AMD Threadripper Pro 7000 Debut: 96-Core Zen 4 CPU Benchmarked
LAME XP Audio Encoding Performance
For this test, we created 16 copies of our own 223MB WAV file (an 11 minute Grateful Dead jam) and converted it to the MP3 format using the multi-thread capable LAME XP tool. Processing times are recorded below, listed in minutes:seconds. Shorter times equate to better performance.
This test tops out at only 16 threads (one thread per audio track), which results in a second place finish for the Threadripper Pro 7995WX. Interestingly, it does end up slightly ahead of the Ryzen 9 7950X, though.
As a related aside, we also tested the Threadripper Pro 7995WX with 32 and 64 tracks. With 32 tracks, it still completed the test in around 40 seconds, and with 64 tracks it finished in 1 minute 21 seconds (Lame XP consistently and fully utilizes a maximum of only 32 threads).

Blackmagic RAW Video Encoding Speed
The Blackmagic RAW Speed Test is a CPU and GPU benchmarking tool that tests full-resolution Blackmagic RAW video decode performance. The tool can be used to evaluate the performance at various resolutions and bitrates on the CPU or using OpenCL on a GPU. We're reporting two results here, both using 8K resolution, but at differing bitrates and compression levels.
The multi-threaded Blackmagic RAW speed test has the Threadripper Pro 7995WX finishing on top, besting the previous-gen flagship Threadripper Pro 5995WX by a wide margin.
x265 Video Encoding Benchmark
The multi-threaded HWBOT x265 Benchmark is based on the open source x265 encoder that leverages modern CPU instructions to speed up video encoding. We tested the CPUs represented here with the 64-bit encoder using the default 1080p and 4K workloads.
The x265 video encoding benchmark requires enabling a system's High Precision Event Timer (HPET). Unfortunately, the HPET cannot be enabled on our in-house Threadripper Pro test system (despite Windows reporting that it has been enabled) and our current Intel test bed performs unreliably with HPET enabled. As such, we have only two numbers, but again, the Threadripper Pro 7995WX comes out on top.

Cinebench R23 3D Rendering Benchmark
Cinebench R23 is a rendering performance test based on Cinema 4D from Maxon. Cinema 4D is a 3D rendering and animation tool suite used by animation houses and producers like Sony Animation and many others. It's very demanding of system processor resources and can utilize any number of threads, which make is an excellent gauge of computational throughput. This is a multi-threaded, multi-processor aware benchmark that renders and animates 3D scenes and tracks the length of the entire process. The rate at which each test system was able to render the entire scene is represented in the graphs below.
Chalk up another victory for the Threadripper Pro 7995WX in Cinebench's multi-threaded test. Its single-threaded score lands right in between the mainstream Ryzen processor and previous-gen Threadripper, but that multi-threaded score is in a league of its own.
Cinebench 2024 3D Rendering Benchmark
The recently-released Cinebench 2024 benchmark tests GPU and CPU performance using Maxon’s Redshift render engine. The tool supports AMD and Intel x86/64 CPUs, Apple M1 and M2 SoCs, as well as Qualcomm's Snapdragon compute platform. Cinebench is based on the latest Cinema 4D 2024 and Redshift code using updated compilers (Clang) and has a minimum runtime activated by default. We focused solely on the single and multi-threaded CPU tests here.
The new Cinebench 2024 benchmark also has the Threadripper Pro 7995WX significantly outrunning the previous-gen Threadrippers by a wide margin, in both the single and multi-threaded tests.

POV-Ray CPU Ray Tracing Benchmark
POV-Ray, or the Persistence of Vision Ray-Tracer, is an open source tool for creating realistically lit images. We tested with POV-Ray's standard 'one-CPU' and 'all-CPU' benchmarking tools on all of our test machines and recorded the scores reported for each. Note, we used a beta fork of POV-Ray that scales beyond 128-threads. Results are measured in pixels-per-second throughput; higher scores equate to better performance.
Once again we see the 96-core Threadripper Pro 7995WX significantly outpacing all of the other platforms, dwarfing even the 64-core Threadripper Pro 5995WX.
Blender Rendering Benchmarks
Blender is a free and open source 3D creation suite that can handle everything from modeling, rigging, and animation to simulation, rendering, compositing and motion tracking. It has a purpose-built benchmarking tool that will track the time it takes to complete rendering a particular model (or models). We used the CPU-focused benchmark with all three models currently available...
Blender also shows the Threadripper Pro 7995WX crushing every other platform, nearly doubling the performance of the previous-gen Threadripper Pro 5995WX and offering around 4X the performance of mainstream platforms. This benchmark is somewhat sensitive to memory bandwidth, so faster memory than the 4800 MT/s RAM in our test system may yet improve this score even further.
Y-Cruncher Multi-Threaded Pi Calculator
Y-Cruncher is a multi-core-capable tool that calculates the value of pi to a specified number of digits. In this case, we ran the tool on all threads and had the application calculate the value of pi to 1 billion digits. The values below are the time required to perform the calculation expressed in seconds. As a result, lower values indicate better performance.
Calculating Pi out to a billion digits takes the Threadripper Pro 7995WX less than 10 seconds, and once again, we see AMD's new processor finishing at the top of the heap.

STARS Euler3d Multi-Threaded CFD Benchmark
STARS Euler3d is a computational fluid dynamics benchmark which uses a CFD grid that contains 1.23 million tetrahedral elements and 223,000 nodes. The benchmark executable advances a mach 0.50 Advisory Group for Aerospace Research (AGARD) flow solution for an aeroelastic test wing. The benchmark score is reported as a CFD cycle frequency in Hertz.
This benchmark is multi-threaded, but is also dependent on platform bandwidth, and cache and memory latency, so the final results are not determined by compute performance alone. Cache sizes / speed and memory bandwidth affect the score as well...
It's probably time to retire this benchmark. It wouldn't properly utilize the Threadripper rigs, and performed unexpectedly low on the Zen 4-based processors. Still, we had the data, so we're presenting it here. We don't put much stock in the result though.
