AMD Ryzen 9 9950X vs Intel Core Ultra 7 270HX Plus Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear split between these two processors. The AMD Ryzen 9 9950X dominates in raw multi-threaded throughput and data-heavy workloads, while the Intel Core Ultra 7 270HX Plus counters with commanding single-core and efficiency-oriented wins.

The largest margin in the entire comparison belongs to the AMD part in PassMark integer math. The Ryzen 9 9950X scores 242097 against 122449 for the Intel chip, a 97.7% advantage. That is nearly double the integer throughput, a decisive result for compilation, spreadsheet calculations, and general productivity tasks. Extended instructions tell a similar story: the AMD processor posts 71564 versus 39283, a 82.2% lead. Data compression follows with 896544 against 493179, a 81.8% gap in favor of the Ryzen 9 9950X.

The AMD processor also wins in multithreaded workloads that stress all cores. PassMark multithread shows 66030 for the Ryzen 9 9950X versus 48270 for the Intel part, a 36.8% margin. Random string sorting goes to AMD by 57.2%, with scores of 94368 and 60020. Data encryption favors AMD at 44366 against 37813, a 17.3% difference. Cinebench R15 multicore is another AMD win: 6335 versus 4224, a 50% advantage.

The Intel Core Ultra 7 270HX Plus strikes back in single-core tests. The most extreme gap is Cinebench R23 single-core, where Intel scores 5917 against AMD's 2202, a 62.8% lead. Cinebench R15 single-core shows 596 versus 344, a 42.3% advantage for Intel. PassMark single-thread is nearly identical, with Intel at 4764 and AMD at 4737, a slim 0.6% edge. The Intel chip also wins PassMark physics, 3843 versus 3279, a 14.7% margin. Prime number finding goes to Intel, 482 against 345, a 28.4% lead. Floating point math is close, with Intel at 163567 versus AMD's 159063, a 2.8% difference.

Cinebench R23 multicore is the one anomaly where the pattern flips. Despite AMD's dominance in other multithreaded tests, Intel wins this one: 41913 versus 40924, a 2.4% margin. That is a narrow result, but it shows the Intel chip can hold its own in certain heavily threaded rendering workloads. Across the full head-to-head set, AMD wins 7 tests and Intel wins 8, a remarkably even split.

Where Each One Wins

The workload split is stark. AMD's wins concentrate in integer math, compression, encryption, extended instructions, and general multithreaded throughput. These are tasks that benefit from the Ryzen 9 9950X's 16 cores and 32 threads, and the data shows margins ranging from 17.3% to 97.7%. For anyone running parallel compute, database operations, or data processing pipelines, the AMD part is clearly the stronger choice.

Intel's wins are equally consistent but in different areas. Single-core performance is the standout, with Cinebench R23 single-core showing a 62.8% lead. Physics simulation and prime number finding also favor Intel, suggesting workloads that depend on per-core efficiency rather than thread count. The floating point math result is close enough to call a tie in practical terms, but Intel takes it on the recorded numbers.

The Cinebench R23 multicore result deserves attention. Intel wins by 2.4%, which contradicts the broader multithreaded pattern. This suggests the Intel chip's architecture handles certain render workloads more efficiently, despite having only 20 threads versus AMD's 32. The Intel part also uses less power on paper, with a 55 W TDP against AMD's 170 W, but the benchmark data does not directly measure power consumption.

The Verdict

The data points to two distinct usage profiles. The AMD Ryzen 9 9950X is the choice for integer-heavy parallel workloads. Its 97.7% lead in integer math and 82.2% lead in extended instructions are the largest margins in the entire comparison. Data compression, encryption, and multithreaded PassMark scores all favor AMD by substantial margins. The 16-core, 32-thread configuration delivers measurable advantages in tasks that scale with thread count.

The Intel Core Ultra 7 270HX Plus is the choice for single-threaded performance and physics-based workloads. Its 62.8% lead in Cinebench R23 single-core is the defining statistic. The Intel part also wins in prime number finding and physics, and it edges out AMD in Cinebench R23 multicore despite the thread disadvantage. The PassMark single-thread result is effectively a tie, so the Intel advantage narrows considerably in that particular test.

The overall average benchmark score favors AMD: 74640 versus 61834. The AMD part sits at the 94th percentile of all CPUs, while the Intel chip sits at the 93rd. Nearest rivals for AMD include the Ryzen 7 PRO 9745 (0.2% lower average score) and the Ryzen AI 9 HX PRO 475 (0.2% lower). Intel's nearest rivals include the Core i9-13900KF (0% difference) and the Core i9-13900K (0.1% higher). These context numbers confirm both processors sit in the same performance tier overall, but with very different strengths.
