AMD has certainly gone about doing things in a slightly different manner than we are used to. Today they announced their two latest APUs which will begin shipping in the first half of 2015. These APUs are running at AMD and are being validated as we speak. AMD did not release many details on these products, but what we do know is pretty interesting.
Carrizo is based on the latest iteration of AMD’s CPU technology. Excavator is the codename for these latest CPU cores, and they promise to be smaller and more efficient than the previous Steamroller core which powers the latest Kaveri based APUs. Carrizo-L is the lower power variant which will be based on the Puma+ core. The current Beema APU is based on the Puma architecture.
Roadmaps show that the Carrizo APUs will be 28 nm products, presumably fabricated by GLOBALFOUNDRIES. Many were hoping that AMD would make the jump to 20 nm with this generation of products, but that does not seem to be the case. This is not surprising due to the limitations of that particular process when dealing with large designs that require a lot of current. AMD will likely be pushing for 16 nm FinFET for the generation of products after Carrizo.
The big Carrizo supposedly has a next generation GCN unit. My guess here is that it will use the same design as we saw with the R9 285. That particular product is a next generation unit that has improved efficiency. AMD did not release how many GCN cores will be present in Carizzo, but it will be very similar to what we see now with Kaveri. Carrizo-L will use the same GCN units as the previous generation Beema based products.
I believe AMD has spent a lot more time hand tuning Excavator instead of relying on a lot of automated place and route. This should allow them to retain much of the performance of the part, all the while cutting down on transistor count dramatically. Some rumors that I have seen point to each Excavator module being 40% smaller than Steamroller. I am not entirely sure they have achieved that type of improvement, but more hand layout does typically mean greater efficiency and less waste. The downside to hand layout is that it is extremely time and manpower intensive. Intel can afford this type of design while AMD has to rely more on automated place and route.
Carrizo will be the first HSA 1.0 compliant SOC. It is in fact an SOC as it integrates the southbridge functions that previously had been handled by external chips like the A88X that supports the current Kaveri desktop APUs. Carrizo and Carrizo-L will also share the same infrastructure. This means that motherboards that these APUs will be soldered onto are interchangeable. One motherboard from the partner OEMs will be able to address multiple markets that will see products range from 4 watts TDP up to 35 watts.
Finally, both APUs feature the security processor that allows them access to the ARM TrustZone technology. This is a very small ARM processor that handles the secure boot partition and handles the security requests. This puts AMD on par with Intel and their secure computing solution (vPro).
These products will be aimed only at the mobile market. So far AMD has not announced Carrizo for the desktop market, but when they do I would imagine that they will hit a max TDP of around 65 watts. AMD claims that Carrizo is one of the biggest jumps for them in terms of power efficiency. A lot of different pieces of technology have all come together with this product to make them more competitive with Intel and their process advantage. Time will tell if this is the case, but for now AMD is staying relevant and pushing their product releases so that they are more consistently ontime.

Last month, Josh wrote about Intel's Q3 earnings report. The company brought in $14.55 billion USD, of which they could keep $3.31 billion. Their PC group is responsible for $9 billion of that revenue and $4.12 billion of that profit, according to the Wall Street Journal. On the other hand, their mobile division is responsible for about $1 million – and it took over a billion to get that million. This has been the trend for quite some time now, as Intel pushes their square battering ram into the mobile and tablet round hole. Of course, these efforts could benefit the company as a whole, but they cannot show that in a quarterly, per-division report.
And so we hear rumors that Intel intends to combine their mobile and PC divisions, which Chuck Mulloy, an Intel spokesperson, later confirmed in the same article. The new division, allegedly called the “Client Computing” group in an internal email that was leaked to the Wall Street Journal, will handle the processors for mobile devices but, apparently, not the wireless modem chipsets; those will allegedly be moved to a “wireless platform research and development organization”.
At face value, this move should allow Intel to push for mobile even more aggressively, while simultaneously reducing the pressure from investors to give up and settle for x86 PCs. Despite some differences, this echos a recent reorganization by AMD, where they paired-up divisions that were doing well with divisions that were struggling to make a few average divisions that were each treading water, at least on paper.
The reorganization is expected to complete by the end of Q1 2015, but that might not be a firm deadline.

