AMD Threadripper Pro 7000 Debut: 96-Core Zen 4 CPU Benchmarked
AMD Threadripper Pro 7995WX Benchmarks: CPU, Memory And Web Application Tests
With the help of Dell, we were lucky enough to test the Threadripper Pro 7995WX, AMD’s top of the line, 96-core / 192-thread workstation processor. For virtually all of our previous processor reviews, we’ve configured our own test systems and setup everything up on our own, from flashing BIOSes, to installing operating systems, drivers, and other software.
For this article, we did not have an actual Threadripper Pro 7995WX-powered Dell workstation on hand, but rather remotely accessed a system housed at Dell’s HQ. While we didn’t have physical access to the system, we did install all of our own applications and benchmarks, and did tweak the OS as we normally would. That said, the comparison systems are NOT identical in terms of their memory and graphics configurations.
The Dell Precision 7875 we tested was outfitted with a pair of NVIDIA RTX 6000 Ada Generation GPUs and 512GB of DDR5-4800 RAM, while our previous-gen Threadripper Pro workstation had only 64GB of DDR4-3200 RAM and a GeForce RTX card. The mainstream Intel Core and AMD Ryzen platforms included for reference also used a GeForce, but had 32GB of RAM. We include the mainstream platforms simply for a frame of reference.
For most of these benchmarks, the amount of RAM and GPU configuration won’t have a significant impact on performance, but this is not the same kind of internal review we’d normally publish. Still, we were sure you would be as interested in some benchmarks as we were interested to experiment with such a system, so there was no way we were going to pass up this opportunity.
With that, let’s get on with some benchmarks…
SiSoft SANDRA 2021 Benchmarks
We began our testing with the latest version of SiSoftware's SANDRA 2021, the System ANalyzer, Diagnostic and Reporting Assistant. We ran four of the built-in sub-system tests that partially comprise the suite with the new Threadripper Pro 7995WX-powered Dell Precision 7875 workstation (CPU Arithmetic, Multimedia, Memory Bandwidth, and Cache and Memory Latency). All of the scores reported below were taken with the system running with its default settings, with 512GB of DDR5 RAM running at an effective 4,200MHz, in 8-channel mode.
The Threadripper Pro 7995WX put up some monster numbers in these tests, surpassing 2.5TOP/s in the processor arithmetic test and over 14.4GPixel/s in the multimedia test, while offering over 200GB/s of memory bandwidth.

AIDA64 Memory Bandwidth, Memory Latency & Cache Latency
AIDA64's CPU Cache and Memory benchmarks measure memory bandwidth during read, write and copy operations, in addition to memory latency, and cache bandwidth and latency.
In terms of memory latency, the Threadripper Pro 7995WX-powered Dell Precision 7875 workstation landed at the bottom of the stack, with its DDR5-4800 (CAS 40) RAM. Note, however, that Dell plans to offer faster memory with the system in the future, once higher-speeds DDR5 RDIMMs are more widely available. With faster memory, the latency gap shown here will likely close somewhat.
Geekbench v5.4.1 CPU Benchmark
In the GeekBench tests, we're stressing only the CPU cores in a system (not the graphics card/GPU), with both single and multi-threaded workloads. The tests are comprised of encryption processing, image compression, HTML5 parsing, physics calculations and other general purpose compute processing workloads.
GeekBench's single-threaded test shows the Threadripper Pro 7995WX-powered Dell Precision 7875 workstation outpacing the previous-gen Threadrippers, but trailing the mainstream chips that can boost to higher frequencies and sport lower memory latency. In the multi-threaded test, however, there's no catching the 7995WX. The 96-core Threadripper Pro 7995WX's multi-threaded score is nearly double that of the 64-core, previous-gen Threadripper Pro 5995WX.
Browser & Web App Benchmarks: Jetstream 2 And Speedometer 2
Next up, we have some numbers from the Speedometer 2.0 and Jetstream 2 tests available at browserbench.org. The Speedometer Benchmark test uses a wide array of latency and throughput benchmarks to evaluate web application performance and Jetstream evaluates Javascript and WebAssembly performance; both tests take all of their individual results and tabulate them into a final score.These benchmarks measure performance of an array of browser-based technologies used on modern, rich web applications. Scores in these benchmark are an indicator of the performance users would see when browsing the web and running advanced web apps. All of the systems were tested using the latest version of Microsoft's Edge browser, with default browser settings, on a clean, fully-updated install of Windows 11.
7-Zip Data Decompression Tests
The 7-Zip benchmark measures compression and decompression performance using the LZMA method, which leverages the Lempel–Ziv–Markov chain algorithm to perform lossless data compression. The benchmark produces a final rating in GIPS (giga instructions per second).
7-Zip only offered up to 96 threads with Threadripper Pro 7995WX-powered Dell Precision 7875 workstation configured at NPS2 (two NUMA nodes, effectively half the number of total threads). At NPS1, which is what we tested here, it still only offered up to 128 threads. It should have offered a full 192 threads (and we've seen it run with 192 threads live), but we ran out of time and couldn't dig further.
In any case, the AMD Threadripper Pro 7995WX still crushes every other platform and pulls way out in front in the multi-threaded test, while the single-threaded test gives credence to AMD's claim of little compromise in lightly-threaded workloads.
UL 3DMark CPU Physics Benchmark
For our next series of tests, we moved on to some graphics and game-related metrics with 3DMark, specifically the physics benchmark that's part of the Time Spy test. For the 3DMark Physics test, we simply create a custom 3DMark run consisting solely of the physics test, which is multi-threaded and CPU dependent, and report the results...
Let us be clear -- the AMD Threadripper Pro 7995WX is NOT for gamers, it's not marketed for gamers, and you'd be better served with a mainstream platform if gaming is your primary purpose. That said, we wanted to see how it behaved here. Unfortunately, the tests doesn't come close to utilizing all of the Threadripper's CPU cores or memory bandwidth and ultimately the Threadripper Pro 7995WX lands in the middle of the pack -- ahead of the previous-gen Threadrippers, but behind the mainstream platforms—especially Intel's latest 14th Gen platform, which dominates this test.
