Intel Xeon E-2176M vs Intel Xeon E-2226G Comparison

The Intel Xeon E-2176M and Intel Xeon E-2226G are both six-core Coffee Lake server and workstation processors, yet they target different physical platforms and thread configurations. The E-2176M is a mobile-oriented part on Intel BGA 1440 with a 45 W TDP, while the E-2226G is a socketed part on Intel Socket 1151 with an 80 W TDP. The recorded benchmarks show the E-2226G winning every head-to-head test, but the margins are narrow, ranging from 2.4% to 3%. The E-2176M counters with Hyper-Threading, offering 12 threads against the E-2226G’s six, and a lower power envelope. The data indicates a close contest where the choice hinges on platform compatibility, power constraints, and the need for simultaneous multithreading rather than raw benchmark dominance.

The Verdict

The benchmark results consistently favor the Intel Xeon E-2226G across all recorded workloads. In Cinebench R15 multicore, the E-2226G scores 944 against 921 for the E-2176M, a 2.4% advantage. The single-core R15 test shows a 3% lead for the E-2226G, with scores of 133 and 129 respectively. The pattern repeats in Cinebench R20, where the E-2226G posts 3934 multicore and 555 single-core, versus 3838 and 541 for the E-2176M, representing 2.4% and 2.5% leads. Cinebench R23 confirms the trend: the E-2226G reaches 9368 multicore and 1322 single-core, while the E-2176M manages 9140 and 1290, again a 2.4% gap in both tests. Across the six recorded head-to-head benchmarks, the E-2226G wins all of them.

This consistency suggests that the E-2226G’s higher clock speeds, with a base of 3.40 GHz and boost of 4.70 GHz, provide a tangible performance edge over the E-2176M’s 2.70 GHz base and 4.40 GHz boost. The E-2176M does hold one structural advantage: its 12 threads double the E-2226G’s six threads, which can benefit highly parallel workloads. However, the recorded multicore benchmarks do not reflect this potential advantage, as the E-2226G still wins the multicore tests despite having half the threads. This indicates that the E-2176M’s thread count does not translate into a measured win in the database’s Cinebench suite.

The E-2176M also carries a significantly lower TDP of 45 W versus 80 W for the E-2226G. For systems constrained by cooling or power delivery, particularly compact workstations, this difference is substantial. The E-2176M’s BGA 1440 socket means it is soldered to the motherboard, making it a choice for integrated, often mobile or space-limited designs. The E-2226G’s Socket 1151 allows for a replaceable processor, which suits traditional desktop-style workstations.

In terms of average benchmark score, the E-2176M records 2751, while the E-2226G records 2709. This places the E-2176M slightly ahead in the overall average, despite losing every head-to-head test. The discrepancy arises because the E-2176M has Geekbench scores included in its average (4787 multicore and 1362 single-core), while the E-2226G lacks Geekbench data in the database. The E-2176M also has a higher percentile ranking relative to all CPUs, though both sit at the 50th percentile. The E-2176M’s nearest rivals include the AMD Ryzen 3 4300GE, which scores 2759 and trails by 0.3%, and the AMD EPYC 7261 at 2740, which leads by 0.4%. The E-2226G’s nearest rivals include the AMD Ryzen 5 PRO 5650U at 2713, which trails by 0.2%, and the Intel Xeon E5-2640 v3 at 2703, which leads by 0.2%.

For buyers prioritizing measured Cinebench performance, the E-2226G is the clear pick. For those needing a lower-power, higher-thread-count processor in a soldered form factor, the E-2176M presents a compelling alternative. The E-2226G’s launch MSRP was $255, while the E-2176M’s was $450, though the database does not analyze price-to-performance ratios. The E-2176M offers a lower TDP and more threads, making it suitable for dense or thermally limited environments, while the E-2226G offers higher clocks and a socketed upgrade path. The data shows a near-tie in average performance, so the final decision rests on platform and power requirements rather than benchmark supremacy.

Architecture Differences

Both processors share the Coffee Lake architecture and are built on Intel’s 14 nm process node. The die size is identical at 154 mm², and both belong to the Xeon E generation labeled Coffee Lake. The E-2176M carries the codename Coffee Lake-H, indicating a high-performance mobile variant, while the E-2226G uses Coffee Lake-S WS, a workstation-oriented desktop variant. This codename distinction aligns with their physical differences: the E-2176M uses the Intel BGA 1440 socket, which is a ball-grid array soldered directly to the motherboard, while the E-2226G uses Intel Socket 1151, a land-grid array that allows processor replacement.

The core and thread configuration is the most significant architectural divergence. Both have six physical cores, but the E-2176M supports 12 threads via Hyper-Threading, while the E-2226G supports only six threads. This means the E-2176M can process two threads per core, whereas the E-2226G processes one thread per core. The cache hierarchy is identical: 64 KB of L1 per core, 256 KB of L2 per core, and 12 MB of shared L3 cache. The memory support is also the same, with dual-channel DDR4 and a bandwidth of 42.7 GB/s, plus ECC capability on both.

