Did i miss something? Where was this low vs high settings? In what game?

This guy is an idiot. He can't even think.

He could just go to the Ashes leaderboards and check there that polaris cf can match a 1080. But no let's flame on youtube comments like all the fanboys.

And the guy has 600K subs.. I though there was some new benches i missed. But it turns out the guy just has no common sense, Lol. I though the image quality difference was put to bed long ago.

Still doesn't explain why he said loses and was on low. I wonder how his RX 480 review will go, positive or negative? rolleyes.giftongue.gif

There are two models the C4 and the C7 announced so far. The C4 and the C7. The C7 has a clockspeed of 1266MHz and is known as the RX 480. In 3D Mark.. its performance is similar to a Radeon Fury though folks are using its TFlops figures in order to place it as an R9 390 replacement (not understanding that AMD have optimized their GCN cores and caches in order to boost efficiency in that metric not unlike the nVIDIA Kepler to Maxwell changes).. This leaves the door open for an RX 480x which should have 2560 cores compared to the RX 480s 2304 cores. The RX 480 and 480x both having 64 ROPs. I am thinking that we are going to see Radeon FuryX performance out of the RX 480x.

36 CUs leaves us with 144 Texture Mapping Units for the RX 480 and 40CUs leaves us with 160 Texture Mapping Units for the RX 480x. The RX 480x will probably go for $249-$279. This leaves the door open for a $349 and a $399 set of products which will be based on small Vega (RX 490 series) as well as the premium big Vega GPUs which are likely to be priced at $549 and $650 respectively (RX Fury-like lineup).

The RX 490 series will be going head to head with the GTX 1070 and 1080 offerings from nVIDIA while the big Vega GPUs will likely shoot for GTX 1080 Ti and Titan territory.

So the performance per CU is up big time. We will have to wait for the NDA lift in order to ascertain by just how much (I figure that a good chunk of that 30-40% IPC boost is from the changes to the CUs organizational structure). That being said... the RX 480 series are limited by their use of GDDR5. This could be particularly true for the RX 480x.

And he have official confirmation about the quality now smile.gif

Might as well post it...

Hi. Now that I'm off of my 10-hour airplane ride to Oz, and I have reliable internet, I can share some insight.
System specs:
CPU: i7 5930K
RAM: 32GB DDR4-2400Mhz
Motherboard: Asrock X99M Killer
GPU config 1: 2x Radeon RX 480 @ PCIE 3.0 x16 for each GPU
GPU config 2: Founders Edition GTX 1080
OS: Win 10 64bit
AMD Driver: 16.30-160525n-230356E
NV Driver: 368.19
In Game Settings for both configs: Crazy Settings | 1080P | 8x MSAA | VSYNC OFF
Ashes Game Version: v1.12.19928
Benchmark results:
2x Radeon RX 480 - 62.5 fps | Single Batch GPU Util: 51% | Med Batch GPU Util: 71.9 | Heavy Batch GPU Util: 92.3% GTX 1080 – 58.7 fps | Single Batch GPU Util: 98.7%| Med Batch GPU Util: 97.9% | Heavy Batch GPU Util: 98.7%
The elephant in the room:
Ashes uses procedural generation based on a randomized seed at launch. The benchmark does look slightly different every time it is run. But that, many have noted, does not fully explain the quality difference people noticed.
At present the GTX 1080 is incorrectly executing the terrain shaders responsible for populating the environment with the appropriate amount of snow. The GTX 1080 is doing less work to render AOTS than it otherwise would if the shader were being run properly. Snow is somewhat flat and boring in color compared to shiny rocks, which gives the illusion that less is being rendered, but this is an incorrect interpretation of how the terrain shaders are functioning in this title.
The content being rendered by the RX 480--the one with greater snow coverage in the side-by-side (the left in these images)--is the correct execution of the terrain shaders.
So, even with fudgy image quality on the GTX 1080 that could improve their performance a few percent, dual RX 480 still came out ahead.
As a parting note, I will mention we ran this test 10x prior to going on-stage to confirm the performance delta was accurate. Moving up to 1440p at the same settings maintains the same performance delta within +/-1%.

So the GTX 1080 is the one rendering less quality... lol

Great news for us hardware enthusiasts.

Polaris is not aimed at enthusiasts but more the mainstream segment.

You don't have to spend big to be an enthusiast you know...but yes it is aimed at the mainstream segment biggrin.gif.

The RX 490 series will be going head to head with the GTX 1070 and 1080 offerings from nVIDIA while the big Vega GPUs will likely shoot for GTX 1080 Ti and Titan territory.

So the performance per CU is up big time. We will have to wait for the NDA lift in order to ascertain by just how much (I figure that a good chunk of that 30-40% IPC boost is from the changes to the CUs organizational structure). That being said... the RX 480 series are limited by their use of GDDR5. This could be particularly true for the RX 480x.

While on the topic of lackluster YouTubers, i don't know why some of these members don't start their own channels.. If i had half the knowledge some of you folks have, I'd have 1Million subs within 2 years, guaranteed. tongue.gifbiggrin.gif

The biggest problem is that they compare the theoretical TFlops to get a comparison. All the previous GCN cards have really high peak Tflops performance but on games they can't peak so high.

I suspect that polaris can hit the peak performance much easier than fiji.

Also i suspect that polaris is so small because it's mostly a gaming card.

Sure its more affordable but those who wan progress as in, raw performance they only have the 1080 to choose from.

and you are still speaking about your enthusiast world only.

980 performance was like 2 years old, well ya, to the people who can afford it at that time.

Those who want progress? Progress from where?

the 1% wants progress from 980Ti

the other 99% saw hope that the new GTX 960 and 970 equivalents on the AMD side are going to be a lot cheaper, bring great competition to the table

I have always been at the $250 - $350 range when it comes to GPU, and I am very happy to see this aggressive pricing of RX 480.

I've been looking for second hand 960 for roughly $160 USD and 970 for roughly $230 at my local second-hand exchange site for a month or two. Upon seeing this, I kind of feel that I could probably just switch to red team for this and call it a day.

Precisely. GCN4 is what I have been sharing with everyone here. That means a higher efficiency rating than previous GCN architectures. We are really looking at Fury performance under heavy compute conditions out of RX 480.

RX 480 is the C7. The C4 is a smaller variant (RX 470x most likely).



Here is a screen shot of the RX 480 configuration info..
