d=830&Itemid=1

There is no forum at fudzilla that people need to link here every crap he posts ? What about judt delete the bookmark and ignore his site instead of giving him more hits each day ?

So there's still hope for my 2 years old Hiper 480W?

Specs: http://www.nordichardware.se/skrivel...pe-R-label.jpg

Pretty cheap upgrade if I can use my old PSU. And a bunch of free Valve games to add to my steam account. :smile:

OK. The fella who mentions that it's very easily possible to draw more than 225W with the 1x 8-pin and 1x 6-pin PCIe connectors that Kombatants' post showed is perfectly correct.

What the card actually draws at stock is around the 200W mark AFAI can tell. Temps are very good under full load and its quiet compared to a X1900XTX. OC'd, watercooled+OC'd by AIB or customer, it certainly has a lot of potential for more, so AMD has been very wise with this choice and only done the right thing with providing the 8-pin connectors. It's becoming the future anyway.

PCP&C are making a new revision for their Quad Silencer 750 to include the new 8-pin connectors. Corsair will ship adapters out if you email them. SilverStone has included them in a newer revision of their Olympia/Decathlon lineup too.

And before someone mentions the obvious, yes I know PCISIG specs for the upcoming universally accepted PCIe 2.0. They are not released to anyone unless you're a member.

1x 6-pin PCIe connector can draw +12V of 6.25A i.e. 75W
1x 8-pin PCIe connector can draw +12V of 12.5A i.e 150W
PCIe slot through motherboard can draw +12V of 5.5A & +3.3V of 3A i.e. ~75W

So yeah, they have expanded to incorporate peak draw of 300W for a certain reason. Power consumption is only set to rise.

And BTW, all this mess and people still believe or even pay attention to Inq/DT/Fud ?

Seriously guys. :no:

Yes, it's FUD in every sense of the word, to the point that it now looks like a "get my back" attempt from what I know. Just wait for the reviews and you'll see.

Kinc aka Marcus aka a good known overclocker also with the cards and the DFI RD600 will test and OC them to the limits very soon over at XS and NH. AFA NDA guys go, let me tell you something: they already believe that it's the biggest thing in, to make DreamHack Summer 2007 one of the best ever, if not the best. :wink:

So just hold away from to conjectural sayings out there and no digging at Kombatant young fella's. <3
