Kabini is a pretty nifty little chip.  So nifty, AMD is actually producing server grade units for the growing micro-server market.  As readers may or may not remember, AMD bought up SeaMicro last year to get a better grip on the expanding micro-server market.  While there are no official announcements from SeaMicro about offerings utilizing the server-Kabini parts, we can expect there to be sooner as opposed to later.

The Kabini parts (Jaguar + GCN) will be branded Opteron X-series.  So far there are two announced products; one utilizes the onboard graphics portion while the other has the GCN based unit disabled.  The products have a selectable TDP that ranges from 9 watts to 22 watts.  This should allow the vendors to further tailor the chips to their individual solutions.

The X1150 is the GPU-less product with adjustable TDPs ranging from 9 to 17 watts.  It is a native quad core product with 2 MB of L2 cache.  It can be clocked up to 2 GHz, which we assume is that 17 watts range.  The X2150 has an adjustable TDP range from 11 to 22 watts.  The four cores can go to a max speed of 1.9 GHz while the GPU can go from 266 MHz up to a max 600 MHz.

Tagged: gpu, drivers, catalyst 13.6 beta, beta, amd

AMD has released its Catalyst 13.6 beta graphics driver, and it fixes a number of issues under both Windows 8 and Linux. The new beta driver is also compatible with the existing Catalyst 13.5 CAP1 (Catalyst Application Profile) which improves performance of several PC games.

As far as the Windows version of the graphics driver, Catalyst 13.6 adds OpenCL GPU acceleration support to Adobe's Premiere Pro CC software and enables AMD Wireless Display technology on systems with the company's A-Series APUs and either Broadcom or Atheros Wi-Fi chipsets. AMD has also made a couple of tweaks to its Enduro technology, including correctly identifying when a Metro app idles and offloading the corresponding GPU tasks to integrated graphics instead of a discrete card. The new beta driver also resolves an issue with audio dropout over HDMI.

On the Linux side of things, Catalyst 13.6 beta adds support for the following when using AMD's A10, A8, A6, and A4 APUs:

  • Ubuntu 13.04
  • Xserver 1.14
  • GLX_EXT_buffer age

The driver fixes several bugs as well, including resolving black screen and corruption issues under TF2, an issue with OpenGL applications and VSYNC, and UVD playback issues where the taskbar would disappear and/or the system would experience a noticeable performance drop while playing a UVD in XBMC.

You can grab the new beta driver from the AMD website.

The Architectural Deep Dive

AMD officially unveiled their brand new Bobcat architecture to the world at CES 2011.  This was a very important release for AMD in the low power market.  Even though Netbooks were a dying breed at that time, AMD experienced a good uptick in sales due to the good combination of price, performance, and power consumption for the new Brazos platform.  AMD was of the opinion that a single CPU design would not be able to span the power consumption spectrum of CPUs at the time, and so Bobcat was designed to fill that space which existed from 1 watt to 25 watts.  Bobcat never was able to get down to that 1 watt point, but the Z-60 was a 4.5 watt part with two cores and the full 80 Radeon cores.

jag_01.jpg

The Bobcat architecture was produced on TSMC’s 40 nm process.  AMD eschewed the upcoming 32 nm HKMG/SOI process that was being utilized for the upcoming Llano and Bulldozer parts.  In hindsight, this was a good idea.  Yields took a while to improve on GLOBALFOUNDRIES new process, while the existing 40 nm product from TSMC was running at full speed.  AMD was able to provide the market in fairly short order with good quantities of Bobcat based APUs.  The product more than paid for itself, and while not exactly a runaway success that garnered many points of marketshare from Intel, it helped to provide AMD with some stability in the market.  Furthermore, it provided a very good foundation for AMD when it comes to low power parts that are feature rich and offer competitive performance.

