Consider the following when you shop for graphics cards:

  1. Choose a GPU that suits based on the software you are intend to use it.
  1. For example, playing game in 4K, you may need a graphics card with high clock speeds and large VRAM. You rendering may even need multiple graphics cards in the same Workstation.
  1. Always check compatibility with software and never undertake rentals without first conducting detailed research into what you need. Match your GPU with the existing components and understand your bottlenecks.
  2. While choosing Mobile Workstation laptop with a powerful GPU is that size of laptop will be bulky and drain the battery and graphics not as powerful as Workstation.
  3. Graphics card GPU creates lot of heat. When you are creating or upgrading your PC and be sure to allow space for the requisite cooling systems.
  4. If you are buying/ renting Workstation, it is advisable to allocate between 30-35% of your budget to the GPU.

GPU Performance

GPUs enable visuals and reduce the strain on your CPU so it can focus on essentials that will improve your computer’s performance. The GPU performances are based on:

  • Clock speed (MHz or GHz): The GPU performance and higher speeds are good for visuals and higher frame rates. While comparing clock speeds in cards of the same generation by the same manufacturer.
  • VRAM (GB): VRam supplied with data so that it doesn’t have to communicate with the slower system memory or hard drive. Lower VRAM as insufficient memory will seriously affect performance.
  • The type and bandwidth of the GPU’s VRAM is also equally important. GDDR5 VRAM, for example, is always preferable to GDDR4.

Types of GPUs

The type of graphics card that you need depends on how you use your computer. There are two main types, namely shared and dedicated. Their differences and strengths are as follows:

  • Shared graphics is when graphic tasks are performed by a chip that shares its memory with the RAM and other CPU components. These GPUs generate less heat and use less power than dedicated graphics, making them a sensible choice for laptops.
  • Computers with dedicated graphics feature a separate processing unit that takes responsibility for all graphic related tasks from the CPU. These units are optimised to deliver better visuals, relief to the CPU and a faster performance all round.
  • If you don’t game or work with high resolution media, shared graphics may be all you need. However, if your needs are more advanced, you are always likely to benefit from using a computer with a dedicated GPU

AMD Graphics Cards

AMD is leading brand in GPU technology and their processors. when making your choice, find out:

  • Crossfire – this feature allows you to install several, compatible GPUs in your PC and harness the combined power of all them for a considerable performance boost compared to that delivered by a single card.
  • FreesyncAMD GPUs feature advanced technology that resolves communication issues between the processor and compatible monitors to remove tearing and stuttering for flawless visuals.
  • Eyefinity – this technology allows you to work or game across as many as 6 screens so you can enjoy an immersive experience like no other.

NVIDIA Graphics Cards

NVIDIA is monopoly player in the GPU market and offers products with advanced features that are exclusive to the NVIDIA range, such as:

  • SLI – this technology allows you to install up to three, compatible GPUs in your PC and harness the power of all them for a radically improved performance and higher image quality.
  • G-Sync – this visual technology helps you immerse yourself in smooth, tear-free gaming at up to 240Hz. To enjoy this feature look for G-Sync enabled GPUs, monitors and laptops.
  • DSR (Dynamic Super Resolution) – this technology renders games at a higher resolution before shrinking the results to suit you monitor so you can enjoy a 4K experience on a Full HD screen.
