Intel Core i5-1155G7

The Intel Core i5-1155G7 sits at the absolute midpoint of the database, holding a 50th-percentile ranking among all CPUs. With an average benchmark score of 2387, this Tiger Lake-U mobile processor lands in a dense cluster of competitors, separated from its nearest rivals by margins of roughly one percent or less. The data shows a part that is neither a standout nor a laggard, but rather a benchmark for mainstream mobile performance in its generation.

Benchmark Performance

The Core i5-1155G7’s aggregate score of 2387 places it in a virtual dead heat with its closest competitors. Against the Intel Core i5-8600T, the 1155G7 trails by a razor-thin 0.4%, with the rival posting an average score of 2398. This effectively means the two chips deliver statistically identical throughput in mixed workloads, despite their architectural differences. The margin is so small that real-world application variance would likely overshadow the gap.

Moving to the other side of the ledger, the 1155G7 holds a 0.5% edge over the Intel Core i3-N305, which scores 2376. This is again a negligible difference, but it does indicate that the older Tiger Lake design maintains parity with Intel’s newer Alder Lake-N efficiency silicon. The advantage grows slightly to 0.9% when compared to the AMD Ryzen 3 5300U, which averages 2367. The 1155G7’s largest victory among its nearest rivals is a 1.1% margin over the AMD Ryzen 5 2500X, a desktop part scoring 2361.

These deltas are remarkably small, but the absolute scores tell a more interesting story. In Cinebench R23 multi-core, the 1155G7 produces 8252 points, while its single-core result is 1165. The R20 numbers show 3465 multi-core and 489 single-core. The R15 test yields 831 multi-core and 117 single-core. These figures indicate that the processor’s 4-core, 8-thread configuration is well-tuned for short burst workloads, but the modest core count caps its ceiling in heavily threaded tasks.

Single-Thread vs Multi-Thread Behavior

The split between single-thread and multi-thread performance reveals a processor optimized for responsiveness over raw throughput. In Cinebench R23, the ratio of multi-core to single-core score is approximately 7.1:1, which is typical for a quad-core part with hyper-threading. The single-core score of 1165 in R23 is competitive for the Tiger Lake generation, reflecting the architecture’s strong IPC improvements over older Intel designs.

For the 1155G7, the single-thread strength is the defining characteristic. A score of 489 in Cinebench R20 single-core suggests that day-to-day tasks like web browsing, document editing, and light code compilation will feel snappy. The boost clock of 4.50 GHz, combined with a base clock of 2.50 GHz, allows the processor to ramp up quickly for short-duration tasks. This behavior is ideal for interactive workloads where latency matters more than sustained throughput.

Multi-threaded performance, by contrast, is constrained by the 4-core limit. The R23 multi-core score of 8252 indicates that the processor can handle modern productivity suites and moderate video editing, but it will struggle with prolonged all-core workloads like 3D rendering or batch encoding. The 28W TDP suggests the processor is designed for thin-and-light laptops where thermal headroom is limited, and the multi-thread scores reflect that thermal envelope. The 8 MB of shared L3 cache helps mitigate some multi-thread bottlenecks by reducing memory latency, but it cannot compensate for the lack of physical cores.

Who Should Consider It

The Core i5-1155G7 is best suited for users whose primary workloads are single-thread bound. The strong single-core scores across all Cinebench versions make it a solid choice for office productivity, spreadsheet manipulation, and general web use. The integrated Iris Xe-LP Graphics G7 with 80 execution units provides capable graphics for casual gaming and hardware-accelerated video playback, though the lack of discrete graphics means demanding 3D titles will rely on the iGPU’s limits.

For content creators, the 1155G7 is a mixed proposition. Light photo editing in tools that leverage single-core performance will be smooth, and the 8 MB of shared L3 cache helps with file manipulation. However, video editors working with 4K timelines or effects-heavy projects will find the 4-core limit a bottleneck. The R23 multi-core score of 8252 is adequate for 1080p proxy editing but not for final renders. Users who prioritize sustained all-core performance should look at higher-core-count alternatives, even if those parts score similarly in aggregate benchmarks.

Gamers on a budget will find the 1155G7 acceptable for esports titles and older games, where the single-thread performance and iGPU can hold playable frame rates at lower settings. The processor’s 50th-percentile ranking indicates it is squarely in the middle of the pack, so users should not expect flagship-level performance. For students or professionals needing a portable machine with responsive day-to-day performance, the 1155G7 fits well.

How It Compares

Intel Core i5-8600T: The 8600T edges out the 1155G7 by 0.4%, scoring 2398 versus 2387. This desktop-derived part benefits from six physical cores, but its lower clock speeds and older architecture bring it to parity with the mobile Tiger Lake chip. The 1155G7’s higher boost clock of 4.50 GHz helps close the core-count gap in single-thread tasks.

Intel Core i3-N305: The 1155G7 leads the N305 by 0.5%, with scores of 2387 and 2376 respectively. The N305 is a newer efficiency-focused design, but the 1155G7’s superior single-thread performance and higher peak clocks give it the edge in aggregate benchmarks. The 1155G7 also offers PCIe Gen 4 support, which the N305 lacks in this comparison.

AMD Ryzen 3 5300U: The 1155G7 surpasses the 5300U by 0.9%, scoring 2387 versus 2367. Both are 4-core mobile parts, but the Intel chip’s higher boost clock and Tiger Lake IPC advantage are enough to overcome AMD’s efficiency gains. The 5300U is no slouch, but the data shows the 1155G7 holds a consistent, if small, lead across the tested workloads.

AMD Ryzen 5 2500X: The 1155G7 outperforms the 2500X by 1.1%, with scores of 2387 and 2361. This is notable because the 2500X is a desktop processor with a higher TDP headroom. The 1155G7’s architectural advantages in single-thread performance compensate for the 2500X’s additional cores, resulting in a slight win for the mobile part.
