In terms of overall gaming performance, the Intel Pentium Dual Core B950 2.1GHz is noticeably better than the AMD APU A6-4455M Dual-Core 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 APU A6-4455M Dual-Core was released over a year more recently than the Pentium Dual Core, and so the APU A6-4455M Dual-Core is likely to have better levels of support, and will be more optimized for running the latest games.

The APU A6-4455M Dual-Core 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 APU A6-4455M Dual-Core 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 APU A6-4455M Dual-Core 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 APU A6-4455M Dual-Core and the Pentium Dual Core both have the same clock frequency, this is by no means an indicator that the two CPUs will provide the same level of performance. 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 APU A6-4455M Dual-Core has a 1536 KB bigger L2 cache than the Pentium Dual Core, and although the APU A6-4455M Dual-Core 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 APU A6-4455M Dual-Core has a 18 Watt lower Maximum TDP than the Pentium Dual Core (though they were created with the same size 32 nm manufacturing technology). What this means is the APU A6-4455M Dual-Core will consume slightly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill slightly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

The APU A6-4455M Dual-Core has an on-board GPU, which means that it will be capable of running basic graphics applications (i.e., games) without the need for a dedicated graphics card. The Pentium Dual Core, however, does not, and you will probably have to look for a dedicated card if you wish to use it at all.

On-board GPUs tend to be fairly awful in comparison to dedicated cards from the likes of AMD or Nvidia, but as they are built into the CPU, they also tend to be cheaper and require far less power to run (this makes them a good choice for laptops). We would recommend a dedicated card for running the latest games, but integrated GPUs are improving all the time and casual gamers may find less recent games perform perfectly acceptably.

CPU Mini Review

Mini ReviewHeterogeneous System Architecture ("HSA"), formerly known as Fusion System Architecture ("FSA"), is the marketing name for a series of APUs by AMD, aimed at providing good performance with low power consumption, and integrating a central processing unit (CPU) and graphics processing unit (GPU) based on a mobile stand-alone GPU. Fusion was announced in 2006 and has been in development since then. The final design is the product of the merger between AMD and ATI, combining general processor execution as well as 3D geometry processing and other functions of modern GPUs (like GPGPU computation) into a single die. This technology was shown to the general public in January 2011 at CES. Second-generation "Trinity" parts released in June 2012.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.
