As a general rule of thumb: Cryptonight, the PoW hash Monero uses, needs a 2 MB scratchpad in fast memory, so you will want to have all your mining threads able to keep their scratchpad in cache. So the optimal number is likely to be your cache size divided by 2 MB (eg, if your cache size is 4 MB, then 2 threads). If that number happens to be higher of equal ...

In terms of power efficiency, the reigning champ was the Nvidia 750Ti. That GPU will get you 250H/s and use about 30-40W power. For efficiency, that puts it around 6H/s/W. With the optimized ARM64 code I've been working on, a small ARM64 box (like a high end TV box) can get you 22H/s using less than 5W power. Much slower mining, but much higher efficiency, ...

There are no ASICS yet, and GPUs are about 2-4x faster than CPUs. Monero's PoW algorithm has a large memory requirement that would make it difficult to use an ASIC and less advantageous to use a GPU over a CPU than in Bitcoin. From the Monero Missives: We're also quite happy to announce the addition of a new feature to Monero: Smart Mining. This is a ...

People visiting this question in the future will find the answers provided are out of date. This website lists user-submitted hardware benchmarks that include Monero mining hashrate, power consumption, and configuration settings. The creator told me they were adding features to make it easier to search and sort the data. EDIT: the original bytehost5 URL ...

Wolf's GPU miner works with AMD integrated GPUs too. I tested it several months ago. https://twitter.com/hyc_symas/status/695730032291917825 On the A10-4600M each CPU thread got about 50H/s. In my laptop, the dGPU gets about 90H/s. The iGPU gets around 40H/s. These numbers are from memory and I may be misremembering. With the current AMD driver on Linux, ...

I played around a bit with using different numbers of threads on different machines, and my best results came from just using half the number of cores on that machine. Here's part of my script to launch minerd on macOS: numCores=$(sysctl hw.logicalcpu | awk '{print $2}') ((numCores = numCores / 2)) ./minerd -a cryptonight -o stratum+tcp://$pool -...

Nothing special to do if you're pool mining. Most pools just use your address as your "account name" and don't care if one device or 100 are mining to that address. As an example, some miners periodically point their miner to the Dev's donation address as a way to contribute. A small caveat... it could be best to pick one pool and devote all your resources ...

Currently the rx400 series is the most efficient, powerful, and cost-effective mining equipment. I have gotten an rx470 to 700 h/s using about 80-90 watts. It required many hours of bios modification, but this is all doable with readily available software.

Monero could be mined by ASIC. The Bitmain Antminer X3 is U$1255, ships Aug. 21-31 2018, and weighs 7 kg, it does 220000 H/s using 465 W +7% (2.27 J/kH +7%) - but they clearly mention: There are financial risks associated with mining cryptocurrencies. These risks can be related to changes in exchange rate of the cryptocurrency or to changes in the algorithm ...

The "24-Core" supported by the motherboard you linked to is per-CPU, (e.g., E7-8890 v4 has 24 cores), so per quad-socket motherboard that would be 96 cores. However, these CPUs cost >$7K each yet you won't benefit much from the n-way architecture when mining. Compare that with less than half that price for a 20-Core, 2-way CPU. Those n-way motherboards are ...

Cheapest GPU is the one you have available. I mean, you can start mining with an integrated GPU like an AMD Radeon HD 7480D and get around 50 H/s. If you want a full list of GPU Benchmarks, feel free to check my website: http://monerobechmarks.byethost5.com/ Website's Reddit Thread Website's Bitcointalk Thread

This depends on whether you refer to "performance per watt" or "performance per purchase price". Raw hash rates for different CPUs and GPUs can be found, for example, at http://monerobenchmarks.info/index.php In terms of performance per watt (which is easiest to measure/calculate): a Xeon Phi 7210 gets 2770H/s @ 225W, that's 12.3 H/J a Dual AMD Epyc gets ...

Yes, since Z3735F has x86_64 instruction set. But there is no AES so you will get a very small hash rate, and considering its design, it will probably overheat, so most probably not worth it.