Intel's smartphone and tablet divisions are being rolled up under Kirk Skaugen's PC Business division in what was described as an attempt to "accelerate Intel's opportunity in the marketplace". This is definitely needed as Intel is having great difficulties garnering market share in the mobile industry, the only successes they have had are with larger more expensive tablets. One possible benefit of this merger that was mentioned in the Inquirer's article was Intel's plans to leverage the growing use of LTE in both tablets and laptops, perhaps we shall see a 4G card become far more common in even basic models. Intel implied that they are not planning any layoffs at this point although unless their ultramobile division can pick up the pace it seems inevitable that some will feel the axe. We shall see over the coming year if Intel's focus on low powered silicon can help in their battles against incumbents such as ARM and Qualcomm.
"INTEL HAS ANNOUNCED plans to merge its smartphone and tablet operations with its PC division in a bid to make the two businesses more efficient, and to further compete with rivals in the mobile semiconductor market."

When you use Linux you have a choice as to which file system you wish to use, a choice that never occurs to most Windows users but can spark an argument every bit as vicious as the eternal debate over EMACS versus VIM versus whichever text editor you prefer. There has not been much SSD benchmarking done on alternate files systems until now, Phoronix has benchmarked the Intel 530 series SSD in numerous configurations on Btrfs, EXT4, XFS, and F2FS. With four of the 120GB model available they were able to test the speed of the drives in RAID 0, 1, 5, 6, and 1+0. There is obviously still some compatibility issues as some tests failed to run in certain configurations but overall these drives performed as expected. While the results did not vary widely it is worth reading through their article if you plan on building a high speed storage machine which will run Linux.
"Following the recent Btrfs RAID: Native vs. Mdadm comparison, the dual-HDD Btrfs RAID benchmarks, and four-SSD RAID 0/1/5/6/10 Btrfs benchmarks are RAID Linux benchmarks on these four Intel SATA 3.0 solid state drives using other file-systems -- including EXT4, XFS, and Btrfs with Linux 3.18."

Tagged: ssd, pcie, NVMe, Intel, DC P3500
Since we reviewed the Intel SSD DC P3700, many of you have been drooling over the idea of an 18-channel NVMe PCIe SSD, even more so given that the P3500 variant was to launch at a $1.50/GB target price. It appears we are getting closer to that release, as the P3500 has been appearing on some web sites in pre-order or out of stock status.
ShopBLT lists the 400GB part at $629 ($1.57/GB), while Antares Pro has an out of stock listing at $611 ($1.53/GB). The other two capacities are available at a similar cost/GB. We were hoping to see an 800GB variant, but it appears Intel has stuck to their initial plan. Here are the part numbers we’ve gathered, for your Googling pleasure:
- 400GB: SSDPEDMX400G401
- 1.2TB: SSDPEDMX012T401
- 2TB: SSDPEDMX020T401
2.5” SFF-8639 (*not SATA*):
- 400GB: SSDPE2MX400G401
- 1.2TB: SSDPE2MX012T401
- 2TB: SSDPE2MX020T401
We did spot a date of December 12th in an Amazon listing, but I wouldn't count that as a solid date, as many of the listings there had errors (like 10 packs for the price of one).

