CPU Comparison

The benchmark data places the Intel Xeon E5-4640 v3 and the Intel Xeon E-2244G in the same performance tier, with average benchmark scores of 2550 and 2527 respectively. The E5-4640 v3 leads by a slim 0.9% margin in this aggregate metric, but the head-to-head results reveal a more complex picture. Across six Cinebench tests, the E5-4640 v3 wins every single matchup, yet the E-2244G counters with a strong Geekbench showing that is not part of the head-to-head set. This is a contest between a 12-core Haswell-EP server chip from 2015 and a 4-core Coffee Lake workstation processor from 2019, and the data shows that core count versus clock speed produces different winners depending on the workload.

Head-to-Head Benchmarks

The E5-4640 v3 dominates the shared Cinebench suite, winning all six tests with a consistent margin. In Cinebench R15 multi-core, the E5-4640 v3 scores 888 against the E-2244G’s 818, a delta of 8.6%. The single-core R15 test shows a similar gap: 125 versus 115, an 8.7% advantage for the older chip. This pattern repeats in Cinebench R20, where the E5-4640 v3 posts 3702 multi-core and 522 single-core, beating the E-2244G’s 3412 and 481 by 8.5% in both tests. The R23 results follow suit, with the E5-4640 v3 scoring 8816 multi-core and 1244 single-core, while the E-2244G manages 8126 and 1147, again an 8.5% edge for the E5-4640 v3.

These margins are uniform, hovering between 8.5% and 8.7% across all six tests. The consistency suggests that the E5-4640 v3’s advantage is structural rather than workload-specific. Despite having three times the cores (12 versus 4) and three times the threads (24 versus 8), the E5-4640 v3 only manages an 8.5-8.6% lead in multi-core tests. This is a surprisingly small gap for such a large core-count difference, and it points to the E-2244G’s much higher clock speeds compensating for its lower core count. The E-2244G runs at a base clock of 3.80 GHz and boosts to 4.80 GHz, while the E5-4640 v3 sits at 1.90 GHz base and 2.60 GHz boost.

The E-2244G does have one benchmark that the E5-4640 v3 lacks: Geekbench. In Geekbench multi-core, the E-2244G scores 4712, and in single-core it reaches 1408. These scores are not directly comparable to the Cinebench results, but they indicate that the E-2244G is capable of strong performance in a different rendering workload. Since the head-to-head table only lists six Cinebench tests, the E-2244G’s Geekbench scores are its only counterpoints, and they cannot be used to claim a win over the E5-4640 v3 without a direct comparison.

Architecture Differences

The two processors come from different eras and use fundamentally different designs. The E5-4640 v3 is built on the Haswell-EP architecture using a 22 nm process node from Intel, with a die size of 356 mm² and 2,600 million transistors. The E-2244G uses the Coffee Lake architecture on a 14 nm process, with a much smaller die size of 126 mm² and no transistor count listed in the data. The E5-4640 v3 is a large, power-hungry server chip designed for multi-socket systems, while the E-2244G is a smaller workstation part.

Memory support differs substantially. The E5-4640 v3 supports DDR4 memory over a quad-channel bus, delivering 59.7 GB/s of bandwidth. The E-2244G also supports DDR4 but only over a dual-channel bus, capping bandwidth at 42.7 GB/s. This 17 GB/s difference in theoretical memory bandwidth favors the E5-4640 v3, which is relevant for memory-intensive server workloads. Both processors support ECC memory, which is expected for the server/workstation market segment.

The cache layouts reflect the core-count disparity. The E5-4640 v3 has 64 KB of L1 cache per core, 256 KB of L2 per core, and 30 MB of shared L3 cache. The E-2244G has the same per-core L1 and L2 sizes but only 8 MB of shared L3. The E5-4640 v3’s 30 MB L3 is 3.75 times larger, matching its higher core count. PCIe connectivity also differs: the E5-4640 v3 provides Gen 3 with 40 lanes from the CPU, while the E-2244G offers Gen 3 with 16 lanes. The E5-4640 v3 is clearly aimed at systems needing more expansion and memory bandwidth.

The E-2244G has an integrated GPU (HD Graphics P630), while the E5-4640 v3 has none listed. This is a notable feature difference, as the E-2244G can drive a display without a discrete graphics card. The E5-4640 v3 requires a separate GPU, which is typical for server processors. Both chips have locked multipliers, and neither is unlocked for overclocking.

The Verdict

The data shows a clear split between the two processors. The E5-4640 v3 wins every Cinebench benchmark, both multi-core and single-core, with margins of 8.5-8.7%. It also offers higher memory bandwidth (59.7 GB/s versus 42.7 GB/s), more PCIe lanes (40 versus 16), and a much larger L3 cache (30 MB versus 8 MB). For workloads that rely on the Cinebench rendering engine, the E5-4640 v3 is the better choice.

The E-2244G, however, has its own advantages. It has a significantly higher boost clock (4.80 GHz versus 2.60 GHz), a lower TDP (71 W versus 105 W), a smaller die (126 mm² versus 356 mm²), and an integrated GPU. Its Geekbench scores of 4712 multi-core and 1408 single-core show that it can perform well in other types of benchmarks, even if those are not directly comparable to Cinebench results. The E-2244G also supports dual-channel memory, which is sufficient for many workstation tasks.

The average benchmark scores place both chips at the 49th percentile of all CPUs, meaning they are statistically average performers. The E5-4640 v3’s nearest rival is the Intel Xeon E5-1650 v3, which scores 2545 (a 0.2% delta), while the E-2244G’s closest competitor is the Intel Core i3-10325 at 2530 (a -0.1% delta). These rival comparisons reinforce that both chips sit in a tight performance cluster.

Where Each One Wins

The E5-4640 v3 wins in all six shared Cinebench tests, covering R15, R20, and R23 in both multi-core and single-core modes. Its largest margin is 8.7% in Cinebench R15 single-core, and its smallest is 8.5% in several others. This makes it the stronger choice for CPU rendering workloads that use the Cinebench engine. The E5-4640 v3 also wins on memory bandwidth (59.7 GB/s versus 42.7 GB/s), PCIe lanes (40 versus 16), and L3 cache size (30 MB versus 8 MB). These advantages favor memory-heavy and multi-threaded server applications.

The E-2244G wins on power efficiency, with a TDP of 71 W compared to the E5-4640 v3’s 105 W. It also has a much higher boost clock (4.80 GHz versus 2.60 GHz), which could benefit lightly threaded tasks that are not captured in the Cinebench suite. The E-2244G’s Geekbench scores of 4712 multi-core and 1408 single-core indicate it has competitive performance in that benchmark, although no direct head-to-head comparison exists. Its integrated GPU provides a display output option that the E5-4640 v3 lacks. The E-2244G also has a smaller die (126 mm² versus 356 mm²), which may indicate lower manufacturing complexity.

Specification Differences

The two processors differ across nearly every specification. The E5-4640 v3 uses the Haswell-EP architecture on a 22 nm process with 2,600 million transistors and a 356 mm² die. The E-2244G uses Coffee Lake on a 14 nm process with a 126 mm² die and no listed transistor count. The E5-4640 v3 has 12 cores and 24 threads, while the E-2244G has 4 cores and 8 threads.
