Today Qualcomm took the covers off of an update to the Snapdragon 600 family of processors, now known as mobile platforms. The Snapdragon 660 and 630 Mobile Platforms are important products in the company’s portfolio as they address a larger segment of the consumer market than the premium-tier Snapdragon 800 while still offering performance and feature sets above the budget segments of the 400s. The Snapdragon 820 and 835 traditionally get all of the attention from media, the 600-series is at the heart of popular devices like the Sony Xperia X, Asus Zenfone 3 Ultra, HTC 10 Lifestyle and over 1000 more designs.
The biggest changes to both new platforms come in the form of LTE connectivity and GPU performance. In a bid to bring previously unseen capabilities to the 600-series of solutions, Qualcomm has taken the Snapdragon X12 LTE modem that shipped with the Snapdragon 820/821 SoC and integrated it on both the 660 and 630. This creates mainstream mobile platforms that can run Cat 12/13 modems and speeds as high as 600 Mbps downstream (3x carrier aggregation) and 150 Mbps upstream (2x carrier aggregation).
That is a significant move and should result in a massive amount of high speed devices saturating the market (and carriers’ networks) starting later this year. Along with that higher performance comes the same X12 feature set that we saw with Snapdragon 820/821 including adaptive antenna tuning capability (TruSignal) and dynamic signal quality adjustments for power efficiency optimizations.
The GPU performance of both the Snapdragon 660 and 630 get a boost over the previous competitors (653 and 626 respectively) though they do so with different Adreno implementations. The SD 660 uses the Adreno 512 GPU that offers up to 30% better performance compared to the Adreno 510 used on the SD 650 series. While we don’t have details yet on where that advantage comes from (clocks or core improvements), I have a feeling that much of it comes from improved frequencies. The Snapdragon 630 uses the Adreno 508 GPU, compared to the 506 from the SD 626 processor, and also claims to have a 30% performance advantage over the previous generation.

Delidding a Kaby Lake processor such as the i7-7700k does not offer the same overclocking advantages as with previous generations when replacing the TIM gave you more headroom. Instead of being able to push your CPU past 5GHz, popping the lid off of a Kaby Lake reduces operating temperatures and likely extends the life of the processor ... or immediately ends it. If you don't have a 3D printer handy to make your own delidder, then take a peek at this review from TechPowerUp. They try out two delidding tools, one from Aqua Computer and one from Rockit which Morry has used; do be aware that any CPUs killed as a result of reading their review is the responsibility of the one who delidded.
"Intel mainstream CPUs have had a bottleneck in cooling due to poor heat transfer from the CPU die to the integrated heat spreader. Thanks to new de-lidding friendly tools released recently, it is now easier than ever before to handle this yourself and get a cooler running CPU. We examine two such solutions from Rockit Cool and Aqua Computer today, both of which promise fool-proof de-lidding and re-lidding"

EK's Supremacy line of CPU waterblocks are well known for their performance and style. Their latest version in this block line, the Supremacy MX, advances their design in the hopes of getting more optimized performance out of a less costly version of their award winning block series. The base Supremacy MX CPU waterblock is a copper and plexi construction using the same jet-impingement and micro-channel design as that used in their previous block versions. The block comes fully assembled from the factory with a single CPU mounting bracket type (in this case, the Intel version). Note that additional CPU mounting kits are available for purchase. With an MSRP of $54.99, the Supremacy MX waterblock offers a compelling purchase in light of its performance potential.

The block is assembled with hex-head screws going through the copper base plate with rubber grommets ensuring the integrity of the block internals. The top aluminum cover plate is held to the plexi top using short hex-head screws that thread directly into the plexi top plate. The center inlet feeds the micro-channels embedded in the copper base plate through the jet-impingement assembly. The mounting bracket sits in between the top plexi plate and the copper base plate, making any an interesting upgrade if you want to switch out the CPU mount plate to use the block on a different CPU family (like going from Intel to AMD Ryzen for example). The aluminum top plate gives the block a sleek appearance and acts to redirect illumination from the side mounted LEDs (if you choose to use LEDs with the block that is).

