In terms of overall gaming performance, the AMD Athlon Neo X2 Dual Core L325 is marginally better than the AMD APU E-450 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 APU E-450 Dual was released over a year more recently than the Athlon Neo X2, and so the APU E-450 Dual is likely to have better levels of support, and will be more optimized for running the latest games.

The APU E-450 Dual and the Athlon Neo X2 both have 2 cores, and so are quite likely to struggle with the latest games, or at least bottleneck high-end graphics cards when running them. With a decent accompanying GPU, the APU E-450 Dual and the Athlon Neo X2 may still be able to run slightly older games fairly effectively.

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 APU E-450 Dual and Athlon Neo X2 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 APU E-450 Dual has a 0.15 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 APU E-450 Dual and the Athlon Neo X2 have the same L2 cache size, and neither CPU appears to have an L3 cache. In this case, the Athlon Neo X2 has a 128 KB bigger L1 cache, so would probably provide better performance than the APU E-450 Dual, at least 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.

Both the APU E-450 Dual and the Athlon Neo X2 have the same TDP of 18 Watts, but the APU E-450 Dual has a lower lithography size, and so will affect your yearly electricity bills less adversely.

The APU E-450 Dual 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 Neo X2, 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 ReviewAMD Fusion APUs enable visually rich, next-generation, enhanced PC experiences even on small form factor devices while facilitating extended real-world battery life. Go mobile in style with super-sleek notebooks and "all-day" battery life with AMD AllDay Power built on VISION Technology from AMD. Share full HD content effortlessly as you experience responsive performance for the software of today and tomorrow.With 27 mm 27 mm in size and 2.5 mm in thickness, the Athlon Neo processors utilize a new package called "ASB1", essentially a BGA package, for smaller footprint to allow smaller designs for notebooks and lowering the cost. The clock of the processors is significantly lower than desktop and other mobile counterparts to reach a low TDP, at 15W maximum for a single core x86-64 CPU at 1.6 GHz. The Athlon Neo processors are equipped with 512 KB of L2 cache and HyperTransport 1.0 running at 800 MHz frequency.
