That would put this videocard at almost 300 GB/sec. If Nvidia needs such a big memory bandwidth, then it means they have one frickin fast GPU. Hope this comes out true.

:shocked: 256GB/sec per GPU is ridiculous, absurd, so much so it might actually be true. If true, NV is really gearing up the GT300 to be a monstor GPGPU with that many cores and that much accessible bandwidth.

Now I'm totally going to wait for Nvidia cards. If this comes out true, then 5870 prices will drop like a hammer after the GT300 release .

Im in the market for a new Graphics card but im thinking about waiting for one of these...

Just hope now that its not going to be a massive power hungry heat machine lol

Don't care about power hungry. I just want a stock cooler that exhausts the heat out of my case and is for the most part silent. I for one welcome a card that's actually worth a $400-$500 price point. It better equal or outperform 2x4890s though.

It makes mention of 512bit bus, with gddr5 at 1000MHz, with a latency of 0.5ns ? But, shouldn't it be 0.8ns? 512 * 4000MHz / 0.8 = 256GB. 512 * 4000MHz / 0.5 = 400GB.

I'm confused

And I doubt it's true. Look at a HD 4850 vs HD 4870. Clock the HD 4850 to 750MHz, and the only difference will be gddr3 vs gddr5. Even though the HD 4870 has double the bandwith, it doesn't even come close to double the performance. So unless a GTX285 is bandwith starved, and the GT300 will do more then double performance, I doubt double the bandwith is necesary. Then again, who knows, maybe Nvidia is actually going all out, trying to completely demolish ATI's RV870 in terms of performance.

well, this seemed to be what their previous core (G200) was gearing up to.

there is quite a lot of flexibility in the timing and clockspeeds of something like GDDR#

That would be nice if they could sell it for $400-$500. If these rumors are true I imagine it would be back up to $599-$649 like previous high end cards.

Well, gddr5 = qdr. 1000mhz would suggest 4000mhz 'effective'. 0.5ns is very damn fast, as current gddr5 = .8ns, afaik. Also, it wouldn't make much sense to go with 512bit and get 'cheap' gddr5 ram that runs at 800mhz (like the hd4770, of which the ram can still be clocked at 1000MHz almost 9 out of 10 times)

So either my math is off, or the numbers are fake/their math is off. Or they made a typo and mean .8ns instead of .5ns.

It makes sense that Nvidia would be using DDR5 if they are keeping the same 512 bit bus. Otherwise how else could they compensate for a 512 stream processor core? 1024 bit bus and GDDR3?


P.S. I also agree with you the time to buy HD5870 will be after the release of GT300?

But seriously when will anyone really need these chips for gaming? Are 2560x1600 monitors dropping in price anytime soon? Is the next generation game console about to surface ? (Therefore giving us more hardware challenging "ports").

Since they are making this card on 40nm and it will be coming out after HD5870 it may not be priced so badly.

I guess Nvidia has determined it is more efficient to make a Big Single GPU than go with X2 cards as will likely be the case with HD5870x2. (re: I've been told X2 cards waste memory chips due to the "mirroring" effect)

There will always be new, more demanding games. I don't follow this logic, at all. Sure, some HD4870 can max out pretty much any game out at the moment that matters...but it won't be able to a year from now. Would you rather they stop releasing new, faster, better graphics chips so you can't get any better graphics or performance?

I still can't play Crisis on all Very High and yes I really like the game so it is important to me.

That's true for current cards. But at some time in the hopefully not-too-distant future we'll see cards with a unified memory architecture that will allow both GPUs to access a single pool of memory. I believe there were rumors that AMD had been working on it for the R700 series, but that obviously it didn't materialize. Perhaps the R800 will see this feature.

GDDR5 actually uses the DDR trick 3 times, like DDR3. GDDR3 and GDDR4 BOTH use the DDR trick twice, like DDR2. GDDR3 and 4 use the same technology, the difference is the effective speed and power consumption. likewise it is possible to push the envelope on GDDR5.

People thought this unified memory for the R700 was Sideport which Dave Baumann answer here on why they didn't implement it. Basically inter-GPU communication improvements toward the end of the RV770 launch negated the need for such a thing (last I heard was it's still disabled in the drivers). This isn't a pooled memory interface, we are still waiting for such a thing but it was a start.

BTW didn't Lucid's Hydra boast such a thing when it was the talk of the town a while ago?

I wish they would make more PC specific games that actually needed the extra GPU power?

Once the next generation gaming consoles emerge this will definitley happen as current hardware will have more of a challenge playing the same "port" game (intended for 720p) on 1680x1050 (for example)

Honestly at the moment the Game that hurts my system the most isn't the Crysis demo but the Empire Total war demo.

Well considering There fab is having troubles with 40nm . and the fact it hasn't tapped out yet. This is maybe a good thing for all of us including NV. I doubt we well see the 300 this year. I doubt very much that the first tap out won't be the last.

I want this to happen. Not to hobble NV . But to see What ATI does with pricies when they have top card . For a very long time. If ATI/AMD don't try raising pricies. I may become AMD fanbois. Already ATI fanbois. But if card is $500+ I know a sheep in wolf clothing.

They are a publicly owned company, there better not be any sheep involved save the customers. It will be all wolf, as it should be. Those executive decision makers have a fiduciary responsibility to their shareholders that won't be ignored unless incompetence gets in the way...ala financial sector.

If thats the case. Than Since NV has more money than AMD/ATI. When NV comes back with DX11 and its all that. I would bite the bullet. and punish AMD/ATI with low pricies. But dam if NV didn't back itself into a corner with Monster sized Chip . Same as Larrabee maybe smaller maybe bigger. Right now ATI/AMD looking good chip size. Intel ?NV next chips are big and expensive but I believe Intels will get better yields. Dam AMD is looking smart buying ATI with that small chip.

For you idontcare. Check out the lastest articles on Power Vr Apple Intel . Power VR is set to bring pyhisics and raytracing to hand helds. Find Article and comment . Your much better than I at it.

Sheep in wolf clothing LOL. Try Wolf in sheep clothing. But as always you knew what I meant.

I think ATI will charge as much as they can for HD5870 but the real question is how much is a 2.1 TFLOP Video card actually worth? (based on speculation of 1200 stream processors @900 Mhz)

4850x2 is already at 2 TFLOPs.

So it might be that ATI charges $300 for HD5870?

Now if the HD5870 comes with 2 GB memory then I am sure they will charge over that. (since 4850x2 is in reality only a 1GB card and not to mention an internal crossfire one that will likely use a lot more power)

Ya its tough call. NV chip looks strong from those specs. But large. As for specs on the HD5870 LOL. Have none learned from the last time the 4000 series leaked specs. If so why were so many shocked and awed by the 4000 series. On release. ATI/AMD have learned the ART of understating. FINELY! If you keep pushing an idea long enough someone usually sees the light.

So you think HD5870 will be stronger than 1200 stream processors @ 900 Mhz?

I wouldn't doubt it myself.

Honestly 1200 stream processors @ 900 Mhz sounds pretty modest considering HD4770 is already 640 stream processor @ 750 Mhz and HD4890 is 800 SP @ 850 Mhz.

Well from 800 to 1200, we have a 50% increase in shaders, so I wouldn't see it "modest" at all. Add 100% more ropes and we have something there. AMD needs to cranck up GDDR5 though. We've already seen how much memory bandwidth starved is 4890 with the GPU clocked at 900+, so I would imagine that 5870 needs a hell more to run fast.
