CPU Mini Review

Mini Review The Intel Core i3-8000 4-Core 3.6GHz is a mid-range CPU based on Intel's 8th Gen 14nm Coffee Lake S microarchitecture. It offers 4 physical cores (4 logical), initially clocked at 3.6GHz across all four cores. The i3-8000 doesn't have an unlocked multiplier, therefore, it can't be overclocked using traditional methods. It has 6MB 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. The Core i3-8000 has support for up to 64GB of dual-channel DDR4-2400 memory. Among its many features are Intel Enhanced Speedstep, Turbo Boost 2.0, Virtualization, SSE3, AVX2 and SSE 4.2. It integrates Intel UHD Graphics 630 on board. It has a base frequency of 350MHz which can go up to 1.1GHz, as well as offering DirectX 12 support. This CPU is likely to middling computational performance and could become a bottleneck in some of the most CPU-intensive AAA games in 2018. Core i5-4590T 2.0GHz is a super energy efficient CPU based on the 22nm, Haswell architecture. <br/> <br/> It offers 4 Physical Cores (4 Logical), initially clocked at 2.0GHz, which may go up to 3.0GHz and 6MB of L3 Cache. <br/> Among its many features, <b>Turbo Boost and Virtualization</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 65W. <br/> <br/> Its performance is very good and sufficient for extreme gaming.

Gaming Performance Comparison

In terms of overall gaming performance, the Intel Core i3-8000 4-Core 3.6GHz is massively better than the Intel Core i5-4590T 2.0GHz 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 i3-8000 4-Core 3.6GHz and the Core i5-4590T 2.0GHz 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 Core i3-8000 4-Core and the Core i5-4590T 2.0GHz both have 4 cores, which is not likely to be a limiting factor for gaming.

Both the Intel Core i3-8000 4-Core 3.6GHz and the Intel Core i5-4590T 2.0GHz 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 Core i3-8000 4-Core and Core i5-4590T 2.0GHz 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 i3-8000 4-Core has a 1.6 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 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 Core i3-8000 4-Core and the Core i5-4590T 2.0GHz have the same L2 cache size, and the same L3 cache size, so in terms of cache-related gaming performance, we have to look back to the clock rate, where the Core i3-8000 4-Core wins out.

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.
