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

GeForce 845M

2015

Why buy it

✅45.6% more average FPS across 50 tracked games in our benchmark data.
✅More future proof: Maxwell (2014−2017) on 28nm with a newer platform for upcoming games.

Trade-offs

❌2015 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Radeon HD 7770M

2012

Why buy it

✅Competitive enough if your priority is price, power, or specific feature preference.

Trade-offs

❌Lower average FPS than GeForce 845M across 50 tracked games in our benchmark data.
❌2012 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Quick Answers
