More Details Uncovered On AMD’s ZEN Cores
Comments Off on More Details Uncovered On AMD’s ZEN Cores
Our well informed industry sources have shared a few more details about the AMD’s 2016 Zen cores and now it appears that the architecture won’t use the shared FPU like Bulldozer.
The new Zen uses a SMT Hyperthreading just like Intel. They can process two threads at once with a Hyperthreaded core. AMD has told a special few that they are dropping the “core pair” approach that was a foundation of Bulldozer. This means that there will not be a shared FPU anymore.
Zen will use a scheduling model that is similar to Intel’s and it will use competitive hardware and simulation to define any needed scheduling or NUMA changes.
Two cores will still share the L3 cache but not the FPU. This because in 14nm there is enough space for the FPU inside of the Zen core and this approach might be faster.
We mentioned this in late April where we released a few details about the 16 core, 32 thread Zen based processor with Greenland based graphics stream processor.
Zen will apparently be ISA compatible with Haswell/Broadwell style of compute and the existing software will be compatible without requiring any programming changes.
Zen also focuses on a various compiler optimisation including GCC with target of SPECint v6 based score at common compiler settings and Microsoft Visual studio with target of parity of supported ISA features with Intel.
Benchmarking and performance compiler LLVM targets SPECint v6 rate score at performance compiler settings.
We cannot predict any instruction per clock (IPC improvement) over Intel Skylake, but it helps that Intel replaced Skylake with another 14nm processor in later part of 2016. If Zen makes to the market in 2016 AMD might have a fighting chance to narrow the performance gap between Intel greatest offerings.

AMD Misses Again
Fabless chipmaker AMD has come up with a mixed set of results for the second quarter. The company managed to make as much cash as the cocaine nose jobs of Wall Street expected, but missed revenue expectations.
In fact its revenues were below the psychologically important billion figure at $942 million.
We knew it was going to be bad. Last week we were warned that the results would be flat. The actual figure was $942m, an 8.5 per cent sequential decline and a 34.6 per cent drop from the same period a year ago.
As you might expect, there are some measures of this not being AMD’s fault. The company is almost entirely dependent on PC sales. Not only have these fallen but don’t look like they are going to pick up for a while.
AMD’s Computing and Graphics division reported revenue of $379m, which was down 54.2 per cent, year-on-year. Its operating loss was $147m, compared to a $6m operating loss for last year’s quarter.
Lisa Su, AMD president and CEO, in a statement said that strong sequential revenue growth in AMD’s enterprise, embedded, and semi-custom segment and channel business was not enough to offset near-term problems in its PC processor business. This was due to lower than expected consumer demand that impacted sales to OEMs, she said.
“We continue to execute our long-term strategy while we navigate the current market environment. Our focus is on developing leadership computing and graphics products capable of driving profitable share growth across our target markets,” she added.
In the semi-custom segment, AMD makes chips for video game consoles such as the Nintendo Wii U, Microsoft Xbox One, and Sony PlayStation 4 consoles. That segment did reasonably well, up 13 percent from the previous quarter but down 8 percent from a year ago.
But AMD’s core business of processors and graphics chips fell 29 percent from the previous quarter and 54 percent from a year ago. AMD said it had decreased sales to manufacturers of laptop computers.
Figures like this strap a large target on AMD’s back with a sign saying “take me over” but AMD is not predicting total doom yet.
For the third quarter, AMD expects revenue to increase 6 percent, plus or minus 3 percent, sequentially, which is a fairly conservative outlook given the fact that Windows 10 is expected to push a few sales its way.
AMD supplies chips to the Nintendo Wii U, Microsoft Xbox One, and Sony PlayStation 4 consoles and these seem to be going rather well.
Should Investors Dump AMD?
If you have any old AMD shares lying around you might like to sell them as fast as you can, according to the bean counters at Goldman Sachs.
Despite the fact that the company is doing rather well, and its share price is has gone up rapidly over recent months, Goldman Sach analysts claim that the writing is on the wall for AMD. It thinks that AMD shares will be worth just $2.50 soon. The stock’s 50-day moving average is currently $2.98.
