The Verdict

The benchmark data clearly separates these two desktop processors by workload type. The Intel Core i9-14900 is the dominant multi-threaded performer, winning 9 of 11 head-to-head tests, including PassMark multithread by 43.8%, integer math by 59.6%, and floating point math by 63.8%. Its 24 cores and 32 threads deliver a 44,578 PassMark multithread score versus 25,047 for the 6-core, 12-thread AMD part. For users running heavily parallel workloads such as rendering, compilation, or data compression, the Intel chip shows a decisive advantage in the recorded data.

The AMD Ryzen 5 7500X3D wins only two tests, but those wins are instructive. It leads PassMark find prime numbers by 17.6% and PassMark physics by 11.8%. The physics test often reflects cache-sensitive and latency-sensitive behavior, and AMD's 96 MB of shared L3 cache likely explains that result. The single-thread score of 3,494 trails Intel's 4,323 by 19.2%, so even in lightly threaded tasks the Intel part holds the edge in this database.

The choice depends on workload profile. If the priority is maximum multi-threaded throughput and higher single-thread scores, the Intel Core i9-14900 is the better pick across nearly every recorded metric. If the workload is specifically cache-sensitive with moderate thread demand, the AMD Ryzen 5 7500X3D shows a narrow advantage in two tests, but those wins do not offset Intel's broad lead elsewhere. The Intel part also sits at the 92nd percentile versus AMD's 89th, reinforcing its overall standing in the database.

Head-to-Head Benchmarks

The Intel Core i9-14900 dominates the head-to-head comparisons, but the size of its wins varies widely by test type. The largest margin is in PassMark floating point math: Intel scores 120,262 against AMD's 43,594, a 63.8% deficit for AMD. Integer math shows a similar pattern, with Intel at 175,010 versus 70,774, a 59.6% gap. These two tests alone demonstrate the scale of Intel's compute advantage in arithmetic-heavy workloads.

Data compression and encryption also favor Intel substantially. PassMark data compression shows Intel at 550,271 versus AMD's 271,649, a 50.6% difference. Data encryption follows with Intel at 33,540 versus 15,797, a 52.9% gap. Random string sorting gives Intel 61,060 against AMD's 32,999, a 46% lead. Extended instructions show a smaller but still clear margin: Intel at 30,624 versus 20,455, a 33.2% difference.

The multithread test confirms the core-count advantage. Intel posts 44,578, while AMD manages 25,047, a 43.8% delta. Single-thread performance also favors Intel: 4,323 versus 3,494, a 19.2% gap. That single-thread result is notable because it shows Intel's 5.80 GHz boost clock outperforms AMD's 4.50 GHz boost even when only one core is active.

AMD's two wins are concentrated in specific areas. In PassMark find prime numbers, AMD scores 221 against Intel's 188, a 17.6% advantage. In PassMark physics, AMD scores 2,779 versus 2,486, an 11.8% lead. Both are integer-heavy or cache-sensitive tests, and AMD's 96 MB L3 cache likely plays a role. However, these two wins do not change the overall picture: Intel wins 9 of 11 tests, and its average benchmark score of 58,115 exceeds AMD's 44,573 by roughly 30%.

The nearest rivals in the database provide context. AMD's 44,573 average score sits just above the Intel Core i9-13950HX at 44,342 (0.5% delta) and just below the Intel Core i5-14600 at 44,889 (-0.7% delta). Intel's 58,115 average score is almost exactly matched by the Intel Xeon Platinum 8260M at 58,323 (-0.4% delta) and the AMD Ryzen 7 9850X3D at 58,386 (-0.5% delta). This places the i9-14900 in a performance tier that the Ryzen 5 7500X3D does not approach.

Specification Differences

The two processors differ on nearly every core specification. The Intel Core i9-14900 uses 24 cores and 32 threads, while the AMD Ryzen 5 7500X3D uses 6 cores and 12 threads. Base clocks also diverge: AMD runs at 4.00 GHz, Intel at 2.00 GHz. Boost clocks reverse that order, with Intel reaching 5.80 GHz and AMD stopping at 4.50 GHz. Both share a 65 W TDP, which is unusual given the core count gap.

Socket and platform support differ completely. AMD uses Socket AM5, Intel uses Socket 1700. AMD supports DDR5 memory only, while Intel supports both DDR4 and DDR5. Memory bandwidth is recorded for AMD at 83.2 GB/s, while Intel's figure is not recorded in the database. Both use dual-channel memory buses. PCIe lanes differ: AMD offers Gen 5 with 24 lanes (CPU only), Intel offers Gen 5 with 16 lanes (CPU only).

Integrated graphics differ by vendor. AMD includes Radeon Graphics, Intel includes UHD Graphics 770. Both support ECC memory. Neither has an unlocked multiplier, so overclocking through multiplier adjustment is not available for either part. The AMD part number is 100-000001904, the Intel part number is SRN3V. AMD lists a launch MSRP of $269, Intel lists a launch MSRP of $549.

Production status is active for both. Release dates differ: AMD released on 2025-11-11, Intel on 2024-01-07. The AMD part belongs to the 7000 series with the Ryzen 5 generation, while Intel belongs to Core 14th Gen with the Core i9 generation.

Architecture Differences

The architectural split is fundamental. AMD's Ryzen 5 7500X3D uses the Raphael codename with Zen 4 architecture, built on a 5 nm process at TSMC. Intel's Core i9-14900 uses the Raptor Lake-R codename with Raptor Lake architecture, built on a 10 nm process at Intel. AMD's die size is 71 mm², Intel's is 257 mm². AMD lists 11,270 million transistors; Intel's transistor count is not recorded.

Cache hierarchy differs both in size and organization. AMD provides 64 KB of L1 per core, 1 MB of L2 per core, and 96 MB of shared L3. Intel provides 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. The L3 difference is the most striking architectural feature: AMD's 96 MB is more than 2.5 times Intel's 36 MB. This large L3 pool is characteristic of AMD's 3D V-Cache approach, though the database does not list a vCache3d field value for this part.

The core design philosophies also differ. AMD uses 6 full cores with 12 threads, all based on Zen 4. Intel uses 24 cores with 32 threads, which implies a hybrid layout of performance and efficiency cores, though the database does not break down the core types. The high boost clock of 5.80 GHz on Intel suggests a design tuned for single-thread frequency, while AMD's 4.50 GHz boost is lower but paired with a larger cache.

Process technology favors AMD in density and efficiency metrics. The 5 nm TSMC node versus Intel's 10 nm node explains part of the die size difference: AMD fits 11,270 million transistors in 71 mm², while Intel's 257 mm² die carries unrecorded transistor count. The smaller die and lower core count likely contribute to AMD's 65 W TDP matching Intel's 65 W TDP despite far fewer cores.

Memory architecture shows another split. AMD supports only DDR5, Intel supports both DDR4 and DDR5. AMD records 83.2 GB/s of memory bandwidth, while Intel's figure is absent from the database. Both use dual-channel buses. PCIe capacity also differs: AMD provides 24 Gen 5 lanes, Intel provides 16 Gen 5 lanes, both CPU-only.

The benchmark results align with these architectural choices. Intel's higher core count and boost clock drive its wins in multithread, integer, floating point, and single-thread tests. AMD's larger L3 cache appears to drive its wins in find prime numbers and physics, both of which can benefit from keeping more working data on-chip. The architecture differences explain why the two CPUs occupy different performance niches despite identical TDP ratings.
