CPU Mini Review

Mini Review The Intel Core i5-5575R 4-Core 2.8GHz is a Performance CPU based on the 14nm Broadwell MicroArchitecture. It offers 4 Physical Cores (4 Logical), initially clocked at 2.8GHz, which may go up to 3.3GHz and 4MB of L3 Cache. Among its many features, HyperThreading, Turbo Boost 2.0 and Virtualization are activated and the processor has its multiplier unlocked. The processor integrates low-end integrated graphics called Intel Iris Pro Graphics 6200 with 48 Execution Units, initially clocked at 300MHz and that go up to 1150MHz, in Turbo Mode which shares 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 mid-range, although it should fast enough to run most modern AAA games without impacting performance. Core i3-4360 3.7GHz is a middle-class CPU based on the 22nm, Haswell architecture. <br/> <br/> It offers 2 Physical Cores (4 Logical), clocked at 3.7GHz and 4MB of L3 Cache. <br/> Among its many features, <b>Turbo Boost and HyperThreading</b> are activated. <br/> <br/> The processor integrates powerful Graphics called <b>Intel HD Graphics 4600</b>, with 20 Execution Units, initially clocked at 350MHz and that go up to 1150MHz, in Turbo Mode which share the L2 Cache and system RAM with the processor. <br/> Both the processor and integrated graphics have a rated board TDP of 54W. <br/> <br/> It is a powerful processor whose performance is good. It's thus capable of running most applications smoothly without any problem.

Gaming Performance Comparison

In terms of overall gaming performance, the Intel Core i5-5575R 4-Core 2.8GHz is massively better than the Intel Core i3-4360 3.7GHz 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 i5-5575R 4-Core 2.8GHz and the Core i3-4360 3.7GHz were released at the same time, so are likely to be quite similar.

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 4 has 2 more cores than the Core i3-4360 3.7GHz. { With 4 cores, the 4 is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

Both the Intel Core i5-5575R 4-Core 2.8GHz and the Intel Core i3-4360 3.7GHz have the same number of threads. The Core i5-5575R 4-Core has one thread per physical core, whereas the Core i3-4360 3.7GHz 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 i5-5575R 4-Core and Core i3-4360 3.7GHz 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 i3-4360 3.7GHz has a 0.9 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 4 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 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.
