AMD has certainly gone about doing things in a slightly different manner than we are used to. Today they announced their two latest APUs which will begin shipping in the first half of 2015. These APUs are running at AMD and are being validated as we speak. AMD did not release many details on these products, but what we do know is pretty interesting.
Carrizo is based on the latest iteration of AMD’s CPU technology. Excavator is the codename for these latest CPU cores, and they promise to be smaller and more efficient than the previous Steamroller core which powers the latest Kaveri based APUs. Carrizo-L is the lower power variant which will be based on the Puma+ core. The current Beema APU is based on the Puma architecture.
Roadmaps show that the Carrizo APUs will be 28 nm products, presumably fabricated by GLOBALFOUNDRIES. Many were hoping that AMD would make the jump to 20 nm with this generation of products, but that does not seem to be the case. This is not surprising due to the limitations of that particular process when dealing with large designs that require a lot of current. AMD will likely be pushing for 16 nm FinFET for the generation of products after Carrizo.
The big Carrizo supposedly has a next generation GCN unit. My guess here is that it will use the same design as we saw with the R9 285. That particular product is a next generation unit that has improved efficiency. AMD did not release how many GCN cores will be present in Carizzo, but it will be very similar to what we see now with Kaveri. Carrizo-L will use the same GCN units as the previous generation Beema based products.
I believe AMD has spent a lot more time hand tuning Excavator instead of relying on a lot of automated place and route. This should allow them to retain much of the performance of the part, all the while cutting down on transistor count dramatically. Some rumors that I have seen point to each Excavator module being 40% smaller than Steamroller. I am not entirely sure they have achieved that type of improvement, but more hand layout does typically mean greater efficiency and less waste. The downside to hand layout is that it is extremely time and manpower intensive. Intel can afford this type of design while AMD has to rely more on automated place and route.
Carrizo will be the first HSA 1.0 compliant SOC. It is in fact an SOC as it integrates the southbridge functions that previously had been handled by external chips like the A88X that supports the current Kaveri desktop APUs. Carrizo and Carrizo-L will also share the same infrastructure. This means that motherboards that these APUs will be soldered onto are interchangeable. One motherboard from the partner OEMs will be able to address multiple markets that will see products range from 4 watts TDP up to 35 watts.
Finally, both APUs feature the security processor that allows them access to the ARM TrustZone technology. This is a very small ARM processor that handles the secure boot partition and handles the security requests. This puts AMD on par with Intel and their secure computing solution (vPro).
These products will be aimed only at the mobile market. So far AMD has not announced Carrizo for the desktop market, but when they do I would imagine that they will hit a max TDP of around 65 watts. AMD claims that Carrizo is one of the biggest jumps for them in terms of power efficiency. A lot of different pieces of technology have all come together with this product to make them more competitive with Intel and their process advantage. Time will tell if this is the case, but for now AMD is staying relevant and pushing their product releases so that they are more consistently ontime.

Tagged: Richland, Q3 results, lisa su, Kaveri, APU, amd, A10 7850K
While AMD made a small profit last quarter, the Q4 outlook from the company is not nearly as rosy. AMD estimates that Q4 revenues will be around 12% lower than Q3, making for a rare drop in what is typically a robust season for sales. Unlike Intel, AMD is seeing a very soft PC market for their products. Intel so far has been able to deliver parts that are as fast, if not faster than the latest APUs, but they also feature lower TDPs while at a comparable price. The one area that AMD has a significant advantage is in terms of 3D performance and better driver support.
To keep the chips selling during this very important quarter, AMD is cutting the prices on their entire lineup of FM2+ parts. This includes the entire Kaveri based lineup from the top end A10-7850K to the A6-7400K. AMD is also cutting the prices on the previous Richland based parts, which include the A10-6800K. Also of interest is that buyers of A10 APUs will be able to select one of three game titles (Murdered: Soul Suspect, Thief, or Sniper Elite 3) for free, or use the included code to purchase Corel’s Aftershot Pro 2 for only $5.
|Compute Cores||12 (4+8)||12 (4+8)||10 (4+6)||10 (4+6)||6 (2+4)|
|TDP (cTDP)||95 (65/45)||65 (45)||95 (65/45)||65 (45)||65 (45)|
The A10-7850K is a pretty good part overall, though of course it does suffer at the hands of Intel when it comes to pure CPU performance. It still is a pretty quick part that competes well with Intel’s 2 core/4 thread chips. 3D performance from the integrated graphics is class leading, and the potential for using that unit for HSA applications is another checkmark for AMD. We have yet to see widespread adoption of HSA, but we are seeing more and more software products coming out that support it. Having tested it out myself, the GPU portion of the APU can be enabled when using a standalone GPU from either AMD or NVIDIA. The Kaveri chips also support TrueAudio, which will show up in more titles throughout the next year.
