Intel Core i5-1135G7 (IPU)

The Intel Core i5-1135G7 (IPU) is a mobile processor from Intel’s Tiger Lake-U family, built on a 10 nm process and designed for thin-and-light laptops. It packs 4 cores and 8 threads, with a base clock of 1.50 GHz and a boost clock of 4.20 GHz. The chip carries a TDP of 15 W, a dual-channel memory controller for DDR4 and LPDDR4X, and an integrated Iris Xe Graphics G7 with 80 execution units. In the database, it sits at the 50th percentile across all CPUs, meaning it is a median performer — neither a standout nor a laggard. This analysis draws exclusively from the specification sheet and the percentile placement, since individual benchmark scores are not recorded for this part.

Benchmark Performance

The most striking data point for the i5-1135G7 is its percentile placement: exactly the 50th percentile across all CPUs in the database. This indicates that, in aggregate, it outperforms half of all processors and is outperformed by the other half. For a mobile part with a 15 W TDP, that is a notable position — it suggests that the chip delivers competitive performance within its power envelope, but it does not reach the heights of higher-core-count desktop or high-performance mobile parts. Without explicit benchmark scores, we must infer performance from the architecture: a 4-core/8-thread configuration with a 4.20 GHz boost clock. The boost clock is unusually high for a 15 W part, implying that short single-thread bursts can be very fast, which is typical of Intel’s “Willow Cove” cores used in Tiger Lake. The lack of benchmark scores in the database is a limitation, but the percentile figure offers a reliable anchor for positioning.

The absence of nearestRivals data means we cannot cite specific percentage deltas against competing CPUs. However, the 50th percentile alone tells us that the i5-1135G7 is not a low-end part; it sits squarely in the middle of the performance distribution. For context, many older desktop CPUs with higher TDPs may fall below this percentile, while modern high-core-count parts will rank above. The chip’s 8 MB of shared L3 cache is modest by today’s standards, but the per-core L2 cache of 1.25 MB is generous and can help reduce latency for frequently accessed data. The 144 mm² die size, fabricated on Intel’s 10 nm node, is a reasonable compromise between transistor density and cost, though the process is not cutting-edge by 2025 standards.

Single-Thread vs Multi-Thread Behavior

The i5-1135G7 presents a clear split between single-thread and multi-thread capability. With a base clock of 1.50 GHz and a boost clock of 4.20 GHz, the ratio is 2.8x — a large gap that indicates aggressive turbo behavior. In single-threaded workloads, the CPU can ramp up to 4.20 GHz for short bursts, which is excellent for tasks like web browsing, office document editing, and light coding. The 4 cores and 8 threads provide a baseline for multi-threaded work, but the relatively low base clock means sustained all-core loads will likely run at lower frequencies, depending on thermal and power limits. The 15 W TDP is the governing constraint: when all cores are active, the processor must balance frequency against heat. The result is that multi-threaded performance is adequate but not exceptional, while single-thread responsiveness is a clear strength.

The cache hierarchy supports this behavior. The L1 cache is 80 KB per core, which is typical for Intel’s recent architectures, and the L2 cache at 1.25 MB per core is on the higher side, helping to feed the cores during bursty single-thread operations. The shared 8 MB L3 cache is a moderate pool that can benefit multi-threaded workloads by reducing memory traffic, but it is not as large as what you would find in desktop parts. For real-world use, this split means that the i5-1135G7 excels in interactive tasks where a single core does most of the work — think of spreadsheet recalculation, browser rendering, or light photo editing — while it will handle multi-threaded compilation or video encoding with less grace, though still functionally.

Who Should Consider It

Given its mobile segment, 15 W TDP, and integrated graphics, the i5-1135G7 is aimed at ultraportable laptops where battery life and low heat are priorities. The data suggests it is a good fit for office productivity: the high boost clock ensures snappy response in word processors, email clients, and presentation software. The 8 threads allow for moderate multitasking — running a few browser tabs, a music player, and a chat application simultaneously will not strain the CPU. For content creation, the picture is more nuanced. Light photo editing in tools like Photoshop or GIMP will benefit from the strong single-thread performance and the integrated Iris Xe Graphics, which has 80 execution units — a capable iGPU for basic acceleration. Video editing, however, is likely to be a struggle due to the limited core count and the 15 W power envelope; 4K rendering or heavy effects will cause the CPU to throttle. Gaming is a mixed bag: the i5-1135G7 can handle older or less demanding titles at lower settings, but modern AAA games will be bottlenecked by both the CPU and the integrated GPU. The 50th percentile placement reinforces that this is a mainstream, not enthusiast, processor.

The chip is end-of-life, so it is only relevant for existing laptops or second-hand systems. Buyers looking for a new machine should be aware that this part is from 2020 and may not support the latest software optimizations. However, for a budget-conscious user who already owns a laptop with this CPU, the performance is sufficient for everyday tasks. The launch MSRP was $309, though that is not an indicator of current value.

FAQ

How It Compares

The database lists no specific nearest rivals for the i5-1135G7, so we cannot provide direct percentage deltas against named competitors. However, the 50th percentile placement offers a useful reference. This chip sits exactly at the median of all CPUs in the database, meaning it is neither a low-budget part nor a high-performance flagship. In practical terms, it will be outperformed by most desktop CPUs with 6 or more cores, and by many newer mobile parts that have higher core counts or more modern architectures. On the other hand, it will outpace many older dual-core mobile processors and some entry-level desktop chips. The lack of rival data is a gap, but the percentile alone tells us that the i5-1135G7 is a mid-tier mobile processor that strikes a balance between power efficiency and responsiveness.

Platform and Compatibility

The i5-1135G7 is built on the Tiger Lake-U architecture and uses the Intel BGA 1449 socket. This socket is exclusive to mobile platforms, and the CPU is permanently soldered to the motherboard, meaning there is no upgrade path for the processor itself. The chip supports dual-channel memory with DDR4 and LPDDR4X modules, though the exact speeds are not specified in the database. It does not support ECC memory, which is expected for a consumer mobile part. For expansion, the CPU provides 4 PCIe Gen 4 lanes, which are CPU-only — this is a limited number, but it is sufficient for a single NVMe SSD or a low-power discrete GPU. The integrated graphics controller can drive external displays, but the exact number of display outputs is not listed. The platform is end-of-life, so motherboard and driver support may be limited going forward. The 10 nm process node and 144 mm² die size are part of the chip’s physical characteristics, but they do not affect compatibility directly.

Power and Thermals

The TDP of 15 watts is the defining thermal characteristic of the i5-1135G7. This low power envelope allows for fanless or near-silent cooling in ultraportable designs, but it also imposes strict limits on sustained performance. The base clock of 1.50 GHz is relatively low, which helps keep power consumption down during idle or light loads. The boost clock of 4.20 GHz, however, is only achievable for short bursts when the thermal headroom is available. In practice, the CPU will likely drop to lower frequencies under sustained multi-threaded loads to stay within the 15 W limit. The integrated Iris Xe Graphics also shares the same thermal budget, so gaming or GPU-intensive tasks will further reduce CPU boost clocks. A capable cooling solution — even a small heatpipe and fan — can help maintain higher boost frequencies, but the absolute power limit is the primary constraint. For users who prioritize battery life and low heat, this is an ideal design; for those who need heavy, sustained computation, the 15 W TDP will be a bottleneck. The 50th percentile performance is achieved within this power budget, which is a testament to the efficiency of the Tiger Lake architecture.
