Apple appears to have prematurely revealed the name of its rumored lower-cost MacBook model, which is expected to be announced this Wednesday. A regulatory document for a “MacBook Neo” (Model A3404) has appeared on Apple’s website. Unfortunately, there are no further details or images available yet. While the PDF file does not contain the “MacBook Neo” name, it briefly appeared in a link on Apple’s regulatory website for EU compliance purposes.
Not who replied to you originally but,
You aren’t wrong (you even stated that more is probably better) , just not necessarily presenting the whole picture.
Ram compression isn’t a benefit only scenario, there is a cost in processing power to make that happen.
So it’s a trade off of memory utilisation vs processing requirements.
Whether or not it’s worth it is down to circumstance, though i agree that generally i think it’s worth the tradeoff.
Unified memory is useful in specific circumstances, most notably LLM/ML scenarios where high vram utilisation is part of the process.
It’s not an apples to apples comparison by any means.
