Intel Core i5-1345U vs Intel Core i7-11600H Comparison

The Intel Core i7-11600H and Intel Core i5-1345U are both mobile processors occupying the same overall tier in the database, each sitting at the 73rd percentile versus all CPUs, yet they arrive there by different routes. The i7-11600H is a Tiger Lake-H part with a 35 W TDP and six cores, while the i5-1345U is a Raptor Lake-U chip with a 15 W TDP and ten cores arranged across performance and efficiency clusters. The recorded data shows a clear split: the i7 dominates sustained multi-core rendering workloads, while the i5 wins several single-thread and scalar tests. Across the head-to-head set, the i7-11600H takes 11 wins against 6 for the i5-1345U.

Head-to-Head Benchmarks

The multi-core story is unambiguous. In Cinebench R23 multi-core, the i7-11600H scores 13286 against 7724 for the i5-1345U, a 72% advantage that stands as the largest gap in the entire dataset. That gap persists across the older Cinebench revisions, though it narrows: R20 multi-core goes to the i7 by 12.9% (5580 versus 4942), and R15 multi-core by only 2.1% (1339 versus 1311). The R15 result suggests that under shorter, burstier loads the i5's hybrid design can nearly match the i7, but as render time lengthens, the i7's higher sustained power budget pulls away decisively.

Single-core results are more mixed than the generation gap might suggest. The i7-11600H wins Cinebench R20 single-core by 12.9% (787 versus 697) and Cinebench R23 single-core by 8.8% (1875 versus 1724). Yet the i5-1345U takes Cinebench R15 single-core with 240 against 188, a 21.7% win for the newer chip, and it leads Passmark single-thread with 3415 against 3019, an 11.6% margin. This inversion is notable: the i5's 4.70 GHz boost clock edges the i7's 4.60 GHz, and in short scalar tests that frequency advantage and newer architecture show through, while in the longer Cinebench R20 and R23 single-core runs the i7's thermal headroom at 35 W keeps it in front.

The Passmark suite mirrors this split. The i7-11600H wins extended instructions by 41% (12938 versus 9178), find prime numbers by 38.3% (65 versus 47), random string sorting by 17.6% (22217 versus 18888), data compression by 16.3% (190721 versus 164005), multithread by 10.9% (16093 versus 14511), and integer math by 4.9% (55437 versus 52847). The i5-1345U counters in three categories: data encryption at 10288 versus 9718 (a 5.5% win), physics at 818 versus 763 (6.7%), and floating point math at 35939 versus 32963 (8.3%). Those floating point and physics wins are interesting given the i7's dominance elsewhere, and they suggest the i5's newer core design has a genuine scalar advantage in certain instruction mixes rather than benefiting purely from burst behavior.

Contextualizing with the rivals recorded in the database, the i7-11600H's average benchmark score of 19921 sits within a fraction of a percent of its nearest competitors: the AMD Ryzen Threadripper PRO 5995WX at 19928 (delta 0%), the Intel Core i7-11800H at 19998 (-0.4%), the AMD EPYC 7713P at 20024 (-0.5%), and the Intel Core i5-11600K at 19786 (0.7%). The i5-1345U's average of 19411 places it similarly close to the Intel Core Ultra 5 226V at 19368 (0.2%), the AMD Ryzen 5 7533HS at 19364 (0.2%), the Intel Core i7-10700F at 19499 (-0.5%), and the Intel Core i7-8700K at 19238 (0.9%). In other words, the aggregate scores differ by only about 2.6% between the two chips, but that average conceals the wide swings in individual tests documented above.

The Verdict

The data supports a straightforward division. For sustained multi-threaded work, rendering, code compilation, encryption-heavy compression tasks, and anything that loads all cores for minutes at a time, the i7-11600H is the stronger choice. The 72% Cinebench R23 multi-core lead and the 41% extended instructions lead are not marginal results; they represent a class of performance the i5-1345U cannot reach within its 15 W envelope. Buyers prioritizing throughput should pick the i7.

The i5-1345U makes its case in a different way. It wins single-thread Passmark by 11.6%, Cinebench R15 single-core by 21.7%, data encryption by 5.5%, physics by 6.7%, and floating point math by 8.3%, all while operating at a 15 W TDP versus the i7's 35 W. For workloads dominated by one or two active threads, responsiveness-oriented tasks, and float-heavy scalar code, the recorded numbers favor the i5. Its newer platform also brings DDR5 memory support and newer integrated graphics, discussed below. Neither chip has an unlocked multiplier, so neither offers overclocking headroom.

Architecture Differences

Both chips are fabbed by Intel on a 10 nm process, but they represent different architectural generations. The i7-11600H uses the Tiger Lake architecture, codenamed Tiger Lake-H, from Intel's 11th Core generation, released on 2021-05-10. The i5-1345U uses the Raptor Lake architecture, codenamed Raptor Lake-U, released on 2023-01-03. The i7's die measures 190 mm²; no die size is recorded for the i5.

The core topology is where the designs diverge most sharply. The i7-11600H uses a homogeneous layout of 6 cores and 12 threads. The i5-1345U has 10 cores but the same 12 threads, consistent with a hybrid performance-plus-efficiency design where the efficiency cores run single-threaded. Both chips carry identical per-core cache figures of 80 KB L1 and 1.25 MB L2, but the i7 holds a larger 18 MB shared L3 versus 12 MB for the i5, an advantage that plausibly contributes to its multi-core rendering results.

Platform features differ as well. The i7 provides 20 CPU PCIe 4.0 lanes against 8 for the i5, a significant connectivity gap for discrete GPUs and fast storage in larger chassis. Memory support splits the two: the i7 handles DDR4 only, while the i5 supports both DDR4 and DDR5, both on dual-channel buses. The i7's recorded memory bandwidth is 51.2 GB/s; no bandwidth figure is recorded for the i5. Integrated graphics also differ, with the i7 pairing UHD Graphics 750 and the i5 pairing Iris Xe Graphics 80EU. Neither chip supports ECC memory.
