Generally, emulation mostly runs off the CPU, with the GPU allowing for higher resolutions, anti-aliasing, and so on. If your CPU isn't fast enough, you probably won't be able to emulate a system at its full speed. At the very least, a Core i5-2500K or better is recommended for high-end emulation (e.g. [[PlayStation 2|PS2]], [[Wii]]). This page will detail specific information for specific systems, provided that the above is not a viable option.

Just because a CPU has a high clock speed (Pentium 4 HT 672 3.8 GHz), doesn't mean that it is powerful.<ref>http://www.computer-hardware-explained.com/megahertz-myth.html</ref> For example, a Celeron D 365 overclocked to 8 GHz is light-years less powerful than a Xeon X5698 running at 4.5 GHz. Newer CPUs tend to fare better, though the particular architecture does matter determining its real-world performance. A common misconception is that a higher CPU clock speed guarantees improved emulation performance, which doesn't always apply. Although clock speed is one of the main factors for good CPU performance, it is not always the determining factor. For example, a Core 2 Duo E6600 @ 2.4GHz CPU will mostly outperform a Pentium D 940 @ 3.2GHz CPU. Even though the Pentium D is clocked higher, the Core 2 Duo is still faster due to the reduced amount of pipeline stages and a wider execution unit. This improves the instructions-per-clock cycle performance it can output, which means better performance at a lower clock speed.

===Overclocking===

Not every CPU can be overclocked, nor does every motherboard/BIOS support it. An advantage of the Intel K series is that they are unlocked and can easily be overclocked. Also, certain Intel processors such as their Pentium 20th Anniversary CPU are sold unlocked for a cheaper price than K-series chips, and while they may lack features like hyperthreading, they're capable enough especially for those who would like to overclock on a budget. Keep in mind that budget motherboards e.g. certain Haswell H and B-series boards from ECS and ASUS only have options for setting the processor's multiplier and not voltages. Also, Intel may block overclocking on non-Z series boards in future microcode/BIOS updates. So if it can't play a game currently then you can, in many cases, overclock it until it is playable. Laptop CPUs often cannot be overclocked due to BIOS limitations. Extreme or incorrectly-done overclocking can cause instability and hardware damage. If the emulator starts having problems try again without overclocking.
+
Not all CPUs can be overclocked, and the motherboard's BIOS must be additionally capable of supporting overclocking. The CPUs in particular that can be overclocked are the usually the ones that are labeled: OverDrive, FX, Extreme Edition, Black Edition, K, and X. Also, certain engineering or qualification sample CPUs that AMD or Intel has manufacturered may also be overclockable, since they were used for testing purposes and were not meant for sale. If you are not sure what kind of a CPU you have, check if it has these overclocking labels. For Intel CPUs, their overclocking labels are OverDrive, Extreme Edition, K, and X. And for AMD CPUs, their overclocking labels are FX, Black Edition, and X.
 +
 
 +
Although special processors such as the Pentium G3258 are overclockable; you must be running the CPU on a motherboard that supports overclocking. The motherboards that tend to support overclocking features, comes with a chipset that also supports overclocking, which is required for the CPU to be overclockable. However, this only applies to the newer motherboards, not the older motherboards as they tend to vary from being overclockable to not overclockable. For Intel, the overclockable chipsets' name starts with an X or a Z. The other chipsets that were not mentioned, are not overclockable (B, C, H, and Q). For AMD, the overclockable chipsets' name starts with an X or a B. The other chipsets that were not mentioned, are not overclockable (A).
 +
 
 +
For older desktop motherboards with older chipsets, there might be overclocking available in the form of a front-side bus setting. Use that setting with caution however, as the front-side bus clock speed gets raised, so does the rest of the other components on the motherboard (which causes instability, data loss, etc). Unless the motherboard has a PCI/AGP lock, it is advised not to use the front-side bus setting to overclock the CPU. In further depth, there is safer setting that can be used to overclock without suffering from instability. Called the 'CPU BSEL Select' or similar, it was intended to manually select the proper front-side bus clock speed of the CPU. Though, by this, it allows us to exploit that feature and use it to overclock while staying within the factory specifications of the motherboard. This does not affect the rest of the other components on the motherboard, as the front-side bus is not overclocked and is only following the rated speeds it can achieve. Therefore, it is safer than the dangerous front-side bus setting. Also, be aware that once the CPU has hit a certain clock speed, it can no longer overclock due to voltage issues. The reasoning behind this is because of how higher clock speeds require more voltage, and these non-overclockable motherboards have a high chance of not having the ability to modify the input voltage to the CPU.
  
