AMD Ryzen 7 PRO 5845 vs Intel Core i5-14500HX Comparison

The AMD Ryzen 7 PRO 5845 and Intel Core i5-14500HX represent two distinct design philosophies: a desktop-class Zen 3 processor aimed at professional workstations versus a mobile-first Raptor Lake-HX chip with hybrid core architecture. Benchmark data shows a decisive overall victory for the Intel part, which claims 15 of 17 head-to-head tests, but the AMD chip secures meaningful wins in specific workloads that reveal its architectural strengths.

Head-to-Head Benchmarks

The Intel Core i5-14500HX dominates the Cinebench suite with remarkable consistency. Across all six Cinebench tests (R15, R20, and R23, each with single-core and multi-core variants), the Intel processor wins by exactly 8.6% in every instance. The R23 multi-core score of 24,234 versus 22,145 for the AMD Ryzen 7 PRO 5845, and the single-core score of 3,421 versus 3,126, show a uniform 8.6% gap that persists regardless of thread count. This consistency suggests a fundamental per-core performance advantage rather than a scaling effect.

The Passmark suite tells a similar story but with wider variance. The most dramatic Intel victory comes in the floating-point math test, where the i5-14500HX scores 69,442 against the AMD's 52,105 — a 25% advantage. Physics performance is even more lopsided: Intel scores 1,911 versus AMD's 1,109, a 42% difference. Random string sorting shows Intel ahead by 6.8% (36,219 vs 33,754), and prime number finding favors Intel by 11.5% (130 vs 115). Integer math is nearly a tie, with Intel's 95,584 barely edging out AMD's 94,884 by 0.7%. Data compression goes to Intel by 5.8% (333,851 vs 314,363), while the multithread test shows Intel leading 28,508 to 26,054, an 8.6% margin that mirrors the Cinebench results.

The AMD Ryzen 7 PRO 5845 claims only two wins, but they are notable. The extended instructions test sees AMD leading 21,117 to 20,019, a 5.5% advantage. Data encryption also goes AMD's way by 1.6% (19,815 vs 19,502). These wins suggest the Zen 3 architecture handles certain instruction-level operations more efficiently, even when behind in raw throughput.

Looking at aggregate scores, the AMD part's average benchmark score of 35,802 places it at the 85th percentile of all CPUs, while the Intel's 35,094 sits at the 84th percentile. The AMD's nearest rival, the Intel Core 7 250H, scores 35,728 (0.2% behind), and the AMD Ryzen 7 7700X leads it by 0.3%. The Intel i5-14500HX's nearest rival, the Intel Core i9-12900HX, trails by 0.3%, while the Core i7-12700K leads by 0.5%. These percentile positions show both processors landing in the upper tier of CPU performance, despite the Intel's clear head-to-head dominance.

Architecture Differences

The two processors diverge sharply in their core designs. The AMD Ryzen 7 PRO 5845 uses 8 cores and 16 threads based on the Zen 3 architecture, codenamed Vermeer, built on TSMC's 7 nm process with 4,150 million transistors on a 74 mm² die. Each core contains 64 KB of L1 cache and 512 KB of L2 cache, with 32 MB of shared L3 cache. This is a monolithic desktop design on the AMD Socket AM4 platform.

The Intel Core i5-14500HX employs 14 cores and 20 threads using the Raptor Lake architecture, codenamed Raptor Lake-HX, fabricated on Intel's 10 nm process with a much larger 257 mm² die. Each core carries 80 KB of L1 cache and 2 MB of L2 cache, with 24 MB of shared L3 cache. This is a mobile processor on the Intel BGA 1964 socket. The Intel part includes integrated graphics (UHD Graphics 770), while the AMD chip has no integrated graphics listed.

Cache allocation strategies differ substantially. Intel's per-core L2 cache is four times larger at 2 MB versus 512 KB, but AMD's total L3 cache is 32 MB against Intel's 24 MB. The AMD chip is a pure 8-core/16-thread design, while Intel's 14-core/20-thread configuration implies a hybrid arrangement of performance and efficiency cores, though the exact breakdown is not specified in the data.

Process technology and foundry also differ: AMD uses TSMC's 7 nm node, while Intel fabricates on its own 10 nm process. The transistor count and die size differences reflect these architectural choices — AMD packs 4,150 million transistors into 74 mm², while Intel's 257 mm² die has no listed transistor count.

Specification Differences

The AMD Ryzen 7 PRO 5845 and Intel Core i5-14500HX differ across nearly every core specification. Core counts: 8 versus 14. Thread counts: 16 versus 20. Base clock speeds: 3.40 GHz versus 2.60 GHz. Boost clocks: 4.60 GHz versus 4.90 GHz. TDP ratings: 65 W versus 55 W. Sockets are incompatible: AMD Socket AM4 versus Intel BGA 1964.

Memory support diverges significantly. The AMD chip supports only DDR4, while the Intel part supports both DDR4 and DDR5. AMD lists a memory bandwidth of 51.2 GB/s, while Intel does not provide a figure. Both support ECC memory and dual-channel configurations. PCIe specifications differ: AMD offers Gen 4 with 20 CPU lanes, while Intel provides Gen 5 with 16 CPU lanes.

The Intel processor has an unlocked multiplier, whereas the AMD chip is locked. Release dates are nearly two years apart: the AMD launched in April 2022, and the Intel in January 2024. The AMD is a desktop-market part, while the Intel is mobile-market. Intel includes UHD Graphics 770 integrated graphics; AMD includes none. Process nodes: 7 nm for AMD, 10 nm for Intel. The AMD uses a 74 mm² die, Intel a 257 mm² die.

The Verdict

The data points to a clear winner for most workloads: the Intel Core i5-14500HX. It wins 15 of 17 benchmarks, including every Cinebench test by 8.6% and the Passmark multithread test by the same margin. The 25% floating-point math advantage and 42% physics lead are decisive for compute-heavy applications. Users running rendering, simulation, or physics-based workloads should prioritize the Intel part based on these results.

The AMD Ryzen 7 PRO 5845 retains appeal for specific tasks. Its wins in extended instructions (5.5%) and data encryption (1.6%) show strengths in cryptography and specialized instruction sets. The higher base clock of 3.40 GHz versus 2.60 GHz and the larger 32 MB L3 cache may benefit certain workloads, though the benchmark data does not isolate these effects. The AMD part also holds a slightly higher global percentile (85th vs 84th) despite losing the head-to-head.

Platform differences matter. The AMD uses Socket AM4 with DDR4 and PCIe Gen 4, while the Intel uses BGA 1964 with DDR4/DDR5 and PCIe Gen 5. The Intel's integrated UHD Graphics 770 provides a fallback display output, while the AMD requires a discrete GPU. The Intel's unlocked multiplier offers overclocking potential, which the locked AMD chip lacks. The Intel's lower 55 W TDP suggests better power efficiency, though the AMD's 65 W rating is modest for a desktop part.

For buyers who need maximum throughput in general productivity, rendering, and multi-threaded applications, the Intel Core i5-14500HX is the data-backed choice. For those prioritizing encryption performance, extended instruction workloads, or preferring the AMD platform's desktop socket and larger L3 cache, the Ryzen 7 PRO 5845 remains competitive despite its overall deficit. The Intel processor's release two years later also brings newer platform features, though the AMD chip's active production status confirms continued availability.
