CPU Mini Review

Mini Review The AMD APU A10-9700 4-Core 3.5GHz is a budget APU based on AMD's 28nm Excavator microarchitecture. It offers 4 physical cores (4 logical) initially clocked at 3.5GHz, rising to 3.8GHz in boost mode. It has an unlocked multiplier and therefore can overclocked using traditional methods. It has 2MB of L2 Cache. This processor also supports DDR4 based RAMs with maximum memory support of 64GB. It has a maximum Thermal Power Design of 65W, making it an averagely power efficient CPU. Among its many features are Cool n Quiet, CoolCore Technology, Extended Frequency Range (XFX), Pure Power and Precision Boost are enabled. The APU A10-9700 4-Core 3.5GHz features integrated Radeon R7 3rd Gen GCN graphics with 512 Shaders and a maximum clock speed of 1,029MHz. This is a low-end graphics chip that will struggle to run any modern game at 720p. Phenom II X4 905e is an energy efficient processor based on the 45nm, K10 architecture. <br/> <br/> It offers 4 Physical Cores (4 Logical), clocked at 2.5GHz and 6MB of L3 Cache. <br/> Among its many features, <b>Virtualization</b> is activated and the clock multiplier is unlocked, meaning it can be overclocked easily. <br/> <br/> The processor DOES NOT integrate any graphics. and has a rated board TDP of 65W. <br/> <br/> It offers average performance. This means it will become a bottleneck in some demanding applications.

Gaming Performance Comparison

In terms of overall gaming performance, the AMD APU A10-9700 4-Core 3.5GHz is massively better than the AMD Phenom II X4 905e 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.

Both the APU A10-9700 4-Core 3.5GHz and the Phenom II X4 905e were released at the same time, so are likely to be quite similar.

{ The APU A10-9700 4-Core and the Phenom II X4 both have 4 cores, which is not likely to be a limiting factor for gaming.

Both the AMD APU A10-9700 4-Core 3.5GHz and the AMD Phenom II X4 905e have the same number of threads. Both CPUs have one thread per physical core.

Multiple threads are useful for improving the performance of multi-threaded applications. Additional cores and their accompanying thread will always be beneficial for multi-threaded applications. Hyperthreading will be beneficial for applications optimized for it, but it may slow others down. For games, the number of threads is largely irrelevant, as long as you have at least 2 cores (preferably 4), and hyperthreading can sometimes even hit performance.

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 A10-9700 4-Core and Phenom II X4 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 A10-9700 4-Core has a 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. In this case, however, the difference is probably a good indicator that the is superior.

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 A10-9700 4-Core and the Phenom II X4 have the same L2 cache size, but the APU A10-9700 4-Core does not appear to have an L3 cache, so the Phenom II X4 definitely 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.

Both the APU A10-9700 4-Core and the Phenom II X4 have the same TDP of 65 Watts, but the APU A10-9700 4-Core has a lower lithography size, and so will affect your yearly electricity bills less adversely.
