FREMONT, California — August 14, 2014 — Corsair, a leader in high-performance PC hardware, today announced the availability of Corsair Vengeance LPX and Dominator Platinum lines of high-speed DDR4 computer memory. This new generation of memory ushers in a new age of ultrafast computing with optimizations such as increased DRAM bandwidth, higher bus frequencies, lower power usage, and higher reliability.
Corsair Vengeance LPX and Dominator Platinum DDR4 memory kits are validated with motherboard partners (ASUS, ASRock, EVGA, Gigabyte, and MSI) and use the new XMP 2.0 profile to deliver easy, reliable overclocking performance with the upcoming next-generation Intel® X99 platforms and Intel® Core™ i7 processors (codenamed Haswell-E). The Vengeance LPX and Dominator Platinum memory kits are supplied with a limited lifetime warranty.
Vengeance LPX memory is a new Corsair memory line designed for high-performance overclocking with a low-profile heatspreader is made of pure aluminum for faster heat dissipation and the eight-layer PCB helps manage heat and provides superior overclocking headroom. The memory kits are available in black, red, white, or blue so that enthusiasts, gamers, and modders can add a touch style to match the color scheme of their PC.
Like the DDR3 memory versions, the new Dominator Platinum DDR4 memory kits have a striking industrial design for good looks, patented DHX technology for cooler operation, user-swappable colored “light pipes” for customizable downwash lighting, and Corsair Link compatibility for real-time temperature monitoring. Dominator Platinum memory is built with hand-screened ICs, undergoes rigorous performance testing, and incorporates state-of-the-art cooling for reliable performance in demanding environments.
Vengeance LPX and Dominator Platinum DDR4 Specifications
- Unbuffered DDR4 SDRAM in 288-pin DIMM
- Capacities at launch: 8GB (2x4GB), 16GB (4x4GB), 32GB (4x8GB) and 64GB (8x8GB)
- Speeds at launch: 2666MHz, 2800MHz, and 3000MHz
- Intel XMP 2.0 (Extreme Memory Profile) support
DDR4 is faster. Even at the baseline speed of DDR4 delivers twice the bandwidth with 2133 MT/s (million transfers per second) compared with the base DDR3 1600 MT/s. With optimizations games and applications have the potential to load faster and run more smoothly.
DDR4 uses a lot less power and runs cooler.
With each new generation of CPU and GPU architecture, system power consumption and heat generation become more and more important. DDR4 modules operate at an ultra-low standard 1.2 volts compared to the 1.5 and 1.65 volts of DDR3 memory, allowing DDR4 memory to consume significantly less power and generate less heat.
DDR4 memory modules can get bigger.
DDR3 is limited to 8GB modules for a maximum of 32GB on standard four-socket motherboards. DDR4 will have the ability to enable 16GB per module by 2015. A motherboard with eight memory slots will be upgradeable to an amazing 128GB or DDR4 memory.
Pricing, Availability, and Warranty
Corsair Vengeance LPX Series and Dominator Platinum DDR4 memory kits will be available at the end of August from Corsair's worldwide network of authorized distributors and resellers. The Vengeance LPX and Dominator Platinum memory kits are supplied with a limited lifetime warranty and are backed up by Corsair's customer service and technical support.

