Architecture Differences

Both processors are built on Intel's 14 nm process, but they belong to different families. The E-2236 uses the Coffee Lake architecture (codename Coffee Lake-S WS) and is part of the Xeon E-2200 series. The D-1587 uses the Broadwell architecture (codename Broadwell) and is part of the Xeon D line. The E-2236 has 6 cores and 12 threads, while the D-1587 has 16 cores and 32 threads. Clock speeds differ sharply: the E-2236 has a base clock of 3.40 and a boost of 4.80, while the D-1587 has a base clock of 1700.00 and a boost of 2.30.

Cache layouts also differ. Both have 64 KB of L1 and 256 KB of L2 per core, but the E-2236 has 12 MB of shared L3, while the D-1587 has 1.5 MB of L3 per core. The D-1587's die is larger at 246 mm² versus 154 mm², and it lists 3,200 million transistors; the E-2236 has no transistor count in the database.

Memory support: the E-2236 supports DDR4 only, with dual-channel memory and a recorded bandwidth of 42.7 GB/s. The D-1587 supports both DDR3 and DDR4, also dual-channel, but has no listed memory bandwidth. PCIe connectivity is Gen 3 for both, but the D-1587 offers 24 lanes versus 16 for the E-2236. The E-2236 includes UHD Graphics P630, while the D-1587 has no integrated graphics listed.

Socket and power: the E-2236 uses Intel Socket 1151 and has a TDP of 80, while the D-1587 uses Intel BGA 1667 and has a TDP of 65. The E-2236 was released on 2019-05-28 and is end-of-life; the D-1587 was released on 2016-02-23 and remains active.

The Verdict

Benchmark results are clear: the E-2236 wins all six Cinebench tests in the head-to-head comparison. Its margins are 1.8% in five tests and 1.7% in one. The average benchmark score is 3410 for the E-2236 and 3350 for the D-1587. Both processors sit at the 54th percentile, so they are closely matched in overall standing, but the E-2236 is consistently ahead.

Who should pick which? Users who prioritize Cinebench performance should choose the E-2236. It also has a higher boost clock and integrated graphics. The D-1587 offers more cores (16 versus 6), more PCIe lanes (24 versus 16), and a lower TDP (65 versus 80). It also supports DDR3 in addition to DDR4. For workloads that scale with core count or need extra PCIe lanes, the D-1587 may be the better fit, despite its lower Cinebench scores. The D-1587 is also still active in production, while the E-2236 is end-of-life.

Context from the nearest-rival lists: the E-2236's average score of 3410 matches the Xeon E-2146G exactly, and it is 0.1% ahead of the Ryzen Embedded V3C18I and 0.5% ahead of the Ryzen 5 PRO 7530U, while trailing the Core i7-10875H by 0.6%. The D-1587's average of 3350 is 0.5% ahead of the Core i7-7800X and 1.2% ahead of the Core i5-11400T, but 0.5% behind the Ryzen 7 5800U and 1.3% behind the Ryzen 5 PRO 7530U.

Head-to-Head Benchmarks

The head-to-head benchmark table shows a clean sweep for the Intel Xeon E-2236. In Cinebench R15 multi-core, the E-2236 scores 1188 against 1167 for the D-1587, a 1.8% lead. In R15 single-core, the E-2236 scores 167 versus 164, also 1.8% ahead. Cinebench R20 multi-core sees 4952 versus 4865, again 1.8%. R20 single-core is the closest test: 698 versus 686, a 1.7% margin. Cinebench R23 multi-core shows 11792 versus 11585, a 1.8% lead, and R23 single-core has 1664 versus 1635, also 1.8%.

The D-1587's 16 cores and 32 threads do not translate into a multi-core win in these tests. The E-2236's higher clocks, with a boost of 4.80 versus 2.30, appear to be the deciding factor. The average benchmark scores reflect the same pattern: 3410 for the E-2236 and 3350 for the D-1587.

Nearest-rival data reinforces the close competition. The E-2236's average score of 3410 is identical to the Xeon E-2146G, and it is 0.1% ahead of the Ryzen Embedded V3C18I and 0.5% ahead of the Ryzen 5 PRO 7530U, while trailing the Core i7-10875H by 0.6%. The D-1587's average of 3350 is 0.5% ahead of the Core i7-7800X and 1.2% ahead of the Core i5-11400T, but 0.5% behind the Ryzen 7 5800U and 1.3% behind the Ryzen 5 PRO 7530U.
