Core i7-8705G Details

Ranked #520 of 2060 in overall performance, the Intel Core i7-8705G remains a capable mobile processor despite its age, having been launched in January 2018. While it is now over eight years old, its hybrid architecture—combining Intel's Kaby Lake-G core design with AMD’s Radeon RX Vega M GL graphics—positions it as a unique offering in the mobile segment. At the time of its release, the i7-8705G stood out for its integrated GPU performance, which was significantly stronger than standard Intel HD Graphics solutions, making it a notable choice for thin-and-light laptops requiring both CPU and graphics power. As of March 2026, it sits well behind modern processors in the market, but still holds relevance for users with legacy systems or those prioritizing graphics performance in a compact form factor.

The processor features four cores and eight threads thanks to Intel Hyper-Threading, operating at a base frequency of 3.1 GHz and boosting up to 4.1 GHz under load. It is built on a 14 nm process and uses the BGA2270 package, making it suitable for integration into laptops rather than desktops. With a 65 W TDP, the i7-8705G maintains a balanced power profile, ideal for mobile systems where thermal constraints are critical. It supports dual-channel DDR4-2400 and DDR3L-1600 memory, with a maximum capacity of 64 GB, and features a 35.76 GiB/s memory bandwidth. The chip includes 8 MiB of L3 cache, 1 MiB of L2 cache, and 0.25 MiB of L1 cache, ensuring efficient data handling across its cores.

One of the i7-8705G’s most distinctive features is its integrated GPU, which combines Intel HD Graphics 630 with AMD’s Radeon RX Vega M GL. This hybrid design enables a burst frequency of up to 1.1 GHz and includes 24 execution units, allowing it to handle moderate gaming and multimedia tasks more effectively than standard integrated graphics. The GPU supports up to three displays and can access up to 64 GB of system memory. This combination gives the i7-8705G a unique edge in mobile workstations where discrete GPUs are not feasible.

In terms of performance, the i7-8705G achieves a Passmark Overall Score of 5,443, placing it at #520 in the global ranking. Its single-core score of 5,703 ranks it #414, indicating strong performance in tasks that rely on individual core speed. However, its multicore score of 5,054, ranking #601, shows a more modest performance in multi-threaded workloads, especially when compared to modern multi-core processors. While it outperforms some older desktop CPUs like the Core i5-8400, it falls behind newer mobile processors such as the Core i7-1185G7 and Ryzen 3 4100 in both single- and multi-core performance.

The i7-8705G supports a range of advanced technologies, including Intel’s Turbo Boost 2.0, Hyper-Threading, AVX, AVX2, AES-NI, and Intel VT-x and VT-d virtualization. It also includes security features like Intel Secure Key and Intel Identity Protection Technology. Despite its age, it remains compatible with modern software stacks and can run most applications efficiently. However, its lack of support for newer instruction sets like AVX-512 limits its suitability for cutting-edge computational tasks.

In conclusion, the Core i7-8705G is a legacy mobile processor that excels in integrated graphics performance for its time, particularly in hybrid platforms. While it no longer competes with current-generation CPUs in raw performance, it remains a viable option for users who value graphics capability in a compact mobile design. For modern workloads, especially those requiring high single-core performance or extensive multi-threading, newer processors offer significantly better value. However, for legacy systems or niche use cases, the i7-8705G still delivers a balanced mix of CPU and GPU performance.
