In terms of overall gaming performance, the AMD Sempron M120 is very slightly better than the Intel Celeron M 390 1.7GHz 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 Sempron M120 was released less than a year after the Celeron M 390, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Celeron M 390 and the Sempron M120 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 390 and the Sempron M120 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 390 and Sempron M120 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 Sempron M120 has a 0.4 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 Sempron M120 has a 511 KB bigger L2 cache than the Celeron M 390, but neither of the CPUs have L3 caches, so the Sempron M120 wins out in this area with its larger L2 cache.

The System Bus Speed is important for providing higher bandwidth, and with higher bandwidth the system has the capacity to move more data over a certain time period than it would with lower bandwidth.

The Sempron M120 has a 2800 MHz faster System Bus Speed than the Celeron M 390, and as such, has a massively higher limit when it comes to the size of the data being processed at once.

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 Celeron M 390 has a 4 Watt lower Maximum TDP than the Sempron M120. However, the Sempron M120 was created with a 45 nm smaller manufacturing technology. Overall, by taking both into account, the Sempron M120 is likely the CPU with the lower heat production and power requirements, by quite a wide margin.

CPU Mini Review

Mini ReviewThe Celeron is a family of microprocessors from Intel targeted at the low-end consumer market. CPUs in the Celeron brand have used designs from sixth- to eighth-generation CPU microarchitectures. [Please be aware that GD data is constantly refined as more information and reports are made available.]Sempron has been the marketing name used by AMD for several different budget desktop CPUs, using several different technologies and CPU socket formats. The Sempron replaced the AMD Duron processor and competes against Intel's Celeron series of processors. AMD coined the name from the Latin semper, which means always, to suggest the Sempron is suitable for daily use, practical, and part of everyday life.
