In terms of overall gaming performance, the Intel Pentium Gold G5400 2-Core 3.7GHz is noticeably better than the AMD APU A12-9800E 4-Core 3.1GHz 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 G5400 was released less than a year after the APU A12-9800E 4-Core, and so they are likely to have similar levels of support, and similarly optimized performance 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 APU A12-9800E 4-Core has 2 more cores than the Pentium Gold G5400. With 4 cores, the APU A12-9800E 4-Core is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

Both the AMD APU A12-9800E 4-Core 3.1GHz and the Intel Pentium Gold G5400 2-Core 3.7GHz have the same number of threads. The APU A12-9800E 4-Core has one thread per physical core, whereas the Pentium Gold G5400 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 APU A12-9800E 4-Core and Pentium Gold G5400 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 G5400 has a 0.6 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 enough that it possibly indicates the superiority of the APU A12-9800E 4-Core.

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 APU A12-9800E 4-Core has a 1536 KB bigger L2 cache than the Pentium Gold G5400, and although the APU A12-9800E 4-Core does not appear to have an L3 cache, its larger L2 cache means that it wins out 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 APU A12-9800E 4-Core has a 16 Watt lower Maximum TDP than the Pentium Gold G5400. However, the Pentium Gold G5400 was created with a 14 nm smaller manufacturing technology. Overall, by taking both into account, the Pentium Gold G5400 is likely the CPU with the lower heat production and power requirements, by a small amount.

The Pentium Gold G5400 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 APU A12-9800E 4-Core, 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 AMD APU A12-9800E 4-Core 3.1GHz is a budget APU based on AMD's 28nm Excavator microarchitecture. It offers 4 physical cores (4 logical) initially clocked at 3.1GHz, rising to 3.8GHz in boost mode. It has an unlocked multiplier and therefore can overclocked using traditional methods. It has 2MB of L2 Cache. This processor also supports DDR4 based RAMs with maximum memory support of 64GB. It has a maximum Thermal Power Design of 35W, making it a low-end, power-efficient CPU. Among its many features are Cool n Quiet, CoolCore Technology, Extended Frequency Range (XFX), Pure Power and Precision Boost are enabled. The APU A12-9800E 4-Core 3.1GHz features integrated Radeon R7 3rd Gen GCN graphics with 512 Shaders and a maximum clock speed of 900MHz. This is a low-end graphics chip that will struggle to run any modern game at 720p.The Pentium Gold G5400 2-Core 3.7GHz is a budget processor based on the 14nm Cofee Lake architecture. It offers 2 Physical Cores (4 Logical), clocked at 3.7GHz 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 (Kaby Lake), with 24 Execution Units, initially clocked at 350MHz and that go up to 1050MHz, 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 51W. Intel's Pentium Gold G5400 2-Core 3.7GHz offers average to good performance and is classified in the low to middle-class range of processors. This means it will become a bottleneck in some demanding applications, although gaming performance will be largely fine.