Tagged: Intel, ssd, dc s3500, M.2
Today Intel refreshed their Datacenter Series of SSDs, specifically their DC S3500. We have reviewed this model in the past. It uses the same controller that is present in the S3700, as well as the SSD 730 Series (though it is overclocked in that series).
The full line of Intel Datacenter SSDs (minus the P3700). DC S3500 is just right of center.
Todays refresh includes higher capacities to the S3500, which now include 1.2TB and 1.6TB on the hign end of capacity. This suggests that Intel is stacking 20nm dies as many as 8 to a package. IOPS performance sees a slight penalty at these new higher capacities, while maximum sequentials are a bit higher due to the increased die count.
Also announced was an M.2 version of the S3500. This packaging is limited to only a few capacity points (80GB, 120GB, 340GB), and is p;rimarily meant for applications where data integrity is critical (i.e. ATM's, server boot partitions, etc).
A standard press blast was unavailable, but full specs are listed after the break.
Core M 5Y70 Specifications
Back in August of this year, Intel invited me out to Portland, Oregon to talk about the future of processors and process technology. Broadwell is the first microarchitecture to ship on Intel's newest 14nm process technology and the performance and power implications of it are as impressive as they are complex. We finally have the first retail product based on Broadwell-Y in our hands and I am eager to see how this combination of technology is going to be implemented.
If you have not read through my article that dives into the intricacies of the 14nm process and the architectural changes coming with Broadwell, then I would highly recommend that you do so before diving any further into this review. Our Intel Core M Processor: Broadwell Architecture and 14nm Process Reveal story clearly explains the "how" and "why" for many of the decisions that determined the direction the Core M 5Y70 heads in.
As I stated at the time:
"The information provided by Intel about Broadwell-Y today shows me the company is clearly innovating and iterating on its plans set in place years ago with the focus on power efficiency. Broadwell and the 14nm process technology will likely be another substantial leap between Intel and AMD in the x86 tablet space and should make an impact on other tablet markets (like Android) as long as pricing can remain competitive. That 14nm process gives Intel an advantage that no one else in the industry can claim and unless Intel begins fabricating processors for the competition (not completely out of the question), that will remain a house advantage."
With a background on Intel's goals with Broadwell-Y, let's look at the first true implementation.

At $258 the ASUS X99-A is one of the more affordably priced X99 motherboards on the market and The Tech Report thoroughly tested it to see what, if anything, is lacking. The board still has the "OC Socket" with extra pins which allow the certifiably insane to up their CPU voltage to 1.8V, it retains the M.2 socket, the DDR4 can hit 3000MHz even with all 8 slots populated and three of its six PCIe slots can be used together for SLI or Crossfire. In fact The Tech Report has a very nice illustration showing how the board works with both 28 lane and 40 lane Haswell-E processors. Check out the results of their testing right here.
"Rather than loading up on flashy extras and extraneous accessories, Asus' X99-A motherboard focuses on the basics. It has a sensible spec, loads of builder-friendly features, and a diverse array of powerful tweaking options. Read on to see what makes this our favorite Haswell-E motherboard to date."

For a mere $60 you can get the ASRock D1800M motherboard with a Celeron J1800 installed, or for about $8 more you can get a socketed Sempron 2650 and compatible motherboard. After that it is merely a matter of adding a PSU, RAM and storage and you have a working machine for very little cost. Those were the systems which Hardware Secrets tested out to see which low cost, low powered system made more sense to purchase for light browsing and media consumption. As you would expect the 1Ghz clock advantage that the Celeron enjoys pushed its performance above the Sempron in all tests but 3D Mark but what is interesting is that the performance gap was nowhere near as large a percentage difference as the clock speed. While it is clear that the Celeron runs cooler, quieter and faster the fact that the AMD solution is socketed might sway some buyers decision. Check out the full review if you are interested in working machines that cost less than $200 to assemble.
"Both AMD and Intel recently released new families of low cost, low TDP desktop CPUs. AMD launched the AM1 platform with Sempron and Athlon "Kabini" processors, while Intel released the "Bay Trail-D" Celeron and Pentium CPUs, recognizable by the use of the letter "J" on the model naming. Among the lowest-end models of each family are, respectively, the AMD Sempron 2650, and the Intel Celeron J1800. Let's compare the performance of those CPUs and discover which one is the best buy in the low-end market segment."
