Introduction

The graphics processing unit (GPU) started life as a chip for drawing images on a screen. Today, it is one of the most powerful components in any computer. GPUs render 3D designs, edit and encode video, accelerate photo editing, power games and, increasingly, run artificial intelligence workloads. The same technology that drives a designer’s workstation also powers the world’s AI data centres.

For businesses, choosing the right graphics depends on the work. Most office computers are well served by integrated graphics built into the processor. Designers, architects, engineers, video editors and AI developers need dedicated graphics cards with more power and memory.

Raiden (Pvt) Ltd, an authorised reseller for HP, Dell, Lenovo and other leading brands, supplies business computers, workstations and graphics solutions across Sri Lanka, and supports them through its Annual Maintenance Contracts (AMC), including peripherals such as monitors.

This article explains how GPUs work, the latest generations from NVIDIA, AMD and Intel, AI features such as upscaling and frame generation, how much video memory you need, how to choose graphics for business roles, and how Raiden’s AMC supports graphics-intensive systems.

What a GPU does

A CPU has a small number of powerful cores designed for a wide variety of tasks. A GPU has thousands of smaller cores designed to perform many calculations in parallel. This makes GPUs ideal for:

• Rendering graphics: 3D models, games, user interfaces and visual effects.
• Video: editing, effects and encoding into formats such as H.264, HEVC and AV1.
• Photo editing: filters and AI-based enhancements.
• Engineering and science: simulations and calculations.
• AI: training and running AI models, which rely on parallel calculations.

Integrated versus dedicated graphics

Integrated graphics have improved enormously. Intel’s Xe3 graphics in Core Ultra Series 3 processors, AMD’s Radeon integrated graphics and the large integrated GPUs in AMD’s Ryzen AI Max processors can handle light design work and even some gaming. For demanding professional workloads, however, dedicated graphics remain essential.

The latest graphics generations

NVIDIA GeForce RTX 50 series (“Blackwell”)

NVIDIA launched its GeForce RTX 50 series, based on the Blackwell architecture, in early 2025. Key features include:

• GDDR7 video memory, offering higher bandwidth.
• DLSS 4, including Multi Frame Generation, which uses AI to generate additional frames for smoother performance in supported games and applications.
• Improved ray tracing for realistic lighting.
• Enhanced AI performance through Tensor cores.
• Updated video encoders supporting modern formats.

NVIDIA also offers professional RTX PRO graphics based on Blackwell for workstations, with larger memory and certified drivers for professional applications. A refreshed RTX 50 “Super” range has been widely expected, but industry reports in 2026 describe it as delayed, partly because of rising memory costs.

AMD Radeon RX 9000 series (“RDNA 4”)

AMD launched the Radeon RX 9070 XT and RX 9070 in early 2025, based on the RDNA 4 architecture. They brought:

• Significantly improved ray tracing performance.
• FSR 4, AMD’s AI-based upscaling technology.
• Strong value in the mid-to-high-end segment.

AMD also offers Radeon PRO graphics for professional workstations. Its next-generation architecture is reported to be expected in 2027.

Intel Arc (“Battlemage”)

Intel’s Arc B-series graphics cards, launched from late 2024, offer good value with modern features, including AI upscaling (XeSS) and strong video encoding. Intel also offers Arc Pro professional cards for workstations.

AI upscaling and frame generation explained

Modern GPUs use AI to improve performance and image quality:

• Upscaling renders an image at a lower resolution and uses AI to reconstruct it at a higher resolution, with little visible loss of quality. NVIDIA’s DLSS, AMD’s FSR and Intel’s XeSS are the main technologies.
• Frame generation uses AI to create additional frames between rendered frames, making motion smoother.

These technologies are best known in games but are increasingly used in 3D visualisation and real-time rendering applications.

VRAM: how much video memory do you need?

VRAM (video memory) stores textures, 3D models, video frames and AI models. If a workload needs more VRAM than the card has, performance drops sharply.

Professional versus consumer graphics cards

Many CAD and engineering applications are certified only on professional graphics cards. Check software requirements before choosing.

Choosing graphics for business roles

Power, connectors and cooling

High-end graphics cards draw a lot of power and generate heat. They need:

• A quality power supply with enough capacity and the right connectors. Many modern cards use the 12V-2×6 connector introduced with the ATX 3.1 power supply standard, a revised version of the earlier 12VHPWR design (see Computer Power Supplies in 2026: ATX 3.1, 12V-2×6, Efficiency Ratings and UPS Protection).
• Good airflow inside the case.
• Regular cleaning, because dust on graphics card fans and heatsinks causes overheating and noise.

In Sri Lanka’s warm climate, keeping graphics cards clean and well ventilated is particularly important. Raiden engineers clean and check graphics cards during preventive service visits.

