Today during AMD's live stream event celebrating 30 years of graphics and gaming, the company spent a bit of time announcing and teasing a new graphics card, the Radeon R9 285X and R9 285. Likely based on the Tonga GPU die, the specifications haven't been confirmed but most believe that the chip will feature 2048 stream processors, 128 texture units, 32 ROPs and a 256-bit memory bus.

In a move to help donate to the Child's Play charity, AMD currently has an AMD Radeon R9 285 on Ebay. It lists an ASUS built Strix-style cooled retail card, with 2GB of memory being the only specification that is visible on the box.

The R9 285X and R9 285 will replace the R9 280X and R9 280 more than likely and we should see these shipping and available in very early September.

UPDATE: AMD showed specifications of the Radeon R9 285 during the live stream.

For those of you with eyes as bad as mine, here are the finer points:

  • 1,792 Stream Processors
  • 918 MHz GPU Clock
  • 3.29 TFLOPS peak performance
  • 112 Texture units
  • 32 ROPs
  • 2GB GDDR5
  • 256-bit memory bus
  • 5.5 GHz memory clock
  • 2x 6-pin power connectors
  • 190 watt TDP
  • $249 MSRP
  • Release date: September 2nd

These Tonga GPU specifications are VERY similar to that of the R9 280: 1792 stream units, 112 texture units, etc. However, the R9 280 had a wider memory bus (384-bit) but runs at 500 MHz lower effective frequency. Clock speeds on Tonga look like they are just slightly lower as well. Maybe most interesting is the frame buffer size drop from 3GB to 2GB.

That's all we have for now, but I expect we'll have our samples in very soon and expect a full review shortly!

UPDATE 2: Apparently AMD hasn't said anything about the Radeon R9 285X, so for the time being, that still falls under the "rumor" category. I'm sure we'll know more soon though.

HP Readies 14" Notebook Powered By AMD Mullins APU

Subject: General Tech, Systems | August 22, 2014 - 02:32 PM |
Tagged: Windows 8.1, notebook, netbook, Mullins, hp, amd, A4 Micro-6400T

According to internal support documents unearthed by Liliputing, HP is preparing to launch a new budget notebook powered by an AMD "Mullins" APU. The HP 14Z-z000, which will also be known as the HP Stream Notebook, is a 14-inch netbook running the full version of Windows 8.1 weighing 3.9 pounds and measuring 13.5" x 9.5" x 0.7". The Stream will be the second device from HP to utilize AMD's latest mobile "Mullins" APUs (the first device being the $250 10-inch Pavilion 10z).

Alleged HP Stream 14-Inch Notebook.jpg

HP's Stream notebook is a traditional laptop-style design that uses a hinged 1366x768 display, full keyboard, trackpad, 720p webcam, and four Beats Audio speakers. However, internally, the Stream resembles tablet hardware more than laptops because the internal storage, processor, and RAM are not upgradeable. Physical IO ports include one HDMI, one USB 3.0, two USB 2.0, and a SDXC card slot.

Internally, the Stream uses an AMD A4 Micro-6400T processor, 2GB of RAM, either 32GB or 64GB of eMMC storage, a 802.11n+Bluetooh 4.0 radio, and a 32Whr battery. The A4 Micro-6400T processor is the interesting bit here, as it is a solution that has not seen many design wins yet. This APU is part of AMD's "Mullins" family which is the successor to Temash. The 28nm HKMG chip features four Puma+ cores (improved Jaguar) clocked at 1.6GHz, a 128 core GCN GPU clocked at 350MHz, 2MB of L2 cache, and support for DDR3L 1333MHz memory. The Micro-6400T is rated at 2.8W SDP (Scenario Design Power) and 4.5W TDP (Thermal Design Power). Further, it features TrustZone technology and new power management features that allow it to boost (or downclock) clockspeeds in certain situations with an emphasis on extending battery life.

HP is bundling the Stream with 100GB of Microsoft OneDrive which is free for two years.

