Intel Xeon D-2712T vs Intel Xeon E3-1585L v5 Comparison

Head-to-Head Benchmarks

The recorded data shows a consistent, though narrow, victory for the Intel Xeon E3-1585L v5 across every Cinebench workload in the comparison. In Cinebench R15 multi-core, the E3-1585L v5 scores 693 against 684 for the Xeon D-2712T, a 1.3% advantage. The single-core result in the same test is 97 versus 96, a 1% lead. Moving to Cinebench R20, the multi-core margin remains at 1.3%: 2888 for the E3-1585L v5 against 2852 for the D-2712T. Single-core in R20 shows 407 versus 402, a 1.2% edge.

The pattern holds in Cinebench R23, the most demanding workload listed. Multi-core scores are 6878 for the E3-1585L v5 and 6791 for the D-2712T, again a 1.3% gap. Single-core in R23 is 971 versus 958, the largest relative difference in the set at 1.4%. In total, the E3-1585L v5 wins all six head-to-head benchmarks. The Xeon D-2712T records zero wins in this comparison.

These margins are small enough that they fall within run-to-run variance for many systems. The data indicates the E3-1585L v5 has a slight but repeatable edge in every measured workload. For a builder deciding between these two, the benchmark difference is real but not transformative. The average benchmark score for the E3-1585L v5 is 1989, while the D-2712T sits at 1964, a gap of roughly 1.3% overall. Both processors land at the 44th percentile among all CPUs in the database, meaning they occupy the same performance tier relative to the broader market.

Where Each One Wins

The Intel Xeon E3-1585L v5 wins in all six recorded Cinebench tests, covering both multi-core and single-core workloads across R15, R20, and R23. This makes it the clear choice for any application that relies on raw CPU throughput, whether that is rendering, code compilation, or general productivity. Its advantage is consistent, ranging from 1% in Cinebench R15 single-core to 1.4% in Cinebench R23 single-core. Multi-core gaps are uniformly 1.3% across all three Cinebench versions.

The Intel Xeon D-2712T does not win a single benchmark in this comparison. However, its performance is close enough that the practical difference is minimal. The data shows the D-2712T trailing by only a few points in each test, which means users with lightly threaded workloads or mixed usage patterns would likely not perceive a difference. Where the D-2712T does differentiate itself is in platform features, not in raw benchmark scores. It offers quad-channel memory support with 85.3 GB/s bandwidth, double the 34.1 GB/s of the E3-1585L v5, and 32 PCIe Gen 4 lanes versus 16 Gen 3 lanes. For workloads that are memory-bandwidth sensitive or need more PCIe connectivity, the D-2712T provides a structural advantage even if its Cinebench numbers are slightly lower.

Architecture Differences

The two processors come from different Intel generations and manufacturing nodes. The E3-1585L v5 uses the Skylake-H architecture on a 14 nm process, with 2,300 million transistors and a die size of 171 mm². The D-2712T uses the Ice Lake-D architecture on a 10 nm node, though transistor count and die size are not recorded in the database. This node difference is significant: the smaller 10 nm process allows for a more modern design, but the E3-1585L v5 compensates with a higher base clock of 3.00 GHz and boost clock of 3.70 GHz. The D-2712T has a base clock of 1900.00 MHz and a boost clock of 3.00 GHz, meaning it runs at lower frequencies across the board.

Cache layouts also differ substantially. The E3-1585L v5 has 64 KB L1 per core, 256 KB L2 per core, and 8 MB shared L3. The D-2712T has 80 KB L1 per core, 1.25 MB L2 per core, and 15 MB shared L3. The D-2712T's larger per-core L2 and nearly double L3 cache help compensate for its lower clock speeds, which explains why the benchmark gap stays so small. Both processors have 4 cores and 8 threads, so thread count is identical.

Memory support is another clear split. The E3-1585L v5 supports both DDR3 and DDR4 with a dual-channel bus and 34.1 GB/s bandwidth. The D-2712T supports only DDR4 but uses a quad-channel bus with 85.3 GB/s bandwidth. This is a major architectural difference: the D-2712T can move data at 2.5 times the rate of the E3-1585L v5. PCIe support also differs: the E3-1585L v5 provides 16 Gen 3 lanes, while the D-2712T offers 32 Gen 4 lanes. The D-2712T has no integrated graphics, whereas the E3-1585L v5 includes Iris Pro Graphics P580.

The sockets are incompatible: the E3-1585L v5 uses Intel BGA 1440, while the D-2712T uses Intel BGA 2579. The E3-1585L v5 was released on 2016-05-30 and is marked end-of-life, while the D-2712T was released on 2022-02-23 and remains active in production.

The Verdict

The data points to a straightforward conclusion for raw benchmark performance: the Intel Xeon E3-1585L v5 is the faster processor in every recorded Cinebench test. Its advantages range from 1% to 1.4%, which is modest but consistent. For workloads that are purely CPU-bound, the E3-1585L v5 delivers slightly better results across the board. Its higher clock speeds, both base and boost, directly contribute to this edge.

However, the Xeon D-2712T is not without justification. Its quad-channel memory support with 85.3 GB/s bandwidth is a major advantage for memory-intensive tasks that are not well represented in Cinebench. The 32 PCIe Gen 4 lanes also make it a better fit for systems with high-bandwidth peripherals like NVMe storage arrays or multiple accelerators. Its larger L3 cache of 15 MB versus 8 MB may help in workloads with large working sets.

The E3-1585L v5 is the choice for someone who cares about maximum single-thread and multi-thread CPU performance in a low-power envelope, with a 45 W TDP versus 65 W for the D-2712T. The D-2712T is the choice for someone building around memory bandwidth and PCIe expansion, where its modern platform features offset a small benchmark deficit. Both processors sit at the 44th percentile, so neither is a class-leading part. The E3-1585L v5 wins the benchmark comparison outright, but the D-2712T offers a more capable platform for data-heavy server workloads. Given that the E3-1585L v5 is end-of-life and the D-2712T is still active, availability will likely favor the newer part. Pick the E3-1585L v5 for pure CPU speed, pick the D-2712T for platform breadth.
