Lower Power, Same Performance
AMD is in a strange position in that there is a lot of excitement about their upcoming Zen architecture, but we are still many months away from that introduction. AMD obviously needs to keep the dollars flowing in, and part of that means that we get refreshes now and then of current products. The “Kaveri” products that have been powering the latest APUs from AMD have received one of those refreshes. AMD has done some redesigning of the chip and tweaked the process technology used to manufacture them. The resulting product is the “Godavari” refresh that offers slightly higher clockspeeds as well as better overall power efficiency as compared to the previous “Kaveri” products.
One of the first refreshes was the A8-7670K that hit the ground in November of 2015. This is a slightly cut down part that features 6 GPU compute units vs. the 8 that a fully enabled Godavari chip has. This continues to be a FM2+ based chip with a 95 watt TDP. The clockspeed of this part goes from 3.6 GHz to 3.9 GHz. The GPU portion runs at the same 757 MHz that the original A10-7850K ran at. It is interesting to note that it is still a 95 watt TDP part with essentially the same clockspeeds as the 7850K, but with two fewer GPU compute units.
The other product being covered here is a bit more interesting. The A10-7860K looks to be a larger improvement from the previous 7850K in terms of power and performance. It shares the same CPU clockspeed range as the 7850K (3.6 GHz to 3.9 GHz), but improves upon the GPU clockspeed by hitting around 800 MHz. At first this seems underwhelming until we realize that AMD has lowered the TDP from 95 watts down to 65 watts. Less power consumed and less heat produced for the same performance from the CPU side and improved performance from the GPU seems like a nice advance.
AMD continues to utilize GLOBALFOUNDRIES 28 nm Bulk/HKMG process for their latest APUs and will continue to do so until Zen is released late this year. This is not the same 28 nm process that we were introduced to over four years ago. Over that time improvements have been made to improve yields and bins, as well as optimize power and clockspeed. GF also can adjust the process on a per batch basis to improve certain aspects of a design (higher speed, more leakage, lower power, etc.). They cannot produce miracles though. Do not expect 22 nm FinFET performance or density with these latest AMD products. Those kinds of improvements will show up with Samsung/GF’s 14nm LPP and TSMC’s 16nm FF+ lines. While AMD will be introducing GPUs on 14nm LPP this summer, the Zen launch in late 2016 will be the first AMD CPU to utilize that advanced process.

Tagged: Wraith, Godavari, GLOBALFOUNDRIES, FM2+, amd, X4 880K
Remember that FM2+ refresh which Josh informed you about back in March? The APUs have started arriving on test benches and can be benchmarked independently to see what this ~$100 processor and the Wraith cooler are capable of. Neoseeker compares the new 880K against the older FX-4350 in a long series of benchmarks which show the 880K to be the better part in most cases. There are some interesting exceptions to this, in which the FX-4350's slightly higher frequency allows it to pull ahead by a small margin so there are cases where the less expensive chip would make sense. Read the full review to see which chip makes more sense for you.
"Today we take a look at the AMD Athlon X4 880K, a quad-core FM2+ processor with 4.0/4.2GHz base/Turbo clocks and unlocked multiplier priced at under $100 USD. It's designed for enthusiasts on a budget looking for the fastest multi-core Athlon processor yet without any integrated GPU to add to the cost. It even shares the 95W TDP of AMD's higher-end APUs for optimized power consumption that further leads to more overclocking headroom."
Here are some more Processor articles from around the web:

