AMD has announced that its A8-7600 midrange Kaveri that it initially launched in mid-January has slipped and won’t be available to retail customers until the second half of the year. That’s a substantial delay from the company’s initial position; AMD originally expected to have the A8-7600 in channel by the end of the first quarter. Normally a mid-range part delay wouldn’t be big news, but AMD took the unusual step of positioning the A8-7600 as a launch part rather than focusing entirely on the high end of its nascent product family.
The reason for this shift was obvious: Because the Steamroller architecture doesn’t scale particularly well at high clock speeds. The modest 45W A8-7600 offered far better performance than AMD’s previous OEM-only A8-6500T, while the configurable TDP option let users choose if they wanted to run the chip at 45W, 65W, or “Unlimited.” In practical terms, this resulted in a Turbo Core frequency of 3.4, 3.6, or the full 3.8GHz (on average).
With a maximum clock that approached the A10-7850K’s 4.0GHz, a 384-core GPU, and a price tag of just $129, the 45W A8-7600 offered 80-90% of the A10-7850K’s performance for 70% the price. It’s well positioned to take advantage of the surge of interest into Steam Machines or similar systems. According to AMD, the chip is “on track” (the meaning of that term is highly debatable) for OEM introduction in Q2, with retail availability coming in the back half of the year.
What does this mean for mobile Kaveri?
The big question is whether this delay points to problems with AMD’s lower power laptop chips. When AMD and Intel bin processors, they test the chips over a range of operating frequencies and voltages. Two different chips off the same wafer could conceivably run at the same clock speed, but one core draws 45W at 3.5GHz using 1.2v while the other chip draws 65W at 3.5GHz and requires 1.4v. A third core might be capable of running at 3.5GHz in 35W on just 1.1v. These three chips get separated into three different market segments — the 35W is used for mobile, the 45W chip goes into small form factor desktops, and the 65W chip is a conventional desktop CPU.
Typically, the lower power bands are more difficult to reach and therefore cost more money; Intel has spent several years retooling itself to focus more on these segments and still typically charges more money for its lowest-power processors. It’s possible that AMD has hit a bump in its overall product ramp — we won’t know more until we see the company’s mobile plans and roadmap for the rest of the year, which should happen in the not-too-distant future.
The other possibility is that AMD has had trouble getting capacity at GlobalFoundries. AMD initially announced a $1.5B wafer supply agreement with GF in 2013, but then only purchased $1.1B worth of equipment. It announced that it would not pay a penalty for this. Granted, GF may have felt magnanimous — it took AMD to the cleaners for nearly $800M in 2012 — but there may have also been some cutbacks in the amount of wafer capacity dedicated to AMD. In fact, AMD has stated that it only expects to purchase $1.2B worth of wafers from GF in 2014, despite moving some semi-custom APU business to its foundry partner in 2014.
AMD, of course, is not the only company to have been caught out by product ramp difficulty. Intel’s Broadwell has reportedly been pushed back to the end of the year and Chipzilla is planning to cut some 5% of its total workforce in 2014. The company announced the closure of a Costa Rica facility yesterday as part of that process. The A8-7600 should still occupy a unique price and performance niche when it finally launches, but pushing it off another four to five months leaves AMD’s low-end anchored by two-year-old Richland and Trinity hardware.
Update (4/11/2014): We’ve spoken to trusted sources who have confirmed that the A8-7600 is in testing at multiple OEMs for a Q2 introduction. This implies that the original launch window and the meaning of “Availability” was poorly communicated in January but that there’s no underlying problem with the chip (or, by extension, with the mobile Kaveri ramp).
Microsoft Corp released its final security updates for Windows XP and Office 2003 April 8 as security experts warned users that they could soon be prime targets for cyber attacks if they do not abandon the products.Security experts advise consumers and businesses to either replace computers running Windows XP or upgrade to modern versions of Microsoft's software within the next month because they will no longer be protected from newly discovered threats after the middle of May. Microsoft automatically rolls out new security updates on the second Tuesday of each month, which is known as "Patch Tuesday," a day when they also publish technical details on the security bugs they are fixing. The next Patch Tuesday is May 13. Security experts say they believe hackers will study that data and "reverse engineer" the May Patch Tuesday software updates to identify ways to attack computers running Windows XP, along with Office 2003, which will no longer receive patches from Microsoft. "Attackers will use this as an accelerator. It's an easier way to get at machines," said Wolfgang Kandek, chief technology officer with cybersecurity firm Qualys Inc. Microsoft wants users to move to more modern versions of the operating system partly because it has incorporated new security features into the software over the past decade that make it far more effective in thwarting cyber attacks. The world's largest software maker first warned that it was planning to end support for Windows XP in 2007, but security firms estimate that 15 to 25 percent of the world's PCs still run on the version of the operating system that was released in October 2001. Only about a third of the world's 2.2 million ATMs which use the system have been upgraded to newer operating systems, according to NCR, one of the biggest ATM makers.
