I think prices are going to be higher. At least on the 770. At $400 that's pretty much going to shove the 680 down to sub $400 and cannibalize pricing on lower cost parts.

With specs like that the GTX 780 should be slower than Titan....

....which means 7970's you can buy today will still murder them.

Heck all AMD needs to do is drop the price of the 7970 and they'll eat into GTX 780 sales hard.

But I'm just speculating. Paper specs don't tell the whole story. We'll have to see when the benchmarks come.

Uh, the only thing the 7970 murders is smooth gameplay. I've played on two identical systems; one equipped with two GTX680s and one equipped with two 7970s in Crossfire and what a difference. I played BF3 and Crysis 3 at maximum settings at 2560 x 1440 resolution and can tell you now that the NVidia cards gameplay experience was far superior to the ATI cards. What most hardware reviews don't discuss into detail beyond just maximum FPS that can be achieved (yes, the ATI cards do achieve higher frame rates in some cases). The biggest difference is not max frame rates, but actual fluidness of the frame rate throughout the game. NVidia cards achieved a higher lowest frame rate in both games, but lower highest frame rates. So what this equated to was a smoother gameplay experience without any choppiness. I noticed considerable choppiness with the 7970 Crossfire setup, whereas the GTX680 SLI configuration played games extremely smooth. Do yourself a favor and do some homework next time before trolling.

Looks like I'm skipping the 700 series, selling my 2gb 680 and getting two 4gb 670's. IMO if these specs are true then a overclocked 680 could play in the same court as this :(

Wow. Their whole lineup is a mess...

If you think games can use all 8gb ram on the ps4/xbox then you are wrong because they wont.

there is an OS and all the share crap they have that takes a nice chunk of that ram away at all times.

the ps3 and xbox do not use all 512mb ram either.

Also PC DRR3 ram is way fast enough for everything except the most critical GPU features that have to be spit out as fast as possible.

Not going to fly off shelves at those prices.

Just a jab at the comments about memory... While 8GB shared between the GPU and CPU is all "lolwut"... Most games on the PC don't use more than 2GB of RAM and all graphics memory buys you is texture memory and better AA quality. Both of which don't seem to be a problem these days.

Anyway... $700-$750 for a flagship card? No thanks. I'll wait for the sweetspot $300 card. Even then I think my GTX 670 will still be viable for the next two years.

"Most games on the PC don't use more than 2GB of RAM"

That's mainly because not everyone has a 64bit OS; Windows x86 limits the memory to at most 2GB, unless you use the LARGEADDRESSAWARE linker flag, then it's 3GB.

Details here (Memory and Address Space Limits): http://msdn.microsoft.com/en-us/library/windows/desktop/aa366778(v=vs.85).aspx

If you look at the Steam Hardware Survey, you'll notice about 50% of Steam users only have 4GB of RAM available. I doubt a game would be able to use 3GB with that little available. Also, about 20% of Steam users are using x86 versions of Windows, so they can't utilize more than that anyway.

future proof is 8gb video memory. its the standard by xbox 720.

We don't know if the next xbox will have 8gb of video memory. we don't even know if it will be called the "xbox 720" or not.

PS4 packs the equivalent of an AMD 7850, and the new xbox won't be any better. So sorry, we're been past your "future proof".

avatar

devin3627

but what you didn't know is that ps4 was originally releasing 4gb until xbox had 8gb, ps4 follows microsoft. developers learned the headache of smaller system/video memory. performance isn't everything and it will be proven. just because direct x 11 and what not. FXAA has eliminated the rape of frame that antiliasing causes as an example, they realized software was the strong point and the more memory, the more software function.

How is performance not everything. Performance isn't raw specifications, which you assume that I'm arguing. PC has had DX11 for some time now, and Nvidia released TXAA format for their Kepler GPU a few months ago, which is superior to FXAA, and is quickly panning out.

What you're talking about is optimization. The reason why the now ancient xbox 360 and PS3 can run brilliant looking games is because they have a set configuration that developers can optimize the crap out of. With PC's, everyone has a different configuration.

A properly built PC will run cooler, faster, quieter, and be more cost effective than a console will at launch prices, while benefiting from a continual game library.

Sony released specs before Microsoft, and the "720" will have DDR3 8Gb, 3 of those GB will be for the OS. The PS4 will have 8GB GDDR5, which is faster.

JFcMichael,

You have absolutely no idea what the hell you're talking about!

avatar

JFcMichael

Don't I? All PC builders know that GDDR5, the memory used in graphics cards to process graphics, is faster than DDR3. The "720" has DDR3, while the PS4 has GDDR5. Both have 3GB out of 8GB of their RAM reserved for the OS, and the rest is shared resources. This was confirmed by both companies. Sure seems like I don't know what I'm talking about, doesn't it?

avatar

devin3627

JFcMichael is wrong. playstation's original plan was fast 4gb until speculation arose of xbox 720's unannounced 8gb. just because sony released first doesn't mean they decided on 8gb.

avatar

JFcMichael

And what is your source of information? Is it a trusted news site? Because I have never heard of such a bizzare thing. And if the 720' specs haven't been released yet, how did Sony get their hands on that info? How did anyone? I surely didn't hear about it, and I come to this site as well as others often.

Consoles have their system RAM in that 8GB as well, while PCs have it separately.

Nice to see GK110 trickle down to more consumers not willing to go 1k on the GPU, but it is still bloody expensive. :p

It's likely the next Xbox will have a shared memory architecture much like the 360. So that's 8GB between the CPU, and GPU.

avatar

devin3627

correct, but data and coding "behind-scenes" is vital to non-screen function. this GDDR5 has never been seen by functions on pc. thats equal pipeline straight from gpu to cpu... all developers know you have this because you have a xbox 720. xbox 720 will balance out data and code execution shared with video memory, they are practically synced. so many PCs today have bottlenecks, this has 0% trust me man, the developers have complete control and standardize graphic settings per console platform.

Shared memory is ineffective in terms of performance. By having a shared memory, the CPU and GPU are limited by the proximity to the memory. Have them too close, and you'll have heat dissipation issues. Too far and your data transfer rates slow dramatically down.

Shared memory should only really be for SoC's, which should NEVER be in a high end console.

GDDR5 has been in PC's for a while now too, in the GPU.

Any bottlenecks PC's have, consoles will have as well.
