Intel Core i5-11500H vs Intel Core i7-1265U Comparison

The Intel Core i7-1265U and Intel Core i5-11500H present a compelling contrast in mobile computing, with benchmark data revealing a split personality. The i7-1265U dominates in Cinebench workloads, while the i5-11500H strikes back decisively in Geekbench tests. This analysis examines the numbers to determine which processor holds the advantage in specific scenarios.

Head-to-Head Benchmarks

The Cinebench suite paints a remarkably consistent picture in favor of the Intel Core i7-1265U. Across all six Cinebench tests, the i7-1265U wins with a nearly identical margin of 9.8% in most cases. In Cinebench R23 multicore, the i7-1265U scores 15,549 compared to the i5-11500H’s 14,166, a 9.8% advantage. The single-core results follow the same pattern: the i7-1265U posts 2,195 in Cinebench R23 single-core versus 1,999 for the i5-11500H, again a 9.8% edge. This consistency extends to Cinebench R20, where the i7-1265U leads with 6,530 multicore and 921 single-core, versus 5,949 and 839 for the i5-11500H. Even in the older Cinebench R15 tests, the i7-1265U maintains its lead, scoring 1,567 multicore and 221 single-core, while the i5-11500H manages 1,427 and 201 respectively. Notably, the single-core R15 margin is 10%, slightly higher than the 9.8% seen elsewhere.

The Geekbench results flip the narrative entirely. The Intel Core i5-11500H wins Geekbench multicore with a score of 7,135, while the i7-1265U trails at 5,365. This represents a substantial 24.8% deficit for the i7-1265U, the largest margin in any benchmark category. The Geekbench single-core test also favors the i5-11500H, which scores 1,778 against the i7-1265U’s 1,633, an 8.2% difference. This creates an unusual situation where the i7-1265U wins six of eight head-to-head benchmarks, yet the i5-11500H claims the two Geekbench victories by a combined margin that suggests a fundamentally different performance profile.

The average benchmark scores reflect this competition. The i7-1265U holds an average score of 4,248, while the i5-11500H averages 4,187. That places the i7-1265U just 1.4% ahead of the i5-11500H in the overall data, a razor-thin margin that underscores how the two processors trade blows. Both CPUs sit at the 57th percentile among all CPUs, indicating they occupy similar tiers in the broader market despite their divergent benchmark behaviors.

Where Each One Wins

The Intel Core i7-1265U is the clear winner in rendering and CPU-intensive compute tasks. Its consistent 9.8% lead across all Cinebench R15, R20, and R23 tests—both multicore and single-core—indicates a strong advantage in workloads that rely on sustained processing power. Cinebench is a standard proxy for 3D rendering, video encoding, and other professional content creation tasks. The i7-1265U’s higher boost clock of 4.80 GHz, compared to 4.60 GHz for the i5-11500H, likely contributes to its Cinebench superiority, though the data does not directly confirm causality. The 10-core configuration of the i7-1265U, versus 6 cores on the i5-11500H, may also play a role in multicore Cinebench results.

The Intel Core i5-11500H wins decisively in Geekbench workloads. The 24.8% multicore advantage and 8.2% single-core advantage suggest that Geekbench exercises aspects of the processor that differ from Cinebench. Geekbench includes memory, encryption, and image processing tests, which may favor the i5-11500H’s higher memory bandwidth of 51.2 GB/s—a figure not listed for the i7-1265U. The i5-11500H also has a higher base clock of 2.40 GHz versus 1.80 GHz, which could improve responsiveness in bursty workloads that do not sustain full boost clocks. For users focused on general system performance, web browsing, office productivity, and application launches, the Geekbench results suggest the i5-11500H might feel snappier in real-world use.

The benchmark distribution implies a workload-dependent recommendation. The i7-1265U excels in prolonged compute tasks, while the i5-11500H shines in mixed-use scenarios where Geekbench-style tests dominate. This is not a simple "better" or "worse" comparison; the optimal choice depends entirely on whether the user prioritizes Cinebench-style rendering or Geekbench-style general performance.

