New NVidia Card Possesses Unbelievable Power

NVidia’s month old Volta GPU architecture has finally seen usage in the newest Tesla V100 GPU. It’s not a gaming product, but one for supercomputers, simulations, AI and deep learning. It could possibly be used for cryptocurrency mining, too. AMD with their newest Vega line seem to be behind NVidia’s Tesla. Why?

NVidia’s Tesla Has Outrageous Levels of Performance

Compared to the previous generation, Pascal-based Tesla P100, the new V100 GPU has 12 times greater deep learning performance, with 120 TFLOPs of “DL training”. The P100 has “only” 10 TFLOPs. The Volta version has also a gargantuan memory bandwith – over 900GB per second! Again, from “just” 720GB/sec on the P100. NVLINK 2.0 throws the internal bandwith up from 160GB/sec to a huge 300GB/sec while having 10MB of L1 Cache (Pascal had only 1.3MB). The card received an unreal Geekbench score of 743,537, and the only card that can come close is the Pascal version, with 320,031 points.

NVidia

AMD is extremely far behind, having nothing to compete with the monster that is NVidia’s Tesla. Until Radeon Instinct cards surface, AMD won’t be even coming close to the power of Tesla. Still, it is unlikely that the new AMD cards will outperform this top shelf product. As such, NVidia remains the king of the GPU market.

Nvidia Titan V Review

The recent technology boom in AI, deep learning and neural networks spawned a hunger for increasingly better hardware, with higher and higher processing power. Specifications are what always was the limiting factor for projects such as video games and research. Blowing every other consumer product out of the water, here comes in the Nvidia Titan V. With that GPU, sky is the limit, and of course, due to its beyond amazing specifications, you can use it for cryptocurrency mining. Let’s take a look.

Nvidia Titan V Hardware Specifications

 

titan v

• Graphics Processing Clusters: 6
• Streaming Multiprocessors: 80
• CUDA Cores (single precision): 5120
• Texture Units: 320
• Base Clock (MHz): 1200 MHz
• Boost Clock (MHz): 1455 MHz
• Memory Clock: 850 MHz
• Memory Data Rate: 1.7 Gbps
• L2 Cache Size: 4608K
• Total Video Memory: 12288 MB HBM2
• Memory Interface: 3072-bit
• Total Memory Bandwidth: 652.8 GB/s
• Texture Rate (Bilinear): 384 GigaTexels/sec
• Thermal Design Power (TDP): 250 Watts

 

As you can see, the Titan V is a powerhouse. And it draws only 250 Watts of power! For the purpose of cryptocurrency mining, this certainly would be a cost effective GPU if not for the price tag, which amounts to $3000. How fast would such a piece of hardware return our investment if we used it for mining?

Mining Performance of Titan V

In one of the tests, the GPU produced 82MH/s mining Ethereum. Provided the power costs $0.12 KW/h, we’ll get $205 of profit per month from the Titan V. This means it would take us about 15 months to make the $3000 back, provided the price of ETH stays the same and so do our power costs. I reckon there are better ways to invest your $3000, but this isn’t too shabby if you wish to use it as an AI research platform. Now, looking at Monero, we’d have to mine for twice as long, because the GPU will give us 1420H/s, and that amounts to $105 profit per month. Not that good. If you want to mine, it’ll be better to focus on other GPUs. In a year, the whole cryptocurrency market will change and so will the hardware, therefore betting on profit from a $3000 GPU isn’t the best idea.

Summary

The Nvidia Titan V is certainly a monster, but not a product designed for mining crypto. Using it for that purpose would be akin to buying a Ferrari just to drive to the groceries. Sure, you’ll own an impressive car, your friends will be in awe, but is that really money well spent? First and foremost, this is a product for research, and I’m sure that’s where it surely shines and the $3000 price tag is worth it.

NVIDIA GeForce GTX 1070 Ti Review

Nvidia Geforce

Cryptocurrency mining is one of the most widespread activities in the planet because of its profit-earning potential and the thrill you get when you obtain cryptocurrency, which will later go into your bank account in some way or another.

Not so long ago, cryptocurrency mining, especially Bitcoin mining, was performed on the Central Processing Units (CPU) of personal computers, and it was widely understood that with additional cores and faster speeds, people would get more money. But that system was later substituted, at least in popularity, by multi-graphic card systems that could help miners to find more hashes while optimizing the use of power.

