Arc B770 vs Radeon RX 9070 XT
A side-by-side readout for 3dmark time spy.
Understanding 3dmark time spy
Time Spy renders a fixed scene with tessellation, volumetric lighting, and async compute, then reports a graphics score, a CPU score, and an overall composite.
Score bands (graphics score, desktop)
- Entry 1080p card: 6,000–9,000
- 1440p sweet spot: 12,000–18,000
- 4K-capable: 18,000–25,000
- Halo (RTX 4090, RX 7900 XTX): 28,000+
Why we use it
- Cross-vendor (NVIDIA and AMD score on the same scale).
- Reproducible (locked workload).
- Maps well to actual 1440p frame rates in modern titles — a 25% Time Spy lead typically translates to a 20–25% in-game lead.
Limitations
It does not include ray tracing (Port Royal does) or upscaling. A card with strong rasterization but weak RT can win Time Spy and lose path-traced Cyberpunk.
This matchupRadeon RX 9070 XT's 19200 is roughly 42% higher than Arc B770's 13500 (a 5700 gap). Whether that gap is noticeable depends on workload — small percentage gaps rarely change day-to-day experience, while gaps of 20% or more usually do.