Clockspeed Jump and More!
On March 1st AMD announced the availability of two new processors as well as more information on the A10 7860 APU.
The two new units are the A10-7890K and the Athlon X4 880K. These are both Kaveri based parts, but of course the Athlon has the GPU portion disabled. Product refreshes for the past several years have followed a far different schedule than the days of yore. Remember back in time when the Phenom II series and the competing Core 2 series would have clockspeed updates that were expected yearly, if not every half year with a slightly faster top end performer to garner top dollar from consumers?
Things have changed, for better or worse. We have so far seen two clockspeed bumps for the Kaveri /Godavari based APU. Kaveri was first introduced over two years ago with the A10-7850K and the lower end derivatives. The 7850K has a clockspeed that ranges from 3.7 GHz to the max 4 GHz with boost. The GPU portion is clocked at 720 MHz. This is a 95 watt TDP part that is one of the introductory units from GLOBALFOUNDRIES 28 nm HKMG process.
Today the new top end A10-7890K is clocked at 4.1 GHz to 4.3 GHz max. The GPU receives a significant boost in performance with a clockspeed of 866 MHz. The combination of CPU and GPU clockspeed increases push the total performance of the part exceeding 1 TFLOPs. It features the same dual module/quad core Godavari design as well as the 8 GCN Units. The interesting part here is that the APU does not exceed the 95 watt TDP that it shares with the older and slower 7850K. It is also a boost in performance from last year’s refresh of the A10-7870K which is clocked 200 MHz slower on the CPU portion but retains the 866 MHz speed of the GPU. This APU is fully unlocked so a user can easily overclock both the CPU and GPU cores.
The Athlon X4 880K is still based on the Godavari family rather than the Carizzo update that the X4 845 uses. This part is clocked from 4.0 to 4.2 GHz. It again retains the 95 watt TDP rating of the previous Athlon X4 CPUs. Previously the X4 860K was the highest clocked unit at 3.7 GHz to 4.0, but the 880K raises that to 4 to 4.2 GHz. A 300 MHz gain in base clock is pretty significant as well as stretching that ceiling to 4.2 GHz. The Godavari modules retain their full amount of L2 cache so the 880K has 4 MB available to it. These parts are very popular with budget enthusiasts and gaming builds as they are extremely inexpensive and perform at an acceptable level with free overclocking thrown in.

Using the GPU embedded in the vast majority of modern processors is a good way to reduce the price of and entry level system, as indeed is choosing Linux for your OS. Your performance is not going to match that of a system with a discrete GPU but with the newer GPU cores available you will be doing much better than the old days of the IGP. The first portion of Phoronix's review of the Skylake GPU covers the various versions of driver you can choose from while the rest compares Kaveri, Godavari, Haswell and Broadwell to the new HD530 on SkyLake CPUs. Currently the Iris Pro 6200 present on Broadwell is still the best for gaming, though the A10-7870K Godavari performance is also decent. Consider one of those two chips now, or await Iris Pro's possible arrival on a newer socketed processor if you are in no hurry.
"Intel's Core i5 6600K and i7 6700K processors released earlier this month feature HD Graphics 530 as the first Skylake graphics processor. Given that Intel's Open-Source Technology Center has been working on open-source Linux graphics driver support for over a year for Skylake, I've been quite excited to see how the Linux performance compares for Haswell and Broadwell as well as AMD's APUs on Linux."

AMD's Godavari architecture is the last one based on Bulldozer, which will hold the company's product stack over until their Zen architecture arrives in 2016. The A10-7870K was added a month ago, with a 95W TDP at a MSRP of $137 USD. This involved a slight performance bump of +200 MHz at its base frequency, but a +100 MHz higher Turbo than its predecessor when under high load. More interesting, it does this at the same TDP and the same basic architecture.
Remember that these are AMD's benchmarks.
The refresh has been expanded to include the A8-7670K. Some sites have reported that this uses the Excavator architecture as seen in Carrizo, but this is not the case. It is based on Steamroller. This product has a base clock of 3.6 GHz with a Turbo of up to 3.9 GHz. This is a +300 MHz Base and +100 MHz Turbo increase over the previous A8-7650K. Again, this is with the same architecture and TDP. The GPU even received a bit of a bump, too. It is now clocked at 757 MHz versus the previous generation's 720 MHz with all else equal, as far as I can tell. This should lead to a 5.1% increase in GPU compute throughput.
The A8-7670K just recently launched for an MSRP of $117.99. This 20$ saving should place it in a nice position below the A10-7870K for mainstream users.

