Anandtech: The AMD Radeon RX 580 & RX 570 Review: A Second Path to Polaris
Launching today is AMD’s new Radeon RX 500 series. As we’re covering in our companion launch article, the RX 500 series is a refresh of Polaris, bringing about newer, faster SKUs based on the existing Polaris 10 and 11 GPUs. Also joining the family is a newer, smaller GPU, Polaris 12, which will be the basis of the Radeon RX 550. AMD is using an updated revision of Polaris for all of these products, so there are some minor clockspeed improvements and a new memory state that have been baked into the RX 500 family that is not present in the RX 400 family, which makes the new RX 500 parts a bit more interesting.
The first Radeon RX 500 cards out of the gate are the Radeon RX 580 and the Radeon 570, which we’re reviewing today. These SKUs are pretty straightforward: take the new Polaris 10 GPU revision, plug it into more powerful boards, turn up the clockspeeds a bit, and you have a new SKU. AMD hasn’t done anything wild here – the configurations haven’t changed, and in fact TBPs have gone up – so relative to the RX 480 and RX 470, at the end of the day it’s a set of slightly more powerful cards for the same price as before.

Anandtech: Xiaomi Announces Mi 6: 5.15-inch, Snapdragon 835 SoC, 6GB LPDDR4x
Mi 5s it’s replacing, the Mi 6 comes with a 5.15-inch 1080p IPS LCD display and benefits from Xiaomi’s attention to design. The Mi 6 will be sold exclusively in China initially, but will find its way to select global markets at a later date.
Style is just as important to Xiaomi as performance, so it’s no surprise it spent most of the event talking about the Mi 6’s updated design and materials. This generation moves back to edge-to-edge glass on the front and back like the older Mi 5, but the frame is now stainless steel rather than aluminum, which should give it a solid, rigid feel. The sides of the glass back are curved like previous models, but Xiaomi has taken the next step with the Mi 6 by curving the top and bottom edges to match. The curved edges flow smoothly into the polished, rounded metal frame, giving the phone a smooth in-hand feel. The Mi 6 does not use a curved display, but the 2.5D front glass compliments the rounded sides and back.
The Mi 6’s 5.15-inch 1080p IPS LCD panel reaches a peak brightness of 600 nits, the same as the Mi 5s, according to Xiaomi. It’s not clear, however, if the Mi 6 is also using 16 LEDs in the backlight assembly like the Mi 5s to boost brightness and improve power efficiency, or if it’s using 12 to 14 LEDs like most edge-lit IPS displays of this size. With 4096 brightness levels, instead of the usual 256, display brightness can be adjusted more accurately all the way down to just 1 nit. The extended color gamut panel will show vivid, saturated colors, but Xiaomi generally includes an sRGB mode for people who prefer more accurate colors too.

The Mi 6 is one of the first phones to use LPDDR4x RAM, which saves power by using a lower operating voltage than the more common LPDDR4. It pairs the Snapdragon 835 with 6GB of RAM and either 64GB or 128GB of UFS NAND, although there’s no microSD support for supplementing internal storage.
The primary rear camera supports PDAF for faster autofocus performance and comes with the 4-axis OIS system previously seen on the Mi 5, which should improve low-light image quality. An f/1.8 lens, which allows more light to enter the camera, and larger-than-average pixels should also help improve image quality. The secondary camera’s “zoom” lens is slower at f/2.6—a byproduct of its longer focal length—and does not appear to have OIS, which may limit its usefulness in lower-light conditions.

Anandtech: The Intel Optane SSD DC P4800X (375GB) Review: Testing 3D XPoint Performan
Intel's new 3D XPoint non-volatile memory technology, which has been on the cards publically for the last couple of years, is finally hitting the market as the storage medium for Intel's new flagship enterprise storage platform. The Intel Optane SSD DC P4800X is a PCIe SSD using the standard NVMe protocol, but the use of 3D XPoint memory instead of NAND flash memory allows it to deliver great throughput and much lower access latency than any other NVMe SSD. In this review, we go deep to see if it really works as it should.

Anandtech: Dell Announces UP2718Q HDR Display, And Two InfinityEdge Displays
Dell has been in the UHD display game for some time, and the UltraSharp U2715Q and U2415Q have been solid displays for the company for some time, but the latest model takes Dell to a new level. The UP2718Q offers a very wide color gamut, supporting up to 76.9% of the Rec 2020, and each display comes factory calibrated, and it has an adjustable internal lookup-table as well, so it should be able to be tuned accurately if necessary.
HDR, or High Dynamic Range, requires much brighter backlighting than is typical in a desktop display, and the UP2718Q is stated to hit up to 1000 nits, which is likely helped by full-array backlighting.
This display is targeted directly at professionals, and it has a price tag to go along with that, with availability scheduled for May 23 at $1999.99.
ASUS and LG both announcing UHD HRD displays recently as well, but Dell has a substantial presence in the enterprise which will likely help them here.

