The central processing unit, also referred to as the CPU, is the powerhouse of each single PC. Not like different chips within the system, the CPU is at all times in use and all software program depends on its capability to maneuver information and carry out advanced calculations. How nicely your pc runs purposes and video games is strongly influenced by this piece of silicon, so selecting the best one when it is time for an improve is a crucial choice.
Earlier than you make the leap, although, there are some essential features that it’s best to take into account first, and you will get the knowledge you want by answering 5 vital questions. Here is our information that can assist you by means of these factors, in order that you can select the precise CPU to match your wants and finances.

#1 – Can I hold utilizing my present motherboard?
That is vital as a result of each motherboard helps a particular vary of processors. Should you’re presently utilizing a budget-grade CPU, you could possibly improve to a greater one while not having to alter every other elements within the system.
The easiest way to find out precisely which CPU you may set up in your motherboard is to go to the producer’s web site. Should you’re not sure of the model and mannequin you could have, you may obtain and set up the instrument CPU-Z after which seek the advice of the “Mainboard” tab.
Within the above instance, we are able to see that the system has an Asus TUF Z390-Plus Gaming motherboard. A easy net search rapidly gives hyperlinks to the seller’s product and help pages. On the latter, there’s a record of the CPUs that the board helps.
The very best-spec processor this explicit motherboard can host is an Intel Core i9-9900KS, a 5 GHz 8-core, 16-thread CPU. Nonetheless, this chip was launched in the direction of the top of 2019, and a number of generations of Intel CPUs have been launched since then. So, except you are utilizing a gradual processor, or you’re sure that you do not wish to change the motherboard, putting in an older chip into the system won’t present the efficiency increase you are looking for.
One other facet of the motherboard to contemplate is its chipset – an extra processor that handles all peripheral and storage connections, past these managed by the CPU. Your present motherboard might have a CPU socket that a number of generations of chips can seemingly match into, however the precise CPU compatibility is decided by the chipset.
For instance, Intel’s LGA 1150 socket with a Z87 chipset helps 4th technology Core processors, however not the Fifth-gen ones, although they use the identical socket. Because of this it is essential to test a motherboard’s help web page to see precisely which CPUs it might probably run.
Regardless of providing a far wider vary of help with its sockets, that is additionally true for AMD’s AM4 – the X570 chipset is appropriate with any Ryzen processor, however one thing just like the A320 might require a particular BIOS improve from the motherboard producer to acknowledge Ryzen 3000 and 5000 fashions.

#2 – Can I exploit my present RAM with a brand new motherboard?
For the previous 16 years, there have been solely three generations of RAM for desktop PCs: DDR3, DDR4, and most just lately, DDR5. These varieties are usually not interchangeable, so if you are going to buy a brand new CPU and motherboard, it is vital to test the kind of reminiscence the brand new elements use.
Should you’re planning on getting an AMD processor, your choices are fortunately easy. All fashions that use the AM5 CPU socket (for instance, the Ryzen 7000 sequence) solely help DDR5. If you have already got such a motherboard, you then’ll already be utilizing this kind of RAM, and you will not must improve the motherboard, too.
AMD’s earlier socket, AM4, was launched in 2016 and makes use of DDR4, whatever the motherboard mannequin. So in the event you’re transitioning to the brand new socket, you will want to purchase new RAM. However in the event you’re sticking with AM4 and simply getting a greater CPU, you can proceed utilizing your present reminiscence sticks.
Nonetheless, it is value noting that processors typically perform better with faster RAM. In case your motherboard helps reminiscence with greater speeds, it could be sensible to put money into some new DDR4 sticks. Reminiscence costs fluctuate considerably, and when costs are low, it is wise to accumulate the quickest and largest capability reminiscence kits accessible.
Intel has been utilizing DDR4 since Core Sixth-gen CPUs, launched again in 2015. Its twelfth and Thirteenth-gen processors can deal with both DDR4 and DDR5, however a given motherboard mannequin will solely help one or the opposite; as soon as once more, fastidiously seek the advice of the seller’s product web page to know which one it’s.
If you are going to substitute the RAM, it is best to buy a twin DIMM equipment, as such choices have been examined previous to packaging to make sure that the 2 sticks work completely collectively. You possibly can fill all of a motherboard’s reminiscence slots to max out the capability, however doing so might require you to make use of slower RAM to take care of stability.

