Looks like the highest power draw (from the table) is 209 Watts during gameplay. That's still ridiculously low compared to the PSU. Wonder what they were thinking in that regard.

Couldn't tell you.  My guess is they wanted enough overhead to handle power spikes,

No, that is basic foresight. If you look at the efficiency vs load curve of any PC power supply, you will see that they all have maximum efficiency between 40%-60% of maximum output. Basically around half maximum load, the PowerFETs operate very stable and run "cool". Not having hot FETs in a tight box like the PS3 is almost a must if you don't want to melt the plastic.

Plus... Capicators do age which reduces the efficiency in a Power Supply unit, sometimes upwards of 30% or more.
If Sony wants a console to last a decade or more, then they need to account for these things.

A high end GPU of today will not be in the PS4 of next year. A $500, 200 watt, 300 mm2 GPU is not going to happen.

If it is Northern Islands based, expect at best an HD 7770. The HD 7750 would be even more likely.


Wow, Northern Islands, since when did we see them entering into the business?

I meant Southern Islands (the HD 7xxx series of GPUs).

Sure, on a very poor PSU.  But putting in a PSU rated for nearly 200% of your maximum power use is overboard.

The original X360 was just a 203 watt PSU when the system operates at almost the same as the PS3 (180 watts during gameplay)



The rEVOLution is not being televised

It's possible for a game to be made to run 8 million pixels remember a game like that can still run on a 1080p television so a game developer is not short changing themselves but a developer would still make the game run in that resolution if you had a tv capable of 2160p. 

Think about it wouldn't you want your next-gen games to be able to run 2160p if you had a 2160p tv.

I think 2160p compatible games will be on the market by 2015 2016 just three years into the next-gen like I said before get ready for the eye candy.

By the way the first 2160p tvs will be hitting the market in either 2013 or 2014. Start saving your pennies, LOL.

There is no market for 2160p TV's.   What content will be provided for them?  Just the PS4?   There is no 2160p broadcasting coming online in 3-4 years, there are no 2160p movie mediums in development for the next 3-4 years.....

You don't just make a 2160p capable TV for no reason when content for that resolution doesn't and won't exist for another decade or two.  Will some 2160p panels exist on the market in a few years?  Sure, but they will be extremely niche with practically no content.

We went for decades between color broadcasting and HD broadcasting.   Expecting the industries to spent another trillion dollars to upgrade all their equipment and software to handle 2160p just a few years after already spending a trillion dollars to upgrade everything to HD is nuts.

2160p tvs are not going to come to the market and no content will follow that

Imagine the clarity you currently get from a 24 monitor with a pc game in high definition

now you will get that clarity and sharpness on a 2160p tv at 40 and 50 inches.

Currently no one is broadcasting content beyond 720p. (prove me wrong)

But there are 1080p bluray movies and a few games running in 1080p

I am not talking about over the air broadcast just movies and videogames

I believe by 2015 we will start to see the beginning of movies and games taking advantage of 2160p tvs

extreme niche with practically no content. I think not.

I stick with what I say if you want to enjoy all that content start saving your pennies

you guys think what you want to think, I am sticking with what I believe.

I've watched a few programmes on freeview HD that are 1080p, though the vast majority are 720 their are several that are in 1080p/i, especially wildlife programmes.

It cost the industry a trillion dollars to upgrade their hardware and software to enable HD recording, editing, storage and broadcasting.   Do you really think they are ready to spend another trillion or two to do that all over again already?

Do you think that the broadcast airwaves can even handle 2160p resolution?  Consider that the majority don't even operate in 1080p yet (720p or 1080i).
Cable?  Go look up their bandwidth increases since offering HD movies.   Now up that bandwidth by 4 and see if they are OK with that.  Worse still is that most are locked into a 19Mbps with MPEG-2 compression.   Good luck getting them to move up to AVC and 76 Mbps video feeds.

What movie medium will you get your 2160p movies on?  A 2160p capable movie format does not exist nor is one in  the works.

1 hour of uncompressed 1080p video requires about 559.87 GB's of storage.  1 hour of uncompressed 2160p video requires about 1.72 TB's of storage.
2 hour high bit rate Blu-ray movie is about 48 GB's.  That would make it about 180 GB's for 2160p.

For the final time I AM NOT TALKING ABOUT BROADCASTING.

I am talking about Games and Movies ONLY.

Bluray technology can go beyond 50 gigabytes.

Blu-ray Disc (official abbreviation BD) is an optical disc storage medium designed to supersede the DVD format. The plastic disc is 120 mm in diameter and 1.2 mm thick, the same size as DVDs and CDs. Blu-ray Discs contain 25 GB[ambiguous] per layer, with dual layer discs (50 GB) being the norm for feature-length video discs. Triple layer discs (100 GB) and quadruple layers (128 GB) are available for BD-XL re-writer drives.[2]

The major application of Blu-ray Discs is as a medium for video material such as feature films.

So you are telling me that a triple layer bluray disc can't run a 2160p movie, not to mention that 4x resolution doesn't necessary mean 4x more disc space.

and for games the possibilites are even more possible because games take up less space than video.

Like I have been saying start saving your pennies if you want to have all that eye candy.

I don't think you understand integrated the industries are.   First, TV manufacturers are not going to release a whole line of 'affordable' 2160p TV's just because gamers want them.

Second, Triple layer Blu-ray discs cannot handle 2160p content without a compression scheme that negates the video quality advantage of Blu-ray. 

Thrid, The movie industry is not going to back another physical movie median just a few years after already upgrading everything for 1080p.  Especially wne content is moving into the digital space.
