AMD Ryzen 5 5600 vs Intel Core Ultra 7 165U Comparison

The AMD Ryzen 5 5600 and Intel Core Ultra 7 165U occupy different corners of the processor market, yet their benchmark averages land nearly on top of each other. The Ryzen 5 5600 posts an average benchmark score of 20,468, while the Core Ultra 7 165U scores 20,249, a gap of roughly 1%. Both sit at the 74th percentile among all CPUs, but the similarity ends there. The Ryzen 5 5600 is a desktop part built for sustained throughput, while the Core Ultra 7 165U is a mobile chip designed for efficiency. The head-to-head data shows a clear split: the AMD part wins 16 of 19 benchmark comparisons, while the Intel part wins 3, with two of those being the same single-thread test.

Where Each One Wins

The Ryzen 5 5600 dominates the multi-core and productivity landscape. In Cinebench R23 multi-core, it scores 18,309 against the Core Ultra 7 165U’s 10,226, a 79% advantage. That gap narrows but remains decisive in Cinebench R20 multi-core, where the AMD part leads 7,689 to 5,943 (29.4% ahead). Geekbench multi-core also favors the Ryzen 5 5600, with a score of 9,158 versus 7,329, a 25% lead. The pattern holds in PassMark’s multithread test, where the AMD chip scores 21,541 against 17,101, a 26% margin.

The Ryzen 5 5600 also wins in integer-heavy and encryption workloads. PassMark integer math shows a 68,396 score for AMD versus 57,785 for Intel, an 18.4% lead. Data encryption goes to AMD at 15,531 versus 11,896, a 30.6% advantage. Data compression is similarly one-sided: 251,687 for the Ryzen 5 5600 versus 188,105 for the Intel part, a 33.8% margin. Even in a prime-number search workload, the AMD chip scores 137 versus 66, a 107.6% advantage, the largest single delta in the comparison.

The Intel Core Ultra 7 165U wins in exactly three areas. PassMark floating-point math goes to Intel at 40,775 versus 38,778, a 4.9% edge. The single-thread PassMark tests, both listed as passmark_single_thread and passmark_singlethread, show Intel ahead at 3,357 versus 3,256, a 3% margin. Those are the only benchmark wins for the mobile chip, and they are narrow. The Intel part’s advantage in floating-point math suggests a different execution pipeline, but it does not translate into broader single-core superiority, as the Ryzen 5 5600 wins Cinebench R23 single-core by 55.5% (2,584 versus 1,662) and Geekbench single-core by 33.5% (1,936 versus 1,450).

Architecture Differences

The two processors come from fundamentally different design philosophies. The Ryzen 5 5600 uses AMD’s Zen 3 architecture, codenamed Vermeer, built on a 7 nm process at TSMC. It packs 6 cores and 12 threads, with a base clock of 3.50 GHz and a boost clock of 4.40 GHz. The chip has a 65 W TDP and fits the AMD Socket AM4. Cache is organized as 64 KB of L1 per core, 512 KB of L2 per core, and 32 MB of shared L3. Memory support is DDR4 on a dual-channel bus, delivering 51.2 GB/s of bandwidth. The processor also supports ECC memory and offers 20 PCIe Gen 4 lanes from the CPU. It has no integrated graphics, and its multiplier is unlocked.

The Intel Core Ultra 7 165U uses the Meteor Lake architecture, built on Intel’s own 7 nm process. It has 12 cores and 14 threads, with a base clock of 1,700.00 MHz and a boost clock of 4.90 GHz. This is a 15 W mobile part, soldered to Intel BGA 2049. Cache amounts to 112 KB of L1 per core, 2 MB of L2 per core, and 12 MB of shared L3. Memory support is DDR5, depending on the motherboard, on a dual-channel bus with 89.6 GB/s of bandwidth. ECC memory is not supported, and the CPU provides 12 PCIe Gen 4 lanes. It includes integrated Arc Xe-LPG 64EU graphics, which the Ryzen 5 5600 lacks entirely. The multiplier is locked, and the part targets the mobile segment.