The company said that while AMD could clean up in the gaming market even if you take those figures into account the stock is trading at 22 times its 2014 CY EPS estimate. In other words the company’s core PC business is still shagged and still will generate 45 per cent of the company’s 2013 revenue.
“We therefore believe this recent move in the stock is just the latest in a long history of unsustainable rallies, and we are downgrading the stock to Sell. We believe the current multiple is unjustified for any company with such significant exposure to the secularly declining PC market,” the firm’s analyst wrote.
Analysts at Sanford C. Bernstein think that the share price will settle on $2.00 and FBR Capital Markets thinks $3.00. In other words if you want to know what is really happening at AMD you might as well ask the cat, than any Wall Street expert.
AMD’s Richland Coming In June
Richland is set to replace AMD’s Virgo platform, powered by Trinity processors, and this change will happen in June 2013, most likely coinciding with Computex 2013.
AMD has just launched the first batch of Richland mobile APUs and we still have to see some notebook designs hitting the market. We wrote about mobile Richland APUs.
As of late last year Desktop Richland was always set to launch in June 2013 and the fastest of them is the A10 6800K, clocked at 4.1GHz and 4.4 with Turbo. It also features Radeon HD 8670D graphics that run at 844 MHz. This is the fastest Richland part and it comes unlocked, ready to replace the current AMD A10 5800K. In Europe, the A10 5800K currently sells for 112, while in US the same CPU sells for $129.00 (boxed).
The alpha dog A10 6800K is followed by A10 6700, A8 6600K (Unlocked) and A8 6500. AMD has a mix of 100W and 65W quad-core Richland desktop SKUs. There will be a single A6 6400K (Unlocked) SKU and the A4 6300, both dual-cores with 65W TDP.
Production ready samples were churned out in late January, while volume production is scheduled for late March 2013. The announcement was always scheduled for June 2013 and Richland last through most of 2013, until Kaveri with 28nm Steamroller comes on line.
AMD Goes Richland
There have been more than enough leaks dealing with Richland, AMD’s successor to the Trinity powered Virgo platform, and we even had a chance to see some leaks regarding its successor, codenamed Kaveri. As you may already know, Richland is planned to last through 2013 and it is clear that this is very important chip for AMD.
Based on the Piledriver architecture and built using 32nm technology, Richland will feature an integrated GPU that will be upgraded to Radeon HD 8000 series, a generation ahead of Trinity. As you know, there has been a lot of leaks regarding the Richland parts and the quad-core A10-6800K with Radeon HD 8670D graphics is expected to pack quite a punch. Best of all, Richland will still use the same FM2 socket.
According to our sources, the NDA will be lifted on 12th of March, 8am EST, and we are sure that we will see at least a couple of reviews as well as some additional info regarding the price and the availability date.
AMD Releases Vishera
Although it was detailed back in August last year, AMD has just now officially released its new “affordable” Vishera based FX-4130 quad-core socket AM3+ CPU.
The new CPU is part of AMD’s 4100-series and is based on Vishera core design with four Piledriver cores. It works at 3.8GHz base clock and can “turbo” up to 3.9GHz. It packs 4MB of L2 and 4MB of L3 cache and has a 125W TDP.
According to the slide over at Xbitlabs.com, the FX-4130 replaces the FX-4100 with the same US $101 price but should provide between 3 and 9 percent more performance.
As things get better with Globalfoundries and their 32nm process technology, AMD is expected to introduce new models based on cut-down versions of Vishera, according to the report.
AMD’s Roadmap Leaked
According to the latest AMD desktop roadmap, published by DonanimHaber, the Steamroller architecture could be delayed, which means Piledriver cores will power AMD’s third-generation APUs.
So what does this mean for consumers? Well, Richland APUs might not be quite as good as expected. AMD could optimize the x86 cores and go for more powerful graphics, but it’s hard to get excited about the next generation.
Vishera parts will also stick to Piledriver cores, backed by discreet Radeon 7xxx and 8xxx series graphics. However, we will see a new architecture in the low end. Kabini is apparently on track to launch next year, with Jaguar cores, refreshed graphics and an all new system-on-chip version, with an integrated on-chip Fusion controller hub (FCH).
