before paying the same or more for a aftermarket 6800

Anyway:

I found this 6900 xt at around 1000$ ...I pay only shipping charges.

open box... I read used...

Yes it is used.The new card in retail is much more.I want to buy in the 3080 / 6800 teritory of performance but don't want to pay retail prices.Seems AMD have the most devalued card in the "used" market.

[pax]

yea but used in this market can easily mean a burnt out mining card.

I won't deny that there might be a chance ... The price for a new 6900xt is 1800$.Don't sit very well with my confort zone.
I wished to actually feel that i've ugraded so i wanted something in the 3080 / 6900 performance teritory.Now i realized that a 3070 may have better RTX performance than the 6900xt.The problem is 1440p with RTX is too much for 8gb.The alternative would be to buy a 2080ti that have 11gb but again is only second hand.
The new 3070ti with 16gb would be a sweet but if it will 1800$ .... Meh

RT performance with nV is much higher than AMD. 12GB is more than enough for 1440p gaming.

AMD confirms RDNA 3 GPUs this year and is spending big to 'to satisfy the demand out there'

The company has just turned in its 2021 financials, listing a 68% rise in overall revenue compared to 2020, which includes double-digit percentage growth in terms of both GPUs shipped and revenue

"Demand for our product is very strong," says Dr. Su in the recent earnings call, "and we look forward to another year of significant growth and share gains as we ramp our current products and launch our next wave of Zen 4 CPUs and RDNA 3 GPUs. We have also made significant investments to secure the capacity needed to support our growth in 2022 and beyond."

I am spending big on my patience

The increased capacity is something they say just about every generation of late... and they dont say by how much they could squeeze out of TSMC vs its other customers.

they are TSMC's Third Largest Customer after Apple and MediaTek
and AMD is expected to move up to #2

NV is 6th and Intel last

[pax]

Well one way to increase capacity is simply the move to a smaller node where you get more cpus out of every 300mm wafer vs 7nm. But then they usually also increase the transistor count of new cpus so its not a straight up increase from the node change only.

I can see more production via more fabs at some point a couple years from now but it takes a long time to get new fabs working.

well the game consoles will stay on 7nm and RDNA 3 will be on 5nm that should help a lot

[Gandalfthewhite]

yeah the bigger help will be node separation of product stacks. as the PC side moves to 6 and 5 nm nodes and the consoles stay on 7nm for now. Also server CPUs typically transition after consumer at this point so that will buy some extra consumer product capacity for 3-6 months.

[pax]

Ya most recent news is the navi3 will be 6 nm in the control chip and 5nm on the gpu dies making more room on the 5nm node for gpus. Should help with availability.

AMD Radeon RX 7000 'RDNA 3' Graphics Cards To Feature 5nm & 6nm GPU Process In MCM & Monolithic Designs

The information was posted under the LinkedIn of AMD's Infinity Data Fabric Silicon design engineer, Brian Walters, who has worked on various projects including the next-generation graphics lineup which includes RDNA 3 powered Navi 31, Navi 32, Navi 33, & Instinct MI30

[bill dennison]

and as much as chiplets helped CPU yields

RDNA 3 should benefit from chiplets yields near as much

AMD Radeon RX 7600 XT will be faster than RX 6900 XT, will be the first RX 7000 GPU to be launched [Rumor]

will it be priced like a low end or priced like a high end?

low end of 799

who knows any more with the high end selling for 2k

Right, it's all up in the air, AIBs will charge as much as they can.

[pax]

One site said vendors might give up on MSRP entirely next gen... Can you imagine buying a lowly 128 bit mem bus vidcard for what was high end price just a couple years ago...

Thx for the news ... Got a smile on my face
I think AMD thought that the market don't need those very high end parts so quickly.Who had big money already have a very high end part already.
The rest of the population on the other hand either bought a very underperforming gpu at a very high price or they couldn't find it anyway.
Assuming that the 7600 series will be priced at around 6600 level then you will have a 6800xt performance at half the price.Huge jump but the catch is the MSRP of the 6800 xt (600 $) is the price for the current 6600 xt.It will feel like you will get a 6800xt at MSRP ... finally
I smell backlash ... People who got a 6800 xt overpriced and it will be halved in value in 2 years will be very pissed.Let alone 6900xt ....

[Gandalfthewhite]

no we are not going down the crazy town hype train. I do not believe the 7600xt will be a 6900xt performance let's not do this hype it up so high when it doesnt meet the hype it is a massive disappointment.

There is three reasons that may not be another hype:
1. The POS in summer will make miners dump gpu's in the second hand market.
2. To combat first option both AMD/Nvidia will need to bring very very intersting products otherwise we will buy from the crashed second hand market.
3. i do feel that AMD releasing 7600 cards series after the POS in Q3 may be intentionally to make people avoid miners gpus and buy new ones.

has anything historically had a next gen jump at the level before?

It is a bit tough to believe (not impossible mind you) considering a 6600XT is only a little bit faster than a 5700XT......

If we base it on the RDNA2 upgrade, then a 7600XT should be similar or better than a 6700XT....which would be a far cry from a 6900XT.

[pax]

5120 shaders on a 128 bit bus will be slower than a 6900xt but RT might be faster imo.

back in like the 9500 era days maybe... but it was a radical shift in design.


I would rather see a a medium (30-40% over 6900xt) bump on the 7900xt well keeping thermals power draw in check in the shift to MCM then bust out to 400+ watt monster that needs to be watercooled just to handle it. which is what I am scared we are going to see.

isn't MCM Chiplets in a GPU a radical shift in design ?

The Radeon RX 7900 XT will pack up to a total of 15,360 shaders across 60 Work Group Processors (WGPs) paired with 16GB of GDDR6 memory across a 256-but bus. The L3 “Infinity” Cache will be increased to 256MB, 3D stacked upon the primary compute die. The GPU core will run at around 2.5GHz, same as Navi 21 which is a bit surprising if it’s fabbed on TSMC’s N5 node (might be N6 to improve supply). Overall, Navi 31 should easily be 2.2-2.5x faster than its predecessor, with the RX 7800 XT beating the RX 6800 XT by up to 50%.

https://www.hardwaretimes.com/amd-ra...hiplet-design/


unless all the specs we have been getting for over a year plus are all BS it better be 85% faster or they should have released a correction a long time ago

but i do think it maybe power hungry but not as bad as high lovelace
at (30-40% over 6900xt) lovelace will kill it as that is only 15 to 25% over a top end 3090
as high as they say NV is taking the watts

[pax]

Theres no way you'll get just 40% above a 6900xt with 3 times the shaders.

One guy said theres a reason they called the 6000's navi2x it was 2x navi 1 and navi3x is thus 3x navi 2.

That shader count seems to make sense tho I suspect its gonna be used to improve RT so it might be 3x RT and maybe not quite that in raster. Maybe due to mem bottleneck. Hard to see a 256 bit bus feed 3x the shaders in raster at 2.5 to 3ghz.
