As it turns out, there's not much benefit going beyond 8 GB for regular programs, and surprisingly, 4GB still seems to be enough for gaming in most cases. Although RAM is cheap these days, and they had to go to absurdly unrealistic settings to simulate high demand for memory outside of virtualization, it's a good read to confirm our judgment calls on what is enough for most in 2015.

MojoKid writes: Intel's Skylake is here and the new architecture comprises Intel's 6th generation Core line of CPUs. In recent testing it was confirmed that Intel's Skylake-based Core i7-6700K is the company's fastest quad-core desktop processor to date. However, one thing Intel kept a tight lid on was the underlying technology of the Gen9 Intel HD Graphics engine on board Skylake, that is until now. An overview of the changes Intel made specific to Intel Gen9 graphics, notes the following among other tweaks: Available L3 cache capacity has been increased to 768 Kbytes per slice (512 Kbytes for application data). Sizes of both L3 and LLC request queues have been increased. This improves latency hiding to achieve better effective bandwidth against the architecture peak theoretical. Gen9 EDRAM now acts as a memory-side cache between LLC and DRAM. Also, the EDRAM memory controller has moved into the system agent, adjacent to the display controller, to support power efficient and low latency display refresh. Gen9 has also been designed to enable products with 1, 2, or 3 slices, each with 24 EUs per slice and 8 EUs per subslice. Finally, Gen9 adds new power gating and clock domains for more efficient dynamic power management. This can particularly improve low power media playback modes.

Vigile writes: The future of graphics APIs lies in DirectX 12 and Vulkan, both built to target GPU hardware at a lower level than previously available. The advantages are better performance, better efficiency on all hardware and more control for the developer that is willing to put in the time and effort to understand the hardware in question. Until today we have only heard or seen theoretical "peak" performance claims of DX12 compared to DX11. PC Perspective just posted an article that uses a pre-beta version of Ashes of the Singularity, an upcoming RTS utilizing the Oxide Games Nitrous engine, to evaluate and compare DX12's performance claims and gains against DX11. In the story we find five different processor platforms tested with two different GPUs and two different resolutions. Results are interesting and show that DX12 levels the playing field for AMD, with its R9 390X gaining enough ground in DX12 to overcome a significant performance deficit that exists using DX11 to the GTX 980.

Notable additions to the browser include official Windows 10 support, added protection against unwanted software downloads, and new navigational gestures on Android. Firefox 40 for the desktop is available for download now on Firefox.com, and all existing users should be able to upgrade to it automatically. As always, the Android version is trickling out slowly on Google Play. Changelogs are here: desktop and Android.

Phoronix features today a review of Windows 10 that's a little different from most you might read, because it's specifically from the point of view of an admin who uses both Windows and Linux daily, rather than concentrating only on the UI of Windows qua Windows. Reviewer Eric Griffith finds some annoyances (giant start menu even when edited to contain fewer items, complicated process if you want a truly clean install), but also some good things, like improved responsiveness ("feels much more responsive than even my Gnome and KDE installations under Fedora") and an appropriately straightforward implementation of virtual workspaces. Overall? Windows 10 is largely an evolutionary upgrade over Windows 7 and Windows 8.1, rather than a revolutionary one. Honestly I think the only reason it will be declared as 'so good' is because Windows 8/8.1 were so bad. Sure, Microsoft has made some good changes under the surface-- the animations feel crisper, its relatively light on resources, battery life is good. There is nothing -wrong- with Windows 10 aside from the Privacy Policy. If you're on Windows Vista, or Windows 8/8.1, then sure, upgrade. The system is refreshing to use, it's perfectly fine and definitely an upgrade. If you're on Windows 7 though? I'm not so sure. ... Overall, there's really nothing to see here. It's not terrible, it's not even 'bad, it's just... okay. A quiet little upgrade.

An anonymous reader writes: Like many people reading this site, I have several older phones around as well as my newest, fanciest one; I have a minimal service plan on one of these (my next-to-most-recent), and no service plan (only WI-Fi, as available) on the others. Most of them have some reason or other that I like them, so even without service I've kept them around to act as micro-tablets. Some have a better in-built camera than my current phone, despite being older; some are nice on occasion for being small and pocketable; I like to use one as a GPS in the car without dedicating my phone to that purpose; I can let my young relatives use an older one as a camera, etc. Besides, some people have only one phone at all, and can't reasonably afford a new one -- and that probably means a phone that's not cutting edge. So: in light of the several recent Android vulnerabilities that have come to light, and no reason to think they're the last of these, what's a smart way to use older Android phones? Is CyanoGen Mod any less vulnerable? Should I be worried that old personally identifying information from online transactions is still hanging around somewhere in the phone's recesses? I don't want to toss still-useful hardware, but I know I won't be getting any OS upgrades to 3-year-old phones. How do you use older phones that are not going to get OTA updates to address every security issue?