If you are running an ASUS FM2+ board and you want to install the shiny new AMD A10-7870K Godavari processor then it is time to fire up either the ASUS USB BIOS Flashback or ASUS EZ Update tools. Below is a list of all of UEFI versions for all compatible motherboards which you will need to update to in order to boot the new processor. If you do not see your motherboard on the list then it is likely it will not support the new processor, keep an eye on the relevant page on ASUS for more information.
Gigabyte has also release updates to support the new APU, head to their downloads page and search for the model of motherboard you are currently using for the latest UEFI BIOS to flash to.

MSI has revealed a new FM2+ motherboard lineup with support for upcoming AMD Godavari processors, further indicating the launch of these new CPUs will be very soon though no official announcement has yet been made by AMD.
As reported back in January when the lineup allegedly leaked the new Godavari SKUs feature higher clocks on both processor and, more significantly, in GPU cores in upcoming APUs like the rumored 8850K. MSI states that "these new models are available in ATX, micro-ATX, and mini-ATX form factors and are backwards compatible with FM2 processors (Kaveri, Richland, Trinity, 6000 and 5000 series)", so it makes sense to consider these new models for future compatibility if shopping for an FM2 motherboard today. It remains to be seen if vendors will offer support for Godavari through BIOS updates, though it does at least seem likely.
For those interested here is the list of new MSI AMD FM2+/FM2 motherboard models:
- A68HM-E33 V2
- A88XM-E45 V2
- A78M-E35 V2
- A88XM-P33 V2
- A78M-E45 V2
- A88X-G41 PC Mate V2
- A88XM-E35 V2
- A88XI AC V2
The familiar Military Class 4 and OC Genie 4 branding is visible across the lineup, and the new models also feature "a rich blend of features and technologies, such as onboard LAN, PCI Express 3.0 x16, SATA 6Gb/s, USB 3.0 and multiple display support".
Some Fresh Hope for 2016
EDIT 2015-05-07: A day after the AMD analyst meeting we now know that the roadmaps delivered here are not legitimate. While some of the information is likely correct on the roadmaps, they were not leaked by AMD. There is no FM3 socket, rather AMD is going with AM4. AMD will be providing more information throughout this quarter about their roadmaps, but for now take all of this information as "not legit".
SH SOTN has some eagle eyes and spotted the latest leaked roadmap for AMD. These roadmaps cover both mobile and desktop, from 2015 through 2016. There are obviously quite a few interesting tidbits of information here.
On the mobility roadmap we see the upcoming release of Carrizo, which we have been talking about since before CES. This will be the very first HSA 1.0 compliant part to hit the market, and AMD has done some really interesting things with the design in terms of performance, power efficiency, and die size optimizations. Carrizo will span the market from 15 watts to 35 watts TDP. This is a mobile only part, but indications point to it being pretty competent overall. This is a true SOC that will support all traditional I/O functions of older standalone southbridges. Most believe that this part will be manufactured by GLOBALFOUNDIRES on their 28 nm HKMG process that is more tuned to AMD's APU needs.
Carrizo-L will be based on the Puma+ architecture and will go from 10 watts to 15 watts TDP. This will use the same FP4 BGA connection as the big Carrizo APU. This should make these parts more palatable for OEMs as they do not have to differentiate the motherboard infrastructure. Making things easier for OEMs will give more reasons for these folks to offer products based on Carrizo and Carrizo-L APUs. The other big reason will be the GCN graphics compute units. Puma+ is a very solid processor architecture for low power products, but these parts are still limited to the older 28 nm HKMG process from TSMC.
One interesting addition here is that AMD will be introducing their "Amur" APU for the low power and ultra-low power markets. These will be comprised of four Cortex-A57 CPUs combined with AMD's GCN graphics units. This will be the first time we see this combination, and the first time AMD has integrated with ARM since ATI spun off their mobile graphics to Qualcomm under the "Adreno" branding (anagram for "Radeon"). What is most interesting here is that this APU will be a 20 nm part most likely fabricated by TSMC. This is not to say that Samsung or GLOBALFOUNDRIES might be producing it, but those companies are expending their energy on the 14 nm FinFET process that will be their bread and butter for years to come. This will be a welcome addition to the mobile market (tablets and handhelds) and could be a nice profit center for AMD if they are able to release this in a timely manner.
