[WCCF] AMD RX 480 Can Hit 1.5Ghz+, New Overclocking Tool With Voltage Control Coming - Page 215

Keep in mind that this is the first time in history of GPU product launches that a new mid-grade chip didn't meet or exceed the performance of a previous generation top tier offering.
See above. thumb.gif

Since when is a $700 1080 a mid-grade card (or even a $450 1070 for that matter)? And since when do you compare performance of a $200 budget card with that of a flagship? This card is not a replacement for the 390X. It's launching for half the price of the 390X for God sake!

Are you finished? I could do this all night...

Huh that's actually a good point. thinking.gif

Well the 390X also has 50% higher memory bandwidth (384 GB/s vs 480's 256 GB/s), so I guess we can say the memory compression is worth at least that much.

I don't get why when AMD attempts a small die gpu to capture the low - mid GPU market people say its a fail as its not like nvidia with their 50% larger die beating the last gen by 10% (1080 only).

If AMD had a 1080 sized die then yes , they should get a bollocking and rightly so for not getting similar gains vs last gen like nvidia.

AMD didn't turn up to the big GPU fight with this GPU. I doubt any reviews will state they did either (apart from Hardocp ...)

Vega is the gpu that will compete with the 1070/1080 and beyond , i would like it to be here right now but we just have to wait. Its not like NV released anything to get excited about if you own 980ti or TX .. so yeah there is no upgrade paths really for the top end of either camp yet.

No it isn't a good point. The 480 at $200 is not a mid grade product. Hell, I paid more for my 560Ti back in 2011 and it didn't even match a 470, much less the 480...

That's straight from Tonga.
The R9 285 with 176GB/s bandwidth had more effective bandwidth than Hawaii.

AMD would have to sell a $200 480 that beats The 1080 by 50% in order for the fanboys to ever give them any credit. And even then they would probably say that the cooler was a cheap piece of trash. rolleyes.gif
If it was R9 Nano or Fury Air performance, I would be happy. That's a decent uArch improvement.

This is why "mid-grade" is a terrible term for Gx104 chips. P10 and GP104 are in very different size categories, so your comparison doesn't make any sense. A bigger Polaris at ~310-320mm^2 would give a 980 Ti a run for its money, too, but since P10 is very similar in size to Pitcairn rather than GK104/Tahiti/whatever, it's not going to get that kind of performance.

NV's competition to Polaris 10 is GP106, which we haven't seen in any way, shape, or form yet. AMD's competition to GP104 is Vega 10, which again, we haven't seen yet. Comparing GP104 to Polaris 10 is like comparing Pitcairn to GK104.

980ti cores - 2816

1080 cores - 2560

Now think about how high the clock speed has to be on the 1080 to make a significant increase in performance.

Nothing spectacular there either.

If you look at perf/mm^2, it should have been in Fury X territory in comparison to Pascal. So saying "small die" doesn't save it from an engineering stand point.

Exactly. Nvidia HAD to get 1800+MHz out of GP104 just to beat the 980Ti. There is no architectural performance increase with Pascal vs Maxwell; it's all node shrink and clock speed advantage.

You could sell a turd for a low price, doesn't mean it's not a turd.

I'm looking at it strictly from the engineering standpoint. If it's 390x performance, zero uArch improvements in shader efficiency have been made.