ASUS recently launched the RT-AC87U which is the first "wave 2" 802.11ac wireless router to support multi user MIMO (MU-MIMO) technology. Although the initial launch happened at the end of last month, the RT-AC87U and RT-AC87R (a variant exclusive to Best Buy) will finally be avaiable for purchase starting August 26th for around $279.99.
The RT-AC87U is a monster matte black router with four large external antennas and sleek fighter jet angles. I/O is mostly clustered on the rear of the router and includes four Gigabit Ethernet LAN ports, one GbE WAN port, and one USB 2.0 port. In addition to the rear I/O, ASUS has positioned a USB 3.0 port on the front of the router (specifically the right corner of the front panel hidden behind a removeable rubber port cover).
On the wireless front, the RT-AC87U and RT-AC87R supports the latest 802.11ac and newer 256QAM (600Mbps) 802.11n specification as well as legacy 802.11g/b/a Wi-Fi networks. The router supports simultaneous dual band operation, which results in maximum throughput of 1.73 Gbps on the 5GHz 802.11ac band (4 x 433 Mbps streams) and 600 Mbps on the 2.4GHz 802.11n band.
The new and interesting bit about the RT-AC87 is the MU-MIMO support. MU-MIMO, which stands for Multi-User Multple Input Multiple Output, is the evolution of MIMO technology which debuted with wireless N routers. The ASUS router is able to use multiple anntennas to communicate with a client device to increase bandwidth. Beamforming is used to focus the signal in the direction of the client to get better range and a stronger signal for that specific client. MU-MIMO builds on this technology by allowing the router to track, beamform, and employ multiple transmit and recieve antennas to talk to multiple clients simultaneously. Previously, routers were limited to communicating with a single client at a time (see the diagram below for an example).
Multi-User MIMO will benefit those users that choose to connect the majority of their networked devices via Wi-Fi. However, the technology will be especially noticeable in areas flooded with various Wi-Fi networks such as apartments. According to Matthew Gast of Aerohive Networks, MU-MIMO will allow all wireless clients to get an acceptable data rate in crowded wireless areas at the expense of being able to deliver the highest data rate to a single client device. Especially when competing Wi-Fi networks are involved and fighting for channels, MU-MIMO will shine at keeping devices connected and talking to the access point.
ASUS has chosen the Quantenna QSR100 chipset to handle the 802.11ac duties while a Broadcom BCM4709 chipset handles the 256QAM wireless N bands. Additionally, the RT-AC87 routers have 128MB of flash memory and 256MB of DDR3 RAM. According to ASUS, the router draws slightly over 45W.
On the software side of things, ASUS has chosen its own ASUSWRT firmware which includes parental controls, Time Machine backup support, VPN support, security software from TrendMicro (AiProtection), and AiCloud 2.0. USB support includes storage sharing as well as 3G/4G cellular modem internet connectivity.
In all, the ASUS RT-AC87U looks to be new home router champion packing quite a bit of hardware and leading the charge of Wave 2 802.11ac wireless routers. This all comes at a cost, however. The RT-AC87U and RT-AC87R will be available on August 26 with a MSRP of $269.99 and e-tail prices currently around $279.99.

Tagged: amd, freesync, g-sync, Siggraph, siggraph 2014
At SIGGRAPH, Richard Huddy of AMD announced the release windows of FreeSync, their adaptive refresh rate technology, to The Tech Report. Compatible monitors will begin sampling "as early as" September. Actual products are expected to ship to consumers in early 2015. Apparently, more than one display vendor is working on support, although names and vendor-specific release windows are unannounced.
As for cost of implementation, Richard Huddy believes that the added cost should be no more than $10-20 USD (to the manufacturer). Of course, the final price to end-users cannot be derived from this - that depends on how quickly the display vendor expects to sell product, profit margins, their willingness to push new technology, competition, and so forth.
If you want to take full advantage of FreeSync, you will need a compatible GPU (look for "gaming" support in AMD's official FreeSync compatibility list). All future AMD GPUs are expected to support the technology.

The Diamond Xtreme Sound XS71HDU could be a versitile $60 solution for those with high end audio equipment that would benefit from a proper DAC. With both optical in and out it is capable of more than an onboard solution, not to mention the six 3.5-mm jacks for stereo headphones, 7.1 surround support with rear, sub, side, mic, and line in. The design and features are impressive however the performance failed to please The Tech Report who felt that there were similar solutions with much higher quality sound reproduction.
"We love sound cards here at TR, but they don't fit in every kind of PC. Diamond's Xtreme Sound XS71HDU serves up the same kinds of features in a tiny USB package suitable for mini-PCs and ultrabooks. We took it for a spin to see if it's as good as it looks."

