CPU Comparison

The Intel Xeon E-2176G and Intel Xeon E-2246G are two 6-core, 12-thread server/workstation processors built on the same 14nm Coffee Lake architecture. Despite their near-identical specifications, benchmark data reveals a fascinating split: the newer E-2246G dominates in every Cinebench test, while the older E-2176G posts a decisive victory in Geekbench multicore. This creates an unusual scenario where the "winner" depends entirely on which benchmark suite you trust, making the choice between them less about raw capability and more about workload characteristics.

FAQ

Q: Which processor has the higher boost clock?

A: The Intel Xeon E-2246G boosts to 4.80 GHz, while the Intel Xeon E-2176G reaches 4.70 GHz. This 0.10 GHz advantage likely contributes to the E-2246G's consistent single-core wins across all benchmark suites.

Q: How do the two processors compare in Geekbench multicore performance?

A: The Intel Xeon E-2176G scores 6331, which is 5.7% higher than the E-2246G's 5988. This is the only benchmark in the head-to-head set where the E-2176G wins, and it is a substantial margin.

Q: Are both processors compatible with the same motherboard socket?

A: Yes, both use the Intel Socket 1151. This means system builders can potentially swap between them without changing the motherboard, assuming BIOS support is available.

Q: What is the difference in their launch MSRP?

A: The Intel Xeon E-2176G had a launch MSRP of $367, while the Intel Xeon E-2246G was launched at $311. The newer part was priced lower at introduction.

Q: Do both processors support ECC memory?

A: Yes, both support ECC memory. They also both feature dual-channel DDR4 memory with 42.7 GB/s of bandwidth, making them suitable for workstation reliability.

Q: Which processor has a higher average benchmark score?

A: The Intel Xeon E-2176G has an average benchmark score of 3502, while the E-2246G scores 3492. The difference is only 0.3%, placing them in a statistical tie.

Architecture Differences

Both processors share the same fundamental architecture: Coffee Lake-S WS on a 14nm process, with a 154 mm² die size. They both feature 6 cores and 12 threads, with identical cache configurations: 64 KB L1 per core, 256 KB L2 per core, and 12 MB of shared L3. Neither has an unlocked multiplier.

The key architectural difference lies in their generation and clock tuning. The E-2176G belongs to the Xeon E-2100 series, released in July 2018, while the E-2246G is from the Xeon E-2200 series, released in May 2019. The E-2176G has a base clock of 3.70 GHz and a boost clock of 4.70 GHz. The E-2246G starts lower at 3.60 GHz base but boosts higher to 4.80 GHz. This inverted clock profile – lower base, higher boost – suggests Intel refined the silicon's power management for the newer part, potentially allowing it to sustain higher boost frequencies under load while idling lower.

Both processors integrate HD Graphics P630 and support DDR4 memory in dual-channel mode with 42.7 GB/s of bandwidth. They also share the same PCIe Gen 3 configuration with 16 lanes from the CPU. The part numbers differ (SR3WS vs SRF7G), confirming they are distinct silicon revisions despite the architectural similarity. Both are marked as end-of-life production status, targeting the server/workstation market segment.

Where Each One Wins

The head-to-head data paints a clear picture: the E-2246G wins 7 out of 8 benchmarks. Its victories span both single-core and multi-core workloads across Cinebench R15, R20, and R23. This suggests the E-2246G is the better choice for general rendering tasks, 3D modeling, and any workload that relies on sustained all-core performance.

The E-2176G's sole victory is in Geekbench multicore, where it scores 6331 versus 5988 for the E-2246G – a 5.7% advantage. This is a significant outlier given that the E-2246G wins Cinebench multicore tests by 1.1% across the board. The Geekbench multicore test may be more sensitive to the E-2176G's higher base clock of 3.70 GHz, which could provide an advantage in shorter, bursty workloads that don't allow the E-2246G to reach its higher boost state. Conversely, the E-2246G's superior boost clock appears to benefit longer, sustained rendering workloads in Cinebench.