Display outputs and multiple monitors

Graphics cards and integrated graphics provide outputs such as HDMI and DisplayPort. The latest cards support DisplayPort 2.1, which enables very high resolutions and refresh rates. Multi-monitor setups improve productivity for many roles, and modern graphics easily drive two or more displays. Computer Monitors in 2026: OLED, High Refresh Rates, USB-C Docking, Eye Care and Business Displays explains monitors in detail.

Video encoding and the AV1 format

Modern GPUs include dedicated video engines that encode and decode video efficiently. Support for AV1, a modern, efficient video format, helps with streaming and producing high-quality video at smaller file sizes. For businesses producing video content, webinars and training materials, hardware encoding speeds up exports dramatically.

GPUs and AI in business

AI is becoming part of everyday business software, from image generation and transcription to data analysis. Some tasks run on the NPU in modern processors (see Computer Processors (CPUs) in 2026: AI PCs, NPUs, Hybrid Cores and How to Choose the Right CPU); heavier tasks run on the GPU or in the cloud. Businesses experimenting with local AI models, for privacy or cost reasons, need GPUs with plenty of VRAM. Raiden can advise on whether local GPUs or cloud services are better for each use.

The 2026 market

The graphics market in 2026 is shaped by AI demand. Data centres consume large volumes of high-end GPUs and memory, and rising memory prices have affected graphics card costs and the timing of new products. Industry reports describe delays to some expected refreshes. Planning purchases carefully, and choosing graphics that match real workloads rather than buying the most powerful card, gives the best value.

Signs of graphics problems

Graphics drivers: why updates matter

Graphics drivers are the software that lets the operating system and applications use the GPU. Updated drivers fix bugs, improve performance, add support for new applications and close security holes. However, the newest driver is not always the best choice for business. For professional applications, certified studio or enterprise drivers, tested with specific software versions, provide the most stable experience. During preventive maintenance, Raiden engineers check driver versions and update them carefully, keeping certified drivers on professional workstations.

Remote graphics and virtual workstations

Some organisations now run demanding graphics workloads on powerful machines in a server room or the cloud, and staff connect remotely from lighter laptops. This approach, often called virtual workstations, lets designers and engineers work from anywhere while the heavy processing happens centrally. It requires fast, reliable networks and careful planning, but it can reduce the need for powerful hardware on every desk. Raiden can advise on whether local workstations or remote approaches suit a business best.

Caring for graphics hardware

• Keep drivers updated, using certified drivers for professional applications.
• Clean dust from fans and heatsinks regularly.
• Ensure good airflow and avoid placing computers in enclosed cabinets.
• Use a quality power supply with the correct connectors, fully inserted.
• Use a UPS for workstations, to protect long renders from power cuts.
• Monitor temperatures during heavy work; sustained high temperatures shorten component life and cause slowdowns as the card protects itself.
• Check cables and adapters, as loose or low-quality display cables cause flicker and signal loss, especially at high resolutions and refresh rates.

Laptops with dedicated graphics

Many business laptops are available with dedicated graphics for designers, engineers and video editors on the move. These “mobile workstations” combine a powerful processor, a dedicated GPU and a high-quality display. Their GPUs are usually lower-powered versions of desktop cards, and their performance depends heavily on the laptop’s cooling design. Because they run hot, regular cleaning of vents and fans is especially important, and they benefit from being used on hard surfaces or laptop stands. For users who need maximum performance at a desk and portability when travelling, a capable laptop with a docking station and external monitors is a popular choice.

Graphics for multi-screen operations and signage

Some businesses use graphics hardware for more than desk work. Control rooms, CCTV monitoring stations, retail displays, menu boards and reception screens all rely on graphics to drive multiple displays reliably, often around the clock. For these uses, look for graphics with enough outputs, support for the required resolutions and stable drivers. Raiden can supply and support computers for signage and monitoring, and its AMC covers CCTV devices and peripherals such as monitors.

Upgrading graphics in existing computers

Adding or upgrading a graphics card in a desktop can extend its life for creative and technical work, but several checks are needed:

1. Space: will the card physically fit? Many business small form factor PCs accept only low-profile cards.
2. Power: can the power supply deliver enough power, with the right connectors?
3. Slot: is there a suitable PCIe x16 slot?
4. Cooling: is there enough airflow for the extra heat?
5. Platform: will an older processor limit the new card’s performance?

Raiden engineers can check these points and recommend whether an upgrade or a new workstation is the better choice.

An example in practice

The following example is illustrative and does not describe a real client.

An architecture firm’s designers waited minutes for 3D models to update, and renders often crashed overnight. Their computers used consumer graphics cards with limited memory and uncertified drivers.

Raiden reviewed the firm’s CAD and rendering software and supplied workstations with professional graphics cards certified for its applications, plus UPS units for long renders. Under an Enterprise Shield AMC, the workstations receive regular cleaning and driver updates, and the firm’s overnight rendering is protected by 24/7 support. Model updates are now fast, and renders complete reliably.
