Tagged: Zen, opteron, amd
We're beginning to see how the Zen architecture will affect AMD's entire product stack. This news refers to their Opteron line of CPUs, which are intended for servers and certain workstations. They tend to allow lots of memory, have lots of cores, and connect to a lot of I/O options and add-in boards at the same time.
In this case, Zen-based Opterons will be available in two, four, sixteen, and thirty-two core options, with two threads per core (yielding four, eight, thirty-two, and sixty-four threads, respectively). TDPs will range between 35W and 180W. Intel's Xeon E7 v4 goes up to 165W got 24 cores (on Broadwell-EX) so AMD has a little more headroom to play with for those extra eight cores. That is obviously a lot, and it should be, again, good for cloud applications that can be parallelized.
As for the I/O side of things, the rumored chip will have 128 PCIe 3.0 lanes. It's unclear whether that is per socket, or total. Its wording sounds like it is per-CPU, although much earlier rumors have said that it has 64 PCIe lanes per socket with dual-socket boards available. It will also support sixteen 10-Gigabit Ethernet connections, which, again, is great for servers, especially with virtualization.
These are expected to launch in 2017. Fudzilla claims that “very late 2016” is possible, but also that it will launch after high-end desktop, which are expected to be delayed until 2017.

AMD has just unveiled their entire RX line of graphics cards at E3 2016's PC Gaming Show. It was a fairly short segment, but it had a few interesting points in it. At the end, they also gave another teaser of Summit Ridge, which uses the Zen architecture.
First, Polaris. As we know, the RX 480 was going to bring >5 TFLOPs at a $199 price point. They elaborated that this will apply to the 4GB version, which likely means that another version with more VRAM will be available, and that implies 8GB. Beyond the RX 480, AMD has also announced the RX 470 and RX 460. Little is known about the 470, but they mentioned that the 460 will have a <75W TDP. This is interesting because the PCIe bus provides 75W of power. This implies that it will not require any external power, and thus could be a cheap and powerful (in terms of esports titles) addition to an existing desktop. This is an interesting way to use the power savings of the die shrink to 14nm!
They also showed off a backpack VR rig. They didn't really elaborate, but it's here.
As for Zen? AMD showed the new architecture running DOOM, and added the circle-with-Zen branding to a 3D model of a CPU. Zen will be coming first to the enthusiast category with (up to?) eight cores, two threads per core (16 threads total).
The AMD Radeon RX 480 will launch on June 29th for $199 USD (4GB). None of the other products have a specific release date.

Intel's recent restructure had a much broader impact than I originally believed. Beyond the large number of employees who will lose their jobs, we're even seeing it affect other areas of the industry. Typically, ASUS releases their ZenPhone line with x86 processors, which I assumed was based on big subsidies from Intel to push their instruction set into new product categories. This year, ASUS chose the ARM-based Qualcomm Snapdragon, which seemed to me like Intel decided to stop the bleeding.
That brings us to today's news. After over 27 years at Intel, James Reinders accepted the company's early retirement offer, scheduled for his 10001st day with the company, and step down from his position as Intel's High Performance Computing Director. He worked on the Larabee and Xeon Phi initiatives, and published several books on parallelism.
According to his letter, it sounds like his retirement offer was part of a company-wide package, and not targeting his division specifically. That would sort-of make sense, because Intel is focusing on cloud and IoT. Xeon Phi is an area that Intel is battling NVIDIA for high-performance servers, and I would expect that it has potential for cloud-based applications. Then again, as I say that, AWS only has a handful of GPU instances, and they are running fairly old hardware at that, so maybe the demand isn't there yet.

Bad news upgraders, neither AMD nor Intel will be launching their new CPUs until the beginning of next year. Both AMD's Zen and Intel's Kaby Lake have now been delayed instead of launching in Q4 and Q3 of this year respectively. DigiTimes did not delve into the reasons behind the delay in AMD's 14nm GLOBALFOUNDRIES (and Samsung) sourced Zen but unfortunately the reasons beind Intel's delay are all too clear. With large stockpiles of Skylake and Haswell processors and systems based around them sitting in the channel, AMD's delay creates an opportunity for Intel and retailers to move that stock. Once Kaby Lake arrives the systems will no longer be attractive to consumers and the prices will plummet.
Here is to hoping AMD's delay does not imply anything serious, though the lack of a new product release at a time which traditionally sees sales increase is certainly going to hurt their bottom line for 2016.
"With the delays, the PC supply chain will not be able to begin mass production for the next-generation products until November or December and PC demand is also unlikely to pick up until the first quarter of 2017."

