AMD Ryzen 5 2500X vs Intel Xeon E3-1285 v6 Comparison

FAQ

Q: Which CPU has the higher average benchmark score?

A: The AMD Ryzen 5 2500X posts an average benchmark score of 2361, while the Intel Xeon E3-1285 v6 scores 2348. That puts the AMD part 0.6% ahead when looking at the nearestRivals deltaPct data.

Q: Are these two CPUs in the same performance class?

A: Yes. Both sit at the 48th percentile among all CPUs. The Xeon E3-1285 v6’s nearest rivals include the Ryzen 5 2500X at a -0.5% deltaPct, and the Ryzen’s nearest rivals include the Xeon at a +0.6% deltaPct, indicating they are effectively neck-and-neck in overall performance.

Q: What are the clock speed differences between the two?

A: The Intel Xeon E3-1285 v6 has a 4.10 GHz base clock and a 4.50 GHz boost clock. The AMD Ryzen 5 2500X runs at a 3.60 GHz base and 4.00 GHz boost. The Xeon is higher on both counts.

Q: Which CPU has integrated graphics?

A: Only the Intel Xeon E3-1285 v6, which includes HD Graphics P630. The AMD Ryzen 5 2500X has no integrated graphics listed.

The Verdict

The benchmark data is unambiguous: the Intel Xeon E3-1285 v6 wins every single head-to-head test in the comparison. It takes all six benchmarks — Cinebench R15, R20, and R23, both single-core and multi-core — with a consistent 1% margin (or 0.9% in R15 single-core). If you are choosing strictly on measured performance, the Xeon is the pick.

That said, the margin is thin. The Ryzen 5 2500X’s average benchmark score of 2361 actually edges out the Xeon’s 2348, and the deltaPct between them in the rivals lists is under 1% in either direction. The Ryzen also has a lower 65W TDP versus the Xeon’s 79W, which matters for cooling and power-constrained builds.

Who should pick the AMD Ryzen 5 2500X? Builders who prioritize lower power draw, a modern 12 nm process node, an unlocked multiplier for overclocking, and the AMD Socket AM4 platform. The data shows it is essentially tied in overall average score despite losing every direct benchmark.

Who should pick the Intel Xeon E3-1285 v6? Users who need ECC memory support, integrated graphics, higher clock speeds, and a server/workstation market segment. It also has a slight edge in every single measured test, so if you want the outright winner in this specific matchup, the Xeon takes it.

Neither CPU is a clear value winner because both are within 0.6% of each other in average score. The decision comes down to platform features, power efficiency, and whether you need the Xeon’s workstation-oriented extras.

Head-to-Head Benchmarks

The Intel Xeon E3-1285 v6 sweeps all six benchmarks in the head-to-head table. It wins Cinebench R15 multi-core with 818 versus 810, a 1% deltaPct. In R15 single-core, it scores 115 against 114, a 0.9% edge. The pattern repeats in R20: multi-core 3409 versus 3375 (1% deltaPct), single-core 481 versus 476 (1% deltaPct). In R23, the Xeon posts 8119 against 8036 in multi-core and 1146 against 1134 in single-core, both at 1% deltaPct.

The largest absolute gap is in R23 multi-core, where the Xeon leads by 83 points. The smallest is R15 single-core, where a single point separates them. Across all tests, the deltaPct never exceeds 1%, meaning these are closely matched silicon.

Looking at the broader benchmark picture, the Ryzen 5 2500X has additional Geekbench results that the Xeon does not list: 3813 multi-core and 1126 single-core. The Xeon has no Geekbench entries in the data, so a direct comparison there is impossible. The Ryzen’s average benchmark score of 2361 comes from eight tests, while the Xeon’s 2348 comes from six.

The wins for the Xeon are consistent but narrow. A 1% margin in Cinebench is within run-to-run variance on many systems, so the practical difference in real-world rendering is minimal. However, the data shows the Xeon ahead in every recorded test, which is a clean sweep.

Specification Differences

The two CPUs share several core specifications: both have 4 cores and 8 threads, both use DDR4 memory in a dual-channel configuration, and both support PCIe Gen 3 with 16 lanes from the CPU. After that, the differences stack up.