What’s more, AMD will also offer quad-core Kabini parts, and who could say no to a dirt cheap E-series APU with four cores, good graphics and a ridiculous TDP?
AMD Makes More Cuts
There have been some rumors that AMD plans to drop prices on its older generation APUs as well as some AM3 Athlon II CPUs and as of yesterday, the new price list confirmed those cuts. Unfortunately the price cuts are not that impressive on the FM1 side but some AM3 Athlon II CPUs have seen a price reduction of over 30 percent.
The full list includes a total of six A-Series APUs and twelve AM3 Athlon II CPUs. The most impressive price cut in the A-Series was on the A4-3300 APU for 21.7 percent, or from US $46 down to US $36. The flagship A8-3870K got cut down by 9.9 percent while A6-3670K was cut down by far less impressive 3.7 percent.
The most impressive price cuts on the AM3 Athlon II side is on the Athlon II X4 640 and the Athlon II X2 265. The Athlon II X4 640 got cut down from US $98 to US $67, or 31.6 percent, while Athlon II X2 265 got cut down from US $69 to US $48, or 30.4 percent.
Two Athlon II CPUs, the X3 445 and the X4 638, were removed from the price list as they were most likely discontinued.

AMD Goes Piledriver
AMD has released its Piledriver desktop
processors codenamed Vishera.
AMD showed off Vishera at IDF last month, an overclocked chip running at 5GHz. Now the company has taken the wraps off its eight-core Vishera chip, a processor that it hopes will finally bury memories of its disappointing Bulldozer Zambezi chip.
AMD’s Vishera processors will continue to use Socket AM3+, meaning it is a drop-in upgrade for those customers lumbered with Zambezi processors.
The firm announcing four models all branded with the FX moniker. The low-end Vishera chip is the quad-core FX-4300 clocked at 3.8GHz boosted up to 4.0GHz, with 4MB of Level 3 cache.
The firm has kept feature parity throughout its Vishera FX range aside from core count and total Level 3 cache. Therefore AMD’s six-core FX-6300 still sports the same 1MB of Level 2 cache per core but has a total Level 3 cache of 8MB and is clocked at 3.5GHz that can be boosted up to 4.1GHz.
AMD’s top two Vishera parts, the FX-8320 and FX-8350 sport eight cores and have 8MB of Level 3 cache. The difference between the two chips is their clock frequencies, with the FX-8320 running at 3.5GHz and boosted to 4.0GHz while the FX-8350 is clocked at 4.0GHz and is boosted to 4.2GHz.
The firm’s decision to clock its FX-8320 and FX-8350 so closely is largely academic, as all Vishera chips feature an unlocked multiplier. AMD even plays up the overclockability of Vishera and touts 5GHz as being reachable with water cooling. Insiders have even said it can reach 5GHz with strong air cooling.
As for AMD’s Piledriver architecture, the firm claims it offers improved branch prediction and improvements to Level 2 cache efficiency and scheduling. Overall the company is sticking to its longstanding line that Vishera is a 15 percent performance increase over Bulldozer, and while that might well be true, Bulldozer was so far behind its competition in single-threaded performance that a 15 percent gain is needed simply to achieve parity, let alone a lead.
AMD Makes Cuts
AMD has cut its third quarter revenue and gross margin forecasts citing weak demand.
AMD’s lacklustre Bulldozer processor line has left the firm desperately trying to compete with Intel in the desktop market while its more impressive accelerated processor unit (APU) range has been rebuffed by Intel’s multi-million dollar ultrabook marketing push. Now AMD has revised down its estimate of third quarter revenues, which it says will be around 10 percent lower than the previous quarter.
Even more worrying for AMD is its lower forecast for gross margin, the difference between selling an item and the cost to make it, down from 44 percent to 31 percent. Effectively AMD said its cost of doing business has risen considerably higher, although it laid most of the blame on an $100m inventory writedown.
AMD couldn’t avoid admitting the blindingly obvious and said that its writedown of inventory was due to “lower anticipated future demand for certain products”. The firm has suffered through a disappointing 2012, and earlier this year it announced a $580m loss back in April.
