Intel Xeon D-1577 vs Intel Xeon E-2274G Comparison

The Intel Xeon E-2274G and Intel Xeon D-1577 represent two very different approaches to server processing within Intel's Xeon lineup. The E-2274G is a high-clock, quad-core workstation part built on the Coffee Lake architecture, while the D-1577 is a dense, 16-core system-on-chip designed for low-power, high-throughput environments on the Broadwell architecture. The benchmark data shows a clear overall winner in the D-1577, which takes all six head-to-head tests, but the nature of those wins and the architectural trade-offs tell a more nuanced story.

FAQ

Architecture Differences

The two processors diverge sharply in their fundamental design goals. The Intel Xeon E-2274G is built on the Coffee Lake architecture, specifically the Coffee Lake-S WS variant, and uses a 14 nm process node from Intel. Its die size is 126 mm². The Intel Xeon D-1577 is based on the Broadwell architecture, specifically Broadwell-DE, also on a 14 nm process, but with a substantially larger die at 246 mm² and 3,200 million transistors.

Core configuration is the most obvious split. The E-2274G offers 4 cores and 8 threads, while the D-1577 offers 16 cores and 32 threads. This fourfold increase in core count is the primary driver of the D-1577's multi-core performance advantage. Clock speeds tell the opposite story: the E-2274G has a base clock of 4.00 GHz and a boost clock of 4.90 GHz, while the D-1577 has a base clock of 1300.00 MHz (1.30 GHz) and a boost clock of 2.10 GHz. The E-2274G's much higher clocks are its main asset, though the data shows they are not enough to overcome the D-1577's core advantage in these benchmarks.

Cache hierarchies also differ. Both have 64 KB of L1 and 256 KB of L2 per core. The L3 cache, however, is organized differently: the E-2274G has 8 MB shared, while the D-1577 has 1.5 MB per core. Memory support is another differentiator: the E-2274G supports DDR4 only, while the D-1577 supports both DDR3 and DDR4. Both use a dual-channel memory bus, and both support ECC memory. The E-2274G has a memory bandwidth of 42.7 GB/s, while the D-1577's memory bandwidth is not recorded in the database.

Socket and platform requirements are entirely different. The E-2274G uses Intel Socket 1151, while the D-1577 uses Intel BGA 1667, a soldered, embedded form factor. PCIe lane counts also differ: the E-2274G provides Gen 3, 16 lanes (CPU only), while the D-1577 provides Gen 3, 24 lanes (CPU only). The E-2274G includes integrated HD Graphics P630, whereas the D-1577 has no integrated graphics. Production status also differs: the E-2274G is end-of-life, while the D-1577 is active.

Head-to-Head Benchmarks

The recorded benchmark data shows a consistent pattern: the Intel Xeon D-1577 outperforms the Intel Xeon E-2274G across every test in the head-to-head comparison. The margin is remarkably uniform, hovering around 11.7% to 12% in favor of the D-1577.

In Cinebench R15 multi-core, the D-1577 scores 946 against the E-2274G's 835, a delta of -11.7% for the E-2274G. The single-core R15 test shows a slightly larger gap: the D-1577 scores 133, the E-2274G scores 117, a -12% delta. This is notable because single-core performance is typically where high-clock parts like the E-2274G should excel. The D-1577's lower clock speed does not prevent it from taking the win here.

Moving to Cinebench R20, the pattern holds. Multi-core results show the D-1577 at 3943 versus the E-2274G at 3481, again a -11.7% delta. Single-core R20 shows the D-1577 at 556 and the E-2274G at 491, a -11.7% delta. The consistency of the margin across different Cinebench versions suggests a stable performance relationship between the two parts.

Cinebench R23 confirms the trend. Multi-core scores are 9389 for the D-1577 and 8289 for the E-2274G, a -11.7% delta. Single-core scores are 1325 for the D-1577 and 1170 for the E-2274G, also -11.7%. The D-1577's wins are not narrow or workload-specific; they are broad and consistent.

The average benchmark score in the database reinforces this. The D-1577 has an average benchmark score of 2715, while the E-2274G has 2643. The D-1577 also sits at the 50th percentile among all CPUs, compared to the E-2274G's 49th percentile. The D-1577's nearest rivals include the Intel Core i7-11390H with a delta of 0%, and the AMD Ryzen 5 PRO 5650U with a delta of 0.1%. The E-2274G's nearest rivals include the Intel Core i7-5820K with a delta of 0.1% and the Intel Core i9-8950HK with a delta of 0.1%.

The Verdict

The data points to a clear winner: the Intel Xeon D-1577. It wins all six head-to-head benchmarks, holds a higher average benchmark score (2715 vs 2643), and achieves this while consuming less power, with a TDP of 45 watts versus 83 watts. For workloads that rely on Cinebench-style rendering and multi-threaded throughput, the D-1577 is the superior choice. Its 16 cores and 32 threads provide a decisive advantage that the E-2274G's higher clock speeds cannot offset.

The E-2274G is not without its merits, but the recorded data does not favor it in any benchmark. Its strengths lie in its architecture: a 4.90 GHz boost clock, integrated HD Graphics P630, and a smaller 126 mm² die. It also uses the more common Intel Socket 1151, which may offer broader platform compatibility. However, for pure compute performance as measured in this database, the E-2274G trails the D-1577 by roughly 12% in every test.

The D-1577 is the pick for users prioritizing core count, multi-threaded performance, and power efficiency. The E-2274G may still appeal to those who need integrated graphics or prefer a socketed, upgradeable platform, but the benchmark results show it is the slower part in this comparison. The D-1577's active production status and higher percentile ranking further solidify its position.