The original Brazos update did not happen, instead AMD introduced Brazos 2.0 which was a more process improvement oriented product which featured slightly higher speeds but remained in the same TDP range.  The uptake of this product was limited, and obviously it was a minor refresh to buoy purchases of the aging product.  Competition was coming from low power Ivy Bridge based chips, as well as AMD’s new Trinity products which could reach TDPs of 17 watts.  Brazos and Brazos 2.0 did find a home in low powered, but full sized notebooks that were very inexpensive.  Even heavily leaning Intel based manufacturers like Toshiba released Brazos based products in the sub-$500 market.  The combination of good CPU performance and above average GPU performance made this a strong product in this particular market.  It was so power efficient, small batteries were typically needed, thereby further lowering the cost.

All things must pass, and Brazos is no exception.  Intel has a slew of 22 nm parts that are encroaching on the sub-15 watt territory, ARM partners have quite a few products that are getting pretty decent in terms of overall performance, and the graphics on all of these parts are seeing some significant upgrades.  The 40 nm based Bobcat products are no longer competitive with what the market has to offer.  So at this time we are finally seeing the first Jaguar based products.  Jaguar is not a revolutionary product, but it improves on nearly every aspect of performance and power usage as compared to Bobcat.

A Reference Platform - But not a great one

Believe it or not, AMD claims that the Brazos platform, along with the "Brazos 2.0" update the following year, were the company's most successful mobile platforms in terms of sales and design wins.  When it first took the scene in late 2010, it was going head to head against the likes of Intel's Atom processor and the combination of Atom + NVIDIA ION and winning.  It was sold in mini-ITX motherboard form factors as well as small clamshell notebooks (gasp, dare we say...NETBOOKS?) and though it might not have gotten the universal attention it deserved, it was a great part.

With Kabini (and Temash as well), AMD is making another attempt to pull in some marketshare in the low power, low cost mobile markets.  I have already gone over the details of the mobile platforms that AMD is calling Elite Mobility (Temash) and Mainstream (Kabini) in a previous article that launched today.

12_0.jpg

This article will quickly focus on the real-world performance of the Kabini platform as demonstrated by a reference laptop I received while visiting AMD in Toronto a few weeks ago.  While this design isn't going to be available in retail (and I am somewhat thankful based on the build quality) the key is to look at the performance and power efficiency of the platform itself, not the specific implementation. 

Kabini Architecture Overview

The building blocks of Kabini are four Jaguar x86 cores and 128 Radeon cores colleted in a pair of Compute Units - similar in many ways to the CUs found in the Radeon HD 7000 series discrete GPUs.  Josh has written a very good article that focuses on the completely new architecture that is Jaguar and compared it to other processors including AMD's previous core used in Brazos, the Bobcat core.

2013 Elite Mobility APU - Temash

AMD has a lot to say today.  At an event up in Toronto this month we got to sit down with AMD’s marketing leadership and key engineers to learn about the company’s plans for 2013 mobility processors.  This includes a refreshed high performance APU known as Richland that will replace Trinity as well as two brand new APUs based on Jaguar CPU cores and the GCN architecture for low power platforms. 

Josh has put together an article that details the Jaguar + GCN design of Temash and Kabini and I have also posted some initial performance results of the Kabini reference system AMD handed me in May.  This article will detail the plans that AMD has for each of these three mobile segments, starting with the newest entry, AMD’s Elite Mobility APU platform – Temash.

temash01_0.jpg

The goal of the APU, the combination of traditional x86 processing cores and a discrete style graphics system, was to offer unparalleled performance in smaller and more efficient form factors.  AMD believes that their leadership in the graphics front will offer them a good sized advantage in areas including performance tablets, hybrids and small screen clamshells that may or not be touch enabled.  They are acknowledging though that getting into the smallest tablets (like the Nexus 7) is not on the table quite yet and that content creation desktop replacements are probably outside the scope of Richland. 

