Intel Core i9-14900 vs Intel Core i9-14901E Comparison

Intel Core i9-14900 and Intel Core i9-14901E share the same Raptor Lake-R architecture, process node, socket, and cache layout, but they are configured very differently. The 14900 is a 24-core, 32-thread processor with a 2.00 GHz base clock and a 5.80 GHz boost clock. The 14901E is an 8-core, 16-thread processor with a 2.80 GHz base clock and a 5.60 GHz boost clock. Both use Intel Socket 1700, have a 65 W TDP, and integrate UHD Graphics 770. The database records 11 benchmark wins for the 14900 and 6 wins for the 14901E, with the 14900 holding a 92nd percentile versus the 14901E’s 86th percentile among all CPUs. The average benchmark score is 58115 for the 14900 and 37911 for the 14901E.

Where Each One Wins

The Intel Core i9-14900 dominates in heavily threaded workloads. Its 24 cores and 32 threads provide a massive parallel advantage, which is reflected in the Cinebench multi-core tests and PassMark’s multi-threaded operations. The 14900 wins Cinebench R15 multi-core by 84.7%, R20 multi-core by 47.1%, and R23 multi-core by 20.6%. It also leads in PassMark data compression by 90.6%, data encryption by 80.6%, extended instructions by 77.5%, floating point math by 48.3%, integer math by 55.2%, multithread by 47.1%, and random string sorting by 56%. This pattern shows the 14900 is the clear choice for rendering, scientific computation, encryption, and any workload that scales with core count.

The Intel Core i9-14901E wins in single-core and lightly threaded scenarios. It takes Cinebench R15 single-core by 13.9%, Cinebench R23 single-core by 39.1%, PassMark physics by 18.3%, and PassMark single-thread by 0.7%. It also edges out the 14900 in PassMark find prime numbers by 0.5%. The 14901E’s higher base clock of 2.80 GHz versus 2.00 GHz helps in tasks that rely on per-core performance, such as physics simulations and certain legacy single-threaded applications. However, the 14901E loses Cinebench R20 single-core by 47.1%, which indicates that not every single-threaded test favors the higher base clock part.

Architecture Differences

Both processors are built on Intel’s 10 nm process and use the Raptor Lake-R codename. They share the same 257 mm² die size and the same cache hierarchy: 80 KB L1 per core, 2 MB L2 per core, and 36 MB shared L3. The socket is identical, Intel Socket 1700, and both support DDR4 and DDR5 memory in dual-channel configuration. They also both support ECC memory, which makes them suitable for workstation and server environments. The PCIe configuration is the same: Gen 5 with 16 lanes from the CPU.

The fundamental difference lies in core count and clock speeds. The 14900 has 24 cores and 32 threads, while the 14901E has 8 cores and 16 threads. This is a 3x difference in core count and a 2x difference in thread count. The 14900’s base clock is 2.00 GHz, but its boost clock reaches 5.80 GHz. The 14901E starts at 2.80 GHz and boosts to 5.60 GHz. The 14901E’s higher base clock gives it an advantage in lightly threaded tasks that do not require boosting, while the 14900’s higher boost clock and many more cores give it the edge in multi-threaded tasks. The integrated graphics are identical, UHD Graphics 770, and both are production-active desktop parts. Neither has an unlocked multiplier.

Head-to-Head Benchmarks

The largest win for the Intel Core i9-14901E is in Cinebench R23 single-core, where it scores 3635 versus 2212, a 39.1% advantage. This is a substantial single-core lead. Cinebench R15 single-core shows a 13.9% advantage for the 14901E, with 366 versus 315. PassMark physics shows an 18.3% advantage, with 3041 versus 2486. PassMark single-thread shows a 0.7% advantage, with 4354 versus 4323. Find prime numbers shows a 0.5% advantage, with 189 versus 188. Notably, Cinebench R20 single-core is an outlier: the 14900 wins by 47.1%, scoring 2245 versus 1526. This inconsistency suggests that the two chips have very different boost behaviors depending on the workload.
