AMD made waves in the high-end desktop market with their latest Ryzen 5000 series processors, led by the flagship 16-core Ryzen 9 5950X. But at $100 less, the 12-core 5900X has dominated mindshare thanks to its nearly equal gaming prowess yet lower cost.
This has left DIY system builders in a quandary – should they splurge on those extra 5950X processing cores or pocket the savings with a 5900X and spend it elsewhere? Let’s carefully compare the capabilities and real-world performance of these AMD CPUs to help finalize your buying decision.
Today we have an abundance of desktop processors spanning from basic dual-core Pentiums to server-grade 64-core Threadrippers. The Ryzen 9 family competes squarely against Intel’s premium Core i9 parts, catering specifically to enthusiasts wanting extreme multi-tasking abilities like gaming while streaming.
AMD designed the 3rd generation Ryzen 9 5900X and 5950X chips to push boundaries. Built on an optimized 7nm manufacturing process and Zen 3 architecture, these CPUs provide significant IPC (instructions per clock) gains over predecessors along with clock speed bumps. This combination unlocks unprecedented single and multi-threaded prowess ideal for gamers, content creators, and productivity-focused users alike.
But with $200+ price tags these won’t appeal to the mainstream. As you’ll see though, their performance iterates so substantially over what came before that power users can finally leave Intel without compromise. Let’s explore precisely what you’re getting with these red team processors.
Key Architectural Improvements in Zen 3
The Ryzen 5000 series utilizes AMD’s latest Zen 3 core design that refines their existing chiplet approach. But unlike past iterations focused heavily on core count gains, Zen 3 emphasizes single-threaded speed through careful optimization.
Foremost here is a vastly improved 8-core complex (CCX) arrangement allowing lower latency communication between two 4-core units. This CCX now shares an entire 32MB L3 cache segment rather than needing to talk across cores.
Furthermore, AMD reduced pipeline stages from Zen 2 for quicker data delivery and added dual ALUs enabling faster mathematical processing. These changes translate to a 19% overall IPC lift despite similar base clock speeds to earlier Ryzen 3000 chips.
When coupled with AMD’s maturation of their 7nm process node by TSMC, Zen 3 stretches its legs more freely through 50-100MHz higher boost clocks too. Let’s examine precisely how these architectural optimizations manifest for the 5900X and 5950X.
Ryzen 9 5950X vs 5900X – Key Specs and Pricing
While clearly related, AMD endowed the 5950X and 5900X with slightly varying configurations to serve different enthusiast needs. The table below covers how each model’s cores, clock speeds, cache allotments and pricing shake out:
| Specification | Ryzen 9 5950X | Ryzen 9 5900X |
|---|---|---|
| Manufacturing Process | TSMC 7nm FinFET | TSMC 7nm FinFET |
| CPU Cores / Threads | 16 / 32 | 12 / 24 |
| Base Clock Speed | 3.4GHz | 3.7GHz |
| Max Boost Clock (Single Core) | 4.9GHz | 4.8GHz |
| Total Cache (L2 + L3) | 72MB | 70MB |
| Default TDP | 105W | 105W |
| PCIe Interface | PCIe 4 (20 lanes) | PCIe 4 (20 lanes) |
| Current Pricing | $569 | $389 |
With 50% more CPU cores and addressable threads over the 5900X out of the box, the 5950X carries clear advantages for heavily parallelized workloads like 3D modeling/rendering, video editing, game development, and code compiling. Still, outside these scenarios most desktop users see limited benefits from cores 16+.
Gamers in particular derive minimal FPS uplift within modern titles based on current testing. However, more cores delay how long a CPU remains performant as software demands inevitably grow over a processor’s usable lifespan.
Both CPUs offer the same 105 watt power envelope, so cooling solutions carry over easily. Just ensure sufficient thermal dissipation when overclocking to keep these dense 7nm chips humming. I’d recommend nothing less than premium air coolers or 240mm all-in-one liquid units.
Note that AMD prices its 5950X flagship about 30% higher over the 12-core 5900X. However, recent street prices closed this gap where the 5950X only costs $180 extra now – making its value proposition far stronger. Still, cool a full $200+ more than early MSRPs.
Ultimately unless you require stronger multi-threading, I believe most shoppers eyeing these premium parts see the 5900X as the enthusiast sweet spot. Now let’s explore exactly why even outside heavy workstation-focused workflows.
Gaming Frame Rates – 5950X Rarely Justifies Cost
Modern games utilize six or eight processing threads at most. Therefore despite 50% more cores, the 5950X fails to outpace the 5900X by a significant margin when gaming.
