CPU Comparison

The AMD Ryzen 5 4500U and Intel Xeon E-2124G occupy nearly identical positions in the aggregate benchmark landscape, with average scores of 2035 and 2034 respectively, a difference of just 0.1%. Both processors sit at the 45th percentile among all CPUs, indicating that they deliver comparable overall throughput despite radically different design philosophies. The Ryzen 5 4500U is a 6-core, 6-thread mobile part built on TSMC's 7 nm process, while the Xeon E-2124G is a 4-core, 4-thread server/workstation chip on Intel's 14 nm node. Their head-to-head results reveal a split personality: the AMD part dominates in Cinebench R15 and R23 single-core tests, while the Intel part wins the Cinebench R23 multi-core test by a narrow margin. The data shows that the choice between these two hinges entirely on workload type and platform requirements.

Where Each One Wins

The AMD Ryzen 5 4500U claims victory in three of the four direct head-to-head benchmarks, making it the clear winner in single-threaded performance and in the older multi-threaded test. Its most decisive triumph comes in Cinebench R15 single-core, where it scores 174 against the Xeon's 86, a staggering 102.3% advantage. The Ryzen also wins Cinebench R23 single-core with 1152 versus 860, a 34% margin, and Cinebench R15 multi-core with 892 versus 613, a 45.5% lead. These results indicate that for legacy applications, lightly-threaded workloads, and any task that prioritizes per-core speed, the Ryzen 5 4500U is the superior option.

The Intel Xeon E-2124G wins only one head-to-head test: Cinebench R23 multi-core, where it scores 6092 against the Ryzen's 5920, a 2.8% advantage. This narrow victory suggests that in modern, heavily-threaded render workloads, the Xeon's higher base clock of 3.40 GHz and boost clock of 4.50 GHz compensate for its two-core deficit. The Xeon also holds advantages in platform features that the benchmark scores do not capture: it supports ECC memory, offers 16 PCIe Gen 3 lanes (versus 12 on the AMD), and carries a launch MSRP of $218. For server or workstation deployments where data integrity and expansion capability matter more than raw single-thread speed, the Xeon's feature set makes it the practical choice despite losing most benchmarks.

Architecture Differences

The two processors represent fundamentally different architectural generations and design targets. The AMD Ryzen 5 4500U is built on the Zen 2 architecture, codenamed Renoir, using TSMC's 7 nm process node. It packs 9,800 million transistors into a 156 mm² die. The Intel Xeon E-2124G uses the Coffee Lake architecture, specifically the Coffee Lake-S WS variant, on Intel's 14 nm process with a 126 mm² die. The process node difference explains much of the performance-per-watt gap, though the fact pack does not provide direct efficiency metrics.

Core and thread configurations differ substantially. The Ryzen 5 4500U offers 6 cores and 6 threads, meaning it has no simultaneous multithreading. The Xeon E-2124G offers 4 cores and 4 threads, also without hyper-threading. Despite having 50% more cores, the AMD part cannot translate that into a decisive multi-core win across all tests, which highlights the Xeon's higher clock speeds. The Ryzen operates at a 2.30 GHz base clock and 4.00 GHz boost, while the Xeon runs at 3.40 GHz base and 4.50 GHz boost. The Xeon's 0.5 GHz boost advantage is significant for bursty workloads.

Cache hierarchies are similar in total L3 capacity but differ in distribution. Both chips have 8 MB of shared L3 cache. Per-core L2 cache is identical at 512 KB for the Ryzen and 256 KB for the Xeon, giving the AMD part a 2x L2 advantage per core. L1 cache is the same at 64 KB per core for both. Memory support also differs: the Ryzen supports DDR4 and LPDDR4 with a dual-channel bus delivering 51.2 GB/s bandwidth, while the Xeon supports only DDR4 with dual-channel at 42.7 GB/s. The Ryzen's 20% bandwidth advantage could benefit memory-intensive workloads.

