Architecture Differences

The AMD Ryzen 9 9955HX is built on the Zen 5 architecture with the codename "Fire Range" and belongs to the 9000 series. It is manufactured on a 4 nm process at TSMC. The chip includes 16,630 million transistors across a dual-die design with each die measuring 70.6 mm². The Intel Core 9 273PTE uses the Bartlett Lake codename and is fabricated on Intel's 10 nm process. No transistor count or die size is recorded for the Intel part.

Both processors share an L1 cache of 80 KB per core. The AMD has 1 MB of L2 cache per core and 64 MB of shared L3 cache. The Intel has 2 MB of L2 per core and 36 MB of shared L3 cache. This gives the AMD a substantially larger total L3 capacity, which helps in workloads with large working sets.

The AMD uses AMD Socket FL1, while the Intel uses Intel Socket 1700. The AMD has an unlocked multiplier, meaning it can be overclocked; the Intel has a locked multiplier. The AMD's integrated graphics are the Radeon 610M, while the Intel uses UHD Graphics 730. The AMD supports PCIe Gen 5 with 28 CPU lanes; the Intel supports PCIe Gen 5 with 16 CPU lanes. Both support ECC memory. The AMD supports only DDR5, while the Intel supports both DDR4 and DDR5, a notable difference for platform flexibility.

The AMD is a mobile part with a TDP of 55 W, while the Intel is a desktop part with a TDP of 45 W. The AMD has a base clock of 2.50 GHz and a boost clock of 5.40 GHz. The Intel has a base clock of 1.40 GHz and a boost clock of 5.50 GHz. The Intel's higher boost clock contributes to its single-core win in Cinebench R23, but the AMD's higher base clock and larger core count drive its multi-core dominance.

Head-to-Head Benchmarks

The benchmark data shows a decisive overall advantage for the AMD Ryzen 9 9955HX, which wins 14 of the 15 recorded head-to-head tests. The single Intel victory comes in Cinebench R23 single-core, where the Intel Core 9 273PTE scores 2886 against AMD's 2174, a lead of 24.7%. This indicates that the Intel part has a strong single-threaded burst capability, likely related to its 5.50 GHz boost clock.

In Cinebench R15 multicore, the AMD scores 5905 versus Intel's 2060, a delta of 186.7%. The Cinebench R23 multicore test shows a similar pattern: AMD scores 37159, Intel scores 20445, a delta of 81.8%. These results confirm that the AMD's 16 cores and 32 threads provide a massive multi-threaded advantage over Intel's 12 cores and 24 threads in rendering workloads.

PassMark tests reinforce this pattern across a wide range of operations. In integer math, the AMD scores 212598 versus 82411, a 158% lead. Floating point math shows AMD at 136682 against Intel's 60673, a 125.3% lead. Extended instructions show the largest gap: AMD scores 57946 versus Intel's 15952, a delta of 263.3%. Data compression results are also lopsided, with AMD at 731998 versus Intel's 258704, a 182.9% advantage. Data encryption shows AMD at 37330 versus 14253, a 161.9% lead.

Prime number finding favors the AMD by 102.1% (287 versus 142). Random string sorting shows AMD at 77890 versus Intel's 28973, a 168.8% lead. The PassMark multithread score has AMD at 56171 versus 24054, a 133.5% advantage. Physics simulation also favors AMD, with scores of 2720 versus 1917, a 41.9% lead. In the single-thread PassMark test, AMD wins with 4393 versus 3433, a 28% advantage, which contrasts with the Cinebench R23 single-core result where Intel leads. This suggests the AMD's single-thread performance is competitive and often ahead, depending on the benchmark methodology.

Cinebench R15 single-core shows AMD at 336 versus Intel's 290, a 15.9% lead. The pattern is clear: the AMD wins nearly every test, often by large margins, and the only Intel win is a single Cinebench R23 single-core test. The magnitude of AMD's wins in multi-threaded and math-heavy tests is particularly large, indicating a fundamental throughput advantage.

Where Each One Wins

The AMD Ryzen 9 9955HX is the clear winner in nearly every measured workload. Its 16 cores and 32 threads deliver a 186.7% advantage in Cinebench R15 multicore and an 81.8% advantage in Cinebench R23 multicore. For rendering, video encoding, or any heavily parallel task, the data shows a massive performance lead. The AMD also dominates in integer math (158% lead), floating point math (125.3% lead), and extended instructions (263.3% lead), making it the stronger choice for scientific computation, data processing, and encryption workloads. Its PassMark multithread score of 56171 versus 24054 confirms a 133.5% advantage in general multithreaded throughput.

The AMD also wins in single-thread performance in PassMark (28% lead) and Cinebench R15 single-core (15.9% lead), showing that it is not merely a multi-core specialist. Its higher base clock of 2.50 GHz and larger L3 cache likely contribute to these wins. The AMD's 96th percentile ranking versus Intel's 82nd percentile further underscores its overall standing in the database.

The Intel Core 9 273PTE wins only in Cinebench R23 single-core, with a 24.7% lead over the AMD. This indicates that for short, lightly threaded workloads that rely on a single core's peak boost, the Intel part can deliver higher performance. Its 5.50 GHz boost clock and 2 MB L2 per core may help in such scenarios. Additionally, the Intel supports both DDR4 and DDR5 memory, offering more platform flexibility for desktop builds that reuse older memory. Its lower TDP of 45 W versus 55 W means it consumes less power on paper, which could matter in thermally constrained desktop systems.

For workloads such as single-threaded legacy applications, certain simulation tasks, or memory-flexible desktop configurations, the Intel provides specific advantages. However, the breadth of the AMD's wins, across 14 of 15 benchmarks, makes it the dominant performer in the recorded data. The Intel's single victory is narrow in scope, limited to one Cinebench version, while the AMD's victories include both multi-threaded and single-threaded tests, with margins ranging from 15.9% to 263.3%.
