4 core vs 6 core CPU: How they work and Performance

If you need to build a new computer or laptop, one of the biggest decisions you will have to make is whether to go with a 4 core or 6 core CPU. Here is a look into how many cores you need, what a 4 core and 6 core processor actually is, and how many cores can be too many. Let’s have a look.

How do CPU Cores work?

CPU stands for central processing unit, and it is used for computing and processing. It has a central processing unit (CPU) that controls other components such as memory, disk drives, etc.

CPU cores are divided into two types – processing units and cache memories. Processing units compute logical operations like Addition, Subtraction, Multiplication, and Division. Cache memories store recently-used data to be used immediately without accessing the main memory. Each core has its dedicated processing unit and cache memories. Each cache memory is divided into two banks or lines.

These cores are physically located in different chip areas or on additional chips. They all have access to the same memory space. Each core has its instruction decoding unit. When the computer executes an instruction, it travels from the instruction decoder to the execution stage, where it is executed by a functional unit, typically either a micro-operation (uop) or macro-operation (macro op), depending on the instruction decoder on the type of instruction.

Each core has an associated processor (e.g., Intel Pentium), a level one cache (i.e., L1 cache), a level two cache (i.e., L2 cache), and memory that contains instructions and data. The processors use a processor unit to execute instructions stored in memory, and the caches have specialized hardware used to access instructions. When executing instructions, these processors will read instructions from memory and transfer data to and from memory on their own. A processor can perform many operations simultaneously, such as processing multiple instructions in parallel.

4-Core vs. 6-Core for Gaming?

This is a very difficult question because it depends on how many cores you have. If you only have one or two, the more cores you have, the better because games can be very processor-heavy. On the other hand, if you have lots of cores, they will likely run parallel, and all be used. In this case, it makes sense to get a dual- or quad-core system because 2 or 4 CPUs are always ready to run simultaneously, so the system will almost always be using its maximum performance.

If you want to play video games on a modern computer, most people would recommend getting a system with at least 4-cores (4 CPUs or processing units). In recent years more expensive processors are 6-core. However, it is very rare to find a computer today with more than 6-cores. So why not go for a 4-core system as it is much cheaper and does the job just as well? There are several advantages to having at least 4-cores on your gaming machine, including more memory (RAM), graphics power, and a more stable frame rate.

For Instance, AMD Ryzen 5 2400G has four cores, while i7 7700HQ has six cores.

4-Core vs. 6-Core for Office Work?

In the case of the 4-core processor, this is a question of performance vs. energy. On the one hand, you have a very high-performance level, but the downside is that the more cores you use, the more power consumption increases. For most business tasks, six or eight cores are the sweet spot to provide maximum performance with minimum consumption.

Moreover, You can’t run a 4-core PC on a 2-core motherboard; even if you use an external PCI 3.0 card, it will not work. But a 6-core motherboard with a 6-core processor will work fine. 

There is no clear reason. However, it can be said that most office jobs can take advantage of a 4-core CPU because most of the CPU processing work is done in the CPU. On the other hand, if we have a 6-core CPU, we can use all CPU cores, but there is a tradeoff between performance and power consumption.

For best results with 6-core (dual-core or quad-core) or more processors, use an Intel A 7500 or 7200 ULTRA series motherboard. You will see a substantial performance increase and lower heat levels with more than six cores. However, a single-core processor is enough for most users, such as students, home users, and hobbyists who simply want to play games.

4-Core vs. 6-Core for Image Editing and Graphic Designing?

There is no big difference in the performance between both. The main difference is that 4-core has a lower clock speed than 6-core. 4-core can run at a higher clock speed, but this will mean that it will consume more power. Also, it takes some time to wake up the processor if you need to use it quickly (i.e., you can’t use it in sleep mode).

The main reason for four cores is that most modern graphic editors are built using a 4 core architecture. For those who do not know, 4 cores are processors that do the work of one CPU core at the same clock speed. 4 cores allow you to run multiple programs on your computer simultaneously and give you more power and multitasking ability. However, it’s best to have more than 4 cores for graphics editing because the image file size will expand dramatically if you use more than 4 cores. As a result, Photoshop uses less than 4 cores when working on large files like A4 and A3 images but usually works with at least 8 cores to maximize speed. 

