Following up on their previous
updates, today Sony's SVP has given PlayStation 4 fans more insight into the PS4's noise level, power consumption, media performance and more below.
To quote from DualShockers.com (linked above): "Sony Computer Entertainment Japan and Asia Senior Vice president and Director of Business Unit 1 Masayasu Ito
isn’t as well known as Shuhei Yoshida
between PlayStation fans, but given his technical role he’s the best person to ask about some of the most technical aspects of the upcoming PS4.
Today he gaver some extremely interesting information about the console as part of an interview on the Japanese tech site http://av.watch.impress.co.jp/docs/series/rt/20130924_616515.html.
Here’s a summary of the most relevant points:
- While being always online is not necessary, a network connection is important to fully enjoy the features of the PS4.
- The PS4 will initially act as a stand-alone web server for the PlayStation App. In the future there’s the possibility of this to be expanded through the cloud, with the PS4 and PlayStation App interacting through the cloud, allowing cooperative play between multiple players.
- The secondary chip for ultra-low power operation will mostly activate at night from 1 to 4 AM and download any required update automatically. It will also activate when software is purchased through external means like the PlayStation App.
- Power consumption will vary greatly depending on the performance of the game played.
- The noise level of the console during operation is generally much lower than it was on the PS3.
- The PS4′s cooling fan has a low noise level and stepless speed control (meaning that it will increase its speed to match heat smoothly and not in sudden steps like the one on the PS3).
- Since the Blu-Ray player is 6x instead of 2x (like the one on the PS3 was), the spinning noise is actually louder. Ito-san feels it’s not annoyingly louder and it will be countered by caching data on the hard disk drive. It’ll be mostly audible during the initial spin-up.
- The Audio/Video performance (for movies and music) of the PS4 will target PS3 levels at launch, but will be improved through updates, for instance with the addition of 4K, as Sony is also an Audio/Video company.
- The theme of the PS4 is “Personalization”, meaning that it will offer an experience tailored to each individual.
There you have it: looks like quite a lot of thought has gone into making the PS4 easier on your ears (the stepless fan control is a big improvement there) and on your power consumption. We’ll have to see how this will actually work in real life, but the data provided by Ito-san is definitely interesting."
Finally, below are details on the PS4's design, new colors, USB 3.0, and difference with XBox One as follows (via http://www.dualshockers.com/2013/09/25/sony-japan-svp-talks-about-the-ps4s-design-new-colors-usb-3-0-difference-with-xbox-one-and-more/) to quote:
Here’s a handy summary of the most relevant points made:
- Affordability was an important goal when developing the PS4, since even if you make a great hardware, it’s hard to sell if it’s expensive. However, performance had to be high as well. It wasn’t easy to strike a balance between these two factors.
- A number of different designs were considered, but the final design was adopted because it felt “new” but it also shown the DNA of PlayStation, especially from the PS2 era.
- Ito-san pushed for the adoption of USB 3.0 technology. While 2.0 was commonplace while the console was being designed, it was argued that 3.0 will become mainstream after the console’s release.
- The USB 3.0 technology is also indispensable for the PlayStation Camera. While the connector has a special shape, its technology is still USB 3.0. The PlayStation Camera’s resolution could not be achieved with USB 2.0 tech due to lack of bandwidth.
- Playing Full games on the PlayStation App will be difficult (today Shuhei Yoshida actually outright denied that possibility) due to the controls that are significantly different from the DualShock 4.
- The evolution of the DualShock 4 controller is the result of a long trial and error process. It’s been fine-tuned due to the feedback from user tests repeated many times.
- The L2 and R2 buttons received some pretty delicate adjustments to their resistance to pressure due to developer feedback. Their angle was also improved. Materials and shape of the controller were reviewed from scratch to increase the comfort and grip.
- The release of different colors of the DualShock 4 (which will available in blue and red as well as black) was due to a strong request from the marketing department.
- Designers were made aware of the possibility of color variations of the console itself from the beginning, and were first asked to design freely and then narrowed the amount of designs down. They were asked: “I want you to to this assuming color variations”.
- Ito’s impression of the Xbox One is that it tries to be an entertainment device, on the other hand PS4 focuses on games. of course PS4 also does entertainment, as Sony is an Audio/Video company after all.
- CD Playback was not included because the idea is to enjoy a variety of content by connecting to the network, so for music you can enjoy it through Music Unlimited. In addition to that when you take photos and videos you can save them to the cloud and enjoy them from there. The PS4 expresses its true value by connecting to the net.
