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 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.

Ryan was not the only one at AMD's Radeon Instinct briefing, covering their shot across NVIDIA's HPC products.  The Tech Report just released their coverage of the event and the tidbits which AMD provided about the MI25, MI8 and MI6; no relation to a certain British governmental department.   They focus a bit more on the technologies incorporated into GEMM and point out that AMD's top is not matched by an NVIDIA product, the GP100 GPU does not come as an add-in card.  Pop by to see what else they had to say.

"Thus far, Nvidia has enjoyed a dominant position in the burgeoning world of machine learning with its Tesla accelerators and CUDA-powered software platforms. AMD thinks it can fight back with its open-source ROCm HPC platform, the MIOpen software libraries, and Radeon Instinct accelerators. We examine how these new pieces of AMD's machine-learning puzzle fit together."

AMD Enters Machine Learning Game with Radeon Instinct Products

NVIDIA has been diving in to the world of machine learning for quite a while, positioning themselves and their GPUs at the forefront on artificial intelligence and neural net development. Though the strategies are still filling out, I have seen products like the DIGITS DevBox place a stake in the ground of neural net training and platforms like Drive PX to perform inference tasks on those neural nets in self-driving cars. Until today AMD has remained mostly quiet on its plans to enter and address this growing and complex market, instead depending on the compute prowess of its latest Polaris and Fiji GPUs to make a general statement on their own.

instinct-18.jpg

The new Radeon Instinct brand of accelerators based on current and upcoming GPU architectures will combine with an open-source approach to software and present researchers and implementers with another option for machine learning tasks.

The statistics and requirements that come along with the machine learning evolution in the compute space are mind boggling. More than 2.5 quintillion bytes of data are generated daily and stored on phones, PCs and servers, both on-site and through a cloud infrastructure. That includes 500 million tweets, 4 million hours of YouTube video, 6 billion google searches and 205 billion emails.

instinct-6.jpg

Machine intelligence is going to allow software developers to address some of the most important areas of computing for the next decade. Automated cars depend on deep learning to train, medical fields can utilize this compute capability to more accurately and expeditiously diagnose and find cures to cancer, security systems can use neural nets to locate potential and current risk areas before they affect consumers; there are more uses for this kind of network and capability than we can imagine.

Serious Sam VR: The Last Hope scales with multi-GPU

Subject: Graphics Cards | November 14, 2016 - 11:22 AM |

While VR excitement might have cooled slightly in the enthusiast community, there continues to be innovation and software releases on both the Oculus Rift and HTC Vive that are bringing me back to what I think we believe to be part of the future of PC gaming. Serious Sam VR: The Last Hope was announced at E3 this year and is now available as an early access game on Steam. It is a dual wielding shooter that combines the enemies of the previous games along with the crazy weapons that made the series iconic.

ssvrscreen1.jpg

And hey, there is something awesome about using a missile launcher that takes up half the screen.

One interesting technology addition to the game is use of AMD LiquidVR affinity multi-GPU. A Croteam developer recently posted a blog on the GPUOpen.com site talking about the implementation.

We wanted to add LiquidVR Affinity Multi-GPU rendering support to our engine because two GPUs can render the two eye views in almost half the time compared to a single GPU and this would greatly reduce our GPU bottlenecks. Affinity MGPU can either be done in one pass or with a separate pass for each eye, in which case we reap the GPU side benefits while the CPU workload stays the same.

ssvrscreen2.jpg

We needed about a week to modify all shaders and to make sure that correct data is set for each eye. Single pass rendering with Affinity Multi-GPU gave us a huge speed improvement on both CPU and GPU from our original VR implementation. In the end, it took us less time to do single pass rendering correctly than it took us to fix all the problems caused by multi pass multi-GPU rendering.

After the interest in the Deus Ex multi-GPU scaling video I thought I would see if the Serious Sam implementation was actually beneficial to gamers.

  • Test System
  • Core i7-5960X
  • X99 MB + 16GB DDR4
  • AMD Radeon RX 480 8GB
  • Driver: 16.10.2

The test was simple: I found that a single RX 480 could run the game at Medium settings perfectly well, but could it be playable on High with multi-GPU? By adding in a second Radeon RX 480 I was able to bring the performance up by 55% or so, making the VR experience nearly flawless.

ssvr-1.png

ssvr-2.png

It's not perfect scaling, but the benefits of multi-GPU for VR, when properly implemented, are obvious. As more games and experiences are released that require higher compute capability or have in-game settings that allow for better image quality, the ability to scale across GPUs will be a welcome addition to the ecosystem.