Integrated graphics differentiate the two as well. The Ryzen 5 4500U includes Radeon Graphics with 384 shader processors, while the Xeon E-2124G includes HD Graphics P630. The fact pack does not provide graphics benchmark scores, so no performance comparison is possible. The Xeon's ECC memory support is a critical differentiator for error-sensitive workloads, while the Ryzen lacks ECC support entirely. The Ryzen uses the AMD Socket FP6, while the Xeon uses Intel Socket 1151, making them incompatible with each other's platforms.

Head-to-Head Benchmarks

The most dramatic result in the head-to-head comparison is Cinebench R15 single-core, where the Ryzen 5 4500U scores 174 against the Xeon's 86. This 102.3% advantage is more than double, and it is surprising given the Xeon's higher clock speeds. The result suggests that the Zen 2 architecture's instruction-per-clock efficiency vastly outstrips Coffee Lake in this older benchmark version. In Cinebench R23 single-core, the gap narrows to 34%, with the Ryzen scoring 1152 and the Xeon 860. The newer benchmark appears to better utilize the Xeon's higher boost clock, though the Ryzen still leads decisively.

In multi-core tests, the picture is more nuanced. Cinebench R15 multi-core shows the Ryzen winning with 892 versus 613, a 45.5% margin that reflects its 6-core advantage over the Xeon's 4 cores. However, in Cinebench R23 multi-core, the Xeon flips the result, scoring 6092 against the Ryzen's 5920, a 2.8% lead. This reversal is notable: the Xeon's higher base and boost clocks, combined with potentially better scaling in the newer benchmark, overcome the Ryzen's two additional cores. The delta is small, but it demonstrates that the Xeon is not universally slower in multi-threaded work.

The aggregate benchmark scores reinforce the near-parity. The Ryzen 5 4500U has an average benchmark score of 2035, while the Xeon E-2124G sits at 2034. Their nearest rivals include the Intel Core i7-3960X at 2037 and the AMD Opteron 6386 SE at 2038, both within 0.1-0.2% of the two processors. This tight clustering means that neither chip offers a meaningful overall performance advantage; the differences only become apparent when examining specific workload types. The Xeon also has additional benchmark data not available for the Ryzen, including Cinebench R20 scores (2558 multi-core, 361 single-core) and Geekbench scores (4263 multi-core, 1438 single-core), which cannot be directly compared.

The Verdict

The data presents a clear but nuanced recommendation. For users prioritizing single-threaded performance, the AMD Ryzen 5 4500U is the unambiguous choice. It leads by 102.3% in Cinebench R15 single-core and by 34% in Cinebench R23 single-core, making it vastly superior for legacy applications, general desktop responsiveness, and any workload that cannot utilize multiple cores effectively. Its 6-core configuration also gives it a 45.5% advantage in Cinebench R15 multi-core, making it the better all-around performer in most scenarios.

The Intel Xeon E-2124G earns its recommendation in specific professional contexts. Its 2.8% win in Cinebench R23 multi-core shows that modern render workloads can favor its higher clock speeds. More importantly, the Xeon offers ECC memory support, which is essential for data integrity in servers and workstations, and provides 16 PCIe lanes versus the Ryzen's 12. Its launch MSRP of $218 positions it as a server-platform option, though pricing details should not influence the technical assessment. The Xeon is also end-of-life, while the Ryzen remains active in production.

For mobile users, the Ryzen 5 4500U's 15 W TDP makes it suitable for laptops, while the Xeon's 71 W TDP targets desktop server platforms. The Ryzen's 7 nm process and larger transistor count (9,800 million versus no listed count for the Xeon) suggest better efficiency, though the fact pack provides no direct power-performance benchmarks. Ultimately, the Ryzen 5 4500U wins for general-purpose and single-threaded workloads, while the Xeon E-2124G is the pick only when ECC memory, PCIe lane count, or the specific Cinebench R23 multi-core workload are the deciding factors. Given that the Ryzen wins three of four head-to-head tests and ties in aggregate score, it is the more versatile processor for most users.