For many Linux is a mysterious thing that is either dead or about to die because no one uses it. Linux.com has put together an overview of what Linux is and where to find it being used. Much of what they describe in the beginning applies to all operating systems as they share similar features, it is only in the details that they differ. If you have only thought about Linux as that OS that you can't game on then it is worth taking a look through the descriptions of the distributions and why people choose to use Linux. You may never build a box which runs Linux but if you are considering buying a Steambox when they arrive on the market you will find yourself using a type of Linux and having a basic understanding of the parts of the OS for troubleshooting and optimization. If you already use Linux then fire up Steam and take a break.
"For those in the know, you understand that Linux is actually everywhere. It's in your phones, in your cars, in your refrigerators, your Roku devices. It runs most of the Internet, the supercomputers making scientific breakthroughs, and the world's stock exchanges."

Tagged: siggraph 2014, Siggraph, microsoft, Intel, DirectX 12, directx 11, DirectX
Along with GDC Europe and Gamescom, Siggraph 2014 is going on in Vancouver, BC. At it, Intel had a DirectX 12 demo at their booth. This scene, containing 50,000 asteroids, each in its own draw call, was developed on both Direct3D 11 and Direct3D 12 code paths and could apparently be switched while the demo is running. Intel claims to have measured both power as well as frame rate.
Variable power to hit a desired frame rate, DX11 and DX12.
The test system is a Surface Pro 3 with an Intel HD 4400 GPU. Doing a bit of digging, this would make it the i5-based Surface Pro 3. Removing another shovel-load of mystery, this would be the Intel Core i5-4300U with two cores, four threads, 1.9 GHz base clock, up-to 2.9 GHz turbo clock, 3MB of cache, and (of course) based on the Haswell architecture.
While not top-of-the-line, it is also not bottom-of-the-barrel. It is a respectable CPU.
Intel's demo on this processor shows a significant power reduction in the CPU, and even a slight decrease in GPU power, for the same target frame rate. If power was not throttled, Intel's demo goes from 19 FPS all the way up to a playable 33 FPS.
Intel will discuss more during a video interview, tomorrow (Thursday) at 5pm EDT.
Maximum power in DirectX 11 mode.
For my contribution to the story, I would like to address the first comment on the MSDN article. It claims that this is just an "ideal scenario" of a scene that is bottlenecked by draw calls. The thing is: that is the point. Sure, a game developer could optimize the scene to (maybe) instance objects together, and so forth, but that is unnecessary work. Why should programmers, or worse, artists, need to spend so much of their time developing art so that it could be batch together into fewer, bigger commands? Would it not be much easier, and all-around better, if the content could be developed as it most naturally comes together?
That, of course, depends on how much performance improvement we will see from DirectX 12, compared to theoretical max efficiency. If pushing two workloads through a DX12 GPU takes about the same time as pushing one, double-sized workload, then it allows developers to, literally, perform whatever solution is most direct.
Maximum power when switching to DirectX 12 mode.
If, on the other hand, pushing two workloads is 1000x slower than pushing a single, double-sized one, but DirectX 11 was 10,000x slower, then it could be less relevant because developers will still need to do their tricks in those situations. The closer it gets, the fewer occasions that strict optimization is necessary.
If there are any DirectX 11 game developers, artists, and producers out there, we would like to hear from you. How much would a (let's say) 90% reduction in draw call latency (which is around what Mantle claims) give you, in terms of fewer required optimizations? Can you afford to solve problems "the naive way" now? Some of the time? Most of the time? Would it still be worth it to do things like object instancing and fewer, larger materials and shaders? How often?

