Overview

There has been a lot of news lately about the release of Cryptocurrency-specific graphics cards from both NVIDIA and AMD add-in board partners. While we covered the currently cryptomining phenomenon in an earlier article, today we are taking a look at one of these cards geared towards miners.

It's worth noting that I purchased this card myself from Newegg, and neither AMD or Sapphire are involved in this article. I saw this card pop up on Newegg a few days ago, and my curiosity got the best of me.

There has been a lot of speculation, and little official information from vendors about what these mining cards will actually entail.

From the outward appearance, it is virtually impossible to distinguish this "new" RX 470 from the previous Sapphire Nitro+ RX 470, besides the lack of additional display outputs beyond the DVI connection. Even the branding and labels on the card identify it as a Nitro+ RX 470.

In order to test the hashing rates of this GPU, we are using Claymore's Dual Miner Version 9.6 (mining Ethereum only) against a reference design RX 470, also from Sapphire.

On the reference RX 470 out of the box, we hit rates of about 21.8 MH/s while mining Ethereum. 

Once we moved to the Sapphire mining card, we move up to at least 24 MH/s from the start.

Is it time to buy that new GPU?

Testing commissioned by AMD. This means that AMD paid us for our time, but had no say in the results or presentation of them.

Earlier this week Bethesda and Arkane Studios released Prey, a first-person shooter that is a re-imaging of the 2006 game of the same name. Fans of System Shock will find a lot to love about this new title and I have found myself enamored with the game…in the name of science of course.

Prey-2017-05-06-15-52-04-16.jpg

While doing my due diligence and performing some preliminary testing to see if we would utilize Prey for graphics testing going forward, AMD approached me to discuss this exact title. With the release of the Radeon RX 580 in April, one of the key storylines is that the card offers a reasonably priced upgrade path for users of 2+ year old hardware. With that upgrade you should see some substantial performance improvements and as I will show you here, the new Prey is a perfect example of that.

Targeting the Radeon R9 380, a graphics card that was originally released back in May of 2015, the RX 580 offers substantially better performance at a very similar launch price. The same is true for the GeForce GTX 960: launched in January of 2015, it is slightly longer in the tooth. AMD’s data shows that 80% of the users on Steam are running on R9 380X or slower graphics cards and that only 10% of them upgraded in 2016. Considering the great GPUs that were available then (including the RX 480 and the GTX 10-series), it seems more and more likely that we going to hit an upgrade inflection point in the market.

A simple experiment was setup: does the new Radeon RX 580 offer a worthwhile upgrade path for those many users of R9 380 or GTX 960 classifications of graphics cards (or older)?

Sapphire Launches New Pulse Series of Graphics Cards

Subject: Graphics Cards | April 25, 2017 - 03:11 AM |
Tagged: sapphire, RX 580, RX 550, pulse, Polaris, nitro+, GCN

Earlier this month Sapphire announced a new budget-oriented series of graphics cards it calls PULSE. The new series slides in below the premium Nitro+ series to offer cheaper graphics cards that retain many of the high-quality hardware components but lack the flashy extras on the coolers, come in at lower factory overclocks, and have fewer PCI-E power inputs which, in theory, means lower overclocking headroom. The new graphics cards series is currently made up of five Polaris-based GPUs: the Sapphire Pulse RX 580, RX 570, RX 570 ITX, and RX 550.

According to Sapphire, Pulse graphics cards use many of the high-end components as the Nitro+ cards including Black Diamond Chokes 4, long lasting capacitors, fuse protection. And intelligent fan control. The new graphics cards have aluminum backplates, removeable Quick Connect fans with semi-passive cooling technology that allows the fans to turn off when the card is under light load. The RX 580 and RX 570 use Dual-X coolers and the RX 570 ITX and RX 550 use single fan shrouded coolers.

Compared to Nitro+, the coolers are a bit less flashy and there are no Nitro+ Glow LEDs. If you are not a fan of bling or do not have a windowed case, the Pulse cards might save you a bit of money while getting you most of the performance if Sapphire’s claims are accurate.

