Intel Core i5-1335UE vs Intel Core i7-11370H Comparison

The Intel Core i5-1335UE and Intel Core i7-11370H are two mobile processors from different generations, yet benchmark results place them in a remarkably tight contest. The data shows a clear, albeit narrow, advantage for the newer i5-1335UE across all shared test metrics, while the older i7-11370H offers distinct architectural features that may appeal to specific use cases. Both processors sit at the 51st percentile among all CPUs, with average benchmark scores of 2907 and 2861 respectively, indicating that system-level performance will be nearly indistinguishable in many real-world scenarios.

Head-to-Head Benchmarks

The head-to-head comparison is defined by consistency rather than dramatic swings. Across six Cinebench tests, the Intel Core i5-1335UE wins every single one, with margins that hover tightly between 2.2% and 2.7%. The largest victory comes in the Cinebench R23 single-core test, where the i5-1335UE scores 1419 against the i7-11370H’s 1382, a 2.7% lead. This is followed by a 2.6% advantage in four separate tests: Cinebench R15 multi-core (1013 vs 987), R15 single-core (142 vs 139), R20 multi-core (4221 vs 4113), and R20 single-core (595 vs 580). The smallest margin is a 2.2% win in R15 single-core, reinforcing the pattern that the i5-1335UE is consistently slightly faster in both single-threaded and multi-threaded workloads.

These margins are small enough that they would rarely be perceptible in daily use, but they are uniform across every benchmark, suggesting a fundamental efficiency advantage for the Raptor Lake architecture rather than a workload-specific quirk. The i5-1335UE’s multi-core advantage is particularly notable given its 15-watt TDP compared to the i7-11370H’s 28-watt TDP. The i5-1335UE achieves its R23 multi-core score of 10052 while drawing nearly half the power budget, indicating a significant generational improvement in performance-per-watt. The i7-11370H, despite having a higher boost clock of 4.80 GHz versus 4.50 GHz, cannot overcome the i5-1335UE’s superior core count of 10 against 4.

It is also importantly the i7-11370H was benchmarked in additional 3DMark and Geekbench tests not present for the i5-1335UE. Its 3DMark single-thread score of 896 and max-thread score of 3588, along with a Geekbench single-core score of 1667 and multi-core score of 5485, provide a broader performance profile. However, since the i5-1335UE lacks scores for these specific tests, a direct comparison in those workloads is not possible from the available data.

The Verdict

From the data alone, the Intel Core i5-1335UE is the stronger processor. It wins all six head-to-head benchmarks, holds a higher average benchmark score (2907 vs 2861), and achieves this while consuming 15 watts of power compared to the i7-11370H’s 28 watts. For any user prioritizing raw performance, the i5-1335UE is the clear choice, particularly for sustained multi-threaded workloads where its 10 cores and 12 threads provide a structural advantage over the i7-11370H’s 4 cores and 8 threads.

However, the i7-11370H is not without its merits. Its higher base clock of 3.00 GHz (versus 1.30 GHz) suggests better responsiveness in short, bursty tasks that do not allow the i5-1335UE to reach its boost state. It also offers a much larger PCIe lane count (20 lanes versus 8), which could matter for systems with multiple high-bandwidth peripherals. The i7-11370H was launched with a $426 launch MSRP, which is the only pricing data available, but this should not be interpreted as a value recommendation. Ultimately, the i5-1335UE is the better chip for most buyers, while the i7-11370H remains a viable option for niche configurations requiring its specific I/O capabilities.

Architecture Differences

The two processors represent distinct generations of Intel mobile architecture. The i5-1335UE is built on Raptor Lake, specifically the Raptor Lake-U codename, and belongs to the Core i5 generation. The i7-11370H uses the older Tiger Lake architecture, with the Tiger Lake-H codename, and belongs to the Core i7 11th Gen series. Both are fabricated on a 10 nm process node at Intel’s own foundry, but the newer Raptor Lake design clearly extracts more performance from the same lithography.

