The AMD FX-4100 CPU
The AMD FX-4100 is a quad-core processor is basically a FX-8150 with 4-cores disabled. This obviously means that the chip has half of the L2 cache (4MB) enabled and a lower TDP (95W). The AMD FX-4100 even has the same 3.6 GHz base clock speed as the FX-8150, but differs slightly in Turbo mode as it is clocked lower. Turbo mode on the FX-4100 runs at just 3.7 (4 cores at load) or 3.8 GHz (2 cores at load), so it doesn't scale as high as the FX-8150.
The best part about the FX-4100 is without a doubt the price. The FX-4100 has a street price of $109.99 shipped, which is far less expensive than the FX-8150 that will set you back $269.99 shipped. Could the FX-4100 processor be the value play for the AMD desktop market? That is what we set to find out and we'll be comparing it against processors like the Intel Core i3-2120 quad-core 3.3GHz CPU that runs $127.01 shipped to see how this budget processors compare.
When running all the threads at 100% when using a application like handbrake the AMD FX-4100 was observed running at 3600MHz, which just happens to be the standard base clock speed for this processor.
AMD FX-4100 CPU Overclocking
Overclocking greatly varies due to what hardware is being used and who is doing the overclocking. Always remember that no two pieces of hardware will perform the same, so our results will differ from what you might be able to get.
Benchmark Results: The AMD FX-4100 didn't perform that bad in the game benchmarks, but it was just faster than the AMD A8-3850 and Intel Core i3-2120
Legit Bottom Line: The AMD FX-4100 didn't top the charts when it comes to CPU performance, but the low price and solid overclocking results make it a decent chip for those looking for a budget system build.
