Huddy says "R600"

That statement and such a blatant simplification is kind of an insult to mostly everything Beyond3D stands for, imo... I'm honestly tired of this kind of overconfidence again, again, and again. I know it's not really intentional, but that's not really a reason to continue doing so either.

ok. I discount Higher Clock domain Unit on G80 .(200W~250W)R600 is faster than G80 (150W)

. sorry for my malfeasance.

 

Before Nvidia do refresh product in 3 months; they have to find out about R600 first.

A. Is it going to have 512-bit memory internal + external at the same time
B. Is it going to have over 2000MHz+ frequency GDDR4 memory
C. Is it true that it will have true 64 physical pipelines
D. Or it will catch-up to Nvidia specs first; barely match nvidia...

 

That's not the point. You're talking like you know everything about these architectures and had the possibility to benchmark both of them in person on similarly specced machines. But obviously, you haven't. Even with the full specifications, you have NO idea if the two chips would have identical performance per clock. You could easily claim the performance of R420 and NV40 were similar per clock if you "simplified" a few things, but guess what, they were NOT! So what you're saying is downright stupid.

Also, you keep talking like everything you say is fact. Yet the "facts" change every 3 days in your posts. I'm not saying part of your information isn't correct, and I'm sure some of it is. That's why it's still nice to see you posting what you think from time to time. But as it is, you are merely adding noise to the forum with short posts full of unreliable content, the whole thing added with a huge amount of confidence in information that you shouldn't be that certain about, even if your source was Dave Orton or Jen Hsun Huang themselves! There is no such thing as a fully reliable source, and it's about time you learn that. This is getting extremely annoying.

I'd like to see you contributing to these forums of course! But with a tad less... extreme posting habits. That is, it'd be nice if you contributed more than a ton of minuscule posts that are only right 30-40% of the time, maximum. While that's not a bad percentage, the fact you write it in your quite awful english (it's not your fault, I know... It just isn't very fun to read and understand though) and with that confidence is ridiculous. Even more so considering the amount of posts you make in a week... This is all my opinion, but I think others will most likely agree. As I said, we appreciate some of your contributions, but often your posting style and opinions can be VERY annoying for the rest of us!

What I want to know is if R600 has any surprises up the ol' sleeve like G80 may, specifically divergently clocked domains. ATI seemed to make a big deal out of ******** a year or two ago and some comment about how it wasy extremely vital to ATI.

I would guess that we also don't know everything about R600. Sure, ATI will leverage Xenos' unified shaders and the memory controller in R5x0 (and both should be quite well tweaked and optimized), but those will be 15+ months old by the time R600 launches. Obviously a lot of time has to go into meeting the D3D10 spec and Xenos was a large side project, but I am expecting some surprises from ATI.

 

Great, and now you go mentioning it out of the blue!

/me whistles walking away....

Seriously though, with how the industry goes in regards to technology in general, what is available to NV is available to ATI and vice versa. It is all about choice. Seeing as G80 may have ALUs clocked much higher than the rest of the chip, it does raise the question about unsaid technology agreement The big selling points, made to the public, were "According to Intrinsity, circuit designers using Fast14 can be more productive, allowing them to design processors that can run at high clock rates" and "Intrinsity's Fast14 technology could enable ATI to design GPU logic that clocks up to four times faster than today's clock speeds, according to a company spokesman for Intrinsity. Current high end GPUs clock in the 400-600MHz range, so a chip using Fast14 technology could deliver GPUs that run in the 1.6 GHz to 2.4 GHz range. Fast14 doesn't help with memory clocks, including onboard cache memory, so only the logic portion of the chip would run at the high clock rates".

PR bull aside (it seems in reality the deal was about delivering more performance per silicon dollar), the fact we are seeing a G80 leaks indicating nearly 1.5GHz shader ALUs raises an eyebrow. In many ways G80 is sounding a lot like what many were expecting from R600: Unified Shaders, a bit of bandwidth, and ALUs with high clock speeds. Maybe someone switched up the PR slides If you had handed me the above info and asked me what GPU it was I would have said R600... Anyhow, I wouldn't be surprised if R600 was clocked very fast, and if G80 is what we think it is it better be!

 

That's what I want to know! Intrinistiy was talking 2GHz and 2.5GHz for the 130nm process. There was a brief period where they had 4GHz listed for 65nm then they replaced it with greater than 3GHz without mentioning the process.

 

Why's the speed of mainstream parts, RV5xx, relevant to R600?

That "V" in the name means they're built to a cost. The board itself will be built to a cost as well, which ultimately means there's no reason for ATI to build them for overclockability. Particularly as this far into the lifetime of R5xx the positioning of these SKUs is well understood. They know what they're aiming for, there's no need to aim higher.

Each process node has speed grades. It's reasonable to assume that RV5xx is using the GT grade of 80nm, while R600 will be using the high-speed grade of 80nm:

We should then see (some of?) the performance/mainstream/value R6xx variants being introduced on 65nm, leaving the enthusiast level R600 waiting for refresh, ~9 months later, before it hits 65nm...

http://www.beyond3d.com/forum/showthread.php?t=29612

What's the timing on 65nm? How much of the timing of R600 is tied into the timing of a "big bang" R6xx range, with a mix of 80nm HS and 65nm GT parts releasing over the period of one quarter, say?

Thread locked, as it became a tad messy (not more so than the G80 one, but we'll be fixing that soon too) - please use the new one for all further R600/R6xx discussion!
