In terms of overall gaming performance, the AMD Opteron 6276 is massively better than the Intel Pentium Gold G5420T 2-Core 3.2GHz 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 Pentium Gold G5420T was released over three years more recently than the Opteron 6276, and so the Pentium Gold G5420T is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Opteron 6276 when running the latest games.

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 Opteron 6276 has 14 more cores than the Pentium Gold G5420T. With 16 cores, the Opteron 6276 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 Pentium Gold G5420T and Opteron 6276 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 Pentium Gold G5420T has a 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 6276 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 6276 has a 488 KB bigger L2 cache than the Pentium Gold G5420T, which means that it, at worst, wins out in this area, and at best, will provide superior gaming performance and will work much better with high-end graphics cards.

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 Pentium Gold G5420T has a 80 Watt lower Maximum TDP than the Opteron 6276, and was created with a 18 nm smaller manufacturing technology. What this means is the Pentium Gold G5420T 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 Pentium Gold G5420T 2-Core 3.2GHz is a budget processor based on the 14nm Coffee Lake architecture. It offers 2 Physical Cores (4 Logical) clocked at 3.2GHz, and 4MB of L3 Cache. Among its many features, Hyperthreading, Virtualization, and Enhanced SpeedStep are activated. The processor integrates Graphics called Intel UHD Graphics 610 (Coffee Lake), with 12 Execution Units, initially clocked at 300MHz and that goes up to 1100MHz in Turbo Mode which shares the L2 Cache and system RAM with the processor. It will struggle to run the latest AAA games at playable frame rates. Both the processor and integrated graphics have a rated board TDP of 35W. Intel's Pentium Gold G5420T 2-Core 3.2GHz offers good budget performance and is classified in the low-end range of processors. This means it will become a bottleneck in some demanding applications, particularly modern games which rely on multiple cores.Opteron Hexadeca Core 6274 is a 16-Core Server CPU part of the Opteron 6200 Series released by AMD in 2011/2012.
Each Core is clocked at 2.2 and features one thread, making a total of 16.
Obviously not designed for gaming, due to its tremendous price, it will deliver great performance for those crazy enough to use for extreme gaming performance.
