AMD Ryzen 7 2800H vs Intel Xeon E3-1285L v4 Comparison

The AMD Ryzen 7 2800H and Intel Xeon E3-1285L v4 are both 4-core, 8-thread processors, but they target entirely different market segments: one is a low-power mobile chip, the other a server/workstation part. The benchmark data reveals a remarkably close contest, with the AMD part winning every single head-to-head test, but by margins so slim they fall within typical run-to-run variance. The real story here is not about raw speed, but about how each chip's architectural choices and platform positioning shape its suitability for different workloads.

Head-to-Head Benchmarks

The most striking finding from the data is the consistency of the AMD Ryzen 7 2800H's victory. Across six Cinebench tests—spanning R15, R20, and R23, and covering both single-core and multi-core workloads—the AMD chip wins every time. However, the margins are extraordinarily narrow. In the multi-core tests, the Ryzen 7 2800H posts a 697 in Cinebench R15 versus the Xeon's 693, a delta of just 0.6%. That same 0.6% gap repeats in Cinebench R20 (2907 vs 2891) and R23 (6922 vs 6884). This is not a decisive performance advantage; it is a statistical tie masquerading as a clean sweep.

Single-core results follow the same pattern. The Ryzen 7 2800H edges ahead with a 98 in Cinebench R15 single-core versus the Xeon's 97, a 1% lead. In R20, the gap narrows to 0.7% (410 vs 407), and in R23 it settles back to 0.6% (977 vs 971). While the AMD chip wins all six benchmarks, the data suggests that the two processors are functionally equivalent in terms of raw compute throughput. A 0.6% to 1% difference is negligible in real-world applications, and any user would be hard-pressed to notice the distinction.

The aggregate benchmark scores tell the same story. The Ryzen 7 2800H's average benchmark score is 2002, while the Xeon E3-1285L v4 sits at 1991. That is an 11-point difference, roughly 0.5%. Both chips land in the 44th to 45th percentile of all CPUs, placing them in the same performance tier. The nearest rivals list for each chip further reinforces this: the Ryzen's closest competitor is the Intel Core i5-8400T (avg score 2001, 0% delta), while the Xeon's closest is the AMD Ryzen 5 1500X (avg score 1992, 0% delta). In essence, these two chips are so close that they compete with each other's direct rivals.

Where Each One Wins

Given that the Ryzen 7 2800H wins all six head-to-head tests, it is tempting to declare it the outright winner. But the data demands a more nuanced interpretation. The performance deltas are so small—all under 1%—that they are unlikely to be perceptible in any practical application. The real differentiation lies elsewhere, in the platform and feature differences that go beyond raw Cinebench scores.

The Ryzen 7 2800H's wins are consistent but marginal. In multi-threaded workloads like video rendering or 3D modeling, the 0.6% lead in Cinebench R23 multicore (6922 vs 6884) would translate to a difference of mere seconds over hours of compute time. In single-threaded tasks, such as office productivity or web browsing, the 0.6% to 1% advantage is utterly imperceptible. The Ryzen's wins are real in a numerical sense, but they do not constitute a meaningful performance victory.

The Xeon E3-1285L v4, despite losing all six benchmarks, wins in areas that the Cinebench scores do not capture. It supports ECC memory, a critical feature for server and workstation environments where data integrity is paramount. It also has a higher memory bandwidth rating of 29.9 GB/s, although the Ryzen's memory bandwidth is not specified in the data, making a direct comparison impossible. The Xeon also carries a launch MSRP of $445, but pricing considerations aside, its platform—Intel Socket 1150 with DDR3 memory support—positions it for legacy workstation builds where ECC and stability are the priority.

The Ryzen 7 2800H, by contrast, is a mobile part with a 15W TDP, making it suitable for thin-and-light laptops. Its integrated Radeon RX Vega 11 graphics are likely more capable for light gaming or media playback than the Xeon's Intel Iris Pro P6300, though the data does not provide direct graphics benchmarks. The Ryzen's wins are in efficiency and portability, not in raw compute.

The Verdict

From the data alone, the AMD Ryzen 7 2800H is the technically faster processor, winning all six head-to-head tests. However, the margins are so thin that they should be considered a tie in practical terms. A 0.6% lead in multi-core and a 0.7% to 1% lead in single-core will not change the outcome of any real workload. The choice between these two chips should be driven entirely by platform requirements.

The Ryzen 7 2800H is the pick for mobile or low-power applications. Its 15W TDP is dramatically lower than the Xeon's 65W, making it the only viable option for laptops or compact systems where thermal and power budgets are tight. It also features the newer Zen architecture and a smaller die size of 246 mm², though the Xeon's die is even smaller at 160 mm² with fewer transistors (1,400 million vs. unspecified for the Ryzen). For users building a power-efficient system, the Ryzen is the clear choice.

The Xeon E3-1285L v4 is the pick for legacy server or workstation builds on the Intel Socket 1150 platform. Its ECC memory support is a decisive advantage for error-sensitive computing, such as financial modeling or scientific simulations. Although it is end-of-life and draws significantly more power, the data shows it delivers essentially identical performance to the Ryzen. If the platform requires ECC or DDR3 memory, the Xeon is the only option.

Architecture Differences

The two processors represent fundamentally different architectural approaches from their respective manufacturers. The AMD Ryzen 7 2800H is built on the Zen architecture with the codename "Raven Ridge," part of the Ryzen 7 generation. It uses a 14 nm process node fabricated by GlobalFoundries, with a die size of 246 mm². Its cache hierarchy includes 128 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3 cache. The chip integrates Radeon RX Vega 11 graphics and supports DDR4 memory in a dual-channel configuration, but it lacks ECC support and PCIe details are unspecified.

The Intel Xeon E3-1285L v4, in contrast, is built on the Broadwell architecture with the codename "Broadwell-DT." It also uses a 14 nm process node, but fabricated by Intel, with a significantly smaller die size of 160 mm² and a transistor count of 1,400 million. Its cache is smaller per-core—64 KB of L1 and 256 KB of L2—but it compensates with a larger 6 MB of shared L3 cache. The Xeon supports DDR3 memory in a dual-channel configuration with a rated bandwidth of 29.9 GB/s, and it includes ECC memory support. It integrates Intel Iris Pro P6300 graphics and uses PCIe Gen 3. The Xeon is a server/workstation part, while the Ryzen is a mobile part.

Specification Differences

The most consequential specification difference is the TDP: the Ryzen 7 2800H draws just 15W, while the Xeon E3-1285L v4 draws 65W. This 50W gap fundamentally changes the thermal envelope and power supply requirements. The Ryzen uses an AMD Socket FP5, while the Xeon uses an Intel Socket 1150. Memory support diverges sharply: the Ryzen uses DDR4 with no ECC, while the Xeon uses DDR3 with ECC enabled and a specified bandwidth of 29.9 GB/s. The Ryzen's L1 cache is 128 KB per core versus the Xeon's 64 KB, and L2 is 512 KB per core versus 256 KB, but the Xeon has more L3 cache (6 MB shared vs 4 MB shared). The Ryzen has an integrated Radeon RX Vega 11 GPU, while the Xeon has Intel Iris Pro P6300. The Xeon has a launch MSRP of $445, while the Ryzen's is not specified. The Ryzen is marked as active production and released in 2018, while the Xeon is end-of-life and released in 2015. The Xeon also lists a part number (SR2B1) and PCIe Gen 3 support, whereas the Ryzen's PCIe details are not provided.
