In terms of overall gaming performance, the Intel Atom Z2580 933MHz is very slightly 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 Atom Z2580 933MHz was released less than a year after the Celeron M ULV, and so they are likely to have similar levels of support, and similarly optimized performance when 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 Atom Z2580 933MHz has 1 more core than the Celeron M ULV. However, while the Atom Z2580 933MHz will probably perform better than the Celeron M ULV, 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 Celeron M ULV and Atom Z2580 933MHz 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 Z2580 933MHz has a 0.003 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 Atom Z2580 933MHz has a 1023 KB bigger L2 cache than the Celeron M ULV, but neither of the CPUs have L3 caches, so the Atom Z2580 933MHz 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.

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 rangeAtom Z2580 933MHz is Intel's latest addition to the Tablet word. It's a 4-threaded dual Core CPU based on a 32nm Cloverview architecture, clocked at 0.933GHz with very low TDP. It supports up to 2GB of DDR2-800 and features integrated graphics clocked at 533MHz.
