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

GeForce GTX 555

2011

Why buy it

✅100% more VRAM for high-resolution textures and newer games (1 GB vs 512 MB).

Trade-offs

❌Lower average FPS than Radeon 540X across 50 tracked games in our benchmark data.
❌2011 hardware with 1 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌
51.5% HIGHER MSRP
$150 MSRPvs$99 MSRP
❌Lower G3D Mark per dollar, at 10.7 vs 16.0 G3D/$ ($150 MSRP vs $99 MSRP).
❌40% higher power demand at 70W vs 50W.

Radeon 540X

2018

Why buy it

✅30.2% more average FPS across 50 tracked games in our benchmark data.
✅Costs $51 less on MSRP ($99 MSRP vs $150 MSRP).
✅Delivers 50% more G3D Mark for each dollar spent, at 16.0 vs 10.7 G3D/$ ($99 MSRP vs $150 MSRP).
✅GeForce GTX 555 is already obsolete for modern gaming, so Radeon 540X is the less risky modern option long term.
✅Draws 50W instead of 70W, a 20W reduction.

Trade-offs

❌Less VRAM, with 512 MB vs 1 GB for high-resolution textures and newer games.
❌2018 hardware with 512 MB of VRAM already sits in legacy territory for modern games.

Quick Answers

Which GPU is faster for gaming right now?

Radeon 540X is the faster gaming card right now. In our data, it leads by 30.2% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward GeForce GTX 555 instead at 1,604 vs 1,588, so for this question the real-game FPS result matters more than the synthetic split.

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

Radeon 540X is the safer long-term pick for 2026 and beyond. The case is simple: the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, a 14nm process instead of 40nm, and a newer 2018 generation instead of 2011. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

Radeon 540X makes the most sense to buy today. It is $51 cheaper on MSRP at $99 vs $150, and it leads G3D-per-dollar by 50% (16.0 vs 10.7), so the value case lines up with the gaming result.
