GRID M6-1Q

2015

Why buy it

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

Trade-offs

❌Less VRAM, with 2 GB vs 4 GB for high-resolution textures and newer games.
❌No equivalent frame-generation stack like FSR Frame Generation + AFMF (2023).
❌2015 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌
843.4% HIGHER MSRP
$1,500 MSRPvs$159 MSRP
❌Lower G3D Mark per dollar, at 1.4 vs 13.7 G3D/$ ($1,500 MSRP vs $159 MSRP).

Radeon RX 640

2019

Why buy it

✅Costs $1,341 less on MSRP ($159 MSRP vs $1,500 MSRP).
✅Delivers 890.4% more G3D Mark for each dollar spent, at 13.7 vs 1.4 G3D/$ ($159 MSRP vs $1,500 MSRP).
✅Access to a newer frame-generation stack with FSR Frame Generation + AFMF (2023).
✅100% more VRAM for high-resolution textures and newer games (4 GB vs 2 GB).
✅GRID M6-1Q is already obsolete for modern gaming, so Radeon RX 640 is the less risky modern option long term.

Trade-offs

❌Older hardware, 4 GB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.

Quick Answers

Which GPU is faster for gaming right now?

Radeon RX 640 is the faster gaming card right now based on the synthetic data we have. It leads by 5% in PassMark G3D (2,172 vs 2,069), which is the best performance signal available in this matchup.

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

Radeon RX 640 is the safer long-term pick for 2026 and beyond. The case is simple: 4 GB vs 2 GB of VRAM, the newer feature stack, with FSR 3 (2023) and FSR Frame Generation + AFMF (2023), while GRID M6-1Q is limited to no meaningful modern upscaling stack and no comparable frame-generation support, a 14nm process instead of 28nm, and a newer 2019 generation instead of 2015. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon RX 640 makes the most sense to buy today. It is $1,341 cheaper on MSRP at $159 vs $1,500, and it leads G3D-per-dollar by 890.4% (13.7 vs 1.4), so the value case lines up with the gaming result.
