AMD Ryzen 5 4500U vs Intel Xeon E3-1270 v5 Comparison

The AMD Ryzen 5 4500U and the Intel Xeon E3-1270 v5 are fundamentally different processors, and the benchmark data reflects a clear split between single-core and multi-core workloads. The AMD chip wins three of the four head-to-head comparisons, including a decisive victory in the Cinebench R15 single-core test, while the Intel Xeon takes a significant win in the Cinebench R23 multi-core test. This is not a simple generational victory; it is a case where the newer mobile part dominates in most tests, but the older desktop/server part retains a specific advantage in a modern multi-threaded workload.

Head-to-Head Benchmarks

The most lopsided result in this comparison is the Cinebench R15 single-core test, where the AMD Ryzen 5 4500U scores 174 against the Intel Xeon E3-1270 v5's 100. That is a 42.5% deficit for the Intel part, which is a massive gap for a single-threaded exercise. This result indicates that the Zen 2 architecture in the Ryzen chip delivers dramatically better per-core performance than the aging Skylake design, despite the Xeon's higher base clock of 3.60 GHz versus the Ryzen's 2.30 GHz. The Ryzen's boost clock of 4.00 GHz matches the Xeon's, but the architectural efficiency is clearly superior.

The multi-core results are more nuanced and reveal a split between benchmark versions. In Cinebench R15 multi-core, the AMD Ryzen 5 4500U wins with a score of 892 versus 713 for the Intel Xeon, a 20.1% margin. This is expected given the Ryzen has 6 cores versus 4, but the single-core advantage also carries over to this test. However, the situation reverses entirely in Cinebench R23 multi-core. Here, the Intel Xeon E3-1270 v5 scores 7082, which is 19.6% higher than the Ryzen 5 4500U's 5920. This is a surprising win for the older, lower-core-count processor, and it suggests that the R23 workload scales differently with the Xeon's 8 threads versus the Ryzen's 6 threads. The Xeon's Hyper-Threading capability appears to provide a meaningful boost in this specific test, even though it loses in the older R15 version of the same benchmark.

The final comparison, Cinebench R23 single-core, sees the AMD Ryzen 5 4500U take another win, scoring 1152 against the Intel's 999. That is a 13.3% advantage for the Ryzen, which is less dramatic than the R15 single-core gap but still a clear and consistent pattern. Across the four head-to-head tests, the Ryzen wins three, with the only Intel victory being the R23 multi-core test. The average benchmark scores tell a similar story: the Intel Xeon E3-1270 v5 posts an average of 2048, while the AMD Ryzen 5 4500U posts 2035, a negligible difference. Both processors sit in the 45th to 46th percentile of all CPUs, meaning they are statistically equivalent in overall performance despite their contrasting strengths.

Architecture Differences

The architectural divide between these two parts is stark. The Intel Xeon E3-1270 v5 is built on the Skylake architecture using a 14 nm process node from Intel, while the AMD Ryzen 5 4500U uses the Zen 2 architecture on a 7 nm node from TSMC. This process advantage is significant, as the smaller node allows AMD to pack 9,800 million transistors into a 156 mm² die, whereas Intel fits 1,750 million transistors into a 122 mm² die. The transistor density is far higher on the AMD part, which contributes to its efficiency and per-core performance.

Core and thread configurations differ fundamentally. The Xeon offers 4 cores and 8 threads, relying on Hyper-Threading to double its thread count. The Ryzen 5 4500U offers 6 cores but only 6 threads, meaning it lacks simultaneous multithreading entirely. This is a critical distinction: in multi-threaded workloads that benefit from more threads, the Xeon's 8 threads can compete against the Ryzen's 6 physical cores, as seen in the R23 multi-core result. Cache hierarchies are also different. Both have 64 KB of L1 per core and 8 MB of shared L3, but the L2 cache differs: the Intel has 256 KB per core, while the AMD has 512 KB per core. This doubled L2 cache on the Ryzen likely aids its single-core performance.

Memory support and platform features diverge sharply. The Intel Xeon supports both DDR3 and DDR4 memory with a dual-channel bus and a bandwidth of 34.1 GB/s, while the AMD Ryzen supports DDR4 and LPDDR4 with a dual-channel bus and a higher bandwidth of 51.2 GB/s. The Ryzen's memory bandwidth advantage is substantial. The Xeon supports ECC memory, a critical feature for server and workstation reliability, while the Ryzen does not. PCIe connectivity also differs: the Xeon provides Gen 3 with 16 lanes, while the Ryzen offers Gen 3 with 12 lanes. The Xeon has no integrated graphics, whereas the Ryzen includes Radeon Graphics with 384 SPs, making it a complete APU solution. The Xeon targets the server and workstation market segment and is end-of-life, while the Ryzen is an active mobile part.

Where Each One Wins

The AMD Ryzen 5 4500U wins decisively in single-threaded performance. The Cinebench R15 single-core score of 174 versus 100 is a 42.5% advantage, and the R23 single-core score of 1152 versus 999 is a 13.3% advantage. This makes the Ryzen the clear choice for applications that rely heavily on per-core speed, such as older games, lightly threaded productivity tools, or responsive everyday computing. The Ryzen also wins in Cinebench R15 multi-core, scoring 892 versus 713, a 20.1% margin. This suggests that for older multi-threaded applications that do not scale to many threads, the Ryzen's superior cores win out over the Xeon's extra threads.

The Intel Xeon E3-1270 v5 wins specifically in Cinebench R23 multi-core, scoring 7082 versus 5920, a 19.6% margin. This is the only head-to-head win for the Intel part, but it is a significant one. The R23 benchmark appears to reward the Xeon's 8 threads more than the Ryzen's 6 cores, indicating that for modern, heavily threaded workloads that can utilize more than six threads, the Xeon has an advantage. The Xeon also offers ECC memory support, which is a functional win for users who require error-correcting memory in a workstation or server environment. The Xeon's higher base clock of 3.60 GHz versus 2.30 GHz may also provide a benefit in latency-sensitive tasks that do not boost well, though the benchmark data does not directly show this.

The Verdict

The data presents a clear choice based on workload priority. For users who prioritize single-threaded performance, the AMD Ryzen 5 4500U is the definitive winner. Its 42.5% lead in Cinebench R15 single-core and 13.3% lead in R23 single-core are decisive, and it also wins the older R15 multi-core test by 20.1%. The Ryzen's 6 cores, doubled L2 cache per core, and higher memory bandwidth make it a superior part for most general-purpose and lightly threaded tasks. Its integrated graphics and 15-watt TDP also make it a far more practical and efficient solution for a mobile or compact system.

The Intel Xeon E3-1270 v5 is only the right choice under specific conditions. Its single victory in Cinebench R23 multi-core, with a 19.6% margin, indicates that it handles modern, heavily threaded workloads better than the Ryzen, likely due to its 8 threads. Additionally, the Xeon's support for ECC memory is a critical feature for server and workstation reliability that the Ryzen cannot match. If the workload is a modern multi-threaded application that scales well beyond six cores, and ECC memory is a requirement, the Xeon is the superior pick. Otherwise, the Ryzen 5 4500U's dominance in three of four benchmarks and its overwhelming efficiency advantages make it the better all-around processor. The average scores are nearly identical, but the Ryzen achieves parity with a fraction of the power consumption and a newer architecture.
