Intel Xeon D-1540 vs Intel Xeon E-2244G Comparison

Head-to-Head Benchmarks

The recorded data presents a decisive sweep: the Intel Xeon D-1540 wins all six head-to-head benchmark comparisons against the Intel Xeon E-2244G. The margins are remarkably consistent, hovering around 5% in every test. In Cinebench R15 multi-core, the D-1540 scores 859 against the E-2244G's 818, a 4.8% gap. The single-core result in that same test is nearly identical in percentage terms, with the D-1540 at 121 and the E-2244G at 115, a 5% difference.

Moving to Cinebench R20, the pattern holds. The D-1540 posts 3583 in multi-core versus 3412 for the E-2244G, again a 4.8% delta. Single-core R20 sees the D-1540 at 505 and the E-2244G at 481, also a 4.8% gap. Cinebench R23 follows the same trajectory: the D-1540 reaches 8531 in multi-core, while the E-2244G manages 8126, a 4.7% difference. The R23 single-core test shows the D-1540 at 1204 against 1147 for the E-2244G, another 4.7% margin.

The consistency of these deltas is striking. Across six different workloads, the performance advantage of the D-1540 never deviates outside a narrow band of 4.7% to 5.0%. This suggests a systematic advantage rather than a workload-specific quirk. The E-2244G also has Geekbench scores in the database, with a multi-core result of 4712 and a single-core score of 1408, but no comparable Geekbench data exists for the D-1540 in the head-to-head set.

What does this mean for the overall picture? The average benchmark score for the E-2244G is 2527, placing it at the 49th percentile among all CPUs. The D-1540's average is 2467, at the 48th percentile. Despite the D-1540 winning every direct comparison, the E-2244G actually holds a slightly higher average score across all recorded benchmarks. This is a curious inversion, explained by the fact that the E-2244G's Geekbench numbers (4712 multi-core, 1408 single-core) are included in its average, while the D-1540 has no Geekbench entry to contribute to its average. The head-to-head data, however, is unambiguous: in Cinebench tests, the D-1540 leads across the board.

Architecture Differences

The two processors come from different architectural eras and design philosophies. The Intel Xeon E-2244G belongs to the Xeon E-2200 series, built on Coffee Lake architecture, specifically the Coffee Lake-S WS variant. It uses a 14 nm process node with a die size of 126 mm². The Intel Xeon D-1540 is a Broadwell part, part of the Xeon D family (Broadwell-DE), also on a 14 nm process but with a substantially larger die at 246 mm². The D-1540 contains 3,200 million transistors, a figure not recorded for the E-2244G.

Core counts differ significantly. The E-2244G has 4 cores and 8 threads, while the D-1540 doubles that to 8 cores and 16 threads. Clock speeds tell a different story. The E-2244G runs at a base clock of 3.80 GHz and boosts to 4.80 GHz. The D-1540's base clock is recorded as 2000.00 (likely 2.00 GHz in the database's formatting), with a boost of 2.60 GHz. The E-2244G's far higher clocks explain why it can remain competitive in single-core tests despite the core deficit, but the D-1540's extra cores win out in multi-threaded workloads.

Cache layouts also diverge. Both share the same L1 and L2 sizes per core (64 KB and 256 KB respectively), but L3 differs. The E-2244G has 8 MB of shared L3, while the D-1540 allocates 1.5 MB per core, which across 8 cores totals 12 MB. This per-core allocation favors the D-1540 in multi-threaded scenarios where each core needs its own slice of cache.

Memory support shows another split. The E-2244G supports DDR4 only, with dual-channel memory and a recorded bandwidth of 42.7 GB/s. The D-1540 supports both DDR3 and DDR4, also dual-channel, but its memory bandwidth is not recorded in the database. Both support ECC memory.

PCIe lane counts differ: the E-2244G provides 16 lanes (Gen 3, CPU only), while the D-1540 offers 24 lanes (Gen 3, CPU only). The E-2244G includes integrated graphics (HD Graphics P630), whereas the D-1540 has no integrated graphics. Sockets are entirely different: the E-2244G uses Intel Socket 1151, the D-1540 uses Intel BGA 1667. Production status also differs, with the E-2244G marked as end-of-life and the D-1540 marked as active.

Where Each One Wins

The head-to-head data says the D-1540 wins every Cinebench test, but the nature of those wins matters. In single-core tests, the D-1540's advantage is narrow (around 5%), despite the E-2244G's much higher clock speeds. This is worth investigating. The E-2244G boosts to 4.80 GHz, yet it still trails the D-1540, which boosts to only 2.60 GHz. The data implies the D-1540's architecture extracts more instructions per clock, or the benchmark favors its cache layout, or the E-2244G's thermal and power constraints limit sustained single-core performance. The E-2244G has a TDP of 71 watts, the D-1540 only 45 watts, so power draw is not the limiting factor for the E-2244G.

For multi-core workloads, the D-1540's 8 cores versus 4 cores should produce a larger gap than the observed 4.7% to 4.8%. That the gap is so small suggests the E-2244G's high clocks (3.80 GHz base, 4.80 GHz boost) compensate significantly for fewer cores. Still, the D-1540 wins, meaning applications that scale across all cores will see a consistent, if modest, improvement on the D-1540.

Use-case splits follow from this. The D-1540 suits workloads that are heavily multi-threaded and benefit from more cores and more total L3 cache. Its lower TDP (45 watts) also makes it attractive for dense, power-conscious server deployments, especially given its BGA socket which is typical of embedded or compact systems. The E-2244G, with its integrated graphics, could serve in workstation roles where a discrete GPU is not required, and its higher clocks might benefit lightly threaded tasks that do not saturate all cores. However, the benchmark data shows the D-1540 ahead even in single-core tests, so the E-2244G's clock advantage does not translate into a recorded win anywhere.

The Verdict

The data points to the Intel Xeon D-1540 as the stronger performer in every recorded head-to-head test. Its 8 cores and 16 threads deliver a consistent 4.7% to 5.0% advantage over the E-2244G across all Cinebench R15, R20, and R23 workloads, including single-core. This is notable because the E-2244G has much higher clock speeds (4.80 GHz boost versus 2.60 GHz), yet still loses every time. The D-1540 also offers more PCIe lanes (24 versus 16) and a larger total L3 cache (12 MB versus 8 MB), while consuming less power (45 watts versus 71 watts).

The E-2244G does have advantages in other areas. It includes integrated graphics, which the D-1540 lacks. It has a smaller die (126 mm² versus 246 mm²) and a higher memory bandwidth figure (42.7 GB/s versus no recorded value). Its average benchmark score is slightly higher (2527 versus 2467), though this is influenced by Geekbench results that the D-1540 does not have. The E-2244G is also marked as end-of-life, while the D-1540 is still active.

For a buyer choosing between these two, the D-1540 is the clear choice if raw benchmark performance matters, especially in multi-threaded server workloads. Its active production status and lower power draw add to its appeal. The E-2244G makes sense only if integrated graphics are required or if the higher memory bandwidth figure is critical, since no benchmark win supports its selection. The database's verdict is unambiguous: six wins to zero, all in favor of the Intel Xeon D-1540.