2016 is when things get very interesting. The Zen x86 design will dominate the upper 2/3 of the roadmap. I had talked about Zen when we had some new diagram leaks yesterday, but now we get to see the first potential products based off of this architecture. In mobile it will span from 5 watts to 35 watts TDP. The performance and mainstream offerings will be the "Bristol Ridge" APU which will feature 4 Zen cores (or one Zen module) combined with the next gen GCN architecture. This will be a 14nm part, and the assumption is that it will be GLOBALFOUNDRIES using 14nm FinFET LPP (Low Power Plus) that will be more tuned for larger APUs. This will also be a full SOC.
The next APU will be codenamed "Basilisk" that will span the 5 watt to 15 watt range. It will be comprised of 2 Zen cores (1/2 of a Zen module) and likely feature 2 to 4 MB of L3 cache, depending on power requirements. This looks to be the first Skybridge set of APUs that will share the same infrastructure as the ARM based Amur SOC. FT4 BGA is the basis for both the 2015 Amur and 2016 Basilisk SOCs.
Finally we have the first iteration of AMD's first ground up implementation of ARM's ARMv8-A ISA. The "Styx" APU features the new K12 CPU cores that AMD has designed from scratch. It too will feature the next generation GCN units as well as share the same FT4 BGA connection. Many are anxiously watching this space to see if AMD can build a better mousetrap when it comes to licensing the ARM ISA (as have Qualcomm, NVIDIA, and others).
2015 shows no difference in the performance desktop space, as it is still serviced by the now venerable Piledriver based FX parts on AM3+. The only change we expect to see here is that there will be a handful of new motherboard offerings from the usual suspects that will include the new USB 3.1 functionality derived from a 3rd party controller.
Mainstream and Performance will utilize the upcoming Godavari APUs. These are power and speed optimized APUs that are still based on the current Kaveri design. These look to be a simple refresh/rebadge with a slight performance tweak. Not exciting, but needs to happen for OEMs.
Low power will continue to be addressed by Beema based APUs. These are regular Puma based cores (not Puma+). AMD likely does not have the numbers to justify a new product in this rather small market.
2016 is when things get interesting again. We see the release of the FM3 socket (final proof that AM3+ is dead) that will house the latest Zen based APUs. At the top end we see "Summit Ridge" which will be composed of 8 Zen cores (or 2 Zen modules). This will have 4 MB of L2 cache and 16 MB of L3 cache if our other leaks are correct. These will be manufactured on 14nm FinFET LPE (the more appropriate process product for larger, more performance oriented parts). These will not be SOCs. We can expect these to be the basis of new Opterons as well, but there is obviously no confirmation of that on these particular slides. This will be the first new product in some years from AMD that has the chance to compete with higher end desktop SKUs from Intel.
From there we have the lower power Bristol Ridge and Basilisk APUs that we already covered in the mobile discussion. These look to be significant upgrades from the current Kaveri (and upcoming Godavari) APUs. New graphics cores, new CPU cores, and new SOC implementations where necessary.
AMD will really be shaking up the game in 2016. At the very least they will have proven that they can still change up their game and release higher end (and hopefully competitive) products. AMD has enough revenue and cash on hand to survive through 2016 and 2017 at the rate they are going now. We can only hope that this widescale change will allow AMD to make some significant inroads with OEMs on all levels. Otherwise Intel is free to do what they want and what price they want across multiple markets.

This morning DigiTimes is reporting on a unconfirmed rumour that AMD's new APU, Godavari, will be arriving towards the end of May of this year. This goes along with the leak that WCCFtech reported on this weekend, they have information that the chip will be a Kaveri design with up to four Steamroller cores, a GCN 1.1 base GPU with up to 512 stream processors and a dual-channel DDR3 memory in an FM2+ socket. If their information is accurate you can expect to see models with 65W or 95W TDPs and boost clocks in the 4GHz range depending on the model. Also worth noting is the rumour that AMD has placed orders with ASMedia Technology for USB 3.1 controller ICs for release in September.
"AMD will launch Godavari series APUs at the end of May to compete with Intel's Broadwell and Skylake platforms, according to Taiwan-based supply chain makers."
