In terms of overall gaming performance, the Intel Core i5-4302Y 1.6GHz 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 Core i5-4302Y 1.6GHz was released over a year more recently than the Pentium Dual Core, and so the Core i5-4302Y 1.6GHz is likely to have better levels of support, and will be more optimized for running the latest games.

The Core i5-4302Y 1.6GHz and the Pentium Dual Core 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 Core i5-4302Y 1.6GHz and the Pentium Dual Core 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 Core i5-4302Y 1.6GHz and Pentium Dual Core 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 Dual Core has a 0.5 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 Core i5-4302Y 1.6GHz and the Pentium Dual Core have the same L2 cache size, but the Core i5-4302Y 1.6GHz has a 1 MB bigger L3 cache, so in this area, it wins out over the Pentium Dual Core.

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 Core i5-4302Y 1.6GHz has a 23 Watt lower Maximum TDP than the Pentium Dual Core, and was created with a 10 nm smaller manufacturing technology. What this means is the Core i5-4302Y 1.6GHz will consume significantly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill significantly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

CPU Mini Review

Mini ReviewCore i5-4302Y is an energy efficient dual core processor clocked at 1.6 GHz and can go up to 2.3 GHz using turbo boost under extreme loads. It has an extremely low TDP of 11.5 watts.It equips an HD 4400 iGPU with 200 MHz base clock and 850 MHz turbo boost clock It's performance is average and only suited for non-demanding applications and games.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.