Also, when it comes to image editing and graphic designing, many graphic elements like text, lines, shapes, and other objects need to be created. And then, to do that, a person should be using a 4-core CPU instead of a 6-core CPU. If you have a 6-core CPU, some of the cores may be idle. But if a 4-core CPU is used, all of its cores can be active, so no core is idle. This will make your computer run faster than a 6-core CPU.

4-Core vs. 6-Core for Video Editing?

 There is not much difference between 4 cores and 6 cores unless you do very fast editing with video. For example, we would do real-time video editing on the 6-core system.

It depends on what software you use to edit your videos. A good editor will use only one CPU core, while a bad one may use all 4 cores (4-core CPU). The more cores in a processor, the more simultaneous processes you can run.

4-core is for editing video, while 6-core is for editing photos. If you edit a video on a computer with a 4-core processor, it will use the full speed of the processor, i.e., 2 GHz. However, if you edit a video on a computer with a 6-core processor, it will not use the full speed of the processor, i.e., 2.5 GHz. You need to choose the right processor for your work and budget.

 4 cores are a lot better than 6 cores. You’ll probably want to do some heavy lifting with a video editor, such as compressing video frames or applying filters on the fly. Doing these tasks will require more processing power. So 6 cores will give you a headache. But 4 cores should be enough for anything you can do on a desktop computer.

Some video editors have only 4-cores, but there is no reason to believe that most video editing programs can only be run on a 4-core processor. Because, A six-core machine is required for real-time or even faster editing, as it’s CPU bound. You can edit a single clip in real-time without any problem with a four-core processor.

4-Core vs. 6-Core for Modeling and Rendering?

I think the number four core and six core should be related to the number of processors on the computer. In this case, I guess it means that there are four threads to handle one model or one render. However, the six core would refer to six threads working simultaneously, so a single model/render would take more time. I don’t think it has anything to do with rendering in Unity.

For me, the 4-Core seems to be a better choice. There are many advantages and disadvantages to choosing one or another. Generally speaking, if you have 2-3 TeraFLOPS, the difference is insignificant. If you have 4 Teraflops, then it is an advantage. The 6-core model is better for 3D-type modeling (like 3DS Max). You could create 3D models with the 6-core model and export them directly into 3D Max.

The difference is mainly because of the CPU model, either 32-bit or 64-bit. When it comes to rendering, 4-core has a higher frame rate than 6-core. This is because there are more processors on a 4-core machine, and therefore, there is less overhead when running multiple processes simultaneously. However, on a 6-core machine, each core will run as fast as four cores, so the difference in frame rates is minimal.

If you want to model and render a human character with great detail in 3D, a 6-core CPU is required. However, in a real-life situation, the CPU is usually not the only limitation on the performance, and the available hardware resources are often the limiting factor. For example, your CPU can handle only 4 threads at a time. Thus, if the maximum number of threads that the software allows is less than 4, the program is limited.

Recap & Conclusion

CPU stands for central processing unit, and it is used for computing and processing. CPU cores are divided into two types – processing units and cache memories. Processing units compute logical operations like Addition, Subtraction, Multiplication, and Division. Cache memories store recently-used data to be used immediately without accessing main memory. Each core has its dedicated processing unit and cache memories. Each cache memory is divided into 2 banks or lines.

The main difference between 4-core and 6-core is that a 6-core will run 4 processes simultaneously, while a 4-core will run 2 processes simultaneously. A 6-core will be better for 3D modeling and rendering, while a 4-core will be better for video editing.

If you want to play video games on a modern computer, most people would recommend getting a system with at least 4-cores (4 CPUs or processing units).

The number of cores is an important factor in the computer’s overall performance. However, it’s not the only factor. Other factors can affect the computer’s performance, such as the processor speed, the RAM, and the hard disk speed.

I think it’s a good idea to always look at the specifications of the computer before you buy it. Another thing to remember is that you can’t predict the performance of a computer. Some computers will be slow to start up, and others will be fast to start up. There is no way to know how fast or slow the computer will be in the future.
