The M4 Max wins on memory capacity (128 GB vs 32 GB), not raw throughput. For workloads that fit on both, the 5090 is faster. For workloads that only fit on the M4 Max, the M4 Max wins by default.<\/p>\n<h3>Can the M4 Max run Llama 3 405B?<\/h3>\n<p>The 128 GB M4 Max can run Llama 3 405B at IQ2_XXS or Q2_K (very aggressive quantization, noticeable quality drop) at ~2 tokens\/sec. It&#8217;s technically possible but impractically slow for daily use. For Llama 3 405B at decent quality, you need the M4 Ultra 512 GB Mac Studio or a multi-GPU server build.<\/p>\n<h3>Why doesn&#8217;t Apple just make an M4 Ultra Max with more bandwidth?<\/h3>\n<p>The M4 Ultra exists (512 GB unified, ~819 GB\/s bandwidth) and is the right answer for users who need both massive memory and faster bandwidth. It&#8217;s only sold in the Mac Studio form factor, starts at ~$5,000, and goes up to ~$12,000 fully maxed. For 200B+ models locally, it&#8217;s the right buy.<\/p>\n<h3>Does MLX support all the same model architectures as PyTorch CUDA?<\/h3>\n<p>In 2026, MLX supports every major model family: Llama, Mistral, Qwen, Phi, DeepSeek, Gemma, Mixtral, command, Stable Diffusion, FLUX, and most vision encoders. Where it falls behind PyTorch is on <strong>brand-new research architectures<\/strong> \u2014 a paper released last week may not have MLX support for 2\u20134 weeks, where CUDA usually works on day 1.<\/p>\n<h3>Can I fine-tune on Apple Silicon in 2026?<\/h3>\n<p>Yes, well. MLX-LM and Hugging Face&#8217;s MLX integration support LoRA and full fine-tuning. For smaller models (\u226413 B), the M4 Max is genuinely competitive with mid-range GPUs. For larger fine-tuning, the M4 Max can do it (the memory is there) but takes 2\u20134\u00d7 longer than a 5090 + 64 GB system would.<\/p>\n<h3>Is a Mac Studio M4 Max a better buy than a 5090 desktop in 2026?<\/h3>\n<p>For LLM-heavy workloads needing big models: yes. For image\/video generation and CUDA-first research: no. They&#8217;re optimized for different use cases. The Mac Studio is $619 cheaper than an equivalent 5090 desktop build with similar storage, runs cooler\/quieter, and addresses 4\u00d7 more memory \u2014 but loses meaningfully on per-token speed and CUDA-only software.<\/p>\n<h3>What about the M5 \/ M5 Max coming in 2026?<\/h3>\n<p>The M5 Max (expected H2 2026 in the next MacBook Pro refresh) is rumored to improve bandwidth to ~700 GB\/s and add a more capable NPU. Don&#8217;t wait if you need the hardware now \u2014 the M4 Max is a known quantity, available immediately, and the improvements expected in M5 are evolutionary not revolutionary.<\/p>\n<h2>Bottom line<\/h2>\n<p>The RTX 5090 and Apple M4 Max 128 GB are not competing for the same buyer. They&#8217;re optimized for opposite ends of the AI hardware spectrum:<\/p>\n<ul>\n<li><strong>5090<\/strong>: maximum throughput on workloads that fit in 32 GB.<\/li>\n<li><strong>M4 \u0645\u0627\u0643\u0633<\/strong>: maximum addressable model size with acceptable throughput.<\/li>\n<\/ul>\n<p>If you can articulate which side of that line your AI work sits on, the decision is obvious. If you can&#8217;t, you probably want the 5090 \u2014 it&#8217;s the more versatile starter and the lower-cost entry, with no awkward surprises for the 80% of workloads that fit comfortably in its memory.<\/p>\n<p>The M4 Max becomes the right choice when &#8220;running giant models locally&#8221; stops being a hobby and becomes a daily workflow \u2014 at which point its unified memory architecture is genuinely the only consumer-priced way to do it.<\/p>\n<p>Either is a fine 2026 purchase. Neither will feel slow or obsolete in 2027. The risk of buying wrong is real but recoverable \u2014 both have strong resale markets, and the typical 2-year ownership window keeps depreciation manageable on either side.<\/p>","protected":false},"excerpt":{"rendered":"<p>The RTX 5090 is faster per token.
