In terms of overall gaming performance, the Intel Celeron M 575 2.0GHz is marginally better than the Intel Pentium M 2.13GHz 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 575 was released less than a year after the Pentium M 2.13GHz, 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 Pentium M 2.13GHz and the Celeron M 575 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 Pentium M 2.13GHz and the Celeron M 575 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 Pentium M 2.13GHz and Celeron M 575 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 M 2.13GHz has a 0.13 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 Pentium M 2.13GHz has a 1024 KB bigger L2 cache than the Celeron M 575, but neither of the CPUs have L3 caches, so the Pentium M 2.13GHz 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 Pentium M 2.13GHz has a 4 Watt lower Maximum TDP than the Celeron M 575. However, the Celeron M 575 was created with a 25 nm smaller manufacturing technology. Overall, by taking both into account, the Celeron M 575 is likely the CPU with the lower heat production and power requirements, by quite a wide margin.

CPU Mini Review

Mini ReviewPentium M 2.13GHz based on the Dothan architecture is a single core Mobile CPU with its roots on the Pentium III and Pentium 4 that delivers very limited performance for any of today's games.Merom is the code name for various Intel processors that are sold as Core 2 Duo, Core 2 Solo, Pentium Dual-Core and Celeron. It was the first mobile processor to be based on the Core microarchitecture, replacing the Enhanced Pentium M based Yonah processor. Merom has product code 80537, which is shared with Merom-2M and Merom-L that are very similar but have a smaller L2 cache. Merom-L has only one processor core and a different CPUID model. The desktop version of Merom is Conroe and the dual-socket server version is Woodcrest. Merom has subsequently been replaced by Penryn.
