It just makes so much sense to make smaller dies put them on the same substrate connected togheter as 1 GPU, all they need is to make a new communication protocol thats not like crossfire, where the GPU firmware and drivers treat the GPU as 1 single unit, not requiring developers to program for xfire.

GPUs need tons, tons and tons, of memory bandwidth so that is a big problem for any MCM or chiplet design. Might need to go with the EPYC2 I/O die approach for it to work, but with the entire front end of the GPU in that die and all the CUs (or their replacements) in the chiplets.

 

Bandwidth between the die and the chiplets needs to be equally massive as the memory bandwidth though and AMD has nothing even close to what is required. The EPYC2 newer IF is only 100GB/s, which is between 3 to 10 times to little. Maybe the more chiplets the less bandwidth is required to each, I have no idea, but working with the 100GB/s you'd need 10 chiplets for a high end GPU.

 

Multi GPU and MCM in the pure compute world is easy, you actually just treat them as two independent work units and forgo any communication between the dies. Not perfect for every compute workload but applicable to the majority, those that don't fit that need to use Nvidia NVLink or Vega 7nm IF.

So did I, but that was well after launch.

 

I got a R9 290 ~3-4 months after launch when the tri-X came out and then 12 months later again and ran them in X-Fire for a while. Keep in mind that was 300AUD, probs closer to 7-800AUD at launch.

 

the RX590 is mean to be a the same again. Greate deal if you looking at a mid range card on a budget. Are you gaming at 4k? no? it's an option. 1440p also an option, depending on the refresh rate. 1080p, there isn't really a point in going nVidia, unless there is a feature set you want. Just pick your budget and go (which ever team is closest to your budget).

 

Thing is R9 200 series was positioned as higher tier than RX 590 is though. Prices are still high in mid-range specially due to miners effect. And RX is another refresh of the same card that is replacing, yet it's priced higher. 

It can also depend from country to country as far as price cost vs average salaries.

Oh well, at least it's measurably faster than the 580, which we couldn't always say for the 480.

Yeah, my 480 performs identically to a 580 cos it's an aftermarket card with higher clocks .

Correct me if I'm wrong but as far as I know it won't be replacing the RX 580.

 

The 580 and 590 will be sold alongside each other afaik.

Oh they will. RX 480 is already phased out, RX 580 is not that old yet, but all these are the same GPU though. Slight clock increases and that's it. It's not even named RX 680 even. They're just making their mid range GPU bit stronger to keep up with time and stay relevant.

I think you're confused. 

 

The 580 die is physically not the same as a 590 die. They are pin compatible so OEMs can re-use the same coolers and stuff as 580 but they're not the same die.

Also, @The Benjamins I think this chart from Anandtech should be added to the OP to show a kind of best case scenario for RX 590.

It's just tweaked process, die area and transistor density is the same. Even if it's not, it wouldn't mean anything though. Slight increase in performance again with more power draw.

It does. You said that you thought they would discontinue the RX 580 because the RX 590 is now launching. 

 

I'm saying that there's no way in hell that AMD would approve of board partners discontinuing the RX 580 at this stage.

 

It doesn't matter that they are similar products and that the RX 580 probably will cannibalize a lot of RX 590 sales, they are both independent products in a series and the RX 590 is not the successor to the RX 580. The 590 exists to offer vastly superior performance to the GTX 1060 so that it can perform better in all titles. In one or two titles it even beats the GTX 1070. The 480 and 580 are within margin of error of the 1060  in 2018.

 

IF hypothetically AMD discontinued the RX 580 at this point it would: be immediately replaced with the OEM rebadge RX 580X which is identical, would make no sense at all, and cause even worse PR for AMD.

No, I didn't say that they would discontinue it, I was alluding that yet another Polaris refresh will come with a different name and slight boost to stay competitive.

 

Calling it direct replacement or not doesn't matter, it's a slight performance improvement, from a year+ old same GPU that they tweaked, again. It may not be successor as how AMD is marketing it, but it really is though, it should be cheaper and rest of RX 500 series once this launches. $280 for RX 580 is not really attracting that much, specially cause it will cost much more at many places. Really a better buy is Vega now at least where I see how prices for it dropped though.

Again you're confused or deliberately misleading.

 

$280 for an RX 580 is overpriced and unattractive. But $280 for an RX 590 isn't because it's not a 580.

My bad there, I meant Rx 590 not 580 for said price.