The integrated graphics differ slightly. The E-2176M includes UHD Graphics P630, while the E-2226G includes HD Graphics P630. Both are integrated GPU solutions, but the naming suggests a different tier within Intel’s graphics lineup. The PCIe implementation is identical: Gen 3 with 16 lanes from the CPU only. The market segment for both is listed as Server and Workstation, and both are marked as end-of-life products. The E-2176M was released in April 2018, while the E-2226G followed in May 2019, a gap of just over a year.

The process node, foundry, and die size are shared, which means the fundamental transistor technology is the same. The architectural differences therefore center on packaging, threading, and clock behavior rather than microarchitectural execution resources. The E-2176M’s lower TDP of 45 W suggests a more power-efficient bin, likely optimized for battery or thermal-constrained environments, while the E-2226G’s 80 W TDP allows higher sustained clock speeds. The E-2226G’s base clock of 3.40 GHz is 0.70 GHz higher than the E-2176M’s 2.70 GHz, and its boost clock of 4.70 GHz is 0.30 GHz higher, directly explaining its benchmark wins.

The integrated graphics differ: UHD Graphics P630 for the E-2176M versus HD Graphics P630 for the E-2226G. The release dates are April 2018 for the E-2176M and May 2019 for the E-2226G. The launch MSRP was $450 for the E-2176M and $255 for the E-2226G. The part numbers are SR3YX for the E-2176M and SRF7F for the E-2226G. The codenames differ as well, with Coffee Lake-H for the E-2176M and Coffee Lake-S WS for the E-2226G.

Shared specifications include the 14 nm process node, 154 mm² die size, six cores, identical cache sizes, dual-channel DDR4 support, 42.7 GB/s memory bandwidth, ECC memory support, Gen 3 PCIe with 16 lanes, and the server and workstation market segment. Both are end-of-life and neither has an unlocked multiplier. The series names differ, with the E-2176M in the Xeon E-2100 series and the E-2226G in the Xeon E-2200 series. The average benchmark score is 2751 for the E-2176M and 2709 for the E-2226G. The percentile versus all CPUs is 50 for both.

Head-to-Head Benchmarks

The head-to-head results show a clean sweep for the Intel Xeon E-2226G. In Cinebench R15 multicore, the E-2226G scores 944 against 921 for the E-2176M, a 2.4% advantage. The single-core R15 test shows a 3% lead, with 133 versus 129. These are the largest and smallest deltas in the set, respectively. The multicore R15 result is notable because the E-2176M has 12 threads to the E-2226G’s six, yet it still trails. This suggests that the E-2226G’s higher clocks compensate for the lack of Hyper-Threading in this workload.

Cinebench R20 multicore continues the pattern: the E-2226G scores 3934, which is 2.4% ahead of the E-2176M’s 3838. The single-core R20 test shows a 2.5% lead, with 555 versus 541. The R20 results are slightly closer in percentage terms than R15 single-core, but the direction is unchanged. The E-2226G’s multicore lead in R20 is 96 points, while the single-core lead is 14 points. Both margins are consistent with the clock advantage.

Cinebench R23 multicore gives the E-2226G a score of 9368 against 9140 for the E-2176M, a 2.4% lead. The single-core R23 test shows 1322 versus 1290, also a 2.4% lead. The R23 multicore difference is 228 points, the largest absolute gap in the dataset, while the single-core difference is 32 points. Across all six tests, the E-2226G wins by margins between 2.4% and 3%, with no test showing a win for the E-2176M.

The E-2176M does have a Geekbench score that the E-2226G lacks: 4787 multicore and 1362 single-core. This contributes to its higher average benchmark score of 2751, compared with 2709 for the E-2226G. The database includes no Geekbench result for the E-2226G, so a direct comparison in that test is not possible. The head-to-head dataset is limited to Cinebench R15, R20, and R23, all of which favor the E-2226G.

The E-2176M’s nearest rivals in the database include the AMD Ryzen 3 4300GE with an average score of 2759, which trails by 0.3%, and the AMD Ryzen 3 5400U at 2765, which trails by 0.5%. The AMD EPYC 7261 scores 2740, leading the E-2176M by 0.4%. The E-2226G’s nearest rivals include the AMD Ryzen 5 PRO 5650U at 2713, trailing by 0.2%, and the Intel Xeon D-1577 at 2715, also trailing by 0.2%. The Intel Xeon E5-2640 v3 and Intel Core i7-1185G7E both score 2703, leading the E-2226G by 0.2%.

The data indicates that the E-2226G is the faster processor in every measured Cinebench test, but the E-2176M holds a slight edge in average score due to its additional Geekbench results. The E-2176M’s 12 threads and 45 W TDP make it a strong candidate for power-sensitive systems, while the E-2226G’s clock speed advantage makes it the better choice for raw performance in the recorded benchmarks. The six head-to-head wins for the E-2226G, with no wins for the E-2176M, provide a clear quantitative verdict in favor of the E-2226G for users prioritizing Cinebench-style workloads.
