Importance of Single-Core Performance for Gamers 🎮
Key findings:
Single-core performance refers to the maximum capability of a single core in a CPU 🖥️.
Most games don't efficiently take advantage of multiple CPU cores due to the complexity of splitting workloads ⚙️.
While single-core performance is critical for gaming PCs, game engines are improving to utilize more cores effectively 🚀.
Nowadays, both gaming consoles and PCs feature multi-core CPUs, but there’s still a lot of talk about “single-core performance” and its impact on running a game 🕹️. If you’ve been wondering what this means or why it’s so important, I’ll explain it to you in a simple and clear way.
What is single-core performance? 🤔💡
Modern CPUs come with multiple "cores." A core is basically a complete, stand-alone processor. So a modern CPU actually has multiple CPUs inside it. When we talk about single core performance, we are referring to the best possible performance that can be obtained from a core of that CPU operating at its maximum potential. 🏎️💨
He software generates "threads", and each of these is processed by an independent core. Some processors can even work on several threads at the same time, thanks to technologies like the hyperthreadingFor example, if you're rendering a video project in something like Adobe Premiere, the rendering workload can be split across multiple threads. 🎥✨
Si tenés una CPU que puede procesar 12 subprocesos, obtendrás esa cantidad. Si tu CPU puede manejar 100 subprocesos, obtendrás esa cantidad. Esto asegura que la CPU se utilice al máximo y se obtenga el mayor performance possible. 🚀💻
However, if all CPU cores are active, their individual performance is not as fast as they could be on their ownThis is because running all cores under load increases heat and power usage. 🔥⚡
So the cores run at lower clock speeds to compensate. Still, you get a lot more performance than just running everything on a single core at a higher clock speed, so the trade-off is worth it. ⚖️👌
🎮 Did you know that most games don't take full advantage of all the cores in your processor? 🤔
The thing is, not all software can be divided so neatly into multiple threads. With jobs like offline graphics rendering or video conversion, it's easy to divide the work for each CPU core. However, games don't have this kind of workload. 🎮
Un juego puede tener un hilo para la física, otro para la IA, uno para ejecutar una simulación específica en el mundo abierto, otro para ayudar a la GPU con el trazado de rayos, etc. Los juegos han sido notoriamente difíciles de «enhebrar» de tal manera que puedan utilizar muchos núcleos. 🧩 Es por eso que las Gaming PC have been behind the main race for quite some time.
If you just want to play video games, you don't need a lot of cores. Nowadays, the sweet spot seems to be six to eight, which makes sense since all the consoles top phones have eight-core CPUs and that's what the developers are coding. 🎮💻
🎮 The main thread is the common denominator 🧵
So what's the problem with single-core performance? 🤔 In most games, there is one core thread that acts as the backbone of the game. Execute logic and processes main thread of the game, and is responsible for distributing work to other subordinate threads. In other words, there is a thread that the other threads in the game have to wait for before they can do their work. 🕒
Therefore, the fastest game performance cannot exceed the speed at which this main thread can run. When we say that a game is “CPU limited” or that there is a “CPU bottleneck”, it is usually because this thread is running at a very high speed. software main is limited by the highest possible performance on a single thread of a given CPU. 🚀
Some CPUs are designed for threads
🎮 Do you think that buying the most expensive CPU is the best option for your games? 🤔 That's not always the case! Even if your budget allows you to choose the most expensive one, it doesn't mean that it's the best for gaming. CPUs with many cores usually have lower performance per core compared to cheaper models in the same line. 🤑
These CPUs are designed for software which can distribute the work evenly across all cores. In these cases, they do outperform the other options. But be careful, because this also means that each individual core does not reach the same levels of performance. 🚀
Now, this isn't always the case. If two CPUs have the same boost clock frequency on a single core, even with different core counts, the performance per core should be similar. 💡
So for a PC that you're going to use primarily for games, you don't need a 24-core CPU. An eight- or twelve-core CPU, but with high performance and speed, is more than enough. 🖥️👌
Things are changing for games
🔥 Aunque el rendimiento de un solo núcleo sigue siendo clave para los videojuegos, ¡las cosas están cambiando! 🎮 Los motores de video games They are now taking advantage of more cores, and developers are finding clever ways to distribute the workload across the available CPU cores. 📈
For example, Bethesda with his Doom Eternal has shown that does not depend on a single thread of work central that can stop everything. 🚀 Have a large amount of cache CPU is becoming another crucial factor for gaming CPUs. This is clearly seen in the successful 3D V-cache gaming CPUs from AMD. 🏆
At this point, I wouldn't recommend buying a CPU with more than eight cores if your main goal is to play 🎮. However, in the future, we're likely to see games that can take advantage of more cores 🖥️. This will allow the main thread to be split into more threads, preventing a single core from being overloaded to the limit 🚀.
