Intel Core i7-12650HX vs Intel Core i7-13705H Comparison

Head-to-Head Benchmarks

The benchmark data reveals a fascinating split between these two mobile processors. The Intel Core i7-12650HX dominates the Cinebench suite, while the Intel Core i7-13705H counters with strong showings across several PassMark workloads. The overall win tally stands at 7 for the 13705H and 10 for the 12650HX, but the margins tell a more nuanced story.

The 12650HX delivers its most decisive blows in the Cinebench tests. In Cinebench R23 multi-core, it scores 19043 against the 13705H's 15998, a 16% advantage. The same 16% gap appears in R20 multi-core (7998 versus 6719), R15 multi-core (1919 versus 1612), and even single-core tests: R23 single-core shows 2688 versus 2258, again a 16% difference. This consistency across all six Cinebench tests suggests a fundamental throughput advantage for the older Alder Lake part in heavily threaded rendering workloads.

However, the 13705H fights back in the PassMark suite with several substantial wins. The largest margin comes in PassMark physics, where the 13705H scores 1854 against the 12650HX's 1152, a massive 60.9% advantage. PassMark find prime numbers also shows a significant gap: 116 versus 74, a 56.8% delta. These results indicate that the Raptor Lake chip handles certain computational patterns with far greater efficiency.

The remaining PassMark wins for the 13705H are narrower but still meaningful. Floating point math shows a 7.9% lead (63064 versus 58426), while multithreaded performance sits 8.4% ahead (24460 versus 22573). Integer math trails at 5% (85927 versus 81810), and data encryption shows a 6.5% edge (16324 versus 15325). Data compression rounds out the wins at 2.6% (273720 versus 266700).

The 12650HX also claims a few PassMark victories beyond the Cinebench sweep. Single-thread performance lands at 3637 versus 3483, a 4.2% lead. Random string sorting goes to the 12650HX by a slim 1.4% margin (29692 versus 29285). Extended instructions are essentially tied, with the 12650HX ahead by just 0.3% (15856 versus 15810).

What explains this bifurcation? The Cinebench results point to the 12650HX's higher boost clock of 4.70 GHz versus 5.00 GHz for the 13705H, but that alone does not justify a 16% sweep. The PassMark physics and prime number results, where the 13705H excels by 50% or more, suggest architectural differences in how each processor handles branch-heavy or memory-latency-sensitive code. The data does not reveal a single winner across all workloads; instead, it shows two very different performance profiles.

The single-core Cinebench wins also suggest better performance in lightly threaded scenarios where the workload is not memory-bound. The 12650HX also edges ahead in PassMark single-thread (4.2%) and random string sorting (1.4%), making it a solid pick for general desktop responsiveness and quick data manipulations.

The Intel Core i7-13705H wins in PassMark multithread (8.4%), integer math (5%), floating point math (7.9%), data encryption (6.5%), and data compression (2.6%). Its standout results in physics (60.9% ahead) and prime number computation (56.8% ahead) point to advantages in workloads involving complex branching, tight loops, or physics simulations. The 13705H appears better suited for scientific computing, financial modeling, or any application that heavily exercises integer or floating point arithmetic outside of render engines. Its higher L2 cache per core (2 MB versus 1.25 MB) likely plays a role in these wins.

The data suggests a workload-dependent split rather than a universal victor. Rendering and single-threaded productivity lean toward the 12650HX, while arithmetic-heavy and physics-based tasks lean toward the 13705H. The 12650HX also offers an unlocked multiplier for users who prefer manual tuning, though no overclocked benchmarks are available to assess the benefit.

The Verdict

Choosing between these two processors depends entirely on the intended workload. The Intel Core i7-12650HX is the superior option for users who prioritize Cinebench-style rendering and single-threaded performance. Its consistent 16% lead across all Cinebench tests, combined with a 4.2% PassMark single-thread advantage, makes it the stronger pick for 3D artists, video editors, and anyone running CPU-based renderers. The unlocked multiplier adds flexibility for enthusiasts, and the 55 W TDP suggests a more aggressive power envelope for sustained loads.

The Intel Core i7-13705H is the better choice for computational workloads that benefit from its architecture's strengths. The 60.9% physics lead and 56.8% prime number advantage are not trivial margins. Users running simulations, scientific calculations, or data processing tasks that involve heavy arithmetic will see meaningful gains. The 13705H also holds advantages in multithreaded PassMark (8.4%), floating point (7.9%), and encryption (6.5%), making it a versatile option for mixed productivity.

The average benchmark scores place the 13705H slightly ahead overall (32076 versus 31290), and both sit at the 82nd percentile. The database's nearest rivals list reinforces this parity: the 13705H is within 0.5% of several comparable chips, and the 12650HX similarly trades within 0.6% of its nearest competitors. Neither processor dominates the other in aggregate.

For rendering and single-threaded tasks, the 12650HX is the data-backed recommendation. For physics, arithmetic, and encryption-heavy workloads, the 13705H is the clear winner. The 13705H's newer release date and higher boost clock suggest it may age better, but the 12650HX's Cinebench dominance cannot be ignored. The verdict is a split decision that respects each processor's distinct strengths.
