The NEXT LAST R600 Rumours & Speculation Thread

Why? I knew R580 had 16.

So did X800 before it, years ago.

 

And my X1950GT has 12.

 

So the program is innacurate? Fair enough.

Still odd it lists out 8800 at 32 though.

 

No:

 

And so has my Pro (well,GT actually but that's not the point.. )

 

Just a small note: I personally haven't been able to date to combine soft shadows with MSAA in FEAR. And before anyone is quick enough to state "I do" first watch the darned timedemo if there are actually softshadows present.

As for the DT results in general, it's too early to jump to any conclusions. That doesn't change though my personal opinion either that R600 will have only a modest performance advantage over it's direct competitor on average.

 

Xenos has plenty of games to prove itself. It's a good chip. And it's games have looked just as good as it's competitor (that came out a year later), which is really all that counts in that sector.

It probably has 16 TMU's too.

 

Xenos' competitor didn't came out a year later, the game console carrying it did.
My bet is that the RSX essential design was finished before the Xenos, since it is a much closer relative to the desktop GPU's available at that time.

 

Well, here's what I think will happen. AMD will release the XT with newer stable drivers and it will beat the GTS. It might beat the GTX if you OC it to 845+ on the core. This is of course with the GTX factory OC'd to 650MHz. I heard the OC's GTX in the DT article is watercooled and costs $939.00. But no matter. I think the GTX Ultra will just be a 650MHz card with a larger cooler. It most likely won't OC much higher than that on an air cooler.

It seems there is a problem with the XTX, something probably about the GDDR4, etc. It could just be a driver bug on the XTX cuz it's hard to believe the XTX is the same speed as the XT with faster memory. Also, I've seen some benchmarks showing the X1950XTX beating the HD2900XT-X in a few games. This has got to be wrong.

I think DT made a mistake somewhere in benching. I don't think they just made up the numbers but they could have put the settings of the new XT/XTX cards at settings that take a big hit. Maybe there's some IQ settings that look great but just kill performance. Who knows?

Also, at the same time DT could have used some performance optimizations on the GTX(or maybe not) to boost its numbers. Many things could have happened. I think the XT's drivers are young and there are a few different versions floating around so who knows which one actually work best.

Many questions to answer. Yes DT is getting a sh*tload of hits on their website for these "reviews". I wouldn't put it past Fud and DT to throw number and rewiews back and forth for more traffic. And all DT has to do after the real reviews come out that contradict their "reviews" is to say, oops, our bad, we had some settings wrong, or the AA was at 24, we used the wrong drivers, etc, etc.

Gibbo over at Overclockers rated the XT at a 5/6 out of rating of 1-10 with the GTX being in the middle as a 5. Later Gibbo heard some other people that had XTs were getting some higher marks with newer drivers and so then Gibbo said he would probably rate it a 7 with these newer drivers compared to his numbers. (This is what I surmized, don't shoot me if not 100% right, but that's my assesment)

I guess we'll see May 2nd, right?

 

Well, of course I know that, but I dont feel like explaining every little thing in every post

They were more like same generation parts, yes. Xenos is still a kickbutt little chip. The OP just doesn't understand consoles at all by the very nature of his question

Xenos was very forward looking compared to RSX, and it sports 10MB of EDRAM in the same die space as the latter with none. It's a very excellent design. One could say ATI's last, really.

 

Those GPUDIP results are not very useful, e.g. on G80 "18: Cel Shading" has 23 instructions/70 FLOPs and executes 6% slower than a 1 instruction/6 FLOP shader (MAD). In both cases, the shader has a single texture fetch.

There is a trick to get it to run with AA and SS on, screenshot included.

Am I just misreading or (aside from questions of accuracy/comparibility) are people saying that those Gpudip results indicate poor performance for R600?

I read most of those results as being about twice as fast as the G80

 

I might have neglected to mention that I meant the timedemo, but I thought it was obvious since the debate was about benchmark results.

FEAR was never meant to combine Soft shadows and MSAA; in game it does lead to occassional side-effects.

 

I know you meant the benchmark, thats why I linked the trick to you. Yes it works in the FEAR inbuilt benchmark and it is very obvious (just ran the inbuilt benchmark for memories sake and it's visible).

True.

 

Where is this score on GPUDIP that people are talking about? That number at the bottom of the page? Isn't that the column under processing time totalled up? I never added them, but I thought for sure that was total time taken. I'm at about 168 secs or so with my x800 pro modded.

 

Wouldn't it still be a bottleneck the same though? Just moved up the chain a bit?

BTW, if it's obviously less than the hardware can do, why is it more than the X1950GT can do?

I do hope ATI put at least 24 in there though.

 

I suspect it may be GPGPU done right that cost an unknown amount of transistors.

WRT the XTX, I dont understand why they dont just respin the card with +100 Mhz over the XT (DTs overclock went to about 850 Mhz) and 1 gig of 2 ghz GDDR3 memory. The G80 ultra has 2.16 Ghz GDDR3 ram, thats not far from 2.2 Ghz GDDR4 ram. It may be that the XTX has to suffer the same GPU speed as the XT in order to conserve power consumption. As usual, we wont know until more technologically skilled review sites get their hands on samples.

 

Yeah, that number is just total time. Overall I think it's best to ignore the results entirely.

Rys, where are you? Take a bow.
