Get your brains ready

Just before the weekend, Josh and I got a chance to speak with David Kanter about the AMD Zen architecture and what it might mean for the Ryzen processor due out in less than a month. For those of you not familiar with David and his work, he is an analyst and consultant on processor architectrure and design through Real World Tech while also serving as a writer and analyst for the Microprocessor Report as part of the Linley Group. If you want to see a discussion forum that focuses on architecture at an incredibly detailed level, the Real World Tech forum will have you covered - it's an impressive place to learn.

David was kind enough to spend an hour with us to talk about a recently-made-public report he wrote on Zen. It's definitely a discussion that dives into details most articles and stories on Zen don't broach, so be prepared to do some pausing and Googling phrases and technologies you may not be familiar with. Still, for any technology enthusiast that wants to get an expert's opinion on how Zen compares to Intel Skylake and how Ryzen might fare when its released this year, you won't want to miss it.

As reported by WCCFtech, AMD partner Sapphire has a new 1024 stream processor version of the RX460 listed on their site (Chinese language), and this product reveal of course comes after it became known that RX460 graphics cards had the potential to have their stream processor count unlocked from 896 to 1024 via BIOS update.

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
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

For just $549 I was able to create shopping list of hardware that provides very impressive performance for the investment.

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.

A Holiday Project

A couple of years ago, I performed an experiment around the GeForce GTX 750 Ti graphics card to see if we could upgrade basic OEM, off-the-shelf computers to become competent gaming PCs. The key to this potential upgrade was that the GTX 750 Ti offered a great amount of GPU horsepower (at the time) without the need for an external power connector. Lower power requirements on the GPU meant that even the most basic of OEM power supplies should be able to do the job.

That story was a success, both in terms of the result in gaming performance and the positive feedback it received. Today, I am attempting to do that same thing but with a new class of GPU and a new class of PC games.

The goal for today’s experiment remains pretty much the same: can a low-cost, low-power GeForce GTX 1050 Ti graphics card that also does not require any external power connector offer enough gaming horsepower to upgrade current shipping OEM PCs to "gaming PC" status?

Our target PCs for today come from Dell and ASUS. I went into my local Best Buy just before the Thanksgiving holiday and looked for two machines that varied in price and relative performance.

01.jpg

  Dell Inspiron 3650 ASUS M32CD-B09
Processor Intel Core i3-6100 Intel Core i7-6700
Motherboard Custom Custom
Memory 8GB DDR4 12GB DDR4
Graphics Card Intel HD Graphics 530 Intel HD Graphics 530
Storage 1TB HDD 1TB Hybrid HDD
Case Custom Custom
Power Supply 240 watt 350 watt
OS Windows 10 64-bit Windows 10 64-bit
Total Price $429 (Best Buy) $749 (Best Buy)

The specifications of these two machines are relatively modern for OEM computers. The Dell Inspiron 3650 uses a modest dual-core Core i3-6100 processor with a fixed clock speed of 3.7 GHz. It has a 1TB standard hard drive and a 240 watt power supply. The ASUS M32CD-B09 PC has a quad-core HyperThreaded processor with a 4.0 GHz maximum Turbo clock, a 1TB hybrid hard drive and a 350 watt power supply. Both of the CPUs share the same Intel brand of integrated graphics, the HD Graphics 520. You’ll see in our testing that not only is this integrated GPU unqualified for modern PC gaming, but it also performs quite differently based on the CPU it is paired with.

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

Subject: Graphics Cards | November 14, 2016 - 04:22 PM |
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.
