The recorded head-to-head data covers 13 benchmark comparisons between the AMD Ryzen 7 8840HX and the Intel Core 7 253PTE. The AMD processor wins 12 of those comparisons, while the Intel part takes a single victory. The scale of those wins, however, is not uniform, and the one Intel victory is decisive.

The most dramatic AMD advantage appears in PassMark's find prime numbers test. The Ryzen 7 8840HX scores 304 against Intel's 82, a delta of 270.7%. This is the largest percentage gap in the entire comparison set. Extended instructions also show a massive split, with AMD at 36,527 versus Intel at 17,099, a 113.6% advantage. Random string sorting follows closely, AMD scoring 57,971 against Intel's 28,227, a 105.4% lead. Data encryption shows a 93% gap, with AMD at 29,919 and Intel at 15,500. Data compression delivers an 80% delta, AMD at 496,427 versus Intel at 275,828.

Multi-threaded workloads show substantial but less extreme AMD margins. PassMark multithread scores 41,732 for AMD versus 25,031 for Intel, a 66.7% lead. Physics testing shows a 65.8% difference, AMD at 2,185 and Intel at 1,318. Floating point math favors AMD by 29.1%, with scores of 86,747 and 67,209. Integer math shows a 22.5% gap, AMD at 146,506 and Intel at 119,552. In Cinebench R23 multicore, AMD leads 25,265 to 21,276, an 18.7% margin.

The single-core picture is more nuanced. In Cinebench R23 singlecore, the Intel Core 7 253PTE wins outright, scoring 3,003 against AMD's 1,857, a 38.2% advantage. That is the only benchmark in the set where Intel leads. However, in PassMark single-thread testing, the AMD part wins by a narrow 4.3%, scoring 3,958 versus 3,794. The PassMark singlethread result repeats the same numbers and the same 4.3% delta. So the two processors split single-threaded performance depending on the test methodology, but the Intel lead in Cinebench R23 singlecore is far larger than the AMD lead in the PassMark single-thread tests.

Average benchmark scores place the AMD part at 71,797, which sits in the 94th percentile among all CPUs. The Intel part averages 34,962, in the 84th percentile. The nearest rivals for the AMD processor include the Intel Core Ultra 7 265KF at 71,910 (a 0.2% difference), the Intel Xeon 6517P at 72,350 (0.8% higher), and the Intel Xeon 6724P at 72,396 (0.8% higher). The Intel Core 7 253PTE sits near the Intel Core i7-13800H at 34,988 (0.1% higher), the Intel Core i9-12900HX at 35,003 (0.1% higher), and the AMD Ryzen 5 150 at 34,881 (0.2% lower).

Where Each One Wins

The AMD Ryzen 7 8840HX dominates in workloads that scale with core count, cache size, and parallel execution. The data shows 12 of 13 benchmark wins, with particularly large margins in encryption, compression, extended instruction sets, and prime number calculations. These are heavily parallel tasks that benefit from the AMD part's 12 cores and 24 threads. The Cinebench R23 multicore result, an 18.7% lead, confirms that even in a widely used rendering workload, the AMD processor holds a clear advantage.

The Intel Core 7 253PTE wins only in Cinebench R23 singlecore, and it wins there by a substantial 38.2%. This indicates that for lightly threaded workloads where a single core carries the load, the Intel processor delivers noticeably higher performance. The boost clock of 5.40 GHz on the Intel part, compared to 5.10 GHz on the AMD part, aligns with this single-core result.

The PassMark single-thread results complicate the picture slightly. The AMD processor edges Intel by 4.3% in both PassMark single-thread and PassMark singlethread tests. This suggests that the Intel single-core advantage is not universal across all single-threaded test types. The Cinebench R23 singlecore test may favor the Intel architecture more strongly than the PassMark single-thread methodology does.

For data compression, the AMD part scores 496,427 versus 275,828, an 80% lead. Data encryption shows a 93% gap. These are common server and workstation tasks, and the AMD processor handles them with far more headroom. The physics test, often indicative of simulation workloads, shows a 65.8% AMD advantage.

The Intel processor's higher memory bandwidth of 89.6 GB/s versus 83.2 GB/s for AMD does not translate into wins in any of the recorded benchmarks. The AMD processor's larger shared L3 cache of 64 MB versus 33 MB likely contributes to its dominance in data-heavy workloads.

Architecture Differences

The AMD Ryzen 7 8840HX uses the Zen 4 architecture under the codename Dragon Range. It is built on a 5 nm process at TSMC, with 13,140 million transistors and a die size of 2x 71 mm². The Intel Core 7 253PTE uses the Bartlett Lake codename on a 10 nm process at Intel's own foundry. No transistor count or die size is recorded for the Intel part.

The AMD generation is listed as Ryzen 7 (Zen 4, Dragon Range). The Intel generation is listed as Core 7 (Bartlett Lake). The AMD processor has no architecture field beyond Zen 4, while the Intel architecture field is null in the database.

The process node difference is significant: 5 nm for AMD versus 10 nm for Intel. This likely contributes to the AMD part's higher core count and larger L3 cache while maintaining a 55 watt TDP. The Intel part operates at a lower 45 watt TDP with fewer cores and a smaller cache.

The AMD processor uses a dual-die design with a combined die size of 2x 71 mm². The Intel processor has no die size data recorded. The AMD part's transistor count of 13,140 million is recorded, while the Intel part's transistor count is absent from the database.

The AMD processor is unlocked, allowing multiplier adjustment. The Intel processor is locked. This is an architectural difference that affects overclocking capability, although the database does not include overclocking benchmark results.

The Intel part supports ECC memory, which the AMD part does not. This positions the Intel processor for certain reliability-focused desktop workloads. The AMD part, despite being classified as Mobile, uses the same FL1 socket and Dragon Range design as other high-core-count mobile processors.

The Verdict

The recorded data presents a clear performance hierarchy. The AMD Ryzen 7 8840HX wins 12 of 13 head-to-head benchmarks, with an average score of 71,797 against Intel's 34,962. The AMD part sits in the 94th percentile of all CPUs, while the Intel part sits in the 84th. For multi-threaded workloads, rendering, compression, encryption, and math-heavy tasks, the AMD processor is the stronger choice by wide margins.

The Intel Core 7 253PTE has one clear strength: Cinebench R23 singlecore performance, where it beats AMD by 38.2%. It also has a higher boost clock of 5.40 GHz, ECC memory support, DDR4 and DDR5 compatibility, and a lower TDP of 45 watts. For users running lightly threaded applications that respond strongly to single-core speed, the Intel part holds a specific advantage.

The AMD processor counters with a 4.3% lead in PassMark single-thread tests, showing that the Intel single-core advantage does not extend to every single-threaded benchmark. The AMD part also offers more cores, more threads, double the L3 cache, and a smaller 5 nm process node.

The data indicates that the AMD Ryzen 7 8840HX is the higher-performing processor overall. The Intel Core 7 253PTE earns consideration only in scenarios where single-core Cinebench-style performance is the primary requirement and where ECC memory support or DDR4 compatibility is necessary. For all other recorded workloads, the AMD processor leads, often by margins exceeding 50%.
