In terms of overall gaming performance, the AMD Athlon 300U 2-Core 2.4 GHz is noticeably better than the Intel Core i5-6260U 1.8GHz 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 Athlon 300U 2-Core was released over three years more recently than the Core i5-6260U 1.8GHz, and so the Athlon 300U 2-Core is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Core i5-6260U 1.8GHz when running the latest games.

Both CPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings (assuming they are accompanied by equivalently powerful GPUs).

The Athlon 300U 2-Core and the Core i5-6260U 1.8GHz 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 Athlon 300U 2-Core and the Core i5-6260U 1.8GHz may still be able to run slightly older games fairly effectively.

Both the AMD Athlon 300U 2-Core 2.4 GHz and the Intel Core i5-6260U 1.8GHz have the same number of threads. Both the Athlon 300U 2-Core and the Core i5-6260U 1.8GHz use hyperthreading. The Athlon 300U 2-Core has 2 logical threads per physical core and the Core i5-6260U 1.8GHz has 2.

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 Athlon 300U 2-Core and Core i5-6260U 1.8GHz 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 Athlon 300U 2-Core has a 0.6 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 Athlon 300U 2-Core has a 512 KB bigger L2 cache than the Core i5-6260U 1.8GHz, and the two CPUs have the same L3 cache size, so the Athlon 300U 2-Core 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.

Both the Athlon 300U 2-Core and the Core i5-6260U 1.8GHz have the same TDP of 15 Watts, but the Athlon 300U 2-Core has a lower lithography size, and so will affect your yearly electricity bills less adversely.

The Core i5-6260U 1.8GHz 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 300U 2-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 ReviewThe Athlon 300U 2-Core 2.4 GHz is a budget notebook APU based on AMD's 12nm Zen+ microarchitecture. It offers 2 physical cores (4 logical), clocked at 2.4 GHz base clock speed and 3.3 GHz boost clock speed. It's the first mobile Athlon processor in eight years. It has a locked multiplier and therefore cannot overclocked using traditional methods. It has 4MB of L3 Cache. Level 3 cache is a static memory bank of a processor and it is used to feed it instructions. It also has 1MB L2 Cache and 192KB L1 Cache. This processor also supports DDR4 based RAMs with maximum memory support of 32GB. The AMD Athlon 300U has a maximum Thermal Power Design of 15W, making it a low-end, power-efficient CPU that should extend laptop battery life. Among its many features are Cool n Quiet, CoolCore Technology, Extended Frequency Range (XFX), Pure Power and Precision Boost are enabled. It features an integrated Vega 3 GPU with 3 Execution units, 192 Shaders, and a maximum clock speed of 1,000MHz. This is a low-end graphics chip that can run less demanding eSports titles at 720p.Core i5-6260U 1.8GHz is a Super Energy Efficient, Performance Mobile Processor, based on the 14nm Skylake MicroArchitecture.

It offers 2 Physical Cores (4 Logical), initially clocked at 1.8GHz, which may go up to 2.9GHz and 4MB of L3 Cache.
Among its many features, HyperThreading, Turbo Boost 2.0 and Virtualization are activated.

The Processor Integrates Very Powerful Graphics called Intel Iris i5 6260U, with 48 Execution Units, initially clocked at 300MHz and that go up to 950MHz, in Turbo Mode which share the L Caches and System RAM with the processor.
