Well are the technical specs of each mGPU stated by the laptop OEMs in their product description technical specs list? Places like on the box packaging, in the manual, and on their websites? If not, then perhaps Nvidia needs to get with the OEMs and advise them to detail those specs on their various models so consumers do not think they are getting one or the other chip as everyone has their own needs - some want lower power with less performance but longer battery life, others want more power being plugged into the wall for example.
Perhaps Nvidia can simply just clear up any reference confusion as someone said above and just needs a letter on end of each GPU identifying each. Then Nvidia can reference the info of each mGPU in specs on their website with the hard stamped fabrication performance numbers that are set in BIOS OEMs cannot control with these:
ROPs/TMUs
Shaders
Texture Fillrate
Pixel Fillrate
Bus width
Memory size
Memory bandwidth
^^Those don't change by the laptop OEMs here as the article mentions and Nvidia should put that hard data on their website for each mGPU. Nvidia even lists most of these factory specs for their dedicated GPUs under each model. Just the GPU clock, memory speed, and memory boost speed are set by the OEMs here by the AIB OEM partners so those specs are up to them to report.
This is an easy fix by both parties and doesn't need to cause confusion. I don't think they were doing anything illicit. It just appears to be another oversight disconnect between engineering and marketing (yet again).
