It's also $1000 USD and the benchmarks AMD released today assumed you're using an AMD 5000 series CPU and new motherboard. I think the 6800 is going to be the good AMD card for mining as of right now. |

Why does everyone assume these ridiculous numbers for 6000 series GPUs? Did you see the specs? They all have GDDR6 with 256 bit bus, 512 GB/s bandwidth only. They will do ~60 MH/s at best in stock, maybe up to 70 MH/s with memory overclock. |

Isn't it possible the Infinity Cache will improve ETH performance? Perhaps once tweaks are done in the mining software?

If it was entirely VRAM based then an ASIC would simple need HBM and a cheap FPGA or CPU to mine beyond that capable by a video card. The cores have to actually calculate the solutions and the RAM is needed to index that table. Clearly the core count is significantly higher because they were able to increase the efficiency even on the same node, so more of that 16GB of memory will be utilized. You could pair a RX460 with HBM memory and map a large bus to the memory it would still crawl. You need all parts running for ETH (even though everybody always parrots that core is irrelevant). |

ETHash requires 8192 bytes accessed in VRAM per hash, with 512 GB/s bandwidth it's impossible to have more than 67.1 MH/s, no matter what GPU cores can do. Infinity cache can't help when 4 GB of memory is accessed randomly. FPGAs with HBM exist, they have similar bandwidth and hashrates at much lower power consumption (51 MH/s @ 70 watts). |

I'm on a phone right now so I'll take your word for the napkin math. What was the theoretical maximum for Radeon 7 cards if strictly going by memory bandwidth? If it is indeed that close to the bandwidth maximum threshold, then perhaps AMD did not want the cards going to miners. Maybe that was a more of a reason for going GDDR6 instead of HBM2 cost factors. Yields for GDDR6 and GDDR6x have been pretty good from Samsung as it's pretty mature at this point (at least 16Gb). |

Radeon 7 has 1 TB/s bandwidth with theoretical limit of ~134 MH/s, but they don't have enough GPU core power to achieve that. RX 6000 series will have another problem in mining - too much core power vs too little bandwidth.
Edit: but if we don't limit ourselves to only ETHash performance, some other algorithms might get a very nice boost from 128 MB cache. ETHash will just be far from the best option for RX 6000.

If you were to go back in the thread you could read that I said if with much lower numbers then the one above. Just about the numbers you mention. Personally I would love it to be that the 6800xt does 65 at 140 watts for simple miner stats since my power color 5700xt do 51 at 104 watts for simple miner stats If it is the case that the lessor if of 65/140 is true I am just fine with the power color cards If your 70 mh is correct then the card is expensive as 650 for 70. 6800xt. is 9.28 a mh vs 419 for 51 5700xt power color with a bios switch. 8.21 an mh |

Infinity Cache only makes the claimed performance improvements when you pair it with a AMD 5000-series CPU and the software/game is designed to utilize Smart Memory Access |

realistically, if there isnt a significant improvement over the 5600/5700/xts, the blockchain versions of 5700s could be very attractive. Most stable, lowest power polaris has by far been the nitro mining versions.

nitro are premium and have historically been good. I heard good things about them. I could not get a good price, on gaming nitro's. I did get some good deals on the power color red dragons. very happy with them. I kind of want more of the PowerColor Red Dragons |

I'm getting @59 mh eth at @108 watts from the wall for the card (Kill a watt meter reading) |

I'm getting @59 mh eth at @108 watts from the wall for the card (Kill a watt meter reading) Not quite sure how you are getting @108 from the wall. but that is better then the 5700xt which will do 52 at 103 which is simple's reading so that is 121 at the wall, if you get a good one. now one of them costs 500 the other costs 420. So that is very close in quality to a 5700xt power color red dragon it would take a while but 7mh is 7 x 2.5 cents or 17.5 cents a day and maybe 2.5 cent in power so for mining eth 20 cents a day better and that is 400 days to make up the price difference. since warranty is for 1000 days. you can say it is a tiny bit better. the 3080 looks to be a clear cut above the 3070. but they run 700. so all in all a good PowerColor red dragon at 419/420 usd is competitive, but a little lesser. |

I have 50% set in afterburner with mem +1000 and gpu stock. I'm also running a super flower titanium 750 watt psu. Super flower are the same psu as evga. this is my first card. putting the second card in the gf computer when she goes to sleep tonight. |

If the 3070 is almost the same on a hash/$ ratings as a 6xxx card then I would go with the nVidia simply because their stream encoder is always worth it for resale value down the line and I assume their DLSS will be a little better than AMD's version. If you're going for maximum hash today without regard for resale then the older AMD cards seem to be best bang. Looks like the new gen is great for gamers and meh for miners - at least until tweaks have matured in a couple months.

I will keep my eyes out for a 3080. And hope for price drop on the 5700xt red dragons 🐉 |

I will keep my eyes out for a 3080. I am also. I'm at peak power threshold for my place. I've popped the main circuit breaker 3 times. I have to retire some older gpu and bring in more efficient gpus. I've retired all my 4xx/5xx and 1060 cards. next on the chopping block are some 1070. I've also been switching to more efficient psu (only buying titanium now) |
