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

GeForce GTX 645

2010

Why buy it

✅Costs $249 less on MSRP ($150 MSRP vs $399 MSRP).
✅Measures 147mm instead of 240mm, a 93mm shorter card that is more SFF-friendly.

Trade-offs

❌Lower average FPS than GeForce RTX 4060 Ti across 50 tracked games in our benchmark data.
❌Less VRAM, with 1 GB vs 8 GB for high-resolution textures and newer games.
❌No equivalent frame-generation stack like DLSS 3.5 + Frame Generation (2023).
❌2010 hardware with 1 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 12.5 vs 56.8 G3D/$ ($150 MSRP vs $399 MSRP).

GeForce RTX 4060 Ti

2023

Why buy it

✅558.9% more average FPS across 50 tracked games in our benchmark data.
✅Delivers 352.9% more G3D Mark for each dollar spent, at 56.8 vs 12.5 G3D/$ ($399 MSRP vs $150 MSRP).
✅Access to a newer frame-generation stack with DLSS 3.5 + Frame Generation (2023).
✅700% more VRAM for high-resolution textures and newer games (8 GB vs 1 GB).
✅Better long-term bet: Ada Lovelace (2022−2024) on 5nm gives it a newer hardware base for upcoming games.

Trade-offs

❌63.3% longer card at 240mm vs 147mm.

Quick Answers

Which GPU is faster for gaming right now?

GeForce RTX 4060 Ti is the faster gaming card right now. In our data, it leads by 558.9% in average FPS across 50 tracked games in our benchmark data and by 1104.8% in PassMark G3D (22,651 vs 1,880), so the answer here is pretty clean.

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

GeForce RTX 4060 Ti is the safer long-term pick for 2026 and beyond. The case is simple: 8 GB vs 1 GB of VRAM, the newer feature stack, with DLSS 3.5 Super Resolution (2023) and DLSS 3.5 + Frame Generation (2023), while GeForce GTX 645 is limited to no meaningful modern upscaling stack and no comparable frame-generation support, a 5nm process instead of 40nm, and 34 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 4060 Ti makes the most sense to buy today. It is $249 more expensive on MSRP at $399 vs $150, and it leads G3D-per-dollar by 352.9% (56.8 vs 12.5), so the value case lines up with the gaming result.
