The gain lands on prompt processing, not on how fast tokens stream back. At $2,499 and $5,499 these are the line's highest starting prices. - Author: Marcus Schuler - Tags: AI News, Tools & Workflows Apple introduced a [new Mac Studio](https://www.apple.com/newsroom/2026/08/apple-introduces-new-mac-studio-with-m5-max-and-m5-ultra/?ref=implicator.ai) with M5 Max and M5 Ultra on August 25, 2026, saying the M5 Ultra processed prompts up to four times faster than the M3 Ultra in its July 2026 tests. Neural Accelerators in every GPU core speed matrix multiplication during prompt processing. For people running frontier-class open-weight models locally, that addresses the long pause before an answer begins more directly than the answer’s later speed. What Changed - Apple's new Mac Studio adds Neural Accelerators to every GPU core, aimed at prompt processing rather than at the speed tokens stream afterward. - Apple's own July 2026 tests claim the M5 Ultra processes prompts up to four times faster than the M3 Ultra, and up to 4.3 times its peak AI compute. - The M5 Ultra scales to 512GB of unified memory at 1.2TB/s, which Apple describes as 50 percent higher bandwidth than the M3 Ultra. - The M5 Max starts at $2,499 and the M5 Ultra at $5,499, the line's highest starting prices, and the 512GB configuration slips to late October.

[More on our AI guidelines](https://www.implicator.ai/about/). ## Two phases of one request After a long prompt, prefill builds a cache in the silence before the first token. That work is compute-bound as context grows. Decode starts with the first token, and the stream is limited mainly by how quickly model weights move through memory. The prior Mac Studio exposed the imbalance. [EXO Labs](https://blog.exolabs.net/nvidia-dgx-spark/?ref=implicator.ai) measured an M3 Ultra at about 26 TFLOPs of FP16 compute, with 512GB at 819GB/s. An NVIDIA DGX Spark offered about 100 TFLOPs, with 128GB at 273GB/s. The DGX Spark processed the prompt 3.8 times faster, while the M3 Ultra generated tokens 3.4 times faster. In a [March 25, 2025 test](https://www.hardware-corner.net/studio-m3-ultra-running-deepseek-v3/?ref=implicator.ai), an M3 Ultra took 227 seconds to process a 15,777-token prompt for a four-bit DeepSeek V3 build. Its generation rate fell to 5.79 tokens per second from 21.05 with a 69-token prompt as peak memory use reached 466GB. ## Apple adds matrix compute The M5 Ultra announced August 25 has up to 36 CPU cores, 80 GPU cores, 512GB and 1.2TB/s of bandwidth, which Apple describes as 50 percent higher than its March 2025 M3 Ultra predecessor. M5 Max has 18 CPU cores, up to 40 GPU cores, 128GB and 614GB/s. Apple’s July 2026 tests put M5 Max prompt processing in LM Studio at up to 3.9 times the M4 Max result and M5 Ultra at up to four times the M3 Ultra result. Apple’s broader claim was up to 4.3 times M3 Ultra’s peak AI compute performance. These are prompt-processing or compute figures, not a comparable leap in generated tokens. No independent benchmark of an M5 Max or M5 Ultra Mac Studio existed at launch, because the machines do not reach customers until September 22\. Every M5 Mac Studio multiplier available on August 25 came from Apple’s own tests. FREE WEEKDAY MORNING BRIEFING Don’t miss the next AI story that matters.

It processed 881 tokens per second and generated 65.9 at 4K context, then processed 1,068 and generated 54.9 at 32K. Know someone who'd find this useful?

An RTX Pro 6000 Blackwell with 96GB processed the same prompts 3.46 times faster at 4K, 2.29 times at 16K and 2.41 times at 32K. It generated 50 to 65 percent more tokens per second across those March 2026 tests. ## Capacity and price In July 2026, a rented 512GB M3 Ultra held a 351.7GiB four-bit DeepSeek R1 build entirely in memory and generated 20.3 tokens per second. A GLM-5.2 run that month peaked at 421.4GB. Apple says four Mac Studios linked over Thunderbolt 5 with RDMA ran inference up to three times faster than one system in its July 2026 tests. Pre-orders opened August 25; deliveries and store sales begin September 22\. The M5 Max starts at $2,499, unchanged from the M4 Max’s most recent price but $500 above its March 2025 launch. M5 Ultra starts at $5,499, $200 above the M3 Ultra’s most recent price and $1,500 above its March 2025 launch. Both are the line’s highest starting prices. Rising component costs amid chip and memory demand drove the prices. Apple gave no reason, but the same demand probably delayed the 512GB M5 Ultra, unavailable to order August 25 and due in late October. [AI KIZAI](https://ai-kizai.com/benchmarks/512gb?ref=implicator.ai) wrote in its July 2026 benchmark notes: “Prompt processing (PP) and generation are separate measurements. On Apple Silicon they behave very differently and quoting only one of them is how benchmarks lie.” Frequently Asked Questions What is the new Mac Studio actually good at? Holding a very large open-weight model entirely in memory and working through a long prompt without a long stall. Prefill, the phase that sets the wait before the first token, is compute-bound, and that is where the new Neural Accelerators in each GPU core apply. Token generation afterward is limited by memory bandwidth, which rose by what Apple describes as 50 percent. Does Apple's four-times claim mean answers arrive four times faster? No. Apple's July 2026 figures put M5 Max prompt processing in LM Studio at up to 3.9 times the M4 Max result and M5 Ultra at up to four times the M3 Ultra result. Those are prompt-processing and compute figures, not a comparable increase in generated tokens. Are there independent benchmarks of the M5 Mac Studio? Not at launch. The machines do not reach customers until September 22, so every M5 Mac Studio multiplier available on August 25 came from Apple's own tests. An independent March 11, 2026 test of M5 Max silicon in a 14-inch MacBook Pro measured 881 tokens per second of prompt processing and 65.9 of generation at 4K context on a four-bit Qwen3.5-122B-A10B. How does it compare with an NVIDIA workstation card? In that same March 2026 test an RTX Pro 6000 Blackwell with 96GB processed the same prompts 3.46 times faster at 4K, 2.29 times at 16K and 2.41 times at 32K, and generated 50 to 65 percent more tokens per second. The Mac's advantage is memory capacity rather than compute. What does the new Mac Studio cost and when does it ship? Pre-orders opened August 25, 2026, with deliveries and store sales from September 22\. The M5 Max starts at $2,499, unchanged from the M4 Max's most recent price but $500 above its March 2025 launch. The M5 Ultra starts at $5,499\. The 512GB M5 Ultra could not be ordered on August 25 and is due in late October. AI-generated summary, reviewed by an editor.