Yesterday, Intel launched eleven SKUs of Xeon processors that are based on Broadwell-EX. While I don't follow this product segment too closely, it's a bit surprising that Intel launched them so close to consumer-level Broadwell-E. Maybe I shouldn't be surprised, though.
These processors scale from four cores up to twenty-four of them, with HyperThreading. They are also available in cache sizes from 20MB up to 60MB. With Intel's Xeon naming scheme, the leading number immediately after the E7 in the product name denotes the number of CPUs that can be installed in a multi-socket system. The E7-8XXX line can be run in an eight-socket motherboard, while the E7-4XXX models are limited to four sockets per system. TDPs range between 115W and 165W, which is pretty high, but to be expected for a giant chip that runs at a fairly high frequency.
Intel Xeon E7 v4 launched on June 6th with listed prices between $1223 to $7174 per CPU.

Tagged: hsa 1.1, hsa
The HSA Foundation released version 1.1 of their specification, which focuses on “multi-vendor” compatibility. In this case, multi-vendor doesn't refer to companies that refused to join the HSA Foundation, namely Intel and NVIDIA, but rather multiple types of vendors. Rather than aligning with AMD's focus on CPU-GPU interactions, HSA 1.1 includes digital signal processors (DSPs), field-programmable gate arrays (FPGAs), and other accelerators. I can see this being useful in several places, especially on mobile, where cameras, sound processors, and CPU cores, and a GPU regularly share video buffers.
That said, the specification also mentions “more efficient interoperation with non-HSA compliant devices”. I'm not quite sure what that specifically refers to, but it could be important to keep an eye on for future details -- whether it is relevant for Intel and NVIDIA hardware (and so forth).
Charlie, down at SemiAccurate, notes that HSA 1.1 will run on all HSA 1.0-compliant hardware. This makes sense, but I can't see where this is explicitly mentioned in their press release. I'm guessing that Charlie was given some time on a conference call (or face-to-face) regarding this, but it's also possible that he may be mistaken. It's also possible that it is explicitly mentioned in the HSA Foundation's press blast and I just fail at reading comprehension.
If so, I'm sure that our comments will highlight my error.

You have seen our take on the impressively powerful and extremely expensive i7-6950X but of course we were not the only ones to test out Intel's new top of the line processor. Hardware Canucks focused on the difference between the ~$1700 i7-6950X and the ~$1100 i7-6900K. From synthetic benchmarks such as AIDA through gaming at 720p and 1080p, they tested the two processors against each other to see when it would make sense to spend the extra money on the new Broadwell-E chip. Check out what they thought of the chip overall as well as the scenarios where they felt it would be full utilized.
"10 cores, 20 threads, over $1700; Intel's Broadwell-E i7-6950X delivers obscene performance at an eye-watering price. Then there's the i7-6900K which boasts all the same niceties in a more affordable package."

Tagged: Zen, computex 2016, computex, amd
At the end of the AMD Computex 2016 keynote, Lisa Su, President and CEO of the company, announced a few details about their upcoming Zen architecture. This will mark the end of the Bulldozer line of architectures that attempted to save die area by designing cores in pairs, eliminating what AMD projected to be redundancies as the world moved toward multi-core and GPU compute. Zen “starts from scratch” and targets where they now see desktop, server, laptop, and embedded devices heading.
They didn't really show a whole lot at the keynote. They presented an animation that was created and rendered on the new architecture. I mean, okay, but that's kind-of like reviewing a keyboard by saying that you used it to type the review. It's cool that you have sample silicon available to use internally, but we understand that it physically works.
That said, Lisa Su did say some hard numbers, which should be interesting for our readers. AMD claims that Zen has 40% higher IPC from their previous generation (which we assume is Excavator). It will be available for desktop with eight cores, two threads per core, on their new AM4 platform. It also taped out earlier this year, with wide sampling in Q3.
I'm curious how it will end up. The high-end CPU market is a bit... ripe for the picking these days. If AMD gets close to Intel in performance, and offers competitive prices and features alongside it, then it would make sense for enthusiast builds. We'll need to wait for benchmarks, but there seems to be low-hanging fruit.
Bristol Ridge Takes on Mobile: E2 Through FX
It is no secret that AMD has faced an uphill battle since the release of the original Core 2 processors from Intel. While stayed mostly competitive through the Phenom II years, they hit some major performance issues when moving to the Bulldozer architecture. While on paper the idea of Chip Multi-Threading sounded fantastic, AMD was never able to get the per thread performance up to expectations. While their CPUs performed well in heavily multi-threaded applications, they just were never seen in as positive of a light as the competing Intel products.
The other part of the performance equation that has hammered AMD is the lack of a new process node that would allow it to more adequately compete with Intel. When AMD was at 32 nm PD-SOI, Intel had introduced its 22nm TriGate/FinFET. AMD then transitioned to a 28nm HKMG planar process that was more size optimized than 32nm, but did not drastically improve upon power and transistor switching performance.
So AMD had a double whammy on their hands with an underperforming architecture and limitted to no access to advanced process nodes that would actually improve their power and speed situation. They could not force their foundry partners to spend billions on a crash course in FinFET technology to bring that to market faster, so they had to iterate and innovate on their designs.
Bristol Ridge is the fruit of that particular labor. It is also the end point to the architecture that was introduced with Bulldozer way back in 2011.
