If you watch AdoredTV he talks about this, its called ndivia mindshare. How nvdias marketing so so good, even during the fermi days, when AMD had better software, and hardware nvidia still managed to hold 50% of the market. AMD only took like 6-7% more.

AdornedTV is one of the best tech channels on YouTube.

factory OC'ed RX480 with 2 six pins running at 1500mhz
even IF a stock 1266 Mhz 480 = 980 (and thats an if in my book), then + ~240 Mhz OC to 1500 will only put it at best @ half-way between 980 and stock 980Ti .. and stock 1070 > stock 980Ti


so yes, I dont see any way 480 competes with 1070 except with a lower price for lower performance

Not to further derail the thread, but the 1070 beats the 980ti by a good margin at $375. As of right now, imo, that guys offer is a fair price. When both cards drop, $300 will sound generous. 2cents.gif


Good odds to see RX480 benches within 2 weeks? 1 month seems way too long and no leaks.

Oh I am willing to bet nvidia will still come out on top. Heres my prediction:

Nvidia annouces and teases specs of 1060 just days before RX480 launch.
Youtube "tech channels" rant and rave and hype it, and ultimately tell people to hold off because the 1060 is just around the corner.
RX480 launches and gets fair reviews but mediocre sales.
GTX1060 launches, youtube reviewers rave at its power efficiency and talk about how it competes with RX480.
GTX1060 sells 2-3x as much as the RX480
Youtube reviewers make a heartfelt statement how they wish AMD could get back some marketshare to promote competition.

And dont even pull out a Ashes benchmark, that is the only thing that AMD has.

Take a look at 3DMark11 scores. They seem pretty indicative of performance. The 1266MHz clock that was confirmed seems to match up perfectly with this entry.

We can see that the C7, or RX 480 has performance near a R9 Fury with 2304 cores.

Now it's all but guarunteed that the Vega 10, with roughly 400mm size die, will have exactly 4096 cores. Even if Vega 10 only uses GDDR5X, it would be highly unlikely that the Vega chip would lose out to a 300mm chip even if Nvidia's architecture is still far ahead of AMD's. If the C7 with a mere 2304 cores is matching the R9 Fury's score even though it has 1280 less cores, what reason would you have to think that the same wouldn't ring true for Vega? We can compensate for clockspeed as well to get a look at actual architecture improvements....

2304 cores vs 3584 cores...

that's a 55.5% increase in core count, while1266mhz is obviously a 26.6% increase in clock speed.

We can use extremely lazy and bad math to assume that architecturally, and before clock speeds are applied, that Vega 10 will have roughly 29% improvement from IPC alone, We can take the Fury X score of 19315 and increase it by 29% to get a score of 24,916. That's significant unto itself, but not as significant as AMD has advertised. So even at a horribly low clock of only 1050Mhz, the theoretical Vega chip will perform just under the 1080. If we are to increase this clockspeed to what the P10 chip's stock clock is, we end up with just above a 20% increase in overall performance..... Leaving us with a score just under 30,000, The GTX 1080 is handily beat. So obviously what it will come down to is what speed AMD is able to clock these GPUs in at.With AMD cards in the past, overclock scaling is pretty spot-on, while that doesn't always mean that you are guaranteed to reach them. However, if AMD is not capable of 1.2GHz on a 14nm, 400mm card, AMD is essentially finished.

The RX 480 will have 980 performance roughly, at 1500mhz compared to stock 1266Mhz it should be able to compete* with, not match* the 1070, it will be within 10% performance, of course overclocking the 1070 will result in a larger lead for the 1070. similiar to how the 980 Ti and titan are able to compete with the 1070. If we take the leaked 3DMark score for an RX 480 and increase it by the percentage of the overclock, we end up with 21,398, which is a score between a 980 Ti and Titan for 3DMark. 1500MHz is completely plausable for the RX 480, although heading towards the upper limits of what the chip will be able to handle.

There's also the issue of whether or not the overclock will result in a linear improvement in performance, or like the 1080/1070, it loses steam as clocks get higher. Let's imagine a full P10 chip is released after yields are dealt with, and has the same clocks as the RX 480. It should have a score of 20,066. Which will put it at 980 Ti levels, similiar to what old rumors had suggested. Now imagine a best (and I mean BEST case scenario) Where a full P10 chip is released that clocks in at 1.5GHz. (This would be extremely shocking to see). At this best-case scenarion, this proposed "perfect polaris" could actually edge out a 1070. Although again, I didn't account for how the architecture scales with clock speeds and extra cores.

my post is obviously making some assumptions but I think you'll come to see that it's not entirely based on complete and utter bull

Well AMD comments at the recent investor meeting indicate Polaris is for both mainstream and performance markets, but they plan to target mainstream first.

"Polaris will ramp over a series of quarters, as we nail that performance and mainstream portion of the market...".


"...and the things we want to achieve in the near-term for this product launch to go to mainstream first, and then proliferate product upwards and downwards, up into enthusiast and down into value..."

You don't need to guess, he says it himself that he is an Nvidia fanboy.

However, I've never seen AMD results from him that are out of line with what I myself have seen in my own buying/overclocking endeavors. He also started the channel on an AMD FX 8350 rig and only changed to Intel when the video editing became too much.

If proliferating the product upwards means the same wait we had for the Pro Duo, we're all doomed.

Two sides of the same coin right there. Take anything either says with a dump truck of salt.

Don't hold me to this as it's just some estimates based on what info we have available, but for thoughts on about the whole RX 480 v 1070 thing....

*Using leaked 3dmark 11 benchmarks from VC, Gurud 3D review for approximate performance scaling of Hawaii 390X (scaling is almost linear ~.95), and Guru3D review of 1070 FE

Best case of relative 20% oc for the RX 480 (I would expect a slightly less total percentage based on memory OC limitations for GDDR5 @ 8ghz stock).

1266 -> 1520mhz

3Dmark 11 GPU score @ stock - 18060

18060 x 1.2 x .95 = GPU score of 21491

_________

Approximate 3Dmark 11 GPU score for 1070 FE @ ~2050 (9% performance increase based off stock 3Dmark 13 run vs ocd 3Dmark 13 run)

23663 x 1.09 = 25,800 GPU score

_________

RX480 vs GTX 1070FE @ theoretical max OC's

(25800 x 100)/ 21491 = 120 or the GTX 1070 would still be approximately 20% quicker in 3Dmark 11

*Must do this to pass time before they get released, so sick of waiting when I actually have free time to play some games mad.gif. This card may actually have the potential to outpace a stock Fury X @ 1080 if it has OC potential.
