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

The Verdict

The AMD Ryzen 7 8745HX and Intel Core i9-14901KE are both 8-core, 16-thread processors, but they serve entirely different segments. The AMD part is a mobile chip, built for laptops, while the Intel part is a desktop chip, built for full-size systems. The database records a benchmark score for the AMD processor, placing it in the 92nd percentile of all CPUs, while the Intel processor has no recorded benchmark scores, placing it in the 50th percentile.

For workloads where the AMD processor has data, it is a high performer. Its average benchmark score of 60,104 places it alongside desktop-class rivals like the Intel Core i9-14900F (which scores 60,008, a 0.2% difference) and the AMD Ryzen 9 7945HX (which scores 60,099, a 0% difference). This indicates that the mobile chip is not a compromise in raw throughput. The Intel part, lacking any recorded measurements, cannot be positioned in the same way. The data suggests that for users who need a powerful mobile processor, the AMD Ryzen 7 8745HX is the only option with verified performance. For desktop users, the Intel Core i9-14901KE offers a different feature set, including ECC memory support, but its performance profile is unmeasured in this database.

Architecture Differences

The two processors are built on fundamentally different architectures and process nodes. The AMD Ryzen 7 8745HX uses the Zen 4 architecture, codenamed Dragon Range, and is fabricated on a 5 nm process by TSMC. The Intel Core i9-14901KE uses the Raptor Lake architecture, codenamed Raptor Lake-R, and is fabricated on a 10 nm process by Intel. This difference in node size is significant; the AMD chip's smaller process node typically allows for higher efficiency, though the database does not include direct power consumption measurements for comparison.

The cache hierarchies differ notably. The AMD processor has 64 KB of L1 cache per core and 1 MB of L2 cache per core, with 32 MB of shared L3 cache. The Intel processor has a larger 80 KB of L1 cache per core and 2 MB of L2 cache per core, with a larger 36 MB of shared L3 cache. The Intel part therefore has more total cache, which can benefit certain workloads that require large working sets.

Memory support also diverges. The AMD chip supports only DDR5 memory on a dual-channel bus, with a recorded memory bandwidth of 83.2 GB/s. The Intel chip supports both DDR4 and DDR5 memory on a dual-channel bus, but the database does not list a memory bandwidth figure for it. The Intel processor also supports ECC memory, while the AMD processor does not. This makes the Intel part suitable for error-sensitive tasks like server or workstation use, while the AMD part is a mobile consumer part.

The integrated graphics differ as well. The AMD processor uses a Radeon 610M, while the Intel processor uses UHD Graphics 770. The database does not provide benchmark scores for either integrated GPU, so no performance comparison is possible. The PCIe support is also different: the AMD processor offers Gen 5 with 28 lanes (CPU only), while the Intel processor offers Gen 5 with 16 lanes (CPU only). This gives the AMD part more expansion headroom for multiple GPUs or NVMe drives in a mobile platform.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results for these two processors. The Intel Core i9-14901KE has an empty benchmark array, and the head-to-head section is blank. Consequently, there are no recorded wins for either part in a direct comparison.

However, the AMD Ryzen 7 8745HX has a full suite of PassMark measurements. Its single-thread score is 3,879, and its multithread score is 31,517. In specific workloads, it scores 363,759 in data compression, 21,840 in data encryption, 27,638 in extended instructions, 159 in finding prime numbers, 61,972 in floating point math, 100,328 in integer math, 1,681 in physics, and 44,494 in random string sorting. These numbers show a processor that is strong in both integer and floating point operations, with a particularly high score in data compression.

The Intel Core i9-14901KE has no such scores in the database. Without recorded measurements, the data cannot indicate where it wins or loses against the AMD part. The only available comparison is architectural: the Intel chip has a higher base clock of 3.80 GHz and a higher boost clock of 5.80 GHz, versus the AMD's 3.60 GHz base and 5.10 GHz boost. These clock differences suggest the Intel part may have an advantage in lightly threaded tasks, but this is not confirmed by benchmark data.

Specification Differences

The two processors differ in several key specifications. The AMD Ryzen 7 8745HX has a base clock of 3.60 GHz and a boost clock of 5.10 GHz, while the Intel Core i9-14901KE has a base clock of 3.80 GHz and a boost clock of 5.80 GHz. The Intel part clocks higher on both ends.

The thermal design power (TDP) differs substantially. The AMD chip has a TDP of 55 watts, while the Intel chip has a TDP of 125 watts. This indicates the Intel processor requires significantly more power and cooling, which aligns with its desktop market segment versus the AMD's mobile segment.

The sockets are incompatible. The AMD processor uses AMD Socket FL1, while the Intel processor uses Intel Socket 1700. The process nodes differ: 5 nm for AMD, 10 nm for Intel. The die size also differs: the AMD chip is 71 mm², while the Intel chip is 257 mm². The transistor count is only listed for the AMD part at 6,570 million; the Intel part's transistor count is not recorded.

Memory support differs: the AMD chip supports only DDR5, while the Intel chip supports DDR4 and DDR5. The AMD chip has a recorded memory bandwidth of 83.2 GB/s; the Intel chip has no recorded memory bandwidth. ECC memory support is present on the Intel chip but absent on the AMD chip. PCIe lanes differ: 28 lanes for AMD, 16 lanes for Intel, both Gen 5.

The market segments are different: the AMD processor is a mobile part, while the Intel processor is a desktop part. The release dates differ: the AMD chip was released on 2025-04-22, while the Intel chip was released on 2024-06-30. Both processors have unlocked multipliers, allowing overclocking. Both are currently in active production.

Where Each One Wins

Based strictly on the recorded data, the AMD Ryzen 7 8745HX wins where it has measurements. Its average benchmark score of 60,104 places it in the 92nd percentile of all CPUs, and it competes directly with desktop-class processors like the Intel Core i9-14900F and AMD Ryzen 9 7945HX. This suggests that for mobile users who need high multithreaded performance, the AMD chip is a verified strong choice. Its 55-watt TDP also indicates it can operate within the power envelope of a laptop, making it suitable for portable workstations.

The Intel Core i9-14901KE wins on specification advantages where the data allows. It has higher base and boost clocks, which may translate to better single-threaded responsiveness, though no benchmark confirms this. It supports ECC memory, which is a requirement for certain professional and server-like workloads. It also supports both DDR4 and DDR5 memory, offering flexibility in system building. Its larger L3 cache (36 MB vs. 32 MB) could benefit cache-sensitive applications. However, its 125-watt TDP means it requires a robust cooling solution, typical of desktop systems.

In the absence of direct head-to-head benchmark data, the choice is clear by segment. For a mobile system, the AMD Ryzen 7 8745HX is the only option with recorded performance, and its scores are competitive with desktop parts. For a desktop system requiring ECC memory and high clock speeds, the Intel Core i9-14901KE offers those features, but its performance remains unquantified in this database. The data does not support a direct winner; it supports a split by use case.
