Radeon R9 295×2 Ethash 50MH s Reviews & Features

Right now each gpu is doing about 10Mhash and together they make me about $3 a day. I was hoping I could get closer to twice that but I cant seem to get much out of it by overclocking. I have the memory at 1400Mhz stable and pushing it to 1600 causes one of the gpus to give up.

  • If anything, two discrete cards are often slightly faster—AMD and Nvidia have historically run these cards at a slightly lower clock speed to offset the heat problems intrinsic to running two high-powered GPUs in a single card.

Just because you have a 1,200-watt power supply doesn’t mean it can actually supply that much voltage across a single rail. Some companies ship power supplies with 15 to 20 amps of power across many rails instead of aggregating the capacity into one or two 12-volt rails. In response, AMD is escalating the arms race with its Radeon R9 295X2, another dual-GPU specimen. To begin, it sports Hawaii GPUs that run just a bit faster than the single-processor Radeon R9 290X. ” AMD asks, purportedly referring to the big budget and beefy power supply you need before buying its new Radeon R9 295X2. We benchmark the 500 W, dual-GPU beast against several other high-end configs before declaring a winner.

AMD Radeon R9 295X2 Profitability, Hashrate, Ethereum and Bitcoin Mining Calculator

Altogether this means we’re looking at a pair of top-tier Hawaii GPUs, each with their full 2816 SPs and 64 ROPs enabled. Otherwise compared to the retired 7990, the R9 295X2 should be a far more capable card, offering 40% more shading/texturing performance and 2x the ROP throughput staking cryptocurrency of AMD’s previous flagship. I recently picked up a used R9 295×2 in great condition and I have got it in my rig for mining. I got it on a dedicated 850 psu and I am running lolMiner on nicehash. I feel like I am not generating the kind of hash rate I was anticipating.

AMD Radeon R9 280X Hashrate

Any pack-in items – be it games or devices – will be the domain of the board partners this time around. Also, the AMD Mystery Briefcase was just a promotional item, so partners won’t be packing their retail cards quite so extravagantly. Although the days of AMD’s “small die” strategy have long since ended, one aspect of AMD’s strategy that they have stuck with since the strategy’s inception has been the concept of a dual-GPU card. AMD’s first modern dual-GPU card, the Radeon HD 3870 X2 (sorry, Rage Fury MAXX), came at a low point for the company where such a product was needed just to close the gap between AMD’s products and NVIDIA’s flagship big die video cards. However with AMD’s greatly improved fortune these days, AMD no longer has to play just to tie but they can play to win. AMD’s dual-GPU cards have evolved accordingly and these days they are the high-flying flagships of AMD’s lineup, embodying the concept of putting as much performance into a single card as is reasonably possible.

Test Hardware And Benchmarks

That’s more than 100 MHz lower than the GK110 on a GeForce GTX Titan. Wouldn’t you be better off building that supercomputer using two, three, or even four Titans? In any case, the fact that AMD went this route isn’t wholly surprising – there aren’t too many ways to move 500W of heat – but the lack of significant binning did catch us off guard. Dual-GPU cards are often (but not always) using highly binned GPUs to further contain power consumption, which isn’t something AMD has done this time around, and hence the reason for the R9 295X2’s doubled power consumption. So long as AMD can remove the heat then they’ll be fine, and from our test results it’s clear that AMD has definitely done some binning, but none the less it’s interesting that we aren’t seeing as aggressive binning here as in past years.

All that earns the AMD Radeon R9 295X2 our Editors’ Choice for high-end, multi-core graphics cards. As for the GTX Titan Z, NVIDIA’s forthcoming dual-GPU card is scheduled to launch later this month, and while it should be a performance powerhouse it’s also going to retail at $3000, twice the price of the R9 295X2. So although the GTX Titan Z can be used for gaming, we’re expecting it to be leveraged more for its compute performance than its gaming performance. In any case based on NVIDIA’s theoretical performance figures we have a strong suspicion that the GTX Titan Z is underclocked for TDP reasons, so it remains to be seen whether it’s even gaming performance competitive with the R9 295X2. The price for that level of performance and quality on a single card will be $1499 (€1099 + VAT), $500 higher than the 7990’s $999 launch price, and similarly $500 higher than NVIDIA’s closest competitor, the GTX Titan Black.

Whereas a reference Radeon R9 290X runs at up to 1000 MHz, the 295X2 gets a small bump to 1018 MHz. Yes, the processors are still subject to the dynamic throttling behavior we illustrated in The Cause Of And Fix For Radeon R9 290X And 290 Inconsistency. But because cooling is better this time around, we’ve been told that throttling shouldn’t be an issue. Join us in the reference article, have a peek at the product below that is the X2 and then let’s head on-wards into the review.