Core configuration is the most significant architectural divergence. The i5-1335UE offers 10 cores and 12 threads, a hybrid arrangement typical of modern Intel designs, while the i7-11370H is limited to 4 cores and 8 threads. The i5-1335UE compensates for its lower base clock of 1.30 GHz with a boost clock of 4.50 GHz, whereas the i7-11370H starts at 3.00 GHz but boosts slightly higher to 4.80 GHz. Cache hierarchies are identical in structure: both have 80 KB of L1 per core, 1.25 MB of L2 per core, and 12 MB of shared L3. The i7-11370H has a documented die size of 146.1 mm², while the i5-1335UE’s die size is not listed.

Memory support differs meaningfully. The i5-1335UE supports both DDR4 and DDR5 memory, while the i7-11370H is limited to DDR4. Both use a dual-channel memory bus, and the i7-11370H has a listed memory bandwidth of 51.2 GB/s, a figure absent for the i5-1335UE. PCIe connectivity also diverges sharply: the i5-1335UE provides Gen 4 with 8 lanes, while the i7-11370H offers Gen 4 with 20 lanes. The integrated graphics differ as well, with the i5-1335UE featuring Iris Xe Graphics with 80 execution units, while the i7-11370H has Iris XE with 96 execution units, suggesting a potential advantage for the older chip in graphics-heavy tasks without a discrete GPU.

Where Each One Wins

The Intel Core i5-1335UE wins every benchmark where both processors were tested, making its case straightforward. Its 2.6% to 2.7% lead in multi-core tests like Cinebench R23 (10052 vs 9793) and R20 (4221 vs 4113) demonstrates a clear advantage in rendering, video encoding, and other heavily threaded applications. The 10-core, 12-thread configuration is simply better suited to parallel workloads, and the fact that it achieves this at a 15-watt TDP makes it the superior choice for thin-and-light laptops where thermals and battery life are paramount. Its support for DDR5 memory also future-proofs systems against the next generation of memory technology.

The Intel Core i7-11370H, despite losing all head-to-head tests, has specific strengths that the data reveals indirectly. Its higher base clock of 3.00 GHz means it can handle short, single-threaded tasks without needing to ramp up to boost frequencies, potentially offering snappier response in light productivity work. The 96 execution units in its Iris XE graphics versus the 80 in the i5-1335UE suggest better integrated graphics performance, though no direct benchmark is available to confirm this. The 20 PCIe Gen 4 lanes are a decisive advantage for configurations requiring multiple NVMe drives or external GPU enclosures, as the i5-1335UE’s 8 lanes would quickly become a bottleneck. The i7-11370H also has a known die size of 146.1 mm², which may inform thermal design considerations.

Specification Differences

The two processors differ in nearly every key specification category. The i5-1335UE uses the Intel BGA 1744 socket, while the i7-11370H uses the older Intel BGA 1449 socket, confirming their incompatibility with the same motherboards. The i5-1335UE has 10 cores and 12 threads; the i7-11370H has 4 cores and 8 threads. Base clocks are 1.30 GHz versus 3.00 GHz, and boost clocks are 4.50 GHz versus 4.80 GHz, with the i7-11370H holding a 0.30 GHz advantage in peak frequency. The TDP differs by 13 watts, with the i5-1335UE at 15 watts and the i7-11370H at 28 watts.

Memory support is another differentiator: the i5-1335UE accepts DDR4 and DDR5, while the i7-11370H only accepts DDR4. The i7-11370H has a listed memory bandwidth of 51.2 GB/s, a figure not provided for the i5-1335UE. PCIe connectivity favors the i7-11370H with 20 Gen 4 lanes versus 8 Gen 4 lanes for the i5-1335UE. Integrated graphics differ, with the i5-1335UE using Iris Xe Graphics with 80 execution units and the i7-11370H using Iris XE with 96 execution units. The i7-11370H also has a documented die size of 146.1 mm², a launch MSRP of $426, and a part number of SRKH5, none of which are available for the i5-1335UE.