Reviewers at reputable outlets like Anandtech, TechSpot, Tom‘s Hardware, and PC Gamer recorded few instances where the 5950X pulled ahead of the 5900X by more than a couple FPS, even at 1080p:
| Game Title | Ryzen 9 5950X Avg FPS | Ryzen 9 5900X Avg FPS | % Difference |
|---|---|---|---|
| Horizon Zero Dawn | 156 | 153 | 2% |
| Borderlands 3 | 126 | 121 | 4% |
| Far Cry 5 | 135 | 131 | 3% |
| Assassin‘s Creed Valhalla | 104 | 101 | 3% |
| Cyberpunk 2077 | 108 | 105 | 3% |
You’d need incredibly high refresh rate monitors pushing 144Hz or faster to feel these differences visually. Otherwise performance appears perfectly matched.
This trend continues at higher 2560×1440 and 4K resolutions using capable graphics cards. Pushing more pixels shifts game loads off the CPU and onto GPUs. Meaning even pricier GeForce RTX 3080 or Radeon RX 6800 XT models hit rendering ceilings before the 5900X or 5950X break much of a sweat.
Ultimately the 5950X averages under a 5% faster frame rate across top titles than the 5900X, hardly justifying its added expense. Money better spent on the latest GPUs, faster memory kits, PCIe 4.0 NVMe storage, or peripherals that better heighten gaming immersion over those four extra CPU cores.
Application Benchmarks Reveal the 5950X’s True Strength
While modern games fail to exploit the 5950X’s full muscle, applications better optimized for heavy multi-threading reveal noticeable benefits from its additional cores.
Productivity software coders, video editors, 3D modelers, researchers, financial analysts and data scientists still value raw processing throughput. AMD architected the 5950X to excel within these scenarios.
Here are some compiled application benchmark results showcasing the 5950X ahead by a wider margin:
| Benchmark | Ryzen 9 5950X Score | Ryzen 9 5900X Score | % Difference |
|---|---|---|---|
| Cinebench R23 Multi-Core | 30470 points | 25124 points | 21% faster |
| Blender Classroom (lower is better) | 6 minutes 20 seconds | 8 minutes 5 seconds | 29% faster |
| V-Ray Benchmark (higher is better) | 19470 points | 15998 points | 22% faster |
| MATLAB Compute (lower is better) | 1.09 seconds | 1.32 seconds | 21% faster |
| PugetBench for Premiere Pro (higher is better) | 1049 points | 886 points | 18% faster |
The 5950X really spreads its wings here by leveraging every ounce of its 16-core design. We see it outpacing the 5900X anywhere from 18-30% depending on workload complexity. For time sensitive video rendering, 3D projects, code compiling and scientific simulations, those extra four cores make tangible impacts.
Note that few applications scale perfectly across this many cores today. So the 5950X’s advantage shrinks in less optimized software. Still, even here it outpaces the 5900X by 15-20% thanks to higher clock speeds aiding lightly-threaded tasks.
Choosing the Right Enthusiast AMD Processor
If your computing priorities center purely on gaming while streaming gameplay, shopping on a second monitor, or juggling Discord chats, I believe the Ryzen 9 5900X sweet spot. Its 12 cores and 24 threads juggle these scenarios effortlessly while pushing triple digit frame rates with gusto.
Use savings over the 5950X on a better graphics card, fast PCIe 4.0 SSD, peripherals, or a sexy case kitted with RGB lighting and tempered glass instead. Unless playing exclusively on 4K or 240Hz monitors, the 5900X keeps up perfectly. It remains my top enthusiast recommendation focused purely on gaming.
Only those running intensive workstation applications focused on media creation, engineering simulations, financial analysis or scientific computing fully leverage the 5950X’s extra 50% core bump. Power users running these apps appreciate the clarity of faster renders and compile times.
Just make sure your supporting components don’t bottleneck performance. I recommend pairing either CPU with speedy DDR4-3600 memory or better, X570 motherboards boasting PCIe 4.0 for rapid storage and GPU bandwidth, and the beefiest GPU within budget. Cool effectively too – 240mm AIO liquid coolers or premium air towers like the Noctua NH-D15.
For everyone else playing the latest Call of Duty, pounding away on office documents, or surfing the web with background Netflix binges, both the 5900X and 5950X prove overkill. Better applying funds toward a well-rounded PC gaming setup built around the Ryzen 5 5600X instead.
