Intel Xeon E3-1230 v5

Intel Xeon E3-1230 v5 is a 14 nm Skylake-DT server/workstation processor with 4 cores and 8 threads. It uses Intel Socket 1151 and supports both DDR3 and DDR4 memory in a dual-channel configuration, with ECC support enabled. The memory controller delivers 34.1 GB/s of bandwidth. PCIe connectivity is Gen 3 with 16 lanes from the CPU only, and there is no integrated graphics, so a separate GPU must be present. The processor has an average benchmark score of 1965, placing it at the 46th percentile of all CPUs. It launched on 2015-10-18 and its production status is end-of-life.

Platform and Compatibility

The Xeon E3-1230 v5 belongs to the Skylake-DT generation. The base clock is 3.40 GHz, with a boost clock of 3.80 GHz. It is a 4-core, 8-thread part with 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 8 MB of shared L3 cache. The cache layout is small by modern standards, but it is paired with server-oriented platform features: DDR3 and DDR4 support, dual-channel memory, ECC capability, and a 34.1 GB/s memory bus.

The PCIe implementation is Gen 3 with 16 lanes, and the fact pack notes that these are CPU-only lanes. That distinction matters because the data does not describe additional chipset lanes; expansion capacity is tied to the CPU's own lanes. This is a typical arrangement for a compact workstation processor. There is no integrated graphics, so the platform requires a discrete GPU for display output. That aligns with the Server/Workstation market segment.

The socket is Intel Socket 1151, which anchors the upgrade path to that socket generation. The part number is SR2LE. The multiplier is locked, so conventional overclocking is not supported. The processor was released on 2015-10-18 and has since moved to end-of-life status. The launch MSRP was $261. For anyone building a new system today, the lack of production availability is the dominant practical factor.

Power and Thermals

This processor has a TDP of 80 W. On a 14 nm process with 1,750 million transistors and a die size of 122 mm², that power envelope is modest. The data implies a mainstream cooling class: an 80 W CPU does not require the cooling hardware associated with high-end, high-TDP parts. Because there is no integrated graphics, the thermal load comes almost entirely from the 4-core/8-thread compute die.

The combination of process node, transistor count, and die size helps explain the thermal behavior. 1,750 million transistors on 122 mm² is a dense footprint for the era, and the 80 W TDP suggests the 3.40 GHz base and 3.80 GHz boost clocks are sustainable within that thermal class. For workstation chassis designers, an 80 W part is easier to cool in a compact layout than high-core-count server chips. The locked multiplier further keeps thermals predictable, since users cannot raise clocks through overclocking.

Benchmark Performance

The Cinebench results give a broad view of where this part stands. In Cinebench R15, it scores 684 multi-core and 96 single-core. In R20, the scores are 2853 multi-core and 402 single-core. In R23, the scores are 6794 multi-core and 959 single-core. Across all benchmarks, the average benchmark score is 1965. The 46th percentile ranking means the processor sits just below the midpoint of the database distribution. That is neither a low-end nor a high-end position.

The nearest rivals show how tight the competition is at this score level. The Intel Xeon D-2712T has an average score of 1964, which is 0.1% behind the E3-1230 v5. The Intel Core i7-3930K averages 1963, also 0.1% behind. On the other side, the AMD Ryzen 5 2600H averages 1967, 0.1% ahead, and the AMD Ryzen 3 2300X averages 1968, 0.2% ahead. The entire nearest-rival group is separated by fractions of a percent. In practical terms, the ordering among these processors could easily shift from one benchmark run to the next.

The multi-core Cinebench scores are substantially larger than the single-core scores, which is expected for a CPU with 4 cores and 8 threads. But the average benchmark score is what feeds the percentile and rival comparisons, and that average places the Xeon in a tightly packed cluster of processors. The data suggests the E3-1230 v5 is competitive in aggregate, but it is not clearly faster than any of its nearest rivals.

