Meet the Tegra APX and CSX
By Charlie Demerjian: Sunday, 25 May 2008

NVIDIA IS GOING to release two types of CPUs in the near future. On June 3rd, according to the slides from this week's reviewers day. Luckily as they forgot to invite us, they forgot to NDA us as well so we can tell you all about the Tegra APX 2500 and CSX 600/650 while others can only fume. Awwwww. ARM11 based system on a chip. This one is aimed at handheld devices in the same way that Atom is. The chip itself comes in a 144mm2 package, not die, and can do 720p encode and decode at 14MBps. It supports the same last gen features as much of the current GeForce line, can do AA and AF, and will support OpenGL ES 2.0. The big brother CSX 600 and 650 is aimed at larger machines with screens between handhelds and real laptops. It runs Wince, not XP or Me II because it is not x86, and in general makes you question why they bothered. The chip itself has 256K of L2 cache and can be die stacked to keep the footprint small.
