In terms of overall gaming performance, the AMD Athlon Neo X2 Dual Core L325 is noticeably better than the Intel Atom D425 1.8GHz 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 Atom D425 1.8GHz was released over a year more recently than the Athlon Neo X2, and so the Atom D425 1.8GHz is likely to have better levels of support, and will be more optimized for running the latest games.

The Athlon Neo X2 has 1 more core than the Atom D425 1.8GHz. However, while the Athlon Neo X2 will probably perform better than the Atom D425 1.8GHz, 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.

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 Atom D425 1.8GHz 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 Atom D425 1.8GHz 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. In this case, however, the difference is enough that it possibly indicates the superiority of the Athlon Neo X2.

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 Neo X2 has a 512 KB bigger L2 cache than the Atom D425 1.8GHz, but neither of the CPUs have L3 caches, so the Athlon Neo X2 wins out in this area with its larger L2 cache.

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 Atom D425 1.8GHz has a 8 Watt lower Maximum TDP than the Athlon Neo X2, and was created with a 20 nm smaller manufacturing technology. What this means is the Atom D425 1.8GHz will consume slightly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill slightly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

CPU Mini Review

Mini ReviewAtom processors are based on the Bonnell microarchitecture. On 21 December 2009, Intel announced the Pine Trail platform, including new Atom processor code-named Pineview (Atom N450), with total kit power consumption down 20%. On 28 December 2011, Intel updated the Atom line with the Cedar processors.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.
