Core i5-8500B Details

Ranking #511 of 2060 in overall performance, the Intel Core i5-8500B delivers a compelling blend of efficiency and integrated graphics, particularly for mainstream desktop users. Despite its release over four years ago, the processor maintains relevance in budget and mid-tier builds due to its solid single-core performance and low power consumption. Built on Intel's Coffee Lake architecture at 14 nm, the i5-8500B is designed for the mobile market segment, though it's commonly used in compact desktops. Its 6-core, 6-thread design, paired with a base clock of 3.0 GHz and a turbo frequency of up to 4.1 GHz, makes it a capable performer in everyday productivity and light multitasking scenarios.

The processor features a 9 MiB L3 cache and 1.5 MiB of L2 cache, with a total L1 cache of 0.375 MiB, distributed as 0.188 MiB for both L1 data and instruction caches. It supports DDR4-2666 memory across two channels, with a maximum capacity of 64 GiB and a memory bandwidth of up to 39.74 GiB/s. With a TDP of 65 W and a 14 nm CMOS process, the i5-8500B emphasizes energy efficiency without sacrificing performance, making it suitable for low-power systems and compact form factors.

Integrated into the chip is Intel’s UHD Graphics 630, which offers 24 execution units and a base frequency of 350 MHz, boosting up to 1.1 GHz under load. This GPU supports up to three displays and is sufficient for office applications, HD video playback, and light gaming. The processor supports a wide array of instruction sets, including AVX2, AES-NI, and Intel VT-x, ensuring compatibility with modern software and virtualization tasks. It also supports Intel’s Turbo Boost 2.0 and Enhanced SpeedStep technologies, allowing dynamic frequency scaling based on workload and power conditions.

In benchmark testing, the i5-8500B achieves a single-core score of 5819, placing it at #347 of 2060—outperforming many high-end processors of its time, including the Core i7-5950HQ and Ryzen Threadripper 1900X. Its multicore score of 4926 ranks it #697 of 2060, slightly behind the Core i5-7600 and Xeon E5-2660 v2, but ahead of the Core i5-9400T and Core i5-8350U. This indicates that while the i5-8500B excels in single-threaded applications, its multicore performance is more modest, reflecting its design focus on efficiency over raw throughput.

As of March 2026, the Core i5-8500B remains a viable option for users seeking a reliable, low-power processor for general computing, office work, and light multimedia tasks. Its strong single-core performance and integrated graphics make it a good fit for compact desktops and small business environments where discrete GPUs are unnecessary. While it's no longer competitive with modern high-end CPUs, its performance and efficiency continue to justify its presence in the market.