One aspect of AMD’s latest FM2+ platform that cannot be ignored is the pretty robust selection of good and interesting motherboards that are offered at very low prices. Products such as the Gigabyte G1.Sniper.A88X and the MSI A88X-G45 Gaming motherboards are well rounded products that typically sell in the $90 to $110 range. Top end products like the Asus Crossblade Ranger are still quite affordable at around $160. Budget offerings are still pretty decent and they come in the $50 range.
One other product that has sparked interest is the Athlon X4 860K Black Edition. This product is clocked between 3.7 GHz and 4.0 GHz, features two Steamroller modules, and is priced at a very reasonable $90. The downside is that there is no GPU portion enabled, while the upside is that there is potentially more thermal headroom for the CPU portion to be clocked higher than previous A10-7850K parts. This will of course differ from individual chips, but the potential is there to have a pretty solid CPU for a very low price. Add in the low motherboard prices, and this has the making of a nice budget enthusiast system.
So why the cuts now? We can simply look at last week’s results for AMD’s previous quarter, as well as how the next quarter is stacking up. While AMD made a small profit last quarter, predictions for Q4 look grim. AMD is looking at around a 12% decrease in revenue, as stated above. AMD has a choice in that they can keep ASPs higher, but risk shipping less product in the very important 4th quarter; or they can sacrifice ASPs and potentially ship a lot more product. The end result of cutting the prices on their entire line of APUs will be of course lower ASPs, but a higher volume of parts being shipped and sold. In terms of cash flow, it is likely more important to see parts flowing rather than having higher inventories with a higher ASP. This also means that more APUs being sold will mean more motherboards from their partners moving through the channel.
Intel does have several huge advantages over AMD in that they have a very solid 22 nm process, a huge workforce that can hand tune their processors, and enough marketing money to make any company other than Apple squirm. AMD is at the mercy of the pure-play foundries in terms of process node tweaks and shrinks. AMD spent a long time at 32 nm PD-SOI before it was able to migrated to 28 nm HKMG. It looks to be 2015 before AMD sees anything below 28 nm for their desktop APUs, but it could be sooner for their smaller APUs and ARM based products on planar 20 nm HKMG processes. We don’t know a all of the specifics of the upcoming 16/14nm FinFET products from TSMC, Samsung, and GLOBALFOUNDRIES, so it will be hard to compare/contrast to Intel’s 2nd generation 14 nm TriGate line. All we know is that it will most assuredly be better than the current 28 nm HKMG that AMD is stuck at.

Today, AMD posted financial results for its second quarter of 2014. The company posted quarterly revenue of $1.44 billion, operating income of $63 million, and ultimately a net loss of $36 million (or $0.05 loss per share). The results are an improvement over both the previous quarter and a marked improvement over the same quarter last year.
The chart below compares the second quarter results to the previous quarter (Q1'14) and the same quarter last year (Q2'13). AMD saw increased revenue and operating income, but a higher net loss versus last quarter. Unfortunately, AMD is still saddled with a great deal of debt, which actually increased from 2.14 billion in Q1 2014 to $2.21 billion at the end of the second quarter.
|Q2 2014||Q1 2014||Q2 2014||Q2 2013|
|Revenue||$1.44 Billion||$1.40 Billion||$1.44 Billion||$1.16 Billion|
|Operating Income||$63 Million||$49 Million||$63 Million||($29 Million)|
|Net Profit/(Loss)||($36 Million)||($20 Million)||($36 Million)||($74 Million)|
The Computing Solutions division saw increased revenue of 1% over last quarter, but revenue fell 20% year over year due to fewer chips being sold.
