1GB wtf

[keith33]

1GB, HOLY TITS! You should be able to get by with a gig of ram these days then if your video card can hold a gig of textures. That's insane.

[Nvidiot222]

Holly Molly :o!!!

[CaptNKILL]

Im going to cry...

There are so many different rumors, and I know Im buying one of these... why cant we get some straight info? :(

[Uberpwnage]

Umm, everybody seems to be distracted by the 1GB vram, but what about the jump from 1600MHz mem to 2000MHz? I think thats more of a "wtf" then the GB. I think this only means that if nvidia wanted to, they could put a gig into it, cuz they are doing that with a quadro based on g71 core. We have NO NEED for a gig of video memory anyway, besides it would cost $xxxx like the quadro. 512MB just became the new high end standard, and a jump this fast is unrealistic IMO.

LMAO!!11 they just claimed that the 2GHz was incorrect...and put it back at 1.6

[saturnotaku]

Because MikeC has not deemed it that us mere mortals know. Wait, wrong thread. :p

I agree.

2ghz memory would be sweet too, but I really doubt we'll see it on this card. And a card with 1 gig of it just plain isnt going to happen.

Epic at one time told their GEARs of WArs game will need 1GB ram in your video card for their "ultra highest quality" settings.i guess is similar to the Doom3 "ultra quality" mode ,but with higher memory req.Of course that was told much earlier (~a year ago) before any announcement of the Xbox360 exclusive time launch.

Well it seem 1GB rumour is true, yes G71 is designed to supported 1GB (http://theinquirer.net/?article=29469), Nvidia's premium customers been asked Nvidia to added 1GB on G70 Quadro but they couldnt do it on 110nm, they have to do it on G71's 90nm.

I think it is possible here will be 2 versions of G71 with 24 and 32 pipelines, a 512Mb 24 pipelines 7900 GTX retail for $499 to replace 7800 GTX 256 and 1GB 32 pipelines 7900 GTX to retail for $799 to replace the flagship 7800 GTX 512.

When exactly is GoW to be released? And 1GB? WTF!?!? the 360 has only 512MB that it shares for then entire system lol. Well if it does need a gig to look its best then i guess thats when pc superiority over consoles begins again lol. Of course you did say it was old news so maybe they toned it down a bit.

[slick]

Bear in mind console game engines are much more efficient than PC game engines. 512MB is a LOT for consoles to be able to work with.

[jAkUp]

Memory is memory, my guess is that GoW will have higher texture resolutions for the PC.

Also, I know that the O.S. takes up some system memory, but how about graphic card memory? I would imagine that it has a small footprint as far as graphic memory goes.

It's been a long while since I checked, but I'm fairly certain the OS video wise (XP mind, this'll definitely go up in Vista) sits in about 2-4 megs of VRAM (it's only a very small number of 2D textures). You can check though - use Rivatuner's Video-memory monitoring plugin, and you can see how much VRAM is in use at any given time.

With that said, if a game is running in full-screen mode, there's no reason you couldn't just empty the VRAM totally and use it only for in-game stuff. I mean... it's not like you need the start bar texture when you're playing a game.

Oh, and as for "Console engines are a lot more efficient" - yes, that's true, but Jak is right, VRAM is (basically) VRAM. You can stream data in and out of memory to some extent, but if texture resolutions get too high, there's only so much you can do to get around thrashing to disk (or main memory, as is more frequently the case on PC) to load in textures. Do bear in mind, lastly, that you still have to access these textures. Just because you've got a massive amount of very fast memory, doesn't mean that your bandwidth problem is solved. I'd be very surprised if even a 7900GTX could get much more use out of a gig of memory than it can from a half gig, unless they bite the bullet and move to the expensive option of a 512 bit on card bus.

Still - I'm no expert on Graphics cards, so all my guesswork might be wrong!

Nice... :)

[Mr_LoL]

If it is going to have a mrsp of $500 :drooling: I will be buying one. Thats about £350 for us folks in the UK. Cant wait.

[Monnie Rock]

why is the memory slower on the 7900GTX than the 7800GTX 512?

[agentkay]

Lower price and higher availability of the card. At least thats my guess.

[kam03]

im going to upgrade when these ram are implemented on graphics cards:

Samsung Electronics, the world’s largest maker of memory, announced that it had developed GDDR4 memory chips that can operate at speed of 3.20GHz, nearly two times higher compared to memory frequency on today’s graphics cards.

“With such phenomenal processing speed, we’re able to offer video card manufacturers the bandwidth for incredibly life-like movements and richly textured imagery that will soon rival that of cinematic movies,” said Mueez Deen, marketing director, graphics memory and mobile DRAM, Samsung Semiconductor.

The GDDR4 memory chips with 0.6ns access time capable of working at 3.20GHz resulting frequency are made using 80nm process technology and have 512Mb capacity. Late in 2005 Samsung introduced 256Mb GDDR4 chips rated to work at 2.50GHz. Voltage and heat characteristics were not touched upon by the company.

GDDR4 memory is intended for graphics sub-systems and other multimedia-oriented devices that require high-speed memory and can use point-to-point memory interconnect.

It will take some time before developers of graphics processors and their memory controllers will be able to utilize 3.20GHz memory, as GDDR4 final spec is yet to be ratified, whereas graphics chips are usually tailored for particular range of memory speeds.

Unfortunately video card prices are much more expensive in Europe including UK....

[SH64]

Hmm i cant believe the 2000Mhz/1GB VRAM story .. even if its true , that wont mean much for the performance as the XTX is super fast even when its memory is slower than the GTX512 (1650Mhz vs 1800Mhz).
1GB VRAM is overkill right now IMO.

seems what matters the most right now for the 7900 is its core clock.

EDIT : oh i see the 2GHz memory story is incorrect now.

Yeah i see they retracted the part about the memory running @2ghz, but how much is 1GB video card gonna cost. Alot i guess

G71, 7900 GTX is eight to ten per cent faster

ASIAN partners are disappointed with the upcoming Geforce 7900 GTX cards. Most of the companies already have the samples and tested them but they are not happy with the performance. First tests indicate that in the best case scenario, Geforce 7900 GTX cards are eight to ten per cent faster than the last and rarely available Geforce 7800 GTX 512 card.

http://www.theinquirer.net/?article=29931
Geforce 7900 GT has 7800 GTX 256 performance for $299

Nvidia will price those cards at around $299 or just a little bit higher in Europe. This means that Nvidia will sell a card clocked at minimally 450 MHz core or even higher, a 256 MB card with full 24 pipelines for a price of 7800 GT. The performance of 7900 GT might be as high as 7800 GTX as the card is clocked 10 MHz higher and has the same number of pipelines.

We expect that the cards will be very overclockable as they are 90 nanometre based and there is still enough space to set the clocks even higher. We know a few companies that plan to clock those cards a little bit higher from the launch date.

Any doubt at this point about the number of pipes ? :D

[OWA]

Hmm, if that's true, I guess I won't be upgrading my SLI system even if the price is much lower than the GTX 512s were.
