AMD RX 5700 Navi New arch

Recommended Posts

Posted · Original PosterOP

AMD has launched their new arch, past GCN which was originally introduced with the 7970 (Tahiti IIRC).

The naming scheme will be RX 5000, or an extra 0 past RX 500.

Quote

1.25x peformance per clock

(source: Lisa Su)

 

 

RX 5700 (midrange?) beats RX 2070 in strange brigade by 10%, so similar to V64. Much smaller die, no HBM, so GDDR6.

 

My expected price is ~400-450$. Keep in mind AMD's profit margins are really low, 1/6 of intel, 1/3 of Nvidia)

 

More news at E3 2019, June 10.

 

Edit: I'll be sleeping now, 11:10. GN everyone

 

Edit 2: 180W lower clocked SKU and 225W SKU (regular), and 150W SKU

https://wccftech.com/amd-radeon-rx-5000-navi-gpu-7nm-asrock-two-variants-report/

Could this be a RX 5700 XT (225) Pro (180)?

or perhaps a mITX version like V56

 

 

RX 5700 XT is ~10% better than RTX 2070, 450$

RX 5700 is ~15% better than RTX 2060, 380??

 

oh and R5 3600(X), 200/250$

Nobody saw THAT coming!

 

Neither GCN - as many people claimed.

Neither named as any one said it would...


Just take the RX 570 and add another zero, call it a day.

And troll the Competition, who wanted a trademark on the Numbers :D

It kind of has me worried that they used Strange Brigade for their benchmarks for it to be honest. It's a new architecture, but I don't see it as unlikely that it'd take some level of design queues from what they already have? Also notable is that they did 5700 vs 2070 instead of 5800 vs 2080, because in their CES keynote they were showing the Radeon VII having closer to 20% better performance than the 2080 whereas the 5700 only has 10% better performance than the 2070. So maybe the 5800 performs worse than the Radeon VII? Or maybe the Radeon VII's running on Vega made it more capable in that game than the 5800 in spite of its likely being based off of it (And GCN), and the 5800 outperforms it in other titles? But does that mean that in other Vulkan titles AMD's old hardware will beat their new hardware? It'll be good to have the benchmarks in so we can get some decent clarification on this stuff, because it all seems rather odd. I have higher hopes for the CPU than GPU side of things either way.


"uhhhhhhhhhh yeah id go with the 2600 its a good value for the money"

i think that was actually off an earlier AMD presentation during the Zen 1/+ era o_o RDNA seems recent

Yeah, the game heavily favored Radeon cards.

Regarding the architecture.

 

On the one hand 1.25 times higher IPC for Navi compared to Vega is seriously impressive. That means that a hypothetical big Navi card with 60 CUs at Radeon 7 clocks and memory bandwidth levels will actually be a RTX 2080 ti competitor. This is without even considering the possibility of additional CUs...

 

On the other hand strange brigade is a cherry picked benchmark. Look at the numbers

https://www.guru3d.com/articles-pages/amd-radeon-vii-16-gb-review,15.html

The Vega 64 is already beating the RTX 2070  in this game. So this particular new Navi part looks to be no faster than the Vega 64.

 

Putting all the above data together what we can gather from this is that the new architecture is more efficient than Vega in geometry performance and work done per clock cycle. But AMD has not yet been able to turn it into ground breaking SKUs. That could be because they are not hitting the clockspeeds they want, or that they are still have a way to go with driver optimization because this is such a new architecture.

Yep, based on this the new Navi card has Vega 64 performance, nothing more.

Whilst i suspect your probably right, without knowing exactly how new RDNA is, (it could be a GCN refresh rebrand), thats a dangerous assumption to make. We saw with Turing that NVIDIA deliberately targeted performance in area's AMD is normally strong in.If it's more than just a rebranding AMD may well have done the same. If so that would have major implications on things. I agree strange Brigade was probably chosen because it's a favourable benchmark, but it would be dangerous to assume that AMD's weakest area's are the same.

 

Anyway i think it's almost my bedtime so i'll have to pick this up in the morning.

There is no way the architecture is a rebrand. From what we have heard they had loads of engineers working on this for years, it's not a rebrand.

 

However it may inherit a lot of things from GCN. I don't think they would have gone in and redesigned every single thing, they would have focused on areas identified as bottlenecks and just tweaked the rest.

SOooo What I am getting here is.... don't preorder cause even then it doesn't seem like the card we all want 

is it even preorderable now ._.

To summarize

-RDNA replaces GCN as the new longterm macro-architecture 

-RDNA has allowed 25% better IPC and 1.5 times better performance per watt.

-PCIE 4.0 supported

-Higher clock speeds than GCN

-Compute Units have been redesigned, and the 4096 SP limit is gone

-Navi is merely the first micro-architecture under RDNA.

-Navi is a gamer focused part

Given how much were told about RDNA (almost nothing) I don't feel comfortable making any conclusions about what RDNA is.

What's weird is that they just keep tossing out the model numbers with no consistency. It's why we were all WTF when NVIDIA launched GTX 1600 that doesn't fit anywhere naming scheme wise.

 

Why hasn't AMD started with AMD Radeon RX 1700 ? And then RX 2700 and RX 3700 etc. It's how it was done for decades now. Coz if you plan on just throwing out random model numbers, why not stick with names? Radeon RX Navi ? What's wrong with that? Sounds cool and is about as helpful as throwing RX 5700 out of the blue.

Just a wild guess, but maybe AMD didn't want to use names/numbers that remind people of Gen1 Ryzen for their new graphics cards.  The added 0 also suggests a large increase in performance, which is probably what the marketing people were aiming for.
Personally, I don't care too much about the name on the label, I care about the product itself.

Can't wait to see more in-depth info regarding RDNA, what it has to offer and what are its benefits. No mention of Ray Tracing, so I'm wondering what do they have up their sleeves with it considering they have long term plans for it.

I think they won't talk about Ray Tracing until Navi 20. Because they don't have it for now, so making a big deal about it just diverts attention to Nvidia RTX products.
