AMD Ryzen 5 PRO 5675U vs Intel Xeon E-2186M Comparison

The AMD Ryzen 5 PRO 5675U and Intel Xeon E-2186M are both 6-core/12-thread processors, but they target different segments: the former is a 15 W mobile part built on TSMC's 7 nm process, while the latter is a 45 W server/workstation chip on Intel's 14 nm node. Benchmark data reveals a split personality: the Ryzen dominates in single-core and most multi-core tests, yet the Xeon posts a significant victory in Cinebench R23 multi-core. The average benchmark scores are close (2988 vs 2912), and their overall percentiles are nearly identical (52nd vs 51st), making the choice dependent on workload specifics rather than overall performance.

Architecture Differences

The two processors are built on fundamentally different architectures and process nodes. The AMD Ryzen 5 PRO 5675U uses the Zen 3 architecture with the Cezanne-U codename, manufactured on TSMC's 7 nm process with a die size of 180 mm² and 10,700 million transistors. In contrast, the Intel Xeon E-2186M uses the Coffee Lake architecture with the Coffee Lake-H codename, manufactured on Intel's 14 nm process with a die size of 154 mm² and no transistor count listed.

Memory and I/O capabilities also differ. The Ryzen supports PCIe Gen 3 with 8 lanes (CPU only), while the Xeon supports PCIe Gen 3 with 16 lanes (CPU only). The Ryzen has a higher memory bandwidth at 51.2 GB/s versus 42.7 GB/s. The Xeon supports ECC memory, a feature absent on the Ryzen. Cache hierarchy differs as well: both have 64 KB of L1 per core, but the Ryzen has 512 KB of L2 per core versus the Xeon's 256 KB, and the Ryzen has 16 MB of shared L3 versus the Xeon's 12 MB.

Integrated graphics are another point of divergence. The AMD chip features Radeon Vega 7, while the Intel chip has UHD Graphics P630. Production status and release dates also contrast: the Ryzen is active and was released in April 2022, while the Xeon is end-of-life and was released in April 2018. The AMD part has a TDP of 15 W and uses AMD Socket FP6, whereas the Intel part has a TDP of 45 W and uses Intel BGA 1440.

The Verdict

The data indicates that the AMD Ryzen 5 PRO 5675U is the overall winner in most benchmarks, taking 5 out of 6 head-to-head tests. It wins Cinebench R15 multi-core with a 38% margin, Cinebench R15 single-core with a 59.6% margin, Cinebench R23 single-core with a 3% margin, Geekbench multi-core with a 3.6% margin, and Geekbench single-core with a 14.2% margin. The Intel Xeon E-2186M only wins Cinebench R23 multi-core, beating the Ryzen by 17.6%.

Given the near-identical average benchmark scores (2988 vs 2912) and percentiles (52 vs 51), the choice should be driven by specific requirements. The Ryzen is preferable for users prioritizing single-core performance, lower power consumption (15 W vs 45 W), and higher memory bandwidth. The Xeon is the pick for scenarios requiring ECC memory support, despite its end-of-life status. The Xeon's 16 PCIe Gen 3 lanes also provide more expansion headroom than the Ryzen's 8 lanes. For most general-purpose workloads, the Ryzen's wins in 5 of 6 tests make it the stronger choice, but the Xeon's Cinebench R23 multi-core lead and ECC support give it a niche.

Head-to-Head Benchmarks

The head-to-head data reveals a clear pattern of AMD dominance in most tests. In Cinebench R15 multi-core, the AMD Ryzen 5 PRO 5675U scores 1326 against the Intel Xeon E-2186M's 961, a 38% advantage. The single-core R15 test is even more lopsided: AMD scores 215.5 versus Intel's 135, representing a 59.6% lead. This suggests the Zen 3 architecture has a significant per-core performance advantage over Coffee Lake in this older rendering benchmark.

In Cinebench R23, the results are counterintuitive. The AMD chip wins single-core with a score of 1387.5 versus the Intel's 1347, a modest 3% margin. However, in multi-core, the Intel Xeon E-2186M reverses the trend, scoring 9542 against AMD's 7866.5, a 17.6% victory for Intel. This is surprising given the AMD chip's higher memory bandwidth and larger caches, but the Xeon's higher boost clock (4.80 GHz) and 45 W TDP may explain the multi-threaded advantage in this specific workload.

Geekbench results favor AMD in both tests. In multi-core, AMD scores 5496 versus Intel's 5306, a 3.6% win. In single-core, AMD scores 1637 versus Intel's 1434, a 14.2% margin. The overall benchmark score averages are close, but the distribution of wins strongly favors the AMD processor. The Ryzen's wins are often by large margins (38%, 59.6%), while its single loss is a 17.6% deficit. This suggests that for most users, the AMD chip offers more consistent performance across a variety of benchmark types.

Where Each One Wins

The AMD Ryzen 5 PRO 5675U is the clear winner in single-core performance across all three benchmark suites (Cinebench R15, Cinebench R23, and Geekbench). It also wins in Geekbench multi-core and Cinebench R15 multi-core. This makes it the better choice for applications that rely heavily on single-threaded performance or lightly-threaded workloads, such as general productivity, web browsing, and many legacy applications. Its lower TDP of 15 W also makes it more suitable for power-constrained mobile devices, and its higher memory bandwidth (51.2 GB/s) benefits memory-intensive tasks.

The Intel Xeon E-2186M's sole benchmark win in Cinebench R23 multi-core (9542 vs 7866.5) indicates it has a niche in heavily multi-threaded rendering workloads that scale well across cores. Its 45 W TDP and higher boost clock of 4.80 GHz likely contribute to this. Additionally, the Xeon's support for ECC memory makes it the only option of the two for server or workstation environments where data integrity through error correction is mandatory. The Xeon also offers 16 PCIe Gen 3 lanes versus the Ryzen's 8, providing more flexibility for expansion cards or NVMe storage. For users needing ECC support or maximum multi-core rendering in Cinebench R23, the Xeon is the data-backed choice, despite being end-of-life and having a higher launch MSRP of $623.
