AMD Releases App SDK 3.0 with OpenCL 2.0

Apart from manufacturers with a heavy first-party focus, such as Apple and Nintendo, hardware is useless without developer support. In this case, AMD has updated their App SDK to include support for OpenCL 2.0, with code samples. It also updates the SDK for Windows 10, Carrizo, and Fiji, but it is not entirely clear how.


That said, OpenCL is important to those two products. Fiji has a very high compute throughput compared to any other GPU at the moment, and its memory bandwidth is often even more important for GPGPU workloads. It is also useful for Carrizo, because parallel compute and HSA features are what make it a unique product. AMD has been creating first-party software software and helping popular third-party developers such as Adobe, but a little support to the world at large could bring a killer application or two, especially from the open-source community.

The SDK has been available in pre-release form for quite some time now, but it is finally graduated out of beta. OpenCL 2.0 allows for work to be generated on the GPU, which is especially useful for tasks that vary upon previous results without contacting the CPU again.

The Tiniest Fiji

Way back on June 16th, AMD held a live stream event during E3 to announce a host of new products. In that group was the AMD Radeon R9 Fury X, R9 Fury and the R9 Nano. Of the three, the Nano was the most intriguing to most of the online press as it was the one we knew the least about. AMD promised a full Fiji GPU in a package with a 6-in PCB and a 175 watt TDP. Well today, AMD is, uh, re-announcing (??) the AMD Radeon R9 Nano with more details on specifications, performance and availability.


First, let’s get this out of the way: AMD is making this announcement today because they publicly promised the R9 Nano for August. And with the final days of summer creeping up on them, rather than answer questions about another delay, AMD is instead going the route of a paper launch, but one with a known end date. We will apparently get our samples of the hardware in early September with reviews and the on-sale date following shortly thereafter. (Update: AMD claims the R9 Nano will be on store shelves on September 10th and should have "critical mass" of availability.)

Now let’s get to the details that you are really here for. And rather than start with the marketing spin on the specifications that AMD presented to the media, let’s dive into the gory details right now.

  R9 Nano R9 Fury R9 Fury X GTX 980 Ti TITAN X GTX 980 R9 290X

AMD wasn’t fooling around, the Radeon R9 Nano graphics card does indeed include a full implementation of the Fiji GPU and HBM, including 4096 stream processors, 256 texture units and 64 ROPs. The GPU core clock is rated “up to” 1.0 GHz, nearly the same as the Fury X (1050 MHz), and the only difference that I can see in the specifications on paper is that the Nano is rated at 8.19 TFLOPS of theoretical compute performance while the Fury X is rated at 8.60 TFLOPS.

Thanks to DigiTimes we are getting some information out of Hot Chips about what is coming up from AMD.  As Sebastian just posted we now have a bit more about the R9 Nano and you can bet we will see more in the near future.  They also describe the new HBM developed in partnership with SK Hynix,  4GB of high-bandwidth memory over a 4096-bit interface will offer an impressive 512Gb/s of memory bandwidth.  We also know a bit more about the new A-series APUs which will range up to 12 compute cores, four Excavator based CPUs and eight GCN based GPUs.  They will also be introducing new power saving features called Adaptive Voltage and Frequency Scaling (AVFS) and will support the new H.265 compression standard.  Click on through to DigiTimes or wait for more pictures and documentation to be released from Hot Chips.


"AMD is showcasing its new high-performance accelerated processing unit (APU), codenamed Carrizo, and the new AMD Radeon R9 Fury family of GPUs, codenamed Fiji, at the annual Hot Chips symposium."

Detailed Photos of AMD Radeon R9 Nano Surface (Confirmed)

Subject: Graphics Cards | August 25, 2015 - 02:23 PM |
Tagged: Radeon R9 Nano, radeon, r9 nano, hbm, graphics, gpu, amd

New detailed photos of the upcoming Radeon R9 Nano have surfaced, and Ryan has confirmed with AMD that these are in fact real.


We've seen the outside of the card before, but for the first time we are provided a detailed look under the hood.


