Intel Xeon D-2712T vs Intel Xeon E3-1285L v4 Comparison

The Intel Xeon E3-1285L v4 and the Intel Xeon D-2712T are two server-class parts separated by nearly seven years of silicon development, yet the recorded benchmark data shows them performing almost identically. Both are 4-core, 8-thread processors with a 65 W TDP, both sit in the 44th percentile of all CPUs in the database, and across six Cinebench runs the older Broadwell part wins every single time, though never by more than 1.4 percent. The interesting story here is not who wins, but how two architectures from different eras landed on the same performance plateau.

Head-to-Head Benchmarks

The sweep goes six wins to zero in favor of the Xeon E3-1285L v4, but the margins are razor thin across the board.

In Cinebench R15, the E3-1285L v4 scores 693 in multi-core against 684 for the D-2712T, a 1.3 percent gap. Single-core is closer still: 97 versus 96, exactly one percent apart. Cinebench R20 follows the same pattern, with the E3-1285L v4 taking multi-core 2891 to 2852 (a 1.4 percent advantage) and single-core 407 to 402 (1.2 percent).

The newest test in the set, Cinebench R23, produces the largest deltas of the comparison. The E3-1285L v4 posts 6884 in multi-core against 6791 for the D-2712T, and 971 versus 958 in single-core, both 1.4 percent advantages. That the gap holds steady or even widens slightly in the most modern rendering workload is notable, because it means the E3-1285L v4's clock advantage holds up under sustained, current-generation loads rather than fading.

The single consistency across every test is the direction of the result. The E3-1285L v4 leads in all six benchmarks, and no delta in the entire set exceeds 1.4 percent. In practical terms, the two processors are rendering-performance equivalents, with the older part holding a statistical edge everywhere it was measured.

Context from the database reinforces how close these two are to each other and to their respective neighborhoods. The E3-1285L v4's average benchmark score of 1991 places it alongside the AMD Ryzen 5 1500X (1992, delta 0 percent), the Intel Core i7-7920HQ (1992, delta -0.1 percent), the Intel Xeon E3-1585L v5 (1989, delta 0.1 percent), and the Intel Core i5-8279U (1987, delta 0.2 percent). The D-2712T's average of 1964 puts it near the AMD Ryzen 5 2600H (1967, delta -0.1 percent), the AMD Ryzen 3 2300X (1968, delta -0.2 percent), the Intel Core i7-3930K (1960, delta 0.2 percent), and the Intel Core i7-10810U (1971, delta -0.4 percent). Two adjacent performance tiers, roughly 27 points apart on average, with no meaningful separation in any rendering test.

Where Each One Wins

On pure benchmark results, the Xeon E3-1285L v4 wins everywhere, and the D-2712T wins nowhere. That is the honest headline from the head-to-head data. If the decision rested solely on Cinebench scores, the E3-1285L v4 is the pick, full stop: 6 wins from 6 tests, leading by 1 to 1.4 percent in each.

But the data also shows where the D-2712T compensates outside the rendering suite, and those platform attributes define its use case. The D-2712T's memory subsystem is substantially faster on paper: it supports DDR4 on a quad-channel bus with 85.3 GB/s of bandwidth, compared to DDR3 on a dual-channel bus with 29.9 GB/s for the E3-1285L v4. Workloads that stream large data sets through memory, rather than crunching render frames, favor the newer part by a wide margin in raw bandwidth terms.

PCIe is another split. The D-2712T offers PCIe Gen 4 with 32 CPU lanes; the E3-1285L v4 is a Gen 3 part. Storage and networking heavy deployments get a meaningfully newer I/O foundation with the Ice Lake-D chip.

There is one workload category the E3-1285L v4 can serve that the D-2712T cannot: display output. The E3-1285L v4 includes Intel Iris Pro P6300 integrated graphics, while the D-2712T has none. For compact workstations or headless-light builds that still need a GPU without adding a discrete card, the older part is the only option of the two.

Finally, availability matters. The D-2712T is an active product; the E3-1285L v4 is end-of-life, released on 2015-06-01 against the D-2712T's 2022-02-23. Buying the E3-1285L v4 today means buying into an end-of-life platform.

