GPGPU: Bitcoin, Litecoin, LuxMark, And RatGPU

The following disciplines don't capture every aspect of general-purpose computing (there are still Photoshop, WinZip, and video editing benchmarks in our suite that we weren't able to run). Geforce gtx 660 mining, they geforce gtx 660 mining us a good idea of how Maxwell improves upon the Kepler architecture, and where Nvidia now sits relative to AMD.

BTC Mining

Although the company isn't going into depth on the improvements it made, we know that Maxwell handles hashing far better than Kepler, which is reflected by its victory over the GeForce GTX 680 and uranium mining in production. At least in BTC mining, however, GeForce GTX 750 Ti still gets hammered by Radeon R7 260X and some of AMD's other more mainstream cards.

Of course, Bitcoin isn't the only cryptocurrency reliant on hashing. MaxCoin, for example, geforce gtx 660 mining, is a member of the SHA3 family, and it's supported in the latest version of CudaMiner. Curious as to how GeForce GTX 750 Ti sizes up to 650 Ti, we ran the following SHA2-based test in Sandra 2014:

There are big gains to be had from DirectX's Compute Shader, but throughput via CUDA is downright phenomenal. It's probable that Maxwell improves some of the integer operations that were slower on Kepler. Hopefully Nvidia opens up more about what the new architecture can do.

LTC Mining

Bitcoin mining is almost irrelevant to CPU and GPU miners these days, if only because it's impossible to compete with dedicated ASIC- and FPGA-based devices working so mount lyell mining faster. But at least for a short time still, Litecoins remain at least a somewhat viable option. The use of scrypt (a password-based key derivation function) in their proof-of-work algorithm, rather than Bitcoin's SHA-256, makes dedicated hardware more difficult to develop. So, GPUs still rule, even if increasing difficulties make the investment in equipment and power greater than current returns.

Historically, Nvidia's cards came up short against competing Radeons, which is why you see R9 290X boards selling for $700 and up. But the Maxwell architecture's improvements allow the 60 W GeForce GTX 750 Ti to outperform the 140 W GeForce GTX 660 and approach AMD's 150 W Radeon R7 265, which just launched, still isn't available yet, but is expected to sell for the same $150. On a scale of performance (in kH/s) per watt, that puts Nvidia way out ahead of AMD. Today, four GM107-based cards in a mining rig should be able to outperform a Radeon R9 290X for less money, using less power.

LuxMark 2.0

LuxMark is another bastion for AMD, where the compute performance of its Ltc mining hashrate typically dwarfs competing Nvidia cards. The Radeons are so much faster, in fact, that Nvidia typically avoids addressing our results, stating only that it doesn't optimize for compute workloads on its gaming cards.

Again though, for a 60 W board, the GeForce GTX 750 Ti does pretty well. It still falls behind the Bonaire-based cards in its price segment. But compare its score of 943 to the GeForce GTX 580's 893. That's an almost-250 W former flagship!

Geforce gtx 660 ti mining : Bitcoin

As we have talked about on severaldifferentoccasions, Altcoin mining (anything that is NOT Bitcoin specifically) is a force on the current GPU market whether we like it or not. Traditionally, Miners have only bought AMD-based GPUs, due to the performance advantage when compared to their NVIDIA competition. However, with continued development of the cudaMiner application over the past few months, NVIDIA cards have been gaining performance in Scrypt mining.

The biggest performance change we've seen yet has come with a new version of cudaMiner released yesterday. This new version (2014-02-18) brings initial support for the Maxwell architecture, which was just released yesterday in the GTX 750 and 750 Ti. With support for Maxwell, mining starts to become a more compelling option with this new NVIDIA GPU.

With the new version of cudaMiner on the reference version of the GTX 750 Ti, we were able to achieve a hashrate of 263 KH/s, impressive when you compare it to the performance of the previous generation, Kepler-based GTX 650 Ti, which tops out at about 150KH/s or so.

As you may know from our full GTX 750 Ti Review,  the GM107 overclocks very well. We were able to push our sample to the highest offset configurable of +135 MHz, with an additional 500 MHz added to the memory frequency, and 31 mV bump to the voltage offset. All of this combined to a ~1200 MHz clockspeed while mining, and an additional 40 KH/s or so of performance, bringing us to just under 300KH/s with the 750 Ti.

