Intel Core i7-1250U

The Intel Core i7-1250U is a 10-core, 12-thread mobile processor built on Intel's Alder Lake architecture, fabricated on a 10 nm process. It operates with a base clock of 1100 MHz and a boost clock of 4.70 GHz, within a 9 TDP envelope. The chip is socketed in Intel BGA 1781 and integrates Iris Xe graphics with 96 execution units. Benchmark results place it at the 72nd percentile of all CPUs, with an average benchmark score of 13462.

Platform and Compatibility

The i7-1250U is a mobile-only processor using the Intel BGA 1781 socket, which is a soldered, non-upgradeable package. The production status is active, indicating ongoing availability in thin-and-light laptops and ultrabooks. The platform supports dual-channel DDR4 and DDR5 memory, with no ECC capability. Memory bus width is dual-channel, but the fact pack does not specify a maximum bandwidth. PCIe connectivity is Gen 4, which provides modern I/O throughput for NVMe storage and discrete GPUs, though the integrated graphics (Iris Xe 96EU) may be the primary display output in most designs.

The architecture is Alder Lake-U, part of the Core i7 generation. The 10 nm process node and Intel as the foundry are confirmed. The cache hierarchy consists of 80 KB L1 per core, 1.25 MB L2 per core, and 12 MB shared L3. The processor is not multiplier-unlocked, so overclocking is not supported. The market segment is explicitly mobile, and the release date is February 22, 2022. No launch MSRP is provided, so no pricing information is available.

Upgrade path is limited by the BGA socket; the processor is not user-replaceable. The platform is designed for a specific chassis and cannot be transferred to a different motherboard. The dual-channel memory controller and PCIe Gen 4 support are the key connectivity features, but the lack of ECC and locked multiplier align with its mainstream mobile positioning.

Who Should Consider It

Benchmark data suggests the i7-1250U is suited for productivity and general-purpose workloads rather than heavy multi-threaded rendering. In Cinebench R23, it scores 9629 in multicore and 1359 in singlecore. The multicore figure is competitive for a 9-watt part, but the singlecore score of 1359 indicates strong per-thread performance for everyday applications. Geekbench results show 5777 multicore and 1661 singlecore, reinforcing that the chip handles office suites, web browsing, and light content creation with ease.

For office tasks, the Passmark single-thread score of 2703 and integer math score of 40328 indicate responsive interaction in spreadsheet, word processing, and email applications. The floating-point math score of 26625 suggests adequate capability for photo editing and light 3D modeling. Data compression and encryption scores—119280 and 7642 respectively—point to solid performance in file archiving and VPN/encryption workloads. The extended instructions score of 6497 and prime number finding score of 58 are less impressive, but these are niche workloads.

The integrated Iris Xe 96EU graphics provide enough GPU power for video playback and casual gaming, though the fact pack does not include gaming-specific benchmarks. The 10-core/12-thread configuration, while not a true 12-core part, offers good parallel throughput for compiling, batch image processing, and multitasking. However, the 9 TDP limits sustained all-core boost, so long-running multi-threaded tasks will see throttling compared to higher-TDP parts.

This processor is not ideal for demanding video editing or 3D rendering, as the Cinebench R20 multicore score of 4044 and R15 multicore score of 970 are modest. The Passmark multithread score of 11329 and physics score of 881 further indicate that heavy compute workloads will be slow. Instead, the i7-1250U is best suited for ultraportable laptops where battery life and thermal efficiency are prioritized over raw performance.

How It Compares

The i7-1250U sits within a tight cluster of average benchmark scores. Against the Intel Core i3-10105, the i7-1250U is 0.2% faster in average score (13462 vs 13430). This delta is negligible, meaning the two chips perform nearly identically in aggregate, despite the i3-10105 being a desktop part. The i7-1250U achieves this parity with a far lower TDP (9 vs the i3-10105's unspecified TDP), which is notable for mobile efficiency.

Compared to the Intel Core i3-12100F, the i7-1250U is 0.4% slower (13462 vs 13516). The i3-12100F is a desktop chip with a higher power envelope, so the small deficit is expected. In single-threaded workloads, the i7-1250U's boost clock of 4.70 GHz helps it remain competitive, but the i3-12100F's architecture (also Alder Lake) gives it a slight edge in average score.

The AMD Ryzen Threadripper PRO 3975WX is a high-end desktop workstation processor, yet the i7-1250U trails it by only 0.5% in average benchmark score (13462 vs 13534). This is surprising given the Threadripper's massive core count and power draw. The explanation lies in the average score metric, which may weight single-threaded performance heavily; the i7-1250U's strong single-core boost compensates for its lower multi-core throughput.

Finally, the i7-1250U is 1.4% faster than the Intel Core i7-7700K (13462 vs 13280). The 7700K is a 2017 desktop flagship with 4 cores and 8 threads, so the i7-1250U's 10-core/12-thread design and newer architecture deliver a clear, albeit modest, advantage in average score. This comparison highlights how far mobile processors have come, as a low-power U-series chip now outperforms a previous-generation desktop K-series part.

Benchmark Performance

The i7-1250U delivers a balanced profile across synthetic benchmarks. In Cinebench R23, the multicore score of 9629 and singlecore score of 1359 show a ratio of roughly 7:1, which is typical for a hybrid architecture with 10 cores. The R20 scores (4044 multicore, 570 singlecore) and R15 scores (970 multicore, 136 singlecore) follow similar trends. These figures indicate that the processor excels at bursty single-threaded tasks, such as application launches and web rendering, while providing respectable multi-threaded throughput for its power class.

Geekbench results reinforce this: a multicore score of 5777 and singlecore score of 1661. The singlecore number is particularly strong, likely due to the 4.70 GHz boost clock on the performance cores. In Passmark, the multithread score of 11329 and single-thread score of 2703 confirm that the i7-1250U handles concurrent workloads better than most low-power parts. The integer math score of 40328 and floating-point math of 26625 show solid arithmetic capability, while data compression (119280) and encryption (7642) scores indicate good throughput for file and network tasks.

The processor's average benchmark score of 13462 places it at the 72nd percentile of all CPUs. This percentile is a global ranking, meaning the i7-1250U outperforms 72% of all processors in the database, despite being a mobile chip. The nearest rivals—i3-10105, i3-12100F, Threadripper PRO 3975WX, and i7-7700K—all have average scores within a 1.4% range, illustrating that the i7-1250U occupies a competitive middle ground.

Specifically, the i7-1250U is 0.2% faster than the i3-10105, 0.4% slower than the i3-12100F, 0.5% slower than the Threadripper PRO 3975WX, and 1.4% faster than the i7-7700K. These deltas are small, but they show that the i7-1250U can match desktop processors from previous generations and even some current entry-level desktop chips, all within a 9-watt power envelope. The single-threaded performance is the standout feature; the Cinebench R23 singlecore score of 1359 is within a few percent of many desktop parts, while the multicore score benefits from the 10-core configuration.

For real-world workloads, the Passmark data compression and encryption scores suggest that the i7-1250U handles ZIP archives and VPN traffic efficiently. The random string sorting score of 13593 and extended instructions score of 6497 are more moderate, but they do not represent typical user tasks. The physics score of 881 is low, indicating that gaming physics simulations will be limited, but the integrated Iris Xe 96EU is not intended for high-end gaming. Overall, the benchmark data shows a processor that is well-balanced for everyday mobile computing, with a clear emphasis on single-threaded responsiveness and energy efficiency.
