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

GeForce GT 640 Rev. 2

2013

Why buy it

✅Costs $70 less on MSRP ($99 MSRP vs $169 MSRP).
✅Draws 49W instead of 70W, a 21W reduction.
✅Measures 145mm instead of 160mm, a 15mm shorter card that is more SFF-friendly.

Trade-offs

❌Lower average FPS than GeForce RTX 3050 6GB across 50 tracked games in our benchmark data.
❌Less VRAM, with 512 MB vs 6 GB for high-resolution textures and newer games.
❌No DLSS support; it relies on Upscaling support instead.
❌2013 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 11.8 vs 63.6 G3D/$ ($99 MSRP vs $169 MSRP).

GeForce RTX 3050 6GB

2024

Why buy it

✅777.1% more average FPS across 50 tracked games in our benchmark data.
✅Delivers 439.1% more G3D Mark for each dollar spent, at 63.6 vs 11.8 G3D/$ ($169 MSRP vs $99 MSRP).
✅Access to DLSS 2 Super Resolution (2020).
✅1100% more VRAM for high-resolution textures and newer games (6 GB vs 512 MB).
✅Better long-term bet: Ampere (2020−2025) on 8nm gives it a newer hardware base for upcoming games.

Trade-offs

❌42.9% higher power demand at 70W vs 49W.
❌10.3% longer card at 160mm vs 145mm.

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 777.1% in average FPS across 50 tracked games in our benchmark data and by 820.3% in PassMark G3D (10,749 vs 1,168), 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 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 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 to buy today. It is $70 more expensive on MSRP at $169 vs $99, and it leads G3D-per-dollar by 439.1% (63.6 vs 11.8), so the value case lines up with the gaming result.
