Here's some good advice. Wait for Intel's upcoming Silvermont chip.
In a demo Wednesday at Computex, Intel seemed to instantly -- and thoroughly -- obsolete the existing Atom, known as "Clover Trail," in a head-to-head "bake off," as the Intel demo guy put it.
The "current best-in-class Intel Atom-based tablet" (Clover Trail) was pitted against a tablet with the upcoming (and completely redesigned) quad-core Silvermont Atom (aka, "Bay Trail") packing a new "video encoder and decoder."
The benchmark, TouchXPRT, tests "performance of everyday [tasks] such as photo editing and videos," according to Intel. The demo took two videos and transcoded (converted) them from MPEG-4 to H.264.
Despite starting the Clover Trail Atom tablet first, the Silvermont system quickly caught up and then finished "well before" (quoting the demo guy) Clover Trail.
Check it out at the 34:00 minute mark.
On Tuesday, Intel said Silvermont will offer 2X the CPU (central processing unit) and 3X the GPU (graphics processing unit) performance of the current Atom technology in the market.
