» thanks qj....
for clearing that up. I actually had no idea the psp could run at 333MHz. glad to see this on the front page because Im sure its still unkown to most people.
QJ get some ****ing news

wow your an idiot, this article isnt about the fact that it can go to 333, its the fact that when using wifi, it wont let you use 333, did you know that dip*****? no you didnt. nor did I, and I find this interesting.

» 2 engines?
why would coders need to develop 2 engines for the 2 clock speeds? I'm sure a lot of games would be just as playable if 5fps slower overall while playing multiplayer.. I'm sure it would lessen the effect of network lag to some small degree.
games have been using that principal for years. the software simply renders as fast as it can. if it can't draw 60 fps, it just renders 30 or 40. someone playing doom on a 486 would probably have just as much chance of winning as someone on a quad core p4 sli setup.

» you know nothing
is not just 5 fps slower believe me, i know
gta lcs is running about 20fps more at 333
if we pull up the cpu at 333 also the bus and the gpu pulls up
at 166mhz
psp gpu while running at 166 with cpu running at 333, it can render about 15 million polygons more
under present conditions gpu can render only 20 million polygons/s
cpu vector unit at 333mhz can give 2.8 gigaflops
at 222mhz vector unit gives only 1.4 gigaflops which has a big impact on physics and pixel fill rate.
so its not just 111 mhz more
for example, if you overclock a pentium 4 3.2 ghz 111 mhz more,the differences in performance are negligible
but as for psp cpu 111mhz its 1/3 (111+111+111=333)
so under present conditions psp is showing only 65% of its full performance.Maybe you can't believe this, but its true

- As for operational frequency it was not 333MHz and was 222MHz
The PSP tip/chip was operational to tell the truth with only the clock of 2/3 of the specifications. Current PSP still being able to show full performance means not to be. In addition, the OS kernel of PSP among the main memories of 32MB, had possessed the 8MB thing area. This is large to exceptional case as a OS kernel area of the game machine.
The motherboard of PSP
In the middle of March was held "GDC (Game Developers Conference)" with, the side which is not excessively known so far generally concerning PSP, made clear. SCEA (Sony Computer Entertainment America), the session which is entitled "PSP Advanced Software Overview" was done with GDC. Among those, Mark DeLoura of SCEA (Manager of Developer Relations), update and software layer of the PSP hardware specifications and the entire image of the tool were explained.
In former official announcement, as for operational frequency of the CPU core of PSP with コンフィギƒ…ラブル, it was the expectation which operates at most 333MHz. But, with GDC, as for the CPU core of PSP, as for present condition when it is restricted in 222MHz, it was explained. It means to be held down to the clock of 2/3 of the specifications exactly. In addition, also bus speed, 166MHz at the time of specifications announcement of the year before last (reverse operation) from is backing up to maximum 111MHz from zone.
"As for CPU is the range to 333MHz, but under present conditions it is locked to 222MHz. Because the bus is typically the half of CPU (the clock), it has become 111MHz. When CPU is pulled up to 333MHz, when deciding, also the bus is pulled up probably will be to 166MHz, "that DeLoura explains.
The down grade to 222MHz has suggested that in provisional specification, there is a possibility of pulling up in the future to 333MHz. In the future, moving to 65nm process and the production process after the that, perhaps at the stage where electric power consumption goes down, to 333MHz it makes improvement possible.
SCEA did not explain the reason where it is restricted to 222MHz finely. But, as recognized even from the fact that this specification modification is explained with the corner of economical electric power, as for low frequency conversion for electrical retrenchment as for being it is clear. PSP, under the present conditions of 222MHz, to use comfortably with the lithium ion battery of 1,800mAh as an operation and a game machine of 4 - 6 hours, is the last line. Because of that, above this increasing CPU frequency, increasing electric power consumption, it is presumed that it was not possible to shave battery drive time. It seems that as for actual solution with semiconductor technology of present condition, is not 333MHz and is 222MHz.
Summary of CPU core. Frequency has become 222MHz with default The graphic engine under present conditions operates with 111MHz
- The electric power consumption decrease of PSP whose hardship is many
Those where it is distinct from the frequency lock of PSP, are that also SCEI and have suffered hardship in electric power consumption decrease. Especially, in case of PSP becoming problem TDP (Thermal Design Power: It is average electric power consumption not only thermal design electric power consumption). As for average electric power consumption, because leak (a leak) electric current echoes largely, with the process which the present time refines it is very difficult to lower. With improvement such as process technology and circuit design, how much can reduce leak electric power, it is one of the future technical hurdles of PSP.
Though, when you look at the whole PSP, the fact that electric power is eaten on the other hand seems like the device other than main chip set. In the explanation with GDC, seeking and the wireless LAN of UMD drive (Wi-Fi), high brightness setting and the like of liquid crystal display, when it is the operation which consumes electric power very it was explained.

thats why i like custom firmware. when i run 333mhz with socom 2 online it does wonders. It also makes slower games like GTA run very well.
