Intel Core i5-5200U vs Intel Xeon X5492 Comparison

Where Each One Wins

The benchmark data presents a clear and one-sided picture in terms of raw compute performance. The Intel Xeon X5492 wins every single head-to-head benchmark recorded in the database, claiming all five victories across the Cinebench suite. The Intel Core i5-5200U does not secure a win in any tested workload. This is not a close contest in any individual metric; the Xeon's advantage is consistent, ranging from 15.9% to 16.5% depending on the specific test.

However, the use-case split is not simply about who wins, but about what each processor is designed to do. The Xeon X5492, a server and workstation part from the Core 2 generation, is built for sustained multi-threaded throughput in professional environments. Its 4 cores and 4 threads at a 3.40 GHz base clock, combined with a 150 W thermal design power, indicate a part that prioritizes absolute compute over efficiency. The Core i5-5200U, conversely, is a mobile processor from the Broadwell generation, with 2 cores and 4 threads, a 2.20 GHz base clock and 2.70 GHz boost clock, and a 15 W TDP. Its purpose is to provide adequate performance within a very tight power envelope for thin-and-light laptops.

The data reflects this division of purpose. In the Cinebench R20 multi-core test, the Xeon scores 1039 against the Core i5's 892, a 16.5% advantage. In single-core performance, the gap is nearly identical, with the Xeon at 146 and the Core i5 at 126 in Cinebench R20, a 15.9% lead. The Xeon's wins are consistent, but the Core i5's losses are all within a similar margin, suggesting that the architectural efficiency of the newer Broadwell design partially compensates for its lower core count and clock speed, though not enough to overcome the Xeon's raw power.

Architecture Differences

The architectural divide between these two processors is substantial, representing nearly two generations of Intel design philosophy. The Xeon X5492, codenamed Harpertown, is built on the Core 2 architecture using a 45 nm process node. It features a dual-die design with a die size of 2x 107 mm² and packs 820 million transistors. Its cache hierarchy is split: 64 KB of L1 per core and 6 MB of L2 per die, with no L3 cache present. It supports DDR2 and DDR3 memory in a dual-channel configuration and includes ECC memory support, a hallmark of server-grade parts. The Xeon uses the Intel Socket 771 interface and has PCIe Gen 2 connectivity. Its market segment is explicitly Server/Workstation, and it was released in 2008.

The Core i5-5200U, codenamed Broadwell-U, is a much newer design, released in 2015. It is fabricated on a 14 nm process, a significant shrink from the Xeon's 45 nm node, and integrates 1,300 million transistors on a single 82 mm² die. Its cache layout is different: 64 KB of L1 per core, 256 KB of L2 per core, and a shared 3 MB L3 cache. This is a more modern hierarchy designed to reduce latency. It supports only DDR3 memory in a dual-channel configuration, with a recorded memory bandwidth of 25.6 GB/s, and does not support ECC memory. The Core i5 uses the Intel BGA 1168 socket, has PCIe Gen 2 with 12 lanes (CPU only), and includes integrated Intel HD 5500 graphics, a feature entirely absent from the Xeon.

These architectural differences explain the performance dynamics. The Xeon's higher base clock of 3.40 GHz versus the Core i5's 2.20 GHz (boosted to 2.70 GHz) gives it a raw speed advantage. The Core i5 compensates with a smaller process node, which improves power efficiency and allows for a much lower TDP of 15 W versus the Xeon's 150 W. The Xeon's lack of L3 cache and reliance on larger L2 slices per die is a legacy design; the Core i5's shared L3 is more efficient for modern workloads. The presence of ECC support on the Xeon and its server socket are clear indicators of its intended role in reliable, always-on systems, while the Core i5's integrated graphics and mobile socket target portable consumer devices.

Head-to-Head Benchmarks

The recorded head-to-head data shows a uniform pattern: the Xeon X5492 leads in every Cinebench iteration. Starting with Cinebench R15 multi-core, the Xeon scores 249 against the Core i5-5200U's 214, yielding a 16.4% lead. This is the smallest relative margin in the multi-core tests, but it is still decisive.

In Cinebench R20, the multi-core gap widens slightly. The Xeon records 1039 points, while the Core i5 manages 892, a 16.5% difference. The single-core result in R20 is also notable: the Xeon scores 146, and the Core i5 scores 126, a 15.9% advantage. This is significant because single-core performance is often where newer architectures close the gap on older, higher-clocked parts. Here, the Xeon's higher base clock of 3.40 GHz overcomes the Core i5's architectural improvements, even with the Core i5's 2.70 GHz boost.

The Cinebench R23 results reinforce the pattern. In multi-core, the Xeon scores 2475 versus the Core i5's 2125, a 16.5% lead. In single-core, the Xeon scores 349 against 300, a 16.3% advantage. These percentages are remarkably consistent, hovering around the 16% mark across all five tests. This suggests that the performance delta is not workload-dependent in a meaningful way; the Xeon's advantage is a uniform multiplier across the entire Cinebench suite.

The Core i5-5200U has additional benchmarks recorded in the database that the Xeon does not have, specifically Geekbench multi-core and single-core scores of 1464 and 742, respectively. These are not part of the head-to-head comparison because no corresponding Xeon results exist, but they provide a reference point for the Core i5's absolute performance level in a different benchmark suite.

The Verdict

The data is unambiguous. The Intel Xeon X5492 outperforms the Intel Core i5-5200U in every recorded benchmark, with a consistent margin of approximately 16% across multi-core and single-core tests in Cinebench R15, R20, and R23. The Xeon's 5 wins and 0 losses in the head-to-head comparison make it the clear choice for anyone prioritizing raw compute performance, regardless of workload type.

Who should pick the Xeon? Based on the data, it is for users who need maximum processing throughput and are not constrained by power consumption or physical footprint. Its server/workstation market segment, ECC memory support, and 150 W TDP indicate it belongs in a desktop or rack-mounted system where sustained load is expected. The 23rd percentile ranking among all CPUs in the database, while modest in the broader context, still places it ahead of the Core i5's 22nd percentile. Its average benchmark score of 852 is also higher than the Core i5's 838.

Who should pick the Core i5-5200U? The data shows it is a lower-performing part, but its architectural profile tells the rest of the story. Its 15 W TDP, integrated Intel HD 5500 graphics, and mobile socket make it suitable for laptops and ultra-portable devices where the Xeon cannot physically or thermally fit. The Core i5 is not a competitor in raw speed, but its existence is justified by efficiency and integration. The database shows its nearest rivals include the Intel Core i5-3380M and Intel Xeon X3450, with average scores of 838 and 837 respectively, indicating it sits in a different performance class entirely. For a user with a fixed need for high compute, the Xeon is the only rational choice from these two options.
