Intel Xeon E-2276G

The Intel Xeon E-2276G is a 6-core, 12-thread processor built on the Coffee Lake architecture for server and workstation use. It operates at a base clock of 3.80 GHz and a boost of 4.90 GHz, with an 80W TDP. Its average benchmark score of 3625 places it in the 58th percentile of all CPUs, and it launched with an MSRP of $362. The chip supports ECC memory and includes HD Graphics P630, making it a niche but capable option for single-socket workstations.

How It Compares

The nearest rival, the Intel Xeon E-2286G, posts an average score of 3614, which is 0.3% behind the E-2276G's 3625. This difference is within run-to-run variance, so the two are effectively equivalent in aggregate throughput. The E-2286G is a higher-binned part in the same family, but the data shows no meaningful performance separation.

AMD's Ryzen 7 PRO 1700 averages 3613, also 0.3% behind. The PRO designation targets commercial reliability, but the E-2276G holds a slight edge in the benchmark average. Again, the margin is negligible.

The non-PRO Ryzen 7 1700 is the only rival that leads, with an average of 3637, 0.3% ahead of the E-2276G. This is the closest gap among the four, and the difference is too small to affect real-world application selection.

The mobile Ryzen 5 5625U averages 3610, 0.4% behind. Despite being a low-power laptop chip, it nearly matches the Xeon in aggregate score. This underscores that the E-2276G's performance level is not exceptional; it sits in the middle of the pack.

Power and Thermals

The 80W TDP places the E-2276G in a power class that is easily managed by a conventional air cooler. The integrated HD Graphics P630 adds a minor thermal load, but the total heat output remains modest. A mid-tower chassis with standard airflow will suffice; high-end liquid cooling is unnecessary. The 14nm process node and 154 mm² die size contribute to a reasonable power density. For workstation users who prioritize low noise, a quiet tower cooler will handle this CPU without issue. The end-of-life status means no new thermal guidance is forthcoming, but the 80W class is well understood.

Single-Thread vs Multi-Thread Behavior

The benchmark results show a clear strength in single-threaded performance. In Cinebench R23, the E-2276G scores 1695 in single-core and 12007 in multi-core. The single-core figure is high relative to the multi-core score, indicating that the 4.90 GHz boost clock is effectively utilized. Geekbench reinforces this: 1610 single-core and 6551 multi-core. The R20 and R15 results follow the same pattern—711 single/5042 multi and 170 single/1210 multi, respectively. This behavior suggests that the processor is well-suited for applications that rely on a few fast threads, such as legacy productivity suites, some simulation software, and light gaming. Multi-threaded scaling is limited by the six cores, but the high per-core performance compensates in workloads that are not perfectly parallel. The average benchmark score of 3625 reflects a balance that is competitive with the nearest rivals, which have similar aggregate numbers.

Who Should Consider It

The E-2276G is a fit for users who need ECC memory support and a strong single-thread performance in a workstation context. The integrated HD Graphics P630 provides basic display output, which is useful for headless servers or systems that only require a console. For single-thread-bound tasks such as older games, spreadsheet macros, or single-threaded code compilation, the high boost clock and R23 single-core score of 1695 will deliver responsive performance. For multi-threaded creation workloads like video encoding or 3D rendering, the 6-core/12-thread configuration yields a Cinebench R23 multi-core score of 12007, which is adequate for occasional use but not for heavy render farms. The 58th percentile ranking means it outperforms 58% of all CPUs, so it is above average but not a top-tier part. Given its end-of-life status, it is best suited for existing Socket 1151 systems or builds where the platform cost is already sunk.

Platform and Compatibility

The E-2276G uses the Intel Socket 1151 interface and is built on the Coffee Lake architecture. It supports DDR4 memory in a dual-channel configuration with a theoretical bandwidth of 42.7 GB/s. ECC memory is supported, a critical feature for data integrity in workstation and server environments. The CPU provides 16 PCIe Gen 3 lanes from the processor, which is sufficient for a single high-end graphics card or a couple of expansion cards. Integrated HD Graphics P630 handles display output without a discrete GPU. The cache layout includes 64 KB L1 and 256 KB L2 per core, with a 12 MB shared L3. The multiplier is locked, so overclocking is not an option. The production status is end-of-life, meaning no new motherboard support is being added. The 14nm process node and 154 mm² die size are typical of the Coffee Lake generation. The launch MSRP was $362, but the product is no longer in production. For upgrade path, users are limited to the existing Socket 1151 ecosystem; there is no forward compatibility.

Benchmark Performance

The average benchmark score of 3625 places the E-2276G in the 58th percentile. Against its nearest rivals, the deltas are all under half a percent. The Intel Xeon E-2286G scores 3614, a 0.3% deficit. The AMD Ryzen 7 PRO 1700 scores 3613, also 0.3% behind. The AMD Ryzen 7 1700 leads with 3637, a 0.3% advantage. The AMD Ryzen 5 5625U trails by 0.4% with 3610. These differences are statistically insignificant, meaning the E-2276G is effectively tied with all four in aggregate performance. The individual benchmark scores reveal a consistent pattern: single-core results are strong, while multi-core results are moderate. In Cinebench R23, the 1695 single-core score is a standout; the 12007 multi-core score is competitive with the rivals' averages. Geekbench shows 1610 single and 6551 multi. The R20 and R15 tests echo this, with 711/5042 and 170/1210 respectively. The high boost clock of 4.90 GHz drives the single-thread scores, while the six cores limit multi-thread throughput. For users comparing against the listed rivals, the E-2276G offers no clear advantage in either direction; the choice should be based on platform features like ECC and socket compatibility rather than raw performance.
