Reviewed component guides

Start with a reviewed GPU model

Compare graphics cards by resolution target, VRAM context and the workloads that matter to you. Each profile explains where the GPU fits, what to monitor and which CPU pairings are worth testing.

Component matchups

Compare reviewed pairings and find the right match

Explore editor-reviewed CPU and GPU combinations across 1080p, 1440p and 4K. Then use the selection guides to build a shortlist around your resolution, frame-rate target and workload.

Detailed comparisons

CPU and GPU pairing analyses

Open a pairing to compare three resolutions, understand the estimated limiting side and choose a real-world validation test.

Buying direction

CPU selection guides

Start from a component you already own or plan to buy, then compare suitable matches for different performance targets.

How to use this GPU library

Match the graphics card to resolution and settings

A graphics processor shades pixels, processes geometry and handles effects chosen by the game or application. Native 4K contains four times as many pixels as 1080p, but settings, upscaling and ray tracing also change the work. Compare the display target before comparing model tiers.

Separate graphics memory from rendering speed

VRAM capacity helps hold textures, geometry and working data. It does not make two GPUs with the same memory size equally fast. Check allocation, frame time and the effect of one graphics-setting change. The GPU bottleneck guide shows a repeatable test.

What the tier index means

A comparison input, not a benchmark score

The displayed tier index is a normalized input for this site's directional model. It is not a vendor specification, promised frame rate or universal product ranking. Resolution, frame target and workload factors adjust the relative CPU and GPU headroom. Read the full calculation methodology before using a difference as buying evidence.

Why the guide library is curated

The calculator keeps broad model coverage for quick lookup. Detailed profiles are published only when they add a distinct use case, validation plan and useful comparison context.

Three checks before an upgrade

  1. Record frame time, utilization, clocks and temperature in a repeatable scene.
  2. Change one variable, such as resolution or a CPU-heavy setting, and record the response.
  3. Compare the measured limit with the target you actually need, then check compatibility and total upgrade cost.