4

You can start the same command line one each machine and it will work. However, if you have hardwares with significant difference in hashrate, it may be better to target a specific difficulty. That can be done by choosing the pool port and/or, if the pool handles it, by specifying a worker id. From dwarfpool http://dwarfpool.com/xmr : You can determine ...

GPU mining configurations often use the cheapest CPU. Thus, your CPU should be powerful enough to work with 3 Rx 480. Yes, PCIE x 1 should work for mining but you have to buy a riser (recommended to use a powered riser). RX 480 draws around 150W (from specification) - 200W. Probably give some more allowance when buying your Power Supply and don't go cheap ...

According to these benchmarks, K620 is supose to get around 120 H/s http://monerobenchmarks.info/ (threads 32, block 6s) Also XEON E3-1271 gets 338 H/s So yes, its probably correct. But you can always tweak it a little bit.

Its really not that hard. Create your wallet (GUI works well) install: XMR-Stak XMR-Stak seems to work well (one unified version for CPU & GPUS:AMD/NVidia). I did build it for linux, but there are prebuilt versions. Then fire it up, answer questions (no to nicehash, and probably no to multiple pools) and point to to a pool (monerohash.com, ...

Mining to the same address with several machines it totally fine. Difficulty adjustment is made per connection, so having machines with wildly disparate hash rate mining to the same address is fine. The pool will show the aggregate hash rate for an address.


3

I run several instances of two different clients (CPU and GPU) on the same pool with no problem at all. No special configuration.

The most efficient hardware for mining Monero, at this time, are AMD GPU cards. High hashrate power and low power consumption is the perfect combination. Truly, the more cost-efficient hardware for Monero mining is the AMD Radeon Vega card. Both 56 and 64 VEGA cards are notably profitable in mining Monero. Radeon VEGA 56 can mine with stock BIOS around ...

I have two R9 290's online mining. I have an AMD Sapphire running approximately 723h/s sure I can do it a little better. Also have a PowerColor running but its only at 636h/s hopefully that will give you a little idea. A lot depends on the model.


3

What I'd like to do is have all these devices mine to a single address, without joining a pool. Is this possible? You can use the start_mining <addr> monerod command for each miner and direct all mined XMR to a single address under your control.


3

You can try mining with monero-wallet-cli to see your hashrate but I'm pretty sure it will be below 30H/s (a laptop i3 CPU). With this, you'd be getting about 0.006xmr/day. You can estimate mining profits here, just scroll down a bit and type in your hashrate.


3

With that budget I'd probably build a rig around the following components: AsRock H110 Pro BTC+ (~140€) 6xMSI GTX 1060 GAMING X6G (~360€ each = 2160€ total) One GTX 1060 overclocked using the following settings will be able to sustain about 540 H/s resulting in 3.2 kH/s with very moderate power consumption: Core Clock +200 MHz Memory Clock +800 MHz Power ...

I would say that it will not automatically mine better. What is important is the cache size of the CPU. You need 2 MB for one thread. Let's say your cache is 4 MB and you have 8 cores, you still can only mine with 2 threads - or at least having more cores doesn't help.

AMD Threadripper is clearly better. Take a look at this german article. If you don't understand german, take a look at the table with the number of threads. The more threads the better. On the second page you will then see the relevant charts Here are the details from that article Cache size and optimal number of threads CPU ...

What are the main differences between ProgPOW and RandomX? The design goal of ProgPoW is to have the algorithm’s requirements match what is available on commodity GPUs, while RandomX is inefficient (as stated on https://github.com/tevador/RandomX) on GPUs. can some parts of it also benefit Monero's development in a longer-term ASIC resistant mining ...

AFAIK, there is strictly no correlation between the hash speed of different hashing algorithms. I guess it can possibly make sense for hardware that are capable of dual mining. But, currently, hardware for SHA-256 & scrypt are ASICs, so they won't work for others hashing algorithms
