Core i3-8300T Details

The Intel Core i3-8300T stands out for its exceptional single-core performance, ranking #551 of 2060 in single-core benchmarks with a score of 5505. This makes it a strong performer in tasks that rely heavily on individual core speed, such as gaming and general productivity workloads. Despite being a budget-oriented desktop processor, it holds its own against more powerful chips in this category, including the Core i5-6600 and even some higher-end Xeon models. The processor's standout performance in single-threaded applications is particularly notable given its 35 W TDP and energy-efficient design.

Launched in April 2018, the Core i3-8300T is built on Intel's Coffee Lake architecture and operates at a base frequency of 3.2 GHz, with no turbo boost capability. It features four cores and four threads, delivering a balanced performance profile for light multitasking and everyday computing. With a 14 nm manufacturing process, the chip integrates 8 MB of L3 cache and supports dual-channel DDR4-2400 memory, achieving a memory bandwidth of 38.4 GB/s. The processor is socketed in LGA-1151 and is compatible with 300-series chipsets.

Integrated graphics are provided by Intel's UHD Graphics 630, which features 23 execution units and can boost up to 1.1 GHz. While not suitable for modern gaming, it enables basic multimedia playback and light graphical tasks, making it a viable option for users who do not require a discrete GPU. The UHD Graphics 630 supports up to three displays and is capable of handling 4K video output at 30 Hz.

The Core i3-8300T supports a range of advanced technologies, including AVX, AVX2, AES-NI, and Intel's virtualization features such as VT-x and VT-d. It also includes ECC memory support, which is rare in consumer-grade CPUs and adds value for users running mission-critical applications. However, it lacks simultaneous multithreading, meaning it cannot leverage hyper-threading for improved multitasking efficiency.

In multicore performance, the processor scores 4916, placing it at #710 of 2060, which reflects its limitations in heavily threaded workloads. While it competes closely with mid-range processors like the Core i5-9500 and Ryzen 3 PRO 2200G, it trails behind more powerful chips in the same generation. Overall, the Core i3-8300T offers a compelling balance of efficiency and performance for basic desktop use, with strong single-core capabilities that make it a solid choice for budget builds and office environments.

As of March 2026, the Core i3-8300T remains relevant for users seeking a low-power, reliable CPU for non-intensive applications. Its low TDP and support for ECC memory make it a good fit for small form-factor PCs, digital signage, or embedded systems. While it no longer competes with modern high-end processors, it remains a capable option in the lower end of the desktop market, particularly for those prioritizing energy efficiency and integrated graphics.