AMD Releases New Generation of Radeon Pro Workstation Cards

Subject: Graphics Cards | November 7, 2016 - 09:32 AM |
Tagged: WX 7100, WX 5100, WX 4100, workstation, radeon pro, radeon, quadro, Polaris, amd

The professional card market is a lucrative one.  For many years NVIDIA has had a near strangle-hold on it with their Quadro series of cards.  Offering features and extended support far beyond that of their regular desktop cards, Quadros became the go-to cards for many professional applications.  AMD has not been overlooking this area though and have had a history of professional cards that have also included features and support not seen in the standard desktop arena.  AMD has slowly been chipping away at Quadro’s marketshare and they hope that today’s announcement will help further that particular goal.

It has now been around five months since the initial release of the Polaris based graphics cards from AMD.  Featuring the 4th generation GCN architecture and fabricated on Samsung’s latest 14nm process, the RX 4x0 series of chips have proven to be a popular option in the sub-$250 range of cards.  These products may not have been the slam-dunk that many were hoping from AMD, they have kept the company competitive in terms of power and performance.  AMD has also seen a positive impact from the sales of these products on the overall bottom line.

Today AMD is announcing three new professional cards based on the latest Polaris based GPUs.  These range in power and performance from a sub 50 watt part up to a very reasonable 130 watts.  These currently do not feature the SSD that was shown off earlier this year.

wx4100.jpg

The lowest end offering is the Radeon Pro WX 4100.  This is a low profile, single slot card that consumes less than 50 watts.  It features 1024 stream units, which is greater than that of the desktop RX 460’s 896.  The WX 4100 features 2.4 TFLOPS of performance while the RX 460 is at 2.2 TFLOPS.  AMD did not specify exactly what chips were used in the professional cards, but the assumption here is that this one is a fully enabled Polaris 11.

The power consumption of this card is probably the most impressive part.  Also of great interest is the DP 1.4 support and the four outputs.  Finally the card supports 5K monitors at 60 Hz.  This is a small, quiet, and cool running part that features the entire AMD Radeon Enterprise software support of the professional market.

wx5100.jpg

The next card up is the Pro WX 5100.  This features a sub 75 watt GPU that runs 1792 stream units.  We guess that this chip is a cut down Polaris 10.  On the desktop side it is similar to the RX 470, but that particular card features more stream units and a faster clockspeed.  The RX 470 is rated at 4.9 TFLOPS while the WX 5100 is at 3.9 TFLOPS.  Fewer stream units and a lower clockspeed allow it to hit that sub-75 watt figure.

It supports the same number of outputs as the 4100, but they are full sized DP.  The card is full sized but still only single slot due to the very conservative TDP.

wx7100.jpg

The final card is the WX 7100.  This is based on the fully enabled Polaris 10 GPU and is physically similar to the RX 480.  They both feature 2304 stream units, but the WX 7100 is slightly clocked down from the RX 480 as it features 5.7 TFLOPS of performance vs. 5.8 TFLOPS.  The card is rated below 130 watts TDP which is about 20 watts lower than a standard RX 480.  AMD did not explain to us how they were able to lower the TDP of this card, but it could be simple binning of parts or an upcoming revision of Polaris 10 to improve thermals.

This card is again full sized but single slot.  It features the same 4 DP connectors as the WX 5100 and the full monitor support that the 1.4 standard entails.

These products will see initial availability for this month.  Plans may of course change and they will be introduced slightly later.  Currently the 7100 and 4100 are expected after the 10th while the 5100 should show up on the 18th.

software.jpg

AMD is also releasing the Radeon Pro Software.  This is essentially their professional driver development that improves upon features, stability, and performance over time.  AMD aims to release new drivers for this market every 4th Thursday each quarter.

software_2.jpg

This is certainly an important area for AMD to address with their new cards and this updated software scheme.  NVIDIA has made a pretty penny over the years from their Quadro stack due to the extremely robust margins for these cards.  The latest generation of AMD Radeon Pro WX cards look to stack up favorably against the latest products from NVIDIA.

