Intel Xeon E-2244G vs Intel Xeon E5-4620 v3 Comparison

The Verdict

The recorded benchmark data tells a clear story: the Intel Xeon E5-4620 v3 wins all six head-to-head comparisons against the Intel Xeon E-2244G. The older Haswell-based processor takes the multicore tests with scores between 10.1% and 10.1% higher, and it also leads in every single-core test by margins of 10.1% to 10.4%. The E5-4620 v3 posts a Cinebench R23 multicore score of 8946 versus 8126 for the E-2244G, and a single-core score of 1263 versus 1147. Neither chip reaches above the 49th percentile among all CPUs in the database, so both sit in the middle of the performance distribution, but the E5-4620 v3 is consistently the stronger choice for compute workloads.

The E-2244G has its own advantages, but they do not show up in these particular benchmarks. It carries a much lower TDP of 71 watts against 105 watts, it includes integrated graphics (HD Graphics P630), and it fits into the more common Socket 1151 platform. The E5-4620 v3 requires Socket 2011-3 and has no integrated graphics. For a system builder who needs a simple single-socket workstation with onboard display output, the E-2244G is the practical pick. For raw processing throughput, the data points squarely to the E5-4620 v3.

Architecture Differences

The two processors come from different eras and different design philosophies. The E5-4620 v3 uses the Haswell-EP microarchitecture on a 22 nm process node, with a die size of 356 mm² and 2,600 million transistors. It is a 10-core, 20-thread part with a base clock of 2000 MHz and a boost clock of 2600 MHz. Its shared L3 cache is 25 MB, and each core has 64 KB of L1 and 256 KB of L2 cache. The chip supports DDR4 memory over a quad-channel bus, delivering 59.7 GB/s of memory bandwidth. It provides 40 PCIe Gen 3 lanes from the CPU.

The E-2244G is a Coffee Lake-S WS design on the newer 14 nm process, with a die size of 126 mm² and no recorded transistor count. It has 4 cores and 8 threads, with a base clock of 3800 MHz and a boost clock of 4800 MHz. The L3 cache is 8 MB shared, while L1 and L2 remain the same per-core sizes at 64 KB and 256 KB. Memory support is DDR4 over a dual-channel bus, giving 42.7 GB/s of bandwidth. The CPU provides 16 PCIe Gen 3 lanes and includes HD Graphics P630.

The architectural gap explains the benchmark outcomes. The E5-4620 v3 has 6 more cores and 12 more threads, plus more than three times the L3 cache and roughly 40% more memory bandwidth. The E-2244G counters with much higher clock speeds, 3.80 GHz base and 4.80 GHz boost, but the E5-4620 v3 still manages to win the single-core tests. That is a notable result: the older chip's single-core scores of 127 in Cinebench R15, 530 in R20, and 1263 in R23 all exceed the E-2244G's 115, 481, and 1147 respectively. The E-2244G's clock advantage does not translate into a win in these recorded workloads.

Head-to-Head Benchmarks

The head-to-head table lists six benchmark comparisons, and the E5-4620 v3 wins all of them. The multicore margins are remarkably consistent: 10.1% in Cinebench R15, 10.1% in R20, and 10.1% in R23. The specific scores are 901 versus 818 in R15 multicore, 3757 versus 3412 in R20 multicore, and 8946 versus 8126 in R23 multicore. These are not close calls; the E5-4620 v3 holds a steady advantage of roughly one-tenth across all three rendering tests.

The single-core results follow the same pattern but with slightly larger deltas. In Cinebench R15 single-core, the E5-4620 v3 scores 127 against 115, a 10.4% lead. In R20 single-core, it scores 530 against 481, a 10.2% lead. In R23 single-core, it scores 1263 against 1147, a 10.1% lead. The consistency of these margins suggests a structural advantage rather than a workload-specific artifact. The E5-4620 v3's larger cache and memory subsystem appear to compensate for its lower clock speeds, even in lightly threaded tests.

The E-2244G does appear in the database with additional Geekbench scores: 4712 multicore and 1408 single-core. The E5-4620 v3 has no recorded Geekbench results, so those two data points cannot be compared directly. In the six tests where both chips have results, the E5-4620 v3 is unbeaten.

Where Each One Wins

The E5-4620 v3 wins every recorded benchmark in the head-to-head comparison. Its strongest areas are multithreaded rendering workloads: it leads by 10.1% in Cinebench R15, R20, and R23 multicore tests. The scores of 901, 3757, and 8946 are all higher than the E-2244G's corresponding 818, 3412, and 8126. The E5-4620 v3 also wins all three single-core tests, with margins between 10.1% and 10.4%. That makes it the better choice for any workload represented by these Cinebench tests, whether fully threaded or lightly threaded.

The E-2244G has no benchmark wins in this comparison, but it holds advantages that matter outside of raw compute scores. Its 71 watt TDP makes it far more power-efficient on paper, which can reduce cooling requirements and operating costs in dense server deployments. The integrated HD Graphics P630 provides display output without a discrete GPU, which is useful for headless servers that still need a console or for basic workstation tasks. Its Socket 1151 platform is widely used and typically offers cheaper motherboards and more flexible system configurations than the Socket 2011-3 platform required by the E5-4620 v3. The E-2244G also has a higher base clock of 3.80 GHz and boost clock of 4.80 GHz, which could benefit latency-sensitive workloads that are not captured in these Cinebench tests.

For users who prioritize throughput per socket, the E5-4620 v3 is the data-backed winner. For users who prioritize low power, integrated graphics, or platform simplicity, the E-2244G has qualitative advantages that the benchmarks do not measure.

Specification Differences

The two CPUs differ on every major specification except for the per-core L1 and L2 cache sizes, both of which are 64 KB and 256 KB per core respectively. The E5-4620 v3 is a 10-core, 20-thread part with a base clock of 2000 MHz and a boost clock of 2.60 GHz, while the E-2244G is a 4-core, 8-thread part with a base clock of 3800 MHz and a boost clock of 4.80 GHz. The E5-4620 v3 uses the Haswell architecture on a 22 nm process with a 356 mm² die and 2,600 million transistors; the E-2244G uses Coffee Lake on a 14 nm process with a 126 mm² die and no recorded transistor count.

The L3 cache differs substantially: 25 MB shared on the E5-4620 v3 versus 8 MB shared on the E-2244G. Memory support is DDR4 for both, but the E5-4620 v3 uses a quad-channel bus with 59.7 GB/s bandwidth, while the E-2244G uses a dual-channel bus with 42.7 GB/s. PCIe lane counts also differ: the E5-4620 v3 provides 40 Gen 3 lanes, while the E-2244G provides 16 Gen 3 lanes. The E5-4620 v3 has no integrated graphics, while the E-2244G includes HD Graphics P630. The TDP ratings are 105 watts for the E5-4620 v3 and 71 watts for the E-2244G. The sockets are different as well: Socket 2011-3 for the E5-4620 v3 and Socket 1151 for the E-2244G. Both processors support ECC memory, and neither has an unlocked multiplier.
