Conclusion 
Average Bench 71.4%
Average Bench 51.6%

The Core i7-4790 is the third upgrade to Intel's flagship quad core hyper-threaded CPU. This version, like its predecessor the i7-4771, gets a 100 MHz bump in stock frequency and additionally the i7-4790 also gets a 100 MHz turbo frequency bump. These improvements (~4%) are marginal and practically impossible to discern in day to day use. Looking at a benchmark comparison between the 4771 and 4790 verifies that there is little difference between the two CPUs. Although the i7-4790 isn't much of a step forward, it's still one of the best (locked) mainstream processors on the market. AMD hasn't been able to compete with Intel on single threaded performance for several years, consequently Intel have no need to push the envelope. Overclockers should wait for the 4790K which is rumoured to be released shortly. [May '14 CPUPro]

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 the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
