Linux support for AMD's GPUs has not been progressing at the pace many users would like, though it is improving over time but that is not the same with their APUs. Phoronix just tested the A10-7800 and A6-7400K on Ubuntu 14.04 with kernel 3.13 and the latest Catalyst 14.6 Beta. This preview just covers the raw performance, you can expect to see more published in the near future that will cover new features such as the configurable TDP which exists on these chips. The tests show that the new 7800 can keep pace with the previous 7850K and while the A6-7400K is certainly slower it will be able to handle a Linux machine with relatively light duties. You can see the numbers here.
"At the end of July AMD launched new Kaveri APU models: the A10-7800, A8-7600, and A6-7400K. AMD graciously sent over review samples on their A10-7800 and A6-7400K Kaveri APUs, which we've been benchmarking and have some of the initial Linux performance results to share today."

Filling the Product Gaps
In the first several years of my PCPer employment, I typically handled most of the AMD CPU refreshes. These were rather standard affairs that involved small jumps in clockspeed and performance. These happened every 6 to 8 months, with the bigger architectural shifts happening some years apart. We are finally seeing a new refresh of the AMD APU parts after the initial release of Kaveri to the world at the beginning of this year. This update is different. Unlike previous years, there are no faster parts than the already available A10-7850K.
This refresh deals with fleshing out the rest of the Kaveri lineup with products that address different TDPs, markets, and prices. The A10-7850K is still the king when it comes to performance on the FM2+ socket (as long as users do not pay attention to the faster CPU performance of the A10-6800K). The initial launch in January also featured another part that never became available until now; the A8-7600 was supposed to be available some months ago, but is only making it to market now. The 7600 part was unique in that it had a configurable TDP that went from 65 watts down to 45 watts. The 7850K on the other hand was configurable from 95 watts down to 65 watts.
So what are we seeing today? AMD is releasing three parts to address the lower power markets that AMD hopes to expand their reach into. The A8-7600 was again detailed back in January, but never released until recently. The other two parts are brand new. The A10-7800 is a 65 watt TDP part with a cTDP that goes down to 45 watts. The other new chip is the A6-7600K which is unlocked, has a configurable TDP, and looks to compete directly with Intel’s recently released 20 year Anniversary Pentium G3258.
Redefining Price/Performance with AMD Motherboards
Motherboards are fascinating to me. They always have been. I remember voraciously reading motherboard reviews in the mid-90s. I simply could not get enough of them. Some new chipset from SiS, VIA, or ALi? I scoured the internet for information on them and what new features they would bring to the table. Back then motherboards did not have the retail presence they do now. The manufacturers were starting to learn to differentiate their products and cater to the enthusiasts who would not only buy and support these products, but also recommend them to friends/family/the world.
Today motherboards are really the foundation for any PC build. Choosing a motherboard is no longer just picking up some whitebox board that has a 440 BX chipset. Now users are much more active in debating what kind of features they need, what kind of feedback has this manufacturer received from consumers, what kind of ratings the board has on Amazon or Newegg. Features like build quality or overclocking performance sway users from company to company and product to product.
In the past 15 years or so we have seen some pretty rigid guidelines for pricing of motherboards. The super cheap “PC Chips” style motherboards existed below the $90 range. The decent, but unexciting motherboards with the bare minimum of features would go from $90 to $150. The $150 and beyond products were typically considered enthusiast class motherboards with expanded features, better build quality, and more robust power delivery options. Thankfully for consumers, this model is being shaken up by the latest generation of products from AMD.
MSI insures that everything is nicely packed and protected in their black and red box.
I mentioned in the previous Gigabyte G1.Sniper.A88X review that AMD and its partners do not have the luxury of offering a $150 and above FM2+ motherboard due to the nature (and pricing) of the latest FM2+ APUs. I am fairly sure the amount of people willing to spend $200 on a motherboard to house a $179 APU that seemingly overclocks as well on a cheap board as it does a more expensive one (meaning, not very well at all) is pretty low. If there is one bright side to the latest Kaveri APUs, it is that the graphics portion is extremely robust in both graphics and OpenCL applications. The hope for AMD and users alike is that HSA will in fact take off and provide a significant performance boost in a wide variety of applications that typically require quite a bit of horsepower.

