Intel Xeon E-2144G vs Intel Xeon E5-4620 v3 Comparison

Head-to-Head Benchmarks

The recorded benchmark data shows a consistent pattern across every single Cinebench test: the Intel Xeon E5-4620 v3 wins all six head-to-head comparisons against the Intel Xeon E-2144G. The victories are not narrow, nor are they isolated to one type of workload. Every delta sits between 13% and 13.4%, which suggests a structural advantage rather than a workload-specific quirk.

In Cinebench R15 multi-core, the E5-4620 v3 scores 901 against 797 for the E-2144G, a 13% lead. The single-core result in the same test is 127 versus 112, a 13.4% margin. Moving to Cinebench R20, the multi-core scores are 3757 and 3322, again a 13.1% difference, while single-core is 530 versus 468, a 13.2% gap. Cinebench R23 repeats the story: 8946 against 7910 in multi-core (13.1%) and 1263 versus 1116 in single-core (13.2%).

What stands out is that the E5-4620 v3 does not merely win on thread-heavy workloads, where its 10 cores and 20 threads would naturally dominate a 4-core, 8-thread part. It also wins every single-core test by a similar margin. That is unusual. The E-2144G has a much higher base clock (3.60 GHz versus 2.00 GHz) and a higher boost clock (4.50 GHz versus 2.60 GHz), yet the older Haswell part still comes out ahead in single-threaded Cinebench runs. The data does not explain why, but the recorded results are unambiguous.

The average benchmark score reinforces the picture. The E5-4620 v3 sits at 2587, while the E-2144G sits at 2514. That is a modest overall gap, but the head-to-head Cinebench deltas are larger. Both processors land at the 49th percentile among all CPUs in the database, meaning they occupy essentially the same position in the overall performance distribution despite their very different architectures and core counts.

Where Each One Wins

The E5-4620 v3 wins every recorded benchmark in this comparison, so the use-case split is not about which processor is faster in a given test. It is about what the margins mean for real workloads.

For multi-threaded rendering, the E5-4620 v3 is the clear pick. A 13% lead in Cinebench R15, R20, and R23 multi-core translates into shorter render times for CPU-based rendering tasks. The 10-core, 20-thread configuration gives it a structural advantage in workloads that scale across cores, and the benchmark results confirm that advantage holds in practice.

For single-threaded tasks, the E5-4620 v3 also wins, but the margin is similar to the multi-core margin, which is surprising given the E-2144G's clock speed advantage. The E-2144G has a 4.50 GHz boost clock, yet it trails by 13.2% to 13.4% in every single-core test. This means the E-2144G is not the better choice for lightly threaded applications based on the recorded data, despite its higher clocks.

The E-2144G does have one clear advantage in the specifications: integrated graphics. It includes HD Graphics P630, while the E5-4620 v3 has no integrated graphics at all. Systems built around the E5-4620 v3 will require a discrete GPU, which is typical for server and workstation platforms but worth noting for anyone expecting a simple single-socket build without extra hardware.

The E-2144G also has a significantly lower TDP at 71 watts versus 105 watts for the E5-4620 v3. That makes it easier to cool and less demanding on power delivery, which matters in compact or power-conscious builds. The E5-4620 v3 is a 2015-era server part with a 105 watt TDP, so it needs a proper server platform and adequate cooling.

Architecture Differences

The two processors come from different Intel generations with different design philosophies. The E5-4620 v3 uses the Haswell-EP architecture on a 22 nm process node. It packs 2,600 million transistors into a 356 mm² die. The E-2144G uses the Coffee Lake architecture on a 14 nm process node, with a much smaller 126 mm² die. The database does not list a transistor count for the E-2144G, so the comparison stops at die size and node.

Core and thread counts differ sharply. The E5-4620 v3 has 10 cores and 20 threads. The E-2144G has 4 cores and 8 threads. Cache configurations follow the same pattern: the E5-4620 v3 has 25 MB of shared L3 cache, while the E-2144G has 8 MB. Both parts use 64 KB of L1 cache per core and 256 KB of L2 cache per core, so the per-core cache hierarchy is identical, but the shared L3 is over three times larger on the E5-4620 v3.

Clock speeds tell the opposite story. The E5-4620 v3 runs at a 2.00 GHz base clock and 2.60 GHz boost clock. The E-2144G runs at 3.60 GHz base and 4.50 GHz boost. That is a 1.60 GHz base clock advantage and a 1.90 GHz boost clock advantage for the E-2144G, yet it still loses every benchmark. The architectural efficiency of the newer Coffee Lake design does not overcome the core count and cache advantage of the older Haswell part in these tests.

Memory support also differs. Both support DDR4 and ECC memory, but the E5-4620 v3 uses a quad-channel memory bus with 59.7 GB/s of bandwidth, while the E-2144G uses a dual-channel bus with 42.7 GB/s. The E5-4620 v3 has more memory bandwidth, which helps in memory-sensitive workloads. PCIe connectivity is another split: the E5-4620 v3 offers 40 PCIe Gen 3 lanes, while the E-2144G offers 16 lanes. That makes the E5-4620 v3 better suited for systems with many expansion cards, NVMe drives, or GPUs.

Sockets are completely different. The E5-4620 v3 uses Intel Socket 2011-3, while the E-2144G uses Intel Socket 1151. These are not interchangeable platforms. The E5-4620 v3 targets the server and workstation market segment, as does the E-2144G, but the physical platforms are incompatible.

Release dates reflect the generational gap. The E5-4620 v3 launched on May 31, 2015. The E-2144G launched on July 11, 2018. Both are now end-of-life products, but the E5-4620 v3 predates the E-2144G by more than three years. The part numbers are SR22K for the E5-4620 v3 and SR3WM for the E-2144G. Neither processor has an unlocked multiplier.

The Verdict

The data points to a straightforward conclusion: the Intel Xeon E5-4620 v3 is the faster processor in every benchmark recorded in this database. It wins all six head-to-head Cinebench tests by a consistent margin of roughly 13%, and its average benchmark score of 2587 is higher than the E-2144G's 2514.

Anyone prioritizing raw CPU performance should choose the E5-4620 v3. It offers more cores, more threads, more L3 cache, quad-channel memory bandwidth, and 40 PCIe lanes. It is the better part for multi-threaded rendering, memory-heavy workloads, and systems that need extensive expansion capability. The fact that it also wins single-core tests, despite the E-2144G's much higher clocks, makes the case even stronger.

The E-2144G is not without its merits. It has a much lower TDP at 71 watts versus 105 watts, which simplifies cooling and power delivery. It includes integrated graphics, so a discrete GPU is not required. Its smaller 126 mm² die and newer 14 nm process node represent a more modern design. But in terms of measured performance, it loses every test.

The choice depends on the platform. If the build already targets Socket 2011-3 or needs the expansion and memory bandwidth of a server platform, the E5-4620 v3 is the obvious pick. If the build targets Socket 1151 and prioritizes low power consumption or integrated graphics, the E-2144G is the only one of the two that fits. On raw benchmark performance alone, the E5-4620 v3 is the winner.

The specification table highlights the fundamental divide between these two parts. The E5-4620 v3 is a high-core-count server processor with a large die, quad-channel memory, and extensive PCIe connectivity. The E-2144G is a lower-power, newer-generation part with higher clocks, integrated graphics, and a much smaller physical footprint. Both support DDR4 and ECC memory, and both are end-of-life products. The benchmark data, however, gives the performance edge to the older, larger, and more expensive E5-4620 v3 across the board.