 

2013 Elite Mobility APU – Temash

AMD will have the first x86 quad-core SoC design with Temash and AMD thinks it will make a big splash in a relatively new market known as the “high performance” tablet. 

temash02_0.jpg

Temash, built around Jaguar CPU cores and the graphics technology of GCN, will be able to offer fully accelerated video playback with transcode support as well with features like image stabilization and Perfect Picture enabled.  Temash will also be the only SoC to offer support for DX11 graphics and even though some games might not have the ability to show off added effects there are quite a few performance advantages of DX11 over DX10/9.  With more than 100% claimed GPU performance upgrade you’ll be able to drive displays at 2560x1600 for productivity use and even be able to take advantage of wireless display options.

The PS4 and Xbox One Hardware Revealed, Console Makers Have Different Goals

Subject: General Tech | May 22, 2013 - 10:33 PM |
Tagged: xbox one, semi-custom business unit, ps4, microsoft, amd

Microsoft took the wraps off of its upcoming Xbox One console earlier this week, and it is now possible to compare Microsoft and Sony's next-generation hardware.

Prior to the Xbox One launch, Forbes contributor Paul Tassi postulated that Microsoft would be going a different route than Sony with its next Xbox. Specifically, that Microsoft would focus more on media playback and applications rather than purely gaming (unlike Sony, which is doing the opposite). At the time, I found myself agreeing with his sentiment, and now that the console as launched I believe Mr. Tassi was absolutely correct. Microsoft wants the Xbox One to be the center of your living room and the device you use for all of your media (and gaming) needs. The new console integrates the Windows kernel and can do multitasking of applications and media in a Metro-UI like fashion (2/3, 1/3 split screen).

On the other hand, Sony is positioning its console as the best gaming device for the living room, and is focusing on integrating all things gaming with media as more of an afterthought. Like previous PlayStation consoles, it will likely play back media files and Blu-ray movies just fine, but it is a gaming box at its core.

Interestingly, the hardware that both companies have chosen seems to line up nicely with those goals. Both the Xbox One and PS4 are based around a semi-custom AMD APU with eight Jaguar CPU cores, but they have gone in different directions from there.

PlayStation 4 hardware:

As a refresher, Sony's PS4 has the following hardware specifications.

  • CPU:  Eight core AMD “Jaguar” CPU
  • GPU:  AMD GCN GPU with 1152 shader units (in 18 CUs)
  • Memory:  8GB of GDDR5 clocked at 5500MHz
  • HDD:  At least a spindle hard drive
  • Bandwidth:  176 GB/s

Sony has changed directions from the PS3 by going with a simpler design that provides more graphical horsepower and higher system memory bandwidth versus the Xbox One. The PS4 uses a semi-custom AMD chip that has saved Sony a great deal of R&D money while also being easier for developers as it is that much closer to a traditional PC with its x86-64 APU (GDDR5 memory is unusual though). The PS4 is aimed at gamers and Sony's choice of hardware and memory reflects that.

Xbox One hardware:

Xbox One Console.jpg

Microsoft was not as forthcoming as Sony as far as touting specific hardware specifications, but based on the announcement and additional information acquired by AnandTech, the Xbox One features the following hardware:

  • CPU:  Eight core AMD “Jaguar” CPU
  • GPU:  AMD GCN GPU with 768 shader cores (within 12 Compute Units)
  • Memory:  8GB of DDR3 system memory at 2133MHz as well as 32MB of on-chip eSRAM
  • HDD:  500GB
  • DDR3 Memory Bandwidth: 68.3 GB/s
  • eSRAM Memory Bandwidth: 102GB/s

Microsoft took a different approach with the Xbox One. Instead of going for DDR5 like Sony did, Microsoft opted for a hybrid approach that uses a small but high-bandwidth and low latency embedded SRAM on the same chip as the CPU and GPU paired with a larger 8GB of traditional PC DDR3 system memory. This approach is interesting because it gives Microsoft a system that has access to low latency memory at the expense of the higher bandwidth that the PS4 enjoys with its single pool of DDR5 memory. Developers will need to become familiar with the embedded RAM to take full advantage of the latency benefits, however.

