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.

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.

Taking the A10-7850K out for a spin and leaving marks on the bench

Subject: Processors | March 27, 2014 - 03:44 PM |
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."

MSI Intros Trio Of Low-Cost FM2+ Motherboards Using A58 Chipset

Subject: Motherboards | February 28, 2014 - 01:23 AM |
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).

MSI A58M-E33.png

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.

Kaveri loves fast memory

Tagged: ddr3, Kaveri, A10 7850K, amd, linux

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."

Hybrid CrossFire that actually works

The road to redemption for AMD and its driver team has been a tough one.  Since we first started to reveal the significant issues with AMD's CrossFire technology back in January of 2013 the Catalyst driver team has been hard at work on a fix, though I will freely admit it took longer to convince them that the issue was real than I would have liked.  We saw the first steps of the fix released in August of 2013 with the release of the Catalyst 13.8 beta driver.  It supported DX11 and DX10 games and resolutions of 2560x1600 and under (no Eyefinity support) but was obviously still less than perfect.  

In October with the release of AMD's latest Hawaii GPU the company took another step by reorganizing the internal architecture of CrossFire on the chip level with XDMA.  The result was frame pacing that worked on the R9 290X and R9 290 in all resolutions, including Eyefinity, though still left out older DX9 titles.  

One thing that had not been addressed, at least not until today, was the issues that surrounded AMD's Hybrid CrossFire technology, now known as Dual Graphics.  This is the ability for an AMD APU with integrated Radeon graphics to pair with a low cost discrete GPU to improve graphics performance and gaming experiences.  Recently over at Tom's Hardware they discovered that Dual Graphics suffered from the exact same scaling issues as standard CrossFire; frame rates in FRAPS looked good but the actually perceived frame rate was much lower.

drivers01.jpg

A little while ago a new driver made its way into my hands under the name of Catalyst 13.35 Beta X, a driver that promised to enable Dual Graphics frame pacing with Kaveri and R7 graphics cards.  As you'll see in the coming pages, the fix definitely is working.  And, as I learned after doing some more probing, the 13.35 driver is actually a much more important release than it at first seemed.  Not only is Kaveri-based Dual Graphics frame pacing enabled, but Richland and Trinity are included as well.  And even better, this driver will apparently fix resolutions higher than 2560x1600 in desktop graphics as well - something you can be sure we are checking on this week!

drivers02.jpg

Just as we saw with the first implementation of Frame Pacing in the Catalyst Control Center, with the 13.35 Beta we are using today you'll find a new set of options in the Gaming section to enable or disable Frame Pacing.  The default setting is On; which makes me smile inside every time I see it.

drivers03.jpg

The hardware we are using is the same basic setup we used in my initial review of the AMD Kaveri A8-7600 APU review.  That includes the A8-7600 APU, an Asrock A88X mini-ITX motherboard, 16GB of DDR3 2133 MHz memory and a Samsung 840 Pro SSD.  Of course for our testing this time we needed a discrete card to enable Dual Graphics and we chose the MSI R7 250 OC Edition with 2GB of DDR3 memory.  This card will run you an additional $89 or so on Amazon.com.  You could use either the DDR3 or GDDR5 versions of the R7 250 as well as the R7 240, but in our talks with AMD they seemed to think the R7 250 DDR3 was the sweet spot for the CrossFire implementation.

IMG_9457.JPG

Both the R7 250 and the A8-7600 actually share the same number of SIMD units at 384, otherwise known as 384 shader processors or 6 Compute Units based on the new nomenclature that AMD is creating.  However, the MSI card is clocked at 1100 MHz while the GPU portions of the A8-7600 APU are running at only 720 MHz. 

So the question is, has AMD truly fixed the issues with frame pacing with Dual Graphics configurations, once again making the budget gamer feature something worth recommending?  Let's find out!

Tagged: overclocking, Kaveri, amd

HCW does quite a few overclocking reviews for both Intel and AMD processors. This time, Carl Nelson got a hold of the high-end AMD A10-7850K and gave it a pretty healthy boost in frequencies. By the time he was done with it, the CPU was operating a whole gigahertz above stock simultaneous with a 300 MHz boost to its integrated graphics.

3DMark 2013 Fire Strike scores gained 27%.

One again, they break down tests along a suite of different games of varying engines and add some OpenCL tests to round things out. In real-world applications, the increase was not quite as dramatic as the one seen in 3DMark but still significant. This overclock allowed certain games to jump from 720p to playable at 1080p. Apparently this silicon is a decent little overclocker.

AMD Kaveri Platform Highlights
The latest AMD A10-7850K and A10-7700K APUs integrate an enhanced CPU core based on the ‘Steamroller’ architecture with a new and updated Radeon Graphics core. Supporting native 8 GT/s PCI Express gen 3.0 and DX11.1 graphics, these new AMD A-Series APUs also offer native support for 4K resolution displays on HDMI and DisplayPort.

Heterogeneous System Architecture (HSA) Maintained by the HSA Foundation, HSA is a system architecture that allows accelerators such as the graphics processor (GPU) to operate at the same processing level as the system's CPU, providing up to 50 per cent more GPU performance and up to 20 per cent more x86 instructions executed per cycle compared to previous implementations. The new AMD A10 series APUs are the first desktop PC processors to implement the performance advantages of HSA.

AMD announces Garlic and Onion flavours on their first HSA chips

Not only are the first Kaveri reviews arriving today, the A10-7850K is up for sale on both NewEgg and Amazon and the A10-7700K is available on NewEgg.  This new part, at 45W competes favourably with the previous 100W Trinity APU in most tests and when Ryan boosted it to 65W it gained a little more.  The Steamroller cores have been updated but not in a way that has a huge effect on CPU performance, on the other hand the 384 SIMD units composing the GPU portion of this chip are quite impressive, 1080p gaming of current generation titles is possible on this chip and we haven't seen it's big brother with 512 SIMD units yet.  In the Tech Report's review you can see that BF4 is playable on this chip and this is not the Mantle version optimized for AMD's new architecture.  It is also a pity that Thief was unavailable to see just what TrueAudio is capable of.  Unfortunately this chip will not find its home in gamers dream machines, that is simply not where AMD is targeting its CPUs.  However, for SFF systems that need to be energy efficient and where a discrete GPU is to big to fit Kaveri will usher in a new level of performance.

"AMD's next-generation APU packs in a ton of innovation, including updated "Steamroller" CPU cores, GCN graphics, and advanced HSA features. But is it enough to restore AMD's competitiveness in desktop processors?"
