R580 on B3D?

[CJ]

I doubt it if B3D already has R580, unless the ATi R580 Tour already hit the UK. It will hit Amsterdam within 2 weeks and ATi will use the event to heavily promote R580. Dunno if this is a pan-European event or just for the Netherlands.

 

[Fodder]

Oops, sorry, I meant for any future updates, i.e. R590 or whatever?

Last I heard R590 is just R580 on 80nm, and will only arrive if ATI think they have room before R600.

Last I heard R590 is just R580 on 80nm, and will only arrive if ATI think they have room before R600.

I thought they were taking the sane approach first and start out with RV535 on 80nm low-k before laying it out on 65nm (r600 will be 80nm or 65nm methinks)

 

[Fodder]

Well, there's RV535/540 (and possibly RV560?) to practise 80nm on.

Edit: Yeah, 535, finger-spasm

 

[neliz]

Well, there's RV356/540 (and possibly RV560?) to practise 80nm on.

535 and 60, we've read the same rumours...

65nm is production ready now so I reckon that, with the launch of the unified shader line ati and nvidia would be wise to have their low end model on 65nm, unless offcourse, they want to stick to 80nm for a while, while the rest of the world+dog is on 65nm.

What's RV356 Typo, I assume.

 

[neliz]

What's RV356

That's RV535 for people with 12 fingers!

 

[Fodder]

What's RV356 Typo, I assume.

Indeed. I meant 535.

Given that I'm struggling with 10, maybe another 2 would help?

You'd only break the caps on your 1900 review card with the extra fingers..

Who's 65 nM is production ready? The only company currently in volume production is Intel. No one else has committed to 65 nM volume production within the next 6 months. TSMC only managed volume 90 nM production months before Intel started 65 nM and it doesn't appear that they'll be on 65 nM soon. Next two up are AMD and IBM which might make volume 65 nM production by the summer.

65 nM isn't coming to PC graphics for at least a year.

End of 2006 would indeed seem to be the earliest at TSMC. Not before R650 for ATI then, which would be fitting.

Edit: Corrected. Blood champagne levels still high. :smile:

There goes Fuad contradicting himself yet again within the same article on R580 clock speeds. This guy is simply incomprehensible.

"Unlike our Chinese friends from HKEPC reported the X1900XTX will be clocked at 650 MHz core and 1550 MHz memory. It will end up very close to the original R520 clock speeds". -Faud

Um, so what is "very close" to the R520's original clock speed without actually being the R520's original clock speed? The only other speed I can think of would be lower than the R520 using this logic.

In other news: the sun rises in the east and sets in the west.

To translate: the sun rises in a direction which was previously thought to be not north but we now know it to not be south and sets in a direction which was thought to be not south but now is known to be not north.

Now I seriously feel like I'm diagonally parked in a parallel universe

yes, newer processes always come late on GPUs anyway (90nm is coming right now and it's been there for CPUs since Prescott, for 130nm it was the same).
I guess it's because GPUs are more complex in terms of logics stuff, whereas most of transistor count on CPUs is for L2 cache.

and for some reason GPUs always use the intermediate processes (150nm, 110nm, now 80nm), which the CPUs never use (don't know why, it's not worth it?).

The circuits used in CPU are in general more complex than those used in GPUs. CPU tend to come out quicker on newer processes because the companies selling those CPUs make more money and will make an even greater amount of money on the new process which they've researched, designed, and built in fabs which they own.

In contrast, neither Nvidia nor ATI own any fabs and instead of reliant on TSMC and other foundry semiconductor manufacturers. TSMC doesn't have the resources to invest on the new processes as far as research for new equipment etc. A lot of the semiconductor manufacturing equipment is jointly researched and designed with the big CPU companies.

Yeah for some northbridgetype chip or something relative small i guess. Late H1 07 would be my best guestimate for volume of highend GPUs at 65nm in TSMC´foundrys.
