Architecture Differences

The Intel Core i9-14901E and Intel Core Ultra 7 165UL represent two distinct architectural approaches within Intel's lineup. The i9-14901E is built on Raptor Lake architecture, specifically the Raptor Lake-R refresh, while the Ultra 7 165UL uses Meteor Lake architecture, specifically the Meteor Lake-PS variant. These are fundamentally different designs targeting different workloads.

The i9-14901E uses a 10 nm process node, whereas the Ultra 7 165UL uses a 7 nm process node. This process advantage for the Ultra 7 allows for a more power-efficient design, evidenced by its 15 TDP versus the i9-14901E's 65 TDP. The die size for the i9-14901E is 257 mm², while the die size for the Ultra 7 165UL is not recorded in the database.

Cache hierarchy differs significantly. The i9-14901E has 80 KB of L1 cache per core, while the Ultra 7 165UL has 112 KB per core. Both have 2 MB of L2 cache per core. The major difference is in L3 cache: the i9-14901E has 36 MB shared, compared to 12 MB shared on the Ultra 7 165UL. This 24 MB difference in L3 cache gives the i9-14901E a substantial advantage for workloads that benefit from large working sets.

Memory support also differs. The i9-14901E supports both DDR4 and DDR5 memory, while the Ultra 7 165UL supports DDR5 with capacity depending on the motherboard. Both use dual-channel memory buses, but the Ultra 7 165UL has a recorded memory bandwidth of 89.6 GB/s, while the i9-14901E's memory bandwidth is not recorded in the database. ECC memory is supported on the i9-14901E but not on the Ultra 7 165UL.

PCIe capabilities differ as well. The i9-14901E provides Gen 5 with 16 lanes (CPU only), while the Ultra 7 165UL provides Gen 4 with 8 lanes (CPU only). This gives the i9-14901E both a newer PCIe generation and more lanes, which matters for high-bandwidth expansion cards.

The sockets are different: the i9-14901E uses Intel Socket 1700, while the Ultra 7 165UL uses Intel Socket 1851. This means they are not interchangeable on the same motherboard.

Head-to-Head Benchmarks

The database contains extensive benchmark results for the Intel Core i9-14901E but no recorded benchmark scores for the Intel Core Ultra 7 165UL. The head-to-head benchmark comparison section is therefore limited to analyzing the i9-14901E's performance profile in isolation, with the Ultra 7's capabilities inferred from its specifications.

The i9-14901E's Cinebench scores demonstrate strong multi-core performance. In Cinebench R15, it scores 2595 in multi-core and 366 in single-core. Cinebench R20 shows 10816 multi-core and 1526 single-core. Cinebench R23 delivers 25753 multi-core and 3635 single-core. These results indicate the i9-14901E's high boost clock of 5.60 GHz translates well into single-threaded performance, while its 8 cores and 16 threads handle multi-threaded workloads effectively.

PassMark results for the i9-14901E show exceptional performance in specific workloads. Data compression scores 288777, data encryption scores 18571, and extended instructions score 17249. Integer math scores 112736, floating point math scores 81089, and find prime numbers scores 189. The multi-thread score is 30298, physics scores 3041, and random string sorting scores 39138. Single-thread performance is recorded at 4354.

The i9-14901E's average benchmark score is 37911, placing it at the 86th percentile among all CPUs in the database. The nearest rivals include the AMD Ryzen AI 9 HX 370 with an average score of 37904 (0% delta), the AMD Ryzen 7 9700X with 37943 (-0.1% delta), the Intel Core 5 211E with 37829 (0.2% delta), and the AMD Ryzen AI Embedded P132 with 37804 (0.3% delta). This indicates the i9-14901E sits in a highly competitive performance tier, essentially matching these rivals within a 0.3% margin.

Since the Ultra 7 165UL has no benchmark scores recorded and no nearest rivals listed, direct performance comparisons cannot be made from the database. However, the i9-14901E's 86th percentile ranking versus the Ultra 7's 50th percentile ranking suggests the i9-14901E is positioned significantly higher in overall performance.
