I still vouch for the developers and how they utilize the potential of either hardware down the road.

They will surely prove to be somewhat equal when it comes to performances.

Maybe you should make sure Microsoft's PR division get's hold of this article though. It's a lot better than any publicity I have heard since the announcement of Xbone.

Steam kind of model doesn't help developers much to get profits. PC's having >100 million install base but hardly any game is selling over 5 million in PC for third parties, but consoles can sell more in less install base with higher price, so developer can earn profits and will try to riks to create more games. Also, we don't get AAA exclusive games in PC like we do in Consoles. You know why Console games are higher since the console manufacturers invested more money in making that hardware and also they invest more money in making exclusvive games with their first party studios where steam don't has these kind of problems.

Steam is great for indie games but bad for AAA title developers.

EDIT: Wrong tab

To be precise one of the killzone slides shows  4736MB or 4.625GB  of total ram usage. So we must think it's at least minimum 5GB usable for PS4 games.

1536MB + 128MB + 3072MB = 4736MB or (more than) 4.6GB ram used in the killzone demo. This 4.5GB used by killzone SF is a myth, it has never been the case, people just never properly added the numbers, they just rounded it down to 4.5GB for their own purposes. You should modify your post accordingly.

I stopped reading when I briefly saw that he combined the speed of esRAM and DDR3 RAM. It really does not work that way. You can find large articles on the internet though if you want a better comprehension computer developing and RAM

Yep, Carmack was correct. The the PS4 will essentially be the same in most respects but have the edge in frame rate. Once again Sony will show with the exclusives the difference between their machine and Microsoft's. Its not that tough to see really, but these guys are pushing it.

Do you have verified solid links to back up those claims?
Last I checked the PC has the most expensive game ever created. (StarWars the old Republic with it's 200+ million dollar budget.)

That wouldn't have been greenlighted if there wasn't a business case for it.
League of Legends has 30+ million players.

StarCraft is a massive E-Sport in South korea with dedicated TV channels to tournaments.

PC gamers have also given $15 Million bucks to Star Citizens development.

Half Life 2 has sold what, 15 million copies?
Diablo 3 sold a good 12+ million Copies.
The Sims is one of the biggest selling franchises of all time with 150 million total units moved.
Minecraft has shifted 12+ million units.

You can't forget either, often a decade old game might hit a sale on Steam and shift thousands of more units, generally on a console such games fall into obscurity never to be heard of again, thus PC games typically have much much much longer legs.
Heck, take Arma 2, years old, then a mod called DayZ came along and overnight Arma 2 shifted Millions of units, it actually sold better because of that Mod than it did on release!

Lets not forget the kickstarter revolution that is being undertaken either bringing with it lots of new PC exclusives, where the gamers vote with their wallets for the games they want, not what the Publishers want us to have.

Plus Valve stated in the past (And Developers!) that having sales actually increases profits. Go figure, thus Steam's model is *very* profitable.

Holy crap! Why do you make a thread about some random ign user's blog? Did you write it perhaps?

Its full of shit and here is why:

1. The OS ram reservation story for PS4 is false, it was debunked by devs like Brian Provinciano

2. He multiplies xbones ddr3 ram with esram(lol) like its simple math and comes to the conclusion that all of the xbone ram is faster

3. Acts like Xbones gpu boost is of significance (clocked only 53 mhz higher)

4. ''If a few extra GCN's in the PS4 are all the advantage it has, then it's time for people to stop acting like the PS4 is a vastly more powerful system.'' LOL that few extra GCN amounts to s 1.84TFLOP gpu, still 500GFLOP more than the Xbone. Its of little importance to this idiot, the huge upgrade of 53mhz to the xbone gpu is more significant

Please stop posting fanboy shit from other sites

DDR3 ram is crap. Even my mid-range laptop has DDR5 Ram. Thats like saying an i5 processor is equivalent to an i7.
