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

GeForce 840A

2014

Why buy it

✅Costs $399 less on MSRP ($100 MSRP vs $499 MSRP).
✅Draws 33W instead of 220W, a 187W reduction.

Trade-offs

❌Lower average FPS than GeForce RTX 3070 across 50 tracked games in our benchmark data.
❌Less VRAM, with 512 MB vs 8 GB for high-resolution textures and newer games.
❌No DLSS support; it relies on Upscaling support instead.
❌2014 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌Lower G3D Mark per dollar, at 11.2 vs 44.4 G3D/$ ($100 MSRP vs $499 MSRP).

GeForce RTX 3070

2020

Why buy it

✅1061.1% more average FPS across 50 tracked games in our benchmark data.
✅Delivers 298.5% more G3D Mark for each dollar spent, at 44.4 vs 11.2 G3D/$ ($499 MSRP vs $100 MSRP).
✅Access to DLSS 2 Super Resolution (2020).
✅1500% more VRAM for high-resolution textures and newer games (8 GB vs 512 MB).
✅Better long-term bet: Ampere (2020−2025) on 8nm gives it a newer hardware base for upcoming games.

Trade-offs

❌566.7% higher power demand at 220W vs 33W.

Quick Answers

Which GPU is faster for gaming right now?

GeForce RTX 3070 is the faster gaming card right now. In our data, it leads by 1061.1% in average FPS across 50 tracked games in our benchmark data and by 1888.5% in PassMark G3D (22,172 vs 1,115), so the answer here is pretty clean.

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

GeForce RTX 3070 is the safer long-term pick for 2026 and beyond. The case is simple: 8 GB vs 512 MB of VRAM, the newer upscaling stack, DLSS 2 Super Resolution (2020) instead of no meaningful modern upscaling stack, a 8nm process instead of 28nm, and 46 vs 0 ray-tracing units. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

GeForce RTX 3070 makes the most sense to buy today. It is $399 more expensive on MSRP at $499 vs $100, and it leads G3D-per-dollar by 298.5% (44.4 vs 11.2), so the value case lines up with the gaming result.
