first r420 review leak

[DerekBaker]

An extreme pipeline?

10k 3dmark score is a little disappointing, considering it's more than double the raw processing power of the 9800xt i was hoping to see atleast 12k+

AFAICR, wasn't NV40's 14K number done in 800x600?

Another piece of commonplace : history repeats itself. With the increased number of pipelines, added functionality, etc. they might run out of transistors with the XBox2 chip too. Not very likely, I know, but you can't just disregard past obstacles 'cause they tend to bite you in the back when you least expect it.

Trilinear TMUs would inrease the transistor budget that much?

Sorry, I don't really get what you are suggesting...
I just noted that now the R420 can do 32x0 just like the NV40, so that's no longer a trump card for nVidia.

It was 16*0 vs 16*0 for R3xx vs NV3x too. Difference being that while NV had higher clockspeeds in the former generation, tables have reversed.

Clock for clock I saw R3xx and NV3x running neck to neck in stencil fillrate bound tests.

NVIDIA probably lost the trump card but not due to the amount of Z/stencil units, but the lower clockspeed, hence the math. I can see a ~30% advantage in pure stencil fill-rates what do you see?

It was.

It was.

It wasn't, it was an OC 6800U on a OC PIV.

Depends. S3 showed us that it doesn't have to (quite some time ago too), but ATi thought otherwise last time, sooo... we'll see.

It was 16*0 vs 16*0 for R3xx vs NV3x too.

Weird, somehow I had a misconception of 8*0 for R3x0... don't ask.

Ah, now I understand. I though the second line somehow referred to the X800Pro.Frequency of errors reaching critical limits... must...have...more...coffee...


Evildeus : got proof?

Coincedentally it also gets 14k at 800x600 anyways, according to macci

 

[Ailuros]

Ok I just received an indirect warning considering that specific slide. Can anyone possibly clarify the situation about the amount of stencil ops per clock without getting into trouble? *cough*

Listen to the presentation? What's yours?

 

[Joe DeFuria]

I have to say, it seems to me that the X800XT's GL drivers are holding it back a bit. In D3D Shader apps (Far Cry), the X800XT pulls away pretty dramatically. GL is another story.

So now we know why there is a GL re-write under way.

/Waits patiently for B3D's synthetic shader benchmarks...

Sorry for the OT but some of you need to grow the f*ck up, literally

Yup, ATI knows their GL drivers need to freshen up

Yes really ashamed to wake up this morning and see all theses links here

Listen to the presentation?

So basically I'll have to take your word for it. Got no probs with that, so far.

Agree with 1. But for the other two, this is the internet: when it's out, it's out.

I agree don't delete or edit there shit.....but man it's your own guys fault people have this info now and its spreading all over the net...

I found GT4 results interesting:

Performance in line with fillrate...

Well, it's not my word it's the words of the speaker. Now why should i take your word, because it's yours isn't it?

 

[Evildeus]

Moreover the 6800U seems to be limited in VS performance against the X800.

 

[stevem]

In line with clockspeed differential.
