AMD Ryzen 9 9950X Zen 5 CPU: FMAX Frequency Matches Zen 4

Introduction

AMD’s upcoming flagship Zen 5-based processor, the Ryzen 9 9950X, is generating excitement among tech enthusiasts. According to recent reports, the Ryzen 9 9950X boasts a maximum frequency (FMAX) of up to 5.85 GHz, aligning with its predecessor, the Ryzen 9 7950X. Let’s dive into the details.

FMAX and Architecture

The FMAX represents the maximum default clock limit allowed within the BIOS for AMD Ryzen CPUs. In the case of the Ryzen 7000 series (based on the Zen 4 core architecture), the top-tier Ryzen 9 7950X chip operated at 5.85 GHz. Now, with the Zen 5 architecture powering the Ryzen 9 9950X, it appears that the FMAX remains consistent at 5.85 GHz.

Ryzen 9 9950X Specifications

The Ryzen 9 9950X features impressive specs:

• Cores and Threads: 16 cores and 32 threads
• L3 Cache: 64 MB
• Peak Boost Clock: 5.70 GHz (same as the Ryzen 9 7950X)
• TDP: 170 Watts (expected to exceed 200W with Precision Boost Overdrive, or PBO, activated)

Achieving High Frequencies

The 5.85 GHz frequency is remarkable, especially considering the right conditions. Users can optimize performance by ensuring better cooling and sufficient power when utilizing PBO mode. The Ryzen 9 9950X promises both enhanced efficiency and higher performance compared to its predecessor.

FMAX Comparison

Let’s compare FMAX frequencies across different Ryzen chips:

• Ryzen 9 9950X: 5.85 GHz (5.7 GHz Boost)
• Ryzen 9 7950X: 5.85 GHz (5.7 GHz Boost)
• Ryzen 9 7900X: 5.70 GHz (5.6 GHz Boost)
• Ryzen 7 7700X: 5.50 GHz (5.4 GHz Boost)
• Ryzen 5 7600X: 5.45 GHz (5.3 GHz Boost)
• Ryzen 9 5950X: 5.05 GHz (4.9 GHz Boost)

Blender Benchmark and Early Data

An early engineering sample of the Ryzen 9 9950X was tested in the Blender benchmark. With a power target (PPT) set to just 60W (110W less than its default TDP), the chip performed admirably. Notably, it approached the performance of Intel’s Core i9-12900K, even at this lower power level.

Anticipating Zen 5 CPUs

As we approach the expected launch date of July 31, the Zen 5-based Ryzen 9 9950X promises exciting advancements in high-performance desktop computing. Stay tuned for more information on these powerful CPUs!

Remember, the Ryzen 9 9950X’s FMAX of 5.85 GHz is a significant achievement, and enthusiasts eagerly await its official release.
