In terms of overall gaming performance, the Intel Atom 330 1.6GHz is very slightly better than the Intel Pentium 4 Mobile 3.2GHz 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 330 1.6GHz was released less than a year after the Pentium 4 Mobile, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Atom 330 1.6GHz has 1 more core than the Pentium 4 Mobile. However, while the Atom 330 1.6GHz 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 Pentium 4 Mobile and Atom 330 1.6GHz 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 1.6 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 Atom 330 1.6GHz 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 Pentium 4 Mobile has a 1023 KB bigger L2 cache than the Atom 330 1.6GHz, but neither of the CPUs have L3 caches, so the Pentium 4 Mobile 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 330 1.6GHz has a 80 Watt lower Maximum TDP than the Pentium 4 Mobile, and was created with a 45 nm smaller manufacturing technology. What this means is the Atom 330 1.6GHz 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 ReviewThe 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).Intel Atom is the brand name for a line of ultra-low-voltage x86 and x86-64 CPUs (or microprocessors) from Intel, designed in 45 nm CMOS and used mainly in netbooks, nettops, and Mobile Internet devices (MIDs)
Intel Atom is a direct successor of the Intel A100 and A110 low-power microprocessors (code-named Stealey), which were built on a 90 nm process, had 512 KB L2 cache and run at 600 MHz/800 MHz with 3W TDP (Thermal Design Power). Prior to the Silverthorne announcement, outside sources had speculated that Atom would compete with AMD's Geode system-on-a-chip processors, used by the One Laptop per Child project, and other cost- and power-sensitive applications for x86 processors. However, Intel revealed on October 15, 2007 that it was developing another new mobile processor, codenamed Diamondville, for OLPC-type devices.
