In terms of overall gaming performance, the Intel Core i3-9300 4-Core 3.7GHz is massively better than the AMD Opteron 2378 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 Core i3-9300 4-Core was released over three years more recently than the Opteron 2378, and so the Core i3-9300 4-Core is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Opteron 2378 when running the latest games.

The Core i3-9300 4-Core and the Opteron 2378 both have 4 cores, which is not likely to be a limiting factor for gaming.

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 i3-9300 4-Core and Opteron 2378 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 i3-9300 4-Core has a 1.3 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 Opteron 2378 has a 1024 KB bigger L2 cache than the Core i3-9300 4-Core, but on the other hand, it is the Core i3-9300 4-Core that has a 8186 MB bigger L3 cache than the Opteron 2378. In this case, the L2 size is probably what counts, so the Opteron 2378 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.

The Core i3-9300 4-Core has a 13 Watt lower Maximum TDP than the Opteron 2378, and was created with a 31 nm smaller manufacturing technology. What this means is the Core i3-9300 4-Core will consume slightly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill slightly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

The Core i3-9300 4-Core has an on-board GPU, which means that it will be capable of running basic graphics applications (i.e., games) without the need for a dedicated graphics card. The Opteron 2378, however, does not, and you will probably have to look for a dedicated card if you wish to use it at all.

On-board GPUs tend to be fairly awful in comparison to dedicated cards from the likes of AMD or Nvidia, but as they are built into the CPU, they also tend to be cheaper and require far less power to run (this makes them a good choice for laptops). We would recommend a dedicated card for running the latest games, but integrated GPUs are improving all the time and casual gamers may find less recent games perform perfectly acceptably.

CPU Mini Review

Mini ReviewThe Core i3-9300 4-Core 3.7GHz is a low-end desktop CPU based on a refinement of the 14nm++ Coffee Lake microarchitecture. It offers 4 physical cores (4 logical), initially clocked at 3.7GHz, which may go up to 4.3GHz using 4 cores with Turbo Boost. The i3-9300 has 8MB of L3 Cache. This chip supports up to 64GB 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. It does not feature an unlocked multiplier and therefore cannot be overclocked using traditional methods. This Core i3-9300 CPU offers average gaming performance in 2019 and should not be a major bottleneck in any modern gaming PC. It will be able to play most modern games at 60fps on High graphics performance at any supported resolution without being a hindrance to the accompanying GPU. However, performance may become bottlenecked if playing at 144Hz and 1080p or lower screen resolution.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.
