Bitmain is teasing with the apparently soon to be launched new Ethash miner called Antminer E9 that is supposed to be offering 3 GH/s mining hashrate with 2556 Watts of power usage and 0.85 J/M power efficiency. This is what they claim to be the equivalent of 32 RTX 3080 graphics cards and it roughly is in terms of performance. So, the Antminer E9 is going to be offering similar performance to 32x Nvidia GeForce RTX 3080 GPU mining rig mining Ethereum with GPUs optimized for close to 100 MH/s hashrate, but with power usage at just about 1/3 of what the GPUs will need. Hopefully with a price that is much less compared to how much these video cards will cost you currently, though there is still no exact launch date or pricing information released…

Bitmain however is not the first to upgrade their already outdated dedicated Ethash miner, namely the Bitmain Antminer E3 that has been around for ages. There are other competitors on the dedicated ETH miners market, namely Innosilicon and Linzhi. Innosilicon’s new ETH miner – the Innosilicon A11 is supposedly going to deliver 2100 MH/s Ethash hashrate with just 2300W of power usage, while the newcomer Linzhi and their Linzhi Phoenix ETH miner is supposedly capable of 2600 MHS hashrate for Ethash with a power usage of 3000-3500W. So, Bitmain is going to be doing better in terms of performance and with lower hashrate if the specs of their AntMiner E9 ETH miner end up to be right on the spot. It is very likely however that the price will also be reflecting the better hashrate and lower power usage as well, so it could be more expensive than the slower alternatives.

Bitmain has made available another SHA256 ASIC from their Antminer 19 series available for pre-order – the 84 TH/s Antminer T19 miner. In terms of power efficiency and hashrate the new T19 series device sits a little below the Antminer S19, sold at almost the same pre-order price, but starts shipping near the end of next month and not in September like if you pre-order S19 now. Antminer T19 offers 84TH/s hashrate at 3150 Watts of power or with other words 37.5 J/TH power efficiency and it comes with a built in power supply like other high power usage miners. With older ASIC mining hardware getting obsolete after the recent Bitcoin halving more miners will need to replace their old miners with new ones that are readily available and offer better power efficiency and hashrate… and that does not mean the ones with the fastest hashrate and highest price.

The latest NBMiner 30.0 update comes with a built-in replacement for the OhGodAnETHlargementPill memory timings optimization tool for Nvidia GPU owners of GTX 1080 and GTX 1080 Ti with GDDR5X video memory. The implementation from NBMiner does however requires the use of a custom unsigned driver under Windows and admin privileges under Linux, so not as easy as just running a custom executable file to enable the tweaks. Once implemented however it could allow for greater flexibility as you have the option to use different levels of optimizations for the memory timings via command line parameters. Have in mind that not all crypto algorithms may benefit from memory timings optimization, here are the two options you need to use to enable and activate the memory tings optimizations in the latest version of NBMiner.

--mt, --memory-tweak Memory timings optimize for Nvidia GDDR5 & GDDR5X gpus. range [1-6]. Higher value equals higher hashrate. Individual value can be set via comma seperated list. Power limit may need to be tuned up to get more hashrate. Higher reject share ratio can happen if mining rig hits high temperature, set lower value of -mt can reduce reject ratio. Under windows, a custom driver need to be installed before using -mt, see description of --driver for more detail. Admin priviledge is needed to run under linux, sudo ./nbminer -mt x. OhGodAnETHlargementPill is not needed anymore if -mt is enabled when mining on 1080 & 1080ti GPUs.
--driver Windows only option, install / uninstall driver for memory tweak. Run with admin priviledge. install: nbminer.exe --driver install, uninstall: nbminer.exe --driver uninstall. Note: the installed custom driver is not signed by microsoft, users need to disable secure boot in BIOS settings to get the driver work.

We remind you that the NBMiner is a closed source GPU miner for Nvidia CUDA and now AMD as well that is available for both Windows and Linux operating systems and it has the following developer fee built-in: tensority_ethash 3%, tensority(Pascal) 2%, tensority(Turing) 3%, ethash 0.65%, cuckaroo & cuckatoo & cuckaroo_swap 2%, progpow_sero 2%, sipc 2%, bfc 3%, hns 2%, hns_ethash 3%, trb 2%, trb_ethash 3%, kawpow 2%.
