The new Intel Atom x5-Z8350, Atom x5-Z8550, and x7-Z8750 will replace the current Cherry Trail lineup soon and they should be a little faster and more reliable.

The updated processors have the same base clock speeds, but support higher CPU burst frequencies of 80 and 160 MHz depending on the model so should go a bit quicker. Intel has fixed some problems with alpha blending and ATSC graphics You see a minor update to the range of SoC Atom replacing "00 " to " 50" .

Here is the product list

• X5 - Z8350 maximum frequency 1.92 GHz , HD Graphics 400 12 EU to 200-500 MHz
• X5 - Z8550 maximum frequency 2.40 GHz , HD Graphics 400 12 EU to 200-600 MHz
• X7 - Z8750 maximum frequency 2.56 GHz , HD Graphics 405 16 EU to 200-600 MHz

All of processors are quad-core chips and Chipzilla is to phase out its current Cherry trail chips to make room for the new models.
Intel is also updating three of its Braswell chips. In January the Celeron N3050, N3150, and Pentium N3700 will be replaced with new models with higher burst speeds and named graphics. There is little in the way of details yet but we will know closer to the date.
