If you're getting the itch to upgrade your CPU, like many PC enthusiasts, you've no doubt been watching the releases of Intel's Arrow Lake and AMD's Ryzen 9000 series very closely. So you're probably already aware that both manufacturers have gone on a diet this year, with a push for more efficient CPUs instead of the generational performance boosts of prior releases. That means this year's best CPUs from Intel and from AMD might actually not be the best CPUs for you and the type of tasks you perform. The nuances of the conversation this year aren't just around new features or percentage performance increases, and many users can likely pause their upgrade for another few months at least.

Your current CPU might be enough already

Not everyone needs to upgrade to the bleeding edge

Ever since personal computers became affordable, we've been conditioned to this never-ending cycle of upgrades and refreshes. It's not the only industry that tries to get us to upgrade every year to new shiny objects, but because of the number of components inside our computers, it often feels overwhelming. The good news is that for most users, the cycle can be broken. With games getting ever more reliant on graphics card power, many, if not most, CPUs from the last five years or so with six cores or more are powerful enough to achieve respectable FPS scores in games.

It's also important to match your CPU to your GPU so you don't accidentally bottleneck your system. If your CPU usage is still relatively low on Task Manager while you're gaming or performing heavy productivity tasks, it's not your processor that's making your computer feel slow. Also, if your GPU utilization score is 90% or more, the task you're doing is GPU-limited, and a CPU upgrade wouldn't help much anyway. That equation changes once GPU utilization drops below 70% or so, but even then, it might just mean that the game or app you're using isn't optimized to use your system fully. There's no one-fits-all set of rules for when to upgrade, but here are some things to consider before you pull the trigger on that new CPU:

• CPUs like the AMD Ryzen 7 5800X3D or AMD Ryzen 7 7800X3D, which have more L3 cache, are faster at gaming tasks
• RAM speed has little effect on gaming performance, so you might not need to upgrade that
• Most gamers don't need more than six cores for good performance
• Newer CPU architectures are usually better at gaming, but you don't have to upgrade every generation. When doing so, if your CPU is two or more generations back, you'll likely get more of a boost to performance. That's currently Intel 12th generation and AMD Ryzen 3000 or 5000

If none of these apply or if you're happy with your CPU, you can look at other system components to upgrade instead, like getting a faster NVMe SSD, which will likely make your PC feel faster in everything you do on it.

This year is a soft reset

Efficiency is key in this generation but it's better to wait

This year, both AMD and Intel changed the focus of their technological upgrades with a renewed push for efficiency. AMD's Ryzen 5 9600X and Ryzen 7 9700X are some of the most efficient CPUs we've tested, and while they haven't exactly been received well by the vocal minority of enthusiasts, they are fantastic value and sip power while performing at a high level. With a 65W TDP (and optional 105W unlocked mode), they're easy to cool, have plenty of cores and threads, and with the AM5 socket having a few years of life yet, give a viable upgrade plan. But they're not that huge of a jump in performance from recent CPU generations, so unless you're running something from the mid-2010s, it's not a necessary upgrade.

Intel's 14th generation was performant but came at a cost of thermal efficiency, in that it had none. Temperatures regularly climbed to 100C and stayed there only by thermal throttling so the CPU wouldn't be damaged. With Core Ultra (Gen 2), the total package draw can reach 244W, but it runs cooler than any Intel CPU we've tested from the last three generations, including some Intel Core i5 processors that are supposed to use less power. It's an impressive achievement when we're used to Intel CPUs running hot, but that comes at a cost to performance. If you've got a fairly performant CPU from the last few years, there's little here to tempt you to upgrade.

And you might need a new motherboard

Depending on how old your current CPU is, which CPU you want to upgrade to, and which motherboard you have, you might need to do a full platform upgrade. That means CPU, motherboard, and RAM, so the costs add up pretty quickly. Intel usually changes its platform support every other generation, but this year is a full refresh, so you'll need a new motherboard even if you own a 14th gen CPU. If your Intel CPU is older than the 12th gen, you might also need new RAM. AMD switched to the AM5 socket a couple of years back with Ryzen 7000, so if you want to upgrade to Ryzen 7000 or 9000, you need both an AM5 motherboard and DDR5 RAM. That increased cost makes the value proposition hard this year, and it really depends on if your particular productivity or gaming needs will benefit from the upgrade.

You might not feel the need to upgrade your CPU this year, and that's okay

With the CPU market going through a small correction of values and focus, it's perfectly fine to sit this generation out. As with any major shift in technology, there will be issues in the hardware and software to iron out, and the performance boost over recent processors might not be that much due to the push for efficiency. That's the picture for anyone who is thinking of upgrading, but it's slightly different if you're buying a whole new PC. For those building a new PC, absolutely go for the current generation, which is AMD's Ryzen 9000 series or Intel's Core Ultra (Gen 2) aka Arrow Lake. Since you're starting from scratch, you don't have the frame of reference from upgrading, and you should always try to buy the latest generation so it will last you longer.
