R520 info thread #(9!)^9

that has never been the case. This core has had the most work done to its internals since the R300. We remember how awesome that card was with the drivers that launched with it right . Then we've had releases resembling the most recent NV40 where the card launched in summer, but it took to the holidays for the drivers to mature. That core made up alot of space in terms of performance gap between it and the X800XT/PE in a 6 month period after launch.

The lesson is that no drivers launched with a card are their best performing. Usually takes some time after launch for that.

 

The respins weren't ment to change the way the chip executes data so in all likelyhood the drivers are mature by now. If they still aren't mature well thats just not good for publicity.

 

Re ATI calling out texture compression on the diagrams this time, I was just reading Anand's article on Valve HDR and noticed this line:

Could one hope?

 

No doubt, the true test of drivers is when thousands of monkeys start beating on them after a card is launched. Try as they might, there's no substitute for a real luggage test.

 

hmm isn't Open EXR a compression format?

 

I just don't think 4 months gives them much time to do much with the drivers.

 

It does, though, because previous to launch, they can't build large numbers of test systems to do nearly as much testing as they can after launch. The quicker response time between when a driver change is implemented and when it is tested on a variety of platforms and software allows for much quicker development of the driver.

 

If my name was Makedon I'm not sure I'd consider that a compliment.

 

I don't think so. Neither decompression from TMU to texture cache nor compression from texture cache to TMU make any sense. I think it's just a c&p mistake in the diagram.

That description in this paragraph doesn't relate to threading at all. The threading NVidia refers to in the VS is about having multiple vertices in flight in a single VS unit, switching between them to cover the instruction latencies.

The VS array is MIMD (meaning that each VS unit has its own instruction pointer and can branch independently). Each vector unit is SIMD.

 

I don't give a damn about the architecture itself. What I'd like to know:

- is it faster than the GTX? How much?
- does it have better IQ or some new IQ-features?
- will it cost less than a new car?

What's under the hood is pretty irrelevant to me...

 

one more question:
- would one need a nome-made fusion reactor to feed the beast and its cooler?

 

Anyone with nearly 3k posts at B3D who can say that either 1) Doesn't know themselves very well or 2) Their Delorean broke down here some years ago and they haven't been able to fix the flux capacitor.

 

1. Depends.
2. Yes and no.
3. Definitely.

Gotta love that "8k" guess of theirs.

Somewhere, I believe I saw a post from someone confirming that Macci was on his way to Ibiza. . .

Edit: Btw, if you stitch together two of those pics for the promo board behind them, it seems to say "Future Technology Avaliable Now".

 

You forgot "...is fed up with stupid rumors and waits for some actual facts without wearing his nerves with same speculations over and over again".

And still, what it comes down to is the user experience. In that case, I wouldn't care if there's a steam engine underneath or some alien technology. It has to deliver, that's where it lives or dies

EDIT:
Btw, it would be about 5k posts if the two non-counting forums would count...

 

Now this is what i found most interesting.
Taking a closer look at the second line:

215RFNBKA15FG -> 1 respin and 5 metal changes ? Looks like the ASIC that HKEPC had back then was quite old and assumingly still had the famous soft-ground issue.

On the contrary, why does it indicate 1 respin, when actual common knowledge leads to at least 2 respins. Silicon change ?
Maybe i´m just reading it wrong, feel free to correct me on this.

 

Eeeeenteresting, thank you!

 

i think it's 5 respins and 1 metal layer change. r300 was a13 and r420 was a11
