In terms of overall gaming performance, the AMD Athlon Neo X2 Dual Core L325 is noticeably better than the Intel Pentium 4 Mobile 2.8GHz 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 Athlon Neo X2 was released over three years more recently than the Pentium 4 Mobile, and so the Athlon Neo X2 is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Pentium 4 Mobile when running the latest games.

The Athlon Neo X2 has 1 more core than the Pentium 4 Mobile. However, while the Athlon Neo X2 will probably perform better than the Pentium 4 Mobile, both CPUs are likely to struggle with the latest games, and will almost certainly bottleneck high-end graphics cards. This should not affect games that are a few years old, and even the latest games should at least be playable on very low settings, as only recently have game developers begun to harness the power of multiple cores.

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 Neo X2 and Pentium 4 Mobile 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 Pentium 4 Mobile has a 1.3 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 probably a good indicator that the Athlon Neo X2 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 Athlon Neo X2 and the Pentium 4 Mobile have the same L2 cache size, and neither CPU appears to have an L3 cache. In this case, the Athlon Neo X2 has a 240 KB bigger L1 cache, so would probably provide better performance than the Pentium 4 Mobile, 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.

The Athlon Neo X2 has a 70 Watt lower Maximum TDP than the Pentium 4 Mobile, and was created with a 25 nm smaller manufacturing technology. What this means is the Athlon Neo X2 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 ReviewWith 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.The Mobile Intel Pentium 4 Processor was released to address the problem of putting a full desktop Pentium 4 processor into a laptop, which some manufacturers were doing. The Mobile Pentium 4 used a 533 MHz FSB, following the desktop Pentium 4's evolution. Oddly, increasing the bus speed by 133 MHz (33 MHz core) caused a massive increase in TDPs, as mobile Pentium 4 processors gave off 59.8 W - 70 W of heat, with the Hyper-Threading variants giving off 66.1 W - 88 W. This allowed the mobile Pentium 4 to bridge the gap between the desktop Pentium 4 (giving off 115 W maximum), and the Pentium 4-M (giving off 35 W maximum).
