Why are you considering a mobile Tualatin? They don't quite reach the max speed of their desktop counterparts (1.33 vs 1.4 GHz) and have a lower TDP (22 vs 32.2 W) - though I'm not sure whether thermal throttling would be an issue with a decidedly non-mobile-sized Xbox heatsink on there, and them being able to run at lower voltages should help too, but still - if you try that kind of risky upgrade, might as well go all the way, no? Is it because of prices/availability, are there technical reasons I'm not seeing, or is it a because I can (or want to learn) thing?
I'm glad you asked...
(1) - Since one of my competitors already does a desktop interposer board, I wanted to try and bring something different to the table.
Like you said there's no real problem in just using a desktop CPU but why would you do a CPU upgrade at all other than bragging rights?
You could almost say the same thing about RAM upgrades for the console. Is there any real benefit I don't know but if people want to
pay me to install it I'm not going to say no. I just try and give the people what they want, they seem to be interested in this idea...

(2) - Fitment and cooling of the desktop board can be difficult. People are using the existing heatsink along with a 3D printed mounting bracket.
However, this raises the heatsink up to the point where it makes contact with the HDD caddy. Requiring either modifying the heatsink or caddy.
Using a Taulatin Mobile CPU could keep the heatsink low enough to avoid any additional modification. I recently did a 3D printed design which
allows the installation of 2x 80mm fans over the CPU and PSU for additional cooling. My testers are reporting excellent results...
You can follow my recent works over at OGXbox.com: "https://www.ogxbox.com/forums/index.php?/topi … v3xx-sneakpeak/"

(3) - In regards to power, a desktop CPU on it's own might be fine but what worries me if you consider all mods that can be installed to a OGXbox console,
modchips, HDMI mods, ARGB leds, dual 80mm fans, etc... I begin to worry about the capability of the aging PSU's, there only like 130-150 watt.
More power efficient CPU could be of a benefit here...

(4) - With modified bioses it is possible to overclock the CPU. I've had reports of someone overclocking desktop 1.4Ghz CPU to 1.5Ghz.
With that I'm sure the mobile 1.33Ghz CPU could be overclocked to 1.4Ghz or more...
(5) - Well this will definitely be a learning experience for me as I've never done anything with CPU's like this before, not even sure where to begin really...
