Who is excited for NGP?

Oh wow, it is a quad GPU? Twice more GPUs than the 5970 lol. But not as powerful

GPU cores... I'm not sure how many shader processors (and texture units etc) are on each core, but PowerVR has designed them to be easily added together. The 5970 has two GPU. Not to minimize the PowerVR SGX543MP4+, its probably has improved per core performance over the SGX540 (I read 50%) and it has 4 of them.

doesn't the DS sell way more games? i also see and hear about way more DS releases. quite honestly, i never hear a thing about the PSP, and only heard about the NGP about a few weeks ago.

i have a PS3...i don't really need a portable version of it. do i? i'm not really sold.

For your case I would definitely say the 3ds is the way to go. The psp when it came out offered near ps2 games-- which was the problem. It didn't really do anything unique other than play games on the go.

With the NGP you are getting essentially the same thing, but this time it is watered down ps3 games. If you have a ps3, I would definitely go for the 3ds. The NGP will be great for someone who doesn't own or want to own a console, but wants near console experience on a portable.

Each core has a dual stage pipeline, so roughly it's around 8 shaders. The thing about the PowerVR series that's awesome is that they are tile based renderers. Meaning... only what's visible in a scene is what's rendered, unlike Tegra where everything is rendered whether you can see it or not. Tile based renderers are much more efficient with much less resources.

*shakes head* Hmmm...








Nope, I don't know what are those

So how do they do offscreen rendering techniques such as double buffering? Additionally, traditional GPU are capable of a technique called culling, where they will not render that which is out of the viewspace... I better read up on PowerVR.

Binning. PowerVR's driver stack takes and bins N+1... so it's always one frame in cache while one is being rendered, and so on and so forth. They've been working on that same premise for quite some time.

i'm definitely getting the 3DS, but i'll be keepin my eye on the NGP as well. from a hardware standpoint, the thing is a beauty. i just want to see some real world performance before i spend my money on one cuz i don't want it to be just another PSP. i wanna see what all that beefy hardware can actually produce. u know what i mean?

So you mean the next frame is binning while the current is being rendered? That makes a lot of sense. From what I understand, the "traditional" method is to flush the back buffer, then continue to draw to it, repeat? This site has a lot of information (it might be a bit out-dated).
