AMD Might Replace RX 500 Cards with RX Vega 28 and 32
There's some new chatter in the channels that AMD will be releasing an RX Vega 32 and 28 to replace the current 500 line. The cards would use the smaller Vega11 GPU.
This chatter is based on some RRA certificate spotting that wccftech noticed, coming from South Korea, where the new cards have been spotted. The names are RX Vega 32 and RX Vega 28, just multiply the numbers by 64 shader procs per cluster and you will notice that the cards have 2048 (Vega11 XT) and 1792 (Vega11 Pro) shader processors per card model.
Here's where the story gets weird, it is stated that the cards would be fitted with an expensive 4GB HBM2 chip. That means a 1024-bit wide memory bus. If correct, the products would battle the field where the GeForce GTX 1060 is active.

Considering how the current Vega cards are memory bandwidth starved due to cutting costs, this would only make sense if they used the same memory configuration for less powerful GPUs that need less bandwidth. Cutting the amount of memory in half seems so weird at this point I find it hard to believe.

Sure, but this is only unofficial info at this point, can't determine their strategy from just that.

Well, let me tell you something, Vega's Memory architecture is very powerful, needless to say. Sure, they are using HBM2 which is expensive but they've introduced a lot of other changes as well. They've basically made it so good, that at most, Vega actually needs 50% of vram compared to previous generations. I am not making this up. Raja Koduri himself said it during some interview. Also, since the bandwidth is so large, memory can be swapped in and out much faster, if needed.
Go home AMD, your drunk. Releasing a mid-range card that doesn't have more than 4gb of ram is nuts. It's going to be gimped like the gtx1060 3gb is.

The bandwidth is not particularly large. Just look at the specs. It would have been huge if they had used more than two stacks, like Nvidia did in their pro card, but undoubtly due to cost issues AMD went for two stacks. It resulted in a bandwidth that is only similar to the original 1080Ti and less than the new 1080Ti version with faster memory.