FAQ

Q: Does the Intel Xeon E3-1230 v5 support ECC memory?

A: Yes. ECC memory support is listed as true, which is a key server/workstation feature.

Q: What socket does this processor use?

A: It is built for Intel Socket 1151.

Q: Does it have integrated graphics?

A: No. Integrated graphics is not listed, so a separate graphics card is required for display output.

Q: Is the processor overclockable?

A: No. The multiplier is locked, so the data does not support overclocking.

Q: What memory types are supported?

A: DDR3 and DDR4 are both supported, over a dual-channel memory bus with 34.1 GB/s of bandwidth.

Q: Is this processor still in production?

A: No. The production status is end-of-life.

Who Should Consider It

The market segment is Server/Workstation, and the feature set follows that role. ECC memory support is the clearest signal: anyone who needs memory error detection and correction in a compact 4-core/8-thread platform is the intended user. The lack of integrated graphics also points toward workstation builds where a discrete GPU is already assumed.

In terms of workload, the single-core Cinebench R23 score of 959 suggests that lightly threaded office or engineering applications will see reasonable responsiveness. The multi-core R23 score of 6794 indicates moderate parallel throughput, enough for occasional rendering, video encoding, or compilation work, but not for sustained heavy compute. The 46th percentile average ranking reinforces that this is not a flagship rendering CPU.

The locked multiplier matters for users who expect to tune performance; this part is not designed for that. The end-of-life status matters for users who need long-term supply. The feature set overall is aimed at a specific niche: ECC-capable, single-socket workstations where memory reliability and a modest core count are more important than raw multi-thread dominance.

Single-Thread vs Multi-Thread Behavior

The split between single-core and multi-core scores is one of the clearest patterns in the data. In Cinebench R15, the multi-core score is 684 against a single-core score of 96. In R20, the multi-core score is 2853 against 402 single-core. In R23, the multi-core score is 6794 against 959 single-core. Every Cinebench generation shows the same shape: the multi-core result is far larger than the single-core result because all 8 threads can be engaged.

Real applications do not all behave this way. Some workloads, such as interactive analysis tools, UI-driven applications, or lightly threaded legacy software, will mostly stay in the single-core regime. Those tasks will use only a fraction of the available throughput. Other workloads, such as batch rendering, video export, or CPU-based simulation, can spread work across 8 threads and will get closer to the multi-core scores.

The base clock of 3.40 GHz and boost clock of 3.80 GHz are the clocks that govern single-thread execution. A higher single-core score indicates how responsive the CPU feels in tasks that cannot parallelize. The multi-core scores indicate how much sustained work the processor can complete when all 4 cores and 8 threads are active. For users running serial workloads, the single-core scores are more relevant; for parallel workloads, the multi-core scores dominate. The Xeon sits in a position where neither extreme is outstanding, but both are usable.

How It Compares

Versus the Intel Xeon D-2712T, the E3-1230 v5 is essentially neck-and-neck. The D-2712T averages 1964, a 0.1% lower score than the E3-1230 v5's 1965. This is the closest rival in the set. The two processors are so close that workload-specific benchmarks would be needed to separate them.

Versus the Intel Core i7-3930K, the picture is similar. The i7-3930K averages 1963, 0.1% behind. This comparison spans different points in Intel's product stack, yet the aggregate scores land almost exactly together. The E3-1230 v5 is neither clearly faster nor clearly slower in average terms.

Versus the AMD Ryzen 5 2600H, the E3-1230 v5 trails slightly. The Ryzen 5 2600H averages 1967, which is 0.1% ahead. Again, the gap is small enough that no decisive winner appears. The ordering in a specific test could differ from the average.

Versus the AMD Ryzen 3 2300X, the gap is the largest among the nearest rivals. The Ryzen 3 2300X averages 1968, 0.2% ahead of the E3-1230 v5. Even this largest gap is minor on the absolute scale. The data places the Xeon in a tight band of closely matched average scores, with no competitor holding a meaningful lead.
