THIS IS ME WHILE READING DF ARTICLE:
PLAYSTATION 4 is a great console that will host amazing 1080p games and incredible 720p games!
They went with 8 jaguar cores - great! One of them is more efficient than than one PPU of CELL. It will be somewhere in the ~10x PS3 CPU range [without SPE-s].
They went with downclocked variant of 7970m - great! I expected something from Pitcarin line, and instead of going with desktop 78xx, they went with more efficient mobile version. 1.84 TF is good, but I expected better. At least, cooling will be easier with sub <2TF GPU section. ~10x PS3 GPU
They went with 4 GB of GDDR5 - awesome! This is the killer feature of PS4. It has the more powerfull GPU than Durango, but the fast memory will ensure that GPU can use all that power on the maximum ammount of data avaiable. More than 3GB of RAM data can be accessed by GPU during one frame of 60fps game! More ram access = more effect per pixel. More AA, more pixel shaders, more stuff Also, 512MB of ram is MORE THAN ENOUGH for console use and great news for games that will have access to 7x more ram data [and much faster one] than in PS3.
They included custom processing unit - awesome! This feature will enable untold advantages to the system, from physics processing, to advanced fluid dynamics, complex lightning calculations, to who knows what. Flops advantages that will be gained from this module are unknown, but will surely manage to produce great effects.
Entire console will use about 150W - great! I expected a little more power [and Gflops], but this way they have console that is really easy to manufacture [one APU, 8 RAM chips on motherboard, southbridge, and nothing much more] and relatively affordable to sell. I expect $350 for a SKU with small HDD, hopefully even lower if they want to produce console with 16/32GB of flash and empty HDD slot. Cooling and size od the console whould be around the size of PS3 Slim.
In the end, its a fast console, with fast gpu and AMAZINGLY fast RAM. I shudder when I think about the games that Guerilla, Santa Monica and Naughty Dog will create with this great hardware. Great times are in front of us! E3 will be epic!
