AMD Ryzen 3 PRO 5450U vs Intel Xeon E-2186M Comparison

The Intel Xeon E-2186M and the AMD Ryzen 3 PRO 5450U occupy different corners of the processor market, yet their benchmark scores place them in a surprisingly tight contest. The Xeon, a 45-watt server/workstation part from the Coffee Lake era, and the Ryzen, a 15-watt mobile chip built on Zen 3, end up within 3% of each other in average benchmark score (2912 vs 2829). The data shows a classic trade-off: raw multi-threaded throughput versus modern single-thread efficiency.

Where Each One Wins

The Intel Xeon E-2186M takes the majority of the benchmark victories, winning 7 out of 8 head-to-head tests. Its strongest advantage appears in Geekbench multicore, where it scores 5306 against the Ryzen's 4788, a decisive 10.8% lead. This gap reflects the Xeon's higher core count and thread count, 6 cores and 12 threads versus the Ryzen's 4 cores and 8 threads, which gives it a clear edge in heavily parallel workloads like video rendering, code compilation, and database operations. The Cinebench R23 multicore results tell a similar story, with the Xeon scoring 9542 against the Ryzen's 9403, a 1.5% margin.

The AMD Ryzen 3 PRO 5450U wins only one head-to-head test, but it is a meaningful one: Geekbench single-core. The Ryzen scores 1527 against the Xeon's 1434, a 6.1% advantage. This single-core victory is significant because it indicates that the Ryzen's Zen 3 architecture delivers better per-thread performance despite its lower boost clock of 4.00 GHz versus the Xeon's 4.80 GHz. For everyday tasks that rely on one or two threads, such as web browsing, office productivity, and light coding, the Ryzen is the more responsive chip.

The Cinebench single-core tests are much closer, with the Xeon edging ahead by 1.5% in R15 (135 vs 133), R20 (565 vs 557), and R23 (1347 vs 1327). This suggests that the Xeon's high boost clock can match or slightly exceed the Ryzen's architectural advantage in some single-threaded scenarios, but the Geekbench result shows the Ryzen's ceiling is higher. The use-case split is therefore clear: the Xeon wins sustained multi-threaded work, while the Ryzen wins the most latency-sensitive single-threaded tasks.

Architecture Differences

The two processors come from different generations and design philosophies. The Intel Xeon E-2186M is built on Intel's 14 nm process and uses the Coffee Lake architecture, specifically the Coffee Lake-H variant. It is a 6-core, 12-thread part with a base clock of 2.90 GHz and a boost clock of 4.80 GHz. The die size is 154 mm², and it supports DDR4 memory over a dual-channel bus with a bandwidth of 42.7 GB/s. It includes 12 MB of shared L3 cache, with 64 KB L1 and 256 KB L2 per core. The Xeon also supports ECC memory, a feature absent from the Ryzen, and its integrated graphics are the UHD Graphics P630. The chip is socketed in Intel BGA 1440 and is now end-of-life, having been released in April 2018.

The AMD Ryzen 3 PRO 5450U is a much newer design, built on TSMC's 7 nm process with the Zen 3 architecture, codenamed Cezanne-U. It packs 4 cores and 8 threads into a 15-watt TDP, with a base clock of 2.60 GHz and a boost clock of 4.00 GHz. The die size is larger at 180 mm², and the chip integrates 10,700 million transistors. Cache configuration includes 64 KB L1 per core, 512 KB L2 per core, and 8 MB of shared L3 cache. Memory bandwidth is higher at 51.2 GB/s, also over dual-channel DDR4. The Ryzen has no ECC support and uses the Radeon Vega 6 integrated graphics. It is an active mobile part, released in March 2021, and uses the AMD Socket FP6.

The process node difference is stark: 14 nm versus 7 nm. This explains why the Ryzen achieves competitive performance at a 15-watt TDP while the Xeon requires 45 watts. The Ryzen's smaller transistors allow higher efficiency, which is why it can deliver a higher Geekbench single-core score at a much lower power envelope. The Xeon counters with more cores, a higher boost clock, and ECC support, targeting stability and throughput for workstation-class tasks.

The Verdict

The data points to a straightforward choice based on workload. For users who need maximum multi-threaded throughput in a compact server or workstation form factor, the Intel Xeon E-2186M is the stronger pick. It wins the Geekbench multicore test by a wide 10.8% margin and leads all Cinebench multicore tests, even if by slim 1.5% margins. Its 6 cores and 12 threads, plus ECC memory support, make it suited for tasks that demand reliability and parallel execution, such as rendering, virtualization, or heavy data processing. The 45-watt TDP is higher, but the chip is designed for systems that can handle that thermal load.

For users prioritizing single-thread responsiveness and power efficiency, the AMD Ryzen 3 PRO 5450U is the better option. Its 6.1% Geekbench single-core victory over the Xeon demonstrates superior per-thread performance, which translates to snappier application launches and smoother everyday operation. The 15-watt TDP makes it ideal for thin-and-light laptops or fanless industrial systems where heat and battery life matter more than raw core count. The lack of ECC support is a limitation, but for mainstream mobile workloads, this is rarely a concern.

The overall benchmark averages are nearly identical: the Xeon sits at 2912, the Ryzen at 2829, a difference of about 3%. Both chips fall at the 51st percentile among all CPUs, meaning they are median performers in the broader market. The Xeon's nearest rivals include the AMD Ryzen 5 PRO 1600 (0.1% behind) and the Intel Core i5-1335UE (0.2% behind), while the Ryzen's closest competitors are the Intel Xeon E-2324G (0.2% behind) and the Intel Core i5-10600 (0.3% ahead). Neither chip is a class leader, but each serves its intended segment well.

Head-to-Head Benchmarks

The Geekbench multicore test delivers the largest performance gap in this comparison. The Intel Xeon E-2186M posts 5306 against the AMD Ryzen 3 PRO 5450U's 4788, a commanding 10.8% lead. This is the biggest delta in any test and underscores the value of the Xeon's two extra cores and four extra threads. In a rendering or encoding scenario, that margin would translate to noticeably shorter completion times.

The Geekbench single-core test flips the result. The Ryzen scores 1527, beating the Xeon's 1434 by 6.1%. This is the only test the AMD chip wins, but it is a clear architectural statement. The Zen 3 core is more efficient per clock, and the Ryzen achieves this despite a boost clock that is 0.80 GHz lower than the Xeon's. For users who care about application responsiveness, this is the metric that matters most.

All four Cinebench tests tell a consistent story of narrow Intel wins. In Cinebench R15 multicore, the Xeon scores 961 against 947, a 1.5% margin. The R20 multicore test shows 4007 versus 3949, also 1.5%. The R23 multicore results are 9542 versus 9403, again a 1.5% edge. The single-core variants are similarly tight: R15 single-core is 135 against 133 (1.5%), R20 single-core is 565 against 557 (1.4%), and R23 single-core is 1347 against 1327 (1.5%). These margins are small enough that they could be affected by thermal conditions or power management, but the consistency across all three Cinebench versions suggests the Xeon holds a genuine, if modest, advantage in this benchmark suite.

The average benchmark score for the Xeon is 2912, with its nearest rival being the AMD Ryzen 5 PRO 1600 at 2909 (0.1% difference). The Ryzen 3 PRO 5450U averages 2829, with the Intel Xeon E-2324G at 2823 as its closest competitor. Both processors land at the 51st percentile of all CPUs, meaning they sit right in the middle of the performance distribution. The recorded data shows a near-tie overall, but with very different profiles: the Xeon leans toward throughput, the Ryzen toward efficiency and single-thread speed.
