Intel Core i5-1345UE vs Intel Core i7-11390H Comparison

The Intel Core i7-11390H and Intel Core i5-1345UE are both active mobile processors, but they represent different design philosophies from different eras. The i7-11390H is a 4-core, 8-thread Tiger Lake-H part from 2021, while the i5-1345UE is a 10-core, 12-thread Raptor Lake-U part from 2023. Benchmark data shows that the newer i5-1345UE holds a decisive performance advantage across every tested workload, despite having a significantly lower TDP.

Head-to-Head Benchmarks

The head-to-head data is unambiguous: the Intel Core i5-1345UE wins all six benchmark comparisons, with the i7-11390H trailing by nearly the same margin in every test. In Cinebench R15 multicore, the i5-1345UE scores 940 against the i7-11390H’s 828, a delta of -11.9% for the older chip. The single-core R15 test tells a similar story: 132 for the i5 versus 116 for the i7, again a -12.1% gap. These are not marginal differences; they represent a consistent, roughly 12% deficit for the i7-11390H across the board.

The pattern continues in the newer Cinebench iterations. In Cinebench R20, the i5-1345UE posts 3918 multicore and 553 single-core, while the i7-11390H manages 3451 and 487, respectively. Both deltas sit at -11.9%. The most demanding test, Cinebench R23, shows the i5-1345UE reaching 9329 multicore and 1317 single-core, compared to 8218 and 1160 for the i7-11390H. The multicore gap in R23 is 1111 points, which is substantial for laptops in this class. The consistency of the ~12% delta across both single- and multi-threaded tests suggests the i5-1345UE’s advantage comes from architectural efficiency and clock behavior, not just its higher core count.

Geekbench results were only available for the i7-11390H, which scores 5478 multicore and 1985 single-core. Without a direct i5-1345UE Geekbench number, the Cinebench data must carry the comparison. The i7-11390H’s average benchmark score is 2715, placing it at the 50th percentile of all CPUs. Its nearest rival is the Intel Xeon D-1577 with an identical 2715 average score (0% delta), followed closely by the AMD Ryzen 5 PRO 5650U at 2713 (0.1% ahead) and the Intel Xeon E-2226G at 2709 (0.2% ahead). The i5-1345UE, by contrast, has an average score of 2698, which is slightly lower than the i7-11390H despite winning every head-to-head test.

The i5-1345UE’s nearest rivals include the Intel Core i7-8700T at 2701 (-0.1% delta from the i5) and the Intel Core i7-1185G7E at 2703 (-0.2%). This creates an interesting situation: the i5-1345UE wins every direct benchmark against the i7-11390H, yet its overall average score is dragged down by the missing Geekbench results, which were not tested for the i5. The i7-11390H’s average includes its Geekbench scores, while the i5-1345UE’s average is computed only from Cinebench results. Therefore, the average score comparison is not apples-to-apples; the direct head-to-head Cinebench data is the more reliable indicator.

FAQ

Q: Which processor has a higher single-core score in Cinebench R23?

A: The Intel Core i5-1345UE scores 1317 in Cinebench R23 single-core, which is 12.1% higher than the Intel Core i7-11390H’s 1160.

Q: Does the i5-1345UE’s lower TDP mean it performs worse than the i7-11390H?

A: No. Despite having a 15W TDP compared to the i7-11390H’s 28W, the i5-1345UE wins every head-to-head benchmark, including multicore tests where it scores 9329 versus 8218 in Cinebench R23.

Q: How many cores and threads does each processor have?

A: The i7-11390H has 4 cores and 8 threads, while the i5-1345UE has 10 cores and 12 threads.

Q: What is the difference in boost clock speeds?

A: The i7-11390H boosts up to 5.00 GHz, while the i5-1345UE boosts up to 4.60 GHz. The i5 still wins in single-core performance, indicating its architectural efficiency compensates for the lower clock.

Q: Are both processors on the same manufacturing process?

A: Yes, both are listed as being on a 10 nm process node from Intel.

Q: Which processor supports DDR5 memory?

A: Only the Intel Core i5-1345UE supports DDR5 memory; the i7-11390H is limited to DDR4.

The Verdict

The data overwhelmingly favors the Intel Core i5-1345UE for anyone prioritizing raw performance. It wins all six head-to-head benchmarks, with the i7-11390H trailing by 11.9% to 12.1% in every test. If a user is running Cinebench R23 multicore workloads, the i5-1345UE delivers 9329 points versus 8218, a difference of over 1100 points. Even in single-core tasks, where the i7-11390H’s higher 5.00 GHz boost clock might seem advantageous, the i5-1345UE still comes out ahead with 1317 versus 1160 in R23.

The i7-11390H’s only statistical advantage appears in the average benchmark score (2715 versus 2698), but this is misleading because the i5-1345UE lacks Geekbench results in the data. When comparing only the tests where both processors have scores, the i5-1345UE is the clear winner. Users should choose the i5-1345UE if they need better multi-threaded performance from its 10 cores and 12 threads, or if they want the lower 15W TDP for fanless or ultra-portable designs. The i7-11390H remains a viable choice for systems requiring its specific BGA 1449 socket or its 20 PCIe Gen 4 lanes, but on pure benchmark merit, it is the weaker processor.

Specification Differences

The two processors diverge on several key specifications. The i7-11390H uses the Intel BGA 1449 socket, while the i5-1345UE uses the newer Intel BGA 1744 socket. Core counts differ significantly: the i7 has 4 cores and 8 threads, whereas the i5 has 10 cores and 12 threads. Base clocks are drastically different, with the i7 running at 2.90 GHz and the i5 at a stated 1400.00 MHz, though the i5’s boost clock of 4.60 GHz approaches the i7’s 5.00 GHz. The i7 has a higher TDP of 28W, while the i5 is rated at 15W.

Memory support also varies. The i7-11390H only supports DDR4, while the i5-1345UE supports both DDR4 and DDR5. The i7 has a rated memory bandwidth of 51.2 GB/s, whereas the i5’s memory bandwidth is not listed. PCIe lanes differ as well: the i7 offers Gen 4 with 20 lanes (CPU only), while the i5 offers Gen 4 with 8 lanes (CPU only). Integrated graphics are different too: the i7 has Iris Xe Graphics with 96 execution units, while the i5 has Iris Xe Graphics with 80 execution units.

Architecture Differences

Architecturally, these are products from different generations. The i7-11390H is based on Tiger Lake, specifically the Tiger Lake-H codename, and belongs to the Core i7 (Tiger Lake-H) generation. The i5-1345UE is based on Raptor Lake, with a Raptor Lake-U codename and a Core i5 (Raptor Lake-U) generation. Both use a 10 nm process node from Intel, and both have identical cache layouts: 80 KB of L1 per core, 1.25 MB of L2 per core, and 12 MB of shared L3.

The die size is known only for the i7-11390H at 146.1 mm²; the i5-1345UE’s die size is not listed. The i7 was released on 2021-06-20, while the i5 was released on 2023-01-03. The i7 has a listed part number (SRKSL) and a launch MSRP of $426, while the i5 has neither a part number nor a launch MSRP in the data. Neither processor has an unlocked multiplier, and both are listed as active in production and targeting the mobile market segment. The i5-1345UE’s support for DDR5 memory is a notable architectural advancement over the i7-11390H, which is limited to DDR4, potentially offering higher memory bandwidth in systems that pair it with DDR5 modules.
