Core spec detail

Hi all

Do you have NXP official data of following spec ?

I want to compare the spec by devices.

1. Cortex-A8 Core (i.MX515：800MHz)
　***mW/MHz
***DMIPS/MHz
***DMIPS/mW

2. Cortex-A7 Core (i.MX7Solo：800MHz)

***mW/MHz

***DMIPS/MHz
***DMIPS/mW

3. Cortex-A7 Core (i.MX6ULL：792MHz)
　***mW/MHz
***DMIPS/MHz
***DMIPS/mW

We have following efficiency data (DMIPS/MHz):

A7 core (i.MX6: UL and ULL, i.MX7x) -- 1.9 DMIPS/MHz
A8 core (i.MX 5x) -- 2.01 DMIPS/MHz
A9 core (i.MX6 except UL and ULL) -- 2.5 DMIPS/MHz

Have a great day,
Victor

Hi Viktor Linnik

Thank you for sharing the data.

Do you have other data which means DMIPS/MHz and DMIPS/mW ?

We have no more information locally.

However we can ask Design Team if they have such details. Please create a technical case:

Hi b36401‌

I made case #001129.

Could you follow and ask to the Design Team ?
