The AMD FX-4300 is a budget quad-core processor which unlike its predecessor, the Bulldozer FX-4100, is based on the Piledriver micro-architecture which was released in Q4 of 2012. Its base clock speed of 3.8 GHz boosts to 4.0 GHz in turbo mode and with appropriate cooling can be overclocked to speeds of over 4.5 GHz. Even though these numbers are impressive, the real world effective speed is only 66. This is ok for general computing and even gaming when coupled with an appropriate GPU. The user experience will, however, be noticeably snappier with a CPU that has better single-core performance. Whilst the FX-4300 is cheap, it’s not so differently priced from the hexa core FX-6300 which offers significantly improved multi-core performance. [Nov '14 CPUPro]

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
