ASUS GeForce RTX 5080 ProArt 16GB GDDR7
ASRock Arc B580 Challenger 12GB GDDR6
Pick the ASUS ProArt RTX 5080 if you're chasing 4K gaming, heavy ray tracing, or AI workloads and have the cash and an 850W PSU to feed it.
Grab the ASRock Challenger B580 if you're building a mid-range rig on a budget and want solid 1440p performance with 12GB of VRAM without melting your power bill or your wallet.
Key Differences
- Raw performance is not even close: the RTX 5080 scores 35,666 on PassMark vs 16,019 for the B580, and 99 vs 48 in 4K gaming. You're getting roughly double the frames in demanding titles.
- VRAM and memory tech: the RTX 5080 packs 16GB of GDDR7 on a 256-bit bus, while the B580 makes do with 12GB of GDDR6 on a 192-bit bus. That's a real gap for 4K textures and future-proofing.
- Power draw is a huge differentiator: the B580 sips 190W and only needs a 650W PSU, while the RTX 5080 pulls 360W and demands 850W. Your electricity bill and case airflow will notice.
- Price gap is massive. The B580 goes for around $250-300, while the RTX 5080 sits at $999+ MSRP, and real-world pricing often pushes it higher. You could build an entire B580 system for the cost of the 5080 alone.
- Customer sentiment tells an interesting story: the B580 has a 4.5/5 rating from 455 reviews with high confidence, but owners report DOA cards and frustrating ASRock warranty support. The RTX 5080 has fewer reviews (206) and lower confidence, but owners rave about 4K performance and overclocking headroom, with one user hitting 3.3 GHz while staying under 68°C.