As far as factory overclocks go, the 1080MHz core and 5.64GHz RAM on the new Sapphire Vapor-X 290X is impressive and takes the prize for the highest factory overclock on this card [H]ard|OCP has seen yet. That didn't stop them from pushing it to 1180MHz and 5.9GHz after a little work which is even more impressive. At both the factory and manual overclocks the card handily beat the reference model and the manually overclocked benchmarks could meet or beat the overclocked MSI GTX 780 Ti GAMING 3G OC card. The speed is not the only good feature, Intelligent Fan Control keeps two of the three fans from spinning when the GPU is under 60C which vastly reduces the noise produced by this card. It is currently selling for $646, lower than the $710 that the GeForce is currently selling for as well.
"We take a look at the SAPPHIRE Vapor-X R9 290X TRI-X OC video card which has the highest factory overclock we've ever encountered on any AMD R9 290X video card. This video card is feature rich and very fast. We'll overclock it to the highest GPU clocks we've seen yet on R9 290X and compare it to the competition."

Before even looking at the performance the real selling point of the new OCZ ARC 100 is the MSRP, the 240GB and 480GB models are slated to be released at $0.50/GB and will likely follow the usual trend of SSD prices and drop from there. The drives use the Barefoot 3 controller, this one clocked slightly lower than the Vertex 460 but still capable of accelerating encryption. Once The Tech Report set the drive up in their test bed the performance was almost on par with the Vertex 460 and other mid to high end SSDs, especially in comparison to the Crucial MX100.
"OCZ's latest value SSD is priced at just $0.50 per gig, but it hangs with mid-range and even high-end drives in real-world and demanding workloads. It's also backed by an upgraded warranty and some impressive internal reliability data provided by OCZ. We take a closer look:"

Tagged: tonga, radeon, FirePro W7100, amd
A little secret popped out with the release of AMD's FirePro W7100, a new family of GPU that goes by the name of Tonga, which is very likely to replace the aging Tahiti chip that has been used since the HD 7900 series. The stats that The Tech Report saw show interesting changes from Tahiti including a reduction of the memory interface to 256-bit which is in line with NVIDIA's current offerings. The number of stream processors might be reduced to 1792 from 2048 but that is based on the W7100 and it the GPUs may be released with the full 32 GCN compute units. Many other features have seen increases, the number of Asynchronous Compute Engines goes from 2 to 8, the number of rasterized triangles per clock doubles to 4 and it adds support for the new TrueAudio DSP and CrossFire XDMA.
"The bottom line is that Tonga joins the Hawaii (Radeon R9 290X) and Bonaire (R7 260X) chips as the only members of AMD' s GCN 1.1 series of graphics processors. Tonga looks to be a mid-sized GPU and is expected to supplant the venerable Tahiti chip used in everything from the original Radeon HD 7970 to the current Radeon R9 280."

While it may not seem like it in North America, we are in a busy week for videogame development. GDC Europe, which stands for Game Developers Conference Europe, is just wrapping up to make room for Gamescom, which will take up the rest of the week. Valve will be there and people are reading tea leaves to find out why. SteamOS seems likely, but what about their next generation gaming engine, Source 2? Maybe it already happened?
Valve is the most secretive company with values of openness that I know. They are pretty good at preventing leaks from escaping their walls. Recently, Dota 2 was updated to receive new features and development tools for user-generated maps and gametypes. The tools currently require 64-bit Windows and a DirectX 11-compatible GPU.
Those don't sound like Source requirements...
And the editor doesn't look like Valve's old tools.

Leaks also point to things like "tf_imported", "left4dead2_source2", and "left4dead2_imported". This is interesting. Valve is pushing Dota 2, their most popular, free-to-play game into Source 2. Also, because it is listed as "tf" rather than "tf2", like "dota" is not registered as "dota2" but "left4dead2" keeps its number, this might mean that the free-to-play Team Fortress 2 could be in a perpetual-development mode, like Dota 2. Eventually, it could be pushed to the new engine and given more content.
As for Left4Dead2? I am wondering if it is intended to be a product, rather than an internal (or external) Source 2 tech demo.
Was this what brought Valve to Gamescom, or will be be surprised by other announcements (or nothing at all)?

