Exclusive: Sony PSP2 arriving in 2010, features PowerVR SGX543 graphics - Bright Side Of News*

Okay, the strength of a GTX 260 Core 216 is far fetched. They'd have to go with the octal core design of the PowerVR SGX chip clocked at 400mhz. But it is very possible that it could deliver graphics on par or even better than the 360 and ps3. Especially seeing how it has the benefit of working with a small screen at lower resolutions. By using the quad core design at a low clock rate of 200mhz or a dual core design at 400mhz, they could have the power of the 8600 series. That is good considering the ps3 uses a gpu stronger than the 7800gtx and the xbox 360 has a slightly stronger gpu than that. At least it is within this generation of strength though. This also shows that the next generation of consoles might be coming soon. Maybe in 3 years since the psp released 2 years before the ps3 did.

It also looks like the ARM architecture is taking off.

They could be using 22nm. Look at the gt220, even though it is a miserable card, it's power consumption is very low and it has power above the 8600 series.

Oh wait, they can't be using 22nm, that comes out in 2011, they will probably use 28nm.

ps3 has 1000x the power of ps2

Its a fact. Ken Kutaragi told me so.

If the PSP2 does come in a year, it will piss off PSP Go users who just bought the system...

/less than a year after the PSP Go was released?

So what? First next-gen Nintedo DS using nVidia Tegra to deliver XBox quality graphics, now it's PSP2 using quad-core PowerVR SGX to deliver close-to-PS3 graphics quality? Are these people... dreaming by any chance? :p

Quad-core PowerVR SGX >= GeForce 8600? LOL

No, really... these people have such an imagination. Just as a small recap, a single PowerVR SGX is about half the performance of Intel GMA 950. :p (or almost the GMA 950 in the better cases) Now... multiply that by 4 and you can get the right figure in the best case scenario. Looks like someone didn't do their homework...

Actually the performance of the core is actually not being lied about. When you look at it and scale linearly the performance is as expected.


PowerVR SGXMP variants available as single and multi-core IP

* Performance scales linearly with number of cores and clock speed
* Available in single to 16 core variants
o SGX543 (single core) 35M poly/s @200MHz
o SGX543MP4 (four cores) 133M poly/s, fill rates in excess of 4Gpixels/sec @200MHz
o SGX543MP8 (eight cores) 532M poly/s, fill rates in excess of 16Gpixels/sec @400MHz


PowerVR - Wikipedia, the free encyclopedia

With one core, when you divide the strength of the 4 core by three you get 1Gpixel per second, the gma 950 is actually stronger with 1.6, and the 8600 has about 4. Just because the gma is weak doesn't automatically mean that this entire thing will be weak. How strong do you think the 4870 would be if you stripped away 75% of it's power.

lol "Strength"...

No offense really, but all these technical stuffs are just pure marketing bull trying to coerce buyers into purchasing stuffs that they have absolutely no idea what it does. :p

For instance, the fillrate. It means how fast the GPU can rewrite the VRAM area, it does not necessarily mean how fast the GPU is at processing the data thrown at it. So if you're watching a video decoded by the CPU where the GPU only has to output frames, then fillrate is important, but other than that, it's pretty insignificant.

And as much as I'd hate to say it, GFLOPS is more... of an appropriate representative of a GPU computing prowess, and the error margin is usually around 20% when you compare GFLOPS, so it's acceptable to some extent if you make some additions and subtractions. :innocent:

And the GFLOPS figures are as follow:

Current PSP VFPU: ~2.6 (GPU for you...)
PowerVR SGX single-core: ~0.9
PowerVR SGX quad-core: ~3.6 (estimated... provided it's the best possible conditions)
Intel GMA 950 + a nominal Celeron CPU: ~6.4
nVidia Tegra GPU estimate: ~25
PS3 RSX (G70 based): ~200
360 Xenos (R500): ~240
HD 4870: ~1.2
GTX 285: ~1.1 (dual-issue)

Note that Intel GMA 950 figures will change according to the CPU it's coupled with since it offloads quite an amount of work to the CPU.

I'll let you decide the rest. :)

Nope, it'll just have more kickass graphics. :p 30GFLOPS provides almost up to XBox level... and XBox wasn't bad at all when it came to graphics.

Though that GFLOPS figure for nVidia Tegra was for the next generation. The current one probably tops out at around 3 or less since it's a mobile design... and last I heard, nVidia claimed the next generation of Tegra would be 10x faster... so yeah. :p

I'm assuming Nintendo licensed the next generation and not the current one. Otherwise, the next Nintendo DS might be able to match (or slightly surpass) current PSP graphics while providing battery life up to about 4x better than what the PSP is currently getting.

That is to say... PowerVR SGX *might* be a viable solution in case Nintendo goes with the current gen Tegra, or in case Sony would like to improve battery life to some extent... PowerVR SGX quad-core would still be much more power-efficient than the current PSP hardwares.

The ps2 had 6gflops of power in the Emotion Engine and vector units alone so I'm guessing that those numbers are off a little. By following the specifications, the PowerVR would be weaker than the current PS2 so something must be up.. I doubt that something with such a high polygon count(The ps2 itself could push a max of 75million with no textures lighting etc.) could have such a low gflop rating, it is probably since the gflop rating isn't completely accurate but these are really stark differences.

Maybe the full specification of the powervr sgx isn't out yet.

EDIT:
Oh wait, I think that the numbers you are posting are from the powerVR sgx. This new chip is not the SGX, it is the SGX543. It is a new generation that would explain everything.

SGX is PowerVR 5. :innocent: That's why the full name is SGX5xx, otherwise it's still SGX and there's no "newer generation" in there.

GFLOPS should be used as an indication of how fast the a GPU can calculate geometric transformations, among other things. The poly rate is just like fillrate, only representing the peak theoretical output that a processor can set up polygons. In other words, if the transformation processors cannot match the theoretical output then the poly rate would have a large overhead. But you want that because you don't want to limit or drop anything when it comes to final output. So... take for example, the PlayStation 2. While the GS can theoretically set up 75MPolys/sec, the reality is that the vector units V0 and V1 don't normally match up to that kind of performance and most PS2 games end up being around 5MPolys/sec to 10MPolys/sec. Note though, that that is not the peak number of polygons per frame... as the frame rate can be lower than 60/sec, so something like 100KPolys/frame would be more representative. Other factors come into play before a frame is rendered, so that too is something to consider.

You should be able to gauge a single-core PowerVR SGX performance by taking a look at the iPhone. Here's an upcoming iPhone game:

YouTube - Asphalt 5 - iPhone/iPod touch - Game Trailer

So I'd say... it could produce graphics that look better than a PS2 thanks to having to work with a smaller screen buffer (unless Sony wants to bump the resolution of the PSP2 to beyond 480 x 272) but the most I think it can do is match XBox's graphics and not more.

Plus those specs are only theoretical, PowerVR is still developing these chips so there is no telling if their final version will be able to match the numbers on paper. And it's a multi-core design, too, and we all should know very well by now how multi-core designs fare in terms of efficiency... :innocent:

The SGX is apart of generation 5, these new chips are apart of the 5XT generation they can also be called the SGXMP


The cards named 53x and 540 and a few others are apart of the genertion 5, the SGX543 series and on are generation 5XT

Also, about the multi core thing, these are the gpus, not the cpus, with gpus the performance scales almost if not linearly with more cores.

As you can see from the wikipedia page, the core that apple is using is from an earlier generation and an earlier series.