The Verdict

For rendering and general compute as measured by Cinebench, the data says the two are interchangeable, with a marginal edge to the Xeon E3-1285L v4. One percent here or 1.4 percent there will not be visible in real work; both parts deliver sub-1000 Cinebench R23 single-core scores and sit in the 44th percentile of the database. Neither is a performance champion, and neither pretends to be.

Choose the Xeon D-2712T if the deployment depends on platform modernity: DDR4 quad-channel memory with 85.3 GB/s of bandwidth, PCIe Gen 4 with 32 CPU lanes, an active production status, and a newer Ice Lake-D architecture on a 10 nm process. It is the forward-looking choice despite trailing by about one percent in every recorded benchmark.

Choose the Xeon E3-1285L v4 if maximum Cinebench scores on a legacy Socket 1150 platform are the goal, or if integrated graphics are required, since its Iris Pro P6300 is the only display option between the two. Its launch MSRP was $445, compared to $349 for the D-2712T, though the E3-1285L v4's end-of-life status means that figure is historical rather than actionable. Both chips carry the same 65 W TDP and both support ECC memory, so efficiency and data integrity are neutral factors in this pairing.

FAQ

Q: Which CPU is faster in Cinebench? A: The Intel Xeon E3-1285L v4 wins all six recorded benchmarks, leading by 1 percent in Cinebench R15 single-core (97 vs 96) and by 1.4 percent in Cinebench R23 multi-core (6884 vs 6791).

Q: How big is the performance gap between them? A: Very small. Every delta falls between 1 and 1.4 percent, and both chips sit in the 44th percentile versus all CPUs in the database, with average benchmark scores of 1991 for the E3-1285L v4 and 1964 for the D-2712T.

Q: Which CPU has better memory support? A: The Xeon D-2712T, by a wide margin. It supports DDR4 on a quad-channel bus with 85.3 GB/s of bandwidth, while the E3-1285L v4 supports DDR3 on a dual-channel bus with 29.9 GB/s.

Q: Do both CPUs support ECC memory? A: Yes, both the E3-1285L v4 and the D-2712T support ECC memory, consistent with their server and workstation segmentation.

Q: Which CPU has integrated graphics? A: Only the Xeon E3-1285L v4, which includes Intel Iris Pro P6300 graphics. The Xeon D-2712T has no integrated graphics and requires a discrete GPU or headless operation.

Q: Are both CPUs still in production? A: No. The E3-1285L v4 is end-of-life after its 2015-06-01 release, while the D-2712T, released 2022-02-23, is an active product.

Architecture Differences

The two processors bookend an entire architectural era at Intel. The E3-1285L v4 is a Broadwell part, codename Broadwell-DT, built on Intel's 14 nm process with 1,400 million transistors on a 160 mm² die. The D-2712T is an Ice Lake part, codename Ice Lake-D, built on Intel's 10 nm process. Transistor counts and die size are not recorded for the newer chip.

The core topology is identical on paper: 4 cores and 8 threads on both. Where they diverge is clock behavior and cache. The E3-1285L v4 runs a 3.40 GHz base clock with a 3.80 GHz boost; the D-2712T runs a 1.90 GHz base with a 3.00 GHz boost. That frequency advantage is the most plausible explanation for the E3-1285L v4's clean sweep in the Cinebench suite, since the newer architecture cannot fully offset a clock ceiling nearly a gigahertz lower at boost.

Cache tells the opposite story. The D-2712T carries 80 KB of L1 per core and 1.25 MB of L2 per core with 15 MB of shared L3, compared to 64 KB of L1 per core and 256 KB of L2 per core with 6 MB of shared L3 on the E3-1285L v4. The Ice Lake-D part's cache allocation is dramatically larger at every level, which, combined with its memory bandwidth advantage, suggests it was designed for data-throughput workloads rather than frequency-driven rendering throughput.

Platform integration differs accordingly. The E3-1285L v4 uses Intel Socket 1150 with PCIe Gen 3; the D-2712T uses the soldered Intel BGA 2579 package with PCIe Gen 4 and 32 CPU lanes. Neither part has an unlocked multiplier. Both fill the same server and workstation segment, but they arrive at it from opposite directions: the Broadwell chip pushes clocks on an older, cheaper platform, while the Ice Lake-D chip trades frequency for a modern node, deeper caches, quad-channel DDR4, and current-generation I/O, all within the same 65 W envelope.