Ryan was not the only one to test the ASUS ROG Swift PG278Q G-Sync monitor, Overclockers Club also received a model to test out. Their impressions of the 27" 2560 x 1440 TN panel were very similar, once they saw this monitor in action going back to their 30-inch 60Hz IPS monitor was not as enjoyable as once it was. The only bad thing they could say about the display was the MSRP, $800 is steep for any monitor and makes it rather difficult to even consider getting two or more of them for a multiple display system.
”When you get down to it, the facts are that even with a TN panel being used for the high refresh rate, the ASUS ROG Swift PG278Q G-Sync monitor delivers great picture quality and truly impressive gaming. I could go on all day long about how smooth each of the games played while testing this monitor, but ultimately not be able to show you without having you sit at the desk with me. No stuttering, no tearing, no lag; it's like getting that new car and having all the sales hype end up being right on the money. When I flip back and forth between my 60Hz monitor and the PC278Q, its like a night and day experience.”

Currently available for a mere $870 the 8GB DDR3-3100 dual channel kit from ADATA with timings of 12-14-14-36 has to be among the most expensive consumer RAM available on the market. We can only hope that DDR4 does not arrive at a similar speed and price point but instead with slower clocked DIMMs at a more reasonable price and with improvements to performance. Legit Reviews' testing showed that these DIMMs offer almost no benefit over DDR3-1600 with tighter timings in real usage but you can get higher scores on synthetic benchmarks. If benchmarking better than the competition and swap-able heatspreaders with different colours is attractive to you then you could pick up these DIMMs, otherwise you really won't be getting value for your money.
"Gone are the days of being on the cutting edge of memory with DDR3 running at 2133MHz! These days running 2133MHz memory is pretty much considered the norm for a high end gaming rig. If you’re looking to be on the bleeding edge of memory speeds you’re going to be limited to only one or two kits. Today we have one of the fastest kits available on the market to put through the paces, the ADATA XPG V3 DDR3 3100MHz 8GB memory kit. Read on to see if this big dollar kit is worth nearly a thousand dollars."

Transactional Synchronization Extensions, aka TSX, are a backwards compatible set of instructions which first appeared in some Haswell chips as a method to improve concurrency and multi-threadedness with as little work for the programmer as possible. It was intended to improve the scaling of multi-threaded apps running on multi-core processors and has not yet been widely adopted. The adoption has run into another hurdle, in some cases the use of TSX can cause critical software failures and as a result Intel will be disabling the instruction set via new BIOS/UEFI updates which will be pushed out soon. If your software uses the new instruction set and you wish it to continue to do so you should avoid updating your motherboard BIOS/UEFI and ask your users to do the same. You can read more about this bug/errata and other famous problems over at The Tech Report.
"The TSX instructions built into Intel's Haswell CPU cores haven't become widely used by everyday software just yet, but they promise to make certain types of multithreaded applications run much faster than they can today. Some of the savviest software developers are likely building TSX-enabled software right about now."

NVIDIA Reveals 64-bit Denver CPU Core Details, Headed to New Tegra K1 Powered Devices Later This Year

