AMD Ryzen 7 PRO 4750U vs Intel Xeon E-2186M Comparison

The AMD Ryzen 7 PRO 4750U and Intel Xeon E-2186M represent two different philosophies in mobile computing: one a power-efficient 8-core Zen 2 part, the other a higher-TDP 6-core Coffee Lake workstation chip. Benchmark data reveals a split decision, with the AMD winning in Cinebench R15 and Geekbench multi-core, while the Intel takes newer Cinebench R23 and Geekbench single-core tests. The Ryzen 7 PRO 4750U is the pick for sustained multi-threaded workloads and power-sensitive mobile builds, while the Xeon E-2186M is better suited for single-thread responsiveness and legacy workstation roles. The data shows a 52nd percentile ranking for the AMD versus the 51st for the Intel, making them nearly equal overall, but the nature of their wins dictates different use cases.

The Verdict

The benchmark results indicate a clear split: the AMD Ryzen 7 PRO 4750U wins in older multi-core tests and Geekbench multi-core, while the Intel Xeon E-2186M wins in newer Cinebench R23 tests and single-core performance. For users running legacy software or heavily threaded workloads that scale with core count, the AMD offers up to 46.7% better performance in Cinebench R15 multi-core. Conversely, the Intel Xeon E-2186M is the better choice for single-threaded applications, with a 14.3% lead in Geekbench single-core and a 9.8% edge in Cinebench R23 single-core. The Intel also appeals to workstation users needing ECC memory support, a feature the AMD lacks. The AMD is the more rational pick for a thin-and-light mobile system given its 15W TDP versus the Intel's 45W TDP, while the Intel, now end-of-life, suits legacy workstation deployments where its socket and memory features are already integrated.

Architecture Differences

The architectural gap between these two is substantial. The AMD Ryzen 7 PRO 4750U is built on a 7nm TSMC process with a die size of 156 mm² and 9,800 million transistors, using the Zen 2 architecture codenamed Renoir. It packs 8 cores and 16 threads, with a base clock of 1700 MHz and a boost clock of 4.10 GHz. Its cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and 8 MB of shared L3. The Intel Xeon E-2186M, in contrast, uses a 14nm Intel process with a 154 mm² die, based on the older Coffee Lake architecture. It offers 6 cores and 12 threads, with a higher base clock of 2.90 GHz and boost clock of 4.80 GHz. Its cache design features 64 KB L1 per core, 256 KB L2 per core, and a larger 12 MB shared L3. The AMD supports both DDR4 and LPDDR4 memory with a bandwidth of 51.2 GB/s, while the Intel only supports DDR4 with 42.7 GB/s bandwidth. The AMD lacks ECC support, while the Intel includes it. PCIe lanes differ too: the AMD has 12 Gen 3 lanes, the Intel has 16 Gen 3 lanes. Integrated graphics also differ, with the AMD featuring Radeon RX Vega 7 and the Intel using UHD Graphics P630. The AMD is on the AMDsocket FP6, the Intel on Intel BGA 1440. The Intel has a launch MSRP of $623.

Where Each One Wins

The AMD Ryzen 7 PRO 4750U dominates in multi-threaded legacy benchmarks. Its 1410 score in Cinebench R15 multi-core is a 46.7% improvement over the Intel's 961. In Geekbench multi-core, the AMD scores 5393 versus the Intel's 5306, a slim 1.6% win. These results suggest the AMD's 8-core/16-thread configuration provides better scaling in older rendering workloads. The AMD also holds a 34.1% advantage in Cinebench R15 single-core, scoring 181 versus 135, which is surprising given the Intel's higher boost clock. This indicates the Zen 2 architecture is more efficient per clock in that specific test.

The Intel Xeon E-2186M wins in more modern benchmarks and single-thread tests. Its Cinebench R23 multi-core score of 9542 beats the AMD's 8359 by 12.4%, a significant reversal from the R15 results. In Cinebench R23 single-core, the Intel scores 1347 versus 1215, a 9.8% edge. The Intel's Geekbench single-core score of 1434 beats the AMD's 1229 by 14.3%. These wins suggest the Intel's higher clock speeds (4.80 GHz boost) and larger 12 MB L3 cache give it an advantage in newer, more optimized workloads and single-threaded tasks. The Intel's wins are more relevant for modern software, while the AMD's wins are concentrated in older test suites.

Head-to-Head Benchmarks

The largest single win in the head-to-head data belongs to the AMD in Cinebench R15 multi-core, where it scores 1410 against the Intel's 961. That is a 46.7% delta, a massive gap that underscores the AMD's advantage in older multi-threaded rendering tasks. The AMD's 8 cores and 16 threads clearly outperform the Intel's 6 cores and 12 threads in this test, despite the Intel's higher clock speeds. Similarly, in Cinebench R15 single-core, the AMD wins 181 to 135, a 34.1% margin. This result is more unexpected, given the Intel's 4.80 GHz boost clock versus the AMD's 4.10 GHz, suggesting the Zen 2 architecture's IPC advantage was substantial in this older benchmark.

The Intel fights back decisively in Cinebench R23 multi-core, scoring 9542 versus the AMD's 8359, a 12.4% win. This reversal indicates that the Intel's 12 MB L3 cache and higher clocks matter more in the newer rendering workload, which may be better optimized for Intel's architecture. The Intel also wins Cinebench R23 single-core with 1347 versus 1215, a 9.8% margin. In Geekbench single-core, the Intel extends its lead to 14.3%, scoring 1434 against the AMD's 1229. The only close contest is Geekbench multi-core, where the AMD wins by a slim 1.6% (5393 vs 5306). This near-tie shows that in a modern multi-threaded system benchmark, the two CPUs are almost equivalent, with the AMD's core advantage balancing the Intel's clock advantage.

The data shows a 3-3 split in wins, but the margins tell the story. The AMD's wins in R15 are enormous (46.7% and 34.1%), while its Geekbench multi-core win is marginal (1.6%). The Intel's wins are more moderate: 12.4%, 9.8%, and 14.3%. This pattern suggests the AMD has a more pronounced advantage in legacy multi-threaded workloads, while the Intel has a consistent edge in modern and single-threaded tests. For users prioritizing older software libraries, the AMD is the clear winner; for those on current software, the Intel is the safer bet. The benchmark averages reflect this balance: the AMD's 2965 average is only 1.8% higher than the Intel's 2912, confirming they are closely matched overall.
