In terms of overall gaming performance, the AMD Sempron 2650 is very slightly better than the AMD Athlon 64 FX-53 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 Sempron 2650 was released over three years more recently than the Athlon 64 FX-53, and so the Sempron 2650 is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Athlon 64 FX-53 when running the latest games.

The Sempron 2650 has 1 more core than the Athlon 64 FX-53. However, while the Sempron 2650 will probably perform better than the Athlon 64 FX-53, both CPUs are likely to struggle with the latest games, and will almost certainly bottleneck high-end graphics cards. Both CPUs also have quite low clock frequencies, which means recent games will have to be played at low settings, assuming you own an equivalently powerful GPU.

The Sempron 2650 has 1 more threads than the Athlon 64 FX-53. 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 Sempron 2650 and Athlon 64 FX-53 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 Athlon 64 FX-53 has a 1.1 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. In this case, however, the difference is probably a good indicator that the Sempron 2650 is superior.

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 Sempron 2650 and the Athlon 64 FX-53 have the same L2 cache size, and neither CPU appears to have an L3 cache. They even have the same L1 cache size, so are identical in terms of cache size.

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 Sempron 2650 has a 64 Watt lower Maximum TDP than the Athlon 64 FX-53, and was created with a 102 nm smaller manufacturing technology. What this means is the Sempron 2650 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).

The Sempron 2650 has an on-board GPU, which means that it will be capable of running basic graphics applications (i.e., games) without the need for a dedicated graphics card. The Athlon 64 FX-53, however, does not, and you will probably have to look for a dedicated card if you wish to use it at all.

On-board GPUs tend to be fairly awful in comparison to dedicated cards from the likes of AMD or Nvidia, but as they are built into the CPU, they also tend to be cheaper and require far less power to run (this makes them a good choice for laptops). We would recommend a dedicated card for running the latest games, but integrated GPUs are improving all the time and casual gamers may find less recent games perform perfectly acceptably.

CPU Mini Review

Mini ReviewSempron 2650 is a low-budget dual-core processor based on the Jaguar microarchitecture.
Sempron 2650 packs 2 Kabini Cores, clocked at 1.45GHz and very weak integrated graphics called Radeon HD 8240 that offer 128 Shader Processing Units and come clocked at 400MHz. The rated TDP is of 25W, thus the processor is suited for weaker systems.
The performance of the processor is quite limited, while the integrated graphics can only run most modern games at the lowest settings.
Athlon 64 FX-53 is an entry-level Processor based on the 130nm K8 micro-architecture.

It offers 1 Physical Core (1 Logical), clocked at 2.4GHz and 1MB of L2 Cache.
No relevant technologies are activated in a way the processor doesn't even support Virtualization.

The processor DOES NOT integrate any graphics. and has a rated board TDP of 89W.

Its performance is below the average and so most demanding games will not run optimally.