Speaking of performance, the Pulse branded graphics cards are factory overclocked, just not as much. The Sapphire Pulse RX 580 with its 2,304 cores comes with a boost clock of 1366 MHz, the RX 570 and RX 570 ITX come with GPU boost clocks of 1,284 MHz and 1,244 MHz respectively, and the RX 550 has a boost clock of 1,206 MHz. Memory clocks sit at 8,000 MHz for the RX 580 and 7,000 MHz for the remaining Pulse cards (RX 570, RX 570 ITX, and RX 550).

Along with the introduction of its new Pulse series of graphics cards, Sapphire has entered a “strategic partnership” with motherboard manufacturer Asrock. The new graphics cards are shipping now and will be available at retailers shortly. Pricing for the RX 550 isn’t available, but prices for the other cards has appeared online as follows: Pulse RX 580 8GB for $229.99, Pulse RX 580 4GB for $199.99, Pulse RX 570 for $179.99, Pulse RX 570 ITX for $169.99.

In all, the Pulse cards appear to be about $20 cheaper than the Nitro+ variant. We will have to wait and see if those prices hold up once retailers get stock in.

The RX 580 on Linux, locked stock and overclock

Subject: Graphics Cards | April 24, 2017 - 06:08 PM |
Tagged: linux, RX 580, amd, overclocking, Polaris

Phoronix have had a chance to test out the refreshed Polaris RX 580 on the Linux 4.11 kernel and Mesa 17.1-devel, initially the AMDGPU-PRO 17.10 driver update was not included thanks to interesting timing.  The performance deltas are as you would expect, a slight increase in performance that is relative to the increased clock speeds, just as when run on Windows.  They also had a chance to try overclocking the new card, AMD added support for overclocking GCN 1.2 and newer cards on their proprietary Linux driver in 2016.  They managed to increase the core by 6% without running into stability issues however when they overclocked the memory, they saw serious performance decreases.  Check out the steps they tried along with the results from the overlocked GPU here.

"Yesterday I posted the initial Radeon RX 580 Linux benchmarks while now with having more time with this "Polaris Evolved" card I've been able to try out a bit more, like the AMDGPU Linux overclocking support. Here are the ups and downs of overclocking the Radeon graphics card under Linux."

Teaching an old star new tricks, the Radeon RX 580

Subject: Graphics Cards | April 18, 2017 - 04:04 PM |
Tagged: RX 580, radeon, Polaris, amd, powercolor, red devil

Ryan covered the improvements over the previous Polaris based cards the RX 580 offers, a higher Rated Clock and standardizing memory frequency of all RX 580 models to 8GHz.  That lead to the expected increase in performance compared the the RX 480, in a marketplace somewhat different than what the first Polaris chips arrived in.  Consumers now know what NVIDIA's current generation cards provide in performance and prices have settled as much as can be expected in the volatile GPU market.  Those using cards several generations old may be more receptive to an upgrade than they were with the previous generation, especially as the next large launches are some time off; we shall see if this is true in the coming months.

One particular reason to consider upgrading is VR support, something [H]ard|OCP covers in their review.  The improved speeds do not provide miracles in their VR Leaderboard however they do show improvements in some games such as Serious Sam, with reprojection rates dropping markedly.

"AMD is launching the AMD Radeon RX 500 series today, and we lead with a custom retail Radeon RX 580 GPU based video card from PowerColor. We’ll take the Red Devil RX 580 Golden Sample video card through the paces and see how it compares to the competition at the same price point."

What is old is new again

Trust me on this one – AMD is aware that launching the RX 500-series of graphics cards, including the RX 580 we are reviewing today, is an uphill battle. Besides battling the sounds on the hills that whisper “reeebbrraannndd” AMD needs to work with its own board partners to offer up total solutions that compete well with NVIDIA’s stronghold on the majority of the market. Just putting out the Radeon RX 580 and RX 570 cards with same coolers and specs as the RX 400-series would be a recipe for ridicule. AMD is aware and is being surprisingly proactive in its story telling the consumer and the media.

  • If you already own a Radeon RX 400-series card, the RX 500-series is not expected to be an upgrade path for you.
     
  • The Radeon RX 500-series is NOT based on Vega. Polaris here everyone.
     
  • Target users are those with Radeon R9 380 class cards and older – Polaris is still meant as an upgrade for that very large user base.