On the bright side, the Graphics and Visual Solutions group saw quarterly revenue increase by 5% over last quarter and 141% YoY. The massive YoY increase is due, in part, to AMD's Semi-Custom Business unit and the SoCs that have come out of there (including the chips used in the latest gaming consoles).
Further, the company is currently sourcing 50% of its wafers from Global Foundries.
“Our transformation strategy is on track and we expect to deliver full year non-GAAP profitability and year-over-year revenue growth. We continue to strengthen our business model and shape AMD into a more agile company offering differentiated solutions for a diverse set of markets.”
-AMD CEO Rory Reed
AMD expects to see third quarter revenue increase by 2% (plus or minus 3%). Following next quarter, AMD will begin production of its Seattle ARM processors. Perhaps even more interesting will be 2016 when AMD is slated to introduce new x86 and GCN processors on a 20nm process.
The company is working towards being more efficient and profitable, and the end-of-year results will be interesting to see.

When I first read many of the initial AMD A10 7850K reviews, my primary question was how would the APU act if there was a different GPU installed on the system and did not utilize the CrossFire X functionality that AMD talked about. Typically when a user installs a standalone graphics card on the AMD FM2/FM2+ platform, they disable the graphics portion of the APU. They also have to uninstall the AMD Catalyst driver suite. So this then leaves the APU as a CPU only, and all of that graphics silicon is left silent and dark.
Who in their right mind would pair a high end graphics card with the A10-7850K? This guy!
Does this need to be the case? Absolutely not! The GCN based graphics unit on the latest Kaveri APUs is pretty powerful when used in GPGPU/OpenCL applications. The 4 cores/2 modules and 8 GCN cores can push out around 856 GFlops when fully utilized. We also must consider that the APU is the first fully compliant HSA (Heterogeneous System Architecture) chip, and it handles memory accesses much more efficiently than standalone GPUs. The shared memory space with the CPU gets rid of a lot of the workarounds typically needed for GPGPU type applications. It makes sense that users would want to leverage the performance potential of a fully functioning APU while upgrading their overall graphics performance with a higher end standalone GPU.
To get this to work is very simple. Assuming that the user has been using the APU as their primary graphics controller, they should update to the latest Catalyst drivers. If the user is going to use an AMD card, then it would behoove them to totally uninstall the Catalyst driver and re-install only after the new card is installed. After this is completed restart the machine, go into the UEFI, and change the primary video boot device to PEG (PCI-Express Graphics) from the integrated unit. Save the setting and shut down the machine. Insert the new video card and attach the monitor cable(s) to it. Boot the machine and either re-install the Catalyst suite if an AMD card is used, or install the latest NVIDIA drivers if that is the graphics choice.
Windows 7 and Windows 8 allow users to install multiple graphics drivers from different vendors. In my case I utilized a last generation GTX 580 (the MSI N580GTX Lightning) along with the AMD A10 7850K. These products coexist happily together on the MSI A88X-G45 Gaming motherboard. The monitor is attached to the NVIDIA card and all games are routed through that since it is the primary graphics adapter. Performance seems unaffected with both drivers active.
I find it interesting that the GPU portion of the APU is named "Spectre". Who owns those 3dfx trademarks anymore?
When I load up Luxmark I see three entries: the APU (CPU and GPU portions), the GPU portion of the APU, and then the GTX 580. Luxmark defaults to the GPUs. We see these GPUs listed as “Spectre”, which is the GCN portion of the APU, and the NVIDIA GTX 580. Spectre supports OpenCL 1.2 while the GTX 580 is an OpenCL 1.1 compliant part.
With both GPUs active I can successfully run the Luxmark “Sala” test. The two units perform better together than when they are run separately. Adding in the CPU does increase the score, but not by very much (my guess here is that the APU is going to be very memory bandwidth bound in such a situation). Below we can see the results of the different units separate and together.
These results make me hopeful about the potential of AMD’s latest APU. It can run side by side with a standalone card, and applications can leverage the performance of this unit. Now all we need is more HSA aware software. More time and more testing is needed for setups such as this, and we need to see if HSA enabled software really does see a boost from using the GPU portion of the APU as compared to a pure CPU piece of software or code that will run on the standalone GPU.
