[WCCF] AMD RX 480 Can Hit 1.5Ghz+, New Overclocking Tool With Voltage Control Coming - Page 252

Can't wait to see these 1600mhz cards pwn the 1080 for 1/3 the price!!!! biggrin.gif

1070 effective die size is not 70% of the 1080. The effective die size of the 1070 could be 90% that of the 1080, pure speculation on my part though, but it most certainly isn't 70%.

Also comparing to Polaris10 in performance/mm^2 isnt so easy because the 480 has ACEs and hardware scheduling.

Anyhow, about the 1060 performance - Nvidia won't be able to compete at the same price. Hopefully they undercut Polaris10 and we can all enjoy mainstream cards at a bargain.

Nvidia is quiet about the 1060 because it can't compete card against card.

GTX 1080 Cuda Cores = 2560

GTX 1070 Cuda Cores = 1920

1920 / 2560 = .75

A 20 second trip to Newegg can find the Cuda Core counts of both GPUs. You just made up some numbers to bolster your claim. Man, you are lazy.

I think you missed the point of what he was saying. CUDA cores aren't the only consideration when comparing die sizes between the 1070 and 1080...

I need to clarify one thing though, he didn't specifically claim that he did 1.6ghz on air, what he said is that so far the highest achievable clock on air is 1.6ghz, but who did it nobody knows since he didn't say he did it. Sorry for that.

He did a preview yesterday though, I just make simple summary here.

+No more frame pacing/stuttering on single card(not crossfire setup), especially on Blizzard games, he said the smoothness on RX480 is better than 970, probably the best experience among all AMD cards so far.

+Don't judge the performance on all the leaks, it's because all those leaks most likely run on old driver, which's not supported the RX480. The only RX480 supported driver so far is 16.6.210038, the so called nda driver, it has exclusive setting for RX480, without it RX480 is trash lol.

+Some of the Wattman features are still locked, and will be unlocked in near future, you can forget about AB. biggrin.gif

+Very good PCB and materials on RX480, just compare to 1070 and you can see the different. A bit overkill.

-The reference cooler is ok if you're not intended to overclock, but still not a good reference cooler, or else wait for AIB.

Performance wise he can't say much due to nda, but he did imply that it's slightly below 980.

^ is he on that Rx480 driver? When comparing with gtx980?
post #2516 of 2870
When he says slightly below 980, does he mean synthetics or real world performance? Also, is there no overclocking headroom on the reference models? Or is it just limited? 1300/1350mhz would be a decent enough boost to lift it above "980" levels, correct?

Hard to get to 1600 when you can't get to 1400. I kinda wanna see what a custom card is going to do. I think power consumption shoots to the moon when you try to OC (typical GCN).

Fine - the 1070 is a 1080 with 25% of the Cuda Cores and TMUs cut - actually bolsters my claim, thanks!

This does not mean that the effective die size of the 1070 is 75% that of the 1080 because only a portion of the chip was cut.

Polaris 10 wins in performance/$ and wins in performance/mm^2 ( stupid Nvidia fanboy metric btw ). It may may come very close in performance/watt; could possibly take this too, but it's pretty difficult for a mainstream part to accomplish this.

Point is the 1060 is in hiding and it's pretty clear why Nvidia isn't talking about it.
post #2519 of 2870
When he's implying the performance close to 980, I would assume default vs default. Pretty sure RX480 is definitely faster than 970, I think he was forced to come out to clarify because recent leaks indicated that RX480 is slower than 970.

Edit : I think just wait for official reviews drop is the best thing to do now, different result from different source lol.

Some retailers are already selling these cards apparently so it won't be long now before we start finding out exactly how it does. I can't wait until the members here on OCN start getting their cards and posting up benchmarks!
