So I see lots of people arguing over the fact that PC is more powerful, PS4 has more ram than Xbox One, but Xbox one has better Ram, but graphic cards are evolving etc...

Ruling out the Wii U that is indeed already obsolete and barely as powerful as a Xbox 360 or 2 year old graphic cards...I feel this debate has no relevance anymore.

------
Think about it (if you know some thing about graphic card) :
The GTX Titan is expensive but not that better than the 780 which is not that better than the 770 which is not that better than the 680 etc...

This is as stupid as the Mhz/Ghz race of PCs or the megapixel race of Cameras a few years ago...
And what makes the beautiful games we see on PC, no matter the mods, the settings or sample output, are mainly engine like Cry3, Frost2, Un4...and the way they're used.

Also all these Engines are compatible with next-gen consoles, and there's not doubt the next iteration will be made so too. In fact maybe that's why some typically console developers like Square-Enix, Quantic Dream, Kojima Production or Naughty Dog developed their own engines which will no doubt evolve too.

Okay I'm going to give out the futur answer I got from a Siggraph nominee this year : the future is about a completely new approach to computer graphics and engines that is not much related to hardware.

Look at this video : www.youtube.com/watch?v=pXZ33YoKu9w
and some of you will understand what I mean

Hey wait a minute, Brigade engine... is it the same guys from a couple of years ago who made big controversy by claiming they had a new rendering tech that could generate almost infinite worlds?

They released a video in a very early stage, it had a bunch of ugly palm trees, and people questioned them and even called them a hoax. Even John Carmack made a comment.

While the average consumer is happy with the power and graphics coming out of phone and are just looking for fun game experiences its nice to see that a small core only want to see the best of the best and financially destructing that side of the industry.. I also want to see the reflection of my character in the sunglasses he is wearing while looking at a shiny car across the street reflected by the door window my character is standing in front of it. Cause that will improve my fun..

Path tracing is nothing new, hardware is finally getting powerful enough to do it real time. Yes you do need a powerful graphics card to do path tracing, Brigade runs on NVIDIA's CUDA architecture.

And no it will not financially ruin the industry, it will makes games far easier to make. No more need for pre-baked lighting, pre-calculated fog / reflections, pre-baked shadows and what not. It will help immersion immensely, shine a flashlight and see it get reflected of windows, metal surfaces, refracted by water etc. Realistic shadows and changes in light to announce movement. The last of us with path tracing would look awesome.

I think this is more relevant to the future of gaming and computers as we know it...

How can you start with a sentence like this?

The Titan gives aprox. 10-15% better performance than a GTX 780 which in turn is about 30-35% better than the GTX770/680. And you call that "not that better"? And let's not forget that you are comparing them to the GTX680, which is already a lot more powerful than the chips found in either the PS4 or the X1.

Are engines important? Of course they are! But the more powerful the hardware is, the easier it is for the hardware to handle the engine, giving us better performance in the form of higher frames per second, higher resolution, better effects or a combination of all of those things, which will make games look better.

You lost me at "WiiU is barely as powerful as the Xbox360". Such nonsense...

Fun? Gaming is serious businezz.

This

GTX Titans are off casts from the bad Tesla K20X dies from the Oakridge supercomputer. A K20X goes for $3000+ which is why Titans are so expensive even if they are binned dies, are so expensive.

GTX 700 GPUs are the same architecture as GTX 600, GTX 770 is a slightly higher clocked version of the GTX 680 and on the same node so being slightly faster is to be expected. Don't worry Maxwell is coming next year and that will offer much better performance and new features.

Brigade engine is nice but won't be viable for actual AAA games for many years and will require much more powerful GPUs than anything available today. And fun fact Brigade engine runs twice as fast on a Titan than a GTX 680, even then you would need 2 Titans to get even passable performance on complex scenes at 1080p even with the horrible hacks that the brigade engine uses just to be able to run on todays hardware.
