AMD Ryzen Embedded V1605B vs Intel Xeon D-1527 Comparison

The Intel Xeon D-1527 and AMD Ryzen Embedded V1605B are both 4-core, 8-thread processors aimed at compact, power-conscious systems, but they target different corners of the embedded and server markets. The data shows a clear split: the AMD chip dominates single-threaded and older multi-threaded workloads, while the Intel part pulls ahead in the latest multi-core rendering test. Their average benchmark scores are nearly identical—1207 for the Xeon against 1196 for the Ryzen—yet their performance profiles could not be more distinct.

Where Each One Wins

The AMD Ryzen Embedded V1605B is the clear winner for single-threaded performance and for workloads that rely on older Cinebench versions. In Cinebench R15 single-core, the AMD part scores 128 versus the Intel’s 59, a margin of more than double. That same pattern holds in Cinebench R23 single-core, where the Ryzen posts 841 against the Xeon’s 589. For tasks like light scripting, UI responsiveness, or any application that is not fully multi-threaded, the AMD chip offers a decisive advantage. It also wins in Cinebench R15 multi-core, scoring 654 versus 420, suggesting that older software that scales across cores still favors the higher clock speed of the Ryzen.

The Intel Xeon D-1527, meanwhile, takes the crown in the most demanding multi-threaded test available in this data set: Cinebench R23 multi-core. Here the Xeon scores 4176, which is 32.2% higher than the Ryzen’s 3160. This indicates that under sustained, modern multi-threaded loads, the Xeon’s architecture and memory subsystem pull ahead despite its lower clock speeds. The Xeon is also the only one of the two with ECC memory support, making it the more suitable choice for server or workstation reliability scenarios where data integrity is non-negotiable. Its market segment is listed as Server/Workstation, while the Ryzen is classified as Desktop, reinforcing that split in intended use.

FAQ

Q: Which processor has the higher boost clock?

A: The AMD Ryzen Embedded V1605B boosts to 3.60 GHz, while the Intel Xeon D-1527 tops out at 2.70 GHz. This explains the AMD’s strong single-threaded scores.

Q: Do both processors support ECC memory?

A: No. The Intel Xeon D-1527 supports ECC memory, whereas the AMD Ryzen Embedded V1605B does not. This makes the Xeon the safer pick for error-sensitive workloads.

Q: Which chip wins in Cinebench R23 multi-core?

A: The Intel Xeon D-1527 wins decisively, scoring 4176 against the AMD’s 3160. That is a 32.2% advantage for the Intel part.

Q: How do their average benchmark scores compare?

A: They are nearly identical. The Xeon has an average benchmark score of 1207, and the Ryzen sits at 1196, a difference of just 11 points. Both rank in the 34th percentile of all CPUs.

Q: What is the TDP difference between the two?

A: The AMD Ryzen Embedded V1605B has a TDP of 15 watts, while the Intel Xeon D-1527 is rated at 35 watts. The AMD chip is significantly more energy-efficient on paper.

Q: Which processor has integrated graphics?

A: Only the AMD Ryzen Embedded V1605B includes integrated graphics, featuring Radeon Vega 8. The Intel Xeon D-1527 has no integrated graphics listed.

Head-to-Head Benchmarks

The head-to-head data reveals a lopsided set of wins, with the AMD Ryzen Embedded V1605B taking three of four tests, but the Intel Xeon D-1527 claiming the most important modern workload. In Cinebench R15 multi-core, the AMD chip scores 654 against the Intel’s 420, a delta of -35.8% from the Xeon’s perspective. That is a massive gap in favor of the Ryzen, driven by its higher boost clock and more efficient Zen core design. The single-core R15 result is even starker: the AMD posts 128 versus 59, a 53.9% deficit for the Xeon. Those numbers suggest that for any legacy software or lightly threaded tasks, the Ryzen is the obvious choice.

The script flips in Cinebench R23 multi-core. The Intel Xeon D-1527 scores 4176, while the AMD Ryzen Embedded V1605B manages 3160. The delta is 32.2% in favor of Intel, indicating that the Xeon’s older Broadwell architecture scales better under sustained, modern multi-threading. Notably, the Xeon also has a higher multi-core score in R23 than the Ryzen has in any test, highlighting its strength in prolonged rendering or compilation workloads. In R23 single-core, however, the AMD again wins, scoring 841 versus 589, a 30% advantage. This pattern—AMD winning single-thread and older multi-thread, Intel winning the newest multi-thread—suggests that software optimization matters more than raw clock speed as core counts and instruction sets evolve.

Specification Differences

The two processors differ on nearly every core specification except for core count and thread count, where both have 4 cores and 8 threads. The base clock is a key divergence: the Intel Xeon D-1527 runs at 2.20 GHz, while the AMD Ryzen Embedded V1605B has a base clock of 2.00 GHz—but the boost clock is where AMD leaps ahead, with 3.60 GHz versus Intel’s 2.70 GHz. TDP is another major split, with the Ryzen rated at 15 watts and the Xeon at 35 watts. The AMD chip is built for lower-power embedded systems, while the Intel part draws more than twice the power budget.

Memory support also differs. The Xeon supports both DDR3 and DDR4 memory, while the Ryzen only supports DDR4. Both use a dual-channel memory bus, but the Xeon adds ECC memory support, which the Ryzen lacks. The socket is different as well: the Intel part uses BGA 1667, while the AMD part uses Socket FP5. The Xeon offers PCIe Gen 3 with 24 lanes from the CPU, whereas the Ryzen’s PCIe configuration is not listed in the data. Integrated graphics are exclusive to the AMD chip, which features Radeon Vega 8, while the Intel Xeon has none. The Xeon’s launch MSRP was $213, though no equivalent price is available for the Ryzen.

Architecture Differences

The architectural divide is fundamental. The Intel Xeon D-1527 is built on the Broadwell architecture, specifically the Broadwell-DE generation, using a 14 nm process node fabricated by Intel. The AMD Ryzen Embedded V1605B uses the Zen architecture, also on a 14 nm node, but fabricated by GlobalFoundries. Both are 14 nm parts, yet their transistor counts and die sizes tell different stories. The AMD chip packs 4,950 million transistors on a 210 mm² die, while the Intel part has 3,200 million transistors on a larger 246 mm² die. That higher transistor density likely contributes to the Ryzen’s superior single-thread performance.

Cache hierarchies also diverge significantly. The Intel Xeon D-1527 has 64 KB of L1 cache per core, 256 KB of L2 per core, and 1.5 MB of L3 per core. The AMD Ryzen Embedded V1605B has 128 KB of L1 per core, 512 KB of L2 per core, and a shared 2 MB L3 cache. The AMD’s larger per-core L1 and L2 caches are consistent with its higher single-core scores, while the Intel’s per-core L3 allocation may help in sustained multi-threaded workloads. The Xeon’s generation is listed as Xeon D (Broadwell-DE), released in late October 2015, while the Ryzen is part of the Ryzen Embedded (Zen, Great Horned Owl) generation, released in February 2018. The newer AMD design benefits from more advanced architecture despite the same process node.

The market segments reinforce the intended uses: the Xeon is a Server/Workstation part, while the Ryzen is classified as Desktop. Neither has an unlocked multiplier, and both are marked as Active in production. The Intel part’s part number is SR2DK, while the AMD part’s part number is not listed. The Ryzen’s integrated Radeon Vega 8 graphics is a major architectural feature that the Xeon lacks entirely, making the AMD chip a self-contained system-on-chip for compact designs, whereas the Xeon requires a discrete GPU or a board with integrated video output.
