R9 280x vs. GTX 970. is the performance gap this huge?

post #1 of 16
Thread Starter 
i benched them in the same settings maxed out at 1080p for a good comparison. didn't think it would be almost 40% weaker than a gtx 970 I expected it to be a bit closer. both are overclocked to the max and I think 1145mhz core is a good OC for an r9 280x correct?

r9 280x (1145/7000) vs. gtx 970 (1545/7500)


the r9 280x rig only had an i3 2120 but with heaven the gpu load was maxed all the time so I don't think the cpu is an issue. I would really appreciate if someone can post a Heaven run with the same settings. TIA OCN thumb.gif

I upgraded my i3 2120 to an i5 3470 + h77 chipset.




not much of a difference in unigine heaven (within margin of error imo) but other games greatly improved. far cry 4 was 30-40fps with the i3 2120. now it's 60fps with just the occasional stutter thumb.gif

The 970 compares well with the 780 / 780ti, which when released were equally faster than the 7970 / 280x, so i do not think that it is some unusual difference. All's good there

This doesn't surprise me at all...
  1. The 280x is based on significantly older tech
  2. The 970 costs a lot more (£180 for a 280x and £260)

Although I would have expected them both to perform a lot better in this test.

with this graph it's about 27% faster than an r9 280x at 1080p and afaik maxwell doesn't scale that well with overclocking AND heaven isn't one of its strong benchmarks. I do think the overclock I have with this 280x is no slouch.

was expecting a bit more with the 280x tbh. i'm a bit dissapointed tbh but I bought this from a friend for about 150USD so I guess it's fine

would really appreciate is if someone would post a heaven run with their 280x. maybe there's a software issue or just the omega drivers acting up

that's why I thought it would be closer. I had a gtx 780 before and it beats the 970 (both overclocked to the max) the 970 overall had a slight edge with "real" games but it's a bit weak with this benchmark

Just bench them in the same rig to remove the rest of variables first. Afaik CPU still plays a small but measurable part in heaven.

I wouldn't want to mess up the drivers with my main rig so that is out of the question. I'm thinking of upgrading my htpc it with a quad core (like an i5 2400/2500) I'll try a second run and see if it does make a big difference

tbh I doubt the i3 is making a difference. I had an OSD at the background and the gpu load was 99% all the time.


+reps btw ty

a bottleneck is noticeabke on unigine so the comparison should be done with similar cpu

Unigine is known to be tesslation heavy and is really only for benching Nvidia GPUs. That's why 780Ti hit 90 fps range while the 290X is mostly in the 70s. 3D mark is more appropriate for comparing AMD with Nvidia GPUs.

P.S. The cpu might have something to do with it but i'm not 100% sure about that.
