Lots of R600 news

New Rev is A1.2 and it works with over 800MHz
Vcore is lower than 1,2v
R600 uses GDDR3 but has a bigger bandwidth than G80 = 512Bit
Shorter than 8800GTX

previous reports indicated gddr3 versions were dropped - this makes me wonder if there will be gddr3 xt and gddr4 xtx versions, or possibly even lower binned parts making use of gddr3.

Some good news for waiting fans !!

If this chip really consume only 80A @1.2V then we should get less power hungry card than X1950XTX.
Chip: 80A*1.2V=96W
Memory 1GB (16 chips) @ unknown clock: ~2W*16=32W
Other circuity: ~20W
Total: 96+32+20=148W

Remember that this is absolute maximum for chip to consume 80A, everything else is only approximation (hopefully close one ).

sexy, more than 800mhz...

[metro.cl]

hmm hard to believe, time will tell

[biohead]

they better not release same cards with either gddr3/4, one having to be 'lucky' again. like x1900 xt/xtx - u either get 1.1 or 1.2ns.

r600 & gddr3 makes no sense though :/ to me anyways

[Rovtar]

when we will se2 tests?

i want to see how good will be

Agreed, ATi FTW!

Maybe gddr4 is overkill ? lol. Its wise to be marginally faster but with alot of headroom

[Ubermann]

....

R600 DIE SIZE compared to G80 small, the transistor are more than G80

720 million transistors

Sounds more powerful then the ATI RAge+ PCI card i have in this comp right now..might even be twice as fast.

[[XC] Malkec]

r600 will smoke g80's ass big time

With 512-bit it does make sense. They obviously don't need THAT much bandwith.

R580+ was still bottlenecked by GDDR4 because of some weird clocking bug. Go figure.

[eXceeded]

But whats the point in not making the card as fast as physically possible ala GDDR4... no point in GDDR3 at all, except for budget models.

I want to see a picture of the card side by side with a 8800GTX before I'll believe it's shorter.

It may not increase performance enough? GDDR3 is cheaper, so it might be stupid idea for them to have lower profits without speed increase at all or with marginally little increase.

I got 1.1ns memory on my XT yet it can't handle XTX speeds I got dud memory I guess.

I like the sound of this R600 Too bad my income allows for almost no upgrades.

[xs64]

i wanna tell a little thing about DDR3 and DDR4

I have 1 X1900XT and 1 X1950XTX
I oced my X1900XT @ 650/720 and keep my X1950XTX at DF

Guess what , in NFS Carbon ( using Fraps ) i got 41 pfs with my X1900XT and 64 fps with my X1950XTX

So i love DDR4 !!!!

Simple, they have to leave room to grow.

Both NVidia and ATi are banking on their new architectures to last a few years. Kind of like how the R300 architecture lasted ATi from the 9700pro to the x850xtpe, or how the nv40 architecture lasted nvidia from the 6800ultra to the 7950gx2.

If you have to keep making new designs because you went all out on your new chip, you're essentially shooting yourself in the foot, as that makes your profits on the architecture that much smaller. An obvious example is that the R520 architecture wasn't nearly as profitable as the R300, as it lasted them only about a year, while NVidia's NV40 architecture made them huge amounts of cash because it lasted them well through 2 years.

NVidia left themselves plenty of room to grow with the G80, from die-shrinks to upping the memory bus to faster memory. ATi need to give themselves that same headroom, and if ATi start with a 512bit memory bus and 80nm, the only way to refresh will be faster ram. 65nm won't be ready for chips this complex at TSMC in time to compete with NVidia's refresh.

Think business, they have to give themselves a cheap easy way to refresh the cards, and I can't think of anything cheaper than a pin to pin compatible memory switch. They can keep the same pcb, same cores, and merely update the ram like they did with the x1900xtx-x1950xtx and go right back to charging top-dollar for it again.

It may just be lower binned 1.1's

[Cuthalu]

xs64, its GDR, and those cards are not R600 and they have only 256-bit memory interface.

G80 uses GDR3 and 320/384-bit memory and it isn't very bandwith-dependant, and R600 with it's 512-bit would have even more bandwith than G80.

I am wondering, if this card really is suppose to be SHORTER and require LESS power than the 8800GTX does that mean it will only require ONE PCIE power connector or are we still going to need two? The 8800GTS runs fine on one native and currently available PCIE power connector which makes for a very easy video card upgrade if you don't have to get a new PSU to go with it. There was rumours of the R600 possibly needing a new type of power connector to deal with the new power requirements though it seems this may no longer be necessary. I would love to keep my current power supply in my sig (Powerstream 600w) if the new card truly will use LESS power than the X1950XTX which my system currently runs an equivelant to (X1900XTX overclocked) without issue. I was JUST about to order a GTS tomorrow thinking the R600 would be too long for my case and require a new PSU to power it which made things real expensive and full of hassles. Perhaps I will just hold off now to see how the ATI offering holds up as it just may be better.

I bought an Enermax Galaxy 1000w and it comes with an 8 pin pci-e connection. In the manual it says "for upcoming generation of cards"

[Steensen]

Sounds interesting.
Would be nice that the R600 can do with the current 6-pin PC-E plug + PCI-E slot, but yet againg, 148W is too close to the standard, for the producers being able to balance the load correct.

Enermax Galaxy 1000W and 8Pin PCI-E connection Do you sure that ?
