Intel Core i5-12450H

The Intel Core i5-12450H is a mobile processor from the Intel Core 12th Gen series, built on the Alder Lake-H architecture at Intel’s 10 nm process node. It has 8 cores and 12 threads, a base clock of 2000.00 MHz, a boost clock of 4.40 GHz, and a TDP of 45. The chip uses the Intel BGA 1744 socket, supports DDR4 and DDR5 memory on a dual-channel bus, and provides Gen 4 PCIe with 20 lanes from the CPU. It includes Intel UHD Graphics as its integrated GPU. The database places it in the 75th percentile of all CPUs, with an average benchmark score of 17475.

Benchmark Performance

The average benchmark score of 17475 puts the Core i5-12450H in the 75th percentile among all processors in the database. That means it sits above roughly three-quarters of the CPUs tracked, which is a strong mid-pack result for a mobile part. Its nearest rival by average score is the AMD Ryzen 3 PRO 5355GE, with an average score of 17482 and a deltaPct of 0. The Ryzen 5 4600G follows with 17489 and a deltaPct of -0.1. The Intel Core i3-14100T and i3-13100F are slightly higher at 17636 and 17665, with deltas of -0.9 and -1.1 respectively. In short, all four nearest rivals sit within about a point or two of the i5-12450H in aggregate score, so the overall performance tier is very tightly packed.

Looking at specific benchmark suites, the 3DMark results show a clear scaling pattern. The single-thread score is 912, the 2-thread score is 1743, the 4-thread score is 3091, and the 8-thread score is 4233. The 16-thread score climbs to 5001, and the max-thread score is 5020. The near-flat difference between the 16-thread and max-thread results indicates that the chip’s multi-threaded headroom is already largely tapped by the 16-thread run. In Cinebench, the R23 multi-core score is 13822 against a single-core score of 1951. The R20 multi-core score is 5805 with a single-core score of 819, and the older R15 test shows a multi-core score of 1393 with a single-core score of 196. These Cinebench results reinforce the pattern: this is a processor with meaningful multi-core capacity and moderate per-core performance.

PassMark results add another perspective. The multithread score is 16265, while the single-thread score is 3306. Integer math scores 54782, floating point math scores 40568, and extended instructions score 11992. Data encryption scores 10832, data compression scores 195132, and random string sorting scores 20838. The physics test scores 883, and find prime numbers scores 46. The large gap between integer math and floating point math suggests that integer-heavy productivity code extracts more from this CPU than floating-point-heavy code. The data compression score is particularly strong, indicating that file archiving and similar compression tasks are well served.

Power and Thermals

The Core i5-12450H carries a TDP of 45, which places it in the performance-mobile power class. That is a higher thermal envelope than typical low-power ultraportable parts, but it is still a mobile-oriented figure. The socket is Intel BGA 1744, so this is not a drop-in desktop processor; cooling must be designed around a laptop motherboard. The 10 nm process and 217 mm² die size define the physical side of the thermal equation. A 45 TDP part generates enough heat that a laptop manufacturer needs active cooling rather than a purely passive solution. Sustaining the 4.40 GHz boost clock under load will depend on the cooling solution and chassis airflow. The integrated UHD Graphics also shares the same package, so the thermal solution must account for iGPU load as well as CPU load. In practical terms, this is a chip for 45-class performance laptops, not for fanless designs or ultra-thin passive systems.

How It Compares

The AMD Ryzen 3 PRO 5355GE is the closest rival by average benchmark score, posting 17482 against the i5-12450H’s 17475, with a deltaPct of 0. The two processors are effectively a statistical tie in aggregate performance. The choice between them would come down to platform features and system integration, because the benchmark numbers do not meaningfully separate them.

The AMD Ryzen 5 4600G scores 17489, with a deltaPct of -0.1 against the i5-12450H. That is a negligible margin. A one-tenth of a percent difference in average score is far smaller than run-to-run variation in most real workloads. Users should not expect a practical performance difference between these two in ordinary use.