The Stream should be available shortly with a starting price of $199 from HP. I do wish HP was less stingy with batteries in these low power systems (here's looking at you HP X360), but this Mullins-powered netbook should at least be performance competitive with existing Bay Trail based notebooks according to these Mullins APU benchmarks. I would like to see how this midrange APU (The Micro 6700T is actually the top end Mullins) stacks up to the newer Z3770 Atom.

Are you interested in this new generation of budget notebooks?

Introduction, Specifications and Packaging

Introduction:

AMD has been branching their brand out past CPUs for nearly a decade now. Back in 2006, AMD acquired ATI, and their video card branch has been highly competitive ever since. Then in 2011, AMD entered the RAM market by partnering with Patriot and VisionTek. That partnership appears to have been fruitful, along with some additional help in the form of RAMDisk software through an additional partnership with Dataram, as more recently a highly competitive Gamer Series of that RAM was launched. So, CPU's - check, GPU's - check, RAM - check. What's next? Solid State Drives? Sure, why not!

Behold the AMD Radeon R7 SSD!

Ok, so the naming might be a bit confusing for those familiar with AMD's video card line of the same name, so you'll have to be sure to include 'SSD' in your searches if you are looking for one of these on the market. Just like AMD handled the RAM, they have again chosen to partner with another company in the creation of a new product:

lineup.png

...and this time that choice was OCZ. As you can see above, the Radeon R7 is a gamer-oriented SSD, which sits right in between the Vertex 460 and the Vector 150 in OCZ's product lineup. The expectation is performance similar to the Vector, but with a slightly lower warranty and GB/day rating. We also see the inclusion of the lower cost 'advanced' Toshiba A19nm MLC flash, which should help with pricing and get this new SSD into the hands of even more gamers.

AMD squeezes 240GB onto a Radeon

We have seen the Barefoot 3 controller that AMD used in their first SSD before in OCZ's Vector 150, but not exactly like this.  The controller has been optimized to work with Toshiba's 19nm and is clocked slightly higher than the Vertex, though AMD will not say by how much.  That may account for the reduction in daily writes to 30GB/day and the warranty period to 4 years but as it is OCZ that is handling the warranty it is hard to determine the exact reasoning at this point.  On the plus side the MSRP is also reduced by $28 to $164 which still falls short of reaching the magic $0.50/GB mark.  The Tech Report tested the 240GB model here, as with other SSDs you can expect the 120GB to be slightly slower and the 480GB model to perform slightly faster.

"AMD is getting into the storage business. The Radeon R7 SSD combines OCZ's Barefoot 3 controller with Toshiba's 19-nm MLC NAND, custom firmware, and a snazzy new sticker. We take a quick look to see what's what."

Khronos Announces "Next" OpenGL & Releases OpenGL 4.5

Subject: General Tech, Graphics Cards, Shows and Expos | August 15, 2014 - 05:33 PM |
Tagged: siggraph 2014, Siggraph, OpenGL Next, opengl 4.5, opengl, nvidia, Mantle, Khronos, Intel, DirectX 12, amd

Let's be clear: there are two stories here. The first is the release of OpenGL 4.5 and the second is the announcement of the "Next Generation OpenGL Initiative". They both occur on the same press release, but they are two, different statements.

OpenGL 4.5 Released

OpenGL 4.5 expands the core specification with a few extensions. Compatible hardware, with OpenGL 4.5 drivers, will be guaranteed to support these. This includes features like direct_state_access, which allows accessing objects in a context without binding to it, and support of OpenGL ES3.1 features that are traditionally missing from OpenGL 4, which allows easier porting of OpenGL ES3.1 applications to OpenGL.

opengl_logo.jpg

It also adds a few new extensions as an option:

ARB_pipeline_statistics_query lets a developer ask the GPU what it has been doing. This could be useful for "profiling" an application (list completed work to identify optimization points).