Anandtech: Toshiba Launches N300 HDDs for NAS: Up to 8 TB, Up to 240 MB/s
The Toshiba N300 family of hard drives consists of three models with 4 TB, 6 TB and 8 TB capacities, a SATA 6 Gb/s interface, a 7200 RPM spindle speed and a 128 MB buffer. All three HDDs are based on a high-reliability platform that attaches a spindle to both sides of a drive (to curb system-induced vibration), has rotational vibration (RV) sensors, shock sensors and temperature sensors as well as supporting error recovery features. The new HDDs are designed for 24/7 availability, 1 million hours MTBF and have a 180 TB/year workload rating, which is in line with other hard drives for NAS devices with 8 bays and is considerably higher than the workload rating of typical desktop HDDs.
Toshiba’s N300 HDDs resemble the company’s MN05-series drives introduced in February (which are also designed for enterprise-class NASes) and are likely based on the same PMR platters (perpendicular magnetic recording) with up to 1.33 TB capacity per platter (the 8 TB version features six of such discs). In addition to the same platters, the N300 drives also have the same power consumption as the MN05 HDDs, but offer slightly different performance, according to the specifications.
As for performance, Toshiba claims up to a 240 MB/s sustained data transfer rate as well as a 4.17 ms average latency time for the N300 8 TB model, which is slower compared to the MN05 8 TB. Meanwhile, since the 6 TB and 4 TB N300 HDDs use different platters, their performance is a bit lower (due to the lower areal density).

Toshiba is already shipping its N300 HDDs to partners and the drives are expected to be available in stores this month. Exact prices will depend on the retailer, but keep in mind that although the N300 are aimed at consumers, they are based on advanced platforms and support numerous enterprise-grade features.

Anandtech: First Look: Samsung Galaxy S8
We first saw Samsung’s new 5.8-inch Galaxy S8 and 6.2-inch Galaxy S8+ at its Unpacked event a few weeks ago. During the event, we saw demos of its new virtual assistant, Bixby, and its DeX docking station, which allows the Galaxy S8 to provide a desktop-like experience by connecting to an external monitor and peripherals, but we didn’t have much time with the phones to do much more than take some pictures and try a couple of the new features. After receiving a Galaxy S8 earlier this week, we wanted to give you some feedback about its design and biometric features, as well as, an initial performance and battery life assessment before we dive into our usual in-depth testing.
My biggest complaint about the design is the location of the fingerprint sensor, which I discuss in the video above. It has been relocated to the back next to the camera, making it difficult to reach and use. The new face unlock feature, the second of the S8’s three biometric authentication options, is flawed too. Despite my best efforts, I was not able to get face unlock to work, not even once. The feature, which relies solely on the front-facing camera for identification, also is not very secure, assuming it works at all. It has already been shown that simply holding a picture in front of the camera is enough to fool it into unlocking the phone. The camera really needs to be augmented with an infrared camera to detect a face’s heat signature as a liveness test, or a second, depth-sensing camera to at least detect a face in three dimensions. So far the iris scanner, which I also demo in the video above, has proven to be the easiest and most reliable biometric option.
Inside the redesigned Galaxy S8 and S8+ is either a Qualcomm Snapdragon 835 or Samsung Exynos 8895 SoC. The US and other regions that require CDMA capability will get the Snapdragon 835, while the rest of the world will get Samsung’s SoC. The new 10nm SoCs are paired with 4GB of LPDDR4 RAM and 64GB of UFS 2.1 NAND. The Galaxy S8 comes with a 3000mAh battery, the same size as the Galaxy S7, while the S8+ comes with a 3500mAh battery, slightly less than the S7 edge’s 3600mAh capacity.

The Galaxy S8 does particularly well in the Writing test, outscoring the Mate 9 by 13% and the Galaxy S7 (Snapdragon 820) by 85%. The Writing test, which previous Galaxy phones struggle with, uses a fairly bursty workload, frequently migrating threads between the little and big cores. Perhaps this is an indication that Samsung is utilizing the big cores more aggressively than in the past. The Galaxy S8 is also 9% faster than the Mate 9 in the Web Browsing test and 37% faster than the S7 (S820).
While we’ve only had the Galaxy S8 for a couple of days, our first impression is generally positive. It’s packed with features, TouchWiz is more refined, and it performed well in our first performance and battery life tests. A few issues are already apparent, however. Your face probably will not be smiling if you try to rely on it to unlock the phone, and the fingerprint sensor is located in just about the worst possible place. Samsung’s Bixby assistant also is not yet fully functional; fortunately, you can still use Google Assistant while you’re waiting for Bixby to mature.

