EVGA Tegra Note 7 Review: Nvidia's Tegra 4 For $200
By , Dorian Black

Test System Specs

Today we're comparing the Tegra Note 7 to an odd assortment of devices. As the only other Tegra 4-based Android device, we include the Shield. Because the Note is an entry-level seven-inch tablet, we also have the current Nexus 7 from Google, which retails for just $30 more. The new Nexus also introduces Qualcomm's Snapdragon S4 into the discussion. We're adding last year's Nexus 7 in order to present a very clean comparison between Tegra 4 and Tegra 3.

Moving up the size ladder, the 10.1" Samsung Galaxy Note 2014 Edition is here to represent the company's Exynos Octa 5 SoC along with a Mali GPU. Moving down in size we have two smartphones: Apple's iPhone 5s with the A7 SoC and the flagship PowerVR graphics core, and the Sony Xperia Z1 with Qualcomm's latest Snapdragon/Adreno combo.
