Hi,

Does anybody know how many triangles per second,
which seems to be a pretty good metric of 3D graphics
speed, the PSP can draw versus the PS2?

I tried a PSP today briefly and was impressed, however
the screen seems somewhat low-resolution compared to
the PS2. Nevertheless I could see myself buying one,
especially when better games come out.

Thanks for any info.

I will answer your question before your name gets you burned at the stake.
While the PSP doesn't hold up graphically to the extent of the PS2, the fact
that it is on such a small screen tricks the eye into thinking that you are
looking at identical if not sometimes better graphics but it is only because
of the scale of what you are playing.

I've only tried the PSP once, and I will probably wait to buy one
until a real shoot-em-up game comes out, but it was indeed
a novel experience.

Previously I had only used the Gameboy portable, where the
PSP really offers an entire other 3D world right in your
hand. Bizarre yet wonderful.

My only real gripe: Sony is being pissy about Linux, preventing
the development of the kernel port via the new firmware.
Lucky for them the PSP is still unique.

There are probably a number of games on the PSP where the graphics are
better than the graphics of many games on the PS2; it's just that the
PS2 is capable of providing better graphics than the PSP (altho that
doesn't have anything to do with the original question).
Speaking of the original question: what the hell does the technical
output of a system have to do with a system which you have held in your
hands and have found the graphical output to be good?

While I agree with most things that you have said Ted, the only thing I will
say is that I have yet to see a port of a PS2 game that had BETTER graphics
on the PSP. It may look that way because of the screen size but true
graphics whores will point out that it is not the case. I personally don't
really care about that negligible difference because I will sacrifice that
for portability any day.

Socom is coming to the PSP

Is there a non-portable Gameboy? ;)

There are programs that circumvent the firmware restrictions but I have yet
to try any of the things I see at www.psp-hacks.com for fear of turning my
psp into a $200 paperweight.

Hi, I can tell you what I remember from the official Sony specs.

first, Playstation2:
66 million vertices / triangles per second calculated by the Emotion
Engine, and 75 million triangles per second can be drawn by the
Graphics Synthesizer (obviously the EE can only feed 66M per second to
the GS, thus as a result the EE can never overload the GS


ok now the PSP
PSP can *calculate* 33 or 35 million vertices / triangles per second
at the full 333 MHz clock frequency, which currently restricted to 222
MHz, so that cuts vertex / triangle rate down by 1/3. so, this
33~35 million per sec is currently at about 22-23 million per sec. at
222 MHz. Remember, this is the amount that can be transformed /
calculated, so you can think of this PSP triangle/sec number as you
would the 66M per sec that Emotion Engine in PS2 does.

I do not know how many triangles per second the PSP can actually draw
and display on screen. it is most likely significantly less than 22-23
million per sec. I am going to take a guess - my guesstimate, I
would say, is maybe around 5 to 8 million triangles displayed on
screen (peak) with texture mapping, lighting, gouraud shading,
filtering, etc. which is somewhat higher than what Dreamcast could
do, but not much higher.

current games on PSP are probably pushing significantly less than 5-8
million triangles on screen. maybe a million or two million. again,
just a guess. Definitally alot more than the amount of textured and
lit triangles that the PS1 could do in games
(180,000 /sec max) which is less than one fifth of a million, or what
N64 could do (160,000 /sec max) also less than a fifth of a million.

PSP is easily 10 times more powerful than PS1 or N64, maybe 20 times
more powerful, and also noticably more powerful than Dreamcast - but
PSP is significantly *less* poweful than PS2, Gamecube or Xbox.
however because the PSP renders to a smaller screen with less pixels
than a 480p television, combined with the fact that PSP's GPU has a few
hardware features that PS2 does not have, the *equivalent* power the
PSP has is very comparable to the PS2. however, since PSP is
currently restricted to 2/3 of its max clockspeed, we are not seeing
the full capabilities of the machine, even concidering first generation
software.

now to be clear, nobody is saying that PSP has some kind of magical
hidden power locked in it that will be seen later. all I am saying is,
we will see more and more of the potential of PSP later on, once the
clockspeed limitation is removed, combined with the fact that, as
always, game developers get better at using the hardware later in the
lifecycle.