−
For older desktop motherboards, there is a chance of it supporting overclocking by increasing the FSB clock speed. This might or might not apply to many old motherboards. Generally, they should be capable of changing their FSB clock speed with a small edit in the BIOS. The issue is that those that support changing the FSB clock speed, might not be capable of changing the processor's supplied voltage without doing wire wrap modifications or similar to the socket. Which makes it very difficult for an overclock to be stable. There must also be a PCI/AGP lock to prevent the FSB from increasing other clock speeds of different components on the motherboard, as this removes the chance of killing or destroying other crucial components. You can still overclock without it, but try not to cross the 40 MHz mark on the PCI bus. Also, increasing the processor's supplied voltage isn't exactly necessary for certain processors that are well-known to handle substantial increases in clock speeds. Another factor is the motherboard, as it depends on its VRMs to supply voltage. Thus due to this, low-end motherboards with lower-grade VRMs won't be as powerful to supply sufficient voltage for the processor be stable.
+
However, if there is no 'CPU BSEL Select', proceed with the front-side bus setting with caution. As a safety precaution, do whatever it takes to not allow the PCI bus' clock speed to reach above 40 MHz. As anything higher than the 40 MHz mark will have a very high chance of inducing instability and possible data loss, or worse. This is why the front-side bus setting is only recommended for motherboards that are equipped with a PCI/AGP lock, since they prevent the other components on the motherboard from being overclocked. Also, be aware that your motherboard can only supply a limited amount of current before it hits its limits. This is due to the voltage regulator modules not being rated to supply a large amount of current to keep the CPU and the rest of the other components stable, which is common for motherboards that are not meant for overclocking. The CPU's potential overclock may also be limited by the power supply unit, so a better power supply unit with better efficiency and wattage rating may be required.
  
 
For certain laptop CPUs, some of them can be overclocked. A good way to acknowledge that you have an overclockable CPU is to check if it has an "Extreme" label on its name for Intel processors, or a "Black Edition" label on its name for AMD processors. As most laptops don't allow overclocking through the BIOS, third-party applications such as ThrottleStop must be used to overclock these processors instead. However, if your laptop does not have enough thermal headroom for overclocking, it is suggested that you don't overclock. Otherwise, you risk a chance of purposely throttling the CPU's speed and getting slower results instead. This is due to the built-in temperature protection that exists in most laptop CPUs, which generally does not allow itself to exceed 100 degrees celsius.

Generally, emulation mostly runs off the CPU. And the GPU allowing for higher resolutions, anti-aliasing, and so on. If your CPU isn't fast enough, you will most likely be not able to emulate a system at full speed. At the very least, a Core i5-2500K or a Ryzen 3 1300X or better is recommended for high-end emulation (e.g. PS2, Wii). This page will detail specific information for specific systems, provided that the above is not a viable option.

CPU

Megahertz Myth

Just because a CPU has a high clock speed (Pentium 4 HT 672 @ 3.8 GHz), doesn't necessarily mean that it is powerful.[1] For example, a Celeron D 365 @ 3.6 GHz is less powerful compared to a Celeron E1600 @ 2.4 GHz. Most newer CPUs tend to fare better, though the particular architecture does matter determining its real-world performance. A common misconception is that a higher CPU clock speed guarantees improved emulation performance, which doesn't always apply. Although clock speed is one of the main factors for good CPU performance, it is not always the determining factor. For example, a Core 2 Duo E6600 @ 2.4GHz will always outperform a Pentium D 940 @ 3.2GHz. Even though the Pentium D is clocked higher, the Core 2 Duo is still faster due to the reduced amount of pipeline stages and a wider execution unit. This improves the instructions-per-clock cycle performance it can output, which means better performance at a lower clock speed.

This comparison only points to AMD's Bulldozer microarchitecture versus Intel's Ivy Bridge microarchitecture, not currently: This is also true of many modern Intel vs AMD CPUs[2][3][4][5][6][7], as the high-end Intel CPUs are more efficient than the high-end AMD CPUs. Main reason for that is because Intel CPUs have higher performing floating-point units,[8][9] far greater cache/memory bandwidth/lower latency[10][11].

AMD vs. Intel

As of Ryzen (Summit Ridge), AMD CPUs have similar single-threaded performance when compared to Intel CPUs, though still not exactly close to an equivalent Intel CPU of the same era. However, both choices are good for emulation.

Desktop vs. Laptop

Laptop CPUs are typically much weaker than their desktop variants due to being clocked lower, for battery conservation and heat management reasons. They may also have fewer cores than desktop CPUs with similar naming schemes, which may confuse you. Therefore, it is suggested to research on a mobile CPU's performance before purchasing a laptop that comes with the said CPU.

More Cores and Threads

Emulators generally only utilize 2 cores, or with hacks, sometimes 3 or 4 cores. Thus, owning a 6 or an 8-core CPU, or one equipped with Hyper-Threading/Simultaneous-MultiThreading, won't benefit you anymore than having a similar quad-core CPU. Although, certain exceptions such as newer system emulators (e.g: RPCS3) can utilize more cores by emulating the system's thread scheduler, which allows it to use as many cores as a game makes threads.

Still, the general recommendation is to go for a higher-clocked 2/4/6-core CPU, as most emulators currently can not fully utilize 6 cores or more. Examples include the Core i3-7350K, Core i7-7740X, and the Core i7-8086K.

