GeForce RTX 3070

2020

Why buy it

✅1116.6% more average FPS across 50 tracked games in our benchmark data.
✅Delivers 100+% more G3D Mark for each dollar spent, at 44.4 vs 0 G3D/$ ($499 MSRP vs Unknown MSRP).
✅Access to DLSS 2 Super Resolution (2020).
✅100% more VRAM for high-resolution textures and newer games (8 GB vs 4 GB).
✅Better long-term bet: Ampere (2020−2025) on 8nm gives it a newer hardware base for upcoming games.

Trade-offs

❌633.3% higher power demand at 220W vs 30W.

Quadro K620M

2015

Why buy it

✅Draws 30W instead of 220W, a 190W reduction.

Trade-offs

❌Lower average FPS than GeForce RTX 3070 across 50 tracked games in our benchmark data.
❌Less VRAM, with 4 GB vs 8 GB for high-resolution textures and newer games.
❌No DLSS support; it relies on Upscaling support instead.
❌2015 hardware with 4 GB 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 0 vs 44.4 G3D/$ (Unknown MSRP vs $499 MSRP).

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 1116.6% in average FPS across 50 tracked games in our benchmark data and by 1813% in PassMark G3D (22,172 vs 1,159), 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 4 GB 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 today based on the pricing and value data we have for this matchup.
