TI Shows off OMAP5430 GPU Performance before Computexby Brian Klug on June 3, 2012 11:55 PM EST
Before MWC 2012, TI showed off OMAP5 performance in a video which compared CPU performance to Nvidia's Tegra 3 SoC. The occasion this time around is Computex, and TI has delivered once more with a video comparing GPU performance on the OMAP5430 to the iPad 3's A5X. As a reminder, OMAP 5430 is designed for a 28nm process and consists of two ARM Cortex A15s and two Cortex M4s alongside SGX544 MP2 graphics, whereas Apple's A5X is two Cortex A9s alongside SGX543MP4 graphics.
The video shows the OMAP5430 tablet running GLBenchmark 2.5 at 1080p (the newest upcoming version we're eager to get our hands on) alongside what is basically without doubt an iPad 3.
Update: I asked TI for the specific GLBenchmark 2.5 beta version, and was told that the GLBenchmark 2.5 version is C24Z16 and the resolution is 1080p in all tests (on and off screen).
Performance on the OMAP5430 tablet is shown to be 38 FPS on screen (1080p) and 45 FPS offscreen without vsync, compared to 34 FPS and 43 FPS respectively for the "market-leading tablet." There's another slide showing comparisons to OMAP4470 which consists of two Cortex A9s alongside SGX544MP1 graphics.
You might be wondering how an SGX544MP2 can match an SGX543MP4 - the answer is most likely just higher clocks on OMAP5430's 544s compared to A5X's 543s (Update: As reader Jeff points out, TI has already disclosed OMAP5430's SGX544MP2 clocks as up to 532 MHz). It's hard to know for certain, but this is the most logical answer - you can ultimately either increase ALUs or increase clocks to get to a given performance target. Either way, TI's OMAP5430 is shaping up to be quite a performant SoC both in CPU and GPU at this point, and we look forward to seeing and benchmarking a lot more of it before summer is over.
