[AMD] Polaris based RX 480 and "High performance solutions" announced at computex - Page 78

post #771 of 1394
The thing about bias is everyone has it. Yes, in a perfect world, all reviewers would lack bias, but that is impossible. I like AMD, I have since the K6-2. I loved my Phenom II 1090T. Hell, I loved my ATI 3D Rage II. The only reason I have an 8350 is I got it for under $100 brand new, I was going to go Intel because Intel outperforms AMD at this time.

If all things are equal, I will purchase AMD over the others. However, I acknowledge that bias. Do two 480's outperform the 1080? We will see, we don't know for sure. AOTS isn't enough to convince me that they will.

I say all this because recognizing bias is important. However, people can still give solid reviews and information even if they hold some bias. I don't dislike Jay, Linus, Tek, etc., but I do not take their words as gospel. I compare the information in videos to the information given by forumites on, say, OCN. I look at other sites as well, and try to form an opinion based on those observations prior to purchase.

If what has been reported about the 480 is true, I will more than likely purchase one, but I have to get more information before I do.

Interesting tidbits about the stars near Polaris. I was president of my school's Astronomy Club just under a decade ago, and it's fun to use astronomy to try figure out what AMD's plans are.
Your argument just doesn't really make sense. Tonga looks exactly the same as any other GCN "revision" on AMD's official block diagrams. Pitcairn and Tahiti cores are GCN1 and have the same feature sets. Hawaii and Bonaire are "GCN 2" and share the same new features, Tonga and Fiji are "GCN 3" and have the same new features. The RX 480 has all of the features the "GCN 3" cards have, plus a whole lot more.

There is no evidence at all for the RX480 being a die-shrunk and updated Hawaii. It'd be more accurate to say it's a die shrunk, updated and expanded Tonga, or an updated, shrunk, cut-down Fiji. Neither one of those are really accurate either. Polaris is a huge update to the GCN architecture, while preserving it's key elements and overall layout.

While I hate to use a car analogy, it's like saying that since the 2005 Mustang kind of looks like the 1965 Mustang, it must be more closely related to the 1965 Mustang, than it is the 2004 Mustang.

This card is a winner on my book, 265hevc decoding, good performance for gaming, HDR, hdmi 2 and that price; solid! And to think I almost spend money on a 960 to be able to do hevc decoding for my HTPC

I have high doubts that we will see any IPC improvements. What might improve the performance in DX11 is the increase in the instruction buffer size. So I expect 480X with 2560 SP to perform about the same as 390 clock-for-clock, a bit better when CPU is the bottleneck. Ofc, it will have 10-15% ~20% frequency advantage, which should put it close or above 390X.

$199 confirmed for RX480 4GB and thats it


for the rest - stay tuned redface.gif

Confirmed by Mahigan every time he gets a chance, other than that I haven't seen a confirmation

I think we'll see big ipc improvements but only in older apis. Amd seem to have the same shader cores but improved everything around them ie more of the theoretical max tflops will convert to fps. Its easy to fill a die with shaders, as many as you want and get x theoretical tf, feeding them cores work to do is a completely different story though.
edit what i mean is that its pointless at this stage to suggest performance guesses based on older gcn peformance at the same clock

So I'd like to address this since I can speak to how we have handled this exact thing. Mods, if this is too off-topic please feel free to delete it.

The review site space is in a transitional phase right now. Site impressions are in general falling while new media (ie: social media, YouTube, vine, Twitch, etc.) is taking over which has been a reality we have all struggled to cope with. Some better than others. As a direct result typical "print" publications are fighting for a diminishing pool of advertising money which makes every dollar and impression that much more precious.

This situation has also caused an epic ton of junk "journalism" with sites posting Gawker-like rumor stories aa truth in an effort to drive traffic. Many of the true PRESS remaining have been watching this trend with disgust but folks lap it up like wet sponges. Seeing some of those rumor mongers being treated like royalty at certain manufacturer-sponsored events is infuriating but it also serves notice to some about where success may lie. That's worrying.

It has also led to some publications turning a blind eye to potential bias to insure they receive the latest and greatest sample. A glowing review can be pimped to local PR heads who will then pass it around their company. Without said sampling you lose impressions and money. That's why much of the press were scared crapless after AMD admitted to cherry picking sites for their Nano launch. Whereas these things typically went unsaid in this industry, in that case the threat was direct, in plain writing and would directly impact their ability to meet impression targets if, in the future, they weren't sampled. Hence why in many situations -especially for smaller sites + channels- the threat of withheld samples is potentially more damaging than a lost ad contract.

So how have sites mitigated these risks? I can't speak for everyone but here's what we did:

- Keep advertising negotiations and payment processing transparent to the review staff & editors. Doing otherwise presents a serious conflict of interest.

- Diversify past print-only. YouTube, Vessel, Twitch, etc. all provide additional revenue streams so a site isn't tied at the hip to those key site impression metrics to put bread on the table

- Always, ALWAYS have a back up plan in case a premier product isn't sampled to you.

- Foster good partnerships. Many companies are completely open to criticism provided they aren't blindsided by it. If you trash a product, you better have the reasoning to back it up.


We also have to remember that there is a very distinct difference between "press" and "personalities". There's a journalistic code of ethics that's being increasingly trampled upon these days and you should never turn a blind eye to that.

Hope that helps.

Correct but so was GCN 1.1 to 1.2. These (including GCN 1.3) are simple architectural EVOLUTIONS and are not a completely new architecture. Their respective pipelines remain the same. At its heart Polaris is still GCN 1.x. The basic building blocks are fundamentally strong so there was no need to completely change them.

While I haven't always agreed with your vision of some of the products you've reviewed, i've always found you and the techsite you work for to be one of the most organized, thorough and legitimate website out there today.

The problem that I have are with certain participants who previously worked for e-tailers and developed their relationships with the tech world that way. Now that they've transitioned their careers into tech reviewers, they're more mouthpieces of the companies that supply them with so much excess review items that are just conveniently used in day to day operations. At least with HWC, I know that Sky sells most of his review samples and donates the money to a Canadian charity.

With the amount of reviews and tech sites out there you really do need to comb through them to find unbias and indepth material. Other than benchmarks, im eager to see the RX line up. Thank you for the insight.