Overclocking

Not all CPUs can be overclocked, and the motherboard's BIOS must be additionally capable of supporting overclocking. The CPUs in particular that can be overclocked are the usually the ones that are labeled: OverDrive, FX, Extreme Edition, Black Edition, K, and X. Also, certain engineering or qualification sample CPUs that AMD or Intel has manufacturered may also be overclockable, since they were used for testing purposes and were not meant for sale. If you are not sure what kind of a CPU you have, check if it has these overclocking labels. For Intel CPUs, their overclocking labels are OverDrive, Extreme Edition, K, and X. And for AMD CPUs, their overclocking labels are FX, Black Edition, and X.

Although special processors such as the Pentium G3258 are overclockable; you must be running the CPU on a motherboard that supports overclocking. The motherboards that tend to support overclocking features, comes with a chipset that also supports overclocking, which is required for the CPU to be overclockable. However, this only applies to the newer motherboards, not the older motherboards as they tend to vary from being overclockable to not overclockable. For Intel, the overclockable chipsets' name starts with an X or a Z. The other chipsets that were not mentioned, are not overclockable (B, C, H, and Q). For AMD, the overclockable chipsets' name starts with an X or a B. The other chipsets that were not mentioned, are not overclockable (A).

For older desktop motherboards with older chipsets, there might be overclocking available in the form of a front-side bus setting. Use that setting with caution however, as the front-side bus clock speed gets raised, so does the rest of the other components on the motherboard (which causes instability, data loss, etc). Unless the motherboard has a PCI/AGP lock, it is advised not to use the front-side bus setting to overclock the CPU. In further depth, there is safer setting that can be used to overclock without suffering from instability.

As a safety precaution, do whatever it takes to not allow the PCI bus' clock speed to reach above 40 MHz. As anything higher than the 40 MHz mark will have a very high chance of inducing instability and possible data loss, or worse. This is why the front-side bus setting is only recommended for motherboards that are equipped with a PCI/AGP lock, since they prevent the other components on the motherboard from being overclocked. Also, be aware that your motherboard can only supply a limited amount of current before it hits its limits. This is due to the voltage regulator modules not being rated to supply a large amount of current to keep the CPU and the rest of the other components stable, which is common for motherboards that are not meant for overclocking. The CPU's potential overclock may also be limited by the power supply unit, so a better power supply unit with better efficiency and wattage rating may be required.

For certain laptop CPUs, some of them can be overclocked. A good way to acknowledge that you have an overclockable CPU is to check if it has an "Extreme" label on its name for Intel processors, or a "Black Edition" label on its name for AMD processors. As most laptops don't allow overclocking through the BIOS, third-party applications such as ThrottleStop must be used to overclock these processors instead. However, if your laptop does not have enough thermal headroom for overclocking, it is suggested that you don't overclock. Otherwise, you risk a chance of purposely throttling the CPU's speed and getting slower results instead. This is due to the built-in temperature protection that exists in most laptop CPUs, which generally does not allow itself to exceed 100 degrees celsius.

If your processor is unfortunately not an Extreme or a Black Edition, don't worry. There is an old way of increasing the FSB clock speed through the PLL. The PLL or otherwise known as the Phase-Locked-Loop is a chip that usually controls the FSB clock speed signal, internally for desktops and laptops alike. In this desperate case, we can use ClockGen or CPUCool or SetFSB to control the PLL for increased speeds. A cautionary advice to take note of, is that laptops mostly do not come with a PCI/AGP lock. This means that you will still face the potential data corruption that may occur at higher FSB clock speeds, so the desktop's 40MHz PCI do-not-cross-line mark still applies in this case. However, this only applies if your laptop's PLL is supported by one of these programs mentioned. You will be unfortunately, out of luck if all of these programs do not support your laptop's PLL.

GPU

GPUs are basically just hundreds of under-powered CPUs on the same die, or better described as a massively parallel CPU with a core count that far exceeds most traditional multi-core CPUs.

The thing is, with 3D graphics, you can split the work up into hundreds of different parts and give each piece to a different core on the GPU to work on. Since it doesn't matter which order the pixels are rendered in, as long as they all get rendered for the same frame before moving on to the next frame.

File compression/extraction and bitcoin mining are also good examples of programs that can make use of parallel processing. However, most programs can not do this. Dwarf Fortress, for example, can't make use of a graphics card. Because every calculation it does is dependent on the one did before it. That obviously doesn't work if you try and do them all at the same time.

Pretty much any emulator is the same; it does not know what comes next until it has done what preceded it. It has to run off a single thread. It still needs some form of graphical output to output the final rendered 2D screen alone. This can be done via a GPU to put the 3D graphics on the screen, but any system capable of being emulated shouldn't be too taxing. This is called "Hardware Rendering". Alternatively, all of the graphics processing can be done on the CPU and will be more predictable/consistent for it, but that is also costly. This is called "Software Rendering".

Most 3D emulators have hardware and software renderers. Software renderers use more CPU power, which may mostly be slower. They may also run on their own threads separate from other emulator parts, which would likely reduce the performance loss, but the CPU must still be fast enough in the first place.
