Intel Core i7-11700T vs Intel Xeon E-2278GE Comparison

Head-to-Head Benchmarks

The recorded data presents a remarkably consistent picture across every Cinebench iteration. The Intel Xeon E-2278GE wins all six head-to-head benchmark comparisons, with no single victory going to the Core i7-11700T. The margin is uniform, hovering near 5% in every test.

In Cinebench R15 multicore, the Xeon scores 1372 against 1304 for the Core i7, a delta of 5.2%. The single-core R15 result shows 193 versus 184, a 4.9% advantage for the Xeon. Moving to Cinebench R20, the multicore gap repeats at 5.2%, with the Xeon posting 5719 and the Core i7 reaching 5436. The R20 single-core test shows 807 against 767, again a 5.2% difference. Cinebench R23 multicore continues the pattern: 13619 for the Xeon versus 12945 for the Core i7, a 5.2% lead. The R23 single-core result is 1922 against 1827, also 5.2% ahead.

What stands out is the consistency of the delta across workloads. Whether the test stresses all eight cores or just a single thread, the Xeon maintains nearly the same percentage advantage. This suggests the performance gap is structural rather than workload-dependent. The Xeon also holds an edge in average benchmark score, 3939 versus 3864, a difference of roughly 75 points. The percentile rankings align with this: the Xeon sits at the 57th percentile among all CPUs, while the Core i7 lands at the 56th.

The Core i7 does have additional Geekbench entries in the database that the Xeon lacks, scoring 6621 multicore and 1824 singlecore. These results cannot be compared directly to the Xeon because no corresponding Geekbench run exists for the older part, but they do establish a reference point for the Core i7's absolute capability.

The nearest rival data puts both processors in similar company. The Xeon's closest competitors include the AMD Ryzen 9 5900HS at a 0.4% higher average score, the AMD Ryzen 3 7330U at 0.5% lower, the Intel Xeon E5-2669 v3 at 0.5% lower, and the Intel Core i7-6900K at 0.8% lower. The Core i7-11700T's nearest rivals include the AMD Ryzen Embedded V2718 at 0.3% lower, the Intel Xeon E-2286M at 1.1% higher, the AMD Ryzen 5 4600GE at 1.1% lower, and the AMD Ryzen 9 4900H at 1.1% higher. Both chips sit in a crowded mid-range band where small percentage swings separate neighbors.

The Verdict

The data points to a clear winner on pure compute performance. The Intel Xeon E-2278GE outperforms the Intel Core i7-11700T in every benchmark category recorded, with margins between 4.9% and 5.2%. For workloads that rely on sustained multicore throughput or single-thread responsiveness, the Xeon is the stronger choice according to the measurements.

However, the choice is not simply about raw scores. The Core i7-11700T carries a 35 TDP against the Xeon's 80 TDP, meaning it draws considerably less power under load. The database shows the Xeon's power envelope is more than double that of the Core i7. For systems where thermal headroom or energy consumption is a design constraint, the Core i7's efficiency profile may be more attractive despite its lower scores.

The platform differences also matter. The Xeon uses Intel Socket 1151, while the Core i7 uses Intel Socket 1200. They are not interchangeable. The Xeon supports ECC memory, the Core i7 does not. The Core i7 offers PCIe Gen 4 with 20 lanes, while the Xeon provides PCIe Gen 3 with 16 lanes. The Core i7 also shows a higher memory bandwidth of 51.2 GB/s versus 42.7 GB/s for the Xeon, despite the Xeon winning every CPU benchmark.

Who should pick which? From the data alone, the Xeon suits scenarios where maximum CPU compute is the priority and the power budget can accommodate an 80 TDP part. The Core i7 suits scenarios where lower power consumption, newer PCIe support, and higher memory bandwidth matter more than the roughly 5% CPU performance deficit. The Xeon's ECC support and server/workstation market segment also point toward reliability-focused deployments, while the Core i7's desktop segment and integrated UHD Graphics 750 suggest a more general-purpose role.

Specification Differences

The two processors differ in several core specifications. The Xeon has a base clock of 3.30 GHz and a boost clock of 4.70 GHz. The Core i7 has a base clock of 1400.00 MHz and a boost clock of 4.60 GHz. The boost clocks are close, but the base clock gap is substantial, likely explaining part of the Xeon's lead in sustained workloads.

The TDP difference is significant: the Xeon is rated at 80, while the Core i7 is rated at 35. The socket is also different, with the Xeon on Intel Socket 1151 and the Core i7 on Intel Socket 1200. The Xeon has a die size of 180 mm², while the Core i7 has a die size of 276 mm². Both use a 14 nm process node and are manufactured by Intel.

