In terms of overall gaming performance, the AMD APU A4-4000 Dual-Core is noticeably better than the AMD Athlon II X2 245e 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 A4-4000 Dual-Core was released over three years more recently than the Athlon II X2, and so the APU A4-4000 Dual-Core is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Athlon II X2 when running the latest games.

The APU A4-4000 Dual-Core and the Athlon II X2 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 A4-4000 Dual-Core and the Athlon II X2 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 A4-4000 Dual-Core and Athlon II X2 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 A4-4000 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 Athlon II X2 has a 1024 KB bigger L2 cache than the APU A4-4000 Dual-Core, but neither of the CPUs have L3 caches, so the Athlon II X2 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 Athlon II X2 has a 20 Watt lower Maximum TDP than the APU A4-4000 Dual-Core. However, the APU A4-4000 Dual-Core was created with a 13 nm smaller manufacturing technology. Overall, by taking both into account, the APU A4-4000 Dual-Core is likely the CPU with the lower heat production and power requirements, but there really isn't much in it.

The APU A4-4000 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 Athlon II X2, 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 ReviewAPU A4-4000 Dual-Core is an entry-level CPU based on the 32nm, Piledriver architecture.

It offers 2 Physical Cores (2 Logical), initially clocked at 3.0GHz, which may go up to 3.2GHz and 1MB of L2 Cache.
Among its many features, Turbo Core and Virtualization are activated.

The processor integrates very weak Graphics called Radeon HD 7480D, with 128 Shader Processing Units, clocked at 720MHz, which share the L2 Cache and system RAM with the processor.
Both the processor and integrated graphics have a rated board TDP of 65W.

Its performance is below the average and so most demanding games will not run optimally.
The Athlon II series is based on the AMD K10 architecture and derived from the Phenom II series. However, unlike its Phenom siblings, it does not contain any L3 Cache. There are two Athlon II dies: the dual-core Regor die with 1 MB L2 Cache per core and the four-core Propus with 512 KB per core. Regor is a native dual-core design with lower TDP and additional L2 to offset the removal of L3 cache. The three core Rana is derived from the Propus quad-core design, with one core disabled.
