AMD Ryzen 7 PRO 5875U vs Intel Xeon E-2286M Comparison

The Verdict

The AMD Ryzen 7 PRO 5875U and Intel Xeon E-2286M are both 8-core, 16-thread processors, but they serve very different roles. The Ryzen PRO 5875U is a 15 W mobile part aimed at thin-and-light business laptops, while the Xeon E-2286M is a 45 W server/workstation-class mobile chip. The benchmark data is clear: the AMD Ryzen 7 PRO 5875U wins 7 of the 8 head-to-head tests, including every Cinebench workload, with margins between 9.7% and 9.9%. The Intel Xeon E-2286M only wins in Geekbench multicore, where it is 15.5% ahead. If your work is heavily threaded and uses Geekbench-style workloads, the Xeon E-2286M is the pick. For essentially everything else, the Ryzen PRO 5875U delivers better raw performance per test while running at a third of the TDP. The Xeon E-2286M is end-of-life and was launched at $623, while the Ryzen PRO 5875U remains active in production. For a practical recommendation: choose the Ryzen PRO 5875U for newer, more efficient systems, and only consider the Xeon E-2286M if you specifically need ECC memory support or a workstation-grade platform with more PCIe lanes.

Architecture Differences

The two chips come from different design philosophies. The AMD Ryzen 7 PRO 5875U uses the Zen 3 architecture on a 7 nm TSMC process, with the codename Cezanne-U. It is built for mobile efficiency, with a 15 W TDP and a base clock of 2000 MHz that boosts to 4.50 GHz. The Intel Xeon E-2286M uses the older Coffee Lake architecture on Intel's 14 nm process, with the codename Coffee Lake-H. It is a 45 W part with a base clock of 2400 MHz and a boost of 5.00 GHz. The process node difference is significant: 7 nm versus 14 nm explains much of the efficiency gap. The Ryzen PRO 5875U has a smaller transistor count (10,700 million) but the same die size (180 mm²) as the Xeon, which has no listed transistor count. Both use DDR4 memory in dual-channel configuration, but the AMD chip has a memory bandwidth of 51.2 GB/s versus 42.7 GB/s for Intel. The Xeon E-2286M supports ECC memory, which the Ryzen PRO 5875U does not. Cache layouts differ slightly: both have 64 KB L1 per core and 16 MB shared L3, but the AMD has 512 KB L2 per core while the Intel has 256 KB L2 per core. The integrated graphics differ as well: the AMD uses Radeon Vega 8, while the Intel uses UHD Graphics P630. The Ryzen PRO 5875U has 8 PCIe Gen 3 lanes (CPU only), while the Xeon E-2286M has 16 PCIe Gen 3 lanes. The AMD uses Socket FP6, the Intel uses BGA 1440. The Xeon is marked for the Server/Workstation segment and is end-of-life, while the AMD is an active mobile part. The release dates tell the story: the Xeon launched in May 2019, the Ryzen PRO in April 2022.

Head-to-Head Benchmarks

The head-to-head data shows a consistent pattern across all Cinebench tests. In Cinebench R15 multicore, the Ryzen PRO 5875U scores 1421 against the Xeon's 1295, a 9.7% advantage. In Cinebench R15 singlecore, the AMD leads 200 to 182, a 9.9% margin. The R20 tests repeat the same story: multicore 5922 versus 5396 (9.7% ahead), singlecore 835 versus 761 (9.7% ahead). In Cinebench R23, the AMD scores 14102 multicore and 1990 singlecore, against the Intel's 12848 and 1813, giving the AMD a 9.8% lead in both. The Geekbench results break the pattern. In Geekbench multicore, the Xeon E-2286M wins decisively: 6746 versus 5702, a 15.5% advantage for Intel. That is the only test the Intel wins, and it is a large one. In Geekbench singlecore, the AMD recovers, winning 1594 to 1537, a smaller 3.7% margin. Overall, the AMD wins 7 tests; the Intel wins 1. The average benchmark scores reflect this: the Ryzen PRO 5875U has an average of 3971, placing it in the 57th percentile of all CPUs, while the Xeon E-2286M averages 3822, in the 56th percentile. The AMD's nearest rivals include the Intel Core i7-6900K (delta 0%), the AMD Ryzen 5 PRO 4650G (delta -0.2%), the Intel Xeon E5-2669 v3 (delta 0.3%), and the AMD Ryzen 3 7330U (delta 0.3%). The Xeon's nearest rivals include the AMD Ryzen 9 4900H (delta 0%), the Intel Core i7-8086K (delta 0.6%), the Intel Core i7-9700KF (delta 0.9%), and the Intel Core i7-11700T (delta -1.1%).

Where Each One Wins

The AMD Ryzen 7 PRO 5875U is the clear winner for Cinebench-style rendering and single-threaded workloads. It wins every single-core test across R15, R20, R23, and Geekbench, with margins ranging from 3.7% (Geekbench singlecore) to 9.9% (Cinebench R15 singlecore). It also wins all three Cinebench multicore tests by roughly 9.7-9.8%. This makes it the better choice for mobile users who need strong all-around CPU performance, particularly in content creation tasks that scale with Cinebench scores. Its 15 W TDP means it can fit in thinner laptops with less aggressive cooling, and its active production status means it is a current product. The AMD also has higher memory bandwidth (51.2 GB/s versus 42.7 GB/s) and double the L2 cache per core, which likely contributes to its single-core and Cinebench wins.

The Intel Xeon E-2286M wins only in Geekbench multicore, where it is 15.5% ahead of the AMD. This is a substantial margin and suggests that Geekbench's specific workload mix favors Intel's architecture. The Xeon also brings two practical advantages: ECC memory support and 16 PCIe Gen 3 lanes versus 8. For workstation or server-class mobile systems where data integrity (ECC) or expanded I/O (more PCIe lanes) matters more than raw Cinebench scores, the Xeon E-2286M has a role. It also has a higher boost clock (5.00 GHz versus 4.50 GHz) and a higher base clock (2400 MHz versus 2000 MHz), although this does not translate into wins in the recorded benchmarks. The Xeon is end-of-life and carries a launch MSRP of $623, so it is an older, more expensive part, but its Geekbench multicore strength and platform features define its niche.

For most buyers, the choice is straightforward. If you want a current, efficient mobile processor that wins in Cinebench and single-core tests, take the AMD Ryzen 7 PRO 5875U. If you need ECC memory, more PCIe lanes, and the specific Geekbench multicore performance advantage, the Intel Xeon E-2286M is the only option between the two, despite being older and less efficient. The data does not support using the Xeon for general-purpose work: it loses 7 of 8 benchmarks and has triple the TDP. But for a workstation-class laptop with strict reliability requirements, the Xeon's feature set justifies its existence.