As we compare the performance of the 750 Ti to AMD GPUs and previous generation NVIDIA GPUs, we start to see how impressive the performance of this card stacks up considering the $150 MSRP. For less than half the price of the GTX 770, and roughly the same price as a R7 260X, you can achieve the same performance.

When we look at power consumption based on the TDP of each card, this comparison only becomes more impressive. At 60W, there is no card that comes close to the performance of the 750 Ti when mining. This means you will spend less to run a 750 Ti than a R7 260X or GTX 770 for roughly the same hash rate.

Taking a look at the performance per dollar ratings of these graphics cards, we see the two top performers are the AMD R7 260X and our overclocked GTX 750 Ti.

However, when looking at the performance per watt differences of the field, the GTX 750 Ti looks more impressive. While most miners may think they don't care about power draw, it can help your bottom line. By being able to buy a smaller, less efficient power supply the payoff date for the hardware is moved up.  This also bodes well for future Maxwell based graphics cards that we will likely see released later in 2014.  

Continue reading our look at Coin Mining performance with the GTX 750 Ti and Maxwell!!

To illustrate this example, we put together two builds of mining computers that should be capable of similar hashrates:

In these two builds, the core platform stays the same, with the AMD Sempron 145 Single Core processor. While this processor would be essentially useless for a lot of other tasks, Coin mining on a GPU is not a CPU intensive task, so we can get away with one of  the cheapest CPUs on the market.

We chose the Gigabyte 990FXA-UD3, as it was the cheapest motherboard we could find for this platform with 6 PCI-Express ports.

As you have probably noticed not all of the PCI-E ports on this motherboard allow for a x16 card to be plugged in, and even the ones that are capable don't have proper spacing for 2 slot cards. To remedy this we have included the appropriate adapters.

Due to the fact that we are using PCIE risers, there is no case included. You would most likely be best served by building an open-air test bed for the system out of milk crates, shelving systems, wood, or some other building material. Just remember, it doesn't have to look pretty to be effective!

There is also no storage option included. For something like this you could either use any spare hard drive you have laying around, or even install a Linux distribution to a thumb drive. Due to this, we found storage to be a negligible option.

First, we have a more traditional build, using 4 x R9 270Xs, which we found available on Amazon right now for just above $300 each. With 4 of these cards running at about 450KH/s each, we should have a 1.8MH/s machine. With a power draw of 150W from each card, we get a total of 600W just for the GPUs alone. Throwing in another 75W for the 45W TDP processor and any additional overhead, we come to approximately 675W power draw for our entire mining rig.

At a total cost of around $1520, this machine would have a payoff period of about 113 days at the current Dogecoin rates, at 1.8MH/s

Our second build is based on the GTX 750 Ti. This time we instead opted for 6 x 750 Ti cards for a total of $900, which is still significantly lower than the $1200 for 4 270Xs. With 6 x 750 Ti cards, the estimated GPU power draw would only be 360W, just above half of the power draw of the 270X machine. Adding in the same 75W for additional system components the total estimated power draw works out to 435W, which allows us to purchase a cheaper power supply.

At a total cost of around $1300, this machine would have a payoff period of about 97 days at the current Dogecoin rates, at 1.8MH/s

As you can see, by cramming more of the lower end but impressive GTX 750 Ti's into a single machine you can create a similar performing machine for less money than the AMD alternative, which is contrary to all the advice given about coin mining up to this initial release of Maxwell. In addition, performance of the Maxwell-based machine should only improve as the Maxwell kernel for cudaMiner is developed further, whereas OpenCL performance for AMD mining has likely been as optimized as we will ever see it.

An additional factor you have to keep in mind is the fluctuating cryptocurrency market. Just because the payoff estimates today say you could be making a profit in 80 days, doesn't mean that will remain the same in the future. While the estimate could get better, it also could get a lot worse, leaving you with a lot of hardware to sell off in the future.

While no one is sure where the mining market will be as far as profitability is concerned when the high end Maxwell GPUs hit the market, NVIDIA could have a similar stock issues and an inability to deliver GPUs to gamers as we see AMD having today.
