Major reports discussing the next-generation PlayStation from Sony have surfaced over the past few days and one in particular goes into some significant detail when it comes to what the system will feature.
According to a report from GamesIndustry on Friday, the PlayStation 4's AMD Jaguar tech will be a space sensitive device as each core takes up just 3.1mm2 of die-space at the 28nm fabrication standard.
When you take the L2 cache into consideration, the overall CPU could end up being as small as 75-80mm2 total. All of that is in contrast to the PlayStation 3's cell processor that was about 235mm2, with the PlayStation 2's processor size checking in at 240mm2.
So given the eight core setup for this next PlayStation, there will still be plenty of space available to integrate the main GPU on the same die. This means that the cost savings will be much higher and the overall power consumption will decrease.
PlayStation 4 eliminates a couple compute units that are made together, which ends up dropping around six percent of the device's overall clock speed. It's easy to see the unit producing no more than 150W when the overall components of RAM, CPU and storage power draw are factored in.
This bodes well for the PlayStation 4 using less power than the PlayStation 3 and Xbox 360 do. Those systems consume about 200W of power, so it's a 25% decrease for the PS4.
Some hard evidence of the PlayStation 4's memory setup was also presented as it will feature 4GB of the GDDR5 with 512MB reserved for the console's operating system. The GDDR5 RAM is the extremely fast RAM that typically is implemented and shipped with the latest PC cards.
