The Pixel 2 XL launch hasn’t been going so well for Google. Early complaints were about the screen: how it had alleged burn-in problems within the first few days, and how it couldn’t support the sRGB color space. Since then, we’ve even been hearing reports that some phones shipped without the OS even installed. Whoops!
Now here’s a specific complaint: people are saying that the phone is charging slow. This is an easy one to test – run a multimeter in-line with the USB cable see what happens. Google+ user, Nathan K., apparently did, and he found that the Pixel 2 XL maxed out at 10.5W. When the screen is on, this drops to a maximum of 6W, which he claims (and I would have guessed) is likely due to the combined heat of a phone that’s both in-use and charging. Lithium batteries are very sensitive to heat.
He also says that this issue isn’t really a problem in-and-of itself. He just wishes that manufacturers advertised more about how the battery should perform, and maybe even provide the switches for users to override if needed. I could see that being a warranty nightmare, but I’m rarely going to fall on the side against user choice as a general rule, so I think that would be nice.
Overview and CPU Performance
When Intel announced their quad-core mobile 8th Generation Core processors in August, I was immediately interested. As a user who gravitates towards "Ultrabook" form-factor notebooks, it seemed like a no-brainer—gaining two additional CPU cores with no power draw increase.
However, the hardware reviewer in me was skeptical. Could this "Kaby Lake Refresh" CPU provide the headroom to fit two more physical cores on a die while maintaining the same 15W TDP? Would this mean that the processor fans would have to run out of control? What about battery life?
Now that we have our hands on our first two notebooks with the i7-8550U in, it's time to take a more in-depth look at Intel's first mobile offerings of the 8th Generation Core family.
A potential game changer?
I thought we were going to be able to make it through the rest of 2017 without seeing AMD launch another family of products. But I was wrong. And that’s a good thing. Today AMD is launching the not-so-cleverly-named Ryzen Processor with Radeon Vega Graphics product line that will bring the new Zen processor architecture and Vega graphics architecture onto a single die for the ultrathin mobile notebook platforms. This is no minor move for them – just as we discussed with the AMD EPYC processor launch, this is a segment that has been utterly dominated by Intel. After all, Intel created the term Ultrabook to target these designs, and though that brand is gone, the thin and light mindset continues to this day.
The claims AMD makes about its Ryzen mobile APU (combination CPU+GPU accelerated processing unit, to use an older AMD term) are not to be made lightly. Right up front in our discussion I was told this is going to be the “world’s fastest for ultrathin” machines. Considering that AMD had previously been unable to even enter those markets with previous products, both due to some technological and business roadblocks, AMD is taking a risk by painting this launch in such a light. Thanks to its ability combine CPU and GPU technology on a single die though, AMD has some flexibility today that simply did not have access to previously.
From the days that AMD first announced the acquisition of ATI graphics, the company has touted the long-term benefits of owning both a high-performance processor and graphics division. By combining the architectures on a single die, they could become greater than the sum of the parts, leveraging new software directions and the oft-discussed HSA (heterogenous systems architecture) that AMD helped create a foundation for. Though the first rounds of APUs were able to hit modest sales, the truth was that AMD’s advantage over Intel’s on the graphics technology front was often overshadowed by the performance and power efficiency advantages that Intel held on the CPU front.
But with the introduction of the first products based on Zen earlier this year, AMD has finally made good on the promises of catching up to Intel in many of the areas where it matters the most. The new from-the-ground-up design resulted in greater than 50% IPC gains, improved area efficiency compared to Intel’s latest Kaby Lake core design, and enormous gains in power efficiency compared to the previous CPU designs. When looking at the new Ryzen-based APU products with Vega built-in, AMD claims that they tower over the 7th generation APUs with up to 200% more CPU performance, 128% more GPU performance, and 58% lower power consumption. Again, these are bold claims, but it gives AMD confidence that it can now target premium designs and form factors with a solution that will meet consumer demands.