The cooler is quite compact and has copper heatpipes for both core and VRM

The R9 Nano is a very small card and it will be powered with a single 8-pin power connector directed toward the back.



Connectivity is provided via three DisplayPort outputs and a single HDMI port

And fans of backplates will need to seek 3rd-party offerings as it looks like this will have a bare PCB around back.


We will keep you updated if any official specifications become available, and of course we'll have complete coverage once the R9 Nano is officially launched!

Manufacturer: Nixeus

Introduction, Specifications, and Packaging


We have reviewed a lot of Variable Refresh Rate displays over the past several years now, and for the most part, these displays have come with some form of price premium attached. Nvidia’s G-Sync tech requires an additional module that adds some cost to the parts list for those displays. AMD took a while to get their FreeSync tech pushed through the scaler makers, and with the added effort needed to implement these new parts, display makers naturally pushed the new features into their higher end displays first. Just look at the specs of these displays:

  • ASUS PG278Q 27in TN 1440P 144Hz G-Sync
  • Acer XB270H 27in TN 1080P 144Hz G-Sync
  • Acer XB280HK 28in TN 4K 60Hz G-Sync
  • Acer XB270HU 27in IPS 1440P 144Hz G-Sync
  • LG 34UM67 34in IPS 25x18 21:9 48-75Hz FreeSync
  • BenQ XL2730Z 27in TN 1440P 40-144Hz FreeSync
  • Acer XG270HU 27in TN 1440P 40-144Hz FreeSync
  • ASUS MG279Q 27in IPS 1440P 144Hz FreeSync (35-90Hz)

Most of the reviewed VRR panels are 1440P or higher, and the only 1080P display currently runs $500. This unfortunately leaves VRR technology at a price point that is simply out of reach of gamers unable to drop half a grand on a display. What we need was a good 1080P display with a *full* VRR range. Bonus points to high refresh rates and in the case of a FreeSync display, a minimum refresh rate low enough that a typical game will not run below it. This shouldn’t be too hard since 1080P is not that demanding on even lower cost hardware these days. Who was up to this challenge?


Nixeus has answered this call with their new Nixeus Vue display. This is a 24” 1080P 144Hz FreeSync display with a VRR bottom limit of 30 FPS. It comes in two models, distinguished by a trailing letter in the model. The NX-VUE24B contains a ‘base’ model stand with only tilt support, while the NX-VUE24A contains a ‘premium’ stand with full height, rotation, and tilt support.

Does the $330-350 dollar Nixues Vue 24" FreeSync monitor fit the bill?

Report: Leaked Slide From AMD Gives Glimpse of R9 Nano Performance

Subject: Graphics Cards | August 24, 2015 - 02:37 PM |
Tagged: rumor, report, Radeon R9 Nano, R9 290X, leak, hot chips, hbm, amd

A report from German-language tech site Golem contains what appears to be a slide leaked from AMD's GPU presentation at Hot Chips in Cupertino, and the results paint a very efficient picture of the upcoming Radeon R9 Nano GPU.


The spelling of "performance" doesn't mean this is fake, does it?

While only managing 3 FPS better than the Radeon R9 290X in this particular benchmark, this result was achieved with 1.9x the performance per watt of the baseline 290X in the test. The article speculates on the possible clock speed of the R9 Nano based on the relative performance, and estimates 850 MHz (which is of course up for debate as no official specs are known).

The most compelling part of the result has to be the ability of the Nano to match or exceed the R9 290X in performance, while only requiring a single 8-pin PCIe connector and needing an average of only 175 watts. With a mini-ITX friendly 15 cm board (5.9 inches) this could be one of the more compelling options for a mini gaming rig going forward.

We have a lot of questions that have yet to be answered of course, including the actual speed of both core and HBM, and just how quiet this air-cooled card might be under load. We shouldn't have to wait much longer!


GPU Market Share: NVIDIA Gains in Shrinking Add-in Board Market

While we reported recently on the decline of overall GPU shipments, a new report out of John Peddie Research covers the add-in board segment to give us a look at the desktop graphics card market. So how are the big two (sorry Matrox) doing?

