AMD Ryzen Embedded R1606G vs Intel Xeon X3440 Comparison

Head-to-Head Benchmarks

The recorded data presents a split decision between these two processors, with each claiming victory in different workload categories. In the Cinebench R15 multicore test, the AMD Ryzen Embedded R1606G posts a score of 317 against the Intel Xeon X3440's 238, a 24.9% advantage for the AMD part. This is a substantial margin in a legacy rendering workload, suggesting that the newer architecture's efficiency translates into real throughput gains even with fewer physical cores.

However, the picture reverses dramatically in the Cinebench R23 multicore test. Here, the Intel Xeon X3440 scores 2368 compared to the AMD Ryzen Embedded R1606G's 1842, giving Intel a 28.6% lead. This is a curious inversion: the same two processors, both running a multicore rendering benchmark, but across different versions of Cinebench, the winner flips. The R23 result likely reflects the Xeon's 4 cores and 8 threads being more fully utilized as the benchmark scales with modern thread management, whereas the R15 test may not have stressed the Xeon's architecture as effectively.

The single-core results leave no ambiguity. In Cinebench R23 single-core, the AMD Ryzen Embedded R1606G scores 888, obliterating the Intel Xeon X3440's 334. That is a 62.4% deficit for the Intel part, an enormous gap that highlights just how far single-thread performance has advanced between the Nehalem and Zen generations. The Ryzen Embedded's 3.50 GHz boost clock, combined with the architectural efficiency of Zen, delivers nearly two and a half times the single-thread performance of the Xeon.

The head-to-head tally shows 1 win for the Intel Xeon X3440 and 2 wins for the AMD Ryzen Embedded R1606G across the three shared benchmarks. Yet looking at the average benchmark scores, the two are remarkably close: the Xeon averages 815, while the Ryzen Embedded averages 797, a difference of only 2.3%. This near parity in overall average obscures the fact that their strengths are entirely different. The Xeon's average is buoyed by its multicore R23 showing, while the Ryzen Embedded's average benefits from its dominant single-core performance.

Architecture Differences

The fundamental divide between these processors lies in their architectural eras. The Intel Xeon X3440 is built on the Nehalem architecture, specifically the Lynnfield codename, using a 45 nm process node fabricated by Intel. It integrates 774 million transistors on a 296 mm² die. In contrast, the AMD Ryzen Embedded R1606G uses the Zen architecture with the codename "Banded Kestrel," manufactured on a 14 nm process at GlobalFoundries, packing 3,500 million transistors into a much smaller 148 mm² die.

The core configuration tells the story of different design philosophies. The Intel part offers 4 cores and 8 threads, while the AMD part provides only 2 cores and 4 threads. Yet the AMD processor compensates with higher clock speeds: its base clock of 2.60 GHz and boost clock of 3.50 GHz compare favorably to the Xeon's 2.53 GHz base and 2.93 GHz boost. The Ryzen Embedded's boost clock is 19.5% higher than the Xeon's, which directly explains its single-core dominance.

Cache hierarchies differ substantially as well. The Intel Xeon X3440 provides 64 KB of L1 cache per core, 256 KB of L2 per core, and 8 MB of shared L3 cache. The AMD Ryzen Embedded R1606G offers 96 KB of L1 per core, 512 KB of L2 per core, but only 4 MB of shared L3. The AMD part has larger per-core caches, while the Intel part has double the total L3 capacity, a tradeoff that favors the Xeon in data-heavy multicore workloads.

Memory support marks another generational shift. The Xeon uses DDR3 with dual-channel support and a peak bandwidth of 21.3 GB/s, while the Ryzen Embedded uses DDR4 with dual-channel support and 38.4 GB/s of bandwidth. The AMD part's memory bandwidth is 80.3% higher, a significant advantage for memory-bound tasks. The Xeon supports ECC memory, while the Ryzen Embedded does not, which is notable given the Xeon's server/workstation positioning versus the AMD part's mobile segment classification.

The PCI Express capabilities also differ. The Intel Xeon X3440 offers PCIe Gen 2 with 16 lanes, while the AMD Ryzen Embedded R1606G provides PCIe Gen 3 with 8 lanes. The AMD part's newer PCIe standard offers higher per-lane bandwidth, though the Xeon has more total lanes. The Ryzen Embedded includes integrated Radeon Vega 3 graphics, while the Xeon has no integrated graphics, requiring a discrete GPU in all configurations.

The Verdict

The data points toward a straightforward conclusion for different use cases. The Intel Xeon X3440 wins only one of the three head-to-head benchmarks, but that win is substantial: a 28.6% lead in Cinebench R23 multicore. This suggests the Xeon remains competitive in heavily threaded, modern rendering workloads where its 4 cores and 8 threads can be fully engaged. Its 8 MB of shared L3 cache and 16 PCIe Gen 2 lanes also support server-style workloads, and its ECC memory support is a critical feature for reliability-conscious deployments.

The AMD Ryzen Embedded R1606G wins two of the three head-to-head benchmarks, with its single-core advantage being nothing short of dominant. The 62.4% gap in Cinebench R23 single-core means the Ryzen Embedded will feel dramatically snappier in everyday tasks, responsive single-threaded applications, and lightly threaded software. Its 25 W TDP compared to the Xeon's 95 W makes it far more suitable for power-constrained environments, embedded systems, or fanless designs. The integrated Radeon Vega 3 graphics eliminate the need for a separate GPU, simplifying system builds.

Neither processor is a clear overall winner based on the average benchmark scores, which sit at 815 for the Xeon and 797 for the Ryzen Embedded. The percentile rankings are similarly close: 22nd percentile for the Xeon versus 21st for the Ryzen Embedded. The choice comes down to workload priorities.

Where Each One Wins

The Intel Xeon X3440 wins in scenarios that demand multicore rendering performance. Its Cinebench R23 multicore score of 2368 versus the Ryzen Embedded's 1842 makes it the better option for batch rendering, video encoding, or any parallel workload that scales across 8 threads. The Xeon's larger 8 MB L3 cache may also benefit applications with large working sets. Its ECC memory support makes it viable for server or workstation environments where data integrity is paramount, and its 16 PCIe Gen 2 lanes provide more expansion capacity for add-in cards.

The AMD Ryzen Embedded R1606G wins in single-threaded performance, where its 888 Cinebench R23 single-core score is more than double the Xeon's 334. This translates to faster boot times, quicker application launches, and better responsiveness in web browsing, office productivity, and legacy software that rarely uses more than one or two threads. The Cinebench R15 multicore result also favors AMD, with 317 versus 238, suggesting the Ryzen Embedded handles moderately threaded workloads efficiently. The 25 W TDP makes it suitable for passively cooled systems, industrial PCs, or battery-powered devices. The integrated Radeon Vega 3 graphics provide display output without a discrete GPU, and the DDR4 memory support with 38.4 GB/s bandwidth offers higher memory throughput.

For users prioritizing modern single-core performance, energy efficiency, and a compact integrated solution, the AMD Ryzen Embedded R1606G is the data-backed choice. For those needing maximum multicore throughput and server-grade features like ECC memory, the Intel Xeon X3440 retains a meaningful edge despite its age.
