In terms of overall gaming performance, the Intel Pentium Dual Core 2030M 2.5GHz is noticeably better than the Intel Pentium Dual Core B950 2.1GHz 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 2030M 2.5GHz was released over a year more recently than the B950 2.1GHz, and so the 2030M 2.5GHz is likely to have better levels of support, and will be more optimized for running the latest games.

The 2030M 2.5GHz and the B950 2.1GHz both have 2 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 2030M 2.5GHz and the B950 2.1GHz 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 2030M 2.5GHz and B950 2.1GHz 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 2030M 2.5GHz 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 2030M 2.5GHz and the B950 2.1GHz have the same L2 cache size, and the same L3 cache size, so in terms of cache-related gaming performance, the two CPUs are too similar to judge.

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.

Both the 2030M 2.5GHz and the B950 2.1GHz have the same TDP of 35 Watts, but the 2030M 2.5GHz has a lower lithography size, and so will affect your yearly electricity bills less adversely.

CPU Mini Review

Mini ReviewPentium Dual Core 2030M 2.5GHz is a Dual-Core processor for budget oriented - entry - level laptops, based on the 22nm, Ivy Bridge micro-architecture.
Though based on the Ivy Bridge architecture, important features such as Turbo Boost and Hyper-Threading are deactivated. It offers 2MB of L3 Cache and integrated graphics called Intel HD 2500, clocked at 650 MHz (up to 1100 MHz in Turbo Mode). The Memory Controller supports DDR3-1333 and DDR3-1600 memory types. It should consume no more than 35 Watt.
Its performance is quite average and behind entry-level i7 laptop processors and so it's best paired with entry and middle class level GPUs.
Pentium Dual Core B950 2.1GHz is an entry-level CPU part of the Pentium Dual Core Series release by Intel.
It's based on the Sandy Bridge architecture but many of the special technologies are deactivated and has 2 cores, whereas each core only has one thread.
The performance is average and enough to play Very Demanding games smoothly, at least with medium detail.