NVIDIA’s newest toy for miners around the world

NVIDIA, an American technology brand, designs and produces graphics processing units, commonly known as GPU, for several fields, including cryptocurrency, gaming, and home use. It has been functioning since 1993. It also works on personal computers, mobile devices, and the automotive industry. NVIDIA is famous worldwide for its GeForce GPU series, which are commonly used for miners in their quest to add transactions to the blockchain and earn monetary rewards.

The GTX 1070 Ti comes to the market as a gaming GPU, although miners, naturally, have taken interest in its features and performance. It is visually attractive, with a colored LED logo and lights. According to some reviews, this card is very similar, if only marginally better, than the AMD RX Vega 64 and less than 10% better than the original GTX 1070 series, although we will talk more about that in a few minutes.

You will need more than your usual share of hardware to adapt your NVIDIA GTX 1070 Ti card: a motherboard such as the ASRock H81 PRO BTC, or the GIGABYTE GA-H110-D3A; an Intel Celeron G1840 for ASRock H81 PRO BTC CPU, or Intel Celeron G3900 for Gigabyte H110-D3A, at least 4 GB of DDR3, a SSD ADATA SU700 120GB, and an Add2PSU Multiple Power Supply Adapter, among other options.

The NVIDIA GeForce GTX 1070 Ti is an excellent graphics card for cryptominers all over the world. It has many interesting features, such as 512 more CUDA cores than the GeForce GTX 1070 while still implementing GDDR5 memory.

When mining Ether, the NVIDIA GeForce GTX 1080 isn’t as good as the cheaper GeForce GTX 1070, because speed and latency of the memory subsystem are deciding factors, and the latter comes up better in the comparison in spite of the former having GDDR5X.

More affordable than the competition, but not the best price

This new option in the market, the NVIDIA GeForce GTX 1070 Ti Founders Edition, can be obtained with $449, which isn’t considered terribly expensive if you consider that the NVIDIA GeForce GTX 1070 Founders Edition has a price of $399, and the NVIDIA GeForce GTX 1080 Ti FE costs $699.

Experiments have shown that the all-new NVIDIA GeForce GTX 1070 Ti with 432 CUDA Cores and 8GB of GDDR5 memory at 8Gbps is faster for Ethereum mining than, say, the GeForce GTX 1070. However, the margin is awfully small (only 0.2 MH/s), so the additional CUDA cores don’t heavily affect the performance. Let’s remember that both cards have equal bandwidth (256 GB/sec.)

The memory subsystem performance showed that some of the GeForce GTX 1070/1070 Ti cards stayed at 2000 MHz when mining, while others dropped to the 1900 MHz range. The problem seems to be present only for mining because other 3D applications didn’t drop the memory clock. However, manually overclocking the memory to the maximum level will get the best from the card anyway, so you don’t have to worry so much about this little issue.

On an overclocked 1070 Ti card, you will get close to 31 MH/s in performance, which represents roughly a 10% jump in production when compared to the EVGA GeForce GTX 1070 Ti FTW2. With the latter, the Graphics Processing Unit (GPU) was at 65C after mining for nearly nine hours in the open air, at approximately 634 RPM.

Both video cards, the EVGA GeForce GTX 1070 Ti FTW2 and the NVIDIA GeForce GTX 1070 Ti Founders Edition, are very similar in performance and power consumption, but since the former is $50 more expensive than the latter, then the decision is a lot easier for miners.

The NVIDIA GeForce GTX 1070 series cards give users better value for their price

However, the elite are still the NVIDIA GeForce GTX 1070 series cards. It offers miners some of the best features and performance in the market while costing just $379. With them, you could reach 33 MH/s by overclocking, a number that either the EVGA GeForce GTX 1070 Ti FTW2 and the NVIDIA GeForce GTX 1070 Ti Founders Edition could reach. In spite of having extra CUDA cores, the 1070 Ti aren’t particularly better for Ethereum miners.

In conclusion, while the NVIDIA GeForce GTX 1070 Ti has many interesting features that set it apart from its peers, evidence still suggests that the NVIDIA GeForce GTX 1070 series cards are better and more suitable for mining Ethereum, because, among many other things, it achieves better performance while using similar amounts of energy and power.

