Real PSP performance numbers

[version]

gpu's bezier performance:

4 x 4 : 928k/s
16 x 16 : 58k/s
64 x 64 : 4k/s

yes edram bandwith less than ps2, but resolution and polygons size smaller, framerate 30 on psp not 60
more polygons on psp , lesser pixels

framerate 30 on psp not 60

Frame-rate can be 60 fps on PSP: Ridge Racers renders at 60 fps IIRC.

xbox can't 60 fps, then psp handy stronger than that? , aham
sharp lcd in psp don't refresh the screen with 60 fps

What on earth are you talking about?? :|

Any console since the PS1 can render at 60fps, depending on the game. And the PSP LCD screen refreshes at at least 60Hz. My guess is the "standard" 75Hz for LCD screens, but i could be wrong.
There is nothing stopping any platform released in the last 10 years to render at 60fps, apart from heavy data loads. The Xbox can render at 60fps.
Now, can you stop with the PSP is more powerful than PS2 and Xbox cause it renders at 60fps and has bezier curves crap?
PSP is what it is, it is in no way more powerful than those 2 consoles. Beziers or not.

Well to be exact - the refresh rate is 60hz, but the pixel response time isn't fast enough to keep up with it - which results in ghosting in 60fps games.
But they still run at 60.

Yes. Quake III won't deliver theoretical rates. And then put in Warcraft III, Far Cry, Everquest II... That is the point.

Hell, we don't even have the "straight numbers asked for" from the PS2 despite years of development and an active performance measuring tool. We have a few tantalizing numbers thrown out from time to time, but the rest is always kept under wraps, and we have no active way to compare between game types, from year to year, etc. And yet some demos and code bits can spit out ponderously-enormohuge-figures-of-no-use-whatsoever.

The querent wants more than we've already gotten from other MUCH more known targets, and... it's likely we'll NEVER know well enough.

what I am saying is Sony, Nintendo (I think they tried to state real world numbers for NGC), MS, and just about every other hardware company out there state numbers and in reality they are stating absolute maximum performance of the hardware in theory.

Now if you really could render 275Million 8 textured pixels per second on a 9500 Pro or 9700Pro card that would be enough to draw at least

1600*1200 at a blistering 1145 fps

Fact neither card can do this so...... I personally thing that any numbers released for a video chip's performance are marketing hype....

... Ever since people started caring about graphics, well before consoles were invented. So?

What does it matter ?

Your statement "Xbox cannot do 60 fps" is still wrong: even if no game had come out in 60 fps mode on Xbox YET, your claim would still be wrong.

Well there is Burnout...
I admit, that's not really a car game though

Also Rallysport Challenge 1 and 2 on Xbox run at 60FPS. First Project Gotham too. Versus, drop that nonsense

Ridge Racers on PSP clearly runs at 60FPS, btw. and so does Lumines.

Wow! A 2d game @ 60 fps! That has never been seen before!!1

Not the point. The point was that the thing can run applications at 60fps. Like anything this side of the Genesis.

Arguably not anything - Afaik NGage screen has an actual refresh rate limit of 30hz - and while you can still run application faster then that, there's no way to display it.
I believe many phones that run games have pretty low screen refresh rates also.

 

[see colon]

well, technicaly ntsc tv's only display 30fps and pal 25fps. but it doesn't stop the game from running at 60hz internaly.

30FPS 2D games are not uncommon (Metal Slug series comes to mind) but Lumines definitely runs at 60FPS.

60 Hz (NTSC) == 60 half frames per second
50 Hz (PAL) == 50 half frames per second

A game running at 60 fps framerate is effictevly only showing 30 full frames per second on an interlaced NTSC (60Hz) system. A 30 fps game would effictively only be showing 15 full frames per second. In the end though, a 60 fps game does benefit from the doubled framerate, even if only half the frame is shown at each refresh.

YAY!!! The six-monthly "TVs only display 30/25fps!!!!" thread!
