In terms of overall gaming performance, the AMD FX-6100 is massively better than the AMD Athlon 64 FX-74 Dual Core when it comes to running the latest games. This also means it will be less likely to bottleneck more powerful GPUs, allowing them to achieve more of their gaming performance potential.

The FX-6100 was released over three years more recently than the Athlon 64 FX-74, and so the FX-6100 is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Athlon 64 FX-74 when running the latest games.

The FX-6100 has 4 more cores than the Athlon 64 FX-74. With 6 cores, the FX-6100 is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

The FX-6100 has 4 more threads than the Athlon 64 FX-74. Both CPUs have one thread per physical core.

Multiple threads are useful for improving the performance of multi-threaded applications. Additional cores and their accompanying thread will always be beneficial for multi-threaded applications. Hyperthreading will be beneficial for applications optimized for it, but it may slow others down. For games, the number of threads is largely irrelevant, as long as you have at least 2 cores (preferably 4), and hyperthreading can sometimes even hit performance.

More important for gaming than the number of cores and threads is the clock rate. Problematically, unless the two CPUs are from the same family, this can only serve as a general guide and nothing like an exact comparison, because the clock cycles per instruction (CPI) will vary so much.

The FX-6100 and Athlon 64 FX-74 are not from the same family of CPUs, so their clock speeds are by no means directly comparable. Bear in mind, then, that while the FX-6100 has a 0.3 GHz faster frequency, this is not always an indicator that it will be superior in performance, despite frequency being crucial when trying to avoid GPU bottlenecking. As such, we need to look elsewhere for more reliable comparisons.

Aside from the clock rate, the next-most important CPU features for PC game performance are L2 and L3 cache size. Faster than RAM, the more cache available, the more data that can be stored for lightning-fast retrieval. L1 Cache is not usually an issue anymore for gaming, with most high-end CPUs eking out about the same L1 performance, and L2 is more important than L3 - but L3 is still important if you want to reach the highest levels of performance. Bear in mind that although it is better to have a larger cache, the larger it is, the higher the latency, so a balance has to be struck.

The FX-6100 has a 4096 KB bigger L2 cache than the Athlon 64 FX-74, and although the Athlon 64 FX-74 does not appear to have an L3 cache, its larger L2 cache means that it wins out in this area.

The maximum Thermal Design Power is the power in Watts that the CPU will consume in the worst case scenario. The lithography is the semiconductor manufacturing technology being used to create the CPU - the smaller this is, the more transistors that can be fit into the CPU, and the closer the connections. For both the lithography and the TDP, it is the lower the better, because a lower number means a lower amount of power is necessary to run the CPU, and consequently a lower amount of heat is produced.

The FX-6100 has a 30 Watt lower Maximum TDP than the Athlon 64 FX-74, and was created with a 58 nm smaller manufacturing technology. What this means is the FX-6100 will consume significantly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill significantly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

CPU Mini Review

Mini ReviewFX-6100 is a high-end CPU based on the 32nm Bulldozer architecture.

It offers 6 Physical Cores (6 Logical), initially clocked at 3.3GHz, which may go up to 3.6GHz and 8MB of L3 Cache.
Among its many features, Turbo Core and Virtualization are activated and the clock multiplier is unlocked, meaning it can be overclocked easily.

The processor DOES NOT integrated any graphics. and has a rated board TDP of 95W.

It is a powerful Hexa Core whose performance is good. It's thus capable of running most applications smoothly without any problem.
Athlon 64 FX-74 Dual Core is a middle-class Processor based on the 90nm K8 micro-architecture.

It offers 2 Physical Cores (2 Logical), clocked at 3.0GHz and 2MB of L2 Cache.
Among its many features, Virtualization is activated.

The processor DOES NOT integrate any graphics. and has a rated board TDP of 125W.

It offers average performance. This means it will become a bottleneck in some demanding applications.
Note: The rank of this processor is based on its Quad-Core Configuration.
