TI: Dual-Core OMAP5 Faster Than Quad-Core Cortex A9

In a video released prior to the opening of the Mobile World Congress, TI compares its OMAP5 chip to a quad-core ARM Cortex-A9 and shows that two cores can outrun four cores, at least in loading web pages.

The OMAP5 processor completed the test run in 95 seconds, while the "commercial" and "competing" quad-core required 201 seconds. While Qualcomm did not mention the name of the competing processor we assume that it was Nvidia's Tegra 4-Plus-1, which is the only quad-core Cortex-A9 chip currently available. Of course, the demonstration was in TI's favor, as the A15 is promised by ARM to deliver roughly twice the per-watt and per-clock performance as the A9, which suggests that it will outperform A9 chips especially in single- and dual-thread applications such as web browsing. The demonstrated OMAP5 chip was running at only 800 MHz, while the quad-core was clocked at 1.3 GHz. According to the manufacturer commercial OMAP5 processor may reach clock speeds of up to 2.5 GHz.

However, it appears that TI has found additional ways to optimize the multithreading performance as an MP3 file was played and a video was downloaded during the web page loading test. We will have to wait for actual phones to be available to determine the real-world performance of the OMAP5, but 2012 shapes up to be an interesting year for smartphone processors - a new entry from Intel with just one core, plenty of dual-cores as well as a few quad-cores from Nvidia, Samsung and Qualcomm.

  • Now put OMAP 5 in the new TI calculators. I'm tired of 12MHZ 68000 chips in $200 calculators

  • I just don't see why we need quad cores in phones. Maybe when they use less battery, but now dual cores are just fine and fast(as this proves).

    Who does super intensive multitasking important stuff on their phone that needs a quad core anyways?

  • Hope this does not surprise anyone although this will be short term as new revs of quads come out. The only thing that is surprising here is that the performance was more than double for the dual core. Could that be partially due to a non-optimized application.

    TI has a long history of really solid engineering.

    Exactly....I agree completely. I would be surprised if 25% of the applications used more than 1 core on a mobile device and if they did use more than that we would probably have much less battery life.
