AMD Ryzen Embedded V1807B vs Intel Xeon E3-1275 v5 Comparison

Head-to-Head Benchmarks

The benchmark data shows a clean sweep for the Intel Xeon E3-1275 v5 across all six recorded Cinebench tests, but the margins are consistently narrow. The largest single advantage comes in Cinebench R15 single-core, where the Intel part scores 100 against the AMD Ryzen Embedded V1807B's 98, a 2% lead. Every other test falls within a 1.5% to 1.6% band, making this one of the tighter head-to-head matchups in the database.

In multi-threaded workloads, the Xeon E3-1275 v5 posts a Cinebench R15 score of 712 versus 701 for the Ryzen Embedded part, a 1.6% advantage. The R20 multi-core run shows the same 1.6% delta, with Intel at 2967 and AMD at 2921. The R23 multi-core test repeats the pattern: 7065 for Intel, 6957 for AMD, again a 1.6% gap. Single-core results are similarly close, with the Intel chip leading by 1.5% in both R20 (418 versus 412) and R23 (997 versus 982).

The average benchmark scores in the database tell the same story. The Xeon E3-1275 v5 carries an average score of 2043, placing it just 0.1% behind the AMD Ryzen 5 7520U (2046) and 0.2% behind the Intel Xeon E3-1270 v5 (2048). It sits 0.2% ahead of the Intel Core i7-7700T (2039) and 0.3% ahead of the AMD Opteron 6386 SE (2038). The Ryzen Embedded V1807B averages 2012, landing 0.1% behind the AMD Ryzen 7 1700 (2015) and 0.3% behind both the Intel Core i5-8300H (2005) and the Intel Xeon D-1712TR (2004). The gap between the two contenders in average score is roughly 1.5%, which aligns with the per-test deltas.

Interpreting these numbers, the practical takeaway is that neither chip dominates in raw compute. The Intel Xeon E3-1275 v5 wins every recorded benchmark, but the largest margin is only 2%, and most tests show a 1.5% or 1.6% gap. In real-world terms, that translates to a marginal advantage for Intel in both lightly threaded and fully threaded Cinebench workloads. The consistency of the lead, however, is notable: the Xeon wins equally in single-core and multi-core tests, suggesting a balanced performance profile rather than a workload-specific strength.

Architecture Differences

The two processors come from different architectural lineages, and the database records several fundamental differences. The Intel Xeon E3-1275 v5 is built on the Skylake architecture, specifically the Skylake-DT generation, and uses Intel's 14 nm process with 1,750 million transistors on a 122 mm² die. The AMD Ryzen Embedded V1807B uses the Zen architecture, codenamed Zen (Great Horned Owl), also on a 14 nm node, but manufactured by GlobalFoundries with 4,950 million transistors and a 210 mm² die. The transistor and die size differences are substantial, with AMD packing nearly three times the transistor count into a considerably larger die.

Cache hierarchies differ significantly. The Intel part allocates 64 KB of L1 cache per core and 256 KB of L2 per core, with 8 MB of shared L3 cache. The AMD part doubles the per-core L1 to 128 KB and the L2 to 512 KB per core, but its shared L3 is only 2 MB. This is a striking contrast: Intel offers four times the shared L3 capacity, while AMD compensates with larger per-core L1 and L2 caches. For workloads that repeatedly access a large shared working set, the Intel design likely has an advantage; for per-thread data locality, the AMD design may respond better.

Clock speeds favor Intel on paper. The Xeon E3-1275 v5 has a base clock of 3.60 GHz and a boost clock of 4.00 GHz. The Ryzen Embedded V1807B runs at 3.35 GHz base and 3.80 GHz boost. Both parts have 4 cores and 8 threads, and neither has an unlocked multiplier. The thermal design power differs sharply: the Intel chip is rated at 80 W, while the AMD chip is rated at 45 W. That 45 W figure makes the Ryzen Embedded part substantially more power-efficient per unit of performance, a meaningful consideration for small-form-factor or embedded deployments.

Memory support also diverges. The Xeon E3-1275 v5 supports both DDR3 and DDR4 memory over a dual-channel bus, with a recorded memory bandwidth of 34.1 GB/s. The Ryzen Embedded V1807B supports only DDR4, also dual-channel, but the database does not record a memory bandwidth figure for it. ECC memory is supported on the Intel part, while the AMD part does not record ECC support. The Intel chip uses PCIe Gen 3 with 16 lanes from the CPU, while the database records no PCIe specification for the AMD part.

Integrated graphics differ as well. The Intel Xeon E3-1275 v5 includes HD Graphics P530, while the AMD Ryzen Embedded V1807B includes Radeon RX Vega 11. The database does not record benchmark scores for either integrated GPU, so a direct performance comparison is not possible from this data, but the Vega 11 branding suggests a more capable graphics block for the AMD part.

Production status and market positioning also separate the two. The Intel chip targets the server and workstation segment, is marked end-of-life, and was released in October 2015. The AMD part targets the desktop segment, remains active in production, and was released in February 2018. The launch MSRP of the Intel Xeon E3-1275 v5 is $350; no launch MSRP is recorded for the AMD part. The Intel chip uses the Intel Socket 1151, while the AMD part uses the AMD Socket FP5.

The Verdict

The recorded data points to a straightforward choice for raw single-thread and multi-thread CPU performance: the Intel Xeon E3-1275 v5 wins every Cinebench test in the database, but by margins so slim that they may not be perceptible outside synthetic workloads. The largest gap is 2% in R15 single-core, and the multi-core deltas all sit at 1.5% or 1.6%. For users who need the absolute highest Cinebench numbers, the Intel part is the pick.

However, the AMD Ryzen Embedded V1807B offers a different set of trade-offs that the benchmarks do not capture. Its 45 W TDP versus Intel's 80 W TDP makes it significantly more attractive for thermally constrained or power-sensitive embedded designs. The AMD chip also has a larger L1 and L2 cache per core, which could benefit certain access patterns, and its Radeon RX Vega 11 integrated graphics may outperform Intel's HD Graphics P530, though no benchmark data exists in the database to confirm that.

The Intel Xeon E3-1275 v5 brings ECC memory support, a higher memory bandwidth figure of 34.1 GB/s, broader memory compatibility with both DDR3 and DDR4, and a larger shared L3 cache. It also has a higher base clock and boost clock. But it is end-of-life, carries a recorded launch MSRP of $350, and consumes more power.

The AMD Ryzen Embedded V1807B is still active in production, has a smaller TDP, and comes from a newer release window in February 2018. Its transistor count of 4,950 million and die size of 210 mm² suggest a more complex design, though the database does not record a direct performance benefit from that complexity in the tested Cinebench workloads.

For a server or workstation workload relying on ECC memory and maximum multi-core throughput, the Intel Xeon E3-1275 v5 is the data-backed choice. For an embedded or desktop deployment where power draw matters and the integrated GPU could be a factor, the AMD Ryzen Embedded V1807B presents a compelling alternative despite its slight benchmark deficit. The performance difference between the two is real but small; the deciding factors should come from the non-benchmark specifications, particularly TDP, ECC support, and production status.
