Intel Core i3-8300: Budget Processor for Basic Tasks in 2025
April 2025
Key Features: Coffee Lake Architecture and Modest Performance
The Intel Core i3-8300 processor, released in 2018, is based on the Coffee Lake microarchitecture with a 14 nm process technology. Despite its age, it still appears in budget builds and office PCs.
Key Specifications:
- 4 cores / 4 threads — the absence of Hyper-Threading limits multitasking capabilities.
- Base clock: 3.7 GHz — fixed, without Turbo Boost.
- L3 cache: 8 MB — adequate for simple applications.
- TDP: 62 W — low power consumption.
- Integrated graphics: Intel UHD Graphics 630 — supports 4K@60 Hz via HDMI/DisplayPort.
Performance (Geekbench 6):
- Single-Core: 1274 — acceptable for basic tasks.
- Multi-Core: 3710 — lags behind modern 4-core processors with SMT support (e.g., Ryzen 3 5300).
Features:
- Supports Intel Quick Sync Video — accelerates video encoding.
- Compatibility with Optane Memory (for models with H370/Z370 chipsets).
Compatible Motherboards: LGA 1151 v2 Socket and 300 Series Chipsets
The processor uses the LGA 1151 v2 socket but only works with 300 series chipsets:
- H310/B360/H370 — for office PCs (non-overclockable).
- Z370/Z390 — supports memory overclocking and upgrading to more powerful CPUs (e.g., i7-8700K).
Examples of motherboards in 2025:
- ASUS Prime B360M-A (about $70) — basic model with M.2 and USB 3.1.
- Gigabyte Z390 UD ($90–$110) — for upgrades and discrete graphics.
Tip: In 2025, new LGA 1151 v2 motherboards are rarely produced — seek out leftovers in warehouses or trusted used options.
Memory Support: Only DDR4
The i3-8300 operates with DDR4-2400/2666 MHz (frequency depends on the chipset):
- B360/H310 — up to 2666 MHz.
- Z370/Z390 — overclocking up to 3000+ MHz (with XMP).
Recommendations:
- Optimal capacity is 16 GB (2x8 GB). For example, Kingston Fury DDR4-2666 ($45).
- DDR5 and LPDDR4x are not supported — this is a primary limitation for upgrades.
Power Supply: Minimum 400W with Headroom
With a TDP of 62 W, the processor is not demanding on the PSU:
- Without discrete graphics: 300–350 W is sufficient (e.g., be quiet! Pure Power 11 350W, $50).
- With a graphics card like NVIDIA GTX 1650: 450–500 W (Corsair CX450, $55).
Important: In 2025, power supplies with an 80+ Bronze certification or higher are relevant. Avoid cheap noname models — they may provide unstable performance with modern graphics cards.
Pros and Cons of i3-8300 in 2025
Pros:
- Low price ($100–$120 for a new unit).
- Energy efficiency — suitable for compact builds.
- Integrated graphics for office tasks and media centers.
Cons:
- No Hyper-Threading — 4 threads are outperformed by modern 4C/8T CPUs.
- Outdated platform — no support for PCIe 4.0, DDR5.
- Limited upgrade path — maximum Coffee Lake (i9-9900K).
Usage Scenarios: What Can i3-8300 Handle?
1. Office Tasks:
- Working with documents, browser (20+ tabs), Zoom/Teams.
- Example: build based on i3-8300 + 8 GB DDR4 + SSD — $250.
2. Multimedia:
- Watching 4K videos, streaming (via Quick Sync).
- Mini-PC for TV (e.g., in an ASRock DeskMini case).
3. Light Gaming:
- On integrated graphics: CS:GO (60 FPS on low), Minecraft.
- With a graphics card (GTX 1650): GTA V (1080p/medium), Fortnite.
4. Servers:
- NAS or home server based on Proxmox/TrueNAS.
Comparison with Competitors: Ryzen 3 and Others
- AMD Ryzen 3 3300X (2020):
- 4C/8T, 3.8–4.3 GHz, Geekbench 6 Multi-Core ~4200.
- Price: $130 (new).
- Pros: Better multithreading, PCIe 4.0 support.
- Intel Core i3-12100 (2022):
- 4C/8T, 3.3–4.3 GHz, Geekbench 6 Multi-Core ~5500.
- Price: $140.
- Pros: Alder Lake architecture, DDR5.
Conclusion: i3-8300 falls short even against budget models from 2022–2023, but it has a competitive price in the used market.
Practical Building Tips
1. Motherboard: Choose B360/Z390 with HDMI and M.2 for SSDs.
2. Cooling: The stock cooler will suffice — for example, DeepCool GAMMAXX 400 ($20).
3. Storage: Make sure to include an SSD (Kingston A400 480 GB — $35).
4. Case: Mini-ITX for compactness (Fractal Design Node 304 — $80).
Example build for $400:
- CPU: i3-8300 ($110)
- Motherboard: ASRock B360M-HDV ($70)
- Memory: 16 GB DDR4-2666 ($45)
- SSD: 500 GB NVMe ($40)
- PSU: 450 W ($55)
- Case: Thermaltake Versa H15 ($50)
Final Conclusion: Who Is i3-8300 Suitable for in 2025?
This processor should be considered only in two cases:
1. Budget Build: If you need a PC for office work, study, or a media center for minimal money.
2. Upgrading an Old System: Replacing outdated Pentium/Celeron processors on LGA 1151 v2.
Alternative: For the same $200–300, it is possible to build a PC based on Ryzen 5 5500 (6C/12T) or Intel i3-13100 with DDR5, but this will require new components.
The i3-8300 is not the best choice in 2025, but it can still serve in niche scenarios where price is more important than performance.
