Architecture Differences

The two processors come from different architectural families, despite both being built on Intel's 14 nm process node. The Intel Xeon D-1567 uses the Broadwell architecture, specifically the Broadwell-DE generation, while the Intel Xeon E-2226G uses the Coffee Lake architecture, from the Coffee Lake-S WS generation. This generational gap matters because Broadwell was designed for dense, low-power server and workstation deployments, while Coffee Lake is a more conventional desktop-derived workstation design.

The transistor counts differ substantially. The Xeon D-1567 packs 3,200 million transistors on a 246 mm² die. The Xeon E-2226G has no listed transistor count but uses a smaller 154 mm² die. The D-1567's larger die accommodates its 12 cores plus the additional uncore logic typical of system-on-chip designs.

Cache layouts differ in structure. Both processors have 64 KB of L1 cache per core and 256 KB of L2 cache per core. However, the L3 cache is organized differently: the D-1567 has 1.5 MB per core, while the E-2226G has 12 MB shared across all cores. This means the D-1567's total L3 cache is substantially larger, though the shared design on the E-2226G can be more efficient for certain workloads that access common data.

Memory support shows another split. The D-1567 supports both DDR3 and DDR4, while the E-2226G supports only DDR4. Both use dual-channel memory buses. The E-2226G has a listed memory bandwidth of 42.7 GB/s; the D-1567 has no listed bandwidth figure. Both support ECC memory.

PCIe lane counts differ: the D-1567 provides 24 Gen 3 lanes from the CPU, while the E-2226G provides 16 Gen 3 lanes. The D-1567 uses the Intel BGA 1667 socket, which is a soldered, embedded form factor. The E-2226G uses Intel Socket 1151, a standard LGA socket that allows for socketed installation.

The integrated graphics situation is one-sided. The E-2226G includes HD Graphics P630, while the D-1567 has no integrated graphics at all. This makes the E-2226G suitable for systems that need display output without a discrete GPU.

Where Each One Wins

The Intel Xeon D-1567 wins in every single benchmark recorded in the head-to-head comparison. It takes all six Cinebench tests, both single-core and multi-core, across R15, R20, and R23. The margins are small but consistent, ranging from 2.2% to 2.3% in every test. This means the D-1567 holds a slight but uniform advantage across all measured workloads.

The multi-core advantage is driven by the core count. With 12 cores and 24 threads versus 6 cores and 6 threads, the D-1567 should theoretically have a much larger lead in heavily threaded workloads. However, the actual benchmark results show only a 2.2% lead in multi-core tests. This suggests the E-2226G's much higher clock speeds (3.40 GHz base, 4.70 GHz boost) are compensating significantly for its lower core count.

The single-core results are more surprising. The D-1567 also wins these, despite having a base clock of 2.10 GHz and a boost clock of 2.70 GHz, far below the E-2226G's clocks. The single-core lead is 2.3% in R15 and R23, and 2.2% in R20. This indicates the Broadwell architecture's per-core efficiency in these specific Cinebench tests is strong enough to overcome the clock deficit.

For workloads that benefit from high clock speeds, the E-2226G's 4.70 GHz boost clock is a clear advantage on paper. The recorded data does not include such tests, but the specification difference is notable. For workloads that benefit from many threads, the D-1567's 24 threads provide headroom beyond what the benchmarks show.

The E-2226G's integrated graphics give it a use case the D-1567 cannot match: systems requiring display output without a separate GPU. The D-1567, with no integrated graphics, requires a discrete graphics solution for any display needs.

• Launch MSRP: 1199 (D-1567) vs $255 (E-2226G)

Head-to-Head Benchmarks

The head-to-head results are decisive in one direction: the Intel Xeon D-1567 wins all six recorded Cinebench tests. The margins are narrow but consistent.

In Cinebench R15 multi-core, the D-1567 scores 965 against the E-2226G's 944, a 2.2% lead. In R15 single-core, the D-1567 scores 136 against 133, a 2.3% lead. The pattern repeats in R20: multi-core shows 4022 versus 3934, a 2.2% lead, and single-core shows 567 versus 555, also 2.2%. In R23, multi-core shows 9578 versus 9368, again 2.2%, and single-core shows 1352 versus 1322, a 2.3% lead.

The consistency of these margins is notable. Every test lands between 2.2% and 2.3% in favor of the D-1567, regardless of whether the test is single-core or multi-core. This uniformity suggests a stable architectural efficiency advantage rather than a workload-specific quirk.

Given the E-2226G's substantial clock speed advantage, one might expect it to win single-core tests. The data shows otherwise. The D-1567's Broadwell architecture delivers higher single-thread performance in Cinebench despite running at much lower clocks. This is a meaningful result for anyone selecting a processor for lightly threaded applications.

The multi-core results also warrant interpretation. With twice the cores and four times the threads, the D-1567 could reasonably be expected to lead by a much larger margin. The fact that it leads by only 2.2% indicates the E-2226G's high clocks are doing heavy lifting in multi-threaded Cinebench workloads, which scale with frequency on this architecture generation.

The nearest rival data puts these scores in context. The D-1567's average benchmark score of 2770 sits between the AMD Ryzen 3 PRO 4350GE (2767, 0.1% ahead) and the AMD Ryzen 3 PRO 4350G (2774, 0.2% behind). The E-2226G's average score of 2709 sits just below the AMD Ryzen 5 PRO 5650U (2713, 0.2% ahead) and just above the Intel Xeon E5-2640 v3 (2703, 0.2% behind). Both processors are clustered closely with their nearest rivals, indicating they occupy a similar performance tier overall.

The Verdict

The data shows a clear winner in raw benchmark performance: the Intel Xeon D-1567 wins every recorded Cinebench test. The margins are small, between 2.2% and 2.3%, but they are uniform across all six tests. If benchmark scores are the primary selection criterion, the D-1567 is the better choice.

The D-1567 also offers substantially more threading resources. Its 12 cores and 24 threads provide headroom for heavily parallel workloads that the E-2226G's 6 cores and 6 threads cannot match. The D-1567's larger die, higher transistor count, and larger per-core L3 cache support this design intent.

The E-2226G is the better choice in specific scenarios. Its 4.70 GHz boost clock is far higher than the D-1567's 2.70 GHz, which matters for applications that are sensitive to raw frequency rather than the specific Cinebench workloads recorded here. Its integrated HD Graphics P630 eliminates the need for a discrete GPU in systems that require display output. Its lower TDP of 80 W versus 65 W is worth noting, though both are modest power envelopes.

The production status is a practical consideration. The D-1567 is listed as Active, while the E-2226G is End-of-life. For long-term deployment planning, the D-1567 has a more favorable availability outlook.

The socket difference is decisive for system design. The D-1567 uses Intel BGA 1667, a soldered embedded form factor. The E-2226G uses Intel Socket 1151, a standard socket that allows processor replacement and upgrade. Systems requiring socketed CPUs should favor the E-2226G, while embedded or dense server designs suit the D-1567.

The launch MSRP figures differ: 1199 for the D-1567 and $255 for the E-2226G. These are launch prices only and reflect the different market positioning of each part.

For buyers prioritizing raw benchmark performance and thread count in a server or workstation context, the Intel Xeon D-1567 is the data-backed choice. For buyers needing integrated graphics, a socketed form factor, or higher clock speeds for frequency-sensitive applications, the Intel Xeon E-2226G is the appropriate selection. The benchmark data records a narrow but consistent victory for the D-1567, while the E-2226G's advantages rest on specifications outside the measured tests.
