That’s because PC people try to equate specs in dissimilar architecture with an OS that is not written explicitly to utilize that architecture. They haven’t read enough about it or experienced it in practice to have an informed opinion. We can get downvoted together on our “sub standard hardware” that works wonderfully. lol
The only memory-utilization-related advantage gained by sharing memory between the CPU and GPU is zero-copy operations between the CPU and GPU. The occasional texture upload and framebuffer access is nowhere near enough to make 8 GiB the functional equivalent of 16 GiB.
If you want to see something “written explicitly to utilize [a unified memory] architecture,” look no further than the Nintendo Switch. The operating system and applications are designed specifically for the hardware, and even first-party titles are choked by the hardware’s memory capacity and bandwidth.
The Tegra is similar being an SoC, however it does not possess nearly as many dedicated independent processing cores designed around specialized processes.
The M1 has 10-core CPU with 8 performance cores and 2 efficiency cores, a 16-core GPU, a 16-core Neural Engine, and all with 200GB/s memory bandwidth.
The M1-3 is still miles ahead of the Tegra, I don’t disagree. My point was that software designed specifically for a platform can’t make up for the platform’s shortcomings. The SOC itself is excellently designed to meet needs well into the future, but that 8 GiB of total system memory on the base model is unfortunately a shortcoming.
Apple’s use of memory compression stops it from being too noticeable, but it’s going to become a problem as application memory requirements grow (like with the Switch).
Sure, but no one is saying 8GB is good enough for everyone. It’s a base model. Grandma can use it to check her Facebook and do online banking. It’s good for plenty of basic users. I have an M1 Mini with 8GB that I use as a home server. It works great, but I need my M2 MBP with 16GB UM to use FCP, PS, and Logic Pro. With that, I can master 4K HDR in FCP from an unmastered source in Logic Pro without high memory pressure, let alone swap. There’s no way I’d have the same performance from a PC with 16GB of RAM in Adobe Premiere and Pro Tools. I’ve been there before.
8GB really is a suitable low-end configuration, and most Mac users would agree. I’m not surprised a magazine dedicated to PC gaming hardware thinks otherwise.
