Hello everyone!

So i'm targeting the true gurus of GPUs on this site. I'm building my first PC and all the components have been bought except the GPU. First I have to say that at this point after studuying all the new GPUs including custom cards, even considering the prices I would prolly go with the 1070. But as it stands I have bought a freesync monitor already and want to believe that the technology is worth having (my gaming is mostly CS:GO) so I'm stuck with AMD.

So after reading all the possible reviews, benchmarks and so on about the 480 as well as 1070 and 1080 there's couple of big questions I have about the specs.

rx 480 has nice amount of shader units although I have understood that those can't be compared to Nvidia numbers, because of the different architecture. But the one question I am yet to find an answer is why does the new rx 480 have 32 ROPs, which is the lowest number in any GPU compared to last gen AMD cards as well as any recent nvidia card. And more importantly, how does it effect performance as I have understood it's mostly responsible for AA which is off anyway in many games where you want a high fps number. But even if it's not THE most important spec it's prolly a big reason why rx 480 is doing surprisingly bad on benchmarks (comparing to r9 390 and gtx 970/980), because those are done with ultra settings. Am I right here?

The other number where rx is lacking is the compute units which is 36 in 480, right? So that would feel like a big compromise as well regarding power of the GPU.

So could some expert give me a round up of the matters I've discussed here and especially what I'm supposed to think about it. As I said after inspecting everything I would really like to go with a 1070/1080 and probably with a gsync monitor but that combination would add ~500$ compared to my current freesync monitor+ strix rx 480 (when it arrives). So should I just be happy about the money saved here or has AMD done really unfortunate compromises with their new card?

My own opinion atm is that allthough I'm now "stuck" with AMD because of the monitor I've already bought and the money saved, the rx 480 really feels like a fixed-term solution. Ofc there the possibility to go crossfire if the power is not enough. And to those going to say you need zero power for cs:go, I will play other games like the rise of the tomb raider so power is appreciated to some extent. And by fixed-term I mean much shorter time than with 1080 or 1070.

Thank you in advance for everyone and although every answer is appreciated I also would like to hear about the decisions made by AMD and how those effect.

I have no idea how to answer your question about 32 ROPs. I'm not a pro at that. Even with Freesync only be able to activate at certain FPS, having something more (positively) is always better, right? Don't regret your monitor decision. If you're able to buy a GTX 1070, you should be able to buy 2 RX 480s, which blow GTX 1070 out of the water at games that support multi GPUs. Those are my opinions

Yeah that's exactly what I've been thinking to do! And I do know it's a budget GPU, that was probably their only option if you think how good the 1080 is. I just personally would have liked to see the rx 480 maybe cost 50 or even 100$ more and at least wipe out the old gtx's and 390.

I just really hope that AMD will make a truly excellent card that really can even better the 1080 and not make compromises in the high-end model as well.

By improving per core efficiency, you're able to to more with less cores, it's a trick both camps use to get overall power usage down. My 780ti has almost 2900 cuda cores (keplar), but looses to a 980 that has 2k cuda cores (maxwell) using less power, you could say the same thing adding in the 10 series or amds old to new gen.

For me nvidia is more consistent where AMD has some solid victories in certain scenarios hence a 390x/480 taking turns winning/loosing to 980 and to each other even. You actually don't need variable refresh rate as much if you're going high end and know how to tune your games so they don't dip, you can use 75hz/85hz or more on gaming and as long as you don't dip you're still getting a very fast/smooth experience. Even with gsync I don't like dipping down as it's not as smooth and you want your game to be consistent and smooth all the time.

Hey man thanks for your answer I appreciate it! Yeah I'm honestly pretty ok with my monitor choice and the good thing is as you said I will always have the option to switch to crossfire anytime I feel like I need more power. Although has to be said I've heard little mixed things about the crossfire and I personally would prefer one card. But that's not a problem at all and at least now I dind't have to splash the cash immediately :b

You mean gsync is not smooth and you prefer no sync at all? And in cs:go if I play at 128 tick servers I do need to get at least that in fps so I want to use the full potential of my 144Hz monitor

I prefer G-sync on, with as little as 65fps or more things start to get really really smooth, it also makes lower fps like 45-60 feel A LOT better than a fixed refresh rate 60hz with vsync on or off.

If you get a 1070 you can still run high hz without variable refresh rate, you just have to tune your games so they don't dip in fps which it sounds like you do that already as a CS:GO player.

If you got the 480 already, it's all good and I would keep it, only return it if you need what the 1070 offers in performance. I'm assuming you're at 1080p? If so 480 is plenty. Going back to my first post don't feel bad about lower specs that still perform better, that is how you lower cost (and power usage) improving performance per dollar.

Yeah 1080p. The freesync/gsync will drop little in fps but probably should still be way over 145fps, at least that's what I hope. And yeah will leave the most fps consuming stuff of in settings if that's what you mean by dip. And yeah I know that the 480 will be just fine so I'm all good in that perspective