The story that is being told is compelling; more than you might expect. With more than 500 million gamers using graphics cards two years or older, based on Steam survey data, there is a HUGE audience that would benefit from an RX 580 graphics card upgrade. Older cards may lack support for FreeSync, HDR, higher refresh rate HDMI output and hardware encode/decode support for 4K resolution content. And while the GeForce GTX 1060 family would also meet that criteria, AMD wants to make the case that the Radeon family is the way to go.

slides-10.jpg

The Radeon RX 500-series is based on the same Polaris architecture as the RX 400-series, though AMD would tell us that the technology has been refined since initial launch. More time with the 14nm FinFET process technology has given the fab facility, and AMD, some opportunities to refine. This gives the new GPUs the ability to scale to higher clocks than they could before (though not without the cost of additional power draw). AMD has tweaked multi-monitor efficiency modes, allowing idle power consumption to drop a handful of watts thanks to a tweaked pixel clock.

Maybe the most substantial change with this RX 580 release is the unleashing of any kind of power consumption constraints for the board partners. The Radeon RX 480 launch was marred with issues surrounding the amount of power AMD claimed the boards would use compared to how much they DID use. This time around, all RX 580 graphics cards will ship with AT LEAST an 8-pin power connector, opening overclocked models to use as much as 225 watts. Some cards will have an 8+6-pin configuration to go even higher. Considering the RX 480 launched with a supposed 150 watt TDP (that it never lived up to), that’s quite an increase.

slides-13.jpg

AMD is hoping to convince gamers that Radeon Chill is a good solution to help some specific instances of excessive power draw. Recent drivers have added support for games like League of Legends and DOTA 2, adding to The Witcher 3, Dues Ex: Mankind Divided and more. I will freely admit that while the technology behind Chill sounds impressive, I don’t have the experience with it yet to claim or counterclaim its supposed advantages…without sacrificing user experience.

The Sapphire RX460 1024SP edition offers a full Polaris 11 core operating at 1250 MHz, and it otherwise matches the specifications of a stock RX460 graphics card. Whether this product will be available outside of China is unknown, as is the potential pricing model should it be available in the USA. A 4GB Radeon RX460 retails for $99, while the current step-up option is the RX470, which doubles up on this 1024SP RX460's shader count with 2048, with a price increase of about 70% ($169).

Performance and Impressions

This content was sponsored by AMD.

Last week in part 1 of our look at the Radeon RX 460 as a budget gaming GPU, I detailed our progress through component selection. Centered around an XFX 2GB version of the Radeon RX 460, we built a machine using an Intel Core i3-6100, ASUS H110M motherboard, 8GB of DDR4 memory, both an SSD and a HDD, as well as an EVGA power supply and Corsair chassis. Part 1 discussed the reasons for our hardware selections as well as an unboxing and preview of the giveaway to come.

In today's short write up and video, I will discuss my impressions of the system overall as well as touch on the performance in a handful of games. Despite the low the price, and despite the budget moniker attributed to this build, a budding PC gamer or converted console gamer will find plenty of capability in this system.

Check out prices of Radeon RX 460 graphics cards on Amazon!!

Let's quickly recap the components making up our RX 460 budget build.

Our Radeon RX 460 Build

  Budget Radeon RX 460 Build
Processor Intel Core i3-6100 - $109
Cooler CRYORIG M9i - $19
Motherboard ASUS H110M-A/M.2 - $54
Memory 2 x 4GB Crucial Ballistix DDR4-2400 - $51
Graphics Card XFX Radeon RX 460 2GB - $98
Storage 240GB Sandisk SSD Plus - $68
1TB Western Digital Blue - $49

The completed system is damn nice looking, if I do say so myself. The Corsair Carbide 88R case sports a matte black finish with a large window to peer in at the hardware contained within. Coupled with the Nixeus FreeSync display and some Logitech G mouse and keyboard hardware we love, this is a configuration that any PC gamer would be proud to display.

Our Radeon RX 460 Build

This content was sponsored by AMD.

Be sure you check out part 2 of our story where we detail the performance our RX 460 build provides as well as our contest page where you can win this PC from AMD and PC Perspective!

