Intel Core i5-1145G7E

The Intel Core i5-1145G7E is a mobile processor from Intel’s Tiger Lake-U family, built for thin-and-light laptops. It packs 4 cores and 8 threads, a base clock of 1500 MHz, and a boost clock of 4.10 GHz, with a 28W TDP. Its average benchmark score across the database is 2131, placing it at the 48th percentile of all CPUs—a solidly mid-range result. The chip integrates Iris Xe Graphics G7 with 80 execution units, and it was released in September 2020 with a launch MSRP of $312. Below, we break down what the benchmark data actually means for real-world use.

Benchmark Performance

The i5-1145G7E’s benchmark results are consistent across Cinebench versions. In Cinebench R23, it scores 7371 points in multi-core and 1040 in single-core. In R20, the multi-core result is 3095 and single-core is 436. In R15, it reaches 742 multi-core and 104 single-core. These numbers show a typical scaling pattern for a 4-core/8-thread part: the multi-core scores are roughly seven times the single-core scores, though the exact ratio is not needed to see that the chip scales well with thread count.

The processor sits in a very tight cluster of rivals. Its average score of 2131 is 0.1% above the Intel Xeon E5-2630L v3 (2129) and the Intel Xeon E-2224G (2128), and 0.2% above the AMD Ryzen 5 7520C (2127). It is 0.5% behind the AMD Ryzen 5 2400G (2143). These deltas are negligible—within a fraction of a percent—so the i5-1145G7E effectively trades blows with all four rivals in aggregate performance. The 48th percentile confirms that it sits squarely in the middle of the CPU performance distribution, not a standout but far from a weakling.

Power and Thermals

With a TDP of 28W, the i5-1145G7E belongs to the low-power mobile segment. This is a common class for ultraportable and thin-and-light laptops, where thermal headroom is limited. A 28W TDP implies that a modest cooling solution—typically a small fan or a heatpipe with a low-profile cooler—is sufficient to keep the chip within its operating envelope. The 10nm process node (Intel’s Tiger Lake architecture) contributes to efficiency, but the exact power draw under load is not in the data. In practice, this TDP class allows for passive cooling in some designs, but most laptops will use an active fan. The chip is not designed for high-performance desktops; it is a mobile part that prioritizes battery life and portability over raw sustained throughput.

Single-Thread vs Multi-Thread Behavior

The single-core scores—1040 in R23, 436 in R20, and 104 in R15—are respectable for a 4-core mobile chip. The boost clock of 4.10 GHz is high for a low-power part, which helps single-threaded responsiveness. The multi-core scores (7371, 3095, 742) reflect the 8 threads available via Hyper-Threading. In real workloads, this split means the chip handles everyday tasks—web browsing, office applications, light photo editing—smoothly, because these are often single-threaded or lightly threaded. For heavier multi-threaded tasks like video encoding or 3D rendering, the 4-core/8-thread configuration provides a moderate boost, but it will not match higher-core-count parts. The data shows that the chip is balanced: it does not sacrifice single-thread performance for multi-thread, and vice versa. This is a typical trade-off for a 28W mobile part, where both responsiveness and battery life matter.

How It Compares

Intel Xeon E5-2630L v3 — The i5-1145G7E is 0.1% ahead of this older server chip in average score. The Xeon is a 10-core part from a different era, but the i5’s newer architecture and higher clocks allow it to match the Xeon’s aggregate performance. In practice, the i5 will feel snappier in single-threaded tasks, while the Xeon might have an edge in heavily multi-threaded server workloads, but the benchmark delta is negligible.

Intel Xeon E-2224G — The i5-1145G7E is 0.1% ahead of this Xeon E-2224G. The E-2224G is a desktop-class 4-core chip, but the i5’s higher boost clock and integrated graphics make it a more versatile mobile option. The benchmark tie suggests that the i5 can hold its own against a desktop part in short bursts, though sustained load may differ.

AMD Ryzen 5 7520C — The i5-1145G7E is 0.2% ahead of the Ryzen 5 7520C. This Ryzen is a Chromebook-oriented chip, so the i5’s slight lead in aggregate score indicates it is at least as capable for general productivity. The i5’s integrated Iris Xe graphics likely offer better GPU performance, though that is not reflected in these CPU-only benchmarks.

AMD Ryzen 5 2400G — The i5-1145G7E is 0.5% behind the Ryzen 5 2400G. The 2400G is a desktop APU with a higher TDP and more headroom, so a small lead is expected. However, the i5’s mobile efficiency and lower power draw make it a better fit for laptops, and the performance gap is within noise for most tasks.

Platform and Compatibility

The i5-1145G7E uses the Intel BGA 1449 socket, which is a soldered, non-upgradeable package. This is typical for mobile processors, meaning the chip is permanently attached to the motherboard. The platform is Tiger Lake-U, built on Intel’s 10nm process. The die size is 144 mm², and the cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 8 MB of shared L3. Memory support is dual-channel DDR4 and LPDDR4X, with no ECC support. The CPU provides 4 PCIe Gen 4 lanes from the CPU itself, which is a limited but sufficient allocation for a laptop. The integrated graphics is Iris Xe Graphics G7 with 80 execution units, which can drive multiple displays and handle light gaming. The platform is not upgradeable—the BGA socket means the CPU is fixed, so the only upgrade path is to replace the entire laptop. For a mobile part, this is standard.

Who Should Consider It

The i5-1145G7E is a solid choice for users who need a balanced mobile processor for everyday productivity. Its single-thread performance is strong enough for office suites, web browsing, and light coding, and the 8 threads provide a modest boost for multitasking. The integrated Iris Xe graphics is capable of casual gaming and video playback, though it is not a gaming powerhouse. For content creation, the multi-core scores (7371 in R23) indicate it can handle occasional video editing or 3D rendering, but it will be slower than a 6-core or 8-core part. The 48th percentile means it is a mid-range CPU—not a budget chip, but not a high-end one either. If you are looking for a laptop that can handle a mix of light to moderate workloads without breaking a sweat, and you value portability over extreme performance, this chip fits. However, if your work is heavily multi-threaded (e.g., professional video editing, 3D animation), you would be better served by a higher-core-count processor. For typical users—students, office workers, and casual gamers—the i5-1145G7E delivers a competent, efficient experience.
