Radeon RX Vega 56 vs GeForce GTX 980 Ti: In-Depth Breakdown

Performance: Radeon RX Vega 56 vs GeForce GTX 980 Ti

The Radeon RX Vega 56 is significantly faster, around 20% ahead of the GeForce GTX 980 Ti. Both cards sit in the same broad class, well suited to entry-level 1080p.

Price & Value

Right now the Radeon RX Vega 56 starts at $472 GBP against $700 GBP for the GeForce GTX 980 Ti. Because it's both faster and competitively priced, the Radeon RX Vega 56 wins on performance-per-dollar by about 78%.

Power & Efficiency

The Radeon RX Vega 56 draws just 210W versus 250W for the GeForce GTX 980 Ti, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom. Its more modern GCN 5.0 (Vega) architecture on a GloFo 14nm process is part of why it does more with each watt.

VRAM & Future-Proofing

With 8GB against 6GB, the Radeon RX Vega 56 has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce GTX 980 Ti's 6GB can fall short.

Generation & Longevity

The Radeon RX Vega 56 is roughly 2 years newer than the GeForce GTX 980 Ti (GCN 5.0 (Vega) vs Maxwell), so it generally benefits from a more modern architecture and longer driver-support runway.

Features & Ecosystem

Beyond raw numbers, the GeForce GTX 980 Ti brings NVIDIA DLSS upscaling/frame generation and stronger ray tracing, while the Radeon RX Vega 56 offers AMD FSR upscaling and strong rasterization value. If you lean on upscaling or ray tracing, that ecosystem difference can matter as much as the frame-rate gap.

Which should you buy: GeForce GTX 980 Ti or Radeon RX Vega 56?

The Radeon RX Vega 56 is the all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the GeForce GTX 980 Ti if you find it at a steep discount.

Frequently Asked Questions

Is the Radeon RX Vega 56 better than the GeForce GTX 980 Ti?

The Radeon RX Vega 56 is significantly faster, roughly 20% ahead. If your budget allows, it's the stronger pick.

Which is better for 4K gaming, the GeForce GTX 980 Ti or the Radeon RX Vega 56?

Neither is a dedicated 4K card; both are best at entry-level 1080p. For 4K you'd want a faster GPU, or lean on upscaling.

Is the GeForce GTX 980 Ti worth the extra $228 GBP over the Radeon RX Vega 56?

Only if you need the extra performance or features; on pure value the Radeon RX Vega 56 comes out ahead.

Does the Radeon RX Vega 56 have enough VRAM advantage to matter?

Its 8GB (vs 6GB) gives real headroom for 4K, heavy texture mods, and creative/AI work. At 1080p the gap matters less.
