    Better To Wait For The Omap 3630?

    The comparison to OMAP4 made earlier was from OMAP36xx, not 35xx/34xx. In that context, they share the 45nm advantage and some of the increased clock speed, yet OMAP4's upgraded SGX540 core gives it twice the shader pipelines and TMUs for probably around a 2x+ performance increase (not 4x since...

    Power Vs Dreamcast?

    Pretty much any press release, presentation, or fact sheet detailing SGX performance from Imgtec correlates a reference clock of 200 MHz with their claim of ~14M poly/sec for SGX53x. QUOTE PowerVR SGX is available for licensing in three scaled variants (PowerVR SGX510, SGX520, SGX530)...

    Power Vs Dreamcast?

    Imgtec quotes a 200 MHz clock speed to correspond to that 13.5/14M verts per sec figure, and they characterize their figures as being achievable and not the theoretical maximums.

    Carmack, Iphone, Pandora And Midori

    Better image qualities like the higher resolution, lower penalty AA, unconditional 32-bit color blending, and unconditional high accuracy floating point 3D depth could be a reason Carmack finds the iPhone more capable. Perhaps, it's the more advanced graphics features like the DOT3 per-pixel...

    Carmack, Iphone, Pandora And Midori

    The iPhone's API environment reports the VGP in GLBenchmark. http://glbenchmark.com/phonedetails.jsp?be...mp;testgroup=gl Based on comparative performance, I'm assuming the graphics core runs at the speed of the system bus, 103 MHz. Apple had raised the bus's speed in a prior software update...

    Carmack, Iphone, Pandora And Midori

    iPhone apparently equips a VGP Lite to complement its MBX Lite, all running at just above 100 MHz and updateable to higher rates. Pandora would be like a preview of the next generation iPhone/iPod touch with SGX for an interested developer.

    Pandora How Much Performance Can Give The Pandora Gpu

    A low number of shader units isn't bad if their utilization is high, which is the point of Imagintation Technology's heavily multithreaded approach. Imgtec is the same company of which Metagence is also a division, remember.

    Pandora How Much Performance Can Give The Pandora Gpu

    A 660 MHz Cortex would correspond to a 110 MHz SGX530. http://focus.ti.com/lit/wp/spry110/spry110.pdf (page 6) The extrapolation that the clock speeds scale proportionally among the different cores was just an assumption of mine, admittedly.

    Pandora How Much Performance Can Give The Pandora Gpu

    By "around OpenGL ES 1.1", I meant that PSP's feature set was roughly similar to the spec (more similar to 1.1 than a programmable spec like 2.0, at least), not based around it. As assumed, PSP doesn't support DOT3 shading but does have a few of its own advanced features like bezier...

    Pandora How Much Performance Can Give The Pandora Gpu

    PSP is a fixed function graphics platform around OpenGL ES 1.1 in feature set. As to the topic question, Pandora's GPU approximately has GeForce 3 performance with GeForce 7 graphics features.

    Would An Arm Based Psp 2 Be Good For Pandora?

    Next generation phones are the target for Cortex processors. nVidia now addresses that market with CPU-equipped application processors, so they'd need to have some next generation ARM core licensed.

    Omap 3440

    The OMAP3440 is only sampling in a few months, not producing in volume. It's over a year behind the 3430.

    What Is The Clock Frequency Of The Pandora ?

    GPU would then probably correspond at 125 MHz.

    Poll: Battery Life Target

    I suspect the CPU runs at 550 MHz and the GPU at 110 MHz.

    600 Mhz Powerful Enough To

    The SGX530's two shader "pipelines" are probably at the same clock speed as the rest of the graphics core, and that'll probably be at the speed of the system bus.

    Our New Machine, Pandora

    The functionality of even PowerVR MBX, SGX's predecessor, was beyond that of the PSP's most advanced graphics features, like acceleration for beziers and skeletal animation, so emulating functionality certainly wouldn't be the troublesome part of reproducing PSP.

    Our New Machine, Pandora

    Thanks in part to Intel's 45 nm manufacturing process, Menlow does deliver x86, for the first time, in hardware that suits the price, battery, size, and release date constraints of a device like this. Also, it packs an SGX535 GPU, which should yield around 50% higher graphics performance.

    Our New Machine, Pandora

    The dedicated graphics bus of the Axim's 2700G helps its MBX Lite compete surprisingly well with OMAP2420's full MBX + VGP.

    Our New Machine, Pandora

    http://glbenchmark.com/result.jsp OMAP2 devices already outperformed the Axims, so an OMAP3 device like this new system should have multiple times the performance. The most complex demo game from Futuremark's pretty, 3DMarkMobile ES 1.1 OpenGL ES benchmark, Proxycon, was rendered at a...
