CMP 40HX

2021

Why buy it

✅More future proof: Turing (2018−2022) on 12nm with a newer platform for upcoming games.
✅Measures 229mm instead of 241mm, a 12mm shorter card that is more SFF-friendly.
✅More future proof: Turing (2018−2022) on 12nm with a newer platform for upcoming games.

Trade-offs

❌Less VRAM, with 4 GB vs 8 GB for high-resolution textures and newer games.
❌No equivalent frame-generation stack like FSR Frame Generation (2023).
❌
205.2% HIGHER MSRP
$699 MSRPvs$229 MSRP
❌Lower G3D Mark per dollar, at 12.5 vs 38.4 G3D/$ ($699 MSRP vs $229 MSRP).

Radeon RX 580

2017

Why buy it

✅Costs $470 less on MSRP ($229 MSRP vs $699 MSRP).
✅Delivers 207% more G3D Mark for each dollar spent, at 38.4 vs 12.5 G3D/$ ($229 MSRP vs $699 MSRP).
✅Access to a newer frame-generation stack with FSR Frame Generation (2023).
✅100% more VRAM for high-resolution textures and newer games (8 GB vs 4 GB).

Trade-offs

❌Poor future-proofing: 2017-era hardware with 8 GB of VRAM is already a legacy-tier option for modern games.

Quick Answers

So, is Radeon RX 580 better than CMP 40HX?

Yes. Radeon RX 580 is clearly the better overall GPU here. You are also looking at 8,799 vs 8,749 in G3D Mark. On top of that, Radeon RX 580 is a 2017 card with FSR upscaling + limited Frame Generation, while CMP 40HX is a 2021 model from an older generation with no meaningful modern upscaling stack. So this is not really a tight same-tier comparison. It is more a modern card against an older, weaker alternative.

Which one is more future-proof for 2026 and beyond?

CMP 40HX is the more future-proof choice for 2026 and beyond. You are getting a newer 2021 generation instead of 2017, the stronger feature stack with no meaningful modern upscaling stack instead of FSR upscaling + limited Frame Generation, and a 12nm process instead of 14nm. That broader feature stack should age better as more games lean on modern upscaling and frame-generation support.

Which one is the smarter buy today, not just the cheaper card?

Radeon RX 580 can still make sense if you find it at the right price, especially around $229 MSRP. Radeon RX 580 is still the smarter buy for most people, though, because the raw performance is close while the overall package is cleaner. Radeon RX 580 is about $470 cheaper on MSRP at $229 MSRP versus $699 MSRP, and you are getting 0.6% higher G3D Mark. CMP 40HX is the newer 2021 card, so it still has a real case if you care more about newer architecture and future-proofing than about squeezing out the strongest gaming value today.

When does CMP 40HX make more sense than Radeon RX 580?

Yes. CMP 40HX is still an excellent gaming GPU in 2026: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. It makes more sense if your priority is newer architecture, future-proofing, and staying closer to $699 MSRP more than squeezing out the extra headroom of Radeon RX 580. The trade-off is that Radeon RX 580 currently gives you 0.6% higher G3D Mark. It also leads G3D-per-dollar by 207%.