AMD is hoping that the release of the Ryzen 7 2700U and Ryzen 5 2500U can finally help turn the tides in the ultrathin notebook market.
|Core i7-8650U||Core i7-8550U||Core i5-8350U||Core i5-8250U||Ryzen 7 2700U||Ryzen 5 2500U|
|Architecture||Kaby Lake Refresh||Kaby Lake Refresh||Kaby Lake Refresh||Kaby Lake Refresh||Zen+Vega||Zen+Vega|
|Base Clock||1.9 GHz||1.8 GHz||1.7 GHz||1.6 GHz||2.2 GHz||2.0 GHz|
|Max Turbo Clock||4.2 GHz||4.0 GHz||3.8 GHz||3.6 GHz||3.8 GHz||3.6 GHz|
|System Bus||DMI3 - 8.0 GT/s||DMI3 - 8.0 GT/s||DMI2 - 6.4 GT/s||DMI2 - 5.0 GT/s||N/A||N/A|
|Graphics||UHD Graphics 620||UHD Graphics 620||UHD Graphics 620||UHD Graphics 620||Vega (10 CUs)||Vega (8 CUs)|
|Max Graphics Clock||1.15 GHz||1.15 GHz||1.1 GHz||1.1 GHz||1.3 GHz||1.1 GHz|
The Ryzen 7 2700U will run 200 MHz higher on the base and boost clocks for the CPU and 200 MHz higher on the peak GPU core clock. Though both systems have 4-cores and 8-threads, the GPU on the 2700U will have two additional CUs / compute units.

The official ASUS announcement gave us the specification of their new ROG Strix gaming laptops, but to truly get an idea of how they will perform a review is needed. Thankfully Kitguru got their hands on the GTX 1060 powered model of the Scar and tested its performance in FPS games. As it turns out the design of the laptop helps get the most out of that GTX 1060; the fans are loud but very effective at preventing throttling because of high temperatures. It will not compete with a laptop containing a GTX 1080 but it provides a strong showing compared to similar machines. Drop by for a look at the full review and a video which demonstrates the decibel level you can expect at full load.
"ASUS ROG’s Strix Scar laptop is aimed squarely at first person shooter gamers. It boasts GTX 1060 graphics, an i7-7700HQ processor and 16GB of DDR4 – but most impressive is the 120Hz Full-HD display and its 5ms response time."

Tagged: strix scar, strix hero, ROG, lion king, gaming laptop, asus
ASUS have updated their gaming laptop series with three new models, the ROG Strix Hero and ROG Strix Scar. The Hero is a 15.6" laptop designed for MOBA gaming while the two 17.3" Scar models are intended for FPS players.
As you can see in the specifications, there is no difference between the Hero and Scar GL703VM-DB74 model apart from the size and response rate of the screen. There is a GTX 1060 in both, with an i7-7700HQ and 16GB DDR4-2400 and a 120Hz panel, though only the Scar sports a response time fast enough to make you competitive in a FPS. All models will ship with a 256GB NVMe PCIe SSD and a 1TB FireCuda SSHD with 8GB cache, offering a level of storage performance which is pretty much expected from a gaming laptop today.
The Scar GL503VS-DH74 is a different beast, keeping the CPU and memory but replacing the graphics with a GTX 1070 which powers a 17.3" G-SYNC panel. There was also a variant model announced, which is trims the size to 15.6" but increases the maximum refresh rate to 144MHz.

Qualcomm's latest mobile platform is the Snapdragon 636, positioned (at least numerically) between the Snapdragon 630 and 660 introduced earlier this year, and offering a very impressive set of features for mid-range devices - even reaching parity with the Snapdragon 800-series in some respects.
Qualcomm claims CPU performance gains of up to 40% from the Kryo 260 cores in the Snapdragon 636 compared to the ARM Cortex-A53 cores found in the Snapdragon 630, and the switch to Kryo brings the new Snapdragon 636 closer to the specs of the Snapdragon 660 - also an 8-core Kryo 260 design (though the higher-numbered platform does boast slightly higher clocks from its eight CPU cores at 2.2 GHz vs. 1.8 GHz from the 636).