The core count difference is striking: 12 cores for Intel versus 6 for AMD, yet the AMD part wins nearly every multi-threaded test. That points to the Ryzen 5 5600’s higher per-core performance and the fact that the Intel chip’s 12 cores include efficiency cores that do not scale as well under sustained load. The Intel part’s higher boost clock of 4.90 GHz versus 4.40 GHz does not overcome the architectural advantage of Zen 3. The memory bandwidth figures favor Intel at 89.6 GB/s versus 51.2 GB/s, but that does not translate into benchmark wins. The Ryzen 5 5600 also has a larger L3 cache at 32 MB versus 12 MB, which likely helps in workloads with repeated data access.

The Verdict

Benchmark results indicate that the AMD Ryzen 5 5600 is the stronger processor for almost any compute-heavy task. It wins 16 of 19 head-to-head comparisons, with margins ranging from 12.6% in Cinebench R15 single-core to 107.6% in PassMark’s prime-number search. The AMD part leads in every Cinebench test, every Geekbench test, and most PassMark workloads. For users running multi-threaded applications, rendering, or data processing, the Ryzen 5 5600 is the clear choice from this data.

The Intel Core Ultra 7 165U has a narrow niche. It wins PassMark floating-point math and the two PassMark single-thread tests, but those edges are small (4.9% and 3%, respectively). The mobile chip also includes integrated graphics, which the Ryzen 5 5600 does not have, making it a viable option for a compact system without a discrete GPU. Its 15 W TDP versus 65 W for the AMD part suggests far lower power consumption, though the fact pack does not include measured power figures. For a user prioritizing raw performance over power efficiency, the Ryzen 5 5600 wins outright. For a user needing integrated graphics or a mobile form factor, the Core Ultra 7 165U has a purpose, but the benchmark data does not favor it on raw compute.

Head-to-Head Benchmarks

The Cinebench suite shows the most dramatic separation. In Cinebench R23 multi-core, the Ryzen 5 5600 scores 18,309 against 10,226, a 79% lead. The R20 multi-core test narrows that to 29.4% (7,689 versus 5,943), while R15 multi-core shows a 15% gap (1,845 versus 1,605). Single-core results follow the same direction: Cinebench R23 single-core goes to AMD at 2,584 versus 1,662, a 55.5% margin, and R20 single-core shows a 29.3% lead (1,085 versus 839). The R15 single-core test is the closest of the group, with AMD ahead 260 to 231 (12.6%).

Geekbench results reinforce the AMD advantage. Multi-core scores are 9,158 for the Ryzen 5 5600 versus 7,329 for the Intel part, a 25% lead. Single-core is even more lopsided: 1,936 versus 1,450, a 33.5% margin for AMD. The PassMark suite offers a more mixed picture. The AMD chip wins data compression (251,687 versus 188,105, a 33.8% lead), data encryption (15,531 versus 11,896, a 30.6% lead), extended instructions (16,993 versus 10,610, a 60.2% lead), find prime numbers (137 versus 66, a 107.6% lead), integer math (68,396 versus 57,785, an 18.4% lead), multithread (21,541 versus 17,101, a 26% lead), physics (1,285 versus 1,141, a 12.6% lead), and random string sorting (25,943 versus 21,258, a 22% lead).

The Intel Core Ultra 7 165U takes PassMark floating-point math at 40,775 versus 38,778, a 4.9% edge. It also wins both single-thread PassMark entries with identical scores of 3,357 versus 3,256, a 3% margin. Those three wins are the only spots where the Intel part outperforms, and the deltas are modest compared to the AMD wins. The data shows a processor that is consistently ahead in most compute scenarios, with the Intel chip carving out a narrow niche in floating-point and single-thread PassMark tests. The overall win count of 16 to 3 for AMD reflects a broad performance advantage across rendering, encryption, compression, and general multi-threaded workloads.