For single-core performance, the E-2246G wins every test, with margins ranging from 1.0% in Cinebench R20 to 2.5% in Geekbench single-core. This makes the E-2246G the clear choice for lightly-threaded applications like legacy software, scripting, or database queries that depend on single-thread speed.

Specification Differences

The two processors are nearly identical on paper, differing in only a few key fields:

• Base Clock: The E-2176G runs at 3.70 GHz, while the E-2246G runs at 3.60 GHz – a 0.10 GHz advantage for the older part.
• Boost Clock: The E-2246G boosts to 4.80 GHz, while the E-2176G maxes out at 4.70 GHz – a 0.10 GHz advantage for the newer part.
• Series and Release Date: The E-2176G is from the Xeon E-2100 series (released July 2018), while the E-2246G is from the Xeon E-2200 series (released May 2019).
• Part Number: The E-2176G uses SR3WS, while the E-2246G uses SRF7G.
• Launch MSRP: The E-2176G launched at $367, while the E-2246G launched at $311.

Everything else – cores, threads, cache, TDP of 80, socket, architecture, process node, memory support, ECC capability, integrated graphics, and PCIe lanes – is identical. This makes the clock speed trade-off the primary differentiator between the two chips.

Head-to-Head Benchmarks

The benchmark data reveals a remarkably consistent pattern. In Cinebench R15 multicore, the E-2246G scores 1181 against the E-2176G's 1168, a 1.1% advantage. The single-core R15 test shows a similar story: 166 versus 164, a 1.2% edge for the E-2246G. Moving to Cinebench R20, the E-2246G wins multicore 4922 to 4867 (1.1%) and single-core 694 to 687 (1.0%). The R23 results continue the trend: multicore 11720 versus 11589 (1.1%) and single-core 1654 versus 1636 (1.1%).

The E-2246G's consistency across all three Cinebench versions – with nearly identical 1.1% margins in both single and multi-core tests – suggests its higher boost clock provides a uniform advantage in rendering workloads. The E-2176G's higher base clock does not translate into any Cinebench advantage.

The Geekbench results break this pattern dramatically. In Geekbench multicore, the E-2176G scores 6331, which is 5.7% higher than the E-2246G's 5988. This is the largest margin in the entire comparison, and it favors the older processor. However, in Geekbench single-core, the E-2246G wins 1613 to 1573, a 2.5% margin that is more than double its Cinebench single-core advantage.

This divergence raises questions about what the Geekbench multicore test measures differently from Cinebench multicore. The E-2176G's higher base clock may allow it to maintain higher frequencies during the shorter, more varied Geekbench workload, while Cinebench's sustained rendering load allows the E-2246G to reach and maintain its higher boost clock.

The Verdict

The data supports a clear recommendation for most users: the Intel Xeon E-2246G is the superior choice for rendering, 3D modeling, and typical workstation workloads. It wins every Cinebench test by a consistent 1.1% margin in both single-core and multi-core, and it also wins Geekbench single-core by 2.5%. Its lower launch MSRP of $311 versus $367 adds to its appeal, though pricing should not be the primary consideration given the benchmark results.

The Intel Xeon E-2176G is the better option only if your workload closely mirrors the Geekbench multicore test. The 5.7% advantage in that specific benchmark is substantial, potentially translating to real-world gains in applications that exhibit similar bursty, mixed-thread behavior. However, this is a narrow use case, and the E-2176G loses every other benchmark in the comparison.

For most server and workstation buyers, the E-2246G's consistent wins across the Cinebench suite and its higher boost clock make it the logical pick. The E-2176G remains a capable alternative for those who prioritize the specific performance profile captured by Geekbench multicore, but the weight of evidence favors the newer part. Both processors occupy the same 55th percentile against all CPUs, indicating they deliver nearly identical overall performance levels, but the E-2246G achieves this with a higher boost clock and lower launch price.