GPU Supplier Market Share This Quarter Market Share Last Quarter Market Share Last Year
AMD 18.0% 22.5% 37.9%
Matrox 0.00% 0.1% 0.1%
NVIDIA 81.9% 77.4% 62.0%

The big news is of course a drop in market share for AMD of 4.5% quarter-to-quarter, and down to just 18% from 37.9% last year. There will be many opinions as to why their share has been dropping in the last year, but it certainly didn't help that the 300-series GPUs are rebrands of 200-series, and the new Fury cards have had very limited availability so far.


The graph from Mercury Research illustrates what is almost a mirror image, with NVIDIA gaining 20% as AMD lost 20%, for a 40% swing in overall share. Ouch. Meanwhile (not pictured) Matrox didn't have a statistically meaningful quarter but still manage to appear on the JPR report with 0.1% market share (somehow) last quarter.

The desktop market isn't actually suffering quite as much as the overall PC market, and specifically the enthusiast market.

"The AIB market has benefited from the enthusiast segment PC growth, which has been partially fueled by recent introductions of exciting new powerful (GPUs). The demand for high-end PCs and associated hardware from the enthusiast and overclocking segments has bucked the downward trend and given AIB vendors a needed prospect to offset declining sales in the mainstream consumer space."

But not all is well considering overall the add-in board attach rate with desktops "has declined from a high of 63% in Q1 2008 to 37% this quarter". This is indicative of the overall trend toward integrated GPUs in the industry with AMD APUs and Intel processor graphics, as illustrated by this graphic from the report.


The year-to-year numbers show an overall drop of 18.8%, and even with their dominant 81.9% market share NVIDIA has still seen their shipments decrease by 12% this quarter. These trends seem to indicate a gloomy future for discrete graphics in the coming years, but for now we in the enthusiast community will continue to keep it afloat. It would certainly be nice to see some gains from AMD soon to keep things interesting, which might help lower prices down from their lofty $400 - $600 mark for flagship cards at the moment.

AMD Radeon R9 Fury Unlocked as Fury X, Overclocked to 1 GHz HBM

Subject: Graphics Cards | August 12, 2015 - 05:29 PM |
Tagged: STRIX R9 Fury, Radeon R9 Fury, overclocking, oc, LN2, hbm, fury x, asus, amd

What happens when you unlock an AMD Fury to have the Compute Units of a Fury X, and then overclock the snot out of it using LN2? User Xtreme Addict in the HWBot forums has created a comprehensive guide to do just this, and the results are incredible.


Not for the faint of heart (image credit: Xtreme Addict)

"The steps include unlocking the Compute Units to enable Fury X grade performance, enabling the hotwire soldering pads, a 0.95v Rail mod, and of course the trimpot/hotwire VGPU, VMEM, VPLL (VDDCI) mods.

The result? A GPU frequency of 1450 MHz and HBM frequency of 1000 MHz. For the HBM that's a 100% overclock."

Beginning with a stock ASUS R9 Fury STRIX card Xtreme Addict performed some surgery to fully unlock the voltage, and unlocked the Compute Units using a tool from this thread.


The results? Staggering. HBM at 1000 MHz is double the rate of the stock Fury X, and a GPU core of 1450 MHz is a 400 MHz increase. So what kind of performance did this heavily overclocked card achieve?

"The performance goes up from 6237 points at default to 6756 after unlocking the CUs, then 8121 points after overclock on air cooling, to eventually end up at 9634 points when fully unleashed with liquid nitrogen."

Apparently they were able to push the card even further, ending up with a whopping 10033 score in 3DMark Fire Strike Extreme.


While this method is far too extreme for 99% of enthusiasts, the idea of unlocking a retail Fury to the level of a Fury X through software/BIOS mods is much more accessible, as is the possibility of reaching much higher clocks through advanced cooling methods.

Unfortunately, if reading through this makes you want to run out and grab one of these STRIX cards availability is still limited. Hopefully supply catches up to demand in the near future.