FM2+ Has a High End?
AMD faces a bit of a quandary when it comes to their products. Their APUs are great at graphics, but not so great at general CPU performance. Their products are all under $200 for the CPU/APU but these APUs are not popular with the enthusiast and gaming crowd. Yes, they can make excellent budget gaming systems for those who do not demand ultra-high resolutions and quality settings, but it is still a tough sell for a lot of the mainstream market; the primary way AMD pushes these products is price.
Perhaps the irony here is that AMD is extremely competitive with Intel when it comes to chipset features. The latest A88X Fusion Control Hub is exceptionally well rounded with four native USB 3.0 ports, ten USB 2.0 ports, and eight SATA-6G ports. Performance of this chipset is not all that far off from what Intel offers with the Z87 chipset (USB and SATA-6G are slower, but not dramatically so). The chip also offers RAID 0, 1, 5, and 10 support as well as a 10/100/1000 Ethernet MAC (but a physical layer chip is still required).
Now we get back to price. AMD is not charging a whole lot for these FCH units, even the top end A88X. I do not have the exact number, but it is cheap as compared to the competing Intel option. Intel’s chipset business has made money for the company for years, but AMD does not have that luxury. AMD needs to bundle effectively to be competitive, so it is highly doubtful that the chipset division makes a net profit at the end of the day. Their job is to help push AMD’s CPU and APU offerings as much as possible.
These low cost FCH chips allow motherboard manufacturers to place a lot of customization on their board, but they are still limited in what they can do. A $200+ motherboard simply will not fly with consumers for the level of overall performance that even the latest AMD A10 7850K APU provides in CPU bound workloads. Unfortunately, HSA has not yet taken off to leverage the full potential of the Kaveri APU. We have had big developments, just not big enough that the majority of daily users out there will require an AMD APU. Until that happens, AMD will not be viewed favorably when it comes to its APU offerings in gaming or high performance systems.
The quandary obviously is how AMD and its motherboard partners can create inexpensive motherboards that are feature packed, yet will not break the bank or become burdensome towards APU sales? The FX series of processors from AMD do have a bit more leeway as the performance of the high end FX-8350 is not considered bad, and it is a decent overclocker. That platform can sustain higher motherboard costs due to this performance. The APU side, not so much. The answer to this quandary is tradeoffs.
Kaveri Goes Mobile
The processor market is in an interesting place today. At the high end of the market Intel continues to stand pretty much unchallenged, ranging from the Ivy Bridge-E at $1000 to the $300 Haswell parts available for DIY users. The same could really be said for the mobile market - if you want a high performance part the default choice continues to rest with Intel. But AMD has some interesting options that Intel can't match when you start to enter the world of the mainstream notebook. The APU was slow to develop but it has placed AMD in a unique position, separated from the Intel processors with a more or less reversed compute focus. While Intel dominates in the performance on the x86 side of things, the GPU in AMD's latest APUs continue to lead in gaming and compute performance.
The biggest problem for AMD is that the computing software ecosystem still has not caught up with the performance that a GPU can provide. With the exception of games, the GPU in a notebook or desktop remains under utilized. Certain software vendors are making strides - see the changes in video transcoding and image manipulation - but there is still some ground AMD needs to accelerate down.
Today we are looking at the mobile version of Kaveri, AMD's latest entry into the world of APUs. This processor combines the latest AMD processor architecture with a GCN-based graphics design for a pretty advanced part. When the desktop version of this processor was released, we wrote quite a bit about the architecture and the technological advancements made into, including becoming the first processor that is fully HSA compliant. I won't be diving into the architecture details here since we covered them so completely back in January just after CES.
The mobile version of Kaveri is basically identical in architecture with some changes for better power efficiency. The flagship part will ship with 12 Compute Cores (4 Steamroller x86 cores and 8 GCN cores) and will support all the same features of GCN graphics designs including the new Mantle API.
Early in the spring we heard rumors that the AMD FX brand was going to make a comeback! Immediately enthusiasts were thinking up ways AMD could compete against the desktop Core i7 parts from Intel; could it be with 12 cores? DDR4 integration?? As it turns out...not so much.

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!

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.

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."

Tagged: msi, A58, Kaveri, FM2+, micro ATX, atx
MSI has launched three new low cost FM2+ motherboards based around AMD's budget A58 chipset. The new boards include an ATX form factor MSI A58-G41 PC Mate and two micro ATX boards: the A58M-E35 and the A58M-E33. The boards are compatible with AMD's Richland, Trinity, and Kaveri APUs and support PCI-E 3.0. The cost savings come from using the A58 chipset which drops support for SATA III 6Gpbs and USB 3.0. The boards further have smaller heatsinks and fewer overclocking features. Despite the restrictions, the new MSI A58 FM2+ motherboards still incorporate MSI's OC Genie 4, Click BIOS 4, and Command Center technologies along with the company's Military Class 4 hardware components.
The MSI A58-G41 PC Mate is an ATX form factor board with an FM2+ CPU socket, two DDR3 DIMM slots, six SATA II 3Gbps ports, two PCI-E 3.0 x16 slots, two PCI-E 3.0 x1 slots, and three legacy PCI expansion slots. Rear IO on this board includes two PS/2 ports, six USB 2.0 ports, a single Gigabit LAN port, three analog audio jacks, and three video outputs (HDMI, VGA, and DVI).
The Micro ATX A58M-E35 also has an FM2+ socket, two DDR3 DIMM slots, and six SATA II ports, but the expansion slot layout is scaled down. There is a single PCI-E 3.0 x16 slot, one PCI-E 3.0 x1 slot, and one PCI slot. Rear IO on this board is identical to the A58-G41 board above (six USB 2.0, two PS/2, one GbE port, three audio, and three video outputs).
Finally, MSI's lowest-end A58M-E33 is a Micro ATX board similar in layout to the A58-E35, but with fewer port options. The expansion slot and memory slot configuration stays the same as the E35, but there are two fewer SATA II ports (four total) and two fewer USB 2.0 ports on the rear IO panel. Speaking of I/O, the board is similar to the E35 except that it lacks a DVI video output and two USB 2.0 ports.
MSI has not yet released exact pricing, but expect these boards to be well under $100, and the two micro ATX variants to be closer to the $50 mark based on prices of the higher-end A78 and A88 chipset-based motherboards. All three will be available for purchase later this year.

You don't often see performance scaling as clean as what Phoronix saw when testing the effect of memory speed on AMD's A10-7850K. Pick any result and you can clearly see a smooth increase in performance from DDR3-800 to DDR3-2400. The only time that increase seems to decline slightly is between DDR3-2133 and 2400MHz, with some tests showing little to no increase between those two speeds. Some tests do still show an improvement, for certain workloads on Linux the extra money is worth it but in other cases you can save a few dollars and limit yourself to the slightly cheaper DDR3-2133. Check out the full review here.
"Earlier in the week I published benchmarks showing AMD Kaveri's DDR3-800MHz through DDR3-2133MHz system memory performance. Those results showed this latest-generation AMD APU craving -- and being able to take advantage of -- high memory frequencies. Many were curious how DDR3-2400MHz would fair with Kaveri so here's some benchmarks as we test out Kingston's HyperX Beast 8GB DDR3-2400MHz memory kit."