We've heard a lot lately about the release and reception of Windows 10; however, the Windows family includes more than just the most-seen desktop OS. Mark Wilson writes: Microsoft's Gabe Aul has revealed that the company plans to release a new technical preview of Windows Server 2016 later this month. Responding to questions on Twitter, the company's Corporate Vice President and face of the Windows Insider program also said that Windows 10 RSAT [Remote Server Administration Tools] will be launched in August. Unlike the preview builds of Windows 10, previews of the latest edition of Windows Server have been slower to creep out of Redmond. Sysadmins will be keen to get their hands on the latest builds to see just what direction Microsoft is taking with its server software after the decision to delay the launch. We don't know anything about what the third technical preview of Windows Server 2016 might include, but it is likely to be little more than a collection of bug fixes and tweaks. It's a little late in the game to expect any major changes to be made.

New submitter Nillerz writes: What, in your experience, is generally the best way to distribute patches in a way so customers can download them, considering that the machines are offline? Are there any software packages (open source preferred) that pretty much allow engineers to upload a patch with a description to a web server, and allow customers with credentials that are registered in LDAP to browse and download them quickly? And if not, how do you distribute patches to air-gapped machines?

Vigile writes: The Intel Skylake architecture has been on our radar for quite a long time as Intel's next big step in CPU design. We know at least a handful of details: DDR4 memory support, 14nm process technology, modest IPC gains and impressive GPU improvements. But the details have remained a mystery on how the "tock" of Skylake on the 14nm process technology will differ from Broadwell and Haswell. That changes today with the official release of the "K" SKUs of Skylake — the unlocked, enthusiast class parts for DIY PC builders. PC Perspective has a full review of the Core i7-6700K with benchmarks as well as discrete GPU and gaming testing that shows Skylake is an impressive part. IPC gains on Skylake over Haswell are modest but noticeable, and IGP performance is as much as 50% higher than Devil's Canyon. Based on that discrete GPU testing, all those users still on Nehalem and Sandy Bridge might finally have a reason to upgrade to Skylake. Other reviews available at Anandtech, Hot Hardware, [H]ard|OCP, and TechSpot.

An anonymous reader writes: I really want to upgrade to Windows 10, but have begun seeing stories come out about the new Terms and how they affect your privacy. It looks like the default Windows 10 system puts copies of your data out on the "cloud", gives your passwords out, and targets advertising to you. The main reason I am looking to upgrade is that Bitlocker is not available on Windows 7 Pro, but is on Windows 10 Pro, and Microsoft no longer offers Anytime Upgrades to Windows 7 Ultimate. However, I don't want to give away my privacy for security. The other option is to wait until October to see what the Windows 10 Enterprise version offers, but it may not be available through retail. Are the privacy minded Slashdot readers not going with Windows 10?

For reference, I am referring to these articles. (Not to mention claims that it steals your bandwidth.)

jjslash writes to Techspot's interesting look back at the evolution of Intel CPUs since the original Core 2 Duo E6600 and Core 2 Quad processors were introduced. The test pits the eight-year-old CPUs against their successors in the Nehalem, Sandy Bridge and Haswell families, including today's Celeron and Pentium parts which fare comparably well. A great reference just days before Intel's new Skylake processor debuts.

Lauren Weinstein writes: I had originally been considering accepting Microsoft's offer of a free upgrade from Windows 7 to Windows 10. After all, reports have suggested that it's a much more usable system than Windows 8/8.1 — but of course in keeping with the 'every other MS release of Windows is a dog' history, that's a pretty low bar. However, it appears that MS has significantly botched their deployment of Windows 10. I suppose we shouldn't be surprised, even though hope springs eternal. Since there are so many issues involved, and MS is very aggressively pushing this upgrade, I'm going to run through key points here quickly, and reference other sites' pages that can give you more information right now. But here's my executive summary: You may want to think twice, or three times, or many more times, about whether or not you wish to accept the Windows 10 free upgrade on your existing Windows 7 or 8/8.1 system. Now that we're into the first week of widespread availability for the new version, if you're a Windows user and upgrader, has your experience been good, horrible, or someplace between?

MojoKid writes: The OnePlus 2 was officially unveiled [Monday] evening and it has been announced that the smartphone will start at an competitively low $329, unlocked and contract free. The entry level price nets you a 5.5" 1080p display, a cooler-running 1.8GHz Qualcomm Snapdragon 810 v2.1 SoC paired with 3GB of RAM, 16GB of internal storage, a 13MP rear camera (with OIS, laser focusing and two-tone flash), 5MP selfie camera, and dual nano SIM slots. If you don't mind handing over an extra $60, you'll receive 4GB of RAM to back the processor and 64GB of internal storage. Besides beefing up the internal specs, OnePlus has also paid some attention to the exterior of the device, giving it a nice aluminum frame and a textured backplate. There are a number of optional materials that you can choose from including wood and Kevlar. Reader dkatana links to InformationWeek's coverage, which puts a bit more emphasis on what the phone doesn't come with: NFC. Apparently, people just don't use it as much as anticipated.

