AMD Kaveri analysis header 800x450

AMD’s Kaveri launch has been going smoothly for the most part. Socket FM2+ motherboards are now available at decent stock levels worldwide and the chips themselves are also not too expensive in the markets that AMD feels they can grow in (that excludes South Africa, where they are still exorbitantly priced). However, Kaveri’s biggest market where it could have made the most impact, which is in mobile devices like laptops and ultrabooks, is still not seeing the chips that AMD needs to put out to make any significant inroads. This seems to be one of the company’s primary concerns because a table detailing the leaked chips has been unearthed by WCCF Tech, providing hints at clock speeds, product names and even dual graphics pairings for the upcoming mobile chip family.

Admittedly, much of what you see here today could be inaccurate and these leaks almost always are in some way. For what it’s worth, things seem to tally up for now except the GPU frequencies. All the APUs are still apparently using DDR3 memory, with 1600MHz speeds being the minimum recommended speed. It appears that AMD has learnt its lesson with memory slot assignments and dual graphics pairings because it’ll apparently be required for OEMs to include two memory slots for dual-channel setups.

One nice thing about the upcoming Kaveri launch is that it includes all the bells and whistles found on the desktop chips. This includes the TrueAudio hardware, support for Mantle and Eyefinity and dual graphics setups (more on that in a minute).

AMD Mobile Kaveri leak full lineup

The lineup is to be split up into three categories – there’s the A6-7600 which is a dual-core with Radeon R4 graphics comprising of 192 shader cores. Effectively, using AMD’s new naming system for HSA-compliant hardware, the A6-7600 is comprised of four Compute Units (CUs). CUs are determined through how many CPU modules are used (two cores per module, one module is one CU) and how many shader units there are (one shader unit = 64 shader cores = one CU).

Then there’s the A8 and A10 series, both of which are quad-cores. The A8-7100 and A8-7200P are both low-voltage chips with big differences in CPU and GPU clock speeds as well as hardware assignments and Thermal Design Power (TDP) limits. With four cores and 256 shader units each, they comprise of 6 HSA-compliant CUs. The A8-7200P will be the faster of the two, although the A8-7100 will find its way into systems like netbooks and small-form-factor (SFF) desktops that mount to the back of your monitor.

The A10 series bumps that up to eight CUs with two models, a 19W and 35W part. Clock speeds on the CPU and GPU differ quite a bit but core counts remain the same. The A10-7300 and A10-7400P will find their way into mid-range 15.6″ notebooks which will tend to the bulky side to dissipate the heat that a APU with a 35W TDP could generate.

The FX chips are the ones that you’ll see replacing APUs found in notebooks like MSI’s GX60 and GX70 series. The previous chips were based on AMD’s Bulldozer architecture, re-engineered to fit into the APU space and became known by the Trinity codename. Most OEMs missed the Piledriver bandwagon, which would have introduced power savings and performance boosts thanks to AMD’s Resonant Clock Mesh (RCM) technology which fixed most of the issues that still dogged their CPU and GPU boost algorithms. Steamroller, which is much faster and less of a bottleneck to larger GPUs, would be a better fit into the high-performance mobile market.

AMD-Kaveri-Mobile-Graphics list

WCCF Tech’s other tidbit was a screenshot of how AMD is planning to roll out dual graphics configurations and some of the pairings here are very odd, mainly because these aren’t options for desktop users just yet. The only card that cannot run with anything else in dual graphics is the A6-7600 APU. However, for the rest of the lineup there are options for every other quad-core APU including and up to the mobile Radeon R7 M270DX.

These secondary GPUs in the list may be using either DDR3 or GDDR5 memory hence the appearance of a Radeon R7 M275DX and a R7 M270DX and so on. There are no indications of what the DDR3 frequencly limit for the APU is so we’re going to have to take 1866MHz as the baseline here. Any of the solutions listed here, even the A8-7100 with the Radeon R6 M255DX, should provide acceptable gaming performance at 720p with medium to low settings depending on the game in question. Likewise, any combination of 35W parts should be more than enough for some solid 1080p gaming with medium to high settings.

AMD has not announced any launch dates for the Kaveri family but if they want to get in on the action while Nvidia’s Maxwell is still not too far ahead, they need to do it soon.
