Intel Core i5-1345UE vs Intel Core i7-1365UE Comparison

The Intel Core i5-1345UE and Intel Core i7-1365UE are two mobile processors from Intel’s Raptor Lake-U family, both designed for the same 15 W thermal envelope and BGA 1744 socket. Despite the i7’s higher tier name, the benchmark data reveals a surprising outcome: the i5-1345UE wins every single head-to-head test, albeit by very narrow margins. The i7-1365UE does post higher base and boost clock speeds, yet this does not translate into a performance advantage in the Cinebench suite. This analysis will dissect the architectural similarities, benchmark results, and specification differences to determine what each processor actually offers.

Q: Do both processors use the same integrated graphics?

A: Yes, both the i5-1345UE and i7-1365UE feature Iris Xe Graphics with 80 execution units.

Architecture Differences

Both processors are built on the same fundamental architecture, which explains their similar performance profiles. They share the Raptor Lake architecture and the Raptor Lake-U codename, and both are fabricated on Intel’s 10 nm process node. The core and thread counts are identical at 10 cores and 12 threads, and the cache hierarchy is exactly the same: 80 KB of L1 per core, 1.25 MB of L2 per core, and a shared 12 MB L3 cache.

The only notable architectural differences are in the clock speeds. The i7-1365UE has a 300 MHz higher base clock (1700 MHz vs 1400 MHz) and a 300 MHz higher boost clock (4.90 GHz vs 4.60 GHz). This suggests the i7 is binned to run at higher frequencies, potentially offering better transient performance in short bursts. However, the benchmark results indicate that this frequency advantage does not manifest as a sustained performance lead in multi-threaded or single-threaded Cinebench workloads. The memory support (DDR4, DDR5), PCIe configuration (Gen 4, 8 Lanes), and integrated graphics (Iris Xe 80EU) are all identical between the two.

Head-to-Head Benchmarks

The head-to-head data is remarkably one-sided. Across all six Cinebench tests, the Intel Core i5-1345UE emerges as the winner, but the margins are consistently narrow, ranging from 0.8% to 0.9%. This suggests that the two processors are effectively performance equals in practice, with the i5 holding a slight, consistent edge.

In the Cinebench R15 multi-core test, the i5-1345UE scores 940 against the i7-1365UE’s 932, a 0.9% difference. The single-core R15 test shows a similar pattern: 132 for the i5 versus 131 for the i7, a 0.8% lead. Moving to Cinebench R20, the multi-core scores are 3918 for the i5 and 3887 for the i7, again a 0.8% delta. The R20 single-core test has the i5 at 553 and the i7 at 548, a 0.9% gap.

The most demanding test, Cinebench R23, reinforces the trend. The i5-1345UE scores 9329 in multi-core, while the i7-1365UE scores 9257, a 0.8% advantage. In the R23 single-core test, the i5 leads with 1317 versus 1306, another 0.8% margin. The data shows a consistent pattern: the i5-1345UE is marginally faster in every workload, but the differences are so small (under 1%) that they would be imperceptible in real-world use. The i7’s higher clock speeds do not translate into a win, suggesting that the i5’s silicon may have better thermal characteristics or that the i7’s frequency advantage is offset by other factors in these specific tests.

The Verdict

Based strictly on the benchmark data, the Intel Core i5-1345UE is the superior processor. It wins all six head-to-head tests and has a higher average benchmark score (2698 vs 2677). The i5 also sits at the 50th percentile of all CPUs, and its nearest rivals include the Intel Core i7-8700T (average score 2701, delta -0.1%) and the Intel Core i7-1185G7E (average score 2703, delta -0.2%). The i7-1365UE also sits at the 50th percentile, but its nearest rivals are slightly slower, including the Intel Core i5-9500F (average score 2670, delta 0.3%) and the Intel Core i7-9700T (average score 2668, delta 0.4%).

For a user choosing between these two, the data points clearly to the i5-1345UE. It offers a slight performance advantage in every benchmark measured, despite having a lower tier name and lower clock speeds. The i7-1365UE’s higher base and boost clocks do not provide any benefit in these tests. Unless external factors (such as specific platform features not listed in this data) favor the i7, the i5-1345UE is the rational choice based on the Cinebench scores alone.

Specification Differences

The primary differences between the two processors are confined to clock speeds and the resulting performance metrics. Both chips share the same core configuration, cache, memory support, and integrated graphics.

• Base Clock: The i5-1345UE runs at 1400 MHz, while the i7-1365UE runs at 1700 MHz. The i7 has a 300 MHz higher base frequency.
• Boost Clock: The i5-1345UE boosts up to 4.60 GHz, while the i7-1365UE boosts up to 4.90 GHz. The i7 has a 300 MHz higher boost frequency.
• Average Benchmark Score: The i5-1345UE averages 2698, while the i7-1365UE averages 2677. The i5 is ahead by 21 points.
• Head-to-Head Wins: The i5-1345UE wins 6 benchmarks, while the i7-1365UE wins 0.

All other specifications are identical: 10 nm process, 10 cores, 12 threads, 12 MB L3 cache, DDR4/DDR5 memory support, dual-channel memory bus, PCIe Gen 4 with 8 lanes, Iris Xe Graphics 80EU, and a 15 W TDP.

Where Each One Wins

Based on the benchmark results, the Intel Core i5-1345UE wins in every single category of the Cinebench suite. It holds a slight edge in both single-core and multi-core workloads. The i5-1345UE is the better choice for users who want the highest possible Cinebench scores, as it wins the R15, R20, and R23 tests in both single-threaded and multi-threaded modes.

The Intel Core i7-1365UE, however, does not win any benchmark tests in this dataset. Its only advantages are its higher base and boost clock specifications. In theory, these higher clocks could benefit workloads that are extremely short and bursty, but the Cinebench data does not show any such advantage.

In practical terms, the performance difference between the two is so small (under 1% in all tests) that it is likely negligible for most applications. The i5-1345UE is the data-backed winner for users prioritizing raw benchmark performance. The i7-1365UE might be considered if a system integrator offers it at a similar price point and the higher clock speeds are seen as a potential benefit for specific, non-benchmarked tasks, but the benchmark evidence does not support a performance advantage for the i7. The choice, based on this data, is clearly the i5-1345UE.
