Apple fans, start typing your angry comments now, but this review is about rigorous testing and sharp skepticism toward Apple’s M2 Ultra Mac Studio claims. The video opens with the host acknowledging a desire for a positive take, then pivots to a critical examination of marketing versus real-world performance, especially in relation to the M2 Ultra’s potential vs M1 Ultra and competing hardware. The host details the key specifications: M2 Ultra with 24 CPU cores and 76 GPU cores, built on TSMC's enhanced N5P process, and notes that memory bandwidth and the fabric linking the dies remain similar to the previous generation. The discussion then moves into a layered analysis of synthetic benchmarks, real-world rendering workloads, and the impact of software optimization, emphasizing that no single benchmark can capture overall performance. Overall, the video highlights how Apple’s claimed performance leadership evaporates under diverse workloads and questions the value proposition given price, memory limits, and expansion options. The conclusion stresses that power efficiency and thermal behavior matter more in practice, with the reviewer noting that Apple’s marketing should be read against the fine print and real-world benchmarks rather than select graphs. The review finishes by weighing the Mac Studio’s role for professionals who rely on Apple software, contrasting price and performance with a high-end PC build, and acknowledging that for certain workflows the Mac Studio may still offer compelling value despite the criticisms. The first major segment covers impressions and specifications, where the host walks through the external parity with the previous Mac Studio and shifts focus to internal changes. He explains the new M2 Ultra silicon, including a memory bandwidth note and the ultra fusion fabric connections, and then examines the practical implications for display bandwidth, Wi-Fi 6E, and Bluetooth updates. This section also clarifies the different SOC configurations, M2 Max versus M2 Ultra, and the positioning of the new silicon in Apple’s desktop lineup. He then delves into Apple’s claimed performance leadership and examines how the marketing material presents comparisons, warning that the graphs and references sometimes lack clear labeling or transparent baselines. The segment ends with a tepid call to scrutinize the fine print rather than accept marketing at face value, setting the stage for deeper benchmarks. In the second section, GPU-centric benchmarks are dissected, starting with Octane X render performance where the reviewer finds the claimed threefold improvement over M1 Ultra not aligning with observed results. The analysis extends to Redshift and Blender workloads, showing that the M2 Ultra’s gains are highly dependent on the task and that an RTX 4090 still outperforms in many scenarios. The host emphasizes the role of test configuration and memory usage, proposing that pushing the GPU beyond typical RAM capacities could skew results. The narrative reinforces the idea that Apple’s numbers depend on specific, perhaps non-representative, project configurations. A broader takeaway is that a single benchmark cannot define real-world performance, and consumer expectations should account for framework and scene variability. The third section tackles CPU performance and cross-platform comparisons, noting that in single-threaded tasks the M2 Ultra trails an Intel Core i9-13900K by a measurable margin while multi-threaded results can be comparable or superior depending on the workload. Cinebench and Metal-optimized benchmarks are discussed to illustrate how Apple’s hardware can scale differently across software stacks. The host argues that optimization is pivotal, and reliance on select benchmarks can mislead about overall capabilities. The dialogue then moves to color grading and Resolve Studio tests, where the Mac Studio sometimes lags behind a capable PC in a mixed workload, suggesting potential beta software issues or other caveats. The section ends with a call for more transparent testing and independent verification of results. The fourth and final segment assesses power, thermals, and expansion, where the M2 Ultra is reported to draw around 331 watts under heavy Blender metal rendering with room temperature, while idle power sits around 18.5 watts. The reviewer notes throttling rather than aggressive fan speeds under load and warns that hotter environments could cap performance unless fans are aggressively managed. Thermal chamber tests show that lowering ambient temperature does not unlock additional performance, underscoring Apple’s thermal strategy. The expansion topic highlights improved IO capabilities, including HDMI and high-bandwidth networking, and argues that the upgrade path remains compelling for certain professional workflows. Finally, the video weighs value, noting the Mac Studio’s price against a high-spec PC build and acknowledging that for users tied to Apple software, the Mac Studio can still offer a quiet, power-efficient workflow, even if price-to-performance is not universally favorable. The reviewer closes with a practical note on upgradeability and a reminder that value is highly dependent on your software ecosystem and hardware goals.

Questions answered

What is the key hardware spec of the M2 Ultra Mac Studio?
The Mac Studio with M2 Ultra features 24 CPU cores and 76 GPU cores, built on an enhanced 5-nanometer process, with improved memory bandwidth and ultrafusion fabric connecting the dies.
Do benchmarks consistently support Apple's performance claims?
No, the reviewer finds that benchmark results vary by workload and that Apple’s marketing numbers often rely on specific, possibly non-representative configurations, making it hard to generalize.
How does the M2 Ultra compare to an RTX 4090 in rendering workloads?
In many graphics workloads the RTX 4090 outperforms the M2 Ultra, though results depend on the software and task, with some tests showing competitive results in optimized environments.
Is there an issue with Resolve Studio performance on the M2 Ultra?
Yes, the reviewer observed slower performance with Resolve Studio 18.5 Beta in several tests, suggesting potential beta software issues or mismatches with the hardware.