The WX 7100 will come in at a $799 price point, while the WX 5100 and WX 4100 will hit $499 and $399 respectively.

AMD Celebrates Anniversary of Radeon Technologies Group

Subject: General Tech, Graphics Cards | September 14, 2016 - 09:55 PM |
Tagged: rtg, radeon technologies group, Polaris, crimson, amd radeon, amd

It has now been a year since the formation of AMD’s Radeon Technologies Group and the graphics driven division has proven itself rather successful. Looking back with hindsight, AMD's new graphics division has enjoyed several wins with new products and advancements in driver support reclaiming market share from NVIDIA and new initiatives advancing VR, HDR, and open source visual effects.

Radeon Technologies Group.jpg

Specifically, the Radeon Technologies Group, led by Raja Koduri, has managed to launch its new "Polaris" graphics architecture based on a 14nm FinFET process with the RX 400 series for consumers and the Radeon Pro Duo, Radeon Pro WX series, and Radeon Pro SSG (Solid State Graphics) for professionals. The company asl hit a milestone on FreeSync monitor design wins with a total of 101 displays launched to date.

Along with actual hardware, the graphics division has shaken up branding by rolling out new driver software under the Radeon Crimson Edition brand (with 21 driver releases since release) and dropping FirePro in favor of carrying over the Radeon name to create new Radeon Pro branding for its professional series of graphics cards. Driver support has also been enhanced on Linux and the AMDGPU-Pro driver works for RX 400 series.

Further, the Radeon Technologies Group launched its GPUOpen initiative back in December to foster the creation and advancement of free and open source visual effects and productivity code that developers are free to download, modify, and share.

Speaking of market share, AMD has managed to claw back some discrete GPU market share from a lowly 18% of GPUs in Q2 2015 to nearly 30% last quarter (Q2'16). That is a very respectable jump in just a year's time especially against NVIDIA's successful Pascal launches helped both by the price/performance of RX 400 as well as much needed focus on improving driver quality and timeliness of releases. 

Where does this leave AMD and its RTG? Honestly, the graphics division is in a much better place than it was last year and it is in a decent position to survive and make a difference. There are still many unknowns and just as AMD's processor division is dependent on a successful Zen release, the graphics division will need Vega to be a hit in order for AMD to get wins on the high end and compete with NVIDIA on the flagship and performance fronts. They will further need Vega to update their professional series of cards many of which are still using the company's Fiji architecture which is not as power efficient as Pascal or future Volta (the competition).

With that said, the team had solid wins since their formation and are gearing up for the future. According to the announcement, the Radeon Technologies Group will be focusing on pushing virtual reality (VR) and HDR (high dynamic range) in gaming by working with developers, improving drivers, adding to their GPUOpen software collection, and launching new products.

From the press release:

"We’re passionate about perfecting pixels and delivering an unrivaled gaming experience for our community, and uncompromising power and creative freedom for developers and content creators. And if you think our first year was exciting, wait until you see what RTG has lined up for the future."

In the near future, Raja Koduri told Venture Beat to expect VR backpacks to be on show at CES in January and to look out for mobile Polaris graphics cards. Also, Radeon Crimson Edition may be incorporating features from recently acquired startup HiAlgo who developed software to dynamically monitor gameplay and adjust the resolution to maintain maximum frame rates and prevent overheating during long game sessions. One of their techniques called HiAlgo Switch would allow gamers to switch from full to half resolution (and back again) at the press of a hot-key button so as to keep FPS high if a gamer anticipates they are about to enter a demanding area that would normally result in low frame rates. While these techniques are not very important for desktop gaming (especially the CPU/GPU limiter to prevent overheating), all three would come in handy for mobile gamers using laptops with discrete cards or especially APUs.

I am looking forward to seeing where Raja and the RTG team go from here and what they have in store for AMD graphics.

