AMD Ryzen Embedded V1756B vs Intel Xeon E3-1245 v5 Comparison

The AMD Ryzen Embedded V1756B and the Intel Xeon E3-1245 v5 are two 4-core, 8-thread processors that deliver nearly identical Cinebench results, yet they are built for entirely different purposes. Benchmark data shows the AMD part wins all six head-to-head comparisons, but by margins so slim—between 0.5% and 1%—that the real differentiators lie in platform features, power envelopes, and lifecycle status. The Xeon counters with ECC memory support and a higher boost clock, while the Ryzen Embedded offers a newer architecture, integrated Radeon graphics, and a lower TDP. For workloads that tolerate non-ECC memory and prioritize efficiency, the AMD chip edges ahead; for mission-critical reliability, the Intel part holds a structural advantage.

Where Each One Wins

The benchmark split is one-sided in raw scores, but the practical wins are more nuanced. The AMD Ryzen Embedded V1756B takes every Cinebench test in the head-to-head data, from R15 single-core (97 vs 96) to R23 multicore (6867 vs 6822). These are sub-1% victories, meaning neither chip will feel faster in everyday use. The real win for AMD is efficiency: it achieves these scores at a 45W TDP, compared to the Xeon’s 80W TDP, making it the better choice for compact, thermally constrained systems where sustained performance per watt matters more than peak throughput.

The Intel Xeon E3-1245 v5 wins where the benchmark data does not apply: memory integrity. Its ECC memory support is a definitive advantage for file servers, database nodes, or any workload where a single-bit error is unacceptable. The Xeon also posts a higher base clock (3.50 GHz vs 3.25 GHz) and boost clock (3.90 GHz vs 3.60 GHz), which could translate to better responsiveness in lightly threaded tasks that are not captured by the Cinebench suite’s single-core tests. However, the data shows these clock advantages do not produce a single benchmark win, and the Xeon’s end-of-life production status makes it a less viable option for new deployments.

Architecture Differences

The two processors come from different architectural lineages. AMD’s V1756B uses the Zen architecture on a 14 nm process from GlobalFoundries, with a 4,950 million transistor count and a 210 mm² die size. Intel’s Xeon E3-1245 v5 uses Skylake-DT on Intel’s own 14 nm process, with 1,750 million transistors and a 122 mm² die. The AMD chip packs more than twice the transistors into a larger die, which supports its integrated Radeon Vega 8 graphics and a more generous cache hierarchy: 128 KB L1 per core and 512 KB L2 per core versus Intel’s 64 KB L1 and 256 KB L2. The Xeon counters with a larger shared L3 cache (8 MB vs 2 MB), which helps in workloads with high data reuse.

Memory support diverges sharply. The Ryzen Embedded supports only DDR4 in dual-channel mode, with no ECC option. The Xeon supports both DDR3 and DDR4 in dual-channel mode, with ECC enabled, and has a specified memory bandwidth of 34.1 GB/s. The Xeon also exposes a PCIe Gen 3 connection with 16 lanes (CPU only), while the AMD part’s PCIe details are not listed in the data. The Xeon’s integrated graphics are HD Graphics P530, whereas AMD uses Radeon Vega 8—both are present, but the AMD solution is generally more capable for light GPU tasks, though no benchmark data confirms this.

The Verdict

Pick the AMD Ryzen Embedded V1756B if your priority is a low-power, actively produced processor with integrated graphics that still matches the Xeon’s performance. The data shows AMD wins all six Cinebench tests, and its 45W TDP makes it suitable for fanless or small-form-factor designs. The 2018 release date means it is the newer part, and its "Active" production status ensures availability for ongoing projects. However, be prepared to accept non-ECC memory and a smaller L3 cache (2 MB vs 8 MB), which could hurt in server-style workloads that rely on large shared caches.

Pick the Intel Xeon E3-1245 v5 if you require ECC memory support and can tolerate an 80W power draw. The Xeon’s 34.1 GB/s memory bandwidth and dual DDR3/DDR4 compatibility give it flexibility in legacy server environments. Its higher clocks (3.50 GHz base, 3.90 GHz boost) provide a theoretical edge in single-threaded tasks, even if the Cinebench R15 and R23 single-core scores show a 1% and 0.6% deficit, respectively. The Xeon’s end-of-life status is a real concern, but for existing sockets (Intel Socket 1151) or retrofits, it remains a capable workhorse. With a launch MSRP of $294, it was positioned as a server-class part, and its ECC support justifies that positioning.

FAQ

Head-to-Head Benchmarks

The AMD Ryzen Embedded V1756B wins every single benchmark in the head-to-head data, but the margins are negligible. In Cinebench R15 multicore, AMD scores 692 against Intel’s 687, a 0.7% lead. The single-core R15 test shows AMD at 97 and Intel at 96, a 1% advantage—the largest delta in the entire set. Moving to Cinebench R20, AMD leads 2884 to 2865 in multicore (0.7%) and 406 to 404 in single-core (0.5%). The R23 results follow the same pattern: 6867 vs 6822 in multicore (0.7%) and 969 vs 963 in single-core (0.6%).

These scores place both chips at the 44th percentile among all CPUs, according to the percentileVsAllCpus field, meaning they are mid-pack performers today. The average benchmark scores are also nearly identical: the AMD part averages 1986, while the Xeon averages 1973. The nearest rivals for the AMD chip include the Intel Core i5-8279U (avg score 1987, 0% delta) and the AMD Ryzen 5 1500X (avg score 1992, -0.3% delta). For the Intel chip, the closest competitors are the Intel Core i7-10810U (avg score 1971, 0.1% delta) and the AMD Ryzen 3 2300X (avg score 1968, 0.2% delta). This suggests both processors are firmly in the same performance tier, and the head-to-head wins are statistical noise rather than meaningful superiority.
