AMD Ryzen Embedded R1600 vs Intel Xeon W3550 Comparison

# AMD Ryzen Embedded R1600 vs Intel Xeon W3550

The AMD Ryzen Embedded R1600 and Intel Xeon W3550 are separated by more than a decade of silicon evolution, yet their benchmark results are remarkably close. The Ryzen Embedded R1600 edges out the Xeon W3550 in every single Cinebench test recorded, but the margins are razor-thin—ranging from 0.2% to 0.6% depending on the workload. Both processors sit at the 26th percentile among all CPUs tracked, and their average benchmark scores differ by just 2 points (958 vs 956). The data tells a story of two very different design philosophies converging on nearly identical performance outcomes.

The Verdict

The benchmark data presents an unusual scenario: a 2-core/4-thread embedded processor from 2020 outperforming a 4-core/8-thread workstation Xeon from 2009, but only by the slimmest of margins. The Ryzen Embedded R1600 wins all five head-to-head Cinebench comparisons, yet the largest advantage is a 0.6% lead in Cinebench R20 single-core. In practical terms, these processors are performance equivalents in the tested workloads.

The AMD Ryzen Embedded R1600 is the logical choice for systems where power efficiency and modern platform features matter. Its 25W TDP stands in stark contrast to the Xeon W3550's 130W TDP—a fivefold difference that makes the Ryzen the only sensible option for fanless or thermally constrained embedded designs. The Ryzen also brings DDR4 memory support, PCIe Gen 3, and an active production status, whereas the Xeon is end-of-life with DDR3 and PCIe Gen 2.

The Intel Xeon W3550, despite its age, remains competitive in raw compute because it offers twice the cores and threads. Its 4-core/8-thread configuration compensates for the architectural disadvantages of 45nm Nehalem versus 14nm Zen. However, with production status listed as end-of-life and no modern platform features, the Xeon's appeal is limited to legacy systems or applications where the triple-channel DDR3 memory interface is already in place. For any new design, the data favors the Ryzen Embedded R1600 decisively.

Architecture Differences

The architectural gap between these two processors is substantial. The AMD Ryzen Embedded R1600 uses the Zen architecture on a 14nm process from GlobalFoundries, integrating 3,500 million transistors on a 148 mm² die. The Intel Xeon W3550 uses the Nehalem architecture (codename Bloomfield) on Intel's 45nm process, with 731 million transistors on a 263 mm² die. The comparison is stark: the Ryzen packs nearly five times more transistors into roughly half the die area.

Core configurations differ fundamentally. The Ryzen Embedded R1600 has 2 cores and 4 threads, while the Xeon W3550 has 4 cores and 8 threads. The Ryzen compensates with higher per-core efficiency: its 2.60 GHz base clock and 3.10 GHz boost clock are lower than the Xeon's 3.07 GHz base and 3.33 GHz boost, yet the Ryzen still wins in single-core tests. Cache hierarchies also diverge—the Ryzen has 96 KB L1 and 512 KB L2 per core with 4 MB shared L3, while the Xeon has 64 KB L1 and 256 KB L2 per core with 8 MB shared L3.

Memory support reflects their respective eras. The Ryzen Embedded R1600 uses dual-channel DDR4 with 38.4 GB/s bandwidth, while the Xeon W3550 uses triple-channel DDR3 with no bandwidth figure recorded in the data. Both support ECC memory, which suits their embedded and workstation/server market segments respectively. The Ryzen offers PCIe Gen 3 with 8 CPU lanes; the Xeon provides PCIe Gen 2 without lane count specified.

Power consumption differences are dramatic. The Ryzen's 25W TDP versus the Xeon's 130W TDP represents a 105W gap. This is the single most significant differentiator in the entire comparison, as it determines where each processor can be deployed. The Ryzen's socket is AMD Socket FP5, designed for mobile/embedded applications, while the Xeon uses Intel Socket 1366, a desktop/workstation platform. Neither processor has integrated graphics, and both have locked multipliers.

Head-to-Head Benchmarks

The benchmark results show an extraordinarily consistent pattern: the AMD Ryzen Embedded R1600 wins every test, but by margins that are almost statistically insignificant. In Cinebench R15 multicore, the Ryzen scores 280 against the Xeon's 279, a 0.4% advantage. Cinebench R20 multicore shows 1169 versus 1166, a 0.3% lead. The single-core tests follow the same trend: Cinebench R20 single-core has the Ryzen at 165 versus 164, a 0.6% margin, while Cinebench R23 single-core shows 393 versus 392, a 0.3% difference.

The largest relative win for the Ryzen is in Cinebench R23 multicore, where it scores 2784 against 2778—still just a 0.2% edge. Across all five benchmarks, the Ryzen's average advantage is approximately 0.36%. The head-to-head data records 5 wins for the AMD processor and 0 wins for the Intel Xeon W3550, yet the raw scores are close enough that run-to-run variance could plausibly flip individual results.

What makes these results notable is the core count disparity. The Xeon W3550 brings twice the cores and threads to the table, yet still loses in multicore workloads. This indicates that the Ryzen's Zen architecture delivers substantially higher instructions-per-clock, allowing its 2 cores to match or slightly exceed the Xeon's 4 cores. The Ryzen's 14nm process and modern memory subsystem (DDR4 dual-channel versus DDR3 triple-channel) likely contribute to this efficiency advantage.

The single-core results are particularly telling. Despite the Xeon's higher base clock (3.07 GHz vs 2.60 GHz) and boost clock (3.33 GHz vs 3.10 GHz), the Ryzen still wins by 0.6% and 0.3% in the two single-core tests. This confirms that per-clock performance is significantly better on the Zen architecture. The Xeon's age shows here—Nehalem's out-of-order execution and prefetching are primitive compared to Zen's capabilities.

Where Each One Wins

The AMD Ryzen Embedded R1600 wins in every benchmark category recorded, but its advantages extend far beyond raw compute scores. In power-constrained environments, the 25W TDP versus 130W makes the Ryzen the only viable option for passive cooling, battery-powered devices, or densely packed embedded systems. The Ryzen's modern platform features—DDR4 memory, PCIe Gen 3, and an active production status—make it suitable for new designs requiring longevity and current ecosystem support. Its smaller die size (148 mm² vs 263 mm²) and more advanced 14nm process also indicate lower manufacturing costs per unit, though no pricing data is available to confirm this.

The Intel Xeon W3550's advantages are more situational. Its 4-core/8-thread configuration and 8 MB shared L3 cache may benefit workloads that are heavily multithreaded but not optimized for the Ryzen's particular cache hierarchy. The triple-channel DDR3 memory interface, while older, provides a different memory bandwidth profile that could theoretically benefit certain memory-intensive applications, though no benchmark data confirms this. For legacy systems already built around Socket 1366, the Xeon represents a drop-in upgrade path. Its higher base clock (3.07 GHz) and boost clock (3.33 GHz) could marginally benefit workloads with poor instruction-level parallelism that don't scale with architectural improvements.

The data, however, is unambiguous: in the five Cinebench tests recorded, the Ryzen Embedded R1600 wins all of them. The Xeon's only consolation is that the margins are so small—never exceeding 0.6%—that in real-world usage, users would be hard-pressed to notice any difference in application performance between these two processors. The decision between them ultimately comes down to platform considerations: the Ryzen's modern features and efficiency versus the Xeon's legacy ecosystem and higher core count. For new deployments, the Ryzen's active production status and dramatically lower power draw make it the clear recommendation. For maintaining existing Socket 1366 systems, the Xeon remains a functional, if dated, option.
