Intel Core i7-8709G

The Intel Core i7-8709G is a mobile processor that sits in the 45th percentile of all CPUs in the database, a position that signals a mid-range standing rather than a performance leader. Its average benchmark score of 1950 places it in a tight cluster of competitors, with the data showing a spread of less than one percent against its nearest rivals, indicating that the chip’s overall performance is highly consistent with its direct peers. The benchmark results reveal a processor that is competent for mainstream tasks but does not push the envelope in raw compute, making its position in the market defined more by balance than by outright speed.

Benchmark Performance

The aggregate benchmark data shows a processor that is effectively tied with its closest alternatives. The average score of 1950 is nearly indistinguishable from the AMD Ryzen 5 PRO 3400GE, which scores 1954, a delta of -0.2%. Similarly, the Intel Xeon E3-1585L v5 posts 1957, a -0.3% difference, while the Intel Core i7-9850HL trails slightly with 1941, a +0.5% margin in favor of the i7-8709G. The AMD Ryzen 3 4300U is also within striking distance at 1938, a +0.6% advantage for the Intel part. These deltas are negligible in real-world terms, meaning the i7-8709G does not dominate or lose to any of these rivals by a meaningful margin in overall average performance.

Looking at specific workload benchmarks, the multicore results paint a clearer picture of its capabilities. In Cinebench R23, the i7-8709G scores 6743 points in multicore, which is a solid figure for a 65W mobile part. The Cinebench R20 multicore score of 2832 and the Cinebench R15 multicore score of 679 corroborate this level of throughput. These numbers suggest that the processor can handle multi-threaded applications like video rendering or code compilation, but the percentile rank of 45 indicates that many other CPUs, particularly desktop parts, will outpace it. The data implies that the i7-8709G’s performance is adequate for occasional heavy workloads, but it is not designed for sustained professional-grade compute.

Power and Thermals

The thermal design power (TDP) is listed at 65 watts, a figure that classifies this chip as a mainstream mobile processor rather than an ultra-low-power or high-performance desktop part. This TDP level suggests that a capable cooling solution is necessary, likely a dedicated laptop cooler with heat pipes and a fan, rather than a passive or thin-and-light design. The 65W envelope allows for the 4-core, 8-thread configuration to maintain its base clock of 3.10 GHz and boost clock of 4.10 GHz without immediate thermal throttling, but the data does not specify sustained clock behavior under load. The architecture is Kaby Lake G, built on Intel’s 14 nm process, which is a mature node that generally offers predictable thermal characteristics, though not the efficiency of newer processes. The integrated graphics, Radeon RX Vega M GH, are a notable part of this package, and the 65W TDP must also cover this GPU component, meaning the CPU portion may have less thermal headroom than a discrete CPU with the same TDP. Benchmark results indicate that the chip’s performance is stable enough to match its rivals, but users should expect that a robust cooling system is a prerequisite for maintaining those scores.

Single-Thread vs Multi-Thread Behavior

The split between single-thread and multi-thread scores reveals a processor that is relatively stronger in multi-core tasks, though not dramatically so. In Cinebench R23, the single-core score is 952, while the multi-core score is 6743, resulting in a ratio of roughly 7.1 to 1, which is typical for a 4-core, 8-thread part. The Cinebench R20 results show a single-core score of 399 against a multi-core score of 2832, a ratio of about 7.1 to 1 as well. In Cinebench R15, the single-core score is 95, and the multi-core score is 679, again a similar ratio. This consistency indicates that the processor scales well with additional threads, meaning that the hyper-threading implementation is effective. For single-threaded workloads, the 952-point R23 score is moderate; it will handle everyday applications like web browsing, office documents, and light coding without issue, but it will lag behind higher-clocked desktop CPUs in tasks like legacy software or certain games that rely heavily on one core. The boost clock of 4.10 GHz helps single-thread performance, but the architecture’s age is a limiting factor. The data suggests that this chip is better suited for workloads that can utilize all 8 threads, such as batch photo editing or video transcoding, rather than tasks that depend on a single fast core.

Who Should Consider It

Given the benchmark data, the i7-8709G is a fit for users who need a balanced mobile platform with a strong integrated GPU, though the CPU scores themselves are not exceptional. For gaming, the integrated Radeon RX Vega M GH is a significant asset, but the CPU’s single-thread scores in Cinebench R23 (952) suggest that older or less optimized game engines may become CPU-bound. The multi-thread scores (6743 in R23) are sufficient for modern titles that use multiple cores, but the 45th percentile ranking implies that dedicated gaming laptops with discrete GPUs will offer better frame rates. For content creation, the multi-core performance is adequate for occasional video editing or 3D rendering in Cinebench, as the 2832 R20 score indicates it can complete these tasks, but it will take longer than higher-tier processors. Office productivity and general use are well within its capabilities; the single-thread score of 399 in R20 handles spreadsheets, email, and web apps smoothly. The data does not show any ECC memory support, so this is not a chip for mission-critical server or workstation tasks. In essence, this processor targets mobile users who value a compact system with decent compute and a powerful integrated GPU, rather than those seeking top-tier CPU performance.

Platform and Compatibility

The i7-8709G uses the Intel BGA 2270 socket, which is a soldered, non-upgradeable platform, meaning the CPU is permanently attached to the motherboard. This is a mobile-specific design, and the market segment is listed as Mobile, confirming that it is intended for laptops or all-in-one systems. Memory support is limited to DDR4, with no ECC capability, which aligns with its consumer-focused positioning. The PCIe configuration is not listed in the data, so the number of lanes and version cannot be stated, but the lack of such details suggests that expansion options are typical of a mobile part, likely limited to what the motherboard provides. The integrated graphics, Radeon RX Vega M GH, are a key part of the platform, eliminating the need for a discrete GPU in many cases. The production status is Active, and the release date is January 31, 2018, which places it in the Kaby Lake G generation. The upgrade path is effectively nonexistent, as the BGA socket does not allow for swapping the processor. This means that any future performance improvements would require replacing the entire system. The 14 nm process node and Kaby Lake architecture are older designs, and the data does not indicate support for newer standards like PCIe 4.0 or DDR5, so the platform is limited to the technologies available at its release time.

How It Compares

Against the AMD Ryzen 5 PRO 3400GE, the i7-8709G is virtually identical, with a -0.2% delta in average score. Both chips are 4-core parts with similar integrated graphics capabilities, and the data shows no meaningful performance difference, so the choice between them would come down to platform features rather than raw speed.

The Intel Xeon E3-1585L v5 is a slightly stronger performer, with an average score of 1957 versus 1950, a -0.3% delta. The Xeon part is also a 4-core, 8-thread processor, but it is an older architecture, and the i7-8709G’s newer Kaby Lake design does not close the gap, suggesting that the Xeon’s higher clocks or memory configuration give it a minor edge.

The Intel Core i7-9850HL trails the i7-8709G by 0.5%, with an average score of 1941 versus 1950. This is a small margin, but it shows that the i7-8709G has a slight advantage over this rival, likely due to a higher boost clock or better turbo behavior, though the difference is too small to notice in practice.

The AMD Ryzen 3 4300U is the closest competitor in this group, with a 0.6% deficit, scoring 1938 against 1950. The Ryzen 3 is a 4-core part without hyper-threading, yet its higher base clocks nearly compensate, meaning that the i7-8709G’s extra threads provide only a marginal benefit in this comparison.
