CPU Mini Review

Mini Review The Core i5-9500 6-Core 3.0GHz is a mid-range CPU based on a refinement of the 14nm++ Coffee Lake microarchitecture. It is identical to the Core i5-9500F except it features integrated graphics. It offers 6 physical cores (6 logical), initially clocked at 3.0GHz, which may go up to 4.4GHz using 6 cores with Turbo Boost. The i5-9500 has 9MB of L3 Cache. This chip supports up to 128GB DDR-2666 MHz memory and features Intel UHD 630 integrated graphics. Among its many features, Turbo Boost 2.0, Optane Memory Support, and Virtualization are activated, and its multiplier is not unlocked. This Core i5-9500 CPU offers above average gaming performance and should not be the bottleneck in any modern gaming PC in 2019. It will be able to play all modern games at 60fps comfortably on ultra graphics performance at any supported resolution without being a hindrance to the accompanying GPU. However, performance may become bottlenecked if playing at 144Hz. The Ryzen R5 1400 is a high-end CPU based on AMD's 14nm, Zen microarchitecture. It offers 4 physical cores (8 logical), initially clocked at 3.2GHz, which may go up to 3.4GHz using Turbo Boost. It has an unlocked multiplier therefore it can be overclocked using traditional methods. It has 8MB of L3 Cache. Level 3 cache is a static memory bank of a processor and it is used to feed it instructions. This processor also supports DDR4 based RAMs with maximum memory support of 64GB. It has a maximum Thermal Power Design of 65W. It is on par with competitor processors. Among its many features, Simultaneous Multithreading, Cool n Quiet, CoolCore Technology, Extended Frequency Range (XFX), Pure Power and Precision Boost are enabled. It doesn't feature an integrated GPU. This CPU is likely to offer excellent computational performance and will not be the bottleneck in any modern gaming PC.

Gaming Performance Comparison

In terms of overall gaming performance, the Intel Core i5-9500 6-Core 3.0GHz is massively better than the AMD Ryzen R5 1400 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 i5-9500 6-Core 3.0GHz and the Ryzen R5 1400 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 6 has 2 more cores than the Ryzen R5 1400. 6 cores is probably excessive if you mean to just run the latest games, as games are not yet able to harness this many cores. The 4 cores in the Ryzen R5 1400 is more than enough for gaming purposes.

The Ryzen R5 1400 has 2 more threads than the Core i5-9500 6-Core. The Core i5-9500 6-Core has one thread per physical core, whereas the Ryzen R5 1400 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 i5-9500 6-Core and Ryzen R5 1400 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 Ryzen R5 1400 has a 0.5 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 6.

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'>Ryzen R5 1400</span> has a 512 KB bigger L2 cache than the <span class='gpu1Mention'>Core i5-9500 6-Core</span>, but on the other hand, it is the <span class='gpu1Mention'>Core i5-9500 6-Core</span> that has a 1 MB bigger L3 cache than the <span class='gpu2Mention'>Ryzen R5 1400</span>. In this case, the L2 size is probably what counts, so the <span class='gpu2Mention'>Ryzen R5 1400</span> is likely superior 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 Core i5-9500 6-Core and the Ryzen R5 1400 have the same TDP of 65 Watts, and were created with the same manufacturing size of 14 nm, which means they will affect your yearly electricity bill about equally.