According to DigiTimes, Intel is expecting to release several new processors earlier than they had originally planned. That said, there are two issues with this report. The first point, which should be expected, is that it compares internal dates that were never meant to be public. It is not like Intel has changed their advertised roadmap.
The second problem is that it’s somewhat contradicted by Intel’s earlier, public statements.
Their rumor claims that Intel will push up the launch of Basin Falls, which is Skylake-X, Kaby Lake-X, and X299, by about two months (around June). It also claims that Coffee Lake, which was originally scheduled for January 2018, will be released in August 2017. Both of these moves are being attributed to AMD’s new products.
The potential, somewhat, sort-of contradiction comes from a tweet that Intel made back in February. In it, they said that the 8th generation of Core processors are expected for 2H’17. This time frame doesn’t include January, although it only barely includes August, too. If Intel was always planning on launching Coffee Lake for the “back to school” season, then at least that half of DigiTimes’ story would be completely incorrect. On the other hand, if Intel’s tweet was talking about a sampling / paper launch in December, with volume shipment soon to follow, then DigiTimes would be fairly accurate.
We don’t know unless someone at Intel confirms either-or.
As for Skylake-X and Kaby Lake-X, it would be interesting to see them launch at Computex / E3. Previous rumors (also from DigiTimes) that place it in the Gamescom, which is a huge gaming conference in Cologne. Interestingly, this rumor claims that only the four-, six-, eight-, and ten-core models will arrive at the time, with a twelve-core model waiting until the whole line was supposed to launch.
This omission makes me wonder if, in fact, Intel are rushing the launch, but they realize that they cannot get enough good chips to fill out the top-end SKU. In that case, it would make sense to push the smaller and partially-disabled chips out the door, while banking the big chips that can run all twelve cores at a reasonable voltage for some clock rate.
If so, that would, in fact, speak volumes about AMD’s roadmap (and Intel’s opinion of it).

As you have already read through Ryan's review of the Ryzen 1600X and 1500X running on MSI's B350 Tomahawk you know about how the chips measure up to Intel's offerings at the same price point. Life being what it is, there is always a trade between testing everything and publishing results in a timely manner so it is possible that we missed your favourite game, benchmark or test setting which is why roundups such as this exist. For instance over at [H]ard|OCP the tests were performed on an MSI Krait Z270 Gaming motherboard and they also had a chance to review the $169 Ryzen 5 1400.
Drop by to take a look and don't forget there are a whole lot more just below.
"AMD has been on a tear with its new Ryzen 7 CPUs over the past few weeks and now it is time for the Ryzen 5 processor family performance to be explored. We are giving away the AMD Reviewer's Kit with a 1600X and 1500X, instead we bought 1600 and 1400 processors to review here today. All data is retail CPUs, and all overclocked to 4GHz."

The real battle begins
When AMD launched the Ryzen 7 processors last month to a substantial amount of fanfare and pent up excitement, we already knew that the Ryzen 5 launch would be following close behind. While the Ryzen 7 lineup was meant to compete with the Intel Core i7 Kaby Lake and Broadwell-E products, with varying levels of success, the Ryzen 5 parts are priced to go head to head with Intel's Core i5 product line.
AMD already told us the details of the new product line including clock speeds, core counts and pricing, so there is little more to talk about other than the performance and capabilities we found from our testing of the new Ryzen 5 parts. Starting with the Ryzen 5 1600X, with 6 cores, 12 threads and a $249 price point, and going down to the Ryzen 5 1400 with 4 cores, 8 threads and a $169 price point, this is easily AMD's most aggressive move to date. The Ryzen 7 1800X at $499 was meant to choke off purchases of Intel's $1000+ parts; Ryzen 5 is attempting to offer significant value and advantage for users on a budget.
Today we have the Ryzen 5 1600X and Ryzen 5 1500X in our hands. The 1600X is a 6C/12T processor that will have a 50% core count advantage over the Core i5-7600K it is priced against but a 3x advantage in thread count because of Intel's disabling of HyperThreading on Core i5 desktop processors. The Ryzen 5 1500X has the same number of cores as the Core i5-7500 it will be pitted against, but 2x the thread count.
How does this fare for AMD? Will budget consumers finally find a solution from the company that has no caveats?

Perhaps it is best not to ask how this came about, but you can order the Ryzen 5 1600 and 1400 from eBay. The seller has an impressive reputation and as Kyle over at [H]ard|OCP has already ordered and received some, this should be a fairly safe opportunity to take advantage of. The full review has not yet been published but that did not stop them from putting together a quick overclocking video. If you have 20 minutes to spare and an interest in AMD's new processors you should take a look.
"Much to our surprise, AMD Ryzen 5 CPUs started showing up online for sale last week in North America, so we did what any PC hardware review site would do. We went out and bought four of those and started working on seeing just how much overclocking headroom each of these new CPUs have."

