AMD Ryzen 9 5950X vs Intel Core i7-13850HX Comparison

The Verdict

The benchmark data splits these two processors into clearly distinct roles. The AMD Ryzen 9 5950X wins 9 of the 15 head-to-head comparisons, while the Intel Core i7-13850HX takes 6. The AMD part dominates throughput-heavy workloads, particularly data compression (41.4% ahead), integer math (46.2% ahead), and extended instructions (52.2% ahead). The Intel part counters with decisive single-core advantages, including a 62.8% lead in Cinebench R23 single-core and a 38.9% lead in Cinebench R15 single-core. For users whose workloads scale across many threads, the Ryzen 9 5950X is the stronger choice. For applications that depend on high per-core frequency, the Core i7-13850HX is the better fit. The data does not support a single universal winner; it supports a workload-based split.

Architecture Differences

The two processors represent fundamentally different design philosophies and market segments. The AMD Ryzen 9 5950X is a desktop part built on the Zen 3 architecture (codenamed Vermeer) using a 7 nm process from TSMC. It packs 16 cores and 32 threads, with a base clock of 3.40 GHz and a boost clock of 4.90 GHz. The Intel Core i7-13850HX is a mobile processor based on Raptor Lake, manufactured on Intel's 10 nm process. It offers 20 cores and 28 threads, with a lower base clock of 2.10 GHz but a higher boost clock of 5.30 GHz.

Cache hierarchies differ significantly. The AMD chip provides 64 KB of L1 and 512 KB of L2 per core, plus 64 MB of shared L3 cache. The Intel chip offers 80 KB of L1 and 2 MB of L2 per core, but only 30 MB of shared L3. The larger L3 on the AMD part likely contributes to its strong performance in data-heavy workloads. The Intel part compensates with a higher boost clock, which directly benefits single-threaded performance.

Memory support also diverges. The Ryzen 9 5950X supports DDR4 memory with a dual-channel bus and a measured bandwidth of 51.2 GB/s. The Core i7-13850HX supports both DDR4 and DDR5, also on a dual-channel bus, though no bandwidth figure is provided in the data. Both processors support ECC memory. The AMD part uses the AM4 socket and is unlocked for overclocking; the Intel part uses BGA 1964 and is also unlocked. The Intel chip includes integrated UHD Graphics 770, while the AMD chip has no integrated graphics. PCIe capabilities differ as well: the AMD part offers Gen 4 with 20 lanes, while the Intel part offers Gen 5 with 20 lanes.

Transistor counts and die sizes are not directly comparable. The AMD processor contains 8,300 million transistors across a dual-die design of 2x 74 mm². The Intel processor's die size is listed as 257 mm², with no transistor count provided. The AMD part was released on 2020-11-04 with a launch MSRP of $799. The Intel part was released on 2023-01-03 with a launch MSRP of $428.

Where Each One Wins

The AMD Ryzen 9 5950X wins in raw computational throughput. Its 16 cores and 32 threads deliver substantial margins in multi-threaded integer work, floating-point math, and data manipulation. The data shows a 46.2% lead in PassMark integer math and an 8.6% lead in floating-point math. In Cinebench R15 multi-core, the AMD part scores 4324 against 3093 for Intel, a 39.8% advantage. The AMD chip also leads in data compression (41.4%), data encryption (51.9%), extended instructions (52.2%), prime number finding (23.9%), random string sorting (32.5%), and the overall PassMark multi-thread score (23.2%). This pattern points to rendering, scientific computing, and server-like workloads as the AMD part's home turf.

The Intel Core i7-13850HX wins where clock speed and single-core efficiency matter most. Its Cinebench R23 single-core score of 4333 dwarfs the AMD's 1614, a 62.8% gap. The Cinebench R15 single-core result is similar: 436 versus 266.5, a 38.9% lead. The PassMark single-thread score favors Intel by 7.9% (3769 versus 3470). Intel also wins in PassMark physics (2483 versus 1878, a 24.4% advantage) and in Cinebench R23 multi-core (30695 versus 26017, a 15.2% lead). The R23 multi-core win is notable because it contradicts the R15 multi-core result, suggesting the Intel part scales better under the newer, longer-running Cinebench workload.

The overall benchmark averages reflect this split. The AMD Ryzen 9 5950X has an average benchmark score of 51947 and sits at the 91st percentile of all CPUs. The Intel Core i7-13850HX has an average score of 50761 and sits at the 90th percentile. The nearest rivals for the AMD part include the Intel Core Ultra 5 235HX (delta -0.2%), AMD EPYC 8124P (delta -0.3%), Intel Core i9-13900F (delta +0.4%), and Intel Core i7-14700 (delta -0.7%). The Intel part's nearest rivals include the AMD Ryzen 9 5900XT (delta +0.1%), Intel Core i9-14900T (delta -0.5%), AMD Ryzen AI 9 HX PRO 370 (delta +0.6%), and Intel Core i9-13980HX (delta +0.7%). These deltas show both processors competing within a tight performance band around their respective averages.

Head-to-Head Benchmarks

The most striking result in the dataset is the Cinebench R23 single-core comparison. The Intel Core i7-13850HX scores 4333, while the AMD Ryzen 9 5950X manages only 1614. That is a 62.8% deficit for the AMD part. The gap is even more pronounced in percentage terms than the multi-core differences, highlighting how far ahead the Intel architecture is on a per-thread basis. The Cinebench R15 single-core result tells the same story: 436 for Intel versus 266.5 for AMD, a 38.9% lead.

The multi-core picture is more complex. In Cinebench R15 multi-core, the AMD Ryzen 9 5950X wins decisively with 4324 versus 3093, a 39.8% margin. But in Cinebench R23 multi-core, the Intel part flips the result: 30695 versus 26017, a 15.2% lead. This reversal suggests the Intel part sustains its performance better over the longer R23 workload, while the AMD part's advantage in R15 may come from its higher base clock and larger cache.

The PassMark suite heavily favors the AMD Ryzen 9 5950X. The largest single margin is in extended instructions, where AMD leads 40468 versus 26586, a 52.2% gap. Data encryption shows a 51.9% lead (39593 versus 26062). Integer math gives AMD a 46.2% advantage (185520 versus 126852). Data compression is 41.4% ahead (624347 versus 441525). Random string sorting shows a 32.5% lead (65172 versus 49198). Prime number finding is 23.9% ahead (228 versus 184). The overall PassMark multi-thread score favors AMD by 23.2% (45424 versus 36870). Floating-point math is the closest AMD win at 8.6% (100280 versus 92369).

The Intel Core i7-13850HX wins the remaining benchmarks. PassMark physics favors Intel by 24.4% (2483 versus 1878). PassMark single-thread favors Intel by 7.9% (3769 versus 3470). The same single-thread score appears twice in the data (passmark_single_thread and passmark_singlethread), both showing the same 7.9% Intel advantage.

The win count reflects this distribution: AMD takes 9 wins, Intel takes 6. However, the magnitude matters. Intel's wins include the two largest single-core margins in the dataset, while AMD's wins are spread across many workload types. The data suggests that for heavily threaded, data-intensive tasks, the Ryzen 9 5950X is the stronger part. For latency-sensitive, single-threaded tasks, the Core i7-13850HX is clearly superior. The overall averages (51947 for AMD, 50761 for Intel) put them within 2.3% of each other, meaning the choice should be driven by the specific workload mix rather than a general performance rating.