There is no denying that the NVIDIA GeForce GTX 1070 Ti has many positive traits. It has an excellent cooling system, it has mosfets and capacitors that make it durable and stable, it has even further overclock potential, it is silent and convenient for many environments, and is stylish and good-looking. However, it may be better suited for gamers than it is for cryptominers, and can be sold as a card for gamers with no issues. When it is set on factory configuration, the NVIDIA GeForce GTX 1070 Ti has a disappointingly low hash rate, and if you take in consideration the price, you can say it is good, but not top-notch.

Best GPUs for Mining

One of the reasons cryptocurrencies are popular is that there is no central authority running the system or minting the money. It is done by users. It is not only a good way to ensure a decentralized system, but it is also a great way to earn cryptocurrency tokens and earn huge profits.

Miners are paid for their efforts in the form of cryptocurrency tokens. If you can mine coins regularly, you can turn a huge profit pretty soon. But since mining is a race, you have to be the first to get the result. The mining GPU you use thus plays a big role in determining your success, which is why you should pick your mining GPU with care.

Best GPU for mining

A lot of factors play a part in determining the quality of a GPU. There are aspects of hash rate, power consumption, etc. that you have to consider before making a decision.

1) AMD Radeon RX 580

Redon

If you are looking for a GPU that ticks all the boxes, then the AMD Radeon RX 580 is one of the top candidates. With it, you get top-notch performance, reliability, a good chance of success, all at a good and affordable rate. With a hash rate of 29 MH/s, 8GB DDR5 memory, and 185W power draw, it is a GPU that packs a punch.

The best part of this mining GPU is that the device does not get very hot in a short time. This is in no small part due to the cooling system it has. The only problem with its efficiency is that it is often sold out as a result. If you’re lucky, you can get your hands on it.

2) Nvidia GeForce GTX 1070

Nvidia GeForce GTX 1070

Nvidia GeForce GTX 1070 is popular in the gaming community for its quality performance in the long run, but its usefulness is not limited to gaming. It is also one of the best mining GPUs you can find on the market today.

With a hash rate of 30 MH/s and a power consumption of 150W, it offers great computational capacity without drawing too much power. Lower power consumption always reduces your cost of mining, which only adds to your profit. The only problem though is that it is quite expensive and requires that one big first-time investment.

3) Nvidia GTX 1080 Ti

Nvidia GTX 1080 Ti

This is arguably the strongest graphics card on the market as of now. The reason it is not number one on the list is that it is quite expensive to buy and to run, but its power and performance prevent it from slipping any further down the pecking order. The Nvidia GTX 1080 Ti is the recommended choice for 4k gaming, and it is one of the best mining GPUs available.

The 11 GB GDDR5X memory and the 32 MH/s hash rate are lucrative stats, even if you are slightly discouraged by its 250W power rating. If you are running on a tight budget, then this is not your cup of tea. But if you don’t mind paying a substantial amount up front and can maintain the running cost, then you won’t find a better GPU than the Nvidia GTX 1080 Ti.

4) AMD Raedon RX Vega 56

AMD Radeon RX Vega 56

AMD Raedon RX Vega 56 is probably the best that AMD has to offer in terms of performance. Although a little pricey to get and run, it certainly delivers. The 8GB HBM2 memory gives it some power, which makes it better at computation than the Nvidia GTX 1070. It is also a little cheaper than the Nvidia GTX 1070, but requires more power with a 210W rating and also gets hotter as you use it.

5) AMD RX 480

AMD Radeon RX 580

With the Nvidia GTX 1080 Ti we highlighted an expensive GPU, so we now go to a low-cost GPU with the AMD RX 480. The low cost of the GPU does not mean it does not perform well. While it is older than the RX 580, it does have an 8GB DDR5 memory and provides a hash rate of 28 MH/s at 150W. You don’t have to splurge a lot to get it, and you don’t have to spend a lot to run it for a long time. The only challenge is finding it since it is not available most of the time due to high demand.

Mining is a proper business today, and like all businesses, the profits you earn depend on a lot of factors. One of these factors is the GPU you use for mining, which is why you should do some research before making a choice.
