CPU Mini Review

Mini Review Core i5-6300U 2.0GHz is a Super Energy Efficient, Performance Mobile Processor, based on the 14nm Skylake MicroArchitecture. <br/> <br/> It offers 2 Physical Cores (4 Logical), initially clocked at 2.0GHz, which may go up to 3.1GHz and 4MB of L3 Cache. <br/> Among its many features, <b>HyperThreading, Turbo Boost 2.0 and Virtualization</b> are activated. <br/> <br/> The Processor Integrates Very Powerful Graphics called <b>Intel Iris i5 6360U</b>, with 48 Execution Units, initially clocked at 300MHz and that go up to 1000MHz, in Turbo Mode which share the L Caches and System RAM with the processor. <br/> Both the processor and integrated graphics have a rated board TDP of 15W. <br/> <br/> It is a powerful processor whose performance is good. It's thus capable of running most applications smoothly without any problem. Core i7-720QM 4-Core 1.60GHz is a high-end mobile CPU based on the 45nm, Nehalem architecture. <br/> <br/> It offers 4 Physical Cores (8 Logical), initially clocked at 1.6GHz, which may go up to 2.8GHz and 6MB of L3 Cache. <br/> Among its many features, <b>HyperThreading, Turbo Boost and Virtualization</b> are activated. <br/> <br/> The processor DOES NOT integrated any graphics and has a rated board TDP of 45W. <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 Intel Core i5-6360U 2.0GHz is significantly better than the Intel Core i7-720QM 4-Core 1.60GHz 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 Core i5-6360U 2.0GHz and the Core i7-720QM 4-Core 1.60GHz were released at the same time, so are likely to be quite similar.

{ The Core i5-6360U 2.0GHz and the Core i7-720QM 4-Core both have 4 cores, which is not likely to be a limiting factor for gaming.

The Core i7-720QM 4-Core has 4 more threads than the Core i5-6360U 2.0GHz. The Core i5-6360U 2.0GHz has one thread per physical core, whereas the Core i7-720QM 4-Core uses hyperthreading and has 2 logical threads 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 Core i5-6360U 2.0GHz and Core i7-720QM 4-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 Core i5-6360U 2.0GHz has a 0.4 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 <span class='gpu2Mention'>Core i7-720QM 4-Core</span> has a 512 KB bigger L2 cache than the <span class='gpu1Mention'>Core i5-6360U 2.0GHz</span>, which means that it, at worst, wins out in this area, and at best, will provide superior gaming performance and will work much better with high-end graphics cards.

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.
