Core i5-8305G Details

Ranking #664 of 2060 in overall performance, the Intel Core i5-8305G remains a noteworthy mobile processor despite its age, having been released in February 2018. Its benchmark scores reveal a processor that, while outdated by modern standards, still holds its own in the mid-tier segment for certain applications. The overall score of 5245 is complemented by a single-core score of 5437 and a multicore score of 4957, indicating a balanced but not exceptional performance profile. This places it just ahead of similarly aged Intel and AMD mobile chips like the Core i5-4670S and Xeon E5-2640 v4, while falling behind more recent quad-core designs such as the Core i5-10300H and Ryzen 3 7330U.

Built on Intel’s Kaby Lake microarchitecture and fabricated on a 14 nm process, the i5-8305G features four cores and eight threads thanks to Hyper-Threading, a key design choice that enhances its multitasking capabilities. Clock speeds range from a base frequency of 2.8 GHz up to a turbo boost of 3.8 GHz on a single core, with 3.6 GHz on two cores and 3.4 GHz on four cores. This dynamic scaling allows it to handle light workloads efficiently while maintaining performance under sustained load. The processor includes 6 MiB of L3 cache and 1 MiB of L2 cache, with 0.125 MiB of L1 cache per core, ensuring fast data access for typical computing tasks.

One of the standout features of the i5-8305G is its integrated graphics solution, combining Intel’s HD Graphics 630 with AMD’s Radeon RX Vega M GL. This hybrid approach delivers significantly higher graphics performance than standard integrated solutions, with a base GPU frequency of 350 MHz and a burst frequency of 1100 MHz. The GPU supports up to three displays and features 24 execution units, making it suitable for light gaming and multimedia applications. This combination of integrated graphics and processing power makes the i5-8305G a compelling choice for thin and light laptops that prioritize portability without sacrificing visual performance.

The processor operates within a 65 W TDP and uses a BGA2270 socket, which is typical for mobile devices where space and power efficiency are critical. It supports DDR3L-1600, DDR4-2400, and HBM2 memory types, with a maximum memory capacity of 64 GiB and a memory bandwidth of 35.76 GiB/s. This flexibility in memory support allows for future-proofing in certain systems, though real-world performance is constrained by the 14 nm process and lack of modern instruction set extensions. The i5-8305G also supports a range of Intel technologies, including AVX, AVX2, AES-NI, and Intel VT-x, enhancing its capabilities in encryption, virtualization, and scientific computing.

As of March 2026, the Core i5-8305G is best suited for users who require a capable mobile processor for general productivity, light content creation, and entry-level gaming. While it no longer competes with the latest CPUs in single-core or multicore performance, its integrated graphics and power efficiency continue to make it a viable option in budget-friendly laptops. However, for users seeking top-tier performance or future scalability, newer processors with advanced architectures and higher core counts are significantly more compelling.
