AMD has launched its Threadripper 9000 series, a flagship workstation platform. Released in July, it features new architecture, improved I/O, and enhanced Instructions Per Cycle (IPC). This article explores the Threadripper Pro 9000 WX and 9000 HEDT models.
About Threadripper Pro 9000 WX‑Series
The Threadripper Pro 9000 WX-Series from AMD incorporates Zen 5 architecture. The top-tier 9995WX model offers up to 96 cores and 192 threads. All models in this series maintain a 350W Thermal Design Power (TDP) and can reach boost clocks of up to 5.4 GHz. They support 8-channel DDR5-6400 RDIMM memory, allowing for up to 2TB, and provide up to 128 PCIe 5.0 lanes through AMD’s WRX90 chipset.
AMD claims a 16% IPC improvement compared to the Threadripper Pro 7995WX, a claim supported by independent testing in various applications. Significant performance increases have been observed in real-world scenarios, such as up to 2.4 times faster V-Ray rendering, 2.2 times faster Keyshot, and a 78% boost in Adobe After Effects workflows when compared to rival products. For AI inference tasks, like DeepSeek R1 32B, the new architecture reportedly achieves approximately 49% higher throughput than similar Intel Xeon offerings.
Other available models include the 64-core 9985WX, 32-core 9975WX, 24-core 9965WX, and 16-core 9955WX.
About Threadripper 9000 HEDT
The Threadripper 9000 High-End Desktop (HEDT) series, designed for consumers, features up to 64 Zen 5 cores, such as the 9980X with 64 cores and 128 threads. This line supports quad-channel DDR5-6400 memory, up to 80 PCIe 5.0 lanes, and shares the same 350W TDP and 5.4 GHz boost clock limit as its Pro counterparts. Models in this series include the 64-core 9980X, 32-core 9970X, and 24-core 9960X.
While the HEDT Threadripper shares core design and clock speeds with the Pro series, it omits certain enterprise-grade features. It is restricted to 4-channel memory and 80 PCIe lanes, making it suitable for enthusiasts, content creators, and small-scale developers who do not require the comprehensive feature set of a full workstation.
AMD’s benchmarks indicate that the 9980X can achieve up to 108% better performance than the Intel Xeon W9-3595X in demanding computational tasks. Additionally, it shows performance increases of up to 83% in Cinebench R23 and 80% in Adobe After Effects when compared to previous generation Threadripper or Xeon hardware.
Improvements over the 7000 Series vs 9000
Microarchitecture & Scheduling
- Zen 5’s branch predictor can predict two branches per cycle, an improvement over the single branch prediction in previous Zen architectures. This enhances fetch throughput and performance in branch-intensive operations.
- Pro chips exhibit an approximate 16% increase in IPC over Zen 4, with generational gains of about 26% reported in Pro benchmarking against the 7995WX.
- Enhanced floating-point execution and prefetch logic lead to more consistent scheduling in both multi-threaded and vector workloads.
IO and Memory
- Both Threadripper 9000 series support DDR5-6400 memory, effectively doubling the bandwidth compared to the DDR5-5200 of the previous Threadripper generation. Pro models feature 8-channel memory, supporting up to 2TB, while HEDT models offer quad-channel memory, supporting up to 1TB, though actual capacity depends on module availability.
- PCIe expansion has significantly increased, with Pro models (WRX90) offering up to 128 lanes and HEDT models (TRX50) providing up to 80 lanes. This is a substantial increase from the approximately 48 lanes in the Threadripper 7000 generation, leading to double the data throughput for GPUs and NVMe storage.
- All models now include full AVX-512 support with a 512-bit datapath, which enhances performance in computationally intensive tasks such as scientific simulations, AI applications, and encoding.
Microcode/BIOS
- Updated BIOS and microcode allow Threadripper 9000 and Pro chips to be compatible with the same sTR5 socket. Feature availability is determined by the chipset: WRX90 for complete Pro functionality, and TRX50 for HEDT and Pro with reduced lane and channel support.
- Scheduling optimizations have been implemented to manage the high core density of Pro variants, such as the 96-core model, aiming to reduce latency across chiplets.
