DO NOT BUY: AMD Ryzen 9 9950X3D2 CPU Review & Benchmarks | 24 Charts in 24 Hours

The reviewer discusses AMD's new $900 9950X3D2 CPU, which arrived just 24 hours prior to the video's recording, necessitating a rapid benchmark and analysis. The core message is that, despite some incremental improvements, the 9950X3D2 is largely not worth its high price tag. **Key Performance Insights:** * **Gaming:** In gaming benchmarks, the 9950X3D2 shows minimal gains, ranging from 0% to 6% over its predecessor, the 9950X3D. Against the 9950X (non-3D), improvements are more significant, between 21% and 71%. However, compared to the 9800X3D, the 9950X3D2 often performs similarly or slightly worse. For most gaming scenarios, AMD's cheaper X3D offerings like the 9800X3D or 7800X3D provide comparable or better value, delivering the same or better performance for a fraction of the cost. Many gaming tests showed the new CPU was functionally tied with older models, with improvements being within the margin of error and unobservable to the human eye. * **Scientific/Production Workloads:** In scientific and production tests, including Spec Workstation benchmarks like Lumps, OpenFOAM, Convolution, and NAMD, the 9950X3D2 generally offers only a 0% to 6% improvement over the 9950X3D. An exception was the OpenFOAM computational fluid dynamics test, where the 9950X3D2 showed a significant 34% improvement over the 9950X3D. This test is noted as experimental and highly sensitive to cache, making its real-world applicability uncertain. In production tasks like Blender rendering and Chromium code compilation, the gains are marginal, often within variance or negligible. * **7-Zip:** In 7-Zip file compression, the 9950X3D2 showed a notable 9% improvement over the 9950X non-3D, attributed to its larger cache. However, in decompression, performance was more variable, with no significant advantage seen for the new CPU. **Key CPU Features and Architecture:** * The 9950X3D2 features two CCDs with stacked V-Cache, totaling 192MB of L3 cache. This unified cache approach simplifies scheduling and core parking compared to previous dual-CCD designs with uneven cache distribution. * It is a 16-core, 32-thread CPU based on the Zen 5 architecture, using the AM5 socket. * Its advertised boost clock is 5.6 GHz, with a base clock of 4.3 GHz. * Compared to the 9950X3D, the 9950X3D2 has a slightly lower boost clock (5.6 GHz vs. 5.7 GHz) but more cache (192MB vs. 128MB). Its TDP is also higher at 200 watts versus 170 watts. **Value and Pricing:** * The $900 price point is highlighted as astronomical and the primary reason for the reviewer's recommendation against purchasing the CPU. * The 9950X3D (previous generation) is available for significantly less (around $657), offering most of the same performance benefits. * Gaming-focused X3D CPUs like the 9800X3D ($464) and 7800X3D ($389) are substantially cheaper and deliver comparable or superior gaming performance. * For production workloads, the 9950X (non-3D) at $500-$520 is a more sensible choice, as the X3D variants offer little to no benefit in many production tasks. * Intel's 270K Plus, priced around $350, offers competitive performance in many non-gaming tasks against AMD's $500+ CPUs, making it a strong value proposition in that segment, despite its dead-end socket. **Experimental Benchmarks:** * The reviewer notes that some charts are "experimental," meaning they have less experience with the specific test and thus a higher chance of erroneous data. These include Lumps, OpenFOAM, NAMD, and DaVinci Resolve. While generally confident, they advise users to seek additional sources before making purchasing decisions based solely on these. * The OpenFOAM result is specifically called out as an outlier, demonstrating a large gain but with uncertain real-world implications. **Conclusion:** The 9950X3D2 is presented as an incremental update that fails to justify its premium price. For gaming, cheaper X3D CPUs offer superior value. For production, the non-3D 9950X or Intel's competitive offerings are more sensible choices. The reviewer strongly advises against purchasing the 9950X3D2, emphasizing that the performance gains do not warrant the $900 cost, especially when significantly cheaper alternatives provide nearly identical performance in most scenarios. The exceptional OpenFOAM result is noted as an interesting anomaly but not enough to recommend the CPU.
