Summary of "DO NOT BUY: AMD Ryzen 9 9950X3D2 CPU Review & Benchmarks | 24 Charts in 24 Hours"
Product reviewed
AMD Ryzen 9 9950X3D2 (aka 9950X3D II / X3D2) — a $900 16-core, 32-thread Zen 5 CPU for AM5 with stacked 3D V-Cache on both CCDs (total 192MB L3), plus a separate IO die. Claimed specs: 200W TDP, 4.3GHz base, up to 5.6GHz max boost.
Main features highlighted
- Dual-CCD V-Cache everywhere: both CCDs use stacked 3D cache, totaling 192MB L3 (vs the earlier 9950X3D having 128MB and only one cache stack).
- Simplified scheduling/core parking: the video argues this makes CPU scheduling easier (less complexity around “which CCD is faster/cached”).
- Real-world framing: testing is presented “as consumers” using public parts/software, rather than AMD vendor-tuned guidance.
- Power draw (Blender all-core worst case):
- about 294W peak
- about 285W nominal at the EPS 12V rails
- software readings around ~250W
What the review found (performance)
Gaming performance (core message: gains are tiny vs price)
- Roughly 0% to 6% faster vs Ryzen 9 9950X3D I.
- Often within error bars / not visibly noticeable (“you could actually observe with your eyes”).
- Examples mentioned:
- Baldur’s Gate 3: 178 FPS, about +5% vs 9950X3D; price up about ~33%.
- Outer Worlds 2: essentially tied (no meaningful benefit).
- Kingdom Come: Deliverance II: about +2.6% vs 9950X3D at 1080p; still small differences at 1440p.
- Dragon’s Dogma II: about +4.8% vs 9950X3D, but still framed as not worth it for gaming.
- Cyberpunk 2077 (medium): within ~1%, functionally the same as 9950X3D.
- F1 25: tied (363 vs 364 average).
- Multiple charts are described as the CPU being “top-ish” but not moving the needle.
Productivity / “experimental” workstation benchmarks
- Mostly 0% to 6% uplift over 9950X3D I in the video’s production/general tests.
- Main exception: OpenFOAM (experimental)
- about +34% vs 9950X3D I
- presented as cache-sensitive, but explicitly labeled experimental and potentially less reliable.
- Other SPEC Workstation items (experimental charts referenced):
- LAMMPS: 2.09 (vs ~270K plus 2.04; vs 9950X3D I 1.97) → about ~6% vs X3D I
- Convolution: 3.07 vs 2.92 (X3D I) → about ~5% better; Intel 270K plus at 2.44
- NAMD: 2.4 vs 2.28 (X3D I), but Intel 270K plus scored 2.87 and is framed as better on value
- Production benchmarks (non-SPEC-style):
- Blender rendering: effectively the same (5.8 min vs 5.9 min)
- Chromium code compile: improvement shown
- 9950X3D2: 88.1 min
- 9950X3D I: 95 min → about ~7.2% faster
- 7-Zip compression: about +9% with the extra cache
- ~215,000 MIPS vs a lower number on X3D I
- 7-Zip decompression: no meaningful benefit
- reruns sometimes tie/near-tie
- cache advantage doesn’t consistently help
Overall takeaway from charts
- Most workloads: 2–5% improvement (often less), sometimes literally within variance.
- Gaming: improvements are described as not worth noticing at the $900 price.
- Central flaw: value—the uplift doesn’t justify the cost.
Pricing / value comparisons (strongly emphasized)
- $900 launch price: described as “astronomical” / high-end.
- vs AMD 9950X3D I: about $657 listed (video notes roughly ~37% more expensive).
- vs AMD 9800X3D: around $464; framed as better value for gaming.
- vs AMD 7800X3D: around $389; described as a very strong value path.
- Competition: Intel Core Ultra 270K Plus
- around $300 at launch, ~$350 at retailers in the video
- in several non-gaming tests, it’s described as punching close to AMD’s $500–$520 9950X tier and offering strong productivity pricing.
- Threadripper: mentioned as faster for some workstation cases, but “priced out” of direct value comparison.
Pros mentioned
- Top performance in select production tasks, e.g. 7-Zip compression (near top of chart) and Chromium compile gains.
- Excellent gaming leadership at the top end (often near-tied for highest FPS), but still not worth it.
- OpenFOAM outlier: potentially very meaningful cache sensitivity (~+34%) if it generalizes to your workload.
- Boost behavior matches claims (mostly): max boost commonly ~5580–5625 MHz vs stated 5.6GHz.
Cons mentioned
- Primary con: not worth $900
- “Almost 0% gain, sometimes 5%” is framed as insufficient.
- Extra cost doesn’t translate into noticeable gaming improvements.
- Gaming value is poor: better options exist at about half the price or less.
- Production value is poor: the regular 9950X (non-3D) is framed as delivering most of what you’d want at $500–$520.
- OpenFOAM caveat: big improvement is on an experimental workload → uncertain real-world applicability.
- Architecture intent doesn’t pay off broadly: the cache/scheduling design doesn’t yield a wide enough uplift.
User experience / practical guidance
- For gaming: don’t buy it expecting a “best gaming CPU.” Performance is described as frequently close or tied, and not worth the extra spend.
- For production: only certain workflows show meaningful uplift; otherwise it behaves similarly to cheaper alternatives.
- Recommendation: a direct “Do not buy” for general consumers based on the charted results and value gap.
Unique points about test methodology / presentation
- Reviewer mentions the CPU arrived quickly and was used overnight to produce rapid multi-chart output.
- Notes an aesthetic issue: the sample shipped appeared upside down (due to source orientation), claimed to be non-performance-affecting—it “just looks different.”
Concise verdict
Overall recommendation: Do NOT buy the AMD Ryzen 9 9950X3D2 at $900.
The video repeatedly concludes that improvements are typically 0–6% vs the cheaper 9950X3D I and often within variance, especially for gaming, while much better value options exist—especially 9800X3D / 7800X3D for gaming and 270K Plus or 9950X for productivity value.
The major exception—OpenFOAM (~+34%)—is on an experimental chart, so it isn’t enough to justify the premium unless that workload matches your needs.
Speakers / contributions (grouped)
- Main reviewer (likely Dave / team-host voice): delivers the “don’t buy” conclusion, pricing/value framing, and most benchmark interpretation.
- Methodology/verification voice (within the same narration style):
- clock validation (boost checks around 5.6GHz)
- confidence framing (experimental vs non-experimental benchmarks)
- measurement context (power, variance, reruns)
- Other referenced contributors:
- Steve (Hardware Unboxed): credited for shipping the CPU
- Arctic: mentioned as sponsor for MX-7 thermal paste, including counterfeit-check context (not a CPU feature)
