CPU Comparison

The Intel Xeon D-1732TE and Intel Xeon E-2186G are both server/workstation processors, but the benchmark data reveals a clear overall winner: the D-1732TE. Across every Cinebench test, the D-1732TE outperforms the E-2186G, despite the E-2186G having significantly higher clock speeds. This makes the D-1732TE the superior choice for compute-heavy workloads, while the E-2186G retains specific advantages in platform compatibility and integrated features.

Head-to-Head Benchmarks

The D-1732TE wins all six head-to-head Cinebench comparisons, with a consistent margin of approximately 4.8% to 4.9% across both multi-core and single-core tests. In Cinebench R23 multi-core, the D-1732TE scores 12052 against the E-2186G's 11492, a 4.9% advantage. The single-core R23 result is similarly decisive, with the D-1732TE scoring 1701 versus 1622, again a 4.9% lead.

This pattern repeats in older Cinebench versions. In R20 multi-core, the D-1732TE scores 5061 versus 4826 (4.9% ahead), and in R20 single-core, it scores 714 versus 681 (4.8% ahead). The R15 results follow the same trend: multi-core 1214 vs 1158 (4.8% lead) and single-core 171 vs 163 (4.9% lead). No test shows the E-2186G winning, and the margin is remarkably uniform, suggesting a consistent architectural efficiency advantage rather than a workload-specific quirk.

It is importantly the E-2186G has additional Geekbench results in its benchmark set (6204 multi-core, 1550 single-core), which the D-1732TE lacks. However, these are not part of the head-to-head comparison, and the Cinebench data fully determines the winner. The D-1732TE's average benchmark score is 3486, slightly above the E-2186G's 3462, further confirming its overall edge.

Where Each One Wins

The D-1732TE wins every benchmark where both are measured. Its victories are not limited to multi-threaded workloads; it also leads in single-core performance. This is notable because the E-2186G has a much higher boost clock (4.70 GHz vs 3.00 GHz), yet still loses in single-threaded tests. The data indicates the D-1732TE's Ice Lake architecture delivers higher instructions per clock, overcoming the clock speed deficit.

The E-2186G's only "wins" are in areas outside raw compute benchmarks. It features integrated graphics (HD Graphics P630), which the D-1732TE lacks entirely. It also uses a standard Socket 1151, which is more common in mainstream motherboards, whereas the D-1732TE uses the proprietary BGA 2227. For systems requiring a discrete GPU, this is irrelevant, but for headless servers or applications needing basic video output, the E-2186G has a functional advantage.

In terms of memory bandwidth, the D-1732TE offers 64.0 GB/s with triple-channel support, while the E-2186G provides 42.7 GB/s with dual-channel support. This 50% bandwidth advantage for the D-1732TE is not directly benchmarked in the provided data, but it likely contributes to its multi-core performance lead. The E-2186G has a larger die size (154 mm²) and a higher TDP (95W vs 52W), but those are power and physical characteristics, not performance wins.

Architecture Differences

The two CPUs come from different Intel generations and process nodes. The D-1732TE is built on Ice Lake-D using a 10 nm process, while the E-2186G uses Coffee Lake-S WS on a 14 nm process. This node advantage explains much of the D-1732TE's efficiency: it delivers higher performance at a much lower 52W TDP compared to the E-2186G's 95W.

Core and thread counts differ significantly. The D-1732TE has 8 cores and 16 threads, while the E-2186G has 6 cores and 12 threads. This gives the D-1732TE a 33% advantage in core count, which directly translates to its multi-core benchmark wins. Cache configurations also differ: the D-1732TE has 80 KB L1 and 1.25 MB L2 per core, with 15 MB shared L3, while the E-2186G has 64 KB L1 and 256 KB L2 per core, with 12 MB shared L3. The D-1732TE's larger per-core L2 cache is particularly significant for data-intensive workloads.

Memory support is another major divergence. Both support DDR4 and ECC, but the D-1732TE uses triple-channel memory with 64.0 GB/s bandwidth, versus the E-2186G's dual-channel 42.7 GB/s. PCIe capabilities also differ: the D-1732TE supports Gen 4 with 16 lanes, while the E-2186G uses Gen 3 with 16 lanes. The D-1732TE has no integrated graphics, while the E-2186G includes HD Graphics P630. Production statuses reflect their generations: the D-1732TE is active, while the E-2186G is end-of-life.

FAQ

Q: Which CPU is faster in multi-core workloads?

A: The D-1732TE wins all multi-core tests. In Cinebench R23 multi-core, it scores 12052 versus 11492 for the E-2186G, a 4.9% lead. Similar margins appear in R20 (5061 vs 4826) and R15 (1214 vs 1158).

Q: Does the E-2186G win in single-core performance due to its higher clock speed?

A: No. Despite a 4.70 GHz boost clock versus 3.00 GHz, the E-2186G loses every single-core test. The D-1732TE scores 1701 vs 1622 in R23 single-core, a 4.9% advantage.

Q: What are the core and thread differences?

A: The D-1732TE has 8 cores and 16 threads. The E-2186G has 6 cores and 12 threads. This gives the D-1732TE more parallel processing capability.

Q: Do both CPUs support ECC memory?

A: Yes, both support ECC memory. However, the D-1732TE uses triple-channel DDR4 with 64.0 GB/s bandwidth, while the E-2186G uses dual-channel DDR4 with 42.7 GB/s.

Q: Which CPU has a smaller manufacturing process?

A: The D-1732TE uses a 10 nm process, while the E-2186G uses 14 nm. The smaller node contributes to the D-1732TE's lower 52W TDP versus 95W.

Q: Does the E-2186G have any unique features?

A: Yes, it includes integrated HD Graphics P630, which the D-1732TE lacks. It also uses Socket 1151, which is more common than the D-1732TE's BGA 2227.

The Verdict

The data is unambiguous: the Intel Xeon D-1732TE is the better processor for raw performance. It wins every benchmark in the head-to-head comparison, with a consistent 4.8-4.9% margin across Cinebench R15, R20, and R23, both single-core and multi-core. Its 8-core/16-thread configuration, larger caches, and triple-channel memory bandwidth give it a structural advantage that clock speed alone cannot overcome.

The E-2186G is not without merit. Its integrated graphics make it a better choice for systems that require basic video output without a discrete GPU. Its Socket 1151 form factor offers broader motherboard compatibility. It also has a lower launch MSRP of $506 compared to the D-1732TE's $730. However, these advantages are peripheral to compute performance.

For server workloads, virtualization, or any application that stresses CPU throughput, the D-1732TE is the clear choice. Its higher performance comes with lower power consumption (52W vs 95W), which is a significant operational benefit. The E-2186G, being end-of-life, also faces a shorter support window. The verdict: pick the D-1732TE for performance and efficiency; pick the E-2186G only if you specifically need integrated graphics or a standard socket.
