Architecture Differences

The Intel Core i9-14900F is built on Raptor Lake architecture, specifically the Raptor Lake-R refresh, using Intel's 10 nm process. It houses 24 cores and 32 threads, with a base clock of 2.00 GHz and a boost clock of 5.80 GHz. The cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and a shared 36 MB L3 cache. The die size is 257 mm², and the chip supports both DDR4 and DDR5 memory across a dual-channel bus. It is a desktop part on Intel Socket 1700, with PCIe Gen 5 support limited to 16 CPU lanes.

The AMD Ryzen 5 PRO 9645 belongs to the 9000 series (Granite Ridge codename) and is built on Zen 5 architecture using a 4 nm TSMC process. It has 6 cores and 12 threads, with a base clock of 3.90 GHz and a boost clock of 5.40 GHz. Cache includes 80 KB L1 per core, 1 MB L2 per core, and 32 MB shared L3. The transistor count is 8,315 million on a 70.6 mm² die, indicating a denser, more power-efficient design. It supports only DDR5 memory (dual-channel) with a documented 89.6 GB/s bandwidth. The socket is AMD Socket AM5, with PCIe Gen 5 providing 24 CPU lanes.

A key feature difference: the AMD chip integrates Radeon Graphics, while the Intel part has none. Both support ECC memory, but the AMD processor is classified as Server/Workstation market segment, whereas the Intel chip is Desktop. The AMD part also has a more recent release date (2025-09-15) compared to Intel's 2024-01-07. The process node advantage (4 nm vs 10 nm) and smaller die (70.6 mm² vs 257 mm²) suggest AMD's architecture achieves higher density, though the Intel part compensates with substantially more cores and threads.

Head-to-Head Benchmarks

The Intel Core i9-14900F dominates the benchmark suite, winning 8 of 11 head-to-head comparisons. The largest gaps come in compute-heavy workloads. In PassMark integer math, Intel scores 177066 against AMD's 93019, a 90.4% advantage. Floating point math shows a similar 90.6% lead, with Intel at 119550 versus AMD's 62720. These results reflect the core count disparity — 24 cores versus 6 — and indicate that for parallel arithmetic operations, the Intel chip is nearly twice as fast.

Data encryption also favors Intel heavily: 34644 versus 17599, a 96.9% delta. Data compression shows Intel at 564207 versus 363736, a 55.1% lead. Multithread performance is 48% higher on Intel (46532 vs 31434), while physics simulation (2899 vs 1945) shows a 49% advantage. Random string sorting (63728 vs 38410) gives Intel a 65.9% edge. Even in extended instructions, where the gap is smallest, Intel leads by 4.6% (31084 vs 29705).

The AMD Ryzen 5 PRO 9645 wins three benchmarks, all pointing to per-core efficiency. It takes the PassMark single-thread test with 4636 versus 4506, a 2.8% lead. It also wins find prime numbers (235 vs 209), an 11.1% advantage. These wins suggest that AMD's Zen 5 core design has superior single-thread throughput despite lower clocks (5.40 vs 5.80 GHz boost). The prime number test, which often relies on branch prediction and integer latency, shows AMD's architectural strength.

The deltaPct values from the nearestRivals data provide additional context. The Intel chip's average benchmark score is 60008, with rivals like the AMD Ryzen 9 7945HX (60099) and Ryzen 7 8745HX (60104) within 0.2% — effectively a tie. The AMD Ryzen 5 PRO 9645 averages 58916, with its nearest rival, the AMD Ryzen AI 9 HX 470, at 58826 (0.2% behind). Both chips sit at the 92nd percentile of all CPUs, but Intel's raw average score is about 1.9% higher.

The Verdict

The data presents a clear split: the Intel Core i9-14900F is the multi-threaded workhorse, while the AMD Ryzen 5 PRO 9645 excels in single-thread and latency-sensitive tasks. For users running heavily parallel workloads — video rendering, 3D simulation, data compression, encryption — the Intel chip's 48% multithread lead and 90%+ advantages in integer and floating point math make it the obvious choice. Its 24 cores and 32 threads dominate any scenario that can scale across cores.

Conversely, the AMD Ryzen 5 PRO 9645's wins in single-thread (by 2.8%) and prime number finding (by 11.1%) indicate superior per-core performance. This matters for lightly threaded applications, legacy code, or interactive workloads where latency dominates. Its 4 nm process and 89.6 GB/s memory bandwidth also suggest better power efficiency and memory throughput per core, though no power figures are available to confirm.

The market segment distinction is telling: Intel markets the 14900F as a desktop CPU, while AMD positions the 9645 for server/workstation use. This aligns with the benchmark profile — Intel for consumer desktop performance, AMD for professional single-thread responsiveness. Both are locked (no unlocked multiplier), and neither has a listed launch MSRP for the AMD part (Intel is $524). The Intel chip also has a 92nd percentile ranking and a higher average score (60008 vs 58916), but the AMD part matches that percentile with fewer cores.

Where Each One Wins

Intel Core i9-14900F wins in:

• Multi-threaded rendering and batch processing (48% multithread lead)
• Integer and floating-point arithmetic (90%+ leads)
• Data encryption (96.9% lead) and compression (55.1% lead)
• Physics simulation (49% lead) and random string sorting (65.9% lead)
• Any workload that can utilize 24 cores/32 threads versus 6/12

AMD Ryzen 5 PRO 9645 wins in:

• Single-thread responsiveness (2.8% lead in PassMark single-thread)
• Prime number finding (11.1% lead), suggesting better branch handling
• Memory bandwidth per core (89.6 GB/s documented, though Intel lacks a figure)
• Power-efficient density (4 nm process, 70.6 mm² die vs 257 mm²)
• Server/workstation roles with integrated graphics for basic display

The choice hinges on workload type. For a desktop user running modern multi-threaded applications, Intel's core advantage is overwhelming. For a professional or server environment where single-thread latency matters and power density is critical, AMD's Zen 5 design offers a more refined per-core experience despite the core-count deficit. Both sit at the 92nd percentile, but Intel's average score (60008) is closer to its nearest rivals than AMD's (58916), suggesting the 14900F has more headroom in mixed workloads.
