Intel Core i7-7820HQ

The Intel Core i7-7820HQ is a 45-watt mobile processor from the Kaby Lake-H generation, built on Intel's 14 nm process. Benchmark data places this chip at the 45th percentile among all CPUs, indicating it sits in the middle of the performance distribution. Its average benchmark score of 1922 places it in a tightly contested cluster, with its nearest rivals all scoring within a narrow 0.6% band. This is a processor that delivers solid, predictable quad-core performance, but it is firmly a product of its 2017 era, as reflected in its end-of-life production status and its performance standing relative to newer mobile parts.

Benchmark Performance

The Core i7-7820HQ's performance profile is defined by its 4 cores and 8 threads, which produce a consistent set of scores across multiple rendering and general-purpose benchmarks. In Cinebench R23, the processor achieves a multi-core score of 6098 and a single-core score of 861. The ratio between these scores, roughly 7:1, highlights the scaling capability of its eight threads, but the absolute single-core figure shows its architectural age compared to more recent designs. In Cinebench R20, it scores 2561 multi-core and 361 single-core, while in the older R15 test, it delivers 614 multi-core and 86 single-core. Geekbench results show a multi-core score of 3603 and a single-core score of 1188.

When positioned against its nearest rivals, the 7820HQ is statistically tied with the Intel Xeon E3-1575M v5, which has an identical average score of 1922, representing a 0% delta. The data shows a near-perfect equivalence between these two parts, making them interchangeable in raw compute terms. Against the Intel Core i5-1035G4, the 7820HQ is a mere 0.3% ahead, a margin well within run-to-run variance. This is notable because the i5-1035G4 is a newer, lower-power Ice Lake part, yet the older 7820HQ holds its own in multi-threaded workloads. The AMD Opteron 6348, a server-class chip, scores 1930, putting the 7820HQ 0.4% behind it, while the Intel Xeon E5-2620 v3 trails by 0.6% with a score of 1910. These deltas are negligible, meaning the 7820HQ delivers performance essentially identical to a spread of rival parts from different market segments and generations.

The practical interpretation is that the 7820HQ's performance is homogeneous with its direct contemporaries. It is not a leader, but it is also not an outlier on the low end. The 45th percentile ranking confirms this middle-of-the-road placement, suggesting that in a mixed workload environment, users will see adequate but unremarkable throughput.

Who Should Consider It

Given its 4-core/8-thread configuration and 45W TDP, the 7820HQ is best suited for users whose primary tasks are multi-threaded but not extreme. The Cinebench R23 multi-core score of 6098 indicates that it can handle moderate video editing, 3D rendering, and code compilation tasks with reasonable efficiency. Users engaged in these creation workloads will find the eight threads beneficial, as the multi-core scores are consistently within 0.6% of its closest rivals, meaning it will not bottleneck productivity relative to those alternatives. For office productivity—spreadsheets, document editing, web browsing—the single-core score of 861 in Cinebench R23 is more than adequate, as these tasks rarely scale beyond two threads.

Gaming is a more nuanced recommendation. The 7820HQ's single-thread performance is modest by modern standards, which may limit frame rates in CPU-bound titles, but the 4-core/8-thread layout provides enough headroom for contemporary games that utilize multiple cores. The integrated Intel HD Graphics 630 is not suitable for serious gaming, so a discrete GPU would be mandatory for any gaming use case. However, as a mobile processor, the 7820HQ would be found in laptops with dedicated graphics, making it a viable, if aging, option for 1080p gaming at medium settings. It is not recommended for users seeking high-refresh-rate esports performance, as the single-core scores fall short of newer parts.

Power and Thermals

The 7820HQ carries a TDP of 45W, which is the standard power envelope for performance-oriented mobile processors in its generation. This TDP class implies that a capable cooling solution is required—typically a dual-fan or larger heatpipe design found in thicker gaming or workstation laptops. The 14 nm process node from Intel means that thermal density is manageable, but sustained multi-core loads will generate significant heat. Users should expect that under full load, the processor will reach its thermal limits, potentially reducing boost clocks on the 3.90 GHz maximum. The base clock of 2.90 GHz provides a stable floor for all-core workloads, but the boost behavior will depend heavily on the laptop's cooling capacity. For users planning to run extended render or compile sessions, a laptop with a robust thermal solution is non-negotiable to maintain performance near the 6098 Cinebench R23 multi-core score.

How It Compares

Against the Intel Xeon E3-1575M v5, the 7820HQ is a perfect match, with both parts scoring exactly 1922 on average. The Xeon is a server-oriented mobile chip, and the data shows they are functionally identical in compute performance, making the choice between them dependent on platform features rather than speed.

The Intel Core i5-1035G4 is a newer, more efficient part, yet the 7820HQ edges it out by 0.3% in average score (1922 vs 1917). This suggests that the older 7820HQ retains competitive multi-threaded muscle, but the i5 likely offers better single-core efficiency and integrated graphics performance, which the data here does not capture.

The AMD Opteron 6348 is a server processor with a higher average score of 1930, placing the 7820HQ 0.4% behind. This is a negligible gap, showing that the mobile 7820HQ can keep pace with older server silicon in general benchmark workloads, though the Opteron likely has far higher core counts for specific server tasks.

The Intel Xeon E5-2620 v3 scores 1910, putting the 7820HQ 0.6% ahead. This is another server-class rival where the mobile chip holds a slight edge in average score. The delta is small enough that real-world differences would be imperceptible, but the 7820HQ's performance is validated as being within the same tier as these enterprise parts.

Single-Thread vs Multi-Thread Behavior

The 7820HQ exhibits a clear performance split between single-thread and multi-thread workloads. Its Cinebench R23 multi-core score of 6098 is approximately 7.1 times its single-core score of 861, which is a strong scaling ratio for a 4-core/8-thread part. This indicates that the processor efficiently utilizes its Hyper-Threading capabilities, making it well-suited for parallel tasks like rendering or video encoding. In contrast, the single-core scores—861 in R23, 361 in R20, and 1188 in Geekbench—are modest, reflecting the Kaby Lake architecture's limitations in raw IPC (instructions per clock). For everyday applications like web browsing, document editing, or light programming, the single-thread performance is sufficient, but it will lag behind newer processors in tasks that rely on a single fast core, such as legacy software or certain game engines. The multi-thread advantage is the 7820HQ's primary strength, making it a better choice for users who can leverage all eight threads rather than those needing maximum single-thread responsiveness.

Platform and Compatibility

The 7820HQ is built for the Intel BGA 1440 socket, which is a ball-grid array package soldered directly to the motherboard. This means the processor is not user-replaceable or upgradeable; the entire laptop or motherboard must be replaced for a CPU upgrade. The platform supports dual-channel DDR3 or DDR4 memory, offering flexibility but no ECC support. For expansion, the processor provides 16 PCIe Gen 3 lanes from the CPU, which is sufficient for a single high-end discrete GPU and one NVMe SSD, though bandwidth may be constrained if multiple devices compete for lanes. The integrated graphics is Intel HD Graphics 630, which supports standard display outputs but lacks the performance for demanding graphics tasks. The architecture is Kaby Lake, specifically the Kaby Lake-H variant, and the process node is 14 nm from Intel. Production status is end-of-life, meaning no new devices are being manufactured with this chip. The launch MSRP was $378, and it was released in early 2017. The lack of an unlocked multiplier confirms that this is a fixed-function mobile processor, with no overclocking headroom. Upgrade path is effectively non-existent due to the BGA socket, so users should consider the entire system's longevity rather than just the CPU.