Still there is no profile for Kingdom Come but maybe one of the Crysis profiles will work hence it is Cryengine. I have just installed Kingdom Come Deliverance and I am only getting about fps. When I try to turn crossfire on in Radeon Software the app seems to restart and the option goes back to off. The profitability table shows the revenue from mining the most profitable coins (Bitcoin Ethereum) on AMD Radeon R9 295X2 per month.

This shouldn’t be an issue when frame pacing is working properly, since there are no dropped or runt frames to report. To that end, all of our testing happens in the aforementioned Rosewill Throne chassis. And rather than simply firing up benchmarks after an idle period, we heat up every card with several minutes of gameplay prior to recording results. Really though, AMD effectively addressed variability on its reference Hawaii-based board through a driver, visual studio vs sublime text and most third-party solutions are better-cooled. Given the relatively exotic cooling requirements for the R9 295X2, it comes as no great surprise that AMD is targeting the same luxury video card crowd that the GTX Titan pioneered last year when it premiered at $1000. This means using more expensive cooling devices, a greater emphasis on build quality with a focus on metal shrouding, and a few gimmicks to make the card stand out in windowed cases.

Multi-core (which are usually dual-core) graphics cards are typically a hard sell, even for a halo product. Most desktop gamers have motherboards that support at least two x16 PCI-Express slots, which allows for the installation of multiple GPUs in a conventional SLI or Crossfire configuration. Dual GPUs may save on PCI Express slots, but they also concentrate two heat-generating chips in a single PCB. Typically, there’s no performance difference between two high-end discrete cards in a multi-GPU configuration and one dual-chip card. If anything, two discrete cards are often slightly faster—AMD and Nvidia have historically run these cards at a slightly lower clock speed to offset the heat problems intrinsic to running two high-powered GPUs in a single card. If we add in SLI or Crossfire configurations, then the answer is no.

Although I use the Radeon Pro DUO for Compute and Blender rendering most of the time, many who bought the cards will want to game on them with game titles that supported DX11 Crossfire in the past. I will try wiping the drivers and installing the hybrid once again. I have also checked 20.1.4, in this one I also can turn on crossfire, but the only crossfire option for games is “off”.

However, methodology is also more relevant than ever, particularly in light of the dynamic clock rate behavior we described when AMD’s Radeon R9 290X first launched. To dissipate 500W of heat AMD has moved past blowers and even open air coolers, and moved on to a closed loop liquid cooler (CLLC). We’ll cover AMD’s cooling apparatus in more detail when we take a closer look at the construction of the R9 295X2, but as with AMD’s 500W target AMD is charting new territory for a reference card by making a CLLC the baseline cooler. With two Asetek pumps and a 120mm radiator to dissipate heat, the R9 295X2 is a significant departure from AMD’s past designs and an equally significant change in the traditionally conservative system requirements for a reference card. After much consumer speculation and more than a few teasers, AMD is releasing their long-awaited Hawaii-powered entry to their dual-GPU series of cards. With Hawaii AMD has a very powerful (and very power hungry) GPU at their disposal, and for its incarnation in the R9 295X2 AMD is going above and beyond anything they’ve done before, making it very clear that they’re playing to win.

But for the R9 295X2 AMD is once again turning up the heat, requiring new methods of cooling if they want to offer 500W of cooling while maintaining reasonable noise levels. We’re using a calibrated studio-quality microphone what is namecoin for all sound level measurements. It’s positioned at a 90° orientation 50 cm away from each graphics card. Results are collected after each card hits its peak operating temperature in our gaming benchmark.

We know that AMD and Nvidia both have next-generation cards already in the works, but the benefits of 20-nanometer manufacturing are expected to be fairly modest. The 4K resolution is still a mammoth workload, which means that it’ll still take multiple cards to drive high-end detail levels at top resolution for the foreseeable future. AMD fired a white-hot salvo back in 2011 with the introduction of its Radeon HD 7970, which easily dwarfed Nvidia’s GeForce GTX 580.

Nvidia’s R337.50 driver and AMD’s Catalyst 14.4 beta drivers were installed. With the R9 295X2, we’re moving to 4K testing, as well as 1080p, but we’ve kept our policy of testing games at maximum detail levels. Unfortunately, we were unable to secure a second Titan Black from EVGA for benchmarking in SLI. Thus, the GTX Titan Black should be compared against the R9 290X, with the understanding that a pair of these cards is generally expected to match the R9 295X2 in most cases. Finally, it’s worth noting that unlike the launch of the 7990, AMD isn’t doing any game bundle promotions for the R9 295X2. AMD hasn’t been nearly as aggressive on game bundles this year, and in the case of the R9 295X2 there isn’t a specific product (e.g. GTX Titan) that AMD needs to counter.