The Snapdragon 636 also features the same X12 LTE modem found in the existing Snapdragon 630/660, which is capable of up to 600 Mbps download speeds (3 x 20 Hz carrier aggregation, 256-QAM) and 150 Mbps peak upload (2 x 20 Hz aggregation, 64-QAM).
Graphics duties are performed by the Adreno 509, and 18:9 FHD+ displays are supported. The Snapdragon 636 also includes the Hexagon 680 DSP (which we first saw in the Snapdragon 820) with Spectra 160 ISP for supported image capture "of up to 24 megapixels with zero shutter lag while supporting smooth zoom, fast autofocus and true-to-life colors for outstanding image quality", according to Qualcomm.
This new Snapdragon 636 also offers Qualcomm's Aqstic codec (another feature inherited from the 800-series) for high-resolution audio up to 24-bit/192 kHz PCM, along with dual-oscillator support (separate clock generators for 44.1 kHz and 48 kHz based sample rates!) and a 130dB dynamic range with a very low THD+N of -109dB.
To expand on what the Aqstic codec in the SD636 provides, the separate clock generators are a fascinating addition in a world where many codecs resample the common 44.1 kHz - pretty much all digital music at or below CD quality - to 48 kHz during playback. Having a proper 44.1 kHz clock means native playback without the interpolation and subsequent filtering required when altering the original signal to an incompatible sample rate.
The Snapdragon 636 - which is both "pin and software-compatible" with existing Snapdragon 660 and 630 mobile platforms, according to Qualcomm - is expected to ship to customers beginning in November.

Tagged: x50, qualcomm, mmWave, 5g nr, 5G
Earlier this year Qualcomm announced that it had made its first connection with the 5G NR (new radio) through its prototype system. This prototype was constructed to help with the build outs with Ericsson and Vodafone to get 5G in trials in the second of half this year. The device was crude, but effective, and took up a lot of space in a 2U rackmount design.
Today Qualcomm steps up its investment and apparent leadership position with the next generation connectivity technology by showcasing a reference smartphone design that implements the X50 5G modem for the first time.
Though far from a retail-ready announcement, this 9mm thin smartphone design proves that the future of 5G is strong and allows Qualcomm to crow about its position in the field. This design makes several key points, according to the connectivity giant:
- It is the first smartphone-style design integration for the X50 modem, announced a year ago at the company’s 4G/5G summit in Hong Kong.
- Showcases greater than 1Gbps data connectivity on the 100 MHz bands with only a 2xCA (carrier aggregation) implementation.
- Proves the feasibility of mmWave (millimeter wave) technology at 28 GHz in a smartphone with a silicon-based chip that fits four mmWave antenna and a 5G transceiver.
The real bright spot on this design is the inclusion of connectivity support on mmWave technology, previously thought to be extremely difficult to do in a smartphone form factor. Using mmWaves creates complexity due to its reluctance to transmit THROUGH things (including people), so the small surface area of a phone was going to cause issues. By integrating support for four large surface area antenna on this design and the 5G module, Qualcomm believes it has taken a large step in productization.
This reference design will enable trials of 5G technology in real-world environments and use cases. Qualcomm also claims that at launch time (early 2019), the module for the mmWave transceiver will be shrunk by another 50%. Qualcomm hopes that by showing OEMs and carriers that 5G technology challenges are addressable in common and expected form factors, it can accelerate and ease the adoption of the technology for consumers and enterprise applications.

Instead of attaching ye plain olde 1080p fixed refresh rate display to the X5 V7-KL3K3D gaming laptop, Gigabyte chose a 2880x1620 G-SYNC display which is capable of up to a 75Hz refresh rate. As the laptop is powered by a GTX 1070, you will be able to play most games at full resolution, with G-SYNC ensuring a smooth experience. Along with the Kaby Lake i7-7820HK is a Samsung SM961 SSD, so non-graphical tasks also fly. The high end panel does boost the price, the model TechPowerUp reviewed will set you back $2400. If the features are worth it to you, check it out here.