- DDR5-6000, 32GB (2 x 16GB) – G.Ability RipJaws S5 Sequence – Amazon
#3 – Do I want a brand new CPU cooler?
All CPU cooling methods are designed to suit a particular socket. For instance, in case your present motherboard has an Intel LGA 1151 socket, any cooler you are utilizing will not match the newest LGA 1700, at the least not with out utilizing a unique help bracket. In case your cooler is a couple of years previous, it is unlikely to have the precise one. The system’s vendor would possibly promote the right bracket, however there isn’t any assure they’ll.
Of even better significance is the quantity of warmth the brand new CPU will generate. For example, as an example your present system makes use of a Ryzen 5 3600 CPU put in in a Gigabyte B450 motherboard. That processor has a TDP (thermal design energy) of 65 W, although it might probably produce extra warmth than this.
Now in the event you have been planning on placing a Ryzen 7 5800X3D processor into this board, it is value noting that this CPU’s TDP is 105 W. That represents a base improve of 62% extra warmth. Should you have been utilizing AMD’s Wraith Stealth cooler, which was bundled with the Ryzen 5 3600, you’ll undoubtedly want a brand new cooler.
With every new technology of Intel’s Core processors, the bottom TDP has considerably elevated, even for the low-end fashions. For instance, the 2019 Core i5-9600 has a TDP of 65 W and will not use far more than that, whereas the newest Core i5-13600 has the identical TDP however a most energy demand of 154 W.
So to summarize, in the event you’re altering to a brand new CPU socket or upgrading to a way more highly effective processor, you will nearly definitely must get a brand new cooler. Utilizing one that may’t switch warmth rapidly sufficient away from the chip will trigger it to achieve its thermal restrict, and the system will then cut back clock speeds to stop injury.
Do not forget that in the event you do get a brand new cooler to go along with a high-end CPU, and it transfers the warmth to the air contained in the PC case, chances are you’ll want to put in extra followers to assist the move of air by means of the chassis. If the cooler can dissipate a considerable quantity of warmth, the air inside will quickly rise in temperature, probably affecting the efficiency of different elements within the system.

#4 – Will my present energy provide unit be ok?
Instantly associated to the earlier query is the subject of the PSU (energy provide unit), because it’s this system that can present the CPU with the ability it requires. Luckily for many individuals, you are unlikely to want a brand new one, however there are two the reason why you would possibly.
Firstly, in the event you’re upgrading from a really previous system and the PSU is from the identical period, you is probably not conscious that trendy motherboards require at the least two energy cables from the provision unit – the normal 24-pin and the more moderen 8-pin.
In case your PSU solely has one further 4-pin cable, you then would possibly have the ability to use it (plugging it into the left half of the connector), nevertheless it will not have the ability to provide sufficient electrical present for a power-hungry top-end CPU. This brings us to the second cause why chances are you’ll must get a brand new PSU.
The largest and strongest CPUs from AMD and Intel can demand a number of energy, particularly the highest Core i9 fashions. For instance, an Intel i9-13900K in some motherboards can draw nearly 200 W greater than an i9-10900K when used beneath heavy hundreds – that is an extra 17 A of present being demanded from the PSU, and older, low-wattage fashions are unlikely to manage.
Not like graphics card producers, CPU distributors do not state minimal PSU necessities for his or her merchandise, nor do they even trace at what the utmost energy demand may probably be. Intel does state figures corresponding to Most Turbo Energy (e.g., for the Core i5-13600 it is 154 W), however it might probably find yourself utilizing greater than this.
Luckily, there are numerous web sites that can estimate the ability provide you will want for a given system (e.g. Newegg, Seasonic, Cooler Master), and as a really tough information, in case your present CPU is lower than 5 years previous and you’ve got a 500 W or greater PSU, then you ought to be wonderful to proceed utilizing that except you are upgrading to one of many top-end chips.
Nonetheless, in case your system is older than that or your PSU affords fewer watts, then getting a brand new unit will seemingly be essential.

- 600 to 850W – Corsair RM850x on Amazon
- 850 to 1000W – Seasonic PRIME 1000 Platinum on Amazon
- Greater than 1000W – EVGA Supernova 1300 P+ on Amazon
#5 – Do I really need a brand new CPU?
This would possibly look like an odd query to have in a information about choosing a new processor, nevertheless it’s a legitimate one to ask your self as a result of the efficiency achieve you will get might not meet your expectations. That is as a result of it relies upon closely on what duties you are giving the chip to crunch by means of.
Sure purposes will take each ounce of CPU energy you may throw at them, and can present positive aspects for each core, clock cycle, or instruction per second that is on supply. Cinebench, Blender, Adobe Premier, or something that entails media creation and modifying are basic instances the place a contemporary, multi-core CPU will severely outperform one thing from 5 years in the past.
Video games, however, are likely to rely extra on the power of the GPU – the exceptions being simulation, technique, and administration titles. These do favor trendy CPUs, as they sport much more cache than older fashions, and AMD’s X3D variants, which have further L3 cache stacked on high of the primary chip, present a major increase in all these video games.
Once we review CPUs, we take a look at them in quite a lot of purposes and video games, and within the case of the latter, it is often at a low decision and with a strong graphics card. That is to make sure that the efficiency figures we see are as depending on the central processor as potential.
Should you solely have a budget-level GPU, then there isn’t any level in pairing it with a high-end CPU, except you intend on upgrading the graphics card comparatively quickly. Contemplating how a lot of a trouble altering the CPU, motherboard, RAM, and cooler could be generally, it would make extra sense to place the cash towards a better GPU.
Past the worlds of gaming and content material creation, even an previous CPU will usually suffice. Or quite, upgrading to more and more trendy processors leads to quickly diminishing returns. A desktop PC with a 4-core, 4 GHz CPU that handles nothing greater than net searching, gentle media consumption, and commonplace workplace duties will profit much more from having ample RAM and quick storage.
That mentioned, there are wonderful processors accessible, and in comparison with fashions from 8 to 10 years in the past, they’re immensely highly effective and extra environment friendly. Relying on what you are going to use them for, upgrading to one of many newest choices will serve you nicely for a few years to return.
