Intel Core i5-1155G7 (IPU)

Intel Core i5-1155G7 (IPU) is a 4-core, 8-thread mobile processor built on Intel’s Tiger Lake-U architecture and 10 nm process. It belongs to the Core i5 generation (Willow Cove-U) and is designed for thin-and-light laptops, with a base clock of 2.50 GHz, a boost clock of 4.50 GHz, and a 28 W TDP. The chip integrates Iris Xe-LP Graphics G7 with 80 execution units, and its 8 MB shared L3 cache, dual-channel memory controller, and PCIe Gen 4 support (4 CPU lanes) define its platform positioning. Below, the analysis covers platform fit, target workloads, rival positioning, and benchmark-derived performance, based solely on the provided data.

Platform and Compatibility

The Intel Core i5-1155G7 uses the Intel BGA 1449 socket, which is a soldered, non-upgradeable mobile package. This means the processor is permanently attached to the motherboard, and end users cannot swap it for a different CPU. The platform is built around Tiger Lake-U, which targets ultra-portable notebooks rather than desktop or high-performance mobile workstations. The 10 nm process node and 144 mm² die size indicate a compact, power-efficient design, consistent with its 28 W TDP classification.

Memory support includes DDR4 and LPDDR4X, both running in dual-channel mode. The absence of ECC memory support confirms a consumer-oriented design, not a server or workstation part. PCIe support is limited to Gen 4 with 4 lanes available from the CPU, which is a modest allocation for connecting discrete GPUs or high-speed NVMe storage. In practice, this lane count suits a single primary expansion device or a fast SSD, but it does not provide the multi-device bandwidth of desktop or high-core-count platforms.

The integrated graphics solution is Iris Xe-LP Graphics G7 with 80 execution units. This is a significant part of the platform, as it eliminates the need for a discrete GPU in many everyday and light-creative workloads. The production status is listed as Active, and the release date is 2021-05-30, with a launch MSRP of $309. The processor is not multiplier-unlocked, so overclocking is not supported. For upgrade path, the BGA 1449 socket means no CPU upgrades are possible; the entire laptop or motherboard must be replaced for a faster processor. The platform is therefore best suited for users who buy a complete system and do not plan to modify it.

Who Should Consider It

Based on the available benchmark data, the Core i5-1155G7 sits at the 50th percentile of all CPUs, which indicates it performs near the median of the entire CPU landscape. For a mobile 4-core part, this is a reasonable mid-range position. Users who should consider this processor include those running office productivity suites, web browsing, and light multitasking, where the 8 threads and 4.50 GHz boost clock provide responsive single-threaded performance. The integrated Iris Xe graphics also makes the chip suitable for casual gaming at lower settings, though no specific frame-rate data is available.

For content creation, the 4-core/8-thread configuration can handle photo editing and light video rendering, but the 50th percentile score suggests it will not excel in heavily threaded workloads compared to higher-core-count rivals. The 8 MB shared L3 cache helps with data reuse, but it is not a substitute for more cores. Users with heavy 3D rendering or complex simulation tasks should look elsewhere, as the data does not support strong multi-threaded throughput. Conversely, for users who prioritize portability and battery life over raw compute, the 28 W TDP and 10 nm process make this a balanced choice for everyday laptops.

The chip is not suited for enthusiasts or overclockers, given the locked multiplier and soldered socket. It also lacks ECC memory, so it is not appropriate for error-sensitive server or scientific workloads. Overall, the target audience is mainstream mobile users who need a dependable CPU for work, school, and media consumption, with occasional light creative tasks.

How It Compares

The FACT PACK includes no entries for nearestRivals, so no direct rival comparisons with names, scores, or deltaPct values are available. Consequently, the analysis below is limited to the processor’s absolute benchmark position and cannot reference specific competitor products. The 50th percentile score places it exactly in the middle of all tested CPUs, meaning half of all processors score higher and half score lower. Without rival data, it is impossible to state whether it is faster or slower than any particular model.

Given the absence of rival information, the only quantitative comparison possible is against the broader CPU distribution. A 50th percentile rank implies that the Core i5-1155G7 delivers median performance, which is adequate for typical mobile use but not exceptional. For instance, a processor at the 75th percentile would be significantly faster in synthetic benchmarks, while a 25th percentile part would be noticeably slower. The chip’s 4-core design and 28 W TDP are consistent with this mid-pack positioning.

It is important to note that the avgBenchmarkScore field is 0, and the benchmarks array is empty, so no absolute score can be cited. The lack of rival data means all comparative statements must be qualitative, referencing the percentile rank only. Users should interpret the 50th percentile as a neutral starting point: the processor will handle everyday tasks without issue, but it will not break any performance records in multi-threaded applications.

A: The launch MSRP is $309, as stated in the FACT PACK.

Benchmark Performance

The benchmark data for the Intel Core i5-1155G7 is sparse: the benchmarks array is empty, the avgBenchmarkScore is 0, and the nearestRivals list is empty. The only quantitative performance indicator is the percentileVsAllCpus value of 50, which places the chip at the exact midpoint of all CPUs in the database. This means that 50% of all processors scored higher and 50% scored lower, a neutral ranking that suggests balanced, mainstream performance.

In the absence of rival-specific scores and delta percentages, the analysis must rely on architectural context. With 4 cores and 8 threads, the chip can handle single-threaded tasks well, especially given the 4.50 GHz boost clock. The 8 MB shared L3 cache is modest but adequate for a quad-core design, and the 10 nm process helps with power efficiency at the 28 W TDP. The integrated Iris Xe graphics with 80 EUs is a notable strength, likely providing better iGPU performance than older Intel solutions, though no comparative numbers are available.

For multi-threaded workloads, the 4-core limit is the primary constraint. Compared to a hypothetical 6-core or 8-core rival, the 1155G7 would likely trail by a significant margin, but without deltaPct values, no exact percentage can be stated. The 50th percentile rank implies that many higher-core-count mobile chips outperform it, but also that many lower-end parts fall behind. Users should expect smooth performance in everyday applications, but for heavy rendering or encoding, the chip will not compete with higher-tier mobile processors.

The absence of a benchmark score (0) is unusual and suggests that no standardized test results were recorded for this specific part in the database. Therefore, all performance interpretations are based on the percentile rank and the architectural specifications. The 50th percentile is a solid, unremarkable position: it is not a high-performance part, but it is also not a budget-level chip. For a mainstream laptop CPU launched in 2021, this aligns with expectations, though the data does not allow for more precise rival comparisons.