"The AORUS X5 V7-KL3K3D is a stellar offering in terms of specifications, providing impressive performance due to an Intel Quad-Core i7-7820HK CPU, which Gigabyte paired with an NVIDIA GeForce GTX 1070. This relatively thin and light gaming notebook also comes with a 3K IPS display that supports G-Sync."

Huawei has announced the successor(s) to the Mate 9 smartphone with the new Mate 10 and Mate 10 Pro, which feature a new "3D Glass Body" industrial design along with the new Kirin 970 processor and other improvements.
The key features from Huawei include:
- Kirin 970, the world’s first AI processor for smartphones with a dedicated Neural Network Processing Unit (NPU)
- A 3D Glass Body featuring a barely-there-bezel, HUAWEI FullView Display and HDR10 supported technology for intensely vivid and brighter colors
- TÜV Fast-Charge Safety Certified HUAWEI SuperCharge and 4000 mAh battery with AI-powered Battery Management
- New Leica Dual Camera with SUMMILUX-H lenses, with both featuring an aperture of f/1.6, and intelligent photography including AI-powered Real-Time Scene and Object Recognition and AI-powered Bokeh Effect;
- An all-new, simplified EMUI 8.0 based on Android 8.0
The Mate 10 Pro features an 18:9 OLED display
The Mate 10 is a 5.9-inch device with a 16:9 IPS display supporting HDR10, while the Mate 10 Pro offers an 18:9 OLED display (also with HDR10 support).
The new dual-camera system is again a joint effort with Leica, and combines a 12 MP color sensor with a 20 MP monochrome sensor, using lenses with a aperture of f/1.6 - and Huawei says this aperture is the "world's largest" for a smartphone. The digital zoom and bokeh effects are AI-powered, along with real-time scene and object recognition.
The new Kirin 970 combines an 8-core CPU with a 12-core Mali-G72 GPU, and includes an NPU (neural processing unit) for AI-related tasks as well as a new dual ISP for the AI-powered camera features mentioned above.
Both phones include a 4000 mAh battery which offers "smart battery management" which Huawei states "understands user behavior and intelligently allocates resources to maximize battery life". The new TÜV-certified fast charging feature supports low-voltage charging of 4.5V / 5A, and Huawei states this will charge the phones from 1% to 20% in 10 minutes, or 1% to 58% in 30 minutes.
The Mate 10 lineup
The Mate 10 and Mate 10 Pro ship with Android 8.0 and a new "simplified" version of Huawei's EMUI interface. Pricing and availablity for the U.S. was not revealed, but the phones will go on sale internationally starting this month for the Mate 10, and mid-November for the Mate 10 Pro.
The Mate 10 Pro lineup
While we don't have U.S. pricing yet, European pricing for the Mate 10 with 64GB of storage and 4GB memory is set at €699, and the Mate 10 Pro with 128GB/6GB will be €799.
How a ThinkPad is born
During Lenovo's recent ThinkPad 25th Anniversary Event in Yokohama, Japan, we were given an opportunity to learn a lot about the evolution of the ThinkPad brand over the years.
One of the most significant sources of pride mentioned by the Lenovo executives in charge of the ThinkPad division during this event was the team's Yamato Laboratory. Formerly located in Yamato City (hence the name) and relocated to Yokohama in 2011, the Yamato Labs have been responsible for every ThinkPad product, dating back to the IBM days and the original ThinkPad 700C.
This continuity from the earliest days of ThinkPad has helped provide a standard of quality and education passed down from engineer to engineer over the last 25 years of the ThinkPad brand. In fact, some of the original engineers from 1987 are still with the company and working on the latest and greatest ThinkPad innovations. It's impressive to see such continuity and pride in the Japanese development team considering Lenovo's acquisition of the brand back in 2005.
One of the most exciting things was a peek at some of the tests that every device bearing the ThinkPad name must go through, including non-notebook devices like the X1 Tablet.