Just before CES this month, AMD came to me asking about our views and opinions on its Radeon RX 460 line of graphics cards, how the GPU is perceived in the market, and how I felt they could better position it to the target audience. It was at that point that I had to openly admit to never actually having installed and used an RX 460 GPU before. I know, shame on me.

I like to pride myself and PC Perspective on being one of the top sources of technical information in the world of PCs, gaming or otherwise, and in particular on GPUs. But a pitfall that I fall into, and I imagine many other reviewers and media do as well, is that I overly emphasize the high end of the market. And that I tend to shift what is considered a “budget” product up the scale more than I should. Is a $250 graphics card really a budget product that the mass market is going to purchase? No, and the numbers clearly point to that as fact. More buyers purchase cards in the sub-$150 segment than in any other, upgrading OEMs PCs and building low cost boxes for themselves and for the family/friends.

So, AMD came to me with a proposal to address this deficiency in my mental database. If we were willing to build a PC based on the RX 460, testing it and evaluating it honestly, and then give that built system back to the community, they would pay for the hardware and promotion of such an event. So here we are.

To build out the RX 460-based PC, I went to the experts in the world of budget PC builds, the /r/buildapc subreddit. The community here is known for being the best at penny-pinching and maximizing the performance-per-dollar implementations on builds. While not the only types of hardware they debate and discuss in that group, it definitely is the most requested. I started a thread there to ask for input and advice on building a system with the only requirements being inclusion of the Radeon RX 460 and perhaps an AMD FreeSync monitor.

Check out prices of Radeon RX 460 graphics cards on Amazon!!

The results were impressive; a solid collection of readers and contributors gave me suggestions for complete builds based around the RX 460. Processors varied, memory configurations varied, storage options varied, but in the end I had at least a dozen solid options that ranged in price from $400-800. With the advice of the community at hand, I set out to pick the components for our own build, which are highlighted below:

Our Radeon RX 460 Build

  Budget Radeon RX 460 Build
Processor Intel Core i3-6100 - $109
Cooler CRYORIG M9i - $19
Motherboard ASUS H110M-A/M.2 - $54
Memory 2 x 4GB Crucial Ballistix DDR4-2400 - $51
Graphics Card XFX Radeon RX 460 2GB - $98
Storage 240GB Sandisk SSD Plus - $68
1TB Western Digital Blue - $49
Case Corsair Carbide Series 88R - $49
Power Supply EVGA 500 Watt - $42
Monitor Nixues VUE24A 1080p 144Hz FreeSync - $251
Total Price $549 on Amazon; $799 with monitor on Amazon

I’ll go in order of presentation for simplicity sake. First up is the selection of the Intel Core i3-6100 processor. This CPU was the most popular offering in the /r/buildapc group and has been the darling of budget gaming builds for a while. It is frequently used because of it $109 price tag, along with dual-core, HyperThreaded performance at 3.7 GHz; giving you plenty of headroom for single threaded applications. Since most games aren’t going to utilize more than four threads, the PC gaming performance will be excellent as well. One frequent suggestion in our thread was the Intel Pentium G4560, a Kaby Lake based part that will sell for ~$70. That would have been my choice but it’s not shipping yet, and I don’t know when it will be.

ASUS' ROG STRIX RX 480 O8G GAMING, getting the most out of Polaris

Subject: Graphics Cards | December 19, 2016 - 01:36 PM |
Tagged: rx 480, asus, ROG STRIX RX 480 O8G GAMING, factory overclocked, DirectCU III, Polaris

ASUS went all out with the design of the ROG STRIX RX 480 O8G GAMING card, almost nothing on this card remains a stock part from cooling to power regulation.  It ships with a GPU clocked at 1310MHz in GAMING mode and 1330MHz in OC mode, [H]ard|OCP reached a stable 1410MHz GPU and 8.8GHz VRAM when manually overclocking.  The card does come at a premium, roughly $50 more than a stock card which makes it more expensive than NVIDIA's GTX 1060.  The bump in frequency helps narrow the performance gap between the two cards, but it doesn't make this RX 480 a clear winner.  Check out the full review to see how it performs in the games which matter to you.