Memory bandwidth differs, with the Xeon at 42.7 GB/s and the Core i7 at 51.2 GB/s. The Xeon supports ECC memory; the Core i7 does not. The PCIe configuration also differs: the Xeon provides Gen 3 with 16 lanes, while the Core i7 provides Gen 4 with 20 lanes. The integrated graphics are different as well, with the Xeon featuring UHD Graphics P630 and the Core i7 featuring UHD Graphics 750.

The cache layout differs per core. The Xeon has 64 KB of L1 cache per core and 256 KB of L2 cache per core. The Core i7 has 80 KB of L1 cache per core and 512 KB of L2 cache per core. Both share 16 MB of L3 cache. The Core i7 has larger per-core caches, yet still trails in benchmark scores.

The release dates and market segments differ. The Xeon launched on 2019-06-10, aimed at the server/workstation segment, with a launch MSRP of $519. The Core i7 launched on 2021-03-15, aimed at the desktop segment, with a launch MSRP of $323. Both are end-of-life products. Neither has an unlocked multiplier.

Architecture Differences

The Xeon is built on the Coffee Lake architecture, specifically Coffee Lake-S WS, part of the Xeon E-2200 series. The Core i7 uses the Rocket Lake architecture, part of the Core 11th Gen series. Both are fabricated on a 14 nm node by Intel, but they represent different architectural generations.

The Xeon's generation is listed as "Xeon E (Coffee Lake)", while the Core i7's generation is "Core i7 (Rocket Lake-S)". The codenames reflect this: Coffee Lake-S WS for the Xeon and Rocket Lake for the Core i7. Despite the architectural differences, both chips have 8 cores and 16 threads, so the core count is identical.

Cache architecture shows meaningful divergence. The Xeon provides 64 KB of L1 per core and 256 KB of L2 per core. The Core i7 provides 80 KB of L1 per core and 512 KB of L2 per core. This means the Core i7 has 25% more L1 cache and double the L2 cache per core. Yet the shared L3 cache is identical at 16 MB. The larger per-core caches in the Core i7 do not translate into benchmark wins in the recorded data.

The memory controller differs in bandwidth, with the Core i7 supporting 51.2 GB/s versus 42.7 GB/s for the Xeon. The Core i7 also supports a newer PCIe generation, Gen 4, with more lanes, 20 versus 16. The Xeon's ECC memory support is a notable feature absent from the Core i7, reflecting its server/workstation positioning.

The integrated graphics are different SKUs: UHD Graphics P630 for the Xeon and UHD Graphics 750 for the Core i7. Both are integrated solutions, but the database does not include graphics benchmark results for either, so their relative GPU performance cannot be assessed from this data. The Core i7's die size of 276 mm² is substantially larger than the Xeon's 180 mm², which may reflect the different integrated graphics and architecture changes.

Where Each One Wins

The Intel Xeon E-2278GE wins every CPU benchmark in the head-to-head comparison. Its margins are consistent at 5.2% for most tests, with a slightly smaller 4.9% lead in Cinebench R15 single-core. This makes it the clear choice for compute-bound workloads such as rendering, compilation, or any task where Cinebench-style multithreaded performance is representative. Its server/workstation market segment and ECC memory support further position it for reliability-focused environments where data integrity is critical.

The Intel Core i7-11700T wins on platform-level specifications rather than raw CPU benchmarks. Its 35 TDP makes it far more power-efficient than the Xeon's 80 TDP, which could be decisive in compact or thermally constrained systems. It offers PCIe Gen 4 with 20 lanes compared to the Xeon's PCIe Gen 3 with 16 lanes, enabling faster connectivity for modern GPUs and NVMe storage. Its memory bandwidth of 51.2 GB/s exceeds the Xeon's 42.7 GB/s, which could benefit memory-sensitive workloads even if the CPU cores are slightly slower. The larger per-core caches, 80 KB L1 and 512 KB L2, may also help in specific access patterns, though the benchmark data does not show a win in the tested Cinebench suite.

The Core i7 also has Geekbench results in the database, scoring 6621 multicore and 1824 singlecore, providing an additional performance reference that the Xeon lacks. For users who prioritize power efficiency, newer PCIe support, higher memory bandwidth, or a desktop-oriented platform, the Core i7 is the better fit. For users who prioritize maximum CPU compute and ECC reliability, the Xeon is the stronger option. The data does not show a scenario where the Core i7 beats the Xeon in raw processing power, but it clearly wins on efficiency and platform features.