AMD Releases Ryzen Balanced Power Plan - Test Results Inside
AMD has published Community Update #3 to their blog. This update details a new Power Plan that should yield improved gaming performance for those who were previously using the Windows default Balanced Power Profile. There has been lots of speculation on reasons for performance differences when gaming in various power modes and even on different Operating Systems. With this new Ryzen Balanced profile also came some info that should help us clear up some of the other misconceptions out there.
After we determined that the Windows 10 Scheduler was not at fault for the Ryzen performance issues we were seeing in some applications, we received some testing feedback from those who had noted performance differences between Windows 7 and Windows 10. While many believed that to be confirmation of scheduler differences between both Operating Systems, the actual cause was down to how Windows 7 and Windows 10 park their cores, as demonstrated by the points AMD sent us earlier today:
- Windows 7 only parks SMT cores, keeping all physical cores awake.
- Windows 10 keeps the first core awake (logical core 0 + 1 on a HT system) and parks the remainder when possible.
- Windows 10 disables core parking by default on Intel CPUs (Speed Shift support).
Since Windows power management (not the scheduler) is not yet Ryzen aware, its default settings result in overly aggressive core parking when driving a Ryzen CPU. Until a lower level change can take place, AMD has released a custom Ryzen Balanced Power Plan that tweaks some of the P-state transition values and a few other settings to help realize the performance gains previously seen by folks shifting to the High Performance mode while keeping idle power consumption much closer to that of the Balanced plan. Here are AMD’s claimed performance gains (vs. Balanced) with their new Ryzen Balanced Power Plan:
AMD provided claimed gains for Ryzen Balanced profile vs. default Windows Balanced profile.
Realize these gains are all going to be nearly identical to any prior comparison showing Balanced vs. High Performance profile deltas, but this profile retains most of the idle power savings accomplished by the Balanced plan. We’ve been doing some testing with the tool and can partially confirm the above results, while adding in some more of our own that were not included in AMD’s data:
The blue highlighted bars denote the overlapping titles tested. A few other titles we tested showed lesser (or no) gains, but that’s not necessarily the fault of this new profile as those same titles saw similar results with a switch to High Performance mode when tested previously.
I did a bit of digging into exactly which power profile parameters are being tweaked and how. Laymen poking around in Windows Power Management will only find this single difference:
However, deconstructing the actual profile data reveals more changes that do not appear in the Windows GUI. Here are the low-level changes we discovered, including the ‘Minimum processor state’ previously noted above:
Note: Units differ varying by parameter in this chart - compare within each set of 3 bars.
As you can see, changes were made to help minimize the parking of Ryzen cores, and to also speed up their waking when required. It may not be a perfect solution as it is another step that the user must perform to get good ‘out of the box’ Ryzen performance, but it does help alleviate the dilemma of running your desktop machine at full tilt 24/7 or having to switch power modes on either end of your gaming sessions. This is a solid stop-gap until native Ryzen support makes its way into Windows, so all of you Ryzen users out there, run over to the AMD Blog and grab/install the Ryzen Balanced Power Plan!
Tweaks for days
It seems like it’s been months since AMD launched Ryzen, its first new processor architecture in about a decade, when in fact we are only four weeks removed. One of the few concerns about the Ryzen processors centered on its performance in some gaming performance results, particularly in common resolutions like 1080p. While I was far from the only person to notice these concerns, our gaming tests clearly showed a gap between the Ryzen 7 1800X and the Intel Core i7-7700K and 6900K processors in Civilization 6, Hitman and Rise of the Tomb Raider.
A graph from our Ryzen launch coverage...
We had been working with AMD for a couple of weeks on the Ryzen launch and fed back our results with questions in the week before launch. On March 2nd, AMD’s CVP of Marketing John Taylor gave us a prepared statement that acknowledged the issue but promised changes come in form for game engine updates. These software updates would need to be implemented by the game developers themselves in order to take advantage of the unique and more complex core designs of the Zen architecture. We had quotes from the developers of Ashes of the Singularity as well as the Total War series to back it up.
And while statements promising change are nice, it really takes some proof to get the often skeptical tech media and tech enthusiasts to believe that change can actually happen. Today AMD is showing its first result.