An anonymous reader writes: With the upcoming Linux 4.2 kernel will be the premiere of the new "AMDGPU" kernel driver to succeed the "Radeon" DRM kernel driver, which is part of AMD's long talked about new Linux driver architecture for supporting the very latest GPUs and all future GPUs. Unfortunately for AMD customers, there's still much waiting. The new open-source AMDGPU Linux code works for Tonga/Carrizo GPUs but it doesn't yet support the latest R9 Fury "Fiji" GPUs, lacks re-clocking/DPM for Tonga GPUs leading to low performance, and there are stability issues under high-load OpenGL apps/games. There's also the matter that current Linux users need to jump through hoops for now in getting the code into a working state with the latest kernel and forked versions of Mesa, libdrm, new proprietary microcode files, and the new xf86-video-amdgpu user-space driver.

New submitter samtuke writes: AMD processors get rated and reviewed based on performance. It is in our self-interest to make things work really, really fast on AMD hardware. AMD engineers contribute to LibreOffice, for good reason. Think about what happens behind a spreadsheet calculation. There can be a huge amount of math. Writing software to take advantage of a Graphics Processing Unit (GPU) for general purpose computing is non-trivial. We know how to do it. AMD engineers wrote OpenCL kernels, and contributed them to the open source code base. Turning on the OpenCL option to enable GPU Compute resulted in a 500X+ speedup, about ¼ second vs. 2minutes, 21 seconds. Those measurements specifically come from the ground-water use sample from this set of Libre Office spreadsheets.

An anonymous reader writes: For those of us who still remember the Hobson's choice with the 3.21 update of the PS3 firmware, the most recent update to the Nvidia Shield Portable is eerily similar. The update, which is necessary to run recent games and apps that require Android 5.0 APIs, removes some features from the device, and removes the games that were bundled with the device, Sonic 4 Episode II and The Expendables: ReArmed. Nvidia has stressed that it is an optional update, but how many users have been told for months that the update was coming, some of whom may have bought the device after the update was announced, only to find out now they won't receive all the functionality they paid for? How is it still legal for these companies to advertise and sell a whole product but only deliver part of it?

Automobile Magazine, writes reader Eloking, reports that the highest-end of the Tesla line has just gotten a boost upward, thanks to a new "Ludicrous Speed" mode: In combination with a newly optional 90-kWh battery pack, this new mode brings 0-60 mph acceleration down to 2.8 seconds (from a quoted 3.2 seconds for the P85D model). This larger battery pack is offered as an upgrade from the existing 85-kWh model, creating new 90, 90D, and P90D models. It doesn't come cheap, though: this isn't just a firmware update to download. For P90D owners, the upgrade costs $10,000 (including the larger battery); P85Ds can be upgraded for half that price.

MojoKid writes: When AMD launched the liquid-cooled Radeon Fury X, it was obvious the was company willing to commit to new architecture and bleeding edge technologies (Fiji and High-Bandwidth Memory, respectively). However, it fell shy of the mark that enthusiasts hoped it would achieve, unable to quite deliver a definitive victory against NVIDIA's GeForce GTX 980 Ti. However, AMD just launched their Radeon R9 Fury (no "X" and sometimes referred to as "Fury Air"), a graphics card that brings a more compelling value proposition to the table. It's the Fury release that should give AMD a competitive edge against NVIDIA in the $500+ graphics card bracket. AMD's Radeon R9 Fury's basic specs are mostly identical to the liquid-cooled flagship Fury X, except for two important distinctions. There's a 50MHz reduction in GPU clock speed to 1000MHz, and 512 fewer stream processors for a total of 3584, versus what Fury X has on board. Here's the interesting news which the benchmark results demonstrate: In price the Fury veers closer to the NVIDIA GeForce GTX 980, but in performance it sneaks in awfully close to the GTX 980 Ti.

Ars Technica reviews the newest release from Linux MInt -- version 17.2, offered with either the Cinnamon desktop, or the lighter-weight MATE, which feels like what Gnome 2 might feel in an alternate universe where Gnome 3 never happened. Reviewer Scott Gilbertson has mostly good things to say about either variety, and notes a few small drawbacks, too. The nits seem to be minor ones, though they might bite some people more than others: Mint, based on Ubuntu deep down, is almost perfectly compatible with Ubuntu packages, but not every one, and this newest version of Mint ships with the 3.16 kernel of Ubuntu 14.04, which means slightly less advanced hardware support. (Gilbertson notes, though, that going with 3.16 means Mint may be the ideal distro if you want to avoid systemd.) "This release sees the Cinnamon developers focusing on some of what are sometimes call "paper cut" fixes, which just means there's been a lot of attention to the details, particularly the small, but annoying problems. For example, this release adds a new panel applet called "inhibit" which temporarily bans all notifications. It also turns off screen locking and stops any auto dimming you have set up, making it a great tool for when you want to watch a video or play a game." More "paper cut" fixes include improved multi-panel options, graphics-refresh tweaks, a way to restart the Cinnamon desktop without killing the contents of a session, graphics-refresh tweaks, and other speed-ups that make this release "noticeably snappier than its predecessor on the same hardware."
