CPU Comparison

The Intel Xeon E-2244G and Intel Xeon E5-2630 v3 are both end-of-life server/workstation processors from Intel, but they represent starkly different design philosophies. The E-2244G is a modern, high-clock 4-core part built on the 14 nm Coffee Lake architecture, while the E5-2630 v3 is an older 8-core Haswell-EP part on the 22 nm node. The benchmark data shows a remarkably consistent pattern: the E5-2630 v3 wins every single head-to-head test, albeit by a narrow margin. Despite the E-2244G's significant clock speed advantage, the older chip's extra cores and larger cache pool give it a persistent edge across all Cinebench workloads.

Head-to-Head Benchmarks

The head-to-head results are unambiguous: the Intel Xeon E5-2630 v3 wins all six recorded comparisons, with the E-2244G trailing by a nearly identical percentage in every test. In Cinebench R15 multi-core, the E5-2630 v3 scores 873 against the E-2244G's 818, a delta of -6.3% for the newer chip. The single-core result in the same test shows a similar story: 123 versus 115, a -6.5% deficit. This pattern repeats in Cinebench R20, where the E5-2630 v3 posts 3640 multi-core and 513 single-core, against 3412 and 481 for the E-2244G, respectively, deltas of -6.3% and -6.2%.

The Cinebench R23 results continue the trend with remarkable consistency. The E5-2630 v3 achieves 8668 multi-core and 1223 single-core, while the E-2244G manages 8126 and 1147. The deltas are -6.3% and -6.2%, respectively. What's striking is the uniformity of these margins; whether the workload is heavily multi-threaded or purely single-threaded, the E5-2630 v3 maintains a lead of roughly six percent across the board. This suggests the advantage is systemic rather than workload-specific. The E-2244G's higher boost clock of 4.80 GHz versus the E5-2630 v3's 3.20 GHz is simply not enough to overcome the older chip's architectural advantages, which include double the cores and 2.5 times the L3 cache.

The average benchmark scores reinforce this picture. The E-2244G averages 2527 across its benchmark suite, while the E5-2630 v3 averages 2507. Both processors sit at the 49th percentile of all CPUs. The nearest rivals for the E-2244G include the Intel Core i3-10325 with an average score of 2530 (a delta of -0.1%), the Intel Xeon E-2144G at 2514 (+0.5%), and the Intel Xeon E5-2643 v3 at 2511 (+0.6%). For the E5-2630 v3, the nearest rivals are the E5-2643 v3 at 2511 (-0.2%), the E-2144G at 2514 (-0.3%), and the Intel Core i5-1155G7 at 2496 (+0.4%). These tight clusters indicate that both chips are competitive within their respective peer groups, but the head-to-head data leaves no doubt about which one comes out ahead in direct comparison.

Architecture Differences

The architectural gap between these two processors is generational and substantial. The E-2244G is built on Intel's 14 nm process node with a die size of 126 mm², while the E5-2630 v3 uses the older 22 nm node with a significantly larger die of 356 mm² and 2,600 million transistors. The E-2244G's Coffee Lake-S WS design packs 4 cores and 8 threads, whereas the E5-2630 v3's Haswell-EP design doubles that to 8 cores and 16 threads. Clock speeds tell the opposite story: the E-2244G runs at a base of 3.80 GHz and boosts to 4.80 GHz, while the E5-2630 v3 operates at a much lower 2.40 GHz base and 3.20 GHz boost.

Cache configurations also differ dramatically. The E-2244G features 64 KB of L1 and 256 KB of L2 per core, with 8 MB of shared L3 cache. The E5-2630 v3 matches the per-core L1 and L2 sizes but offers 20 MB of shared L3 cache, a substantial increase that likely contributes to its consistent benchmark lead. Memory support diverges as well: the E-2244G uses a dual-channel DDR4 memory bus with 42.7 GB/s of bandwidth, while the E5-2630 v3 employs a quad-channel DDR4 configuration with 59.7 GB/s of bandwidth. Both support ECC memory, but the E5-2630 v3's wider memory path provides a clear throughput advantage.

The platform ecosystems are entirely different. The E-2244G uses Intel Socket 1151 with 16 PCIe Gen 3 lanes from the CPU, while the E5-2630 v3 uses Intel Socket 2011-3 with 40 PCIe Gen 3 lanes. The E-2244G includes integrated HD Graphics P630, whereas the E5-2630 v3 has no integrated graphics at all. The E-2244G launched in May 2019 with a launch MSRP of $272, while the E5-2630 v3 launched in September 2014 with a launch MSRP of $667. Power envelopes differ too: the E-2244G has a TDP of 71 watts, while the E5-2630 v3 draws 85 watts. Neither processor has an unlocked multiplier.

The Verdict

The data delivers a clear verdict: the Intel Xeon E5-2630 v3 is the superior processor in every measured benchmark. It wins all six head-to-head comparisons, with margins ranging from -6.2% to -6.5% against the E-2244G. This is particularly notable because the E-2244G has a massive clock speed advantage, a 4.80 GHz boost versus 3.20 GHz, yet still loses in single-threaded tests. The E5-2630 v3's 8 cores, 16 threads, and 20 MB of L3 cache, combined with its quad-channel memory interface, prove more decisive than raw clock speed. The E-2244G's higher frequency and newer 14 nm process cannot compensate for its halved core count and smaller cache.

For buyers choosing between these two, the E5-2630 v3 is the obvious pick based purely on performance data. It offers roughly six percent better performance across Cinebench R15, R20, and R23 in both multi-core and single-core tests. The E-2244G does have advantages in platform specifics, it includes integrated graphics, uses a more common socket, and consumes less power, but these do not translate into benchmark wins. The E5-2630 v3's lower clock speeds are offset by its superior core count, cache size, and memory bandwidth. The only scenario where the E-2244G makes sense is if the workload demands its specific platform features, such as the integrated GPU or the lower TDP, since the performance gap is not enormous.

Where Each One Wins

The Intel Xeon E5-2630 v3 wins across every benchmark category, making it the clear choice for raw compute performance. Its victories span both multi-core and single-core workloads, from Cinebench R15 through R23. The 8-core, 16-thread configuration with 20 MB of L3 cache and quad-channel DDR4 memory at 59.7 GB/s bandwidth gives it a decisive edge in heavily threaded server and workstation tasks. The 40 PCIe Gen 3 lanes also make it more suitable for systems requiring substantial I/O expansion, such as multiple GPUs or high-speed storage controllers. Its larger 356 mm² die with 2,600 million transistors indicates a more complex, capable silicon design.

The Intel Xeon E-2244G wins in platform-level considerations rather than benchmark performance. Its 71-watt TDP is lower than the E5-2630 v3's 85 watts, making it more power-efficient for the same socket generation. The integrated HD Graphics P630 eliminates the need for a discrete GPU in basic display tasks. Its Socket 1151 compatibility and launch MSRP of $272 are notably more accessible than the E5-2630 v3's Socket 2011-3 and $667 launch MSRP. The higher base and boost clocks of 3.80 GHz and 4.80 GHz respectively mean that in real-world scenarios not captured by the benchmark suite, such as lightly threaded legacy applications, it may feel more responsive. However, the benchmark data shows that even in single-core Cinebench tests, the E5-2630 v3 maintains a lead, so the practical benefit of the higher clocks remains uncertain. For most users, the E5-2630 v3's consistent six percent advantage in every measured test makes it the superior choice.
