Intel Xeon D-1577

The Intel Xeon D-1577 is a 16-core, 32-thread server/workstation processor in the Xeon D (Broadwell-DE) generation, released on 2016-02-23 with a launch MSRP of 1379. Its aggregate average benchmark score is 2,863, placing it at the 54th percentile of all CPUs. The supplied data set covers Cinebench R15, R20, and R23 results, platform specifications, nearest-rival comparisons, and thermal characteristics.

Benchmark Performance

Across the supplied Cinebench runs, the D-1577’s multi-core results are consistently far above its single-core results. In Cinebench R15, it posts 997 multi-core and 140 single-core. In R20, the multi-core score is 4,157 and the single-core score is 586. In R23, the multi-core score reaches 9,898, while the single-core score is 1,397. This pattern is characteristic of a part built around parallel throughput: the 16-core, 32-thread layout produces strong heavy-thread workloads, while the single-core scores remain modest by comparison.

The average benchmark score of 2,863 places the D-1577 at the 54th percentile versus all CPUs, which is just above the midpoint of the database. The nearest rivals occupy a very tight cluster around this aggregate figure. The AMD Ryzen 3 PRO 5475U averages 2,865, leaving the Xeon 0.1% behind. The Intel Core i7-11370H averages 2,882, a 0.6% advantage over the Xeon. The Intel Core i3-13100TE averages 2,887, a 0.8% advantage. The Intel Core i7-6800K averages 2,843, and the Xeon sits 0.7% ahead. These deltas are small, meaning the D-1577 belongs to a densely packed performance tier rather than standing out clearly from any one direct competitor.

Platform and Compatibility

Architecturally, the D-1577 is a Broadwell part from the Xeon D (Broadwell-DE) generation, built on Intel’s 14 nm process at Intel’s own foundry. The die contains 3,200 million transistors and measures 246 mm². The socket is Intel BGA 1667, and the production status is Active. The part number is SR2M2.

Memory support includes both DDR3 and DDR4, running on a dual-channel memory bus. ECC memory is supported, which aligns with the processor’s server/workstation positioning. The CPU provides PCIe Gen 3 with 24 lanes from the CPU. Integrated graphics are not listed, so display output requires either a discrete graphics solution or a headless configuration. The multiplier is locked, and the market segment is Server/Workstation.

Because the socket is BGA 1667, the processor is tied to the board at integration level. The upgrade path is therefore a platform-level consideration: any change in CPU capability would involve the board and socket combination rather than a simple socketed drop-in replacement. The release date of 2016-02-23 and the Active production status together indicate a long-lived embedded/server part rather than a recent consumer desktop release.

How It Compares

AMD Ryzen 3 PRO 5475U: The Ryzen 3 PRO 5475U has an average score of 2,865, which is 0.1% higher than the D-1577. The two are effectively at parity in the aggregate benchmark data.

Intel Core i7-11370H: The Core i7-11370H averages 2,882, putting it 0.6% ahead of the D-1577. The gap is narrow, but the Xeon does not close it in the supplied data.

Intel Core i7-6800K: The Core i7-6800K averages 2,843. The D-1577 leads this rival by 0.7%, making the i7-6800K the only nearest rival the Xeon outperforms in aggregate score.

Intel Core i3-13100TE: The Core i3-13100TE averages 2,887, which is 0.8% ahead of the D-1577. This is the largest deficit in the rival group, though still a small overall margin.

FAQ

Q: What is the average benchmark score of the Intel Xeon D-1577?

A: The average benchmark score is 2,863, and it ranks at the 54th percentile versus all CPUs.

Q: How many cores and threads does the D-1577 have?

A: It has 16 cores and 32 threads.

A: It supports DDR3 and DDR4 memory in dual-channel mode with ECC support, and it provides PCIe Gen 3 with 24 lanes from the CPU.

Q: Does the D-1577 include integrated graphics?

A: No integrated graphics are listed, so the processor does not carry an iGPU in the supplied specification.

Q: Is the multiplier unlocked?

A: No, the multiplier is locked.

Power and Thermals

The D-1577 has a TDP of 45 W, a low power envelope for a 16-core, 32-thread server/workstation processor. The base clock is 1.30 GHz, and the boost clock is 2.10 GHz, so the 45 W thermal budget covers the full working frequency range. The 14 nm process and 45 W TDP together point to a modest active cooling solution being sufficient; the data does not indicate a need for exotic cooling. Since the integrated graphics field is null, there is no on-die GPU heat source contributing to the thermal load. The combination of a 45 W TDP and BGA packaging is consistent with a thermally efficient board-level server processor.

Who Should Consider It

Organizations running heavily threaded server workloads should consider the D-1577 if they need 16 cores and 32 threads in a low-power platform. The Cinebench R23 multi-core score of 9,898 is the strongest multi-core result in the supplied data, and the R20 and R15 multi-core scores of 4,157 and 997, respectively, reinforce the parallel throughput profile. ECC memory support makes the part a plausible fit for memory-integrity-conscious server roles.

Creation workloads that scale well across many threads are also a reasonable target. The multi-core Cinebench results indicate that rendering or batch processing tasks that can use 32 threads would benefit more than tasks that depend on one or two strong cores. For ordinary office or lightly threaded productivity, the single-core scores of 1,397 in R23, 586 in R20, and 140 in R15 define a modest per-thread ceiling; the processor will handle such tasks, but it is not a single-core leader.

Gaming is not a primary use case from the supplied data. There is no integrated graphics, so a discrete GPU is mandatory, and the server/workstation market segment plus modest single-core scores point away from gaming-first use. The 24 PCIe Gen 3 lanes are available to carry a discrete adapter, but the processor’s benchmark profile is weighted toward multi-core throughput.

System builders who choose the D-1577 should plan around the Intel BGA 1667 socket and accept that the CPU is a board-level component. The 45 W TDP, 16-core parallel capability, ECC memory support, and Active production status make it a candidate for dense, reliable, multi-threaded server environments rather than for socket-level upgrades or high-frequency consumer builds.
