AMD Ryzen 7 8840HS vs Intel Core i5-13450HX Comparison

The Verdict

The data separates these two mobile processors by workload character, not by overall capability. The Intel Core i5-13450HX and AMD Ryzen 7 8840HS both sit at the 84th percentile among all CPUs in the database, and their average benchmark scores are close: 34333 for the Intel part versus 33667 for the AMD part, a gap of roughly 2%. The Intel chip wins 8 of the 15 recorded head-to-head tests, while the AMD chip wins 7. This is a split decision.

The Intel Core i5-13450HX is the pick for sustained multithreaded compute and physics-style loads. Its Cinebench R23 multi-core score of 16797 beats the Ryzen 7 8840HS's 13082 by 28.4%. In Cinebench R15 multi-core, the Intel advantage is 2503 versus 2045, a 22.4% lead. PassMark physics shows the largest single delta: 1504 for Intel versus 1149 for AMD, a 30.9% margin. If the workload is rendering, simulation, or any task that scales across many threads, the Intel part is the clear choice.

The AMD Ryzen 7 8840HS counters in single-thread agility and specific instruction-heavy tasks. Its Cinebench R15 single-core score is 270 versus 248, an 8.1% lead. In PassMark integer math, AMD leads 90382 to 83209 (7.9%), and in extended instructions it leads 20714 to 19083 (7.9%). Random string sorting favors AMD by 35517 to 31940, a 10.1% margin. For users whose daily tasks are single-thread bound or involve encryption and string manipulation, the AMD part is the better fit.

The power envelope tells a secondary story: the Intel part has a 55 W TDP, while the AMD part is rated at 28 W. That difference often influences chassis design and sustained performance, but the benchmark results in the database do not include power measurements, so conclusions about efficiency must be drawn from the spec sheet alone. The verdict is simple: pick Intel for heavy multi-core throughput, pick AMD for single-thread and integer/string workloads. Both are 84th percentile, so neither is a weak choice.

Head-to-Head Benchmarks

The head-to-head data shows 15 tests, with Intel winning 8 and AMD winning 7. The margins vary from razor-thin to dominant.

The Intel Core i5-13450HX wins the multi-core Cinebench tests by wide margins. In Cinebench R15 multi-core, it scores 2503 versus 2045, a 22.4% advantage. In Cinebench R23 multi-core, it scores 16797 versus 13082, a 28.4% advantage. The PassMark multithread test is very close: Intel scores 25084, AMD scores 24990, a 0.4% edge for Intel. PassMark physics is the biggest Intel win: 1504 versus 1149, a 30.9% gap. In integer-heavy tasks, Intel wins floating point math (61776 versus 52582, a 17.5% lead) and find prime numbers (83 versus 79, a 5.1% lead). Data compression also favors Intel slightly: 305990 versus 292888, a 4.5% win.

The AMD Ryzen 7 8840HS wins the single-core and specific instruction tests. In Cinebench R15 single-core, AMD leads 270 versus 248, an 8.1% margin. In PassMark single-thread (recorded twice), AMD leads 3626 versus 3553, a 2% edge. The AMD chip also wins PassMark integer math (90382 versus 83209, a 7.9% lead), extended instruction (20714 versus 19083, also 7.9%), and random string sorting (35517 versus 31940, a 10.1% margin). Data encryption goes to AMD: 17650 versus 16632, a 5.8% win.

The Cinebench R23 single-core test is the closest result: Intel wins 1746 versus 1737, a 0.5% delta. This is the only single-core test that Intel wins. The overall picture is that Intel dominates in multi-thread rendering and physics, while AMD dominates in single-thread and string/encryption operations. The Intel margin in multi-thread (up to 30.9%) is larger than the AMD margin in single-thread or string tests (up to 10.1%), which explains why Intel wins the overall average benchmark score by 2%.

The data shows a typical tradeoff: Intel's higher core count and larger cache deliver strong multi-thread performance; AMD's higher clocks (5.10 GHz versus 4.60 GHz) and more efficient process (4 nm versus 4 nm) deliver better single-thread and integer tasks. The 28 W TDP of the AMD part makes it a more efficient choice for light workloads, while the 55 W TDP of the Intel part gives it headroom for heavy multi-thread loads. Each CPU is the better tool for a different job.