ARB_sparse_buffer allows developers to perform calculations on pieces of generic buffers, without loading it all into memory. This is similar to ARB_sparse_textures... except that those are for textures. Buffers are useful for things like vertex data (and so forth).

ARB_transform_feedback_overflow_query is apparently designed to let developers choose whether or not to draw objects based on whether the buffer is overflowed. I might be wrong, but it seems like this would be useful for deciding whether or not to draw objects generated by geometry shaders.

KHR_blend_equation_advanced allows new blending equations between objects. If you use Photoshop, this would be "multiply", "screen", "darken", "lighten", "difference", and so forth. On NVIDIA's side, this will be directly supported on Maxwell and Tegra K1 (and later). Fermi and Kepler will support the functionality, but the driver will perform the calculations with shaders. AMD has yet to comment, as far as I can tell.

If you are a developer, NVIDIA has launched 340.65 (340.23.01 for Linux) beta drivers for developers. If you are not looking to create OpenGL 4.5 applications, do not get this driver. You really should not have any use for it, at all.

Next Generation OpenGL Initiative Announced

The Khronos Group has also announced "a call for participation" to outline a new specification for graphics and compute. They want it to allow developers explicit control over CPU and GPU tasks, be multithreaded, have minimal overhead, have a common shader language, and "rigorous conformance testing". This sounds a lot like the design goals of Mantle (and what we know of DirectX 12).

amd-mantle-queues.jpg

And really, from what I hear and understand, that is what OpenGL needs at this point. Graphics cards look nothing like they did a decade ago (or over two decades ago). They each have very similar interfaces and data structures, even if their fundamental architectures vary greatly. If we can draw a line in the sand, legacy APIs can be supported but not optimized heavily by the drivers. After a short time, available performance for legacy applications would be so high that it wouldn't matter, as long as they continue to run.

Add to it, next-generation drivers should be significantly easier to develop, considering the reduced error checking (and other responsibilities). As I said on Intel's DirectX 12 story, it is still unclear whether it will lead to enough performance increase to make most optimizations, such as those which increase workload or developer effort in exchange for queuing fewer GPU commands, unnecessary. We will need to wait for game developers to use it for a bit before we know.

Prying OpenGL to slip a little Mantle inside

Subject: General Tech | August 15, 2014 - 10:09 AM |
Tagged: amd, Mantle, opengl, OpenGL Next

Along with his announcements about FreeSync, Richard Huddy also discussed OpenGL Next and its relationship with Mantle and the role it played in DirectX 12's development.  AMD has given Chronos Group, the developers of OpenGL, complete access to Mantle to help them integrate it into future versions of the API starting with OpenGL Next.  He also discussed the advantages of Mantle over DirectX, citing AMD's ability to update it much more frequently than Intel has done with DX.  With over 75 developers working on titles that take advantage of Mantle the interest is definitely there but it is uncertain if devs will actually benefit from an API which updates at a pace faster than a game can be developed.  Read on at The Tech Report.

Richard Huddy Discusses FreeSync Availability Timeframes

Subject: General Tech, Displays | August 14, 2014 - 01:59 PM |
Tagged: amd, freesync, g-sync, Siggraph, siggraph 2014

At SIGGRAPH, Richard Huddy of AMD announced the release windows of FreeSync, their adaptive refresh rate technology, to The Tech Report. Compatible monitors will begin sampling "as early as" September. Actual products are expected to ship to consumers in early 2015. Apparently, more than one display vendor is working on support, although names and vendor-specific release windows are unannounced.

amd-freesync1.jpg

As for cost of implementation, Richard Huddy believes that the added cost should be no more than $10-20 USD (to the manufacturer). Of course, the final price to end-users cannot be derived from this - that depends on how quickly the display vendor expects to sell product, profit margins, their willingness to push new technology, competition, and so forth.

If you want to take full advantage of FreeSync, you will need a compatible GPU (look for "gaming" support in AMD's official FreeSync compatibility list). All future AMD GPUs are expected to support the technology.
