New AMD GPU 6000 series - confirmed! Good for mining?

[jmigdlc99]

The new AMD GPU specs are out! Although no mining hashrates yet, seems as usual, AMD cards are cheaper and more efficient.


Radeon RX 6900 XT, available December 8th, MSRP of $999

80 compute units
2015MHz game clock / 2250MHz boost clock
128MB Infinity Cache + 16GB GDDR6
300W TGP

Meant to be as fast an RTX 3090

----

Radeon RX 6800 XT, available November 18th, MSRP of $649

72 compute units

2015MHz game clock / 2250MHz boost clock
128MB Infinity Cache + 16GB GDDR6
300W TGP

Meant to be as fast as an RTX 3080

cant wait to see hashrate of 6800xt and 6900xt

[SalvajeX]

Any educated guesses on the actual hash rates?
the memory and bus have not changed so it'll be interesting to understand how the infinity cash affects it...

If it has no video output that is a huge downside.  Crypto mining becomes unprofitable a your resale value will be almost zero.

[Sebahl]

Of course it has a video output. It is a gaming GPU. The 6800XT will probably the most interesting from a cost/benefit perspective.

Are they making a mining specific GPU like the p106?

Ah, sorry for the confusion, no there are no AMD 'mining cards' announced at this time. I've updated the post title to make it less confusing.

These new AMD GPUS are consumer grade with all the video HDMI / display ports outputs you'd expect to have.

[Metroid]

No way to know, that infinity cache is something to look forward too. What is good about them is all are 16gb gddr, what is bad is price but the gaming performance on their slides justifies it at moment, need to wait reviews if true.

[chinh.daongoc]

They use GD6, which is only half bandwidth compare to GD6X on 3080 3090. Maybe "Infinity cache" could helps in games, but not very useful for memory hunger application like mining ETH.

It's not clear if infinity cache will help compute performance or just CPU to GPU bandwidth which isn't a concern
for mining.

Cache will be interesting for RandomX...this might rival top CPUs for randomx...128mb can feed 64 cores so even if each core can compute less than a CPU you have 4x cores per GPU.

For ETH it comes down to which GDDR6 chips they are using...seems like they are using a 256bit bus so won't be much faster than a 5700 if they are same chips. Bandwidth is about 10% more than 5700 stock settings, so with timings and OC might be able to hit 65-70, and with higher core count id say 70+ is doable at the same power of a 5700.

I bet 5700s will come down to under $300 once these launch though so they will still be better in terms of $/hash.

Not to hijack this thread, but curious if the GD6X suffers the same eth mining problems as GD5X?

[VasilyS]

All cards have memory bandwidth only 512 GB / sec. That's why hashrate on Ethash will be around 64 mh/s (without overclocking). Nvidia with GDDR6X is a winner without any doubts (+30% hashrate on 3080 in comparaison with RX6900XT). Amd doesn't wish to sell their cards to miners. Latest RDNA2 cards are designated for gamers. Mabe RX6700/RX6700XT will be more attractive for miners.

[P00P135]

Maybe if some mining software can take advantage of infinity cache we'll see some good numbers.

[ol92]

Eth mining use random access to a 4G DAG file: the 128MB cache should not be helpfull for ethereum. On the other side, it may help for others algo, such as randomx, provided miners are optimized for the new architecture.

One interesting fact from the specs. - both cards have the same declared total GPU power (300 W). Does this mean that the 6900XT will be more effective? Still, in the official specs. (https://www.amd.com/en/products/specifications/compare/graphics/10516%2C10521%2C10526) recommended PSU for 6900XT is 850 W, and for the 6800XT is 750 W.

[crazydane]

Yes, the 6900XT is 65% more efficient compared to the 6800XT which is about 50% more efficient (both compared against the 5700 XT).

its seems 6800 xt is the sweetspot at good price, 6900xt no sense to buy only 10% more compute with same spec

with new tech hope miner dev can use the advantage of this, surely we wont see anytime soon

need to grab 6800 xt for testing and gaming for moment waiting news from mining progress come up

I guess you are assuming because there no reviews yet.

binned but uses the same process die, all of them use the same process, disabled computing units, all are 16gb.

you pointed out only about performance, but if 6900xt is more efficient it can be worth it... like 1080 vs 1080ti, sometimes the top of the line can be a sweet spot too.

anyway this (if) AMD and NVIDIA new generation of GPUs are around x2 of 5700xt in hashrate performance...this will be good for mining density

it seems AMD will be the one needing an ETH pill this time with this "infinity cache" thing hehe
