AMD’s Ryzen Threadripper 3990X versus Intel’s Xeon W 28-Core: mammoth among high-end workstation CPUs. Both these giants offer colossal power, but have a few small distinctions in who they target. If you want to buy either CPU for very serious content creation, heavy 3D rendering, or even the most data-intensive tasks, this deep dive will make your choice easier.
Simple Specs: Threadripper 3990X vs. Xeon W
Now let’s look into the specifications that form the basis of the Threadripper 3990X vs. Xeon W argument. 2.9GHz base clock speeds boost up to 4.3GHz with a staggering 256MB of L3 cache, ratcheted to a 280W TDP. 7nm Zen 2 architecture, quad channel DDR4 memory, and 88 PCIe 4.0 lanes are ideal for GPU-centric tasks.
The Intel Xeon W 28-Core in the top-tier versions of the Apple Mac Pro offers exactly that: 28 cores and 56 threads, base clock speed of 2.5 GHz and turbo boosted up to 4.4 GHz. It sports a cache of 66.5 MB, supports 2933 MHz DDR4 ECC memory, and has 64 PCIe 3.0 lanes. So yeah, while the Xeon W does not have PCIe 4.0 support, this is best addressed by the Apple optimization and thermal design.
Performance in Real-World Applications
Both processors are great performers when dealing with demanding workloads, yet performance matters definingly differentially. The Threadripper 3990X, for instance, absolutely and totally annihilates the Xeon W in Cinebench R20, V-Ray. Blender rendering tests due to its high core count specific for multithreaded workloads. It brings down render times significantly even for 3D animation, video encoding, and machine learning workflows.

As opposed to these, the Intel Xeon W performs commendably in certain common macOS optimized workflows, mostly about applications like Final Cut Pro, Logic Pro, and Compressor. A rich integration between Apple hardware and software presents very smooth software stability and synergy. Also, Xeon W performs excellently concerning large data sets and simulations, specifically in scientific computation or even engineering applications.
However, PCIe 4.0 support of Threadripper gives better speed for SSDs and GPUs. Also, since AMD has more memory channels and a much higher bandwidth, users with lots of huge data workflows won’t run into many bottlenecks.
Ideal For: Content Production, Scientific Computing, and 3-D Design
When it comes to video editing, 3-D design, and game development, the Threadripper 3990X is the best CPU for content creators who want top notch thread count and GPU expansion. It’s cheaper per core and made for multitasking, hence ideal for PC-based workstations.
For those who are totally immersed in the Apple environment, built for macOS-exclusive software, the Intel Xeon W 28-core Mac Pro is still a sound option. It has slightly fewer cores but unrivaled stability, longevity, and integration. Creative professionals who work in audio production, color grading, or film editing may benefit from Apple’s hardware optimization.
However, in terms of performance for the dollar, AMD is the clear frontrunner. Not only does the Threadripper nearly double the cores. It allows for more people to work on processes at once, extremely important for virtualization, AI training, and video transcoding.
Backward Compatibility and Ecosystem
The other important parameter under consideration is the price. Threadripper 3990X actually sells for about $3,990, while a Mac Pro with similar specs with the 28-core Xeon W can go upward of $12,000. Suffice it to say: AMD is the clear winner when it comes to value for PC builders and tech enthusiasts. In addition, Threadripper-based motherboards provide ample opportunities for upgrade and customization, be it multiple GPUs or fast NVMe storage.

On the contrary, Apple’s Mac Pro upgrades are no cheap affairs, and for the most part, the components are soldered or locked within Apple’s ecosystem. Another thing with which Apple earns its enterprise and media clientele is most of all support and longevity.
Moreover, the TRX40 platform from AMD is the latest and greatest in terms of connectivity to support ECC memory and has a healthy DIY community. These factors, along with the aforementioned ones, make the 3990X a safe bet for future-proofing.
The Final Verdict: CPU of Your Choice
So, among all the workhorses, the AMD Ryzen Threadripper 3990X wins hands-down for professionals seeking raw multi-core performance, flexibility, and affordability. It crushes the Intel Xeon W 28-core in multi-threaded workloads, PCIe bandwidth, and price performance. The Mac Pro is perhaps one of the smoothest experiences for macOS users, but the price and lack of customization options are major turnoffs.
Thus, for the best workstation CPU for 3D rendering or video editing without the strings of macOS, you should choose the Threadripper 3990X. It packs in more power, offers more expansion options, and a better return on investment for both professional creators and developers.
