[Rumor, Tweaktown] AMD to launch next-gen Navi graphics cards at E3

[Veradun]

It seems strange, shouldn't it be a final cut of Navi 10, aka LE or XL?

 

[Glo.]

I'm confused, I though Navi 12 was a HBM spin of Navi 10 for Apple Macs only?

Looks like not really.

 

[Glo.]

If this GPU really is RX 5600 XT, and is based on Navi 12, and it really is released at the end of this year, or beginning of next, it puts a little perspective into rushed Navi 12 support for Linux 5.4 Kernel.

Kernel 5.5 Will not be released until end of January/beginning of February.

A 32cu 192bit Navi 12 would hit the spot where it's realistically out of reach of any TU 116 variant performance-wise while being too small for any TU 106 die to compete in a cost-effective manner.

If 7nm process yields can't accommodate 300+mm die sizes there are much worse places to put R&D money than Navi 12.

 

[Glo.]

And it will be interesting to observe how the amount of CU's per shader engine affects the performance of the RDNA GPUs.

I would not be surprised, looking at RX 5500 if lesser ALUs per Shader Engine count, the better perfomance scaling.

32 CU already require two shader engines. Which makes the CU/Shader Engine count to 16. Navi 10 has 20, and Navi 14 - 24 CU's per Shader Engine.

I got the same card and I find it has an excellent value.

Bonus: you can register it with XFX for a 3y warranty -> http://support.xfxproducts.com/Account/Login.aspx

Thanks for the heads up. I will definitely be taking advantage of that.

Now I’m worried my daughter will see the new card and demand a new card of her own rather than the hand-me-down RX 570 I’m giving her. Gonna have to do this upgrade on the sly.

- Make sure she doesn't try anything on the sly either!

When I was much younger, a friend of mine picked up a GTX 5700 and his dad bought a GTX 5900 just so he could have the more powerful computer (he didn't game or use his computer for any sort of productivity stuff). When his old man was out, he swapped the two GPUs and got an upgrade with no one being the wiser.

Hope we don't see you back here complaining that your new card isn't any faster than your old RX 570 in a few weeks

 

[Tuna-Fish]

Now I know each card can have an optimised thermal solution, but that sort of data correlation is just plain ridiculous - are there any other reviews that sport similar findings?

It's not an accident. The current nVidia turbo solution turboes the cards until the Tmax is reached, and for their current card lineup, that is 68 degrees.

The Nav12 part is speculation, but 6GB and model SKU are real. I have a piece that didn't go live (yet), because I'm waiting for confirmation.
You were not supposed to find this ;p (kidding).

AMD Radeon RX 5500 XT launches next week, Radeon RX 5600 XT in January? - VideoCardz.com

AMD Radeon is making a push in a mid-range segment. Radeon RX 5600 XT and RX 5500 XT Radeon RX 5600 XT This is the first post where we mention the Radeon RX 5600 series. We have confirmed that at least two board partners are working on Radeon RX 5600 XT. The new Radeon would […]

12th December is next week.

If true that would be a little awkward. The 5500 can have 8GB vram while the 5600 only has 6.

Couldn't the 5600 get 12? xD

Think about it, a somewhat cheap futureproof 1080p card with 12GBs!

While I agree, it's still awkward, just for the 5700 XT...

The 192-bit bus selection is weird. I dont belive AMD has EVER used this configuration before, even on ATI years.

The 192-bit bus selection is weird. I dont belive AMD has EVER used this configuration before, even on ATI years.

I don't think they have either now that I think about it. That does make the information a little suspect for that reason, but that doesn't make it wrong. Was there ever any particular reason that AMD/ATI never used a 192-bit bus in the past? I can think of several cards that certainly would have benefited from the additional bandwidth. Were there some kind of architectural constraints that previously prohibited them from going this route that RDNA has removed?

 

[GodisanAtheist]

The 7900 series used an off-kilter 384-bit memory bus with 3GB of memory, so its not like AMD is married to a 64/128/256/512-bit bus width.

If memory bandwidth is important to product segmentation then AMD will use a 192 bit bus if they have to.

Edit: Its worth noting that AMD used the 384-bit bus width on the Tahiti chips (HD 7900/ HD 280 series), then never used them again anywhere else, so there really is a first and possibly last time for everything

 

[Veradun]

They used 384b and 512b tho, since the latter has been shrinked to its half nowadays it seems natural to also shrink the former

 

[lifeblood]

According to the Anadtech review the RX 5300M uses a 96-bit bus with 3GB of vram. That's an equally weird bus/vram size. I assume the chip is a standard Navi 14 that is 128-bit capable but they just didn't use the entire bus.

Are we sure the RX 5600 and Navi 12 are one and the same? Like the 5300M they could be harvesting Navi 10 chips that didn't pass muster as 5700 chips and using them as 5600 chips.

 

[Glo.]

Why only RX 5700, 5500 and 5300 series be RDNA1?

Wouldn't RX 5600 XT also be RDNA1 based?

Or it is RDNA2.0 and based on Navi 12?

 

[Ranulf]

Definately glad I decided to wait out till RDNA 2.0/Navi gen 1.5 or 2 or whatever it will be this year or next. Same ol situation as Polaris 480/580 and somewhat the R9 290 vs 390.

 

[GodisanAtheist]

I suspect RDNA 1.0 will get refreshed when RDNA 2.0 comes out, and the two archs will occupy the lower and upper half of the market simultaneously.

I suspect RDNA 1.0 will get refreshed when RDNA 2.0 comes out, and the two archs will occupy the lower and upper half of the market simultaneously.

I wonder if that was the original plan. Let’s be honest, AMD’s GPU division has been marking time since original Polaris. AMD focused (ie, spent all available R&D money) on ZEN while leaving the GPU division on financial life support. The 500 series was just a zero effort refresh while the RX 590 was a zero effort refresh on a slightly tweaked process. Vega and Radeon VII were an underfunded halfhearted effort for the sole purpose of crying out “We’re not dead yet!”. I suspect Navi has always been the real comeback effort.

What I’m curious about is whether RDNA v1 is just an intermediate step, another “We’re not dead yet!” moment until they can get RDNA v2 out the door, or if v1 was really part of the original plan. Was v1 the end-all-be-all or did they originally plan on v1 being the low to mid architecture and v2 being the mid to high architecture? How did Nvidia’s Ray Tracing effect their plans?

In the end it doesn’t matter, obviously RDNA v1 is a good architecture which, unlike Vega, very definitely is a step forward in performance per watt and in raw performance as well.

 

[Dribble]

I suspect they originally planned on RDNA v1 being the console architecture, but then ray tracing threw a spanner in the works as the console makers demanded in their gpus. At which point there has been a rush to add it onto RDNA.