Anandtech: EIZO Announces ColorEdge Prominence CG3145: 4096x2160, 98% P3 and HDR10
The EIZO ColorEdge Prominence CG3145 monitor is based on a 10-bit IPS panel that can reproduce 1.07 billion colors and features a 4096×2160 resolution at 60 Hz. The manufacturer says that the display has a 1000 nits typical brightness (as well as a 1,000,000 static contrast ratio). The ColorEdge Prominence CG3145 covers 98% of the DCI-P3, 99% of the Adobe RGB, as well as 80% of the Rec. 2020 color spaces (but these numbers may change as the product is being tuned up now). This comes with a 24-bit 3D LUT (look-up table) for HDR color gradations. As for connectivity, the display will have one DisplayPort capable of DCI-4K with 4:4:4 chroma subsampling at 50/60 Hz, as well as two HDMI 2.0 inputs capable of DCI-4K with 4:2:2 at 50/60 Hz. Since the monitor is aimed primarily at post production video professionals, EIZO has not currently disclosed support of sRGB and also does not disclose specs like response time or power consumption.
The key feature of the ColorEdge Prominence CG3145 display is its ability to properly reproduce both very bright and very dark areas on the scene without artefacts caused by local dimming (used on many IPS-based televisions and on some monitors) or an auto brightness limiter. EIZO does not reveal many details about the IPS panel it uses for the CG3145, but it claims that it has control of backlight intensity in every pixel. The latter means that the company either uses Panasonic’s IPS panels with a special layer of light-modulating cells that enable pixel-by-pixel control of backlight intensity, or a similar technology it has developed in-house.
In both cases, the pixel-by-pixel control of the backlight sets the ColorEdge Prominence CG3145 display apart from the rivals which use IPS panels with local dimming. Another feature that the monitor has is its 24-bit 3D LUT, which has a potential to produce more accurate colors than the 14-bit 3D LUTs supported by other HDR monitors. Speaking of HDR, it is noteworthy that the CG3145 supports both HLG (hybrid log-gamma) and PQ (perceptual quantization) gamma curves. The HLG is suitable for live TV broadcasting as it has a peak luminance of 1000 nits, whereas the PQ supports considerably higher luminance (up to 10,000 nits) and is suitable for recorded content. The combination of these features means that EIZO has positioned the ColorEdge Prominence CG3145 as a reference monitor for HDR content.
EIZO plans to demonstrate the ColorEdge Prominence CG3145 monitor at the NAB Show later this month. Actual sales of the product are going to start sometimes in late 2017 after the manufacturer finalizes all the details and specifications. Given that the display is not going to show up for another six months, EIZO does not talk about its price. EIZO positions the CG3145 as a reference monitor, which are typically priced above professional-grade models.

Anandtech: Lenovo Launches 2-in-1 Flex 11 Chromebook: Quad-Core SoC, 4 GB RAM, from $
Lenovo was not among the first wave Chromebook manufacturers back in 2011, but released its first laptop running Google’s Chrome OS nearly two years later. Since then the company has been gradually expanding its lineup of Chromebooks targeting different audiences. At first, Lenovo only aimed its ThinkPad X131e Chromebook at students in 2013, then it moved on to business users with the ThinkPad Chromebook 13 in mid-2016. Such approach is perfectly logical because students and road warriors use a relatively limited set of applications. With the Flex 11, the company finally releases a Chrome OS-based computer for general consumers, whose needs are very diverse. One of the reasons why Lenovo can target wide audiences with its Chromebooks is because the Chrome OS now supports Android apps and end users can use a wide range of programs they might need. Keep in mind though that there are not a lot of Android applications developed specifically for tablets or 2-in-1s.
Lenovo Flex 11 Chromebook was designed with Android software in mind, it is not surprising that the manufacturer decided to go with the 2-in-1 form-factor and an 11.6” touchscreen display with a 1366×768 resolution. The 360° hinge of the Flex 11 supports four dynamic modes (watch, tent, laptop, and tablet) to better handle different activities. Lenovo claims that the Flex 11 comes in a drop-resistant enclosure made of plastic with an anti-spill keyboard (can handle up to 330 ml of liquid) and “reinforced” ports (whatever that means). The rugged casing made of thick plastic affected dimensions and weight of the Flex 11: it is 21.2 mm thick and weighs 1.35 kilograms, which means that Lenovo traded portability for lower weight, which is logical as the 2-in-1 has a tablet mode (the lower the better).
When it comes to the CPU, the Lenovo Flex 11 is based on an SoC featuring four ARM cores running at 2.1 GHz. The manufacturer does not elaborate which SoC it uses, but since the notebook looks strikingly similar to the N23 Yoga Chromebook quietly launched earlier this year, it is logical to assume that the two computers use the same processor, the MediaTek MT8173C (also found inside the Acer R13). The MT8173 has two ARM Cortex-A72, two ARM Cortex-A53 general-purpose cores, an LPDDR3 memory controller as well as the PowerVR GX6250 (2 clusters) GPU. The chip was originally released in Q1 2015 and today it can be considered as an entry-level solution, something you expect from a sub-$300 computer.
As for other hardware, the Lenovo Flex 11 is equipped with 4 GB of LPDDR3 memory, 32 GB of eMMC storage (it is possible that higher-end model(s) will include more NAND flash), an 802.11ac Wi-Fi module (no word on Bluetooth, but technically the MT8173 supports it) and a 720p webcam. The laptop also features a USB Type-C port for data and charging, a USB 3.0 header, an HDMI output, an SD card reader as well as a TRRS audio connector for headphones and mic.
Lenovo’s Flex 11 Chromebook will hit the shelves later this month and its entry-level configuration will retail for $279. Lenovo did not say when exactly Android apps are coming to the Flex 11, so if you need them, wait till the Chromebook actually gets an appropriate update.
