GPU Compare — Compare Graphics Cards Side by Side

How to Compare GPUs Effectively

Choosing the right graphics card is one of the most important decisions when building or upgrading a gaming PC. The GPU directly determines how many frames per second you get in games and at what resolution you can play comfortably. Our GPU comparison tool lets you place up to four graphics cards side by side, comparing real-world gaming performance, specifications, power consumption, and value metrics.

When comparing GPUs, raw specifications like clock speeds and CUDA core counts only tell part of the story. A GPU with fewer cores but a more efficient architecture can outperform one with higher specs on paper. That is why we rely on aggregated benchmark data from real gaming tests rather than theoretical performance numbers. Our data pulls from publicly available benchmarks across dozens of popular games at 1080p, 1440p, and 4K resolutions.

Pay special attention to the resolution you plan to game at. A card that dominates at 1080p may struggle at 4K, while a card with more VRAM and higher memory bandwidth will scale better to higher resolutions. If you are gaming on a 1440p 144Hz monitor, prioritize cards that can consistently deliver 100+ FPS at that resolution in your most-played games.

Understanding GPU Specifications

VRAM (Video Memory)

VRAM stores textures, frame buffers, and game assets that the GPU needs quick access to. For 1080p gaming, 8GB of VRAM handles most modern titles comfortably. At 1440p with high-quality textures, 12GB provides headroom for demanding games like Cyberpunk 2077 and The Last of Us Part I. For 4K gaming or future-proofing, look for 16GB or more. Running out of VRAM causes stuttering as the GPU swaps data to slower system RAM.

Clock Speeds (Base and Boost)

GPU clock speed, measured in MHz, indicates how fast the processor cycles through instructions. The base clock is the guaranteed minimum frequency, while the boost clock is the maximum the card reaches under load with adequate cooling. However, comparing clock speeds between different GPU architectures is misleading — a lower-clocked NVIDIA GeForce card can match or beat a higher-clocked AMD Radeon card due to differences in IPC (instructions per clock).

TDP and Power Consumption

Thermal Design Power (TDP) indicates how much heat the GPU generates under load, which directly corresponds to power draw. A 250W TDP card needs a PSU with enough headroom — generally your total system draw plus 20-30% buffer. Modern high-end GPUs also experience transient power spikes that can momentarily exceed their rated TDP by 50-100W, so a quality PSU with good transient response is important. Use our PSU Calculator to estimate your power supply needs.

Memory Bandwidth

Memory bandwidth measures how quickly the GPU can read and write data to VRAM, calculated by multiplying the memory clock speed by the bus width. Higher bandwidth is especially important at elevated resolutions (1440p and 4K) where larger frame buffers and textures need to move in and out of memory rapidly. Cards with wider memory buses (256-bit, 384-bit) generally handle high-resolution workloads better.

Ray Tracing Performance

Hardware ray tracing simulates realistic lighting, reflections, shadows, and global illumination. NVIDIA RTX cards use dedicated RT cores for this workload, while AMD RDNA 3 and Intel Arc cards use their compute units. Ray tracing performance varies significantly between architectures — check our benchmarks for RT-specific FPS data. Pairing ray tracing with upscaling technologies like NVIDIA DLSS or AMD FSR helps maintain playable frame rates.

GPU Performance Tiers Explained

Graphics cards fall into distinct performance tiers based on their target resolution and frame rate. Understanding these tiers helps you avoid overspending on a card that exceeds your monitor capabilities or underspending on one that cannot keep up.

Frequently Asked Questions

Which GPU is best for 1440p gaming in 2026?

For 1440p gaming at high refresh rates, the RTX 5070 and RX 9070 XT offer excellent performance. For a budget-friendly option, the RTX 4070 or RX 7800 XT still delivers strong 1440p performance. Use our comparison tool above to see how they stack up in your favorite games.

NVIDIA vs AMD: Which brand should I choose?

NVIDIA excels in ray tracing performance and offers DLSS for AI-powered upscaling, which is available in more games. AMD typically provides more raw rasterization performance per dollar and FSR works across all GPUs. If ray tracing matters to you, lean NVIDIA. If raw FPS per dollar is your priority, AMD is often the better value.

How much VRAM do I actually need?

For 1080p gaming, 8GB is sufficient in 2026. For 1440p with high textures, 12GB gives comfortable headroom. For 4K or heavy modding, 16GB is recommended. Games are using more VRAM each year, so buying more now provides a longer usable lifespan.

Is ray tracing worth the performance hit?

In games with excellent RT implementations like Cyberpunk 2077, Alan Wake 2, and Metro Exodus Enhanced Edition, ray tracing dramatically improves visual quality. With DLSS 3 or FSR 3 frame generation, the performance cost is manageable on mid-range and higher GPUs. On budget cards, you may want to keep RT off and enjoy higher frame rates instead.

What PSU wattage do I need for my GPU?

High-end GPUs like the RTX 4090 and RTX 5080 recommend 850W or higher PSUs. Mid-range cards like the RTX 4070 or RX 7800 XT work well with a 650W PSU. Budget cards such as the RTX 4060 or RX 7600 run on 500-550W. Always account for transient power spikes and leave 20-30% headroom above your estimated total system draw.

Should I wait for next-generation GPUs?

If your current GPU still meets your needs, waiting is reasonable. However, there is always something newer on the horizon. Current-generation cards offer excellent performance, and used or discounted previous-gen cards can be outstanding value. Buy when you need an upgrade rather than chasing the next launch.

What is the difference between DLSS, FSR, and XeSS?

DLSS (NVIDIA) uses dedicated AI hardware for the highest quality upscaling. FSR (AMD) is an open standard that works on any GPU, including NVIDIA and Intel cards. XeSS (Intel) offers AI-accelerated mode on Intel Arc GPUs and a fallback mode for others. All three technologies boost frame rates by rendering at a lower internal resolution and intelligently upscaling to your display resolution.

How important is memory bandwidth for gaming?

Memory bandwidth becomes increasingly important at higher resolutions. At 1080p, most modern GPUs have sufficient bandwidth. At 4K, a card with higher bandwidth can access textures and frame buffer data faster, preventing bottlenecks. Cards with wider memory buses (256-bit or 384-bit) generally offer better bandwidth than those with narrower 128-bit buses, even at the same memory speed.
