Intel Core i5-5200U vs Intel Xeon X5470 Comparison

The Intel Xeon X5470 and Intel Core i5-5200U represent two vastly different design philosophies from Intel, separated by nearly seven years of architectural evolution. The Xeon is a server-class quad-core from the Core 2 era, while the i5 is a mobile dual-core from the Broadwell generation. Despite their differences, benchmark data places them in an unusually tight average performance band, with the Xeon averaging 839 points and the i5 at 838 points. This near-parity in aggregate scores, however, masks a decisive split in individual workload results, where the older Xeon consistently outperforms the newer mobile chip across every tested Cinebench scenario.

Head-to-Head Benchmarks

The head-to-head benchmark results are remarkably one-sided. Across all five Cinebench tests, the Intel Xeon X5470 emerges victorious, with the Core i5-5200U failing to win a single comparison. The margins are consistent, hovering in a narrow band between 14.3% and 14.8%. In Cinebench R15 multi-core, the Xeon scores 245 against the i5’s 214, a 14.5% advantage. This pattern repeats in Cinebench R20 multi-core, where the Xeon posts 1024 versus 892, a 14.8% lead.

Single-core results tell a similar story. In Cinebench R20 single-core, the Xeon achieves 144 points compared to the i5’s 126, a 14.3% delta. The R23 single-core test shows the Xeon at 344 and the i5 at 300, a 14.7% margin. The largest relative gap appears in both R20 and R23 multi-core tests at 14.8%, while the smallest is in R20 single-core at 14.3%. These consistent margins suggest a fundamental throughput advantage for the Xeon that scales uniformly across rendering workloads, regardless of thread count or instruction set generation.

The aggregate benchmark scores reinforce this picture. The Xeon’s average benchmark score of 839 places it just 0.2% above the i5-5200U’s 838, yet that tiny aggregate difference obscures the fact that the Xeon wins every discrete test. The nearest rival data shows the Xeon at 0.2% ahead of the i5-5200U, while the i5 is 0.2% behind the Xeon. This is a statistical near-tie in overall standing, but the head-to-head table reveals a clear, repeatable performance hierarchy: the Xeon is faster in every measured scenario.

Where Each One Wins

The Intel Xeon X5470 wins in all rendering-focused benchmarks. Its 5-0 record in the head-to-head comparison means it is the superior choice for any workload that relies on Cinebench-style multi-threaded or single-threaded rendering. The Xeon’s four physical cores operating at 3.33 GHz base clock provide a raw compute advantage that the i5’s two cores with Hyper-Threading cannot overcome, even when the i5 boosts to 2.70 GHz. For users running CPU-bound render tasks, video encoding, or scientific simulations that scale with core count and clock speed, the Xeon’s consistent 14%+ lead makes it the definitive performer.

The Core i5-5200U, despite losing every head-to-head test, holds advantages in areas not captured by the Cinebench suite. It includes integrated Intel HD 5500 graphics, which the Xeon lacks entirely, making the i5 functional for systems without a discrete GPU. The i5 also supports a memory bandwidth of 25.6 GB/s, a specification not listed for the Xeon, and it does so within a 15-watt thermal envelope versus the Xeon’s 120-watt TDP. The i5 is the only option for compact, fanless, or battery-powered designs, and its lower power draw enables deployment in Ultrabook-style chassis where the Xeon’s server-oriented socket 771 cannot physically fit.

For workloads that are not represented in the benchmark data, the i5 offers modern features absent from the Xeon. The i5’s 14 nm process node versus the Xeon’s 45 nm node means dramatically better power efficiency per unit of work. The i5’s transistor count of 1,300 million exceeds the Xeon’s 820 million, and its 82 mm² die size is far smaller than the Xeon’s dual-die 2x 107 mm² configuration. In purely mobile or low-power scenarios, the i5 is the only viable choice, but for raw compute performance, the Xeon dominates.

The Verdict

The data is unambiguous for performance-focused buyers: the Intel Xeon X5470 outperforms the Intel Core i5-5200U in every benchmark recorded. With a 14.5% lead in R15 multi-core, 14.8% in R20 multi-core, and 14.7% in R23 single-core, the Xeon is the faster processor for any rendering workload. Its four physical cores at 3.33 GHz provide a structural advantage that two Broadwell cores, even with Hyper-Threading and a 2.70 GHz boost, cannot match. The Xeon also supports ECC memory, a feature absent from the i5, making it suitable for error-sensitive server or workstation tasks. Its 22nd percentile ranking among all CPUs matches the i5’s 22nd percentile, but within this pairing, the Xeon is the clear winner.

However, the Core i5-5200U is not without its own merits. It is the only one of the two with integrated graphics, and its 15-watt TDP is one-eighth of the Xeon’s 120-watt draw. The i5’s 14 nm process and 1,300 million transistors represent a more modern design, and its BGA 1168 socket enables ultra-thin laptop integration. For users who prioritize portability, battery life, and silent operation over peak compute performance, the i5 is the appropriate choice. Its launch MSRP of $281 also reflects its mobile-market positioning, though that figure should not be interpreted as a value comparison.

The verdict hinges on use case. If the task is sustained multi-threaded rendering or single-threaded responsiveness in a desktop or server chassis, the Xeon X5470 is the superior processor by every measured metric. If the task is general-purpose mobile computing where power draw and physical size are constraints, the i5-5200U is the only feasible option, and its performance deficit is a necessary trade-off for its mobility. The data shows no scenario in the tested benchmarks where the i5 wins, so the Xeon is the recommended choice for raw performance.

Architecture Differences

The architectural divide between these two processors is substantial. The Intel Xeon X5470 is built on the Core 2 architecture with the codename Harpertown, using a 45 nm process node manufactured by Intel. It contains 820 million transistors spread across two dies, each measuring 107 mm², for a total die size of 2x 107 mm². The Xeon features four cores and four threads, with no Hyper-Threading, running at a base clock of 3.33 GHz with no boost clock. Its cache hierarchy includes 64 KB of L1 per core and 6 MB of L2 per die, with no L3 cache listed. It supports dual-channel DDR2 and DDR3 memory, with ECC capability, and connects via PCIe Gen 2. The Xeon uses the Intel Socket 771 and has a TDP of 120 watts.

The Intel Core i5-5200U is built on the Broadwell architecture with the codename Broadwell-U, using a 14 nm process node. It contains 1,300 million transistors on a single die measuring 82 mm². The i5 has two cores and four threads, enabling Hyper-Threading, with a base clock of 2.20 GHz and a boost clock of 2.70 GHz. Its cache includes 64 KB of L1 per core, 256 KB of L2 per core, and 3 MB of shared L3 cache. It supports dual-channel DDR3 memory with 25.6 GB/s bandwidth, but does not support ECC. The i5 includes integrated Intel HD 5500 graphics and connects via PCIe Gen 2 with 12 lanes from the CPU. It uses the Intel BGA 1168 socket and has a TDP of just 15 watts.

The process node difference is the most striking: 45 nm versus 14 nm represents a three-generation leap in manufacturing. The Xeon’s dual-die design and lack of L3 cache contrast sharply with the i5’s monolithic die and shared L3. The Xeon’s higher base clock (3.33 GHz vs 2.20 GHz) compensates for its older architecture, while the i5’s boost clock of 2.70 GHz helps close the gap in single-threaded tasks. The Xeon’s server market segment and ECC support make it suited for reliability-critical workloads, while the i5’s mobile segment and integrated graphics target low-power consumer devices. Both processors are end-of-life, with the Xeon released in 2008 and the i5 in 2015, yet the older part remains faster in rendering benchmarks due to its core count and clock speed advantage.
