Hardware difference between Mk1 and MK2?

  • Well, Kemper could easily tell us the differences to put this speculation to rest. It's been questioned on this forum and several others.

    It is weird that we haven't been told what component upgrades were made given this is a piece of technology. Computers, tablets, phones, etc. all tell you what they upgraded when they release a new product.

    Anyways, assuming Kemper isn't pulling a fast one - this is an easy fix for them. Just tell us what you changed.

  • From what I've found out from A.I. is that MK1 has a 72Mhz chip and 98KB RAM and the Mk2 has a 204Mhz chip and 264KB RAM. The Mk2 has a lot more power...

    MK1

    The application processor is believed to be

    NXP LPC2478FBD208

    Specifications:

    • ARM7TDMI-S
    • 72 MHz
    • 512 KB Flash
    • 98 KB SRAM
    • USB 2.0
    • Ethernet MAC
    • LCD controller

    This chip is responsible for:

    • UI
    • display
    • knobs
    • MIDI
    • USB
    • filesystem
    • Rig Manager communication

    MK2

    NXP LPC4357FET256

    Specifications:

    • Cortex-M4 @ 204 MHz
    • Cortex-M0 coprocessor
    • 264 KB SRAM
    • external memory interface
    • much faster USB subsystem

    This explains

    • much faster boot
    • quicker UI
    • additional USB audio channels
    • more simultaneous system tasks

    without changing the profiling DSP.

    The MK1 specs you show only relate to the Toaster and Rack MK1. The Stage was the first real upgrade of hardware since the original MK1. So it begs the question is the Stage, like the Player, really a MK2?

  • Ok so there is a video going around of the internal comparison between the Mk1 and MK2 stage. The video maker, which is an official verified Instagrammer, claims there are no hardware differences.


    Whats your thought

    my thoughts are that guy is an idiot that doesn't know shit and should shut his fcking mouth. Anybody that questions , 13 years gone by in tech of new developement and believes all is the same has to be a complete moron . You wanted my thoughts... move on

  • Agreed. The new hardware is facillitating the dawn of a second 15 year era of technological innovation and creativity rather than some idiotic big corp conspiracy that would prove catastrophic to a companies hard won reputation once exposed.

  • Interesting - but, as someone who works in IT I'm always skeptical of AI provided info.

    Again, Kemper could easily just tell us.

    I don't like A.I. myself except for examining data which I do all the time. A.I. is extremely accurate depending on if you query it accurately.

    No. The Mk2 has a different chipset.

    ComponentStage MK1Stage MK2
    Main application processor (CPU)Older ARM7TDMI-S based MCU (~72 MHz)Newer ARM Cortex-M4 + Cortex-M0 dual-core MCU (~200 MHz)

    I'd say that pretty much closes this thread. :)

    I would add to this....I'm not into people trying to speculate on this stuff.

    There is a point where I don;t care, I'm interested in the output and whether that is worth the money, not the how.

    It would be like counting the components and saying they are only worth £xx, therefore Kemper is ripping us off...totally ridiculous. This amateur sleuthing carries no credibility with me... if its that easy, go create it yourself.
