The CPU is one of the most important components in a computer. It executes the instructions needed to run Windows, software, and games.
But choosing a CPU can quickly become complicated.
Specifications mention cores, threads, GHz, cache, and power. Yet a higher number does not necessarily mean better performance.
In this guide, The Tech Behind has selected five CPUs available for under $300 and compared them using the same methodology.
We take into account:
official specifications from the manufacturers
independent tests from specialized websites
Prices change regularly. The ranking must therefore be considered as a comparison at a given point in time.

1. The 5 Best CPUs Under $300
How to Read This Table
Cores: these are the processing units that perform calculations. Multiple cores allow a CPU to handle several tasks at the same time.
Threads: these are the streams of work that a CPU can process. A 6-core / 12-thread processor can therefore handle multiple tasks simultaneously.
GHz: this indicates the CPU's operating frequency. A higher frequency can improve performance, but it is not enough to compare two CPUs.
Cache: this is a very fast type of memory built into the processor. It stores certain data close to the CPU cores for faster access.
Power: this gives an indication of the CPU's cooling requirements. It does not necessarily correspond to its actual maximum power consumption.
Integrated GPU: some CPUs include a graphics processor that can display an image without requiring a dedicated graphics card.
2. How did we establish our ranking?
Performance (60%):
Performance accounts for the majority of our rating.
To compare them, we rely on benchmarks: tests that measure the performance of a processor in different tasks.
So we don't just rely on the numbers announced by AMD or Intel.
Independent test results may vary depending on software, games, and hardware used. This is why we consider several results before establishing our score.
Performance/price ratio (25%):
A more powerful processor is not necessarily the most interesting.
If two models offer similar performance but one costs much more, its performance/price ratio is less interesting.
Energy efficiency (15%):
Finally, we take into account the energy required to achieve this performance.
Lower consumption can limit the heat produced and simplify cooling.
3. AMD Ryzen 5 9600X: The best balance
The Ryzen 5 9600X has 6 cores and 12 threads.
It can reach 5.4 GHz and has 32 MB of cache. Its announced power is 65 W.
Les Numériques' tests show a processor that performs well in gaming and is particularly interesting in terms of consumption. In particular, the media notes that its test configuration consumption is lower than that of the Core i5-14600K.
Our rating
The Ryzen 5 9600X also has a small integrated graphics part. It allows you to display an image without a dedicated graphics card, but it is not designed for demanding games.

Good to know
The cooler is not included with the processor.
Our analysis
The Ryzen 5 9600X gets the highest rating in our selection thanks to its very good balance of performance, price and energy efficiency.
4. AMD Ryzen 5 7500X3D: A large amount of cache
The Ryzen 5 7500X3D has 6 cores and 12 threads, but its main strength is its large amount of cache.
It features 96 MB of cache, which is particularly high for a processor in this price range.
This additional cache can improve performance in some games by allowing the processor to access more data quickly.

Test of the Ryzen 5 7500X3D — Les Numériques
Test of the Ryzen 5 7500X3D — Clubic
Good to Know
The 7500X3D has a small integrated graphics processor.
The CPU cooler is not included.
Our Analysis
The 7500X3D is particularly interesting if gaming performance is an important part of your usage.
Its large cache allows it to deliver excellent gaming results.
However, its advantage is less significant in some professional applications. This is why we do not automatically give it first place despite its excellent gaming performance.
5. AMD Ryzen 5 7600X: An affordable alternative
The Ryzen 5 7600X has 6 cores and 12 threads, with a maximum frequency of 5.3 GHz and 32 MB of cache.
Its main drawback is its higher power consumption than the Ryzen 5 9600X: its thermal envelope is 105 W.
The tests of the Numériques highlight its good performance in gaming, but also its high power consumption without Eco Mode. The latter makes it possible to significantly reduce consumption while maintaining a large part of the performance.

Good to Know
The Ryzen 5 7600X has an integrated graphics processor.
The CPU cooler is not included.
Our Analysis
The Ryzen 5 7600X remains a capable processor, but its value depends heavily on its price.
If it is significantly cheaper than the Ryzen 5 9600X, it can be an interesting alternative. However, when the two CPUs are similarly priced, the newer model becomes more attractive.
6. Intel Core i5-14600KF: Lots of cores
The Core i5-14600KF has 14 cores and 20 threads.
It can reach 5.3 GHz and features 24 MB of cache.
Its high number of cores and threads allows it to deliver strong performance in applications capable of taking advantage of multiple cores.

Test of the Core i5-14600KF — Les Numériques
Good to Know
The F suffix means that the processor does not have an integrated graphics processor.
A dedicated graphics card is therefore required.
Intel specifies a base processor power of 125 W, with a maximum turbo power of up to 181 W.
Our Analysis
The Core i5-14600KF is one of the most powerful processors in this selection.
Its 14 cores and 20 threads make it particularly well suited to heavily multi-threaded workloads.
However, its higher power consumption and cooling requirements compared with the most efficient Ryzen 9000 processors reduce its final score.
7. Intel Core i5-14400F: The Budget Choice
The Core i5-14400F has 10 cores and 16 threads.
It can reach 4.7 GHz and features 20 MB of cache.
It supports both DDR4 and DDR5, allowing users to choose a platform that fits their budget.

AMD or Intel: Which One Should You Choose?
It is better to compare the models themselves rather than the two brands as a whole. Performance, power consumption and especially price can vary greatly from one processor to another.
Does more cores mean more performance?
No. Performance also depends on the processor architecture, frequency, cache, and software used.
What is a thread?
A thread represents a workflow that the processor can process. In particular, several threads allow you to manage several tasks in parallel.
What is cache?
The cache is a very fast memory built into the processor. It allows you to keep certain data close to the cores so that you can access it quickly.
What is turbo mode?
This is the operation that allows the processor to automatically increase its frequency when temperature and power conditions allow.
What does the "F" stand for at Intel?
The F suffix means that the processor does not have an integrated graphics part. A dedicated graphics card is therefore necessary.
Does the Ryzen 5 7500X3D have graphics?
Yes. It has a small integrated graphics part, mainly intended for basic display.
Conclusion
Choosing a sub-€300 processor isn't just about looking for the highest number of cores or the highest frequency.
You have to compare several elements: performance + price + energy efficiency.
It is this approach that allows us to build our ranking.