During GTC 2014 NVIDIA launched the Tegra K1, a new mobile SoC that contains a powerful Kepler-based GPU. Initial processors (and the resultant design wins such as the Acer Chromebook 13 and Xiaomi Mi Pad) utilized four ARM Cortex-A15 cores for the CPU side of things, but later this year NVIDIA is deploying a variant of the Tegra K1 SoC that switches out the four A15 cores for two custom (NVIDIA developed) Denver CPU cores.
The custom 64-bit Denver CPU cores use a 7-way superscalar design and run a custom instruction set. Denver is a wide but in-order architecture that allows up to seven operations per clock cycle. NVIDIA is using a custom ISA and on-the-fly binary translation to convert ARMv8 instructions to microcode before execution. A software layer and 128MB cache enhance the Dynamic Code Optimization technology by allowing the processor to examine and optimize the ARM code, convert it to the custom instruction set, and further cache the converted microcode of frequently used applications in a cache (which can be bypassed for infrequently processed code). Using the wider execution engine and Dynamic Code Optimization (which is transparent to ARM developers and does not require updated applications), NVIDIA touts the dual Denver core Tegra K1 as being at least as powerful as the quad and octo-core packing competition.
Further, NVIDIA has claimed at at peak throughput (and in specific situations where application code and DCO can take full advantage of the 7-way execution engine) the Denver-based mobile SoC handily outpaces Intel’s Bay Trail, Apple’s A7 Cyclone, and Qualcomm’s Krait 400 CPU cores. In the results of a synthetic benchmark test provided to The Tech Report, the Denver cores were even challenging Intel’s Haswell-based Celeron 2955U processor. Keeping in mind that these are NVIDIA-provided numbers and likely the best results one can expect, Denver is still quite a bit more capable than existing cores. (Note that the Haswell chips would likely pull much farther ahead when presented with applications that cannot be easily executed in-order with limited instruction parallelism).
NVIDIA is ratcheting up mobile CPU performance with its Denver cores, but it is also aiming for an efficient chip and has implemented several power saving tweaks. Beyond the decision to go with an in-order execution engine (with DCO hopefully mostly making up for that), the beefy Denver cores reportedly feature low latency power state transitions (e.g. between active and idle states), power gating, dynamic voltage, and dynamic clock scaling. The company claims that “Denver's performance will rival some mainstream PC-class CPUs at significantly reduced power consumption.” In real terms this should mean that the two Denver cores in place of the quad core A15 design in the Tegra K1 should not result in significantly lower battery life. The two K1 variants are said to be pin compatible such that OEMs and developers can easily bring upgraded models to market with the faster Denver cores.
For those curious, In the Tegra K1, the two Denver cores (clocked at up to 2.5GHz) share a 16-way L2 cache and each have 128KB instruction and 64KB data L1 caches to themselves. The 128MB Dynamic Code Optimization cache is held in system memory.
Denver is the first (custom) 64-bit ARM processor for Android (with Apple’s A7 being the first 64-bit smartphone chip), and NVIDIA is working on supporting the next generation Android OS known as Android L.
The dual Denver core Tegra K1 is coming later this year and I am excited to see how it performs. The current K1 chip already has a powerful fully CUDA compliant Kepler-based GPU which has enabled awesome projects such as computer vision and even prototype self-driving cars. With the new Kepler GPU and Denver CPU pairing, I’m looking forward to seeing how NVIDIA’s latest chip is put to work and the kinds of devices it enables.
Are you excited for the new Tegra K1 SoC with NVIDIA’s first fully custom cores?

Several rowboats worth of snacks, a couple of canoe-fulls of assorted beverages and boatloads of fun were had this weekend in the highly successful 7th Fragging Frogs VLAN; if you missed it there will be another chance some day but you really missed an epic event. There were over 120 Teamspeak connections in a variety of channels and an estimated peak of 78 active participants. Thanks to AMD there is a new game for the Frogs as well as Plants vs. Zombies Garden Warfare was a hit both to the players and to those watching iamApropos' live stream. We also gained some ARMA 2 fans which will not only appear again next VLAN but is also in danger of becoming a frequent activity for some members.
Once again there was quite a bit of valuable hardware and software given away, the list includes:
- AMD Fan Kit (headset, 16 GB USB drive, mouse)
- AMD Gaming Series RAM - 8 GB of 2133 Mhz
- MSI Military Class 4 A88XM-E35 FM2+ motherboard *and* A10-7850K APU
- AMD FX-8350 Processor
- XFX R9 290 Double D graphics card
- Several Plants vs Zombies: Garden Warfare Origin codes
AMD Red Team+
- Murdered Soul Suspect game codes
- Sniper Elite 3 game codes
Please stop by this thread to offer your thanks and support for all the hard work put into these events by Lenny, iamApropos, Spazster, Brandito, Cannonaire, AMD and the Frogs in general.
