AMD Reportedly Readying RX 6900 XTX, Bringing the Battle to NVIDIA RTX 3090

Who actually cares about RayTracing? If it's not PathTraced entirely, it can't be really spotted. Unless it's like a very slow paced game where You have time to look around and "smell the roses".
I played Raytracing turned on in CyberPunk, Metro Enhanced version... wouldn't care less about RT. Have RTX2080S.

LOL, fully path traced for what? that would just throw away of 20 years of progress in rasterization.
DXR is the best of both world, use rasterization and Ray Trace where they are strongest (meaning Global Illumination, Reflections, Lightning and Shadows are best ray traced, the rest are rasterized).

if you didn't care about RT, why would you play Metro Exodus EE, that game requires an RT capable GPU to even run you know.

Not caring about ray tracing is actually quite logical.

There isn’t a card on the market that can handle 60 FPS solid max setting with full ray tracing. Right now it’s just there, without hardware capable of utilizing it to its potential.

There is no 18Gbps GDDR6 by spec.
Link in the article. 1-3% faster than FE, gaming power consumption +36W (~10%) compared to same 3090 FE.

Meaning there is no public 18Gbps documentation. This does not mean that it does not exist. Anandtech reported production in 2018. But keep putting your faith in manufacturer updating their website. Im sure half the stuff Buildzoid covers does also not exist because there is no public datasheet for it.

Let the battle of the 6900 XTX and RTX 3090 Super begin!

Or not. Whatever. Both will just be horrifically overpriced GPUs that scalpers will have wet dreams about.

 

[Operandi]

RTX 3090 vs 6900 XTX: "when an unstoppable force that ppl swear exists, meets an unmovable object that your friend's buddy told you about".

I played the original one and wanted to see if Raytraced brought anything extra to table- it didn't.
Answer to your question: I tried to see if that EE makes me care more - it didn't!

We have established that updating an RX6900XT with newer chip (XTXH) with that AMD "ultimate" liquid cooled RX6900XT bios (18gbps mem), that should work.
But will that LC bios work on those regular RX6900XT's?

 

[Ravenas]

everyone with a existing XTXH card can get this LC Bios on their cards and have the 18Gbps memory (BE AWARE OF THE RISK)!

Just compare the LC Bios Memory to the regular XTXH Bios Memory, they are the SAME Number!

XTXH
AMD LC


Here is a Screenshot of my card running the LC Bios with up to 2370Mhz Speed on the Memory, with the Stock bios i could only get 2160Mhz max.

Which XTXH card are you using?

 

[dicktracy]

Still slow with mediocre FSR and Raytracing. rather buy slow consoles.

I owned them both great cards.

And back on those days high-end cost you $500.

Hi,
Last I saw at micro center powercolor 6900xt was like 2400.us+- so yeah just a tad insanely priced lol

Samsung begins production of 18Gbps GDDR6 memory:

Samsung Begins Mass Production Of 18 Gbps 16-Gigabit GDDR6 Memory - PC Perspective

Samsung Begins Mass Production Of 18 Gbps 16-Gigabit GDDR6 Memory Samsung is now mass producing new higher density GDDR6 memory built on its 10nm-class

pcper.com

There is no 18Gbps Memory, the XTXH LC uses the same memory chips as on my OCF and i just flashed the LC bios when it was added to the VGA Bios Database and got the same 18Gbps to work. when you compare the bioses than you will see, that AMD just raised the Mem voltage from 1.35 to 1.4 Volts and the Memsoc from 850 to 900 MV.

TPU BIOS Link

See above. Samsung does make it.

Same. Those 6900 have been sitting on shelf since forever at local micro center too. Plenty of stock of AMD GPUs----at insane price. So naturally nobody wants them

Hi,
Think couple weekends ago they dropped the price 200.us and a lot were gone at Houston store.

The 6900XT LC with 18Gbps has already been reviewed by PCgameshardware, TL;DR:
_Use 350W stock, same as 3090 FE
_Beat 3090 at 1080p by 4%, tie at 1440p
_Lose to 3090 by 2% at 3440x1440 and 5% at 4K

I see. Great 1080p card I guess, then.

'Using where it is best'... in fact DXR is just the API, its devs that make it tick...

This goes back to the eternal development hell story and DirectX is not exactly known for top efficiency that way. Its a one size fits all API and its built that way, still. If you don't implement the shortcuts yourself, you have a slow piece of shit. Case in point: the actual practice since DirectX exists. Its a fine API, but don't overestimate it. Its good there is one that can cater to all things in one package. But that is what it is, not a single drop more. Its the hardware that makes the FPS appear, and the development work that determines what sort of effect you're getting presented and how much FPS it kills.

As for those four 'best being traced'... you say so, but honestly, I have yet to see any examples of it being objectively better, because its never more efficient. And on top of that I am not any more or less 'immersed' with a traced shadow or a good old shadowmap, be it for global or local shadows or lighting. In fact, many custom built effects that are tweaked to the setting work out quite a lot better for a lot less horsepower. They take work, yes, but so does anything that wants to look special. Meanwhile, Metro Exodus is full of locations that are either too dark or too bright or just not pleasant to look at.

 

[Viilutaja]

In EU there were plenty of RX 6900XT's in ballpark of 1400usd (AIB models) to 1700usd. And those special XTXH models were around 1900 usd.

Not enough to report you once again for your useless fanboy remarks, in this case you just dont make any sense.
The second fastest card overall and you call it "still slow" ? and then you tell people to buy "slow" console instead.....are you ok man? like mentally?

The interesting bit is that these early announcements back in 2018 are it. No cards have used 18Gbps GDDR6 and even 16Gbps has been used only in this last generation.

Samsung lists 12, 14 and 16Gbps GDDR6:

GDDR6 | DRAM | Samsung Semiconductor Global

Meet upgraded GDDR6's industry's fastest speed, greater power efficiency, and incredible versatility, with low voltage for high-bandwidth, high-computing tasks.

Edit:
Actually, it does look like SK Hynix is sampling 16, 18 and 20Gbps GDDR6. Mass producing only 12 and 14 Gbps GDDR6.

Yes Samsung does no doubt about that but AMD is not using it.

_Lose to all NVidia cards by 100% for Iray rendering.
Its too bad their cards can't be used for this, otherwise I would consider having a render farm built with them whenever supply/prices become more reasonable.

I would load the BIOS to my current cards to test for 18gbps throughput, but I don't have copies of their BIOS for my cards.

Nvidia just sold 17,000 founders edition cards through Bestbuy with an in-store only event; they opened the floodgates on Thursday morning (7:30am for me) with ~100 cards at select stores, and were out of stock by the weekend. My store had 30 people lined up at 8:00pm the night before, trying to get their hands on anything. So when faced with a limited amount of wafer supply, what does AMD do? Do they make bread for those who need to upgrade?

No.

They make cake for those who still have money to burn.

Even if these chips were coming from higher binned preexisting silicon rather than built with new allocation, the optics of this rumor are horrible.

You're talking about people with money to spend on high graphics card, and then claiming AMD is screwing the consumer by selling high end graphics cards. Are you focusing on the correct market segment?

Why does AMD have to cave on pricing because Nvidia cards are selling or are unavailable?

wouldn't care less about RT. Have RTX2080S.

Well, these statements all seem like personal truths rather than speaking for everyone. We may be a minority, but there are quite a few of us that enable and enjoy RT effects.

Can it even bee seen? I mean when ATi had superior AA and AF it was extremely noticeable.
