Atom Z2420 and Z2480 are in the works

In January Intel launched "Medfield" smartphone platform with Z2460 "Penwell" system-on-a-chip, that integrated single Atom core. The processor supported such performance enhancement technologies as Hyper-Threading and Burst Performance (BPT), and so far it has been used in a few smartphones, such as XOLO X90 and Lenovo K800. Atom Z2610 was the second "Penwell" chip, planned for the Q2 2012. One of the first products with this SoC was Lenovo Pad K2110. It seems that in the near future the Medfield platform could be expanded with two more processors. Intel today published Product Change Notification, which detailed modifications in transport media for Atom CPUs. Along with the change description, the PCN contained a list of affected Atoms. Beside aforementioned Z2460 and Z2610, the documents revealed two new SKUs, Z2420 and Z2480. In addition to processor numbers, the PCN also included clock speeds of unreleased CPUs, which very well could be their maximum Burst Performance frequencies:

The PCN states that the Z2420 will run at 1.2 GHz. Because the CPU is based on Penwell design, it should have 1 core and 512 KB L2 cache. That's all we know about this SKU.

We have more details on the Atom Z2480, and mainly because it was already featured in Motorola RAZR i smartphone (you will find specifications here). According to multiple reports, that smartphone will have Z2480 single-core microprocessor with Hyper-Threading, and with up to 2 GHz frequency. The "up to" part tells us that the CPU supports Burst feature, and 2 GHz is the maximum BPT frequency. Base frequency and TDP of this model are not known.