Personally I find the idea of a heterogeneous solution such as this appealing. The standalone graphics card handles the actual graphics portions, the CPU handles that code, and the HSA software can then fully utilize the graphics portion of the APU in a very efficient manner. Unfortunately, we do not have hard numbers on the handful of HSA aware applications out there, especially when used in conjunction with standalone graphics. We know in theory that this can work (and should work), but until developers get out there and really optimize their code for such a solution, we simply do not know if having an APU will really net the user big gains as compared to something like the i7 4770 or 4790 running pure x86 code.
In the meantime, at least we know that these products work together without issue. The mixed mode OpenCL results make a nice case for improving overall performance in such a system. I would imagine with more time and more effort from developers, we could see some really interesting implementations that will fully utilize a system such as this one. Until then, happy experimenting!

Tagged: x86, restructure, gpu, arm, APU, amd
According to VR-Zone, AMD has reworked their business, last Thursday, sorting each of their projects into two divisions and moving some executives around. The company is now segmented into the "Enterprise, Embedded, and Semi-Custom Business Group", and the "Computing and Graphics Business Group". The company used to be divided between "Computing Solutions", which handled CPUs, APUs, chipsets, and so forth, "Graphics and Visual Solutions", which is best known for GPUs but also contains console royalties, and "All Other", which was... everything else.
Lisa Su, former general manger of global business, has moved up to Chief Operating Officer (COO), along with other changes.
This restructure makes sense for a couple of reasons. First, it pairs some unprofitable ventures with other, highly profitable ones. AMD's graphics division has been steadily adding profitability to the company while its CPU division has been mostly losing money. Secondly, "All Other" is about a nebulous as a name can get. Instead of having three unbalanced divisions, one of which makes no sense to someone glancing at AMD's quarterly earnings reports, they should now have two, roughly equal segments.
At the very least, it should look better to an uninformed investor. Someone who does not know the company might look at the sheet and assume that, if AMD divested from everything except graphics, that the company would be profitable. If, you know, they did not know that console contracts came into their graphics division because their compute division had x86 APUs, and so forth. This setup is now more aligned to customers, not products.

Tagged: ulv, mobile apu, laptop, Kaveri, APU, amd
According to leaked information, AMD will allegedly be releasing mobile versions of its Kaveri APU later this year. There are reportedly seven new processors aimed at laptops and tablet that follow the same basic design as their desktop counterparts: steamroller CPU cores paired with a GCN-based graphics portion and an integrated memory controller.
According to information obtained by WCCF Tech, AMD will release four ULV and three standard voltage parts. All but one APU will have four Steamroller CPU cores paired with an Radeon R4, R5, R6, or R7 graphics processor with up to 512 GCN cores. The mobile APUs allegedly range in TDP from 17W to 35W and support various AMD technologies including TrueAudio, Mantle, and Eyefinity.
An AMD slide showing a die shot of the desktop "Kaveri" Accelerated Processing Unit (APU).
Of the seven rumored APUs, two of them are OEM-only parts that feature the “FX” moniker. The FX-7500 is the fastest ULV (ultra-low voltage) APU while the FX-7600P is AMD’s flagship mobile processor.
The FX-7600P is the chip that should most interest mobile gamers and enthusiasts looking for a powerful AMD-powered laptop or tablet. This processor allegedly features four CPU cores clocked at 2.7GHz base (that turbo to a maximum of 3.6GHz), a GPU with 512 GCN cores clocked at a base of 600MHz and a boost clock of 666MHz. The chip further uses 4MB of L2 cache and is a 35W TDP part. This should be a decent processor for laptops, offering acceptable general performance and some nice mobile gaming with the beefy integrated GPU!
The leaked AMD mobile Kaveri APU lineup via WCCF Tech.
Of course, for productivity machines where portability and battery life are bigger concerns, AMD will reportedly be offering up the dual core A6-7000. This 17W ULV processor combines two cores clocked at 2.2GHz (3.0GHz boost), a GPU based on the Radeon R4 with 192 GCN cores (494MHz base and 533MHz boost), and 2MB of L2 cache. Compared to the FX-7600P (and especially the desktop parts), the A6-7000 sips power. We will have to wait for reviews to see how it performs, but it will be facing stiff competition from Intel’s Core i3 Haswell CPUs and even the Bay Trail SoCs which come in at a lower TDP and offer higher thread counts. The GPU capabilities and GPGPU / HSA software advancements (such as LibreOffice adding GPGPU support) will make or break the A6-7000, in my opinion.
