On a 20 nm process, the A8 CPU block (2x Twister cores) measures 12.2 mm^2.[1] The Exynos 5433 big block (4x A57) measures 15.1 mm^2, while the little block (4x A53) measures 4.6 mm^2.[2]<p>The A8&#x27;s quad-core PowerVR GPU measures 19.1 mm^2. So the extra space used in the Exynos configuration is almost enough to upgrade from a 4-core to a 6-core GPU.<p>[1] <a href="http:&#x2F;&#x2F;www.anandtech.com&#x2F;show&#x2F;8562&#x2F;chipworks-a8" rel="nofollow">http:&#x2F;&#x2F;www.anandtech.com&#x2F;show&#x2F;8562&#x2F;chipworks-a8</a>
