Intel Core i7-1185G7

The Intel Core i7-1185G7 is a 4-core, 8-thread mobile processor from the Tiger Lake-U family, built on Intel's 10 nm process. It operates at a 3.00 GHz base clock and reaches 4.80 GHz boost, within a 28 W TDP. With an average benchmark score of 12715, it sits at the 72nd percentile of all CPUs, placing it near the AMD EPYC 7502 (12709, 0% delta) and Intel Xeon Gold 6348 (12746, -0.2% delta) in overall performance. This analysis examines its platform, power, workload suitability, and competitive standing using the available benchmark data.

Platform and Compatibility

The i7-1185G7 uses the Intel BGA 1449 socket, a ball-grid array design that is typically soldered directly to the motherboard. This implies a non-upgradeable, integrated solution common in ultraportable laptops. The processor is part of the Tiger Lake architecture, specifically the Tiger Lake-U codename, and belongs to the Core i7 (Willow Cove-U) generation. It is fabricated on Intel's 10 nm process with a die size of 144 mm².

Memory support includes DDR4 and LPDDR4X, operating in a dual-channel configuration. The controller does not support ECC memory, so error-correcting memory is unavailable. For expansion, the CPU provides PCIe Gen 4 with 4 lanes from the CPU only, which limits the bandwidth available for discrete GPUs or high-speed storage to a single Gen 4 x4 link. The integrated graphics are Iris Xe-LP Graphics G7 with 96 execution units, providing a capable built-in display solution for mobile systems.

The market segment is explicitly mobile, and the production status is end-of-life, with a release date of September 2020. The part number is SRK1F, and the multiplier is locked, preventing overclocking. Given the BGA socket and mobile orientation, the upgrade path is effectively non-existent; users are tied to the original laptop design. The platform is thus best understood as a fixed, soldered component rather than a modular desktop CPU.

Power and Thermals

The TDP is rated at 28 W, which places the i7-1185G7 in the low-power mobile tier typical of thin-and-light laptops. This power envelope allows for compact cooling solutions, but sustained performance will depend heavily on the chassis' thermal design. The boost clock of 4.80 GHz is notably high for a 28 W part, suggesting that short bursts of single-thread performance can reach that frequency, while all-core workloads may settle to lower clocks under sustained load.

The 28 W TDP also implies that the processor is designed to operate within a modest thermal budget, making it suitable for passively cooled or fan-assisted designs in smaller form factors. However, the actual thermal behavior is not directly measured in the provided data; only the TDP class is specified. In practice, the combination of a high boost clock and low TDP indicates a trade-off between peak performance and sustained output, which is a common characteristic of ultrabook processors.

Who Should Consider It

The i7-1185G7's benchmark profile suggests it is a balanced performer for everyday tasks and moderate productivity. In Passmark, the single-thread score of 2778 is strong, indicating responsive application launches and smooth operation in single-threaded software. The multi-thread score of 10115, while lower than many desktop parts, is respectable for a 28 W mobile chip. Cinebench R23 scores of 1213 (single-core) and 8596 (multi-core) reinforce this: the single-core result is competitive, while the multi-core result reflects the 4-core/8-thread configuration.

For office workloads—word processing, spreadsheets, web browsing, and light multitasking—the high single-thread performance and a Passmark integer math score of 34211 ensure snappy interactions. The floating-point math score of 20126 also supports basic scientific or financial calculations. For content creation, the multi-core scores are adequate for occasional video encoding or 3D rendering, but not for heavy, continuous workloads. The Passmark data compression score of 104630 indicates good file archiving and compression throughput, while data encryption at 5598 suggests moderate security-related tasks. The extended instructions score of 7396 covers SIMD-heavy applications.

Gaming on the integrated Iris Xe-LP (96EU) is possible for older or less demanding titles, but no gaming benchmarks are provided. The CPU itself, with a single-thread score of 2778, would not bottleneck most casual games. However, the 4 PCIe Gen 4 lanes from the CPU limit the bandwidth for a discrete GPU, so users seeking high-end gaming would need a laptop with a separate GPU and appropriate PCIe allocation. The end-of-life status means this processor is no longer in production, so it is only relevant for existing systems or second-hand purchases.

How It Compares

The nearest rival list places the i7-1185G7 in close competition with several very different processors. Against the AMD EPYC 7502, the average benchmark scores are virtually identical: 12715 for the i7 versus 12709 for the EPYC, a delta of 0%. This is remarkable because the EPYC 7502 is a server-class CPU, but the overall average score—which includes a mix of single-thread and multi-thread tests—lands at the same level. The i7-1185G7 achieves this parity through superior single-thread performance, while the EPYC likely compensates with many more cores.

The Intel Xeon Gold 6348 scores 12746, which is 0.2% higher than the i7-1185G7. This difference is negligible, meaning the i7-1185G7 is statistically tied with a high-end server processor in the aggregate benchmark. The Xeon's advantage likely comes from its higher multi-thread throughput, but the i7's single-thread strength keeps the average close.

Compared to the Intel Core i3-12100, a desktop quad-core, the i7-1185G7 is 0.3% ahead (12682 vs 12715). The i3-12100 is a newer architecture, but the i7-1185G7's higher boost clock and integrated graphics may offset its older design. The delta is small enough that real-world differences are imperceptible.

Finally, the Intel Core i3-10105F, a budget desktop part, scores 12631, placing it 0.7% behind the i7-1185G7. Again, the difference is minimal. The i3-10105F lacks integrated graphics, while the i7-1185G7 includes Iris Xe-LP, making the i7 more versatile for mobile systems without a discrete GPU.

In all cases, the i7-1185G7's average score is within 1% of its nearest rivals, underscoring that this mobile 28 W part can compete with desktop and server chips in aggregate benchmarks, despite having only 4 cores.

Single-Thread vs Multi-Thread Behavior

The i7-1185G7 demonstrates a pronounced split between single-thread and multi-thread performance. In Cinebench R23, the single-core score is 1213, while the multi-core score is 8596, a ratio of roughly 7:1. This is expected for a 4-core/8-thread processor, but the absolute single-core number is high, indicating that the Willow Cove cores are efficient at boosting to 4.80 GHz under light loads. The Passmark single-thread score of 2778 is also strong, placing it in the upper tier for everyday responsiveness.

The multi-thread score of 10115 in Passmark is modest compared to the single-thread score, reflecting the limited core count. However, the scaling from single to multi is not linear; the 8 threads provide a 3.6x improvement over the single-thread score (10115 / 2778 ≈ 3.6), which is reasonable for a 4-core part with hyper-threading. This suggests that the processor can handle parallel tasks like video encoding or batch processing, but it will not match the throughput of higher-core-count CPUs.

For real workloads, this split means that the i7-1185G7 excels at tasks that rely on single-thread speed—such as opening applications, navigating spreadsheets, or running legacy software—while multi-threaded workloads like rendering or scientific simulations will see diminishing returns. The Passmark physics score of 763 and find prime numbers score of 47 are low, indicating that the CPU is not optimized for heavily parallel integer operations. Conversely, the floating-point math score of 20126 and integer math of 34211 show decent arithmetic throughput for typical office and light creation tasks.
