CPU Comparison

The Intel Xeon E-2104G and the Intel Core i5-6500TE are both four-core, four-thread processors on the Intel Socket 1151 platform, yet they serve different market segments. The data shows a clear performance hierarchy between them, but the choice is not solely about raw benchmark scores. The Xeon E-2104G consistently outperforms the i5-6500TE across every single-threaded and multi-threaded Cinebench test, while the i5-6500TE counters with a significantly lower thermal design power and support for older memory types. This analysis will quantify the performance deltas, examine the architectural and specification differences, and determine which processor is appropriate for which workload.

Head-to-Head Benchmarks

The benchmark results are unambiguous: the Intel Xeon E-2104G wins all six head-to-head comparisons, with margins ranging from 13.3% to 14%. This consistency across different Cinebench versions (R15, R20, and R23) indicates a uniform performance advantage rather than a workload-specific quirk.

In multi-core tests, the Xeon E-2104G scores 488 in Cinebench R15, which is 14% higher than the i5-6500TE’s 428. This gap persists in Cinebench R20, where the Xeon’s 2035 score beats the i5’s 1787 by 13.9%. The most recent Cinebench R23 multi-core test shows a similar story: 4847 versus 4255, again a 13.9% delta. These results suggest that for heavily threaded workloads, the Xeon E-2104G provides a substantial and consistent lead.

Single-core performance follows the exact same pattern. In Cinebench R15 single-core, the Xeon E-2104G scores 68 against the i5-6500TE’s 60, a 13.3% advantage. Cinebench R20 single-core shows the Xeon at 287 versus 252, a 13.9% lead. Finally, Cinebench R23 single-core delivers 684 for the Xeon versus 600 for the i5, a 14% margin. The near-constant delta across all tests indicates that the Xeon’s advantage is rooted in its higher base clock speed, since both processors lack a boost clock on the Xeon side.

The aggregate benchmark scores reinforce this picture. The Xeon E-2104G has an average benchmark score of 1402, while the i5-6500TE sits at 1399. This 0.2% difference is minimal, but the head-to-head data shows the Xeon’s lead is more pronounced in specific Cinebench workloads. Notably, the i5-6500TE has additional Geekbench scores (2749 multi-core, 1062 single-core) that are not present in the Xeon’s dataset, so a direct comparison across all benchmark types is not possible. However, the Cinebench suite alone is sufficient to establish the Xeon E-2104G as the faster processor.

When placed against their shared rivals, both processors occupy the same performance tier. The Xeon E-2104G’s nearest rival is the Intel Xeon E3-1220 v5 with a delta of 0.1%, and it is 0.2% ahead of the i5-6500TE. The i5-6500TE’s nearest rival list shows it is 0.2% behind the Xeon E-2104G. Both processors also sit near the Intel Pentium Gold G7400TE and the Intel Xeon E3-1240L v3, with deltas under 0.5%. This clustering means that while the Xeon E-2104G beats the i5-6500TE in every head-to-head test, the overall performance difference between these two parts is small in the context of the broader CPU market.

The Verdict

The data supports a clear verdict for performance-seeking users: the Intel Xeon E-2104G is the superior choice. It wins every head-to-head benchmark by approximately 14%, which is a meaningful margin for CPU-bound tasks like video encoding or 3D rendering. Its higher base clock of 3.20 GHz versus the i5-6500TE’s 2.30 GHz, combined with a larger 8 MB L3 cache versus 6 MB, explains the consistent advantage. For users who prioritize raw throughput and are not constrained by power budgets, the Xeon E-2104G is the definitive pick.

However, the i5-6500TE is not without merit. Its 35 W TDP is nearly half the Xeon E-2104G’s 65 W, making it a more attractive option for compact or passively cooled systems where heat dissipation is a concern. The i5-6500TE also supports both DDR3 and DDR4 memory, whereas the Xeon E-2104G is limited to DDR4, which could be a deciding factor for users upgrading an existing system with DDR3 modules. The i5-6500TE’s lower memory bandwidth of 34.1 GB/s versus 42.7 GB/s on the Xeon is a trade-off, but the flexibility in memory type may be more valuable for some.

For server or workstation deployments, the Xeon E-2104G is the logical choice. It supports ECC memory, a feature absent on the i5-6500TE, and its market segment is explicitly Server/Workstation. The i5-6500TE is classified as Desktop, and its lack of ECC support makes it unsuitable for mission-critical applications where data integrity is paramount. The Xeon also includes UHD Graphics P630, while the i5-6500TE has HD Graphics 530; both are integrated, but the Xeon’s offering is positioned for professional use.

