AMD Ryzen 7 8745HX vs Intel Core i9-14901E Comparison

The AMD Ryzen 7 8745HX and Intel Core i9-14901E are both 8-core, 16-thread processors, but they target different market segments and exhibit distinct performance profiles. The data shows a clear split: the Intel part dominates in raw computational throughput for specific workloads, while the AMD part leads in several memory and data-handling tasks. The following analysis breaks down where each processor delivers its strongest results based on recorded benchmark data.

Where Each One Wins

The head-to-head benchmark results reveal a near-even split, with Intel securing 6 wins and AMD taking 5. However, the margin of victory in each category tells a more nuanced story. Intel’s wins are often decisive, particularly in floating-point math, physics, and single-threaded tasks. AMD’s wins, while fewer in count, include some very large margins in specific workloads.

Intel Core i9-14901E wins in the PassMark physics test with a score of 3041 against AMD’s 1681, a massive 44.7% advantage. This indicates a significant lead in simulations and physics-based calculations. Intel also dominates floating-point math, scoring 81089 versus 61972, a 23.6% edge, which is important for scientific computing and 3D rendering. The single-thread score of 4354 for Intel is 10.9% higher than AMD’s 3879, showing an advantage in lightly threaded applications and legacy code. Intel also wins in integer math (112736 vs 100328, an 11% lead) and prime number finding (189 vs 159, a 15.9% lead).

AMD Ryzen 7 8745HX wins in data compression with a score of 363759 versus 288777, a 26% advantage, indicating superior performance in file archiving and database workloads. It also leads in extended instructions (27638 vs 17249, a 60.2% lead), which covers newer instruction set extensions. The AMD part wins in random string sorting (44494 vs 39138, a 13.7% lead) and data encryption (21840 vs 18571, a 17.6% lead). Its multi-thread score of 31517 is 4% higher than Intel’s 30298, showing a slight overall multi-threaded advantage despite losing several individual multi-threaded subtests.

Architecture Differences

The two processors are built on fundamentally different architectures. The AMD Ryzen 7 8745HX uses the Zen 4 architecture with the Dragon Range codename, fabricated on a 5 nm process at TSMC. It integrates 6,570 million transistors on a 71 mm² die. The Intel Core i9-14901E uses the Raptor Lake architecture with the Raptor Lake-R codename, fabricated on a 10 nm process at Intel, with a die size of 257 mm². This process difference explains why AMD can fit a similar number of cores in a much smaller physical area.

Cache configurations differ substantially. AMD provides 64 KB of L1 and 1 MB of L2 per core, with 32 MB of shared L3 cache. Intel provides a larger 80 KB of L1 and 2 MB of L2 per core, with 36 MB of shared L3 cache. The larger L3 cache on Intel (36 MB vs 32 MB) and double the L2 cache per core likely contribute to its lead in single-threaded and physics-based workloads.

Memory support also diverges. AMD supports DDR5 memory exclusively with a dual-channel bus, delivering a measured memory bandwidth of 83.2 GB/s. Intel supports both DDR4 and DDR5 on a dual-channel bus, but its memory bandwidth is not recorded in the database. The AMD part does not support ECC memory, while Intel does. PCIe connectivity differs as well: AMD offers Gen 5 with 28 lanes (CPU only), while Intel offers Gen 5 with 16 lanes (CPU only).

The market segments and sockets are entirely different. AMD is a mobile processor using AMD Socket FL1, with a TDP of 55 and an unlocked multiplier. Intel is a desktop processor using Intel Socket 1700, with a TDP of 65 and a locked multiplier. The integrated graphics also vary: AMD uses Radeon 610M, while Intel uses UHD Graphics 770. The release dates differ, with Intel launching in June 2024 and AMD in April 2025.

The Verdict

The data indicates that neither processor is universally superior, and the choice depends entirely on the target workload. For applications that are heavily single-threaded or rely on floating-point operations, physics simulation, or integer math, the Intel Core i9-14901E is the stronger option. Its 44.7% lead in physics and 23.6% lead in floating-point math are substantial. The 10.9% single-thread advantage also makes it better suited for legacy applications that cannot utilize multiple cores effectively.

For modern multi-threaded workloads that involve data compression, encryption, or string manipulation, the AMD Ryzen 7 8745HX holds the edge. Its 60.2% lead in extended instructions is particularly notable, suggesting it handles newer instruction set extensions more efficiently. The 26% lead in data compression and 17.6% lead in encryption make it a better fit for database servers, file compression tools, and security-related tasks. The 4% multi-thread score advantage, though small, confirms its overall multi-threaded capability.

The average benchmark score in the database places AMD at 60104, while Intel is at 37911. However, this metric is misleading because it averages across different benchmark types where Intel’s Cinebench scores are included, which are not present for AMD. The head-to-head PassMark comparisons are the more reliable indicator. AMD’s percentile ranking of 92 versus Intel’s 86 shows AMD is better positioned relative to all CPUs in the database, but this is partly due to its mobile efficiency.

The Intel part is a desktop processor with a higher TDP of 65, allowing it to sustain higher clocks (5.60 GHz boost versus 5.10 GHz for AMD) and likely better sustained performance in desktop environments. The AMD part is a mobile processor with a lower TDP of 55, designed for laptops where power efficiency is critical. If the workload is mobile and power-sensitive, AMD is the only option. If desktop performance in physics, floating-point, or single-threaded tasks is the priority, Intel is the clear choice.

Head-to-Head Benchmarks

The most significant win for AMD is in extended instructions, where it scores 27638 versus Intel’s 17249, a 60.2% advantage. This is the largest percentage difference in the entire comparison and suggests AMD’s Zen 4 architecture handles AVX-512 or similar instruction sets far more efficiently. The second-largest AMD win is in data compression, 363759 versus 288777, a 26% lead, indicating a strong advantage in memory bandwidth utilization and cache efficiency for this workload.

Intel’s most significant win is in physics, scoring 3041 versus AMD’s 1681, a 44.7% lead. This is nearly half again as fast as AMD in physics simulation. Intel also wins decisively in floating-point math, 81089 versus 61972, a 23.6% lead, and in integer math, 112736 versus 100328, an 11% lead. These three wins show Intel’s raw arithmetic processing power is substantially higher.

In the multi-thread score, AMD wins by a narrow margin, 31517 versus 30298, a 4% lead. This is the closest result in the comparison. Intel wins the single-thread score by 10.9% (4354 vs 3879), but AMD wins random string sorting by 13.7% (44494 vs 39138) and data encryption by 17.6% (21840 vs 18571). Intel wins prime number finding by 15.9% (189 vs 159).

The pattern is clear: Intel excels at pure number crunching (physics, floating-point, integer, prime finding) and single-threaded tasks, while AMD excels at data movement tasks (compression, encryption, string sorting, extended instructions) and maintains a slight multi-thread score edge. The overall win count is 6 for Intel and 5 for AMD, but the magnitude of AMD’s wins in extended instructions and compression, combined with its multi-thread victory, makes it a competitive option despite the count disadvantage.
