How Old Processors Stand Against The New Ones
Let’s compare the major differences between the old and new processors to determine if you really are in need of a new one or not. Also after reading the comparison, you will have in-depth knowledge of what you’ll be getting if you buy a new processor.
Features | Old Processors | New Processors |
Cache Size: | Very small in KBs | Up to 100 MBs |
Cores: | Up to 4 cores | Up to 32 Cores or more |
TDP: | Produce more heat | Produce Less Heat |
PCIe: | Supports up to 3.0 | Supports up to 5.0 |
Now that we have gone through the basics, let’s understand the parameters of the table in detail:
- Cache Size: The latest processors come with a cache memory of 60 MB on average while it goes as high as 96 MB. It allows the CPU to quickly retrieve the programs and achieve better performance. The Old CPUs have memory cache memory in KBs means they will take more time to load any program.
- Cores: Classic processors are equipped with either 2 cores or quad cores while new ones have at least 6 and this number goes up to 32 or more. But the question here is how does it make a difference? The number of cores means the processor is able to execute numerous instructions at the same time.
- TDP: The New processor comes with a balanced TDP that ensures that the CPU doesn’t get overheated. This allows them to manage the productivity loads efficiently. On the other hand, the old CPUs when combined with GPU, produce a lot of heat and noise, resulting in the bottleneck and damaging the components.
- PCIe: It is the support of peripheral interconnection of components which is responsible for data transfer rates and bandwidths. The new processors support 5th gen PCIe while the older ones can only accommodate up to 3.0. This results in slower speeds in older processors as compared to the new ones.
4 Features to Consider Before Buying a Best Gaming CPU
Being a gaming consultant, I will suggest some key features that should be considered to end up with a good choice. How to decide and what to choose? Let me help you with it. Listed below are the crucial features to be considered:
1. Cores and Thread Count
The first and most important thing before getting a CPU is the core count and the number of threads. They play a key role in the performance of any CPU and directly affect the performance of a system. Cores handle independent tasks, while threads represent the simultaneous execution of instructions.
In my opinion, a minimum of 6 cores and 12 threads is a must because if you choose a CPU with fewer cores or threads, you will face a major setback in overall performance. So always opt for the maximum cores you can get in a CPU.
2. Clock Speed
Secondly comes the clock speed, which is measured in GHz. It determines how quickly the processor processes the instruction and executes it. A key thing to keep in mind is that the processor with a higher clock speed can outperform the CPU with more cores and less clock speed.
As per my experience, the minimum of 3.0 GHz of a base clock frequency is a must and the max clock speed should be at least 4.5 GHz. Also, you can overclock your CPU to get the most out of it but the power consumption will be more and the CPU will generate more heat.
3. Compatibility
Don’t ever make the mistake of choosing a CPU that is not compatible with your hardware like motherboard, RAM, and GPU. Because if you buy a CPU that is not supported by your motherboard, you will have to purchase a new board for it.
4. Bottlenecking
For GPU to work properly you must do the proper research and see if the considering CPU will bottleneck it. Because if you don’t weigh this factor in, even the best gaming CPU will fail to give you the performance. There are two types of bottlenecking, let me explain them for your ease:
- CPU Bottleneck: If your CPU is more powerful than the GPU, its processing power will be limited. As a result, your CPU won’t be able to give its max and it will be only a waste of resources.
- GPU Bottleneck: When the graphics card is more powerful than the CPU, the GPU fails to utilize its power.
Just keep in mind, if your CPU or GPU is bottlenecking only up to 5%, it’s fine as it doesn’t affect the performance.
