AMD Ryzen Threadripper Pro 9945WX Avis | 78 Données comparées

The AMD Ryzen Threadripper PRO 9945WX is a high-performance, Zen 5-based workstation processor with 12 cores and 24 threads, boasting a 4.7 GHz base clock and up to 5.4 GHz boost. According to PassMark data, this chip achieves a score of approximately 56,125, offering exceptional single-thread performance with a rating of 4,566, making it ideal for CAD and specialized workstation applications. Key advantages include support for 2 TB of DDR5-6400 ECC memory via eight channels and 128 usable PCIe Gen 5 lanes, while the unlocked multiplier allows for frequency tuning. Performance considerations include a 350W TDP requiring robust cooling, alongside a high platform cost due to the mandatory sTR5 socket motherboard. While powerful, the 9945WX is significantly slower in multi-threaded tasks compared to higher-core count models in the 9000 WX-series. Additionally, the processor requires a dedicated graphics card.

The Puget Systems review of the AMD Ryzen Threadripper PRO 9000WX (Zen 5) highlights a 15-25% performance increase over the previous generation in content creation, driven by higher IPC and 6400 Mbps memory speeds. The 96-core processors offer superior rendering performance for tasks like V-Ray and Blender, leveraging 128 PCIe 5.0 lanes and 8-channel DDR5 memory, while maintaining compatibility with existing sTR5/WRX90 platforms. While offering unmatched professional scalability, the high cost and 350W TDP make these CPUs poor value for lightly threaded applications compared to consumer-grade Ryzen 9 chips, which can offer similar performance for tasks like Photoshop.

The PassMark comparison reveals that while the 12-core/24-thread AMD Ryzen 9 PRO 9945 and Ryzen Threadripper PRO 9945WX share similar core counts, they target different markets with the Threadripper offering ~15% higher multi-threaded performance (approx. 56,125 vs 48,634). The Threadripper PRO 9945WX boasts superior workstation-grade, 8-channel memory support up to 2TB and 128 PCIe 5.0 lanes, but carries a significant 350W TDP, demanding heavy cooling. Conversely, the desktop-class Ryzen 9 PRO 9945 provides a highly efficient, 65W, locked processor suitable for business workstations with integrated Radeon graphics. While competitive in single-threaded performance with a 4,619 rating, it is limited to 2-channel memory and fewer PCIe lanes. Ultimately, the Threadripper represents a high-power workstation solution, while the Ryzen 9 PRO focuses on energy-efficient professional computing. For the full comparison, visit PassMark. Copy

The AEC Magazine review highlights the AMD Ryzen Threadripper 9000 Series, utilizing "Zen 5" architecture to deliver a 16% IPC uplift and setting a new standard for high-end workstations. Split into HEDT (24–64 cores) and Pro WX-Series (up to 96 cores), the lineup features faster DDR5-6400 memory and 128 PCIe 5.0 lanes, resulting in significant performance gains in rendering and simulation. Key pros include unmatched multi-core performance, with the 96-core Pro 9995WX dominating Intel Xeon equivalents, bolstered by AVX-512 support for AI workloads. However, cons include extreme costs for Pro models and diminishing returns compared to cheaper HEDT variants, along with high 350W TDPs requiring robust cooling. Furthermore, mainstream desktop chips can outperform the series in single-threaded applications. Copy
