So the 800 will be the most milked series ever. I can already see it ; 850, 850ti, 860, 860ti, 870 , 870ti, 880, 880ti, 885, 885ti, 890, and multiple version of the titan series tongue.gif. Oh and each card will of course bring a 2, 4, or 6gb version.

With that said... can't wait for the big daddy of maxwell.
you forgot the TiTi version of each card tongue.gif 880TiTi xD

Seems like every even number starts the ball rolling and the odd nuber series is where they get things locked down before the next latest and greatest chip is release.
yep thats the card people should go. the 6gb 780 will be like ultimate long term cards

With all the hype nvidia put into 4k I bet they'll do a 512 bit bus just to appeal to the "bigger specs number means bigger performance" crowd.

I hope you're right because I’m a card carrying member of that crowd but I can’t help but feel that cutting features for the sake of “good enough” performance is going to win out in the nv board rooms because it's more profitable.

I thought the bus speed effects the memery. I still have a lot to learn...

How big is the cache on a GPU?

Shader power isn't everything.

40 ROPs is pretty low, but more than I would expect for the mid-range part. We'll probably see 48-64 ROPs on big Maxwell.

Bus width isn't the same as bandwidth, and nothing about a 4GiB buffer demands extreme bandwidth to be useful.

It's true, that with current and past titles, that to utilize a 4GiB texture/frame buffer you would need to run at settings most cards equipped with 256-bit memory buses could not handle well. However, the trend people have of linking the two, absent reason, needs to stop. It just leads to foolishly incorrect assumptions.

If a game has a lot of high res textures, or if multi-GPU solutions are used, that large buffer will come in very handy, even on mid-range parts.

GDDR5 does provide more bandwidth at the same bus width as previous standards. It's effective clock speed is higher.

It's cheaper. Smaller memory controller = smaller die. Less memory channels = less PCB traces.

256-bit is perfectly sufficient for a mid-range to upper-mid range part.

For conventional AA types (MSAA, SSAA, and their derivatives)? Fill rate (ROP count * clock speed) and memory bandwidth (memory bus width * clock speed), are the largest factors.

For post-processing AA (MLAA, FXAA, SMAA, etc)? Shader performance is the prime factor.

That said there's two things that aren't being said here:

1) There seems to be a price listed in that table which is quite silly. Prices of GPUs are up in the air until the last couple of weeks before launch.

2) This comes from OBR. OBR might have a good record with Bulldozer but he has an absolutely terrible record with anything related to Nvidia GPUs. He's the guy who was passing around photoshopped versions of random chips calling them GK114, or some random ccard with IHS calling it GK100...

Grain of salt...

Agreed. That price, most especially, does not seem reasonable for a non-flagship part.

Bus width does affect memory bandwidth, but it's one component of it, and even theoretical memory bandwidth figures say little about the whole memory sub-systems.

GPUs typically have very small caches. I think the 750ti had 2MiB of L2. Kepler only had 256KiB.

Yes... Super fake. If this rumor had any weight they would have hinted at least the die size. Like, they know how many transistors there is inside even the vram capacity but not the die size? Why?

So now we gotta wait for the 880 Super Kingpin SC OC Ti Black Edition Z?

But first we have to wait for the 880 SCC Mini-Ti X edition first to come out, before the next big boy is released...

Good catch. It looks like they took some specs from the from the 780ti matrix but the one's they didn't have they copy/pasted from the 780(non-ti)