Clock speeds favor the Intel part. The Xeon E3-1285 v6 runs at 4.10 GHz base and 4.50 GHz boost, while the Ryzen 5 2500X sits at 3.60 GHz base and 4.00 GHz boost. The Xeon’s 0.5 GHz higher base clock and 0.5 GHz higher boost clock explain its consistent benchmark wins.

TDP differs significantly. The Ryzen draws 65W, the Xeon draws 79W. That 14W gap makes the AMD part more power-efficient on paper, likely contributing to its similar average score despite lower clocks.

Socket and platform are completely different. The Ryzen uses AMD Socket AM4, the Xeon uses Intel Socket 1151. The Ryzen has an unlocked multiplier, the Xeon is locked. The Ryzen is marked as Active production status, while the Xeon’s production status is not listed.

Memory features diverge on ECC. The Xeon supports ECC memory, the Ryzen does not. The Ryzen lists a memory bandwidth of 46.9 GB/s, the Xeon does not provide that figure.

The integrated graphics situation is exclusive to Intel: HD Graphics P630 is present on the Xeon, while the Ryzen has no iGPU listed.

Release dates differ by over a year. The Ryzen launched on 2018-09-09, the Xeon on 2017-07-31. The Ryzen’s part number is YD250XBBM4KAFYD250XBBAFMPK, the Xeon’s is SR373.

Architecture Differences

The process nodes are different generations. The AMD Ryzen 5 2500X is built on a 12 nm process at GlobalFoundries, while the Intel Xeon E3-1285 v6 uses a 14 nm process at Intel. The Ryzen’s smaller node comes with a larger transistor count: 4,800 million versus 1,400 million. The die sizes also differ, with the Ryzen at 213 mm² and the Xeon at 160 mm².

Both use the Zen and Kaby Lake architectures respectively. The Ryzen is codenamed Zen (with generation listed as Zen+ Pinnacle Ridge), the Xeon is Kaby Lake-DT. The Ryzen is part of AMD’s 2000 series, while the Xeon has no series designation.

Cache layouts are similar in total but differ per core. Both have 8 MB of shared L3 cache. The Ryzen has 96 KB of L1 per core and 512 KB of L2 per core. The Xeon has 64 KB of L1 per core and 256 KB of L2 per core. That means the Ryzen has larger per-core L1 and L2, while the Xeon’s higher clocks compensate.

The Ryzen’s architecture is newer by roughly a year in release timing. Its 12 nm node and higher transistor count suggest a denser design, but the benchmark results show that does not translate into a performance lead. The Xeon’s older 14 nm Kaby Lake design still wins every test, likely due to its substantial clock advantage.

The integrated graphics on the Xeon are part of its architecture, while the Ryzen has none. The Xeon also carries ECC support in its memory controller, a feature absent from the Ryzen.

Where Each One Wins

The Intel Xeon E3-1285 v6 wins in every direct benchmark comparison: six out of six tests. It is the choice for anyone who wants the measured performance leader in Cinebench R15, R20, and R23, regardless of single-core or multi-core workload. The Xeon’s higher base and boost clocks give it a consistent edge in both rendering and lightly threaded tasks.

The Xeon also wins on features: ECC memory support for reliability-conscious workstation builds, integrated HD Graphics P630 for systems without a discrete GPU, and a server/workstation market segment designation.

The AMD Ryzen 5 2500X wins on the average benchmark score comparison, 2361 versus 2348, and on power efficiency with a 65W TDP versus 79W. It also has a smaller 12 nm process node, a newer release date, and an unlocked multiplier for overclocking. The Ryzen’s larger per-core L1 and L2 caches and its 46.9 GB/s memory bandwidth are documented advantages.

For use cases, the split is clear. If you need ECC, integrated graphics, or maximum Cinebench scores, the Xeon is the data-backed pick. If you want lower power draw, a modern socket with unlocked overclocking, and a slightly higher average benchmark score, the Ryzen is the choice.

In rendering workloads, the Xeon’s 1% margin in R23 multi-core is real but small. In single-core tasks, the Xeon’s 0.9% to 1% edge is equally thin. Neither CPU dominates; the Xeon wins by a nose in every test, while the Ryzen wins the aggregate average.

The practical advice: pick the Xeon for server-like features and guaranteed benchmark wins, pick the Ryzen for efficiency, overclocking, and a platform with a longer upgrade path on AM4. The data supports either decision, depending on which factors you weight more heavily.
