GeForce GT 645M

2012

Why buy it

✅Draws 32W instead of 70W, a 38W reduction.

Trade-offs

❌Lower average FPS than GeForce RTX 3050 6GB across 50 tracked games in our benchmark data.
❌Less VRAM, with 2 GB vs 6 GB for high-resolution textures and newer games.
❌No DLSS support; it relies on Upscaling support instead.
❌2012 hardware with 2 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 63.6 G3D/$ (Unknown MSRP vs $169 MSRP).

GeForce RTX 3050 6GB

2024

Why buy it

✅889.2% more average FPS across 50 tracked games in our benchmark data.
✅Delivers 100+% more G3D Mark for each dollar spent, at 63.6 vs 0 G3D/$ ($169 MSRP vs Unknown MSRP).
✅Access to DLSS 2 Super Resolution (2020).
✅200% more VRAM for high-resolution textures and newer games (6 GB vs 2 GB).
✅Better long-term bet: Ampere (2020−2025) on 8nm gives it a newer hardware base for upcoming games.

Trade-offs

❌118.8% higher power demand at 70W vs 32W.

Quick Answers

Which GPU is faster for gaming right now?

GeForce RTX 3050 6GB is the faster gaming card right now. In our data, it leads by 889.2% in average FPS across 50 tracked games in our benchmark data and by 1037.5% in PassMark G3D (10,749 vs 945), so the answer here is pretty clean.

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

GeForce RTX 3050 6GB is the safer long-term pick for 2026 and beyond. The case is simple: 6 GB vs 2 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 18 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 3050 6GB makes the most sense today based on the pricing and value data we have for this matchup.