AMD Details the RX 470 and RX 460 Graphics Cards, Coming in August

Subject: Graphics Cards | July 29, 2016 - 01:09 AM |
Tagged: rx 470, rx 460, radeon, polaris 11, polaris 10, Polaris, amd

We know pretty much all there is to know about AMD's new Polaris architecture thanks to our Radeon RX 480 review, but AMD is taking the covers off of the lower priced, lower performance products based on the same architecture tonight. We previously covered AMD's launch event in Australia where the company officially introduced the Polaris 10 RX 470 and Polaris 11 RX 460 and talked about the broader specifications. Now, we have a bit more information to share on specifics and release dates. Specifically, AMD's RX 470 will launch on Thursday, August 4th and the RX 460 will launch on the following Monday, August 8th.

slides-25.jpg

First up is the Radeon RX 470, based on the same Polaris 10 GPU as the RX 480, but with some CUs disabled to lower performance and increase yields. 

slides-15.jpg

This card is aimed at 1080p gaming at top quality settings with AA enabled at 60 FPS. Obviously that is a very vague statement, but it gives you an idea of what price point and target segment the RX 470 is going after.

slides-17.jpg

The only comparison we have from AMD pits the upcoming RX 470 against the R9 270, where Polaris offers a range from 1.5x to 2.4x improvement in a handful of titles, which include DX12 and Vulkan enabled games, of course.

slides-28.jpg

From a specifications stand point, the RX 470 will include 2048 stream processors running at a base clock of 926 MHz and a rated boost frequency of 1206 MHz. That gives us 4.9 TFLOPS of theoretical peak performance to pair with a 6.6 Gbps memory interface capable of 211 GB/s of peak bandwidth. With a 4GB frame buffer and a 120 watt TDP, the RX 470 should offer some compelling performance in the ~$150 price segment (this price is just a guess on my part... though yields should be better – they can salvage RX 480s – and partners being able to use memory chips that do not have to hit 8 Gbps should help to lower costs).

slides-19.jpg

Going down another step to the Radeon RX 460, AMD is targeting this card at 1080p resolutions at "high" image quality settings. The obvious game categories here are eSports titles like MOBAs, CS: Go, Overwatch, etc.

slides-21.jpg

Again, AMD provides a comparison to other AMD hardware: in this case the R7 260X. You'll find a 1.2x to 1.3x performance improvements in these types of titles. Clearly we want to know where the performance rests against the GeForce line but this comparison seems somewhat modest. 

slides-29.jpg

Based on the smaller Polaris 11 GPU, which is a new chip that we have not seen before, the RX 460 features up to 2.2 TFLOPS of computing capability with 896 stream processors (14 CUs enabled out of 16 total in full Polaris 11) running between 1090 MHz and 1200 MHz. The memory system is actually running faster on the RX 460 than the RX 470, though with half the memory bus width at 128-bits. The TDP of this card is sub-75 watts and thus we should find cards that don't require any kind of external power. The RX 460 GPU will be used in desktop cards as well as notebooks (though with lower TDPs and clocks).

The chart below outlines the comparison between the three known Polaris graphics processors.

  RX 480 RX 470 RX 460
Stream Processors 2304 2048 896
Compute Units 36 32 14
TMUs 144 128 56
ROPs 32 32 16
GPU Clock (Base) 1120 MHz 926 MHz 1090 MHz
GPU Clock (Boost) 1266 MHz 1206 MHz 1200 MHz
Memory 4 or 8 GB GDDR5 4 or 8 GB GDDR5 2 or 4 GB GDDR5
Memory Bus 256-bit 256-bit 128-bit
Memory Bandwidth 256 GB/s 211 GB/s 112 GB/s
TDP 150W 120W <75W
GPU Polaris 10 Polaris 10 Polaris 11

There is still much to learn about these new products, most importantly, prices. AMD is still shying away from telling us that important data point. The RX 470 will be on sale and will have reviews on August 4th, with the RX 460 following that on August 8th, so we'll have details and costs in our hands very soon.

It is not clear how many or what kinds of cards we can expect to see on the August 4th and August 8th release days though it would stand to reason that they will be mostly based upon reference designs especially for the RX 460 (though Gamer's Nexus did spot a dual fan Sapphire card).. With that said, we may see custom cooled RX 470 graphics cards because while AMD does technically have a reference design with blower style cooler the company expects most if not all of its partners to go their own direction with this board including their own single and dual fan coolers.

For gamers looking to buy into the truly budget card segment, stay tuned just a little longer!
