About Intel Core i3-8145U

The Intel Core i3-8145U is a 2-core, 4-thread mobile processor built on Intel's 10nm Whiskey Lake architecture. It operates at a base clock of 2.10 GHz and a boost clock of 3.90 GHz, with a 15W TDP. The chip integrates UHD Graphics 620 and supports DDR4 memory. Its launch MSRP was $281. This report evaluates its performance against nearest rivals using benchmark data.

Benchmark Performance

The Core i3-8145U delivers a Cinebench R23 multicore score of 3216 and a single-core score of 454. In R20, it scores 1350 multicore and 190 single-core. The R15 multicore result is 324. These numbers place the processor in the 31st percentile of all CPUs, meaning it outperforms roughly a third of the market. Its average benchmark score is 1107. Comparing to its nearest rivals, the Ryzen 3 2200U, Opteron 4280, and PRO A12-8870 all share the exact same average score of 1107, with a delta of 0%. The Opteron 3280 trails slightly at 1106, a 0.1% difference. This means the i3-8145U is statistically tied with these competitors in overall performance, though the specific workload characteristics may differ. The multicore scores suggest modest parallel capability, while the single-core score indicates adequate responsiveness for everyday tasks.

The R23 multicore score of 3216 is substantially higher than the single-core score of 454, reflecting the presence of four threads across two cores. However, the absolute multicore numbers are low compared to modern desktop processors, which is typical for a 15W mobile part. The R20 multicore score of 1350 further confirms that multi-threaded workloads will be limited. For a chip in the 31st percentile, users should expect it to handle light productivity without difficulty but to struggle with intensive rendering or compilation tasks. The single-core score of 454 in R23 is respectable for its class, indicating that single-threaded applications like web browsers, office suites, and basic scripting will feel snappy. Overall, the benchmark profile places this CPU at the entry level of the mobile performance spectrum.

Power and Thermals

With a TDP of 15W, the i3-8145U belongs to the ultra-low-power class typical of thin and light laptops. This low thermal design power allows for passive cooling in some chassis or a small fan, but the exact cooling solution is not specified. The 10nm process node contributes to efficiency, though the actual power draw is not directly measured here. The 15W envelope means that sustained performance may be limited by thermal throttling in constrained designs, but the boost clock of 3.90 GHz suggests short bursts of higher performance are possible. For a 2-core/4-thread part, the power budget is modest, making it suitable for fanless or near-silent operation in lightweight notebooks. The low TDP also implies that a capable air cooler—even a small one—can manage the heat output, but the exact cooling tier is not detailed in the data. This processor is clearly designed for scenarios where energy efficiency and low heat generation are priorities over raw performance.

Platform and Compatibility

The processor uses the Intel BGA 1528 socket, which is a soldered design, meaning it is not upgradeable without replacing the entire motherboard. This is a critical limitation for users who might want to swap processors later. It supports dual-channel DDR4 memory with a peak bandwidth of 38.4 GB/s. The memory bus is dual-channel, which is typical for this class. PCIe connectivity is Gen 3 with 16 lanes available from the CPU, allowing for dedicated GPUs or fast NVMe storage, though in practice most laptops will allocate lanes to the integrated UHD Graphics 620 and other peripherals. The chip does not support ECC memory. The production status is end-of-life, and the release date was September 30, 2018. The multiplier is locked, so overclocking is not possible. The integrated UHD Graphics 620 provides basic display output but is not intended for demanding 3D workloads. Given the BGA socket and end-of-life status, the upgrade path is essentially nonexistent; users must rely on the entire laptop being replaced for any performance improvement.

Who Should Consider It

The i3-8145U is best suited for users who need a basic laptop for office productivity, web browsing, and light multitasking. Its single-core performance of 454 in Cinebench R23 is sufficient for responsive everyday applications, while the multicore score of 3216 indicates that heavy multi-threaded tasks like video editing or 3D rendering will be slow. The integrated UHD Graphics 620 can handle casual gaming at low settings, but not demanding titles. Given its 15W TDP and mobile socket, it is intended for thin-and-light notebooks where battery life and low heat are priorities. Users who require more processing power for creation workloads should consider higher-tier processors, as the 31st percentile ranking places this chip below the majority of CPUs. For students, office workers, or travelers who primarily use word processors, spreadsheets, and web apps, the i3-8145U offers adequate performance in a power-efficient package. However, anyone planning to run virtual machines, compile large codebases, or edit high-resolution video will find the dual-core configuration limiting.

Single-Thread vs Multi-Thread Behavior

The benchmark results show a clear split between single-thread and multi-thread performance. In Cinebench R23, the single-core score is 454, while the multicore score is 3216. The R20 scores are 190 and 1350, respectively. The multicore scores are several times higher than the single-core scores, which is expected for a dual-core part with Hyper-Threading (4 threads). However, the absolute multicore numbers are low compared to modern desktop processors, reflecting the limited core count. The single-core performance is relatively stronger, which means tasks that rely on a single thread—such as many office applications, web browsing, and light coding—will feel more responsive than the multicore scores might suggest. Conversely, tasks that scale across all threads, like video encoding or batch processing, will not benefit from significant parallel speedup. This behavior makes the chip a better fit for interactive workloads than for background number-crunching. The single-core score of 454 is particularly notable because it indicates that the processor can handle daily tasks without noticeable lag, even if the multicore score of 3216 places it in the lower tier for parallel performance.

How It Compares

AMD Ryzen 3 2200U: The Ryzen 3 2200U matches the i3-8145U with an identical average benchmark score of 1107 and a delta of 0%. This indicates that the two processors deliver comparable overall performance in synthetic benchmarks, though their architectural differences may affect real-world tasks differently. The i3-8145U's higher boost clock of 3.90 GHz could give it an edge in single-threaded scenarios, but the data does not break down per-core scores for the rival.

AMD Opteron 4280: The Opteron 4280 also shares the same average score of 1107 with a 0% delta. Despite being a server-oriented part, its performance aligns closely with the i3-8145U, suggesting that the mobile chip can hold its own in certain workloads. The Opteron's higher core count is not reflected in the average score, implying that the i3-8145U's efficiency compensates for its lower core count.

AMD PRO A12-8870: The PRO A12-8870 again ties with the i3-8145U at 1107 average score and 0% delta. This reinforces the notion that the i3-8145U sits in a performance tier shared by several AMD processors. Users upgrading from a system with a PRO A12-8870 would see similar benchmark performance, though the i3-8145U's newer architecture and lower TDP may offer better battery life.

AMD Opteron 3280: The Opteron 3280 comes in at 1106, a 0.1% lower average score. While the difference is negligible, it places the i3-8145U slightly ahead in this comparison. The delta of 0.1% is within measurement noise, so the two are effectively equivalent in overall performance. This further confirms that the i3-8145U is a solid entry-level mobile processor that competes closely with a range of AMD parts.
