The base 16GB RAM is welcome. It makes it an affordable machine to do iOS development. Though I would likely pay extra to get 32Gb for that (for about the same price that would get me 24GB in the previous model)
Got a tip for us?

This isn't true, actually.
1. Check the specs of the Razer Blade 18. It has a Thunderbolt 5 port that does NOT support DP 2.1; only 1.4
2. The Mac mini's TB5 ports do NOT support USB4 V2.0; only USB4.
3. Charging speeds in TB5 go up to 240W but not every TB5 port needs to support that. The 240W is optional.
So, you see, there ARE optional aspects to TB5.
Yes, you are correct with regards to charging. Only 140 Watt is required and 240 Watt is optional. I didn't really think of that in the context of desktop machines 😅
The Bandwidth Boost Mode of Thunderbolt 5 is based on the asymmetry mode in the USB4 v2 spec though. Thunderbolt 5 ports do support USB4 v2 (40Gbps and 80Gbps) and DisplayPort 2.1 or PCIe Gen 4.
I have no idea what is up with that Razer Blade.

What's better for RAM, M3 Pro with 36GB at the 150GB/s or M4 Pro with 24GB at the 275GB/s speed?
I discussed this issue with another guy, avrtek, over at videocardz(dot)com. He's a veteran who knows what he's talking about. He explained details of what's going on and said that Intel seems to have unofficially/silently loosened its requirements on things like DP 2.1 & USB4 v2, which is why Razer can get away with not supporting DP 2.1 & why Apple can get away with not supporting USB4 v2 (yes, I can confirm that it is indeed not supported by the M4 Pro/Max chips). Oddly enough, the opposite is true - Apple does support DP 2.1 whereas Razer does support USB4 v2.0, both of which are explicitly stated in the respective tech specs.
Head over to the article entitled, "Apple launches Mac Mini with M4 chip: up to 14 CPU and 20 GPU cores, Thunderbolt 5 support." Look for my comment & the thread below it. I hope it helps.