These hardware choices work out such that the PS4 has a distinct advantage when it comes to gaming performance. It has more GPU horsepower and high-bandwidth memory for feeding the processor high resolution textures. On the other hand, while Microsoft's console still has a respectable GPU (for a console), it seems to be optimized for lower latency memory access and just enough graphics oomph to enable the company to have a multimedia and home entertainment machine that can run multiple applications simultaneously while also satisfying gamers by giving them a decent graphical upgrade over the Xbox 360 for games. 

This next generation of consoles should be interesting, as will the ensuing "flame wars" between fans. Both Microsoft and Sony have learned from the past (current) generation of consoles and are focusing on what they are good at to differentiate themselves. Microsoft is tapping into its Windows ecosystem of PCs and mobile devices and providing an app machine that the company hopes will be the hub of your living room entertainment needs. Sony, who does not have that expertise or existing infrastructure is also focusing in on what it excels at and that is gaming.

I'm looking forward to seeing how the consoles co-exist and how the market shakes out over 2014 and into the future as the hardware stays the same but software changes. Sony definitely has the hardware advantage to stay in the game longer when it comes to games and graphics, but Microsoft has a box that can do more than games and can find purchase in your media rack even after it is surpassed in gaming graphics quality by PCs and the competition.

What do you think about the split between the Xbox One and PS4's hardware?

JPR Releases Q1 2013 GPU Market Share Numbers, Good News for NVIDIA

Subject: Graphics Cards | May 20, 2013 - 12:54 PM |
Tagged: VIA, Q1 2013, nvidia, jpr, Intel, gpu market share, amd

Market analytics firm Jon Peddie Research recently released estimated market share and GPU shipment numbers from Q1 2013. The report includes information on AMD, NVIDIA, Intel, and Via and covered IGPs, processor graphics, and discrete GPUs included in desktop and mobile systems powered by X86 hardware. The report includes x86 tablets but otherwise does not factor in GPUs used in ARM devices like NVIDIA's Tegra chips. Year over Year, the PC market is down 12.6% and the GPU market declined by 12.9%. It is not all bad news for the PC market and discrete GPU makers, however. GPUs through 2016 are expected to exhibit a compound annual growth rate (CAGR) of 2.6% with as many as 394 million discrete GPUs shipped in 2016 alone.

In Q1 2013, the PC market is down 13.7% versus last quarter (Q4 2012) but the GPU market only declined 3.2%. This discrepency is explained as the result of people adding multiple GPUs to a single PC system, including adding a single discrete card to a system that already has processor graphics or an APU. By the end of Q1 2013, Intel holds 61.8% market share followed by AMD in second place with 20.2% and NVIDIA with 18%. Notably VIA is out of the game with 0.0% market share.

Q12013 Market Share.jpg

In terms of GPU shipments, NVIDIA had a relatively good first quarter of this year with an increase of 7.6% for notebook GPUs and desktop GPU shipments that remained flat. Overall, NVIDIA saw an increase in PC graphics shipments of 3.6%. On the other hand, x86 CPU giant Intel saw desktop and notebook GPUs slip by 3% and 6.3% respectively. Overall, that amounts to PC graphics shipments that fell by 5.3%. In between NVIDIA and Intel, AMD moved 30% more desktop chips (including APUs) versus Q4 2012. Meanwhile, Notebook chips (including APUs) fell by 7.3%. AMD's overall PC graphics shipments fell by 0.3%.

In all, this is decent news for the PC market as it shows that there is still interest in desktop GPUs. The PC market itself is declining and taking the GPU market with it, but it is far from the death of the desktop PC. It is interesting that NVIDIA (which announced Q1'13 revenue of $954.7 million) managed to push more chips while AMD and Intel were on the decline since NVIDIA doesn't have a x86 CPU with integrated graphics. I'm looking forward to seeing where NVIDIA stands as far as the mobile GPU market which does include ARM-powered products.
