In terms of overall gaming performance, the Intel Pentium Dual Core 3550M 2.3GHz 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 3550M 2.3GHz was released over a year more recently than the B950 2.1GHz, and so the 3550M 2.3GHz is likely to have better levels of support, and will be more optimized for running the latest games.

The 3550M 2.3GHz 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 3550M 2.3GHz 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 3550M 2.3GHz 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 3550M 2.3GHz has a 0.2 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 3550M 2.3GHz has a 512 KB bigger L2 cache than the B950 2.1GHz, and the two CPUs have the same L3 cache size, so the 3550M 2.3GHz 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 B950 2.1GHz has a 2 Watt lower Maximum TDP than the 3550M 2.3GHz. However, the 3550M 2.3GHz was created with a 10 nm smaller manufacturing technology. Overall, by taking both into account, the 3550M 2.3GHz is likely the CPU with the lower heat production and power requirements, by a small amount.

CPU Mini Review

Mini ReviewPentium Dual Core 3550M 2.3GHz is a budget processor, part of the Haswell Refresh CPUs released in April of 2014.
Based on 22nm architecture, the Pentium Dual Core 3550M 2.3GHz has many of the Haswell features disabled, including Hyper and Multi Treading. The Processor should not consume more than 37 Watts.
This CPU is clocked at 2.3GHz and comes with a weak Intel HD (Haswell) mobile chip which raises to 1100MHz in Turbo Mode and will only be seen in smaller cheaper notebooks.
Its performance is average and will only provide modest gaming though most modern demanding games will run fluently.
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.
