In terms of overall gaming performance, the Intel Pentium Dual Core B950 2.1GHz is marginally better than the AMD Phenom II X3 P860 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 Pentium Dual Core was released less than a year after the Phenom II X3, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Phenom II X3 has 1 more core than the Pentium Dual Core. However, while the Phenom II X3 will probably perform better than the Pentium Dual Core, both CPUs are likely to struggle with the latest games, and will almost certainly bottleneck high-end graphics cards. Both CPUs also have quite low clock frequencies, which means recent games will have to be played at low settings, assuming you own an equivalently powerful GPU.

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 Phenom II X3 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 0.1 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 Phenom II X3 has a 1053 KB bigger L2 cache than the Pentium Dual Core, and although the Phenom II X3 does not appear to have an L3 cache, its larger L2 cache means that it wins out in this area.

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 Phenom II X3 has a 10 Watt lower Maximum TDP than the Pentium Dual Core. However, the Pentium Dual Core was created with a 13 nm smaller manufacturing technology. Overall, by taking both into account, the Pentium Dual Core is likely the CPU with the lower heat production and power requirements, by a small amount.

CPU Mini Review

Mini ReviewPhenom II X3 P860 is a triple core mobile CPU based on the Champlain Core and therefore related to the Athlon II X3 Desktop Series.
It features 3 cores, clocked 2.0GHz and the fastest supported memory is DDR3-1066.
Its performance is average and decent enough to run most games at high settings fluently, if paired with the appropriate GPU, obviously. However, the most demanding games will require reduced settings to be played optimally.
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.
