GPU Core Clock Vs Memory Clock

For information on a monitor, graphics cards employ the RAM type of the primary CPU. Apart from the CPU, this is your bread and butter if you’re a gamer or a video editor.

Images cards have various clock rates that impact performance, but memory speed determines how quickly graphics are shown on screen. 

Your visuals will be jerky or sluggish if your GPU does not have enough memory. The name of the GPU, the core clock speed, the quantity of onboard VRAM, and the VRAM clock speed are all listed.

This article will discuss the differences between GPU Memory Clock vs. GPU Core Clock, each impact, and how to adjust them.

GPU Memory Clock

The GPU memory card may hold at higher clocks if the Power Management is not set to Adaptive or Optimal. You should also check whether the monitors you’re using demand a higher pixel clock from the GPU than the idle frequency allows (usually 139 Mhz – 253 Mhz).

Memory Clock Speed

The GPU Memory Clock Speed refers to how quickly a graphics card can read and write data from its memory. This value will mainly impact how quickly your images are displayed on the screen, so make sure it’s as high as possible for best results. Games and other graphics-intensive chores may not run as smoothly if your GPU Memory Clock Speed is low.

Speed Effects On Another Part Of GPU

The Memory Clock on the GPU Other aspects of your graphics card, such as the game’s resolution and texturing, are affected by speed, although this is less significant than the speed at which it shows on screen. It will mainly affect the number of frames per second (fps) at which your game operates.

How To Increase Speed Of GPU

GPU speed is generally measured in MHz, and the more excellent the number, the better the performance. Memory Clock on the GPU Purchase a graphics card with extra RAM or overclock your present one to operate faster than its native speed to boost speed. However, keep in mind that this increases power consumption and may shorten the lifespan of your card.

Does Memory Clock Speed Affect FPS In Games

In most situations, overclocking your GPU memory clock will result in a bit of performance boost; however, this varies from game to game. Some games benefit from VRAM frequency more than others, and those others don’t appear to appreciate it as much.

In most situations, overclocking your GPU memory clock will result in a very modest speed boost; however, this varies from game to game. So, GPU Memory Clock might impact FPS from 1% to 10%, depending on whether you’re playing games.

Of course, faster components are always preferable — if you can afford them. However, for most people, RAM speed is not essential to CPU, GPU, and storage performance, and it’s always preferable to have more RAM than faster RAM.

GPU Core Clock 

Your graphics processor’s GPU core clock speed determines how quickly it can, well, process graphics. Therefore, overclocking your GPU core clock will always directly impact the number of frames per second you receive in games.

GPU Core Clock Speed

On the other side, the GPU core clock speed is the rate at which your GPU processes data. When it comes to picture quality and resolution, the core clock will make a difference in how many frames per second you can play games at, but it is not as significant as the GPU memory clock.

If the base speeds aren’t high enough, the core clock can rise by adding extra graphics cards or overclocking an existing one.

Role At Higher Core Clock Of GPU

A higher core clock speed will give you a greater frame rate, allowing you to play games at higher settings, but you must also balance the GPU memory clock speed to maintain excellent picture quality. 

Increasing speed is relatively safe to do so. However, if you go too far, your games may crash, and other issues will occur because your GPU will not receive enough power to run at core clock speed; in this case, either increase power or lower core clock speed.

Push the Power Limit slider all the way up in MSI Afterburner (or your other overclocking program). Set the Temperature Limit slider to whatever you like (the maximum is typically okay, but you may go a bit lower if you’re extra cautious). Then, by roughly 10MHz, increase your Core Clock.

Does Core Clock Speed Affect FPS In Games

Because bigger is better, this will be the most valuable figure on your graphics card. The quicker your core clock, the higher the FPS games will run. However, this only holds when comparing the same graphics card to a different card model because various cards have various components and build structures.

Your graphics processor’s GPU core clock speed determines how quickly it can, well, process graphics. Therefore, overclocking your GPU core clock will always directly impact the number of frames per second you receive in games.

GPU Core Clock Vs Memory Clock | Difference

Here are mentions some facts to analyze the best option between the GPU Core Clock vs. Memory Clock. The primary distinction is that the graphics processor core clock determines how rapidly it can do computations, whereas the memory clock determines what data is available for processing.

You’ll need enough GPU RAM on your computer to accomplish any work in a graphically intense game or software without experiencing issues like lagging frames or choppy gameplay.

If there isn’t enough visual ram (VRAM), a higher than necessary GPU memory clock speed may not assist, resulting in performance problems? 

Many would argue that the CPU has considerably less influence on gaming than either does separately, yet they are critical when playing graphically heavy games.

Between the GPU Core Clock vs. Memory Clock, the core clock takes preference over the memory clock. The memory clock is less significant than the core clock. However, in general, on cards with insufficient RAM (DDR2, for example), there may be more beneficial in OCing the RAM than the CPU, as the latter creates a bottleneck.

Over the GPU Core Clock vs. Memory Clock, the core clock indicates how many GPU executes per second. In most cases, the core clock has a more significant impact on performance than the memory clock, especially in games. Conversely, a memory clock has a more substantial effect on memory-intensive applications than a core clock.

Core Clock (MHz) — the core GPU speed, may generally be adjusted to -75 or -100 without impacting performance. Memory Clock (MHz) – The essential parameter for mining is the memory clock. Some cards have a frequency range of up to 800 MHz!

Overclocking Play Important Role For Both GPUs

Overclocking your graphics card allows you to raise both the core clock vs. memory clock, which, as previously stated, can affect the number of frames per second you can process and play games.

However, if your base speeds aren’t too low, overclocking may not be worth it because each percentage point gained in overclocking results in about a doubling in power usage. It may soon lead to high cooling needs or heat generation, increasing power consumption and reducing the card’s lifespan.

Memory is just as essential as the GPU clock in games with terabytes of textures, if not more so. Try a 10% boost or a 50-100 MHz boost.

If your computer crashes or games exhibit strange abnormalities at these low overclocks, it’s either because your hardware wasn’t meant to be overclocked in the first place. Alternatively, you may need to raise the temperature limit.

The only way that overclocking may shorten a component’s lifespan is to generate more heat for the overclock. That’s all there is to it. There won’t be a substantial change in life duration if you can keep the GPU’s average temperature the same as it was designed to function.


GPU clock speed is critical for getting the most out of your video card, and understanding it may help you make better decisions whether buying a new computer or upgrading an old one.

As a result, a faster memory speed should have an impact on performance in most games. Due to various system constraints, specific GPUs won’t be able to detect or utilize their maximum rated speeds, but this shouldn’t hinder your ability to enjoy gaming as long as you’re using components with adequate power for the game’s needs.
