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.

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.

High Bandwidth Cache

Apart from AMD’s other new architecture due out in 2017, its Zen CPU design, there is no other product that has had as much build up and excitement surrounding it than its Vega GPU architecture. After the world learned that Polaris would be a mainstream-only design that was released as the Radeon RX 480, the focus for enthusiasts came straight to Vega. It’s been on the public facing roadmaps for years and signifies the company’s return to the world of high end GPUs, something they have been missing since the release of the Fury X in mid-2015.

slides-2.jpg

Let’s be clear: today does not mark the release of the Vega GPU or products based on Vega. In reality, we don’t even know enough to make highly educated guesses about the performance without more details on the specific implementations. That being said, the information released by AMD today is interesting and shows that Vega will be much more than simply an increase in shader count over Polaris. It reminds me a lot of the build to the Fiji GPU release, when the information and speculation about how HBM would affect power consumption, form factor and performance flourished. What we can hope for, and what AMD’s goal needs to be, is a cleaner and more consistent product release than how the Fury X turned out.

The Design Goals

AMD began its discussion about Vega last month by talking about the changes in the world of GPUs and how the data sets and workloads have evolved over the last decade. No longer are GPUs only worried about games, but instead they must address profession workloads, enterprise workloads, scientific workloads. Even more interestingly, as we have discussed the gap in CPU performance vs CPU memory bandwidth and the growing gap between them, AMD posits that the gap between memory capacity and GPU performance is a significant hurdle and limiter to performance and expansion. Game installs, professional graphics sets, and compute data sets continue to skyrocket. Game installs now are regularly over 50GB but compute workloads can exceed petabytes. Even as we saw GPU memory capacities increase from Megabytes to Gigabytes, reaching as high as 12GB in high end consumer products, AMD thinks there should be more.

slides-8.jpg

Coming from a company that chose to release a high-end product limited to 4GB of memory in 2015, it’s a noteworthy statement.

slides-11.jpg

The High Bandwidth Cache

Bold enough to claim a direct nomenclature change, Vega 10 will feature a HBM2 based high bandwidth cache (HBC) along with a new memory hierarchy to call it into play. This HBC will be a collection of memory on the GPU package just like we saw on Fiji with the first HBM implementation and will be measured in gigabytes. Why the move to calling it a cache will be covered below. (But can’t we call get behind the removal of the term “frame buffer”?) Interestingly, this HBC doesn’t have to be HBM2 and in fact I was told that you could expect to see other memory systems on lower cost products going forward; cards that integrate this new memory topology with GDDR5X or some equivalent seem assured.

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.

Third annual release

For the past two years, AMD has made a point of releasing one major software update to Radeon users and gamers annually. In 2014 this started with Catalyst Omega, a dramatic jump in performance, compatibility testing and new features were the story. We were told that for the first time in a very long while, and admitting this was the most important aspect to me, AMD was going to focus on building great software with regular and repeated updates. In 2015 we got a rebrand along with the release: Radeon Software Crimson Edition.  AMD totally revamped the visual and user experience of the driver software, bringing into the modern world of style and function. New features and added performance were also the hallmarks of this release, with a stronger promise to produce more frequent drivers to address any performance gaps, stability concerns and to include new features.

For December 2016 and into the new year, AMD is launching the Radeon Software Crimson ReLive Edition driver. While the name might seem silly, it will make sense as we dive into the new features.

While you may have seen the slides leak out through some other sites over the past 48 hours, I thought it was worth offering my input on the release.

Not a performance focused story

The first thing that should be noted with the ReLive Edition is that AMD isn’t making any claims of substantially improved performance. Instead, the Radeon Technologies Group software team is dedicated to continued and frequent iterations that improve performance gradually over time.

slides40.jpg

As you can see in the slide above, AMD is showing modest 4-8% performance gains on the Radeon RX 480 with the Crimson ReLive driver, and even then, its being compared to the launch driver of 16.6.2.  That is significantly lower than the claims made in previous major driver releases. Talking with AMD about this concern, it told us that they don’t foresee any dramatic, single large step increases in performance going forward. The major design changes that were delivered over the last several years, starting with a reconstruction of the CrossFire system thanks to our testing, have been settled. All we should expect going forward is a steady trickle of moderate improvements.

(Obviously, an exception may occur here or there, like with a new game release.)

Radeon ReLive Capture and Streaming Feature

So, what is new? The namesake feature for this driver is the Radeon ReLive application that is built in. ReLive is a capture and streaming tool that will draw obvious comparisons to what NVIDIA has done with GeForce Experience. The ReLive integration is clean and efficient, well designed and seems easy to use in my quick time with it. There are several key capabilities it offers.

First, you can record your gameplay with the press of a hotkey; this includes the ability to record and capture the desktop as well. AMD has included a bevy of settings for your captures to adjust quality, resolution, bitrate, FPS and more.

rev10-table.jpg

ReLive supports resolutions up to 4K30 with the Radeon R9 series of GPUs and up to 1440p30 with the RX 480/470/460. That includes both AVC H.264 and HEVC H.265.

Along with recording is support for background capture, called Instant Replay. This allows the gamer to always record in the background, up to 20 minutes, so you can be sure you capture amazing moments that happen during your latest gaming session. Hitting a hotkey will save the clip permanently to the system.

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

Subject: Graphics Cards | November 14, 2016 - 11:22 AM |
Tagged: video, the last hope, serious sam vr, rx 480, radeon, Polaris, multi-gpu, liquidvr, amd, affinity

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.
