Intel Core i5-1345UE vs Intel Core i7-1185G7E Comparison

The Intel Core i7-1185G7E and the Intel Core i5-1345UE are both 15-watt mobile processors, but they target very different points in the performance spectrum despite landing at the same overall percentile ranking. The data shows a clear sweep: the i5-1345UE wins all six head-to-head benchmarks, with margins ranging from 10.6% to 11.1%. However, the average benchmark scores tell a tighter story — the i7-1185G7E averages 2703, while the i5-1345UE averages 2698, placing them within 0.2% of each other. This discrepancy between the Cinebench results and the aggregate score is worth unpacking, as it highlights how different workloads reward different architectures.

Head-to-Head Benchmarks

The i5-1345UE takes every benchmark in the comparison, and the margins are remarkably consistent. In Cinebench R15 multicore, the i5-1345UE scores 940 against the i7-1185G7E’s 836, a delta of -11.1% for the older chip. Single-core R15 shows a similar pattern: 132 versus 118, a 10.6% advantage for the i5-1345UE. Moving to Cinebench R20, the multicore gap is 3918 versus 3487, an 11% difference, and single-core is 553 versus 492, also 11%. The newest test, Cinebench R23, repeats the trend: multicore 9329 versus 8303, and single-core 1317 versus 1172, both showing an 11% lead for the i5-1345UE.

The consistency of the deltaPct — hovering between 10.6% and 11.1% across all six tests — suggests this is not a workload-specific advantage but a fundamental performance gap. The i5-1345UE’s single-core advantage is particularly notable because both chips share the same 10nm process node and similar L3 cache. The 11% single-core lead in R23 (1317 vs 1172) indicates the newer Raptor Lake architecture extracts more instructions per clock than Tiger Lake, even at a lower base clock of 1.40 GHz versus 1.80 GHz.

Interestingly, the average benchmark score pools these results with Geekbench data, where the i7-1185G7E posts 5459 multicore and 1756 single-core. That Geekbench performance is strong enough to bring the i7-1185G7E’s average to 2703, slightly above the i5-1345UE’s 2698. This means the i7-1185G7E compensates for its Cinebench deficit in other synthetic workloads, likely due to its higher boost clock of 4.40 GHz compared to the i5-1345UE’s 4.60 GHz — though the latter still wins in Cinebench.

Architecture Differences

The two processors come from different generations and microarchitectures. The i7-1185G7E is built on Tiger Lake-U, part of the Willow Cove-U core family, while the i5-1345UE uses Raptor Lake-U. Both are fabricated on Intel’s 10nm process node, so the performance gap cannot be attributed to lithography improvements. The core counts differ significantly: the i7-1185G7E has 4 cores and 8 threads, while the i5-1345UE has 10 cores and 12 threads. This hybrid configuration likely uses a mix of performance and efficiency cores, which explains the multicore advantage in Cinebench despite the lower base clock.

Cache configurations are identical in structure: 80 KB of L1 per core, 1.25 MB of L2 per core, and 12 MB of shared L3. The die size is only listed for the i7-1185G7E at 144 mm², while the i5-1345UE’s die size is not provided. Memory support differs — the i7-1185G7E supports DDR4 and LPDDR4X, while the i5-1345UE supports DDR4 and DDR5. Both use dual-channel memory buses, and neither supports ECC memory.

PCIe lanes are a notable difference: the i7-1185G7E provides 4 CPU-only Gen 4 lanes, while the i5-1345UE doubles that to 8 lanes. Integrated graphics also differ, with the i7-1185G7E featuring Iris Xe-LP Graphics G7 with 96 execution units, while the i5-1345UE has Iris Xe Graphics with 80 execution units. The i7-1185G7E uses the Intel BGA 1449 socket, while the i5-1345UE uses the newer Intel BGA 1744 socket, meaning they are not interchangeable in motherboards.

The Verdict

The benchmark data is unambiguous: the Intel Core i5-1345UE wins every Cinebench test, from R15 through R23, in both single-core and multicore workloads. The i7-1185G7E’s only claim to parity comes from its Geekbench scores, which are not included in the head-to-head table but contribute to its average benchmark score of 2703 versus the i5-1345UE’s 2698. For anyone prioritizing raw rendering performance or CPU-bound tasks, the i5-1345UE is the clear choice, offering 11% better scores across the board.

However, the i7-1185G7E is not without merit. Its higher base clock of 1.80 GHz and older Willow Cove architecture still deliver competitive Geekbench results, and its 96EU integrated graphics outclass the 80EU unit in the i5-1345UE. The i7-1185G7E also has a formal launch MSRP of $431, while the i5-1345UE’s launch MSRP is not listed. If the workload relies on Geekbench-style tasks or benefits from stronger integrated graphics, the i7-1185G7E remains viable, but the i5-1345UE’s consistent Cinebench dominance makes it the better all-rounder for multi-threaded applications.

Where Each One Wins

The i5-1345UE wins every benchmark in the head-to-head comparison, but the margins matter. In Cinebench R15 multicore, it leads by 104 points (940 vs 836), and in R23 multicore, the gap grows to 1026 points (9329 vs 8303). This makes it the superior choice for video rendering, 3D modeling, or any task that scales across multiple cores. Its 10 cores and 12 threads provide a structural advantage over the 4-core, 8-thread i7-1185G7E, and the 11% single-core lead in R23 (1317 vs 1172) shows it also handles lightly-threaded tasks faster.

The i7-1185G7E’s wins are more subtle. Its average benchmark score of 2703 edges out the i5-1345UE’s 2698, a 0.2% difference that comes from Geekbench results not shown in the head-to-head table. For users whose software relies on Geekbench-style synthetic tests, the i7-1185G7E is competitive. Additionally, its 96EU integrated graphics unit is superior to the 80EU unit in the i5-1345UE, making it a better fit for light gaming or GPU-accelerated workloads without a discrete card. The 4 PCIe Gen 4 lanes on the i7-1185G7E versus 8 on the i5-1345UE also matters for expandability, where the newer chip offers more bandwidth for NVMe storage or other peripherals.

In practical terms, the i5-1345UE is the performance pick for almost any CPU-bound scenario, while the i7-1185G7E holds value in systems where integrated graphics quality and Geekbench performance are priorities. The data does not support choosing the i7-1185G7E for Cinebench workloads, but its equal average score and stronger iGPU keep it from being obsolete.
