AMD Ryzen Threadripper PRO 9995WX Overclocked to 5 GHz: 186K Cinebench Score

The release of AMD's latest flagship processor has shattered expectations, delivering unprecedented performance metrics that redefine the boundaries of workstation computing. The AMD Ryzen Threadripper PRO 9995WX, a powerhouse built on the advanced Zen 5 architecture, has successfully been overclocked to run at a uniform 5 GHz across all 96 of its cores. This extraordinary feat yields a Cinebench R23 score exceeding 186,000 points, demonstrating a massive leap in multi-threaded processing capability. However, this performance comes at a significant cost, with power consumption reaching nearly 950 watts and temperatures climbing to 98 degrees Celsius under standard liquid cooling.

The AMD Ryzen Threadripper PRO 9995WX has been overclocked to 5 GHz across all 96 cores, achieving a Cinebench R23 score of 186,800 points while consuming 947 watts of power. This represents a 70% performance uplift over the default settings of its predecessor, the Threadripper PRO 7995WX, highlighting the immense potential of the Zen 5 architecture despite the extreme thermal and power requirements.

What is the AMD Ryzen Threadripper PRO 9995WX?

The AMD Ryzen Threadripper PRO 9995WX stands as the crown jewel of AMD's workstation processor lineup, designed to handle the most demanding professional workloads. Built on the optimized TSMC 4nm process node, this processor integrates 96 cores and 192 threads, offering a staggering amount of parallel processing power. The chip utilizes a complex chiplet design, comprising 13 distinct chiplets, which includes 12 Compute Die modules and one Integrated I/O Die. This architecture allows for a massive cache configuration, providing 384 MB of L3 cache and 96 MB of L2 cache to ensure data is readily available for the cores.

The processor supports eight channels of DDR5 memory, capable of running at speeds up to 6400 MT/s, which is crucial for bandwidth-intensive applications. Furthermore, it offers up to 148 PCIe lanes, with 144 lanes being usable, and 128 of those lanes are based on the high-speed PCIe 5.0 standard, facilitating rapid data transfer for multiple high-end GPUs and storage devices. The default Thermal Design Power is rated at 350 watts, though actual consumption under load can be significantly higher. Priced at $11,699, it targets enterprise users and professionals who require maximum computational throughput.

How Does the 5 GHz Overclock Change Performance Metrics?

Overclocking the Threadripper PRO 9995WX to 5 GHz across all cores significantly alters its performance profile, pushing it beyond its factory specifications. In standard Power Build Optimization mode, the processor consumes up to 840 watts and achieves a Cinebench R23 score of 173,452 points. However, when manually overclocked to 5 GHz, the score jumps to an impressive 186,800 points, representing a substantial increase in rendering and simulation capabilities. This overclocked configuration draws 947 watts of power, which is a notable increase from the default Thermal Design Power.

The system used for this benchmark featured an ASUS Pro WS RTX50-SAGE WIFI motherboard with BIOS version 1106, paired with 144 GB of DDR5-6000 memory running at CL32 timings. The processor reached a peak temperature of 98 degrees Celsius under standard All-In-One cooling, indicating the intense thermal load generated by such high-frequency operation on all cores. This performance represents a 70% uplift over the default performance of the previous generation Threadripper PRO 7995WX, which scored 109,811 points in the same benchmark.

Why Does High Core Count Overclocking Matter for Workstations?

High core count overclocking is particularly significant for workstation environments where multi-threaded performance is paramount. Unlike consumer processors, where single-core speed is often prioritized for gaming, workstations rely on the ability to process thousands of threads simultaneously for tasks such as 3D rendering, video editing, scientific simulations, and software compilation. The Threadripper PRO 9995WX's ability to maintain 5 GHz across 96 cores demonstrates the effectiveness of the Zen 5 architecture in scaling performance with core count.

While the world record for the previous generation 7995WX stands at 210,702 points, achieved using liquid nitrogen cooling and a 6.25 GHz overclock, the 9995WX's air-cooled 5 GHz score of 186,800 points is remarkably close. This suggests that with advanced cooling solutions like liquid nitrogen, the 9995WX could potentially exceed 250,000 points in Cinebench R23, surpassing all existing Threadripper and Xeon processors. Other benchmarks at 4.9 GHz further illustrate this dominance, with scores including 8.526 seconds in Super PI 1M, 4 minutes and 50.912 seconds in Super PI 32M, and 849,221 MIPS in 7-ZIP compression.

What Are the Thermal and Power Challenges of the Zen 5 Architecture?

The extreme performance of the overclocked Threadripper PRO 9995WX comes with significant thermal and power challenges that users must address. Consuming nearly 950 watts of power requires a robust power supply unit and a motherboard capable of delivering stable voltage to the CPU under heavy load. The peak temperature of 98 degrees Celsius on standard All-In-One cooling is dangerously high for sustained operation, as it approaches the thermal throttling limits of the processor. This necessitates the use of advanced cooling solutions, such as custom water loops or liquid nitrogen, to maintain stability during prolonged workloads.

The 13-chiplet design, while efficient for manufacturing, can complicate heat dissipation, as heat must be transferred from multiple dies to the integrated heat spreader. Additionally, the high power consumption increases operational costs and heat output in data centers and workstations, requiring enhanced cooling infrastructure. Despite these challenges, the performance gains justify the investment for professionals who need maximum throughput for their computational tasks. The motherboard and memory configuration also play a critical role in achieving these results, requiring high-quality components to support the extreme electrical demands.

How Does the Threadripper 9000 Lineup Compare to Previous Generations?

The Threadripper 9000 series introduces a comprehensive lineup of processors, each tailored to different performance and budget requirements.
