In terms of overall gaming performance, the Intel Atom N270 1.6GHz is marginally better than the Intel Celeron M ULV 523 930MHz 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 Celeron M ULV was released over a year more recently than the Atom N270 1.6GHz, and so the Celeron M ULV is likely to have better levels of support, and will be more optimized for running the latest games.

Both CPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful CPUs. Neither of these will be able to run the latest games in any playable way.

The Celeron M ULV and the Atom N270 1.6GHz both have 1 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 Celeron M ULV and the Atom N270 1.6GHz 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 Celeron M ULV and Atom N270 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 Atom N270 1.6GHz has a 0.67 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 Atom N270 1.6GHz has a 511 KB bigger L2 cache than the Celeron M ULV, but neither of the CPUs have L3 caches, so the Atom N270 1.6GHz 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 N270 1.6GHz has a 52 Watt lower Maximum TDP than the Celeron M ULV, and was created with a 20 nm smaller manufacturing technology. What this means is the Atom N270 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 Celeron brand has been used by Intel for several distinct ranges of x86 CPUs targeted at budget personal computers. Celeron processors can run all IA-32 computer programs, but their performance is somewhat lower when compared to similar CPUs with higher-priced Intel CPU brands. For example, the Celeron brand will often have less cache memory, or have advanced features purposely disabled. These missing features have had a variable impact on performance. In some cases, the effect was significant and in other cases the differences were relatively minor. Many of the Celeron designs have achieved a very high bang for the buck, while at other times, the performance difference has been noticeable. This has been the primary justification for the higher cost of other Intel CPU brands versus the Celeron rangeIntel 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.
