In terms of overall gaming performance, the AMD Phenom II X4 905e is massively better than the AMD Athlon 5350 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 Athlon 5350 was released over three years more recently than the Phenom II X4, and so the Athlon 5350 is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Phenom II X4 when running the latest games.

The Athlon 5350 and the Phenom II X4 both have 4 cores, which is not likely to be a limiting factor for gaming.

Both the AMD Athlon 5350 and the AMD Phenom II X4 905e have the same number of threads. 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 Athlon 5350 and Phenom II X4 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 Phenom II X4 has a 0.45 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 enough that it possibly indicates the superiority of the .

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 Athlon 5350 and the Phenom II X4 have the same L2 cache size, but the Athlon 5350 does not appear to have an L3 cache, so the Phenom II X4 definitely 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 Athlon 5350 has a 40 Watt lower Maximum TDP than the Phenom II X4, and was created with a 17 nm smaller manufacturing technology. What this means is the Athlon 5350 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 Athlon 5350 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 Phenom II X4, 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 ReviewAthlon 5350 is a low-budget quad-core processor based on the Jaguar microarchitecture.
Athlon 5350 packs 4 Kabini Cores, clocked at 2.05GHz and weak integrated graphics called Radeon HD 8400 that offer 128 Shader Processing Units and come clocked at 600MHz. The rated TDP is of 25W, thus the processor is suited for weaker systems.
The performance of the processor is quite average, while the integrated graphics can only run most modern games at the lowest settings.
Phenom II X4 905e is an energy efficient processor based on the 45nm, K10 architecture.

It offers 4 Physical Cores (4 Logical), clocked at 2.5GHz and 6MB of L3 Cache.
Among its many features, Virtualization is activated and the clock multiplier is unlocked, meaning it can be overclocked easily.

The processor DOES NOT integrate any graphics. and has a rated board TDP of 65W.

It offers average performance. This means it will become a bottleneck in some demanding applications.
