if ur talkin about the strappin on a fan, it wont get u from 475 to 515

temps isnt holding the gtx back, its voltage

 

[Polish3d]

Well that would certainly surprise the guys running at 515 with the fan mod I think


Either way the volt mod will be the real difference

my "detect optimal" shows 518 core.

 

[chinkgai]

well frackal, from your sig, it says ur running at 475

the guys that are running at 515 after the mod probably are a lot closer to that to start with

i did the mod myself...on two bfg gtx oc's

neither allowed me to get much better...maybe 5-10mhz better

temps are way better though...but thats it

do it and tell me if u yield a 40mhz gain

this is irrelevant unless you are talkin about the same thing as us (me and frackal)...are you?

 

[Killrose]

Hey Kristopher, Any NDA info that will blow us away in spite of 16pipe/600MHz info?

And a simple yes or no should keep you outa NDA trouble

Ok. I can hit higher than 475 but since perf. only goes up in stages it seems pointless until I can hit the next level to clock it at like 485 or whatever

Damn you luck out on parts :beer:

lets hope it continues, got a new 3800 x2 going in tomorrow and an lcd for my son.

Those better be some efficient as hell pipes.

I mean, I'm not saying it can't be done, but everytime in history a lower-piped card with jacked clockspeed has tried to take on a higher-piped card, the high-piper came out on top. 5800 Ultra vs 9700 Pro anyone? How about X800 Pro vs 6800GT?

If they price it right, it has a chance...but I don't see it being able to compete with the 7800GTX at all...MAYBE the 7800GT, depending on their efficiency.


I dunno....I'm not expecting fireworks.

 

[JBT]

Guys this is suppose to be a brand new architecture. If it truely is, these 16 "extreme" pipes may be much more effeicient than the X800 series cards. I guess we can only hope. I'm not it to much of a rush for getting a new card so waiting to see the performance really won't be killing me.

 

[malG]

How can it be competitive when the R520 (at 600Mhz) is making use of an inefficient design?

extremely high MHz = high heat = high power consumption

 

[phr0m]

i thought they had a 24 pipe comming out to?

Oh no no no. They claim that the design is "Super efficient" and claim it will be competitive with a 7800GTX despite it's 8 pipe deficit. So they had to crank the crap out of the core and get the fastest mem available. (Is there faster memory than 1400GDDR3?). I would also expect near to Zero headroom for o/c'ing this R520.
I would like this card to be competitive. Nothing more, nothing less.

OK. I can't see how a 16-pipe, 600 MHz core / 700 MHz GDDR3 card is going to outperform the 7800GT. I know it is all new technology ( maybe? just die-shrink and SM3 added ) and all but my x800xt PE is 90% there but the 7800GT kicks my cards a$$. That 512-bit ring bus or whatever the heck they are calling it better be good.

I think the HardOCP made a valid point in a recent 7800GT review:

We know many people get caught up in pipeline counts debate lately. The GeForce 7800 GTX does have 24 pixel pipelines and 16 ROPs, while the GeForce 7800 GT has 20 pixel pipelines. We are starting to move into a time now however where pipeline count really isn?t as important as a performance indicator as it used to be. In the past, you could simply look at the fillrate and guess the performance. With video cards today, I think we need to start moving beyond this kind of thinking and not get so caught up in the details that may sway our purchasing decisions. Definitions and architectures are changing; how a pipeline is defined is changing; and how performance is derived from fillrate is changing. We should simply look at the game play performance and image quality delivered by each card and make an informed purchase decision based on that criteria.

In other words, don't judge the card prior to its released based on pipelines alone. Wait until it's actually benchmarked before coming to any conclusions.

Likely later, when they can get production up & running more smoothly.


I'm disappointed, but this is somewhat to be expected, since we all knew ATi was having issues.

My guess is that this will compare to the 7800GTX, but of course, who wants a higher clocked card with less pipes.
I would prefer the 7800 myself, as will most people here.
I'm guessing we'll see a 24-pipe card later that will spank the 7800GTX, but it'll be too late by then.

This kinda reminds me of Intel's transition to 90nm...what a success that was :roll:

We'll see i suppose.
Looks like my next card is gonna be an nVidia though

Really big article on all things R5xx coming on the FP soon. You'll like it. We go under NDA tommorow, by the way - so this will be the last one for a few weeks :'( (maybe we can sneak some R580 info in here and there though).

Possibly, or maybe Nvidia uses inefficient pipes and Ati uses Sinsemilla in their pipes. If Ati competes it bodes well for the future revision that is rumoured to have 24 pipes.

Wait a sec, you go under NDA tomorrow? Do you mean your not under NDA now but you go under an NDA tomorrow? If that's the case then spill out as much as you can now! It's still legal!

QTF!

How long should I refresh the home page?

OK, so now I guess it's "confirmed":

At this point, I am still "meh" though I have the feeling R580 is right on the heels of R520, making it even lesser of a value at $599.

If launch is really October 5, we've still a long time to wait for benches!

Edit: And even if the XT debuts at only 10% faster than the the 7800GTX, nVidia only has to put a nail in the coffin with a $50-100 price reduction. Or release an Ultra version. Or release a .90mu version with a higher clock. Or release a new driver to get that 10%.

Once again, R520 is ATi's 6-month-overdue disappointment. Mark my words.

The 512MB memory is suprising..

Only way to justify the price tag.
