AMD Ryzen 5 7600X3D vs Intel Core i5-12450HX Comparison

The AMD Ryzen 5 7600X3D and Intel Core i5-12450HX represent two fundamentally different approaches to CPU design, and the benchmark data reflects a decisive performance gap. The Ryzen 5 7600X3D wins all 17 head-to-head comparisons, with the magnitude of those victories varying dramatically by workload. The Intel part, while competitive in absolute terms with an average benchmark score of 24,576, trails the AMD processor's 24,728 average by a narrow 0.6% margin in the overall dataset. However, this aggregate figure masks the lopsided nature of individual test results, where the AMD chip often leads by double-digit percentages.

Head-to-Head Benchmarks

The most striking result is in Cinebench R23 multi-core, where the Ryzen 5 7600X3D scores 21,758 against the i5-12450HX's 11,390. That is a 91% advantage, the largest delta in the entire comparison. This is not a marginal win; it is a near-doubling of throughput in a heavily multithreaded rendering workload. The Cinebench R15 and R20 multi-core tests tell a similar story, with the AMD part leading by 45% in both (2,193 vs 1,512 and 9,138 vs 6,304 respectively). These consistent 45% margins across Cinebench versions indicate a structural advantage in sustained multi-core performance rather than a workload-specific anomaly.

Single-core results are less dramatic but still clearly favor AMD. The Ryzen 5 7600X3D posts 3,071 in Cinebench R23 single-core versus 2,119 for Intel, a 44.9% lead. In Cinebench R15 and R20 single-core, the deltas are 45.1% and 45% respectively. PassMark's single-thread test narrows the gap considerably, with AMD scoring 3,605 against Intel's 3,340, a 7.9% advantage. This suggests that Intel's architecture is relatively stronger in legacy single-threaded code, but the AMD core still holds the edge across the board.

The most extreme outlier is PassMark's find prime numbers test, where AMD scores 234 against Intel's 54. That is a 333.3% delta, indicating a massive difference in integer-heavy, branch-predictor-dependent workloads. PassMark physics shows a 167.6% lead for AMD (2,906 vs 1,086), which is another workload where the Ryzen's architecture excels. Extended instructions see a 52.6% gap (21,108 vs 13,832), while random string sorting is 47.2% ahead (34,318 vs 23,306).

Some workloads are much closer. Floating-point math shows only a 2.7% advantage for AMD (44,289 vs 43,126), suggesting that the Intel part's FPU is nearly as capable as the AMD equivalent. Data compression is 28.2% ahead for AMD (281,665 vs 219,707), and integer math shows a 29.1% gap (73,804 vs 57,189). Data encryption is 34.1% in AMD's favor (16,237 vs 12,110). The PassMark multithread score is 41.5% higher for AMD (25,855 vs 18,274), which aligns with the Cinebench multi-core results.

The i5-12450HX has no wins in any of the 17 head-to-head tests. Its best showing is in floating-point math, where it comes within 2.7% of the AMD part. Its worst is in prime number finding, where it achieves less than a quarter of AMD's score.

Q: How do these CPUs compare to their nearest rivals?

A: The AMD Ryzen 5 7600X3D sits within 0.6% of the Intel Core 5 210H (24,872) and 0.1% of the AMD Ryzen 7 5700X3D (24,709). The Intel i5-12450HX is within 0.1% of the Intel Core i5-11600 (24,563) and 0.5% of the AMD EPYC 9654P (24,465).

Architecture Differences

The two processors are built on completely different architectures and process nodes. The AMD Ryzen 5 7600X3D uses the Zen 4 architecture, codenamed Raphael, fabricated on a 5 nm process at TSMC. It contains 11,270 million transistors on a 71 mm² die. In contrast, the Intel Core i5-12450HX uses Alder Lake architecture, codenamed Alder Lake-HX, on Intel's 10 nm process with a 215 mm² die size. The transistor count for Intel is not listed.

Core configuration differs significantly. The AMD part has 6 cores and 12 threads, while the Intel part has 8 cores and 12 threads. This means the Intel chip has more physical cores but the same thread count, indicating that Intel uses a hybrid architecture with performance and efficiency cores, though the data does not specify the P-core/E-core split. The AMD chip uses a uniform core design.

Cache hierarchy is where the AMD part gains its massive multi-core advantage. The Ryzen 5 7600X3D has 96 MB of shared L3 cache, compared to just 12 MB for the Intel part. This 8x difference in L3 cache is the primary driver of the performance gap in cache-sensitive workloads like Cinebench and PassMark physics. The L1 cache is 64 KB per core for AMD versus 80 KB per core for Intel. The L2 cache is 1 MB per core for AMD and 1.25 MB per core for Intel.

Memory support also differs. The AMD part supports DDR5 memory only, with a dual-channel bus and 83.2 GB/s bandwidth. The Intel part supports both DDR4 and DDR5, also dual-channel, but its bandwidth is not listed in the data. The AMD part supports ECC memory, while the Intel part does not.

PCIe connectivity is similar but not identical. AMD provides Gen 5 with 24 lanes (CPU only), while Intel provides Gen 5 with 20 lanes (CPU only). Integrated graphics differ as well, with AMD using Radeon Graphics and Intel using UHD Graphics 710.

The AMD part is built for desktop platforms using Socket AM5, while the Intel part is a mobile processor using BGA 1964. The Intel part has an unlocked multiplier, while AMD's is locked. The Intel part was released on May 9, 2022, while the AMD part was released on August 29, 2024.

The Verdict

The data is unambiguous: the AMD Ryzen 5 7600X3D is the superior processor in every measured benchmark. With 17 wins and 0 losses, it outperforms the Intel Core i5-12450HX across all tested workloads. The average benchmark score of 24,728 for AMD versus 24,576 for Intel confirms this, though the 0.6% aggregate difference understates the per-test gaps.

For multi-threaded workloads, the AMD part is transformative. The 91% lead in Cinebench R23 multi-core and 41.5% lead in PassMark multithread indicate that the Ryzen 5 7600X3D is in a different performance class for rendering, simulation, and content creation. The 96 MB of L3 cache provides a massive advantage in cache-bound workloads, as evidenced by the 333.3% lead in prime number finding and 167.6% lead in physics.

For single-threaded tasks, the AMD part still wins, but the margin shrinks. The 7.9% lead in PassMark single-thread suggests that the Intel Alder Lake core is competitive in lightly threaded scenarios, though it cannot match the AMD Zen 4 core's efficiency.

The Intel part's only redeeming quality is its proximity in floating-point math, where it trails by just 2.7%. This is a niche result that does not compensate for the deficits elsewhere.

Users who prioritize multi-core performance, cache-sensitive workloads, or energy efficiency (AMD's 65W TDP vs Intel's 55W TDP is notable, though the AMD part delivers much higher performance per watt in these benchmarks) should choose the AMD Ryzen 5 7600X3D. Users who require a mobile form factor (BGA 1964 socket) or who need DDR4 memory support might consider the Intel part, but they would be accepting a significant performance penalty. The data provides no workload category where the Intel i5-12450HX is the better choice.