The result of 400 developer hours of work, the Nitrous Engine powering Ashes of the Singularity received an update today to version 26118 that integrates updates to threading to better balance the performance across Ryzen 7’s 8 cores and 16 threads. I was able to do some early testing on the new revision, as well as with the previous retail shipping version (25624) to see what kind of improvements the patch brings with it.
Stardock / Oxide CEO Brad Wardell had this to say in a press release:
“I’ve always been vocal about taking advantage of every ounce of performance the PC has to offer. That’s why I’m a strong proponent of DirectX 12 and Vulkan® because of the way these APIs allow us to access multiple CPU cores, and that’s why the AMD Ryzen processor has so much potential,” said Stardock and Oxide CEO Brad Wardell. “As good as AMD Ryzen is right now – and it’s remarkably fast – we’ve already seen that we can tweak games like Ashes of the Singularity to take even more advantage of its impressive core count and processing power. AMD Ryzen brings resources to the table that will change what people will come to expect from a PC gaming experience.”
Our testing setup is in line with our previous CPU performance stories.
|Test System Setup|
|CPU||AMD Ryzen 7 1800X
Intel Core i7-6900K
|Motherboard||ASUS Crosshair VI Hero (Ryzen)
ASUS X99-Deluxe II (Broadwell-E)
|Storage||Corsair Force GS 240 SSD|
|Graphics Card||NVIDIA GeForce GTX 1080 8GB|
|Graphics Drivers||NVIDIA 378.49|
|Power Supply||Corsair HX1000|
|Operating System||Windows 10 Pro x64|
I was using the latest BIOS for our ASUS Crosshair VI Hero motherboard (1002) and upgraded to some Geil RGB (!!) memory capable of running at 3200 MHz on this board with a single BIOS setting adjustment. All of my tests were done at 1080p in order to return to the pain point that AMD was dealing with on launch day.
Let’s see the results.
These are substantial performance improvements with the new engine code! At both 2400 MHz and 3200 MHz memory speeds, and at both High and Extreme presets in the game (all running in DX12 for what that’s worth), the gaming performance on the GPU-centric is improved. At the High preset (which is the setting that AMD used in its performance data for the press release), we see a 31% jump in performance when running at the higher memory speed and a 22% improvement with the lower speed memory. Even when running at the more GPU-bottlenecked state of the Extreme preset, that performance improvement for the Ryzen processors with the latest Ashes patch is 17-20%!
It’s also important to note that Intel performance is unaffected – either for the better or worse. Whatever work Oxide did to improve the engine for AMD’s Ryzen processors had NO impact on the Core processors, which is interesting to say the least. The cynic in me would believe there is little chance that any agnostic changes to code would raise Intel’s multi-core performance at least a little bit.
So what exactly is happening to the engine with v26118? I haven’t had a chance to have an in-depth conversation with anyone at AMD or Oxide yet on the subject, but at a high level, I was told that this is what happens when instructions and sequences are analyzed for an architecture specifically. “For basically 5 years”, I was told, Oxide and other developers have dedicated their time to “instruction traces and analysis to maximize Intel performance” which helps to eliminate poor instruction setup. After spending some time with Ryzen and the necessary debug tools (and some AMD engineers), they were able to improve performance on Ryzen without adversely affecting Intel parts.
Core to core latency testing on Ryzen 7 1800X
I am hoping to get more specific detail in the coming days, but it would seem very likely that Oxide was able to properly handle the more complex core to core communication systems on Ryzen and its CCX implementation. We demonstrated early this month how thread to thread communication across core complexes causes substantially latency penalties, and that a developer that intelligently manages threads that have dependencies on the core complex can improve overall performance. I would expect this is at least part of the solution Oxide was able to integrate (and would also explain why Intel parts are unaffected).

- Ryzen 7 1700X - $399 - Amazon.com
- Ryzen 7 1700 - $329 - Amazon.com
What is important now is that AMD takes this momentum with Ashes of the Singularity and actually does something with it. Many of you will recognize Ashes as the flagship title for Mantle when AMD made that move to change the programming habits and models for developers, and though Mantle would eventually become Vulkan and drive DX12 development, it did not foretell an overall shift as it hoped to. Can AMD and its developer relations team continue to make the case that spending time and money (which is what 400 developer hours equates to) to make specific performance enhancements for Ryzen processors is in the best interest of everyone? We’ll soon find out.