In all, the leaked mobile chips appear to be a decent upgrade over the previous generation. The new mobile APUs will bring incremental performance and power saving benefits to bear against competition from Intel. I’m looking forward to more official information and seeing what the OEMs are able to do with the new chips.
Ultra-Speed RAM, APU-Style
In our review of the Kingston HyperX Predator 2666MHz kit, we discovered what those knowledgeable about Intel memory scaling already knew: for most applications, and specifically games, there is no significant advantage to increases in memory speed past the current 1600MHz DDR3 standard. But this was only half of the story. What about memory scaling with an AMD processor, and specifically an APU? To find out, we put AMD’s top APU, the A10-7850K, to the test!
Ready for some APU memory testing!
AMD has created a compelling option with their APU lineup, and the inclusion of powerful integrated graphics allows for interesting build options with lower power and space requirements, and even make building tiny mini-ITX systems for gaming realistic. It’s this graphical prowess compared to any other onboard solution that creates an interesting value proposition for any gamer looking at a new low-cost build. The newest Kaveri APU’s are getting a lot of attention and they beg the question, is a discrete graphics card really needed for gaming at reasonable settings?

Tagged: Kaveri, APU, amd, A10-7850K
It is about time we took a look at AMD's new flagship processor, the A10-7850K Kaveri chip running at 3.7GHz or 4GHz at full boost with 4 Steamroller CPU cores and 8 Hawaii GPU cores. While we are still shy on HSA benchmarks at the moment, HiTech Legion did have a chance to do some Mantle testing with the APU alone and paired with a discrete GPU which showed off some of the benefits on Mantle. They also reached a decent overclock, a hair shy of 4.5GHz on air which is not too shabby for a processor that costs under $200. Check out the full review here.
"AMD has launched their fourth generation of APU, codenamed “Kaveri”. Kaveri boasts increased processor power coupled with advanced Radeon graphics but there are other technologies, such as HSA, that balance memory loads via “compute” to both the CPU and GPU."

Low Power and Low Price
Back at CES earlier this year, we came across a couple of interesting motherboards that were neither AM3+ nor FM2+. These small, sparse, and inexpensive boards were actually based on the unannounced AM1 platform. This socket is actually the FS1b socket that is typically reserved for mobile applications which require the use of swappable APUs. The goal here is to provide a low cost, upgradeable platform for emerging markets where price is absolutely key.
AMD has not exactly been living on easy street for the past several years. Their CPU technologies have not been entirely competitive with Intel. This is their bread and butter. Helping to prop the company up though is a very robust and competitive graphics unit. The standalone and integrated graphics technology they offer are not only competitive, but also class leading in some cases. The integration of AMD’s GCN architecture into APUs has been their crowning achievement as of late.
This is not to say that AMD is totally deficient in their CPU designs. Their low power/low cost designs that started with the Bobcat architecture all those years back have always been very competitive in terms of performance, price, and power consumption. The latest iteration is the Kabini APU based on the Jaguar core architecture paired with GCN graphics. Kabini will be the part going into the FS1b socket that powers the AM1 platform.
Kabini is a four core processor (Jaguar) with a 128 unit GCN graphics part (8 GCN cores). These APUs will be rated at 25 watts up and down the stack. Even if they come with half the cores, it will still be a 25 watt part. AMD says that 25 watts is the sweet spot in terms of performance, cooling, and power consumption. Go lower than that and too much performance is sacrificed, and any higher it would make more sense to go with a Trinity/Richland/Kaveri solution. That 25 watt figure also encompasses the primary I/O functionality that typically resides on a standalone motherboard chipset. Kabini features 2 SATA 6G ports, 2 USB 3.0 ports, and 8 USB 2.0 ports. It also features multiple PCI-E lanes as well as a 4x PCI-E connection for external graphics. The chip also supports DisplayPort, HDMI, and VGA outputs. This is a true SOC from AMD that does a whole lot of work for not a whole lot of power.
