Key Features at a Glance
1. Core Performance: Coffee Lake Efficiency
Reliable for budget gaming and productivity in 2025.
4-Core Coffee Lake (4 Threads):
Built on 14nm process, the quad-core design handles everyday computing and light multitasking effectively. It provides 10-15% higher performance than the i3-8100 in benchmarks like Cinebench R23, scoring around 4,500 in multi-core tests. Suitable for office tasks and entry-level gaming when paired with a capable GPU.[web:400][web:407]
3.6 GHz Base / 4.2 GHz Boost:
Turbo Boost 2.0 delivers up to 4.2 GHz for single-threaded tasks, achieving Geekbench 6 single-core scores around 1,100. The base frequency ensures stable performance in sustained loads like web browsing and video playback. In 2025 gaming tests with an RTX 2060, it maintains playable frame rates in titles like Fortnite at 1080p.[web:407][web:403]
6MB Smart Cache:
Intel Smart Cache enhances data retrieval for multitasking, contributing to overall efficiency in budget setups. It supports up to 37.5 GB/s memory bandwidth with DDR4-2400, aiding in simple productivity apps. However, the lack of Hyper-Threading limits it in heavily multi-threaded scenarios compared to modern CPUs.[web:397][web:413]
2. Graphics & Expansion: Discrete Focus
Tailored for dedicated GPU builds.
No Integrated Graphics:
Discrete GPU Required for display and gaming, making it ideal for budget builds with add-in cards like GTX 1650. This “F” variant saves cost over models with UHD 630 iGPU, focusing resources on CPU performance. In 2025 tests, it pairs well with mid-range GPUs for 1080p esports titles.[web:397][web:403]
LGA 1151 / 300-Series:
Chipset Compatibility with B360/H370/Z390 boards supports DDR4 platforms up to 64GB. PCIe 3.0 x16 slot enables GPU expansion, though it limits newer PCIe 4.0 devices. This setup remains viable for cost-effective upgrades in 2025.[web:397][web:413]
DDR4-2400 Support:
Dual-Channel Memory up to 64GB with 37.5 GB/s bandwidth suits basic workloads. ECC support adds reliability for light server use, though max speed of 2400 MHz is modest by 2025 standards. It performs adequately in gaming with fast RAM kits.[web:397][web:413]
3. Build Integration & Efficiency
Easy integration for budget PCs.
65W TDP:
Low Power Draw requires only standard air cooling, keeping system temps under 70°C in loads. This efficiency suits small form factor builds and reduces electricity costs for daily use. No overclocking support keeps it simple for beginners.[web:397][web:413]
Compact Design:
LGA 1151 Package measures 37.5 x 37.5 mm for easy installation in mid-tower cases. 8 GT/s bus speed ensures quick communication with peripherals via motherboard. Supports Windows 10/11 for broad OS compatibility.[web:397]
USB 3.1 Support:
Via Motherboard provides up to 10 Gbps ports for peripherals, enhancing connectivity in budget rigs. PCIe 3.0 lanes support NVMe SSDs, though speeds cap at Gen3 limits. Overall, it offers solid value for non-demanding 2025 setups.[web:397][web:413]
