AMD Readies Radeon RX 500X Series Graphics Cards

AMD is giving final touches to the new Radeon RX 500X-series graphics cards. Product page placeholders for RX 580X, RX 570X, RX 560X, and RX 550X surfaced on AMD website. The specifications tabs on these pages are blank, so there's no official information on what the "X" denotes. It's curious to see AMD give the extension to even lower-end SKUs such as the RX 560 and RX 550.

The company has, in the past, come up with extensions such as "D" to denote OEM-specific SKUs with different specifications than the retail-channel (AIB) products. Going by the convention of "X" denoting higher performance on certain AMD Ryzen processor SKUs, the RX 500X series could have one of several improvements - a new silicon fabrication process facilitating a clock-speed bump, or faster memory, or even some speed boosting feature similar to Ryzen XFR (extended frequency range). We'll know soon enough.

I assume these are TSMC or Global Foundries 12nm?

Does it matter? We game at 1440p +, I doubt any of these cards are meant for us, as before AMD can only ask for 1080p market. Unless you like mediocre frames in high rez high refresh gaming of course.

Polaris is rather memory bandwidth starved, higher clock rate won't improve performance much unless they put some higher speed VRAM chips.

Yes. Not everyone is a elite member of the master race like yourself.

It really depends if AMD was able to stick better memory compression on these, which is possible without having to change much hardware wise. It wouldn't be the first time AMD improved memory compression in the same generation like they did with Tonga. It's also entirely possible to use higher speed GDDR5 as well.

"How about we make Polaris rebrands again?"

I certainly hope that, at least, they give those new cards more memory bandwidth and a higher number of CUs... and I also hope for miners to not get those cards, nor raise their prices sky-high.

It does, I know a lot of people who won't buy a new screen to replace their current 1080p or 768p displays, as it is enough for them or don't feel comfortable with larger screens (and/or don't want to deal with scaling and HiDPI). They'd rather get a new card.

That may work, but I'd still prefer that AMD gave the new cards a higher bandwidth than their predecessors. The RX 580 tops out at 256 GB/s, but the R9 390X reached 384 GB/s, using GDDR5. So, it shouldn't be impossible.

i dont think the 580X will be a rebrand... im thinking its going to be a 40CU variant vs 36... the reasons i say this is because XBOX uses this new 40CU chip from amd already; 2560 shaders vs 2304. (its still polaris)

i also think the 550X will have 640 shaders

Here's hoping they put GDDR5X on the 580X and 570X.

That would be good too.

I want a good but cheap AMD GFX.
A 580 does 1440ish... Here's to hoping the 580x does 1440 woooo.

i loved when AMD came back and smashed Nvidia with the 7970, and continued to rival in gaming and smash Nvidia like nothing in Folding and folding related computing... for the HD 7970 vs GTX 680

Doesn't matter what they do if you can't buy one at reasonable price, but until this mining nonsense cools down a bit on the lower end cards I don't see that happening. AMD defiantly has issues on the memory side of things in terms of bandwidth due to their compression and/or bus widths and VRAM choices. They either have to address that or carve out another niche feature like real time ray tracing effects that are optimal for their hardware. If you can't beat them come up with a selling point like Physx.

I am more curious if these are the parts we saw in the drivers with HBM and a polaris die.

You're talking about it like the HD 7970 ended GTX 680. That's a nice alternate universe fantasy.

when it came to gaming they rivaled.. i said this... but when people were folding they didnt think twice...

also dont forget it took nvidia 3 months to release 680 after HD 7970... so.. yeah..

That seems unlikely though, no? If they were really going to Vega the whole line, why wouldn't they brand them as Vega?

Maybe to keep the familiar face? Fury's didn't sell for shit, but the 390/390X did. The 580 already has gobs of brand recognition a 40CU 8GB HBM2 based one would be pretty stout, it would likely rival a 1070Ti.

Yeah, but R9 390X had 512bit wide memory bus. RX 580 only has 256bit. That Hawaii chip was pure brute force.

I don't think there is anything to see. These pages look like a result of a website fuzzy matching feature and not real product pages.

Example proof:

Replace:
https://products.amd.com/en-us/search/desktop-graphics/radeon -rx-series/radeon -rx-500x-series/Radeon -RX-560x/82

with (I removed the Xs):
https://products.amd.com/en-us/search/desktop-graphics/radeon -rx-series/radeon -rx-500-series/Radeon -RX-560/82

You get the exact same page. The 82 (the ID) is the important number.

You can even do this:

https://products.amd.com/en-us/search/desktop-graphics/nvidia-1100-series/nvidia-1180-ti/82

;)

Additionally, all of these published numbers have IDs lower than 94, which belongs to the 14 CU RX 560:

https://products.amd.com/en-us/search/Desktop-Graphics/Radeon™-RX-Series/Radeon™-RX-500-Series/Radeon™-RX-560/94

And we know that this card page appeared in December 2017 when that RX 560 controversy surfaced: https://www.techpowerup.com/239421/amd-officially-but-silently-downgrades-radeon-rx-560-with-an-896-sp-variant.

The vast majority of gamers are on 1080p.
According to steam hardware survey 1440p is at about 3.5%, FHD at 72%.

If they will make so many different variants it will be impossible to find game perfectly for your pc configuration, also Radeon setting not always turns on for all games anti-aliasing, and mess whit previous driver from 2013 for HD 4000 cards make error43.

lol i know right, currently i have a 1080P, 1440P, and 2160P monitor, ill use 1440P in games the GTX 1080 Ti cant handle in 4k, i only play max settings and theres 3 that kills my 1080 ti.

IMO;

12nm refresh, increased ceiling goes to clocks and some higher clocked (doubt we'll see GDDR5X though) memory to go with.

We *may* also see rationalisation in the lower product stacks, AMD doesn't have a direct competitor against the 1050 Ti for example, and even the 1050 is a little touch and go with this big jump between the 560 and 570. IMO, we may see the 550 increase to 560 spec, and the 560 gain a few CU's.

if the 580X obtains the 40CU variant chip it might have 384bit GDDR5 memory

but then again.. i doubt it because that would certainly merit another generation name, like 680..
