Intel Xeon E3-1225 v5

Intel Xeon E3-1225 v5 is a 4-core, 4-thread Skylake-DT processor from Intel’s Server/Workstation segment. It was released on 2015-10-18 with a launch MSRP of $224, running at a 3.30 GHz base clock and a 3.70 GHz boost clock. The chip has an 80 W TDP, HD Graphics P530 integrated graphics, and an average benchmark score of 1461, which places it in the 39th percentile of all CPUs in the database.

Single-Thread vs Multi-Thread Behavior — what the split means for real workloads

Across three Cinebench versions, the E3-1225 v5 shows a clear split. In Cinebench R15, the single-core score is 71 and the multi-core score is 509. In R20, single-core is 299 and multi-core is 2122. In R23, single-core is 713 and multi-core is 5053. The multi-core scores are much larger, but the chip has only four cores and four threads, so that result comes from four physical cores working together rather than from simultaneous multithreading.

The 3.30 GHz base clock and 3.70 GHz boost clock define the single-thread ceiling. Lightly threaded software will tend to rely on those higher clock speeds, while fully threaded workloads can spread across all four cores. The same single-core versus multi-core pattern appears in R15, R20, and R23, which indicates the balance is stable across Cinebench versions. For real workloads, this means programs that cannot use more than one thread will see only the single-core class of performance, while well-parallelized jobs will capture the multi-core scores. A four-thread part like this one is best matched to software that can use every available thread.

Power and Thermals — TDP class, what cooling tier it implies

With a TDP of 80 W, this Xeon belongs to a moderate power class. The 14 nm process, 1,750 million transistors, and 122 mm² die size are all listed in the data, and they point to a modest thermal footprint. The integrated HD Graphics P530 is included in the processor package, so the 80 W envelope covers CPU and graphics capability together.

The multiplier is locked, meaning overclocking is not an intended path, which also reduces the need for extreme cooling. For a server or workstation part, 80 W is a conservative figure. Conventional air cooling should be sufficient for this power class. The dual-channel DDR3/DDR4 memory controller and 34.1 GB/s memory bandwidth matter more for sustained workloads than for thermals. Nothing in the data suggests exotic cooling is required.

Benchmark Performance — analyze scores vs rivals with exact % deltas

The benchmark results put the E3-1225 v5 in a tight cluster. Cinebench R15 multi-core is 509, and single-core is 71. Cinebench R20 multi-core is 2122, and single-core is 299. Cinebench R23 multi-core is 5053, and single-core is 713.

The average benchmark score is 1461, with a 39th percentile standing among all CPUs. The nearest rival, the AMD Ryzen 3 PRO 2200GE, also averages 1461, for a deltaPct of 0. The Intel Core i3-7350K averages 1464, with a deltaPct of -0.2, meaning the Xeon sits 0.2% behind that rival. Both the Intel Core i5-4590S and the Intel Xeon E3-1515M v5 average 1456, with a deltaPct of 0.3, meaning the E3-1225 v5 is 0.3% ahead of each.

The entire nearest-rival group spans from 1456 to 1464, a difference of only a few points in the database’s average metric. Aggregate score is not where this processor stands out. The single-core versus multi-core split, ECC support, and platform features separate it more than average benchmark score.

How It Compares — position vs each nearest rival, one short paragraph per rival

AMD Ryzen 3 PRO 2200GE: The average score is 1461 for both processors, with a 0% delta. This is the closest possible aggregate result. Any real difference between the two would have to come from workload-specific behavior, platform support, or integrated graphics rather than the average score, since the data shows no average performance gap.

Intel Core i3-7350K: The average score is 1464, and the deltaPct of -0.2 places the Xeon 0.2% behind. The average performance difference is negligible. The two parts sit in different market segments, and the Xeon adds ECC memory support, which the data confirms, while the i3’s segment is not listed.

Intel Core i5-4590S: The average score is 1456, and the deltaPct of 0.3 places the Xeon 0.3% ahead. The average scores are nearly identical, so the comparison is essentially a tie in aggregate terms. The Xeon’s 4-core, 4-thread configuration and 14 nm process are the concrete data points that distinguish it.

Intel Xeon E3-1515M v5: The average score is also 1456, again with a deltaPct of 0.3. The E3-1225 v5 is 0.3% ahead. Both are Xeon-branded processors with very similar average scores; the E3-1225 v5’s Socket 1151 support and HD Graphics P530 are the listed differentiating features.

Platform and Compatibility — socket, memory support, PCIe, upgrade path

The E3-1225 v5 uses Intel Socket 1151 and is based on the Skylake-DT architecture on a 14 nm process. It supports both DDR3 and DDR4 memory in a dual-channel configuration, with a listed memory bandwidth of 34.1 GB/s. ECC memory is supported, and the market segment is Server/Workstation.

PCIe connectivity is Gen 3 with 16 lanes from the CPU only. The integrated HD Graphics P530 provides display output without a discrete graphics card. The chip includes 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 8 MB of shared L3 cache. The part number is SR2LJ.

The production status is end-of-life, and the release date is 2015-10-18. The multiplier is locked, so overclocking is not an intended feature. The launch MSRP was $224. Because the platform is Socket 1151 and the processor is end-of-life, the upgrade path is tied to boards of that generation rather than a forward-looking platform.

Who Should Consider It — workload-based recommendations grounded in the scores

The workload fit follows from the benchmark split. Cinebench R23 multi-core 5053 and R20 multi-core 2122 show a capable four-core result for small render jobs and batch workloads that use all threads. The R23 single-core 713 and R20 single-core 299 are lower, so single-thread-heavy software is not the primary strength.

Gaming workloads that depend on high single-thread performance are less well served by a 4-thread processor in the 39th percentile. The integrated HD Graphics P530 is present, but it is an integrated GPU rather than a high-end discrete-class part. Office productivity is plausible: four cores, four threads, a 3.70 GHz boost clock, and integrated graphics cover common desktop tasks.

The clearest audience is server or workstation users who want ECC memory support in a Socket 1151 build. Users with workloads that need more than four threads should look elsewhere, because this chip cannot exceed its 4-core, 4-thread design. The 1461 average score and 39th percentile show it is not a performance leader, but it is a coherent match for constrained workstation tasks.
