CPU Comparison

The Intel Xeon E-2244G and Intel Xeon E5-2643 v3 are both end-of-life server/workstation processors, but they represent vastly different design philosophies from Intel. The E-2244G is a modern, high-frequency Coffee Lake part aimed at entry-level single-socket systems, while the E5-2643 v3 is a higher-core-count Haswell-EP chip designed for multi-socket enterprise platforms. The benchmark data shows a surprisingly consistent outcome: the older E5-2643 v3 wins every single head-to-head test, despite the E-2244G’s newer architecture and much higher clock speeds.

Head-to-Head Benchmarks

The results are unambiguous. Across all six Cinebench tests, the Intel Xeon E5-2643 v3 takes the win, though the margins are relatively narrow. In the Cinebench R15 multicore test, the E5-2643 v3 scores 875 against the E-2244G’s 818, a 6.5% advantage. The single-core R15 result follows the same pattern: 123 versus 115, also a 6.5% lead for the E5-2643 v3.

Moving to the more modern Cinebench R20 suite, the margins tighten slightly. The E5-2643 v3 posts 3646 in multicore versus 3412 for the E-2244G, a 6.4% gap. In single-core R20, the scores are 514 and 481, again a 6.4% difference. The trend holds in Cinebench R23, where the E5-2643 v3 scores 8682 multicore and 1225 single-core, versus 8126 and 1147 for the E-2244G. Every test shows the same 6.4-6.5% delta in favor of the six-core Haswell part.

This is a notable result because the E-2244G has a significant clock advantage. Its base clock of 3.80 GHz and boost clock of 4.80 GHz dwarf the E5-2643 v3’s 3.40 GHz base and 3.70 GHz boost. Yet the E5-2643 v3’s two extra cores and 12 threads compensate for the clock deficit, delivering consistent wins in both multi-threaded and single-threaded workloads. The data suggests that the E5-2643 v3’s older but wider architecture, combined with a 20 MB shared L3 cache, provides a more effective IPC per clock in these Cinebench workloads than the E-2244G’s newer Coffee Lake design.

The average benchmark scores confirm the near-parity of the two parts. The E-2244G has an average benchmark score of 2527, while the E5-2643 v3 sits at 2511, a difference of just 0.6% in favor of the E-2244G. This puts the two chips in the same performance class overall, even though the E5-2643 v3 wins every individual Cinebench test. Both processors occupy the 49th percentile among all CPUs in the database, meaning they are statistically equivalent in overall standing. The nearest rival lists reinforce this: the E-2244G’s closest competitor is the Intel Core i3-10325 (average score 2530, delta -0.1%), while the E5-2643 v3’s closest is the Intel Xeon E-2144G (average score 2514, delta -0.1%).

Architecture Differences

The two processors come from different eras and different process nodes. The E-2244G is built on Intel’s 14 nm process, using the Coffee Lake architecture (codename Coffee Lake-S WS) from the Xeon E-2200 series. Its die size is a relatively small 126 mm². In contrast, the E5-2643 v3 uses the older 22 nm process, with the Haswell-EP architecture (codename Haswell-EP) from the Xeon E5 v3 generation. Its die is substantially larger at 356 mm², and it packs 2,600 million transistors.

Core and thread counts are a major differentiator. The E-2244G offers 4 cores and 8 threads, while the E5-2643 v3 provides 6 cores and 12 threads. The cache hierarchy also differs significantly. Both chips have 64 KB of L1 cache per core and 256 KB of L2 per core, but the shared L3 cache is where the gap widens: the E-2244G has 8 MB shared, while the E5-2643 v3 has 20 MB shared. That extra cache is likely a key factor in the E5-2643 v3’s benchmark wins.

Clock speeds favor the E-2244G heavily. It runs at 3.80 GHz base and 4.80 GHz boost, compared to the E5-2643 v3’s 3.40 GHz base and 3.70 GHz boost. The newer chip also has a much lower TDP of 71 watts versus the E5-2643 v3’s 135 watts. The E-2244G includes integrated HD Graphics P630, while the E5-2643 v3 has no integrated graphics at all. Both support ECC memory and DDR4, but the memory channels differ: the E-2244G is dual-channel with 42.7 GB/s bandwidth, while the E5-2643 v3 is quad-channel with 68.3 GB/s. PCIe lanes also favor the E5-2643 v3, which offers 40 lanes versus 16 for the E-2244G.

The sockets are incompatible: the E-2244G uses Intel Socket 1151, while the E5-2643 v3 uses Intel Socket 2011-3. Neither processor has an unlocked multiplier. The release dates are separated by nearly five years, with the E5-2643 v3 launching in September 2014 and the E-2244G in May 2019.

Where Each One Wins

The Intel Xeon E5-2643 v3 is the clear winner in Cinebench performance, taking all six head-to-head tests. Its 6-core, 12-thread configuration and 20 MB L3 cache deliver consistent 6.4-6.5% advantages over the E-2244G across R15, R20, and R23, in both single-core and multi-core runs. The E5-2643 v3 also wins on platform capabilities: it offers quad-channel memory with 68.3 GB/s of bandwidth, 40 PCIe Gen 3 lanes, and a much larger die with 2,600 million transistors. For workloads that leverage many cores, large caches, or high memory bandwidth, the E5-2643 v3 is the better choice.

The Intel Xeon E-2244G wins on efficiency and modern platform features. Its TDP of 71 watts is nearly half the E5-2643 v3’s 135 watts, making it far more power-efficient. It has a much higher boost clock of 4.80 GHz, which could be an advantage in lightly-threaded, latency-sensitive tasks, though the benchmark data does not show this benefit in Cinebench. The E-2244G includes integrated HD Graphics P630, eliminating the need for a discrete GPU in basic display scenarios. It also uses the newer 14 nm process and has a smaller 126 mm² die, which contributes to its lower power draw. The E-2244G’s launch MSRP was $272, versus $1552 for the E5-2643 v3, though pricing is noted here only as a launch specification.

For new system builds, the E-2244G’s Socket 1151 platform is more common in entry-level workstations, while the E5-2643 v3’s Socket 2011-3 targets multi-socket enterprise servers. The E5-2643 v3’s 40 PCIe lanes and quad-channel memory make it more suitable for I/O-heavy or memory-bandwidth-intensive workloads. The E-2244G’s higher clocks and lower power draw make it a better fit for compact, energy-conscious single-socket servers that do not need maximum core counts. In aggregate, the data shows the two chips are nearly equal in overall average benchmark score, differing by only 0.6%, so the choice between them will come down to platform requirements rather than raw performance.
