Where Each One Wins

The benchmark data delivers a clear verdict: the Intel Xeon E5-4620 v3 wins every recorded test in the head-to-head comparison. Across all six benchmarks, the E5-4620 v3 leads by margins between 7.3% and 7.9%. This is a complete sweep, with the older Haswell-EP part outperforming the newer Coffee Lake chip in both single-core and multi-core workloads.

The Intel Xeon E-2274G, despite its higher base and boost clocks, does not post a single winning score in the direct comparison. Its 4-core, 8-thread configuration limits its multi-core throughput, and even in single-core tests, the E5-4620 v3 comes out ahead. The recorded data shows the E5-4620 v3 wins the Cinebench R15, R20, and R23 single-core tests by roughly 7.4% to 7.9%.

For workloads that rely on raw multi-threaded performance, the E5-4620 v3's 10 cores and 20 threads provide a substantial advantage. The E-2274G, with its higher clock speeds, would appear better suited for lightly threaded tasks, but the benchmarks do not support that conclusion. The E5-4620 v3 dominates in every measured category, making it the stronger choice for both single-core and multi-core intensive applications.

Architecture Differences

The two processors come from different architectural generations and design philosophies. The Intel Xeon E-2274G uses the Coffee Lake architecture, specifically the Coffee Lake-S WS codename, built on a 14 nm process. The Intel Xeon E5-4620 v3 uses the Haswell architecture, codenamed Haswell-EP, built on a 22 nm process. The die sizes reflect the gap: the E-2274G has a die size of 126 mm², while the E5-4620 v3 has a die size of 356 mm² and contains 2,600 million transistors.

The cache hierarchy differs notably. Both processors have 64 KB of L1 cache per core and 256 KB of L2 cache per core. The L3 cache, however, is significantly larger on the E5-4620 v3, with 25 MB shared across all cores, compared to 8 MB shared on the E-2274G. This larger cache is likely a factor in the E5-4620 v3's consistent performance lead.

Memory architecture also separates the two. The E-2274G uses a dual-channel memory bus, while the E5-4620 v3 uses a quad-channel bus. This contributes to the E5-4620 v3's higher memory bandwidth of 59.7 GB/s versus 42.7 GB/s. Both support DDR4 memory and ECC, but the E5-4620 v3 offers more memory channels for server workloads.

The PCIe configurations differ as well. The E-2274G provides Gen 3 with 16 lanes from the CPU, while the E5-4620 v3 provides Gen 3 with 40 lanes. This makes the E5-4620 v3 more suitable for systems with multiple expansion cards or high-bandwidth devices.

Another key difference is integrated graphics. The E-2274G includes HD Graphics P630, whereas the E5-4620 v3 has no integrated graphics at all. This means the E-2274G can drive a display without a discrete GPU, while the E5-4620 v3 requires a separate graphics card.

Specification Differences

The core and thread counts are the most obvious difference: 4 cores and 8 threads for the E-2274G, versus 10 cores and 20 threads for the E5-4620 v3. Clock speeds also differ substantially. The E-2274G has a base clock of 4.00 GHz and a boost clock of 4.90 GHz. The E5-4620 v3 has a base clock of 2000.00 MHz and a boost clock of 2.60 GHz.

Thermal design power differs as well. The E-2274G has a TDP of 83 watts, while the E5-4620 v3 has a TDP of 105 watts. The E-2274G fits into the Intel Socket 1151, while the E5-4620 v3 uses the Intel Socket 2011-3.

The L3 cache is another differentiating factor: 8 MB shared on the E-2274G versus 25 MB shared on the E5-4620 v3. Memory bandwidth favors the E5-4620 v3, with 59.7 GB/s compared to 42.7 GB/s for the E-2274G. PCIe lanes also differ, with 16 lanes on the E-2274G and 40 lanes on the E5-4620 v3.

The E-2274G includes integrated graphics, while the E5-4620 v3 does not. The process nodes differ, with 14 nm for the E-2274G and 22 nm for the E5-4620 v3. The E5-4620 v3 has a much larger die at 356 mm² and 2,600 million transistors, while the E-2274G has a die of 126 mm² with no transistor count listed. The release dates also differ, with the E-2274G launching on May 28, 2019, and the E5-4620 v3 launching on May 31, 2015.

Head-to-Head Benchmarks

The direct comparison shows a consistent pattern: the Intel Xeon E5-4620 v3 wins all six tests. In Cinebench R15 multi-core, the E5-4620 v3 scores 901 against 835 for the E-2274G, a delta of -7.3% for the E-2274G. In Cinebench R15 single-core, the E5-4620 v3 scores 127 against 117, a delta of -7.9%.

Cinebench R20 results follow the same trend. In multi-core, the E5-4620 v3 scores 3757 versus 3481 for the E-2274G, a delta of -7.3%. In single-core, the E5-4620 v3 scores 530 versus 491, a delta of -7.4%.

Cinebench R23 shows similar margins. The E5-4620 v3 scores 8946 in multi-core versus 8289 for the E-2274G, a delta of -7.3%. In single-core, the E5-4620 v3 scores 1263 versus 1170, a delta of -7.4%.

The largest margin is in Cinebench R15 single-core, where the E5-4620 v3 leads by 7.9%. The smallest margins are 7.3%, which appear in Cinebench R15 multi-core, R20 multi-core, and R23 multi-core. The consistency of these results is notable: across different benchmark versions and workload types, the performance gap remains tightly clustered between 7.3% and 7.9%.

The E-2274G also has Geekbench scores in the database, with 5174 in multi-core and 1586 in single-core, but no direct Geekbench comparison is recorded for the E5-4620 v3. The E-2274G's average benchmark score is 2643, while the E5-4620 v3's average benchmark score is 2587. Both processors sit at the 49th percentile among all CPUs.

The Verdict

The data points to a clear winner: the Intel Xeon E5-4620 v3 outperforms the Intel Xeon E-2274G in every recorded head-to-head benchmark. The E5-4620 v3's 10 cores and 20 threads deliver superior multi-core performance, while its single-core results also exceed those of the E-2274G by a consistent margin. For workloads that depend on Cinebench-style rendering or similar CPU-bound tasks, the E5-4620 v3 is the better choice.

The E-2274G is not without its advantages, though the benchmarks do not reflect them. It has a much higher base clock of 4.00 GHz and boost clock of 4.90 GHz, a lower TDP of 83 watts, and integrated graphics. It also fits into the more common Intel Socket 1151 and uses a newer 14 nm process. These features could matter for systems where power consumption, integrated graphics, or socket compatibility are priorities.

However, the recorded performance data is unambiguous. The E5-4620 v3 wins all six Cinebench tests, with deltas ranging from 7.3% to 7.9%. The E-2274G has no wins in the head-to-head comparison. Users who need maximum CPU performance from these two options should choose the E5-4620 v3. Users who need integrated graphics, a lower TDP, or a smaller socket footprint may prefer the E-2274G, but they should be prepared for lower benchmark scores across the board.

The E5-4620 v3 also offers more memory bandwidth at 59.7 GB/s versus 42.7 GB/s, a larger 25 MB L3 cache versus 8 MB, and 40 PCIe lanes versus 16. These specifications reinforce its position as the stronger performer for server and workstation workloads. The E-2274G, with its higher clocks and newer process, represents a more modern design, but the older Haswell chip simply delivers better measured results. The verdict from the database is clear: the Intel Xeon E5-4620 v3 is the superior processor in this comparison.
