Performance Position & Market Ranking

Released in 2016, the Radeon RX 455 OEM ranks #333 out of 640 graphics cards in our benchmark database, positioning it in the top 52% (48th percentile) of all evaluated GPUs. In rasterization and compute throughput, it places immediately behind the Radeon RX 460 Mobile (DPI score 43) and just above the GeForce GTX 965M 4 GB (DPI score 43). Featuring GCN 2.0 architecture with 2 GB GDDR5 on a 128-bit interface, it achieves a verified DPI catalog score of 43/100.

A CPU bottleneck occurs when the graphics card is waiting on the processor to calculate physics, game logic, and draw calls, leaving the GPU underutilized. Conversely, a GPU bottleneck happens when the processor is ready with frames, but the graphics card cannot render them fast enough.

When building a PC with the Radeon RX 455 OEM, selecting the right CPU ensures smooth frame times, high 1% lows, and eliminates stuttering. Using our DPI performance engine, we have analyzed various processor pair combinations to find the exact component that will maximize your system's output. Whether you prefer high-refresh 1080p competitive gaming or stunning 4K visuals, balancing the Radeon RX 455 OEM is the key to an optimal experience.

Resolution Scaling

The Radeon RX 455 OEM behaves differently depending on the target resolution. At 1080p, it will often wait for the CPU, making a fast processor critical for high frame rates. As you move to 1440p and 4K, the bottleneck shifts naturally to the GPU as the rendering workload increases substantially.

This card is best suited for 1080p Gaming scenarios.It balances well at 1440p, requiring a modern mid-range CPU to utilize fully.

Frequently Asked Questions

Why does this build show this bottleneck result?

This build pair shows a result because the Radeon RX 455 OEM reaches its limit first at 1440p/144Hz. In AAA Gaming scenarios, this component determines your maximum performance ceiling.

What does a 15% bottleneck mean?

A 15% bottleneck is classified under our canonical scale as a Moderate Variance (10–20%). It indicates that one component waits on the other for approximately 15% of computation cycles during peak load, determining system equilibrium.

How do resolution and refresh rate affect bottlenecks?

Lower resolutions (like 1080p) and high refresh rates increase pressure on the CPU to prepare frames quickly. Higher resolutions (like 4K) shift the heavy lifting to the GPU for rendering. Adjusting these balances the load.

What should I upgrade first for this build?

Your Radeon RX 455 OEM is the limiting factor. Upgrading your graphics card or lowering game settings/resolution will yield the biggest performance gains.

Are bottleneck scores exact?

Use these scores as a guide. Results are estimates; real performance varies by game, settings, drivers, RAM, and thermals. Always verify with real-world benchmarks for your specific titles.
