Two very different machines land at almost the same price for anyone running AI models at home. Choosing a Mac mini M6 vs a gaming PC for local AI here in South Africa is really a question of memory, software and what else you want the computer to do, because at about R25,600 they offer similar AI capacity.

Quick Answer

The 24GB Mac mini M6 costs R25,599 at Evetech (22 October 2026) and gives about 18GB of AI memory by our index method. The cheapest 16GB gaming PCs, with a Radeon RX 9060 XT, cost R25,999. Both reach the 14B model tier; the Mac has a little more memory, while the PC games far better and can be upgraded later.

🧠 How they hold a model

The Mac mini keeps a single memory pool that the processor and graphics both draw on. On Apple's spec sheet the M6 model starts at 16GB and can be ordered with 24GB or 32GB. Our AI PC Index counts 75% of that for AI, so the 24GB model offers about 18GB.

The gaming PC keeps a separate 16GB of video memory on its RX 9060 XT card, alongside its own system RAM. All 16GB is available to the model. In practice both machines sit in the same tier: around 14B parameters at 4-bit, with room for long conversations.

⚖️ What else separates them

  • Mac mini M6 24GB, R25,599: tiny, quiet and efficient, with a 512GB SSD. Ollama runs on Apple Silicon through the Metal API. Memory cannot be upgraded later, and macOS does not run most Windows games.
  • Ryzen 7 9700X + RX 9060 XT 16GB PC, R25,999: a full gaming PC with DDR5 and a 512GB NVMe SSD. Ollama runs the RX 9060 XT on Windows through Vulkan. You can add RAM or swap the graphics card later.

There is also a cheaper Mac route. The 16GB Mac mini M6 at R17,699 gives about 12GB of AI memory, the same tier as a R17,499 Arc B580 PC.

🧭 Which one to choose

  • AI first, small desk, no gaming: the Mac mini M6 24GB.
  • Gaming plus AI, or you want to upgrade later: the RX 9060 XT 16GB PC.
  • Your tools need NVIDIA's CUDA: neither; budget R32,499 for an RTX 5060 Ti 16GB system instead.
