Hash is referred to as a one-way function. The SHA256 algorithm creates a 256-bit (32-byte) hash that is nearly unique. The method will give a different hash result even if just one symbol is modified. It is usually preferable to hash and compare SHA256 values when comparing two pieces of raw data (file source, text, or similar). A cryptographic hash is similar to a data set's signature. Hope I have answered your question.One of a variety of cryptographic hash functions is the SHA (Secure Hash Algorithm). The total number of correct hashes sent by your GPUs per second will be your hash rate and the more computing power, more is the hash rate. The higher end GPUs easily solves the respective algorithm (SHA-256 in Bitcoin) and finds the 64 digit hash and submits it to the mining pool and all this happens in seconds. When you start mining any cryptocurrency, your computer will receive job from your mining pool and your GPUs try to figure out the 64 digit hash randomly. GPUs hash rate is simply how much hashes that it can solve/submit with a period of time. And you’re likely only going to see that performance for a few minutes, after which it slows to a crawl. In a laptop, especially one with such bottom of the heap GPU, it is a given that the cooling system is inadequarte.
this is when the cooling system can make the chip run at peak performance indefinitely. That is, if there is no throttling causing the chip to down clock when it gets too hot. But for the most part, you’re looking at cents worth only. It seems you “might” be able to get around $2 worth per day on a ZHash algorithm. Especially as it only has 2 GB of VRAM, precluding the most profitable mining of Ethereum (you need a minimum of 5 GB for that). Just like it would when you run a different strenuous program.Īlso, that 940MX is a low power, low performance dedicated GPU chip. Then, yes, it will get damaged as the high temperatures start to disorder stuff, and start to burn out circuit components (capacitors, resistors, even the transistors in the chip itself). Or if you go and turn off those safety features in BIOS. But, usually, people have replaced their machines long before this becomes an issue anyway. No longer working after 20 years of use, it might die after 10. If the laptop isn’t stupidly designed, it would throttle down or even shut down when it reaches dangerous temperatures.Ĭonstantly pushing it to the point where it throttles or shuts down, would likely shorten its average lifespan. Would it damage the GPU? No more than running those other strenuous programs would. Which is the major reason a desktop always outperforms an equivalent laptop.
They’re especially bad for heat dissipation, not allowing long-running programs to perform at peak speeds. However, laptops have some dismally poor limits. If you’re not doing something stupid, like overclocking the component beyond safe limits, there should be no reason it “dies” on you. Any sort of long-running program, pushing a component to perform at its peak, for a long time. In general, it is pretty much similar to running a strenuous game or doing rendering, video encoding, statistical analysis, etc. Mining in and of itself is just running a program.
