AMD Ryzen 5 PRO 3500U vs Intel Xeon X5560 Comparison

The AMD Ryzen 5 PRO 3500U and Intel Xeon X5560 are both 4-core, 8-thread processors, but they represent vastly different eras and design goals. The data positions them as near-identical in overall average benchmark score, with the Ryzen at 947 and the Xeon at 946, a mere 0.1% difference. However, this aggregate similarity masks a decisive split in workload performance, driven by a decade of architectural evolution. The Ryzen 5 PRO 3500U is a modern, efficient mobile chip, while the Xeon X5560 is an older, power-hungry server part. The benchmark results show that in the single head-to-head test available, the AMD processor delivers more than double the multi-core performance of the Intel chip, making the choice between them starkly clear for most users.

Head-to-Head Benchmarks

The only directly comparable benchmark between these two CPUs is the Cinebench R15 multi-core test, and the results are not close. The AMD Ryzen 5 PRO 3500U scores 624, while the Intel Xeon X5560 scores 276. This gives the AMD processor a commanding 126.1% advantage. In practical terms, the Ryzen 5 PRO 3500U is more than twice as fast in this rendering workload, a massive gap that speaks to the fundamental differences in their architectures and process technologies.

Beyond this single head-to-head, the data from individual benchmark suites reinforces the AMD processor's dominance in multi-threaded tasks. The Ryzen 5 PRO 3500U posts a Cinebench R15 multi-core score of 624, while the Xeon X5560's score in the same test is 276. The Xeon does have scores in newer Cinebench versions, but the Ryzen lacks those entries, so a direct comparison is not possible. However, the Xeon's Cinebench R20 multi-core score of 1154 and Cinebench R23 multi-core score of 2749 show it is a capable multi-threaded part for its age, but the older R15 comparison clearly favors the AMD chip.

Single-core performance tells a different, though still decisive, story. The Ryzen 5 PRO 3500U achieves a Geekbench single-core score of 819 and a Cinebench R15 single-core score of 142. The Xeon X5560 does not have a Geekbench score in the data, but its Cinebench R20 single-core score of 162 and Cinebench R23 single-core score of 388 suggest it is competitive in per-thread performance. The Ryzen's R15 single-core score of 142 is lower than the Xeon's R20 and R23 scores, but these are different benchmark versions, making a direct comparison invalid. The data does not provide a head-to-head single-core test, so the edge here is less clear-cut than in multi-core.

The overall average benchmark scores are nearly identical, with the Ryzen 5 PRO 3500U at 947 and the Xeon X5560 at 946. This places both processors in the 25th percentile of all CPUs, indicating they are entry-level performers by modern standards. Their nearest rivals include the Intel Pentium Gold G5400T and AMD Phenom II X6 1045T, both scoring around 946. This cluster of similar-scoring CPUs highlights that while the Ryzen is significantly faster in the one test they share, the overall average pulls in other factors that narrow the perceived gap.

The Verdict

The data is unambiguous for users who need raw multi-threaded compute power. The AMD Ryzen 5 PRO 3500U is the clear winner, offering a 126.1% performance advantage over the Intel Xeon X5560 in the Cinebench R15 multi-core test. If rendering, compiling, or any heavily threaded workload is the primary use case, the Ryzen 5 PRO 3500U is the only sensible choice from a performance standpoint. Its 4 cores and 8 threads are matched by the Xeon, but the modern Zen+ architecture extracts far more work from each clock cycle.

For those considering the Xeon X5560, the data offers little encouragement. Its only potential advantage lies in its support for ECC memory, a feature absent on the Ryzen 5 PRO 3500U. This makes the Xeon a niche option for legacy server or workstation applications where data integrity is paramount and the existing platform dictates the choice. However, its 95W TDP versus the Ryzen's 15W TDP makes it a far less efficient part, and its end-of-life production status means it is a legacy component. The Ryzen 5 PRO 3500U, being an active, modern mobile processor, is the better recommendation for virtually any new build or upgrade.

A: The AMD Ryzen 5 PRO 3500U was released in 2019, while the Intel Xeon X5560 was released in 2009. The Ryzen is also an active production part, whereas the Xeon is end-of-life.

Specification Differences

The two processors differ across nearly every major specification, reflecting their distinct generations and target markets. The AMD Ryzen 5 PRO 3500U has a base clock of 2.10 GHz and a boost clock of 3.70 GHz, while the Intel Xeon X5560 has a higher base clock of 2.80 GHz but a lower boost clock of 3.20 GHz. The Ryzen uses the AMD Socket FP5, while the Xeon relies on the older Intel Socket 1366. The Ryzen supports DDR4 memory on a dual-channel bus with 38.4 GB/s of bandwidth, whereas the Xeon supports DDR3 on a triple-channel bus with no bandwidth figure provided. The Ryzen includes integrated Radeon Vega 8 graphics, while the Xeon has no integrated graphics. The Ryzen is a mobile part with a 15W TDP, and the Xeon is a server/workstation part with a 95W TDP. The Ryzen is also an active production part, while the Xeon is end-of-life.

Architecture Differences

Architecturally, these CPUs are generations apart. The AMD Ryzen 5 PRO 3500U is built on the Zen+ architecture, codenamed "Picasso," using a 12nm process at GlobalFoundries. It packs 4,940 million transistors on a 210 mm² die. The Intel Xeon X5560 uses the much older Nehalem architecture, codenamed "Gainestown," on a 45nm process at Intel. It has only 731 million transistors on a larger 263 mm² die. The cache layouts also differ: the Ryzen has 96 KB of L1 cache and 512 KB of L2 cache per core, plus 4 MB of shared L3 cache. The Xeon has 64 KB of L1 and 256 KB of L2 cache per core, but a larger 8 MB of shared L3 cache. The Ryzen supports PCIe Gen 3, while the Xeon is limited to Gen 2. These architectural differences explain the Ryzen's superior performance per watt and its massive lead in the shared multi-core benchmark.

Where Each One Wins

The AMD Ryzen 5 PRO 3500U wins decisively in multi-threaded performance, as shown by its 126.1% lead in the Cinebench R15 multi-core test. This makes it the preferred choice for any workload that leverages all cores, such as video rendering, 3D modeling, or software compilation. Its 15W TDP also makes it the clear winner for mobile or energy-conscious builds, where the Xeon's 95W TDP would be a significant drawback. The Ryzen's modern platform support, including DDR4 memory and PCIe Gen 3, gives it a further edge for system longevity and upgradeability.

The Intel Xeon X5560's only clear win is its support for ECC memory, a critical feature for servers and workstations where memory errors cannot be tolerated. This makes it a viable option for legacy server platforms that require ECC and where the performance deficit is acceptable. Its higher base clock of 2.80 GHz might offer a slight advantage in lightly threaded, latency-sensitive tasks, but the lack of a direct single-core head-to-head benchmark makes this speculative. For all practical purposes, the Ryzen 5 PRO 3500U is the superior processor in the vast majority of real-world scenarios.
