See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.

HD Graphics P630

2016

Why buy it

✅Draws 15W instead of 50W, a 35W reduction.
✅More future proof: Generation 9.5 (2016−2020) on 14nm with a newer platform for upcoming games.

Trade-offs

❌Less VRAM, with Unknown vs 2 GB for high-resolution textures and newer games.
❌2016 hardware with Unknown of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Radeon HD 8790M

2013

Why buy it

✅100+% more VRAM for high-resolution textures and newer games (2 GB vs Unknown).
✅HD Graphics P630 is already obsolete for modern gaming, so Radeon HD 8790M is the less risky modern option long term.

Trade-offs

❌2013 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌233.3% higher power demand at 50W vs 15W.

Quick Answers

Which GPU is faster for gaming right now?

Radeon HD 8790M is the faster gaming card right now based on the synthetic data we have. It leads by 2% in PassMark G3D (1,306 vs 1,280), which is the best performance signal available in this matchup.

Which GPU is the safer long-term pick for 2026 and beyond?

Radeon HD 8790M is the safer long-term pick for 2026 and beyond. The case is simple: 2 GB vs Unknown of VRAM and the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack. That gives it more room for heavier textures and higher settings over time.
