Here are a few cards I’ve tested with i5(4690 k) and fx-6300 processors with the average fps from the logs + rough cost. These are cheap cards but can have nice results on zwift. As cheap as they are, they still out perform most laptop gpu’s
Radeon R7 240- medium (720p) 30-32fps ($ 50)
Radeon R7 250x medium 58fps( fx6300) 60(i5) $80
Radeon R7 250x high 35 fps(i5&6300)
Radeon R7 360 medium and high 58-60 fps(6300& i5) $100
None of these cards give me the ultra option but I’m guessing the r7-360 could run Ultra at a low but playable fps. Especially with minor oc on the 6300. And with Radeon’s virtual super resolution which kinda works a little. It might be worth un-leashing ultra for the R7 360 users. I’m guessing fps would drop to 28-30?
Tomorrow I’ll try the R9 380x with the Fx-6300, which should give me the Ultra option.
The R7 240 is really the lowest I would want to go while the 250x is definitely better. If you have a cheap computer without a extra 6 Pin connector on your power supply then the 250x is worth it. If the power supply doesn’t have a extra external power connector than 240 isn’t a bad 720p gpu.
The 360 should really get the ultra option as its a much better card than the others. If 250x can push the 1080p to 35 fps without a studder. I’m sure the 360 could push ultra. But it would be a waste of money until they do so. Unless you play other online games.