The Intel Core i3-14100T posts an average score of 17636, with a deltaPct of -0.9. That puts the i5-12450H slightly behind, but still within a single percentage point. The i5 has more cores and threads, so in workloads that scale past the i3’s thread count, the i5 may close or reverse the gap. The aggregate score alone does not capture that workload-specific behavior.

The Intel Core i3-13100F is the farthest of the four rivals, with an average score of 17665 and a deltaPct of -1.1. Even at this largest gap, the i5-12450H trails by barely over one percent in aggregate benchmark score. This is not a class-level difference. It is a close grouping where individual workload performance, power characteristics, and platform availability matter more than the average score.

Single-Thread vs Multi-Thread Behavior

The 3DMark data provides a useful scaling curve. Single-thread scores 912, 2-thread scores 1743, 4-thread scores 3091, 8-thread scores 4233, and 16-thread scores 5001. The jump from 4 to 8 threads is large, and the move from 8 to 16 threads adds another meaningful gain. The max-thread score of 5020 is almost identical to the 16-thread score, which shows that the processor has limited additional headroom beyond what a 16-thread workload can extract. Since the chip has 12 threads, the 16-thread benchmark already covers the processor’s full thread count, and the max-thread result confirms that there is not a hidden pool of extra multi-threaded performance.

Cinebench tells a similar story. The R23 multi-core score of 13822 is several times the single-core score of 1951. The R20 pair is 5805 multi-core versus 819 single-core, and the R15 pair is 1393 multi-core versus 196 single-core. Across all three Cinebench versions, the multi-core result dominates the single-core result. PassMark also shows this split: the multithread score is 16265, while the single-thread score is 3306.

For real workloads, this means lightly threaded tasks such as web browsing, office document work, and general system responsiveness rely primarily on the single-thread score. The 1951 Cinebench R23 single-core score and 3306 PassMark single-thread score are reasonable in the context of its closest rivals, which sit at nearly the same average benchmark level. Heavily threaded workloads, including rendering, video encoding, data compression, and virtualization, will push toward the multi-core scores. The data compression score of 195132 and multithread score of 16265 are strong indicators that this chip handles parallel productivity workloads well. The integer math score of 54782 also suggests good throughput for integer-heavy parallel code. In contrast, workloads that depend on a few fast cores will not extract the full multi-core advantage.

Who Should Consider It

The Core i5-12450H is a sensible choice for users who need an 8-core, 12-thread mobile processor with a 45 TDP class and integrated graphics. If the workload is heavily threaded, the Cinebench R23 multi-core score of 13822 and PassMark multithread score of 16265 indicate solid performance for rendering, compression, and similar parallel tasks. The data compression score of 195132 makes it particularly well suited for file archiving and compression-heavy work. Integer math performance is also strong at 54782, so developers and analysts working with integer-heavy workloads may find it capable. Floating point math is lower at 40568, so pure floating-point-heavy calculation is not the chip’s best area, but it is still in the same performance neighborhood as its nearest rivals.

For office and general productivity, the single-thread scores are adequate. The PassMark single-thread score of 3306 and Cinebench R23 single-core score of 1951 are enough for responsive everyday use. The integrated UHD Graphics means the system can output video without a separate GPU, which is useful for office machines and thin-and-light productivity laptops. For gaming, the CPU side is moderate, but the integrated UHD Graphics will be the limiting factor for visually intensive games. The CPU’s single-thread score can handle game logic reasonably well, but graphics-heavy gaming workloads will require a laptop with a stronger GPU solution. Users whose primary need is maximum single-thread performance should note that the i5-12450H sits at a 0.0 deltaPct versus its closest rival and trails the Intel Core i3-13100F by only 1.1%, so it is not a single-thread outlier. Users whose primary need is multi-threaded throughput will find the 8-core, 12-thread configuration and the benchmark results more compelling.
