    Erdekes, hogy 4K-nal elhuz a 3080, aztan hwunboxed elmagyarazta miert.
    Nem teljesen CPU bottleneck van a dolgok mogott:

    We've looked deeper at the RTX 3080's performance at 1440p, so we want to comment on that. As far as we can tell, CPU bottlenecking alone is not the explanation. The reason comes down to Ampere's architecture and the change to the SM configuration that we mentioned in the introduction. The 2x FP32 design can only be fully utilized at 4K and beyond. This is because at 4K the portion of the render time per frame is heavier on FP32 shaders. At lower resolutions like 1440p, the vertice and triangle load is identical to what we see at 4K, but at the higher resolution pixel shaders and compute effect shaders are more intensive and take longer and therefore can fill the SMs FP32 ALUs better.

    Tehat 4K-ban jon ki a 2x FP szam a regiekhez kepest.
    Meg nem lehetetlen, hogy a 3090 valoban eleg lesz a kovetkezo generaciog 4K-ban.
    Viszont aki kisebb felbontasra veszi ott nem lesz annyia seggre ulos a kulonbseg.
    Ez valahol jo, valahol nem, a 10GB Vram 4K-hoz nem eleg, pedig maga a VGA eleg lenne.
    Kell a tobb vram annak aki ezt 4K-ra veszi, ugyesen kitalaltak megint :)
