Intel Core i5-11260H vs Intel Xeon E-2286M Comparison

Head-to-Head Benchmarks

The head-to-head results between the Intel Xeon E-2286M and the Intel Core i5-11260H are surprisingly lopsided in one direction, yet the single decisive victory for the Xeon is the most significant gap in the entire comparison. Across seven of eight recorded benchmarks, the Core i5-11260H takes the win, but the margins are razor-thin. In Cinebench R15 multi-core, the i5 scores 1300 against the Xeon's 1295, a delta of just -0.4%. The single-core R15 test shows the same pattern: 183 versus 182, a -0.5% difference. Cinebench R20 multi-core repeats the story with 5420 versus 5396 (-0.4%), and R20 single-core gives 764 versus 761 (-0.4%). Cinebench R23 multi-core has the i5 at 12905 against 12848 (-0.4%), while R23 single-core shows 1821 versus 1813 (-0.4%). These are essentially statistical ties, with the i5 consistently edging ahead by less than half a percentage point.

The single exception is Geekbench multi-core, where the Xeon E-2286M decisively wins with 6746 points against the i5's 5780, a massive 16.7% advantage. That is the largest delta in either direction across the entire benchmark suite. The Geekbench single-core result flips back to the i5, though by a more modest margin: 1595 versus 1537, a -3.6% difference. So the data shows a clear split: the i5 wins every Cinebench test and Geekbench single-core by tiny margins, while the Xeon dominates Geekbench multi-core by a wide gap. The overall win count is 7 for the i5 and 1 for the Xeon, but the magnitude of that single Xeon victory carries real weight for certain workloads.

What these numbers mean in practice is that for most everyday threaded tasks, the two processors are effectively interchangeable. A 0.4% difference in Cinebench scores is well within run-to-run variance and will not be perceptible in real-world use. The Geekbench multi-core result, however, suggests that the Xeon's architecture handles certain multi-threaded workloads substantially better, likely due to its higher core count and server-oriented design. The i5 counters with a 3.6% lead in Geekbench single-core, indicating better per-thread performance in that specific test, which aligns with its newer microarchitecture.

Architecture Differences

The two chips come from different eras and design philosophies. The Intel Xeon E-2286M belongs to the Xeon E-2200 series, built on the Coffee Lake architecture with a 14 nm process node. It features 8 cores and 16 threads, with a base clock of 2.40 GHz and a boost clock of 5.00 GHz. The die size is 180 mm², and the L3 cache is 16 MB shared. Memory support is DDR4 with a dual-channel bus and 42.7 GB/s bandwidth, and it supports ECC memory, a hallmark of workstation-class parts. The integrated graphics are UHD Graphics P630, and the socket is Intel BGA 1440.

The Intel Core i5-11260H is from the Core 11th Gen series, built on the Tiger Lake architecture with a 10 nm process node. It has 6 cores and 12 threads, with a base clock of 2.10 GHz and a boost clock of 4.40 GHz. The die size is 190 mm², slightly larger than the Xeon despite fewer cores. The L1 cache is 80 KB per core versus the Xeon's 64 KB per core, and the L2 cache is 1.25 MB per core versus 256 KB per core, a substantial per-core increase. The L3 cache is 12 MB shared, smaller than the Xeon's 16 MB. Memory support is DDR4 with a dual-channel bus and 51.2 GB/s bandwidth, higher than the Xeon, but it does not support ECC. The integrated graphics are simply UHD Graphics (non-P630 branding), and the socket is Intel BGA 1787.

The process node difference is notable: 14 nm versus 10 nm. The newer 10 nm process allows the i5 to achieve competitive performance with fewer cores and lower power. The Xeon's TDP is 45 W, while the i5's is 35 W, meaning the i5 delivers similar multi-core Cinebench scores while drawing less power. PCIe support also differs: the Xeon offers Gen 3 with 16 lanes (CPU only), while the i5 offers Gen 4 with 20 lanes (CPU only), giving the newer chip more bandwidth and more lanes for expansion. The Xeon's market segment is Server/Workstation, and its production status is End-of-life, released on 2019-05-28. The i5 is classified as Mobile, remains Active in production, and was released on 2021-05-10. Both have locked multipliers, so neither supports overclocking.

The Verdict

The data points to a clear but nuanced recommendation. The Intel Core i5-11260H wins 7 of 8 head-to-head benchmarks, including every Cinebench test, and does so while drawing less power (35 W TDP versus 45 W) and using a newer 10 nm process. It also offers PCIe Gen 4 with 20 lanes, higher memory bandwidth (51.2 GB/s versus 42.7 GB/s), and remains in active production. For most users, particularly those building a mobile workstation or a compact system where power efficiency and modern connectivity matter, the i5-11260H is the stronger choice. Its per-core cache configuration (80 KB L1 and 1.25 MB L2 per core) gives it excellent single-threaded responsiveness, as reflected in its Geekbench single-core lead of 3.6%.

However, the Xeon E-2286M is not without its own case. Its 16.7% lead in Geekbench multi-core is the largest margin in any test, and it offers 8 cores versus 6, 16 threads versus 12, and a higher boost clock of 5.00 GHz versus 4.40 GHz. It also supports ECC memory, which is a non-negotiable feature for certain server or workstation environments where data integrity is paramount. The Xeon's larger 16 MB L3 cache and its Server/Workstation market segment signal that it was designed for sustained, reliable multi-threaded throughput. If your workload is heavily reliant on the specific multi-threaded patterns that Geekbench measures, the Xeon's advantage is substantial. But for general productivity, content creation, and mixed workloads, the i5's consistent, if marginal, wins across Cinebench and its single-core advantage make it the more versatile processor. The Xeon is end-of-life, while the i5 is active, which also factors into long-term availability and support.

Where Each One Wins

The Intel Core i5-11260H wins in every Cinebench generation tested: R15 multi-core, R15 single-core, R20 multi-core, R20 single-core, R23 multi-core, and R23 single-core. It also wins Geekbench single-core. These victories are consistent but small, all within -0.4% to -3.6% deltas. The i5 is also the winner on efficiency metrics, with a 10 W lower TDP, and offers a newer process node, higher memory bandwidth, and more PCIe lanes with Gen 4 support. For users who prioritize single-threaded responsiveness, modern platform features, and lower power draw, the i5 is the clear pick. Its active production status means easier sourcing for new builds.

The Intel Xeon E-2286M wins Geekbench multi-core by a decisive 16.7%, the largest margin in the entire comparison. It also holds advantages in core count (8 versus 6), thread count (16 versus 12), boost clock (5.00 GHz versus 4.40 GHz), base clock (2.40 GHz versus 2.10 GHz), and L3 cache size (16 MB versus 12 MB). It supports ECC memory, which the i5 does not, and it carries a 45 W TDP, higher than the i5 but justified for a workstation-class part. For server or workstation deployments where ECC is required, or for multi-threaded workloads that align with Geekbench's test patterns, the Xeon's 16.7% lead is a substantial advantage that outweighs its losses elsewhere. Its end-of-life status and higher launch MSRP of $623 (versus $250 for the i5) reflect its different market positioning, but the recorded data shows it remains competitive in its niche.
