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

Radeon RX 640

2019

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 13.7 vs 0 G3D/$ ($159 MSRP vs Unknown 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 Unknown).
✅UHD Graphics Xe 750 32EUs 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.
❌233.3% higher power demand at 50W vs 15W.

UHD Graphics Xe 750 32EUs

2021

Why buy it

✅Draws 15W instead of 50W, a 35W reduction.

Trade-offs

❌Less VRAM, with Unknown vs 4 GB for high-resolution textures and newer games.
❌No equivalent frame-generation stack like FSR Frame Generation + AFMF (2023).
❌2021 hardware with Unknown 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 13.7 G3D/$ (Unknown MSRP vs $159 MSRP).

Quick Answers

Which GPU is faster for gaming right now?

UHD Graphics Xe 750 32EUs is the faster gaming card right now based on the synthetic data we have. It leads by 1.3% in PassMark G3D (2,200 vs 2,172), 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 Unknown of VRAM and the newer feature stack, with FSR 3 (2023) and FSR Frame Generation + AFMF (2023), while UHD Graphics Xe 750 32EUs is limited to no meaningful modern upscaling stack and no comparable frame-generation support. 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 today based on the pricing and value data we have for this matchup. UHD Graphics Xe 750 32EUs still makes more sense if max raw gaming performance matters more than value.
