Intel Xeon E-2274G vs Intel Xeon E5-4640 v3 Comparison

Intel Xeon E5-4640 v3 and Intel Xeon E-2274G are both end-of-life server/workstation processors, but they solve very different problems. The E5-4640 v3 is a 12-core, 24-thread Haswell-EP part built for a dual-socket-capable platform with massive memory bandwidth, while the E-2274G is a 4-core, 8-thread Coffee Lake part with a very high boost clock for lightly threaded tasks. Benchmark data shows a clean sweep: the E5-4640 v3 wins all six recorded Cinebench head-to-head comparisons, but the margin is narrow, between 6.3% and 6.8% in every test. The real story is not which one is faster overall, but which workload profile matches each chip's design.

Where Each One Wins

The recorded data is unambiguous on test wins. The E5-4640 v3 wins every single head-to-head benchmark in the database: all three Cinebench versions (R15, R20, R23) in both single-core and multi-core runs. That is six wins out of six, with no wins recorded for the E-2274G in any shared test. However, the advantage is consistent but small, always sitting between 6.3% and 6.8%. This means that in raw Cinebench throughput, the older, larger Haswell chip is the faster part across the board.

For multi-core workloads, the E5-4640 v3 leads by 6.3% in Cinebench R15 (888 vs 835), 6.3% in R20 (3702 vs 3481), and 6.4% in R23 (8816 vs 8289). That is a modest but repeatable margin. The E-2274G, despite having only a third of the cores and a third of the threads, manages to stay close because its 4.90 GHz boost clock partly compensates for the core deficit in these particular Cinebench runs.

For single-core workloads, the E5-4640 v3 again wins, with deltas of 6.8% in R15 (125 vs 117), 6.3% in R20 (522 vs 491), and 6.3% in R23 (1244 vs 1170). This is surprising given the E-2274G's much higher clock speed, but the database shows the E5-4640 v3 ahead in every single-threaded test.

The E-2274G does have one recorded benchmark the E5-4640 v3 lacks: Geekbench results. It scores 5174 multi-core and 1586 single-core. These numbers cannot be compared directly to the other chip, but they do place the E-2274G in its own performance envelope for that test suite.

Architecture Differences

The two chips come from different Intel generations and are built for different sockets. The E5-4640 v3 uses the Haswell-EP architecture, codename Haswell-EP, on a 22 nm process, with a die size of 356 mm² and 2,600 million transistors. It fits the Intel Socket 2011-3 platform. The E-2274G uses Coffee Lake, specifically Coffee Lake-S WS, on a 14 nm process, with a 126 mm² die. It fits the Intel Socket 1151 platform. The process node difference is notable: 22 nm versus 14 nm.

Core and thread counts differ sharply. The E5-4640 v3 has 12 cores and 24 threads, while the E-2274G has 4 cores and 8 threads. Cache layouts also differ. Both have 64 KB of L1 per core and 256 KB of L2 per core, but the E5-4640 v3 has 30 MB of shared L3, versus 8 MB on the E-2274G. That is a 22 MB difference in favor of the older chip.

Memory subsystems are built to different scales. The E5-4640 v3 supports DDR4 over a quad-channel bus with 59.7 GB/s of bandwidth. The E-2274G supports DDR4 over a dual-channel bus with 42.7 GB/s. Both support ECC memory, which matters for workstation reliability.

PCIe connectivity also differs. The E5-4640 v3 provides Gen 3 with 40 lanes (CPU only). The E-2274G provides Gen 3 with 16 lanes (CPU only). That is a major platform-level difference for expansion.

The E-2274G includes integrated graphics, specifically HD Graphics P630, while the E5-4640 v3 has no integrated graphics listed. The E-2274G is part of the Xeon E-2200 series, while the E5-4640 v3 has no series designation in the database.

Production status and release timing differ as well. The E5-4640 v3 was released on 2015-05-31, and the E-2274G on 2019-05-28. Both are end-of-life. The E5-4640 v3 has a part number of SR22L, and the E-2274G is SRFDE. Neither chip has an unlocked multiplier.

Head-to-Head Benchmarks

The head-to-head table in the database is short and one-sided. In Cinebench R15 multi-core, the E5-4640 v3 scores 888 against 835, a 6.3% lead. In R15 single-core, it scores 125 against 117, a 6.8% lead. That single-core margin is the largest delta in the entire comparison.

Moving to Cinebench R20, the multi-core result is 3702 for the E5-4640 v3 versus 3481 for the E-2274G, again a 6.3% gap. Single-core R20 shows 522 versus 491, a 6.3% gap. The pattern holds through R23: multi-core is 8816 versus 8289, a 6.4% gap, and single-core is 1244 versus 1170, a 6.3% gap.

Every one of these deltas is within a narrow band, roughly 6.3% to 6.8%. The E5-4640 v3 is consistently ahead, but never by a dramatic amount. For a builder choosing between these two, the benchmark data says the 12-core chip wins every shared test, but the winning margin is not the kind of difference that would transform a workload from unusable to usable.

For context, the E5-4640 v3 sits at the 49th percentile among all CPUs in the database, with an average benchmark score of 2550. Its nearest rivals include the Intel Xeon E5-1650 v3 at 2545 (0.2% ahead of the E5-4640 v3), the AMD Ryzen 7 4800HS at 2557 (0.3% behind), the Intel Core i3-10325 at 2530 (0.8% ahead), and the Intel Xeon E-2244G at 2527 (0.9% ahead). So the E5-4640 v3 is bracketed by a mix of older Xeons, a mobile Ryzen, and a desktop Core i3, all within about one percent.

The E-2274G also sits at the 49th percentile, with an average benchmark score of 2643. Its nearest rivals are the Intel Core i7-5820K at 2642 (0.1% ahead of the E-2274G), the Intel Core i9-8950HK at 2641 (0.1% ahead), the Intel Core i7-7740X at 2648 (0.2% behind), and the Intel Core i7-1195G7 at 2638 (0.2% ahead). All of these rivals are within a fraction of a percent, so the E-2274G is very much in the middle of a tight pack.

The Verdict

The data points to a clear choice based on workload. If the priority is raw Cinebench performance in both single and multi-threaded tests, the Intel Xeon E5-4640 v3 is the better processor. It wins every shared benchmark, with a consistent 6.3% to 6.8% margin. Its 12 cores, 24 threads, 30 MB of L3 cache, quad-channel memory, and 40 PCIe lanes also make it the stronger platform for heavily threaded or expansion-heavy server builds.

The E-2274G is not without its own strengths in the database. It has a much higher base and boost clock (4.00 GHz and 4.90 GHz versus 1.90 GHz and 2.60 GHz), a lower 83 W TDP, a smaller 126 mm² die on a more modern 14 nm process, integrated HD Graphics P630, and a dual-channel memory bus that is simpler to populate. It also carries a lower launch MSRP of $328. But in the recorded head-to-head Cinebench results, it trails in every test.

The average benchmark scores tell a slightly different story. The E-2274G has a higher average benchmark score (2643) than the E5-4640 v3 (2550), but that average includes Geekbench results for the E-2274G that have no counterpart for the E5-4640 v3. In the tests they share, the E5-4640 v3 is consistently ahead.

For a builder choosing between these two end-of-life Xeons, the decision hinges on platform needs. A socket 2011-3 system with quad-channel memory and 40 PCIe lanes favors the E5-4640 v3. A socket 1151 system with integrated graphics and lower power draw favors the E-2274G. On pure benchmark performance in the shared Cinebench suite, the E5-4640 v3 is the winner in all six comparisons.
