NVIDIA upset it may lose to Apple in mobile GPUs
NVIDIA responded to Apple's claims of performance for the new iPad. Representative Ken Brown told ZDNet that NVIDIA didn't have the benchmark criteria Apple used to claim a fourfold speed advantage over the Tegra 3 processor. As such, it couldn't verify the authenticity of the claims, which it implied might have been biased through the choice of apps.
It was still "certainly flattering" to have been referenced during the event, Brown said, but there were "so many issues" to hash out with Apple's claims.
Some evidence exists to support Apple's point of view. Benchmarks of the ASUS Transformer Prime, the first mainstream Tegra 3 tablet, showed it being outpaced by an iPad 2, a device nearly a year older with a dual-core processor and dual-core graphics. Android 4.0 will have improved its speed in some respects, but the Tegra 3 is still likely to be trailing significantly behind the new iPad's quad-core video and upgraded base processor.
Apple may face more of a competitive threat from the Samsung Exynos 5250, which will use the brand-new ARM Cortex-A15 architecture and new graphics. It won't start shipping by itself until later in the spring, however, and may only reach the market months later.