In summary, the Xeon E-2104G should be selected by users who need maximum performance and ECC memory support, even at the cost of higher power consumption. The i5-6500TE should be chosen by users who prioritize low power draw and memory flexibility over raw speed, and who do not require ECC. Both processors are end-of-life, so availability may be limited, but the benchmark data is definitive: the Xeon E-2104G is faster in every measured scenario.

Specification Differences

The two processors differ in several key specifications beyond their benchmark scores. The Intel Xeon E-2104G has a base clock of 3.20 GHz with no boost clock, while the Intel Core i5-6500TE has a lower base clock of 2.30 GHz but offers a boost clock of 3.30 GHz. This means the i5-6500TE can temporarily exceed its base clock under load, but the Xeon’s higher sustained base clock still yields better performance in the tested benchmarks.

The Xeon E-2104G has a TDP of 65 W, compared to the i5-6500TE’s 35 W. Both use the Intel Socket 1151, but the Xeon is based on the Coffee Lake architecture (codename Coffee Lake-S WS), while the i5-6500TE uses Skylake. The L3 cache differs: the Xeon has 8 MB shared, while the i5 has 6 MB shared. Die size also varies slightly, with the Xeon at 126 mm² and the i5 at 122 mm².

Memory support is a major differentiator. The Xeon E-2104G supports only DDR4 with dual-channel memory and a bandwidth of 42.7 GB/s. The i5-6500TE supports both DDR3 and DDR4, also dual-channel, but with a lower bandwidth of 34.1 GB/s. ECC memory is supported only on the Xeon. Integrated graphics differ as well: the Xeon has UHD Graphics P630, while the i5 has HD Graphics 530. The launch MSRP was $193 for the Xeon and $192 for the i5, though pricing is not a factor in this analysis.

The market segment also diverges: the Xeon E-2104G is targeted at Server/Workstation, while the i5-6500TE is a Desktop part. Both have 4 cores and 4 threads, and neither has an unlocked multiplier. The part numbers are SR3WV for the Xeon and SR2LR for the i5.

Architecture Differences

The architectural divide between these two parts is significant, even though they share the same 14 nm process node and Intel foundry. The Intel Xeon E-2104G is built on the Coffee Lake architecture, specifically the Coffee Lake-S WS variant, which is a refinement of Intel’s 14 nm process. Its codename is Coffee Lake-S WS, and it belongs to the Xeon E-2100 series. The Intel Core i5-6500TE, in contrast, uses the older Skylake architecture, with the codename Skylake, and belongs to the Core i5 (Skylake) generation.

Both processors have 4 cores and 4 threads, meaning they lack Hyper-Threading. The Xeon E-2104G has a base clock of 3.20 GHz, while the i5-6500TE has a base clock of 2.30 GHz and a boost clock of 3.30 GHz. The Xeon compensates for its lack of boost with a higher base clock, which is a common design choice for server parts that need predictable, sustained performance.

Cache hierarchy is similar at the L1 and L2 levels, with both having 64 KB of L1 cache per core and 256 KB of L2 cache per core. The difference lies in the L3 cache: the Xeon E-2104G has 8 MB shared, while the i5-6500TE has 6 MB shared. This additional 2 MB of L3 cache on the Xeon is likely a factor in its better multi-core performance, as it allows more data to be stored closer to the cores.

The Xeon E-2104G supports ECC memory, which is a hallmark of server platforms, while the i5-6500TE does not. The Xeon also has a higher memory bandwidth (42.7 GB/s) compared to the i5 (34.1 GB/s), despite both using dual-channel memory. The i5-6500TE’s support for DDR3 is a legacy feature, allowing it to be used in systems with older memory modules, but this comes at the cost of bandwidth.

The integrated graphics differ as well: the Xeon E-2104G includes UHD Graphics P630, which is a workstation-oriented GPU, while the i5-6500TE has HD Graphics 530, a consumer-grade solution. The Xeon’s market segment is explicitly Server/Workstation, reflecting its ECC support and higher TDP, while the i5-6500TE is classified as Desktop. Both processors have 16 PCIe Gen 3 lanes (CPU only), which is identical. The die sizes are close, at 126 mm² for the Xeon and 122 mm² for the i5, reflecting the minor architectural changes between Coffee Lake and Skylake.