Specification Differences

The two processors differ in several fundamental specifications. The Intel Core i7-1265U features 10 cores and 12 threads, while the Intel Core i5-11500H has 6 cores and 12 threads. The i7-1265U has a base clock of 1800 MHz and a boost clock of 4800 MHz; the i5-11500H has a base clock of 2400 MHz and a boost clock of 4600 MHz. The i7-1265U has a TDP of 15 watts, whereas the i5-11500H has a TDP of 35 watts. They use different sockets: the i7-1265U uses Intel BGA 1744, while the i5-11500H uses Intel BGA 1787.

Memory support differs as well. The i7-1265U supports both DDR4 and DDR5 memory, while the i5-11500H supports only DDR4. The i5-11500H lists a memory bandwidth of 51.2 GB/s, while the i7-1265U does not specify a bandwidth figure in the data. Both use dual-channel memory. The integrated graphics differ: the i7-1265U includes Iris Xe 96EU, while the i5-11500H uses UHD Graphics 750. The i5-11500H has a listed die size of 190 mm², while the i7-1265U does not have a die size specified. Both support PCIe Gen 4 with 20 lanes (CPU only), and neither supports ECC memory.

The release dates differ by roughly nine months. The i5-11500H was released on May 10, 2021, while the i7-1265U followed on February 22, 2022. The i5-11500H has a launch MSRP of $250; the i7-1265U has no listed launch MSRP. Neither processor has an unlocked multiplier. The part numbers are SRKT2 for the i5-11500H and SRLFN for the i7-1265U.

Architecture Differences

The architectural split is significant. The Intel Core i7-1265U is based on Alder Lake architecture, specifically the Alder Lake-U codename, and belongs to the Core i7 (Alder Lake-U) generation. The Intel Core i5-11500H uses Tiger Lake architecture, with the Tiger Lake-H codename, and belongs to the Core i5 (Tiger Lake-H) generation. Both are built on a 10 nm process node by Intel, so the manufacturing process is identical.

The core configurations reflect different design philosophies. The i7-1265U’s 10 cores likely include a mix of performance and efficiency cores, a hallmark of Alder Lake’s hybrid architecture, though the data does not specify core types. The i5-11500H’s 6 cores are all performance-oriented, typical of Tiger Lake-H designs. Despite these differences, both processors share the same cache structure: 80 KB of L1 per core, 1.25 MB of L2 per core, and 12 MB of shared L3 cache. This means cache capacity is identical, even though core counts differ.

The integrated graphics also reflect generational differences. The i7-1265U pairs its Alder Lake architecture with Iris Xe 96EU graphics, while the i5-11500H uses UHD Graphics 750. The memory controller differs as well: the i7-1265U supports both DDR4 and DDR5, while the i5-11500H is limited to DDR4. This suggests the newer Alder Lake platform is designed for greater memory flexibility. The i5-11500H’s memory bandwidth of 51.2 GB/s is explicitly listed, while the i7-1265U’s bandwidth is absent, leaving a question about whether the i7-1265U’s DDR5 support enables higher bandwidth in practice.

The Verdict

The data points to a clear performance split. Users who prioritize Cinebench-style rendering tasks—3D modeling, video editing, or CPU rendering—should choose the Intel Core i7-1265U. Its 9.8% advantage across all Cinebench tests, including a 15,549 R23 multicore score versus 14,166 for the i5-11500H, makes it the stronger processor for sustained compute workloads. The higher core count of 10 versus 6 likely contributes to this edge in multicore Cinebench results.

Users who value Geekbench-style general performance should select the Intel Core i5-11500H. Its Geekbench multicore score of 7,135, a 24.8% margin over the i7-1265U’s 5,365, indicates superior performance in memory-intensive and mixed-workload scenarios. The 8.2% single-core Geekbench advantage also suggests better responsiveness in everyday tasks. The i5-11500H’s higher base clock of 2400 MHz, compared to 1800 MHz for the i7-1265U, may explain this advantage in bursty workloads.

The i7-1265U wins six of eight head-to-head benchmarks, yet the i5-11500H’s Geekbench victories are large enough to nearly erase that advantage in the average score. The 1.4% difference in average benchmark scores between the two is negligible, and both sit at the 57th percentile. The decision ultimately rests on the user’s workload. The i7-1265U is the rendering specialist; the i5-11500H is the general-purpose performer. Neither is objectively superior across all metrics, and the data does not support a universal recommendation.
