ATI 4 series delayed

[Squall-Leonhart]

actually, nvidia said they had a gpu on the way that could hit Terraflops,.. they never said it was any of the currently released parts.

nvidia said that before g80 was released,

g80 didn't hit the teraflop mark

....and neither does the gt200

so to recap, nvidia said 2 years ago they had teraflop gpus,
and even still, the unreleased high end still doesn't meet it

[Squall-Leonhart]

you guys don't realise that nvidia has hardware in virtualisation testing up to 4 years before it sgets released.

[John Aiton]

well yeah, but claiming to have hardware of a certain speed implies it's going to be released at some point


the 4870 pulls 1 teraflop, the gt280 is around 933 g/flops iirc

That's obvious, but making claims 2 years earlier and then pulling the "well, we never said WHEN we were gonna release it" is just way too easy to do.

It was all simply a big marketing ploy, either that or the guys at Nvidia were seriously oblivious to what the reaction of gamers to that claim would be.

I don't think anyone is saying "Nvidia can't reach the 1teraflop". It's simply a "yeah they can reach it, but talking about it since 2 years ago was simply a marketing ploy to keep people interested".

(people could make many claims all the time, and simply say "yeah, but we're not specifying WHEN we're releasing it..." to get out of it)

Note : 1 Tera. Now THAT'S gonna be self-loving worthy for epeen masters.

[John Aiton]

Thanakil gets it,

nvidia can't meet it's old claims 2 architectures on
even ati have done it with a slower card :/

[Squall-Leonhart]

i have no doubt that with 240 pipelines, 1 terraflop is achievable. (remember, those are INDIVIDUALLY clocked pipelines)

[John Aiton]

nvidia's yields are low

the clockspeed was reduced from those projected for the gt280

the original clocks gave over 1T, but the new ones are sub 1T

sure you could overclock and hit the terraflop
but at around 300w on load? :eek:

Is there anyone who cares more about teraflops than about either Min/Max/AVG FPS in games or FPS/€? I understand it's a great prestigious landmark, but unless it translates into extra FPS directly the only people who will have good use of these numbers are marketeers.

Anyway John, I just read some more info about the 4850, which will very likely be my next card as well:

We’ve reported that the core speed of RV770Pro graphics chip can be reached at 990MHz (The core speed of RV770 Pro now can be reached 990MHz-GPU,CPU,Video Card,Motherboards,IT,News,Review,Preview,Game). But now AMD set the speed of retail version of RV770pro at 625MHz. AIB graphics cards marker told us this is the marketing strategy, in order to get the performance difference between RV770Pro、RV770XT and HD3870.

According to the AMD's reference design manual seen by AIB graphics cards markers, RV770Pro design frequency went beyond 900 MHz, that is when RV770Pro run in the 900 MHz frequency is only when the frequency of its design, and the 625 MHz frequency is obviously down to use.

Considering the Power play function and energy-saving features integrated in RV770Pro, so in some cases the core speed of Radeon HD 4850 will be even lower than the frequency of 400 MHz.

The only thing I fear for is that they have undervolted this card as well, which wouldn't surprise me given the lower power requirement and lower production of heat. Of course this card will become a modder's / OCer's favourite, and I'll be giving it a shot as well. I just wish it would come with a double slot cooler.

cool, btw Toms hardware have sized up the performance of the 4 series and it looks nice

[Cid Highwind]

That's just ATi's own slides being leaked, just look at the AMD logo in the top right corner on the other slides.

This one is interesting though, seeing how they allow partners to release 1GB versions of the cards in the future. No GDDR5 Pro cards though as I had hoped in the beginning.

[Cheesus]

Basically that chart just said that no single core offering is going to beat the 8800Ultra from AMD's side. Yay :/

[John Aiton]

the rv770xt will wipe the floor with an 8800ultra

the only reason the ultra still bests everything is bandwidth related,
like uber high res with AA and AF settings

the gddr5 will produce more bandwith than the ultra had and the gpu itself will be faster

remember the 9800gtx is a die-shrunk g80 with a higher clock,
that's why it easily beats the ultra in most situations

but when the res is upped the g80 has higher bandwith and wins,
if the 9800gtx wasn't 256bit limited then it wouldn't lose anywhere to the ultra

I have read the same article, the 4850 is pretty much an underclocked 4870 just to fill the price gap. They also didn't allow other Brands to sell a overclocked version.

[Cid Highwind]

Yup, now let's just hope that there's either brands that slap on a better (dual slot?) cooler, or a decent aftermarket cooler that fits on this card. I would definitely settle for slapping on an Accelero2 myself. Who needs factory overclocked cards when there's ATi Tray Tools?

two 4870s should make for a KILLER gaming setup

I would hope so. It would be great for ATI to regain the throne of the very high end range.

But I'm going to hold my breath, and see how the drivers and OpenGL support are, in regards to purchasing one or 2 of those cards for myself.

sorry, but from what I've heard the gt280 is about 20-30% faster than the gx2

and from ATIs own personal graphs, the 4870 is slower than the gx2

[Cid Highwind]

Yup, but that's not so surprising, seeing how they aim to go for a good bang for buck ratio. They won't even aim for the top performing single card, still their R700 will be most interesting. It may not be the top performing card, but if it will be €150,- less expensive than nVidia's top card it may still be a bigger success than that one. It will probably be like they have the 3870X2 right now. Not the top performer, but a great value and great performance anyway. The only reason to spend more is because you've got too much cash to burn, or are a die hard nVidia fan and want nothing but the best, regardless of cost

but Aiton your flip flopping back and fort on your claims then.

First you said it was ATi's 4000 series would beat g200 series

then it changed to the 4870 was weaker than the g280 but would take the performance crown from the 9800gx2

now its changed again as you say 9800gx2 will still be more powerful in most situations then the 4870.
