PSP Wi-Fi Impairs Processor Speed
GameDaily reports that the PlayStation Portable has an interesting restriction: its full processor power cannot be utilized at the same time as its WiFi functionality. Therefore, games that are played online cannot make use of the chip's 333mhz processor speed. The original finding from Beyond 3D was confirmed to GameDaily by Sony. Dave Karraker, Sr. Director, Corporate Communications: "The recent firmware upgrade (3.50) that removed the restriction on the PSP's CPU speed enables developers to utilize speeds either lower or higher than the default 222MHz, up to the full 333MHz clock speed. The article is correct that increased CPU speed cannot be used with the PSP's wireless feature." Though speculation is that this is a power-saving decision, there has been no official announcement as to the root cause.
I mean yeah, some of y'all don't like Sony and point out everything that happens with this company as though it's a "fuckup" (to take an above commenter's description of this limitation). But it's a fact that the wifi being on didn't slow down any PSPs on any game ever published. The spin here may be tough for some to see through, but to fac tis simple, all PSP games were running at a set speed of 222 mhz. These games could have wifi on or off. I presume that somehow there is a power limitation or something other limitation that means you can't run full speed with wifi. I'm sure this isn't design flaw, unless you think every system that could be faster is designed poorly (and virtually every system could be faster). You have to engineer these things. This announcement is that Sony has now INCREASED the processor speed for non wifi applications. It's a bit of GOOD NEWS. I mean, whoop dee do, who cares, but still, this isn't bad news for anyone. It adds a capability that wasn't there in the past. But here's the spin "WIFI IMPAIRS THE PSP PROCESSOR!!!! NICE DESIGN CHOICE HAHAHA!!!" So strange to twist things that radically. I just don't get the whacky spinning. What did Sony do to deserve this special treatment? I'm sincerely curious. Sony has been pretty cool about Linux on its systems so long as it doesn't lead to pirated games. Sony is always pushing things to add features and be innovative... often valuing cool novel features over functionality. That's how we get new cool stuff. Everybody out there uses something Sony invented. Things as basic as optical discs and modern batteries were developed or improved by Sony. I would think Slashdot would have a lot of people who like Sony because it's got cool stuff. Albeit the nice stuff is too expensive. This seems like more than a economic issue. Some of you, and obviously the editor, have a real axe to grind. Reading through these threads, some dude was modded a troll for a single sentence saying "The Cell processor is a really cool piece of technology!" Anyway, I'd like to hear what the real issue is.
or it maybe that when the cpu is running at 333 the system bus is running to fast for the wi-fi chip like how when you overclock the FSB on older MB's the pci bus and other buses speed up as well to a point where it is too fast for the cards / chips on that bus.
You decide whether to play your Playstation Portable at 333Mhz or using WiFi capabilities. You choose to:
1) play at 333 Mhz. Page 108
2) play with WiFi capabilities. Page 42
3) do both! Page 36
p36. "Your PSP reads 'Emergency shut down. Battery dead.' You go to plug in your PSP to recharge it and the bettery explodes. You die.
p42. You experience a decrease in graphics quality but are happy to be playing with people instead of on your own.
p108. You run to your room, lock the door, and admire the 333Mhz in all their glory. You forget where you place the key for the door and die of starvation. One week after your death, your PSP spontaneously turns on, its battery explodes, and your corpse is set on fire.
