AMD Ryzen 5 PRO 8640U vs Intel Core i5-14501E Comparison

AMD Ryzen 5 PRO 8640U and Intel Core i5-14501E are both six-core, twelve-thread processors, but they target different segments. The Ryzen is a mobile part built for thin-and-light laptops, while the Intel chip is a desktop processor. The database contains a full benchmark profile for the AMD chip, while the Intel part currently has no recorded benchmark scores. This limits direct performance comparisons, but the available data still allows for a clear analysis of what each processor brings to its respective platform.

Where Each One Wins

The AMD Ryzen 5 PRO 8640U delivers strong multi-threaded performance for its power envelope. Its recorded Cinebench R23 multi-core score of 19,982 and PassMark multi-thread score of 22,795 indicate it can handle sustained workloads like video encoding, 3D rendering, and software compilation. The single-core results are equally respectable, with a Cinebench R23 single-core score of 2,821 and a PassMark single-thread score of 3,732. These numbers place the chip in the 81st percentile of all CPUs in the database, meaning it outperforms most processors currently tracked.

The Intel Core i5-14501E, by contrast, has no benchmark entries in the database. Its performance profile cannot be quantified from recorded data. What the database does show is its specification sheet, which reveals a higher boost clock of 5.20 GHz compared to the AMD's 4.90 GHz, and a larger 24 MB shared L3 cache versus the AMD's 16 MB. The Intel part also supports both DDR4 and DDR5 memory, giving platform flexibility that the AMD chip lacks, as it only supports DDR5. The Intel chip's 65-watt TDP suggests a desktop-oriented design where power draw is less constrained than in a mobile chassis.

The AMD chip wins in portability and efficiency. Its 28-watt TDP and 4 nm TSMC process node indicate it is built for battery-powered devices. The Intel part, with a 10 nm Intel process and 65-watt TDP, is clearly designed for socketed desktop builds with active cooling. The AMD chip also includes a more capable integrated GPU, the Radeon 760M, which is a notable step up from the Intel UHD Graphics 770 for light gaming and media tasks without a discrete GPU.

The Verdict

Benchmark results favor the AMD Ryzen 5 PRO 8640U in every measured category, but this is only because the Intel Core i5-14501E has no recorded scores. The AMD chip's average benchmark score of 30,254 places it just 0.1% above the AMD Ryzen 7 2700X and 0.4% below the AMD Ryzen 7 7736U and Ryzen 5 7640HS. These rivals are all within a 0.6% band, indicating the Ryzen 5 PRO 8640U is a solid mid-range performer.

The Intel Core i5-14501E should be considered for desktop builders who want an LGA 1700 socket, which offers upgrade paths within Intel's 14th generation lineup. Its higher boost clock and larger cache suggest it could be competitive in lightly-threaded tasks, but the absence of recorded data prevents any confirmation. The AMD chip is the only one of the two with a verified performance record, and it delivers a well-rounded mix of single-core and multi-core capability in a low-power mobile package.

Users choosing between these two should base their decision on platform and form factor. The AMD Ryzen 5 PRO 8640U fits laptops and compact systems with modest cooling. The Intel Core i5-14501E fits desktop motherboards and benefits from a dedicated cooler and more power headroom.

Head-to-Head Benchmarks

The database lists no head-to-head benchmark entries between these two processors. The AMD chip has 17 individual benchmark results, while the Intel chip has none. This is a significant gap in the data. Without Intel scores, no multi-core or single-core comparison can be made directly.

The AMD Ryzen 5 PRO 8640U's best multi-threaded result is its Cinebench R23 multi-core score of 19,982, which is a strong figure for a 28-watt chip. Its PassMark integer math score of 74,875 and floating point math score of 45,265 show balanced arithmetic performance. Data compression scores of 260,925 and encryption scores of 15,843 indicate the chip handles common productivity tasks efficiently. The physics score of 1,154 and prime number finding score of 78 are lower, which suggests the chip is less optimized for certain scientific or simulation workloads.

Single-thread performance is also well documented. The Cinebench R20 single-core score of 1,184 and R15 single-core score of 284 are consistent with the R23 result. PassMark extended instructions score of 19,130 and random string sorting score of 32,114 round out the profile. These numbers give a complete picture of the AMD chip's capabilities, but they cannot be compared against the Intel part's absent data.
