I have to say I am more interested in the GDC presentation then people trying to defend the PS4 tech. Lets be honest as far as tech is concerned there is really nothing to argue about as we all know where the PS4 hardware is compared with existing PC tech.

I believe the real interesting story is that NVIDIA is try to position their cloud based solution as an alternative to console gaming and I think that is a much worthy topic to talk about.

one of the problems I have with articles like this is that things are taken out of context.  Just taking the graph without knowing what the presentation is in relation to makes it hard to form a good opinion on the subject

Seriously since when nvidia call nex Xbox Xbox 720 to be honest Sony loyality boys do try to make ps4 looks more powerful than new Xbox 

The majority of the rumors have been suggesting it but they are just rumors though

The hell nVidia? You're not joining the Nintendo-dissing bandwagon too? Maybe you just forgot, let me help you...

Now seriously, while Titan is stupidly powerful and the TRUE next generation in graphics, it's not an important player right now. Next year will get those, when GPUs with that kind of power appear at more affordable prices.

It is a official nVidia slide... so nVidia is upset with the new generation.

I don't get why Nvidia is so upset by this, they couldn't offer a system on a chip design so it's their own fault.

I don't know too but I think it is because the money lost with each console sold... at least in this generation they have the PS3... now nothing.

That is the third direct attack from nVidia to the next-generation in less than one week.

I think they are getting scared, they must realize that since alot of PC games are very similiar to their console counterparts that AMD will have a advantage on the PC graphics card market aswell.

Mostly though i think the chart shows are very wrong image, since the top notch graphics cards these days are simply way to power hungry. Just to compare a Geforce 7800 GTX hade a peak power consumption of 80W and that was the top dog back in the day(and a similair design was used in the Ps3). A titan Gpu has a peak consumption of 260W(!). It's like using 3 7800 GTX cards in SLI. And that's why i think AMD did a incredible job by creating such a powerfull APU, since the GPU of the PS4 will like have a slightly higer power consumption than the RSX in the PS3.

Steam Box would sell horribly no matter how they try and do it. 

Completely wrong.

7800GTX easily gobbled up 250w+ during peak load.

All top end graphics cards for the past 5 years or so have had a power consumption of between 200-300w give or take a few watts. The power requirments haven't gone up, the manufacturing process has shurnk which reduces power consumption but transistor count has increased (obviously) which increases power consumption, they work to a target peak and the Titan is nowhere abnormal relative to it's power.

It basically offers 50% performance increase for nowhere near 50% increased power consumption Vs say a crossfire/SLI design which eats 100% more power for basically 60-65% increase in performance.

Of course with crossfire/SLI you get good old microstutter making it worthless.

The Gefore TiTAN is nothing short of a marvel in terms of performance and power, to say otherwise is extremely ignorant and shows a complete lack knowledge of where things are currently. AMD doesn't have anything ready to compete with it and won't do for about 6-12 months!

...Now the price, that's something entirely different, that's not good at all and stinks of a cash in.

Also, the power consumption in the PS4 being similar to the PS3 is completely expected, as outlined already, the die process shrinks, the transistor count increases, each balancing out to reach a power envelope that is manaeable. AMD have done well with their low end - mid-range APUs, but don't be fooled there's nothing special going on here, top end parts still have massive power draws from both AMD and nVidia.

And rightly so, because if they didn't, they wouldn't be maximizing the design to it's limits. Which is what the PC graphics card industry is all about and these days the console graphics card solutions - are the PC solutions. AMD low power APUs = PS4/Xbox 720. These are not high end parts, the important thing to remember as well is that performance Vs power consumption doesn't follow a linear increase, when you get to the top end the "performance per watt" decreases and plateaus off as expected and as all components in the electronic industry do.

Low power designs are optimized for low power consumption (obviously), high power designs are optimized for high power with little regard for power consumption (obviously).
