In terms of overall gaming performance, the Intel Core i3-7100 2-Core 3.9GHz is massively better than the AMD Opteron 2387 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 Opteron 2387 was released less than a year after the Core i3-7100 2-Core, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Opteron 2387 has 2 more cores than the Core i3-7100 2-Core. With 4 cores, the Opteron 2387 is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

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 i3-7100 2-Core and Opteron 2387 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 i3-7100 2-Core has a 1.1 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 Opteron 2387 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 i3-7100 2-Core and the Opteron 2387 have the same L2 cache size, but the Opteron 2387 has a 3 MB bigger L3 cache, so in this area, it wins out over the Core i3-7100 2-Core.

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.

The Core i3-7100 2-Core has a 24 Watt lower Maximum TDP than the Opteron 2387, and was created with a 31 nm smaller manufacturing technology. What this means is the Core i3-7100 2-Core will consume significantly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill significantly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

CPU Mini Review

Mini ReviewThe Core i3-7100 2-Core 3.9GHz is a high-end CPU based on Intel's 7th Gen 14nm, Kaby Lake microarchitecture. It offers 2 physical cores (4 logical), clocked at 3.9GHz. It doesn't have an unlocked multiplier, therefore, it can't be overclocked using traditional methods. It has 3MB 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 51W. It is on par with competitor processors. Among its many features, Intel Enhanced Speedstep, HyperThreading and Virtualization are activated. Turbo Boost is not activated. It integrates Intel HD Graphics 630 on board. It has a base frequency of 350MHz which can go up to 1GHz as well as offer DirectX 12 support. This CPU is likely to offer good computational performance but may suffer from performance dips on higher resolutions and demanding applications.Opteron is AMD's x86 server and workstation processor line, and was the first processor to implement the AMD64 instruction set architecture (known generically as x86-64). It was released on April 22, 2003 with the SledgeHammer core (K8) and was intended to compete in the server and workstation markets, particularly in the same segment as the Intel Xeon processor. Processors based on the AMD K10 microarchitecture (codenamed Barcelona) were announced on September 10, 2007 featuring a new quad-core configuration. The most-recently released Opteron CPUs are the 8- and 12-core Socket G34 Opterons, code-named Magny-Cours.
