2 cores (can be) better than 4: TI OMAP 5 benchmark preview (video)
The upcoming TI OMAP 5 processor will be one of the first chips designed around the ARM Cortex-A15 architecture. Theoretically it will offer more power than today’s fastest chips, while using less energy. But that’s theory. How does is stack up in practice?
Pretty well, if a new demo video from Texas Instruments is anything to go by.
The company pitted a dual-core OMAP 5 against a “competing” quad-core processor using an ARM Cortex-A9 design. NVIDIA’s Tegra 3 processor is pretty much the only such chip on the market today, so there’s a good chance that’s what the competing chip was.
The test involved playing MP3 audio, downloading a video file, and loading websites with HTML5-heavy graphics.
Oh yeah, the OMAP 5 chip was clocked at 800 MHz, while the competing chip was running at 1.3 GHz.
TI probably wouldn’t have released the video if their chip lost… but what’s impressive is that the tablet with the OMAP 5 chip complete the test in less than half the time of the tablet with the Cortex-A9 CPU.
We’ll have to wait until early 2013 to get our hands on products with OMAP 5 processors — and by then it might not be the only game in town. But if you’ve been wondering what the real-world performance difference between Cortex-A9 and Cortex-A15 chips looks like, now you know.
