Apple’s A5 Beats Nvidia’s Tegra 2 Chip
A recent slew of results have shown that Apple’s A5 chip slaughters the Nvidia Tegra 2 silicon when it comes to graphics. Apple claims that the A5 silicon is twice as fast than the previous generation with nine times better graphics. According to Tiernan Ray from Barron’s, Apple’s chip is two and half times larger than Nvidia’s. He goes on to say that the A5 measures 122 square millimeters versus 49 square millimeters for the Tegra 2 chip.
Now, the Tegra 2 chip is manufactured on a 40 nanometer process while the A5 is on a Samsung 45 nanometer process, making Apple’s chip physically larger. Although both chips run on ARM-designed Cortex-A9 processing cores, the Tegra 2 uses Nvidia’s GeForce tetechnologies rather than Apple’s Imagination tech. Nvidia has plans to narrow the performance gap with the quad-core Tegra 3, named Kal-El, which is expected in Q4 of this year, holding five times the performance of the current Tegra 2 silicon.
Since Apple can afford to use a larger chip, they enjoy better performance. Currently, Apple’s A5 chip only powers the iPad2, but with plans to power both the future iPod Touch and iPhone 5. Both chips have been engineered at their respective companies but have been manufactured by outside sources. Both companies will be giving future business to Taiwan Semiconductor Manufacturing Company for their future 28-nanometer proces. Checkout Nvidia’s roadmap chart below!
