GPUs are at the heart of every desktop computer, laptop, and even most affordable tablets and smartphones do have one. While CPUs remain the core for processing power, the GPU (graphics processing unit) is the central unit responsible for accelerating graphics rendering.
From running your Windows Aero up to the latest PassMark and AIDA64 Extreme, your GPU does the job of processing graphics data more than CPUs. If you’re buying a cheap and good laptop in Singapore, you might wonder what graphics card suits you. Here are a few factors you should consider when choosing a laptop’s GPU:
1. Discrete or integrated
A number of laptops have integrated GPUs or built graphics cards that are built into the processor, such as Intel Iris and Ryzen’s iGPU. Mid to high-end laptops and even affordable smartphones have discrete GPUs. Discrete GPU is separated from the CPU. To put it bluntly, discrete GPUs are more powerful but expensive.
2. Clock speed
With AMD’s Big Navi and the latest Nvidia Ampere Architecture series of the 3000s, most graphically demanding triple-A games are enough to handle these latest GPUs. However, not every cheap and good laptop in Singapore does have the latest discrete cards, which have higher clock speeds. Clock speed is the metric for defining a GPU performance.
3. Overclocking ability
Several graphics card architecture and CPUs (such as Intel’s K-marked processing units) allow overclocking. Overclocking is done by modifying the core’s and memory’s clock to boost the unit’s performance. Though, it should be done with knowledge and guidance.
4. Memory
Unlike every affordable tablet or smartphone, most laptop graphics units have a variety of memory that depends on their architecture. This virtual memory is used to store display information. If you’re planning to run the latest triple-A games or perform video or 3D rendering tasks, consider going for at least 6 to 8GB GDDR6 variants.
