AMD Ryzen 5 4600U vs Intel Xeon E5-1630 v3 Comparison

AMD Ryzen 5 4600U and Intel Xeon E5-1630 v3 occupy opposite ends of the computing spectrum: one is a 15-watt mobile processor built for efficiency, the other a 140-watt server/workstation chip designed for sustained throughput. Despite their different market segments and a six-year gap in release dates, both land at the 42nd percentile among all CPUs in the database, with average benchmark scores of 1832 and 1823 respectively. The data shows a clear performance hierarchy in the two shared tests, but the real differentiators lie in architecture, platform features, and the workloads each part was designed to serve.

Where Each One Wins

The AMD Ryzen 5 4600U wins every benchmark in which both processors were tested. In Cinebench R15 multi-core, it scores 1089 against the Xeon’s 635, a 71.5% advantage. The single-core gap is even more pronounced: 175.5 versus 89, a 97.2% lead for AMD. These are not marginal differences; they represent a generational leap in instruction-per-clock efficiency combined with a core-count advantage.

The Intel Xeon E5-1630 v3 does not win any head-to-head test in this comparison. However, its strengths are not captured in the shared benchmark suite. The Xeon supports ECC memory, which the AMD part does not, and it offers quad-channel DDR4 memory with 68.3 GB/s of bandwidth compared to the Ryzen’s dual-channel 51.2 GB/s. For workloads that are memory-bandwidth sensitive or require error-correcting memory for data integrity, the Xeon’s platform provides capabilities the Ryzen cannot match.

In Cinebench R20 and R23, where only the Xeon has scores (2647 and 6303 multi-core; 373 and 889 single-core), the data indicates the Xeon produces respectable absolute numbers for a 2014-era 4-core/8-thread part. But without comparable Ryzen scores, those results cannot be used to establish a win. The Ryzen’s wins are decisive in every measurable shared test, making it the clear performance leader in this matchup.

Architecture Differences

The architectural gulf between these two parts is vast. The Ryzen 5 4600U is built on TSMC’s 7 nm process and packs 9,800 million transistors into a 156 mm² die. It uses AMD’s Zen 2 architecture, codenamed Renoir, with 6 cores and 12 threads. The Xeon E5-1630 v3, by contrast, is a 22 nm Intel Haswell-EP part with 2,600 million transistors on a 356 mm² die, offering 4 cores and 8 threads. The transistor density difference is stark: the AMD chip crams nearly four times as many transistors into less than half the die area.

Clock speeds tell a similar story of different design goals. The Ryzen has a base clock of 2.10 GHz and a boost clock of 4.00 GHz, while the Xeon runs higher at base (3.70 GHz) but barely boosts (3.80 GHz). The Xeon’s high base clock with minimal boost suggests a server-oriented design prioritizing consistent, predictable performance. The Ryzen’s wide boost range reflects a mobile part that can idle low and burst high.

Cache hierarchies differ as well. Both have 64 KB of L1 per core, but the Ryzen has 512 KB of L2 per core versus the Xeon’s 256 KB. In L3, the Xeon has a larger 10 MB shared pool compared to the Ryzen’s 8 MB. The Ryzen compensates with its 7 nm process and Zen 2 architecture, which delivers higher IPC despite less shared cache.

Platform features diverge sharply. The Ryzen is a mobile part on AMD Socket FP6, with integrated Radeon RX Vega 6 graphics and support for DDR4 and LPDDR4 memory. It has no ECC support and uses Gen 3 PCIe. The Xeon is a server/workstation chip on Intel Socket 2011-3 with 40 PCIe Gen 3 lanes (CPU only), quad-channel DDR4, and ECC memory support, but no integrated graphics. The Xeon’s 140 W TDP versus the Ryzen’s 15 W TDP underscores their intended environments: one for battery-powered laptops, the other for always-on workstations.

The Ryzen is listed as Active in production, while the Xeon is End-of-life. The Ryzen launched on 2020-01-05, the Xeon on 2014-09-07. Neither has a launch MSRP on file, and both have locked multipliers.

The Verdict

The benchmark data is unambiguous: the AMD Ryzen 5 4600U is the faster processor in every shared test. It delivers 71.5% higher multi-core performance and 97.2% higher single-core performance in Cinebench R15. For any workload that relies on CPU compute — compilation, rendering, general productivity — the Ryzen is the superior choice based strictly on these results.

The Intel Xeon E5-1630 v3 should only be selected when its platform features matter more than raw performance. Its quad-channel memory architecture with 68.3 GB/s bandwidth and ECC support are meaningful for server applications that need memory capacity, bandwidth, and data integrity. The 40 PCIe Gen 3 lanes also provide expansion potential that the Ryzen’s mobile platform cannot offer.

From a longevity standpoint, the Ryzen is Active while the Xeon is End-of-life. The Ryzen’s 7 nm process and Zen 2 architecture represent a much newer design. The Xeon’s 22 nm node and 2014 release date put it at a distinct disadvantage in both performance and efficiency. Even the Xeon’s higher TDP (140 W versus 15 W) does not translate into a performance win — it simply means the Xeon consumes far more power to produce far less work.

The data supports a simple conclusion: for compute performance, choose the Ryzen 5 4600U. For memory bandwidth and ECC reliability, the Xeon E5-1630 v3 retains niche relevance, but it cannot compete on speed.

Head-to-Head Benchmarks

The two shared benchmarks paint a consistent picture of AMD dominance. In Cinebench R15 multi-core, the Ryzen 5 4600U scores 1089 while the Xeon E5-1630 v3 manages 635. The 71.5% delta is substantial and reflects the combination of two additional cores, four additional threads, and Zen 2’s superior IPC over Haswell. The Ryzen’s 6-core/12-thread configuration simply out-muscles the Xeon’s 4-core/8-thread design in heavily threaded workloads.

The single-core test is even more lopsided. The Ryzen posts 175.5 versus the Xeon’s 89, a 97.2% advantage. This near-doubling of single-thread performance cannot be explained by clock speed alone — the Xeon actually has a higher base clock (3.70 GHz versus 2.10 GHz). The gap is almost entirely attributable to architecture. Zen 2’s IPC advantage over Haswell is immense, and the Ryzen’s 4.00 GHz boost clock helps close the frequency gap when needed.

These results align with the average benchmark scores of both parts. The Ryzen’s average benchmark score is 1832, and the Xeon’s is 1823, a difference of only 0.5%. This near-parity in average score, despite the Ryzen’s massive wins in the shared tests, suggests the Xeon’s additional benchmark results (Cinebench R20 and R23) are helping to keep its average competitive. The Ryzen has fewer benchmark entries in the database, which may skew its average.

Nearest rival data provides context. The Ryzen’s closest rivals include the Intel Core i5-8305G (1831, 0.1% delta) and Intel Xeon E5-2608L v3 (1830, 0.1% delta), indicating it sits in a tight cluster of mid-range performers. The Xeon’s nearest rivals include the Intel Core i7-4790S (1827, -0.2% delta) and Intel Xeon E3-1505M v5 (1817, 0.3% delta), showing it occupies a similar performance tier despite its older architecture.

One notable asymmetry: the Xeon has scores in Cinebench R20 and R23, with multi-core results of 2647 and 6303, and single-core of 373 and 889. These numbers indicate the Xeon scales reasonably in newer benchmarks, but without Ryzen 5 4600U scores in those tests, no direct comparison is possible. The data that does exist consistently favors the AMD part, and the architecture differences — 7 nm versus 22 nm, Zen 2 versus Haswell — strongly suggest the Ryzen would maintain its lead in those newer workloads.
