@masterz87: It's *really* not.

H2O (Mk.5):

Code:

ntx_hwconfig -v -s /dev/mmcblk0 CPU
[27] CPU='mx50'

Code:

cat /proc/cpuinfo
Processor       : ARMv7 Processor rev 5 (v7l)
BogoMIPS        : 166.57
Features        : swp half thumb fastmult vfp edsp neon vfpv3 
CPU implementer : 0x41
CPU architecture: 7
CPU variant     : 0x2
CPU part        : 0xc08
CPU revision    : 5

Hardware        : Freescale MX50 Reference Design Platform
Revision        : 50011
Serial          : 0000000000000000

Forma (Mk.7):

Code:

ntx_hwconfig -v -s /dev/mmcblk0 CPU
[27] CPU='mx6sll'

Code:

cat /proc/cpuinfo
processor       : 0

CPU revision    : 1

Hardware        : Freescale i.MX6 SoloLite (Device Tree)
Revision        : 0000
Serial          : 0000000000000000

Relevant to our interests, the former is a Cortex A8 paired with one or the earliest iteration of the EPDC to support Carta screens, while the latter is a Cortex A9 paired with the very latest EPDC.
Even if you forget the CPU (which you may, as the main drawing point of the A9 is better power efficiency, and we've established that, at least given Kobo's current SW platform and constraints, parallelism wouldn't help much, so an i.MX7D like on the Oasis 2 wouldn't bring much), there has been *massive* improvements between these two revisions of the EPDC.

It really helped in closing the gap between Amazon and Kobo in terms of how well the screen is exploited (Amazon is still miles ahead, because $$$, but, still).

Each new Kobo 'Mark' introduced a new SoC. Mk.6 was basically just Kobo playing catch up by following Amazon in moving towards i.MX6 boards (A9, slightly more recent EPDC).
