  • NVIDIA Buys ARM - Creating a Premier Company for the Age of AI

    Published: Monday, September 14, 2020 | By: Dennis

    News of NVIDIA buying companies isn't anything new.  Some of the notable purchases include 3Dfx (for SLI), ULi (for motherboard chipsets), AGEIA (for PhysX) and Mellanox (for Datacenter). 

    We can now add another company to that list. ARM.  ARM is the technology behind mobile hardware that is not only powerful (relatively speaking) but power efficient.  Combine that with the power of the NVIDIA GPU and their AI initiative and you have a good formula for success.

    Today, we announced that we have signed a definitive agreement to purchase Arm. 

    Thirty years ago, a visionary team of computer scientists in Cambridge, U.K., invented a new CPU architecture optimized for energy-efficiency and a licensing business model that enables broad adoption. Engineers designed Arm CPUs into everything from smartphones and PCs to cloud data centers and supercomputers. An astounding 180 billion computers have been built with Arm — 22 billion last year alone. Arm has become the most popular CPU in the world.   

    Simon Segars, its CEO, and the people of Arm have built a great company that has shaped the computer industry and nearly every technology market in the world. 

    We are joining arms with Arm to create the leading computing company for the age of AI. AI is the most powerful technology force of our time. Learning from data, AI supercomputers can write software no human can. Amazingly, AI software can perceive its environment, infer the best plan, and act intelligently. This new form of software will expand computing to every corner of the globe. Someday, trillions of computers running AI will create a new internet — the internet-of-things — thousands of times bigger than today’s internet-of-people.

  • Corsair Gaming, Inc. Launches Initial Public Offering

    Published: Monday, September 14, 2020 | By: Dennis

    Back "in the day" an IPO was a really big deal as it indicated that a company was ready to take things to the next level.  An IPO was also a make or break point for a company, some surged while others lost so much value that they were driven into obscurity.

    There were rumors that Corsair was planning an IPO a few months ago and we have finally got confirmation of that today.  Corsair will be trading under "CRSR" with an initial offer price between $16 and $18 USD.

    Corsair has been a great company to work with and while I cannot say I have worked with them in in over 15 years I do wish them all the best however, I suspect in less than a year they will resend their IPO and move back to being a private company again.

    FREMONT, CA. September 14, 2020—Corsair Gaming, Inc. (“Corsair”), a leading global provider and innovator of high-performance gear for gamers and content creators, announced today that it has commenced an initial public offering of 14,000,000 shares of its common stock, approximately 7,500,000 of which are being offered by Corsair and approximately 6,500,000 of which are being offered by a selling stockholder. In connection with the offering, the underwriters will also have a 30-day option to purchase up to an additional 2,100,000 shares of common stock from the selling stockholder. The initial public offering price is estimated to be between $16.00 and $18.00 per share. Corsair has applied to list its common stock on the Nasdaq Global Market under the ticker symbol “CRSR.” The offering is subject to market conditions, and there can be no assurance as to whether, or when, the offering may be completed or as to the actual size or terms of the offering.

  • NVIDIA GeForce RTX 3080 Unboxing & Preview @ TechPowerUp

    Published: Thursday, September 10, 2020 | By: Dennis

    Well, I guess the NVIDIA documentation didn't say anything about posting photos along with an unboxing article. and, yes before you ask NVIDIA didn't send me a GPU for launch so I’ll be stuck again reporting 2nd hand on the awesome which is RTX 30.

    I should be more upset but, after getting passed over for the awesome GTX 10 series launch I just don’t care much anymore.  For me, the AIC board partner products are a little more interesting.

    Image from TechPowerUp

    We go hands on with the NVIDIA GeForce RTX 3080 Founders Edition, which was announced just a few days ago. This first "Ampere" card comes in an amazing packaging, that further supports the product's ultra-high-end premium look and feel. We also take a closer look at the new 12-pin power connector.

    It would seem that the power connector rumors are true, the new RTX cards come with a 12-pin power connector and the overall design is really really nice.  Being that I'm the type to recommend custom PCBs over reference designs I might make an exception when it comes to the new RTX 30 Series.

  • Antec DF600 Flux @ TechPowerUp

    Published: Thursday, September 10, 2020 | By: Dennis

    I'm not sure where I have seen this case before.  The case I am thinking of is a standard mid-tower with spots for three cooling fans up front, of course with RGB and some sort of protector over the fans to keep out cats, fingers while allowing dust and air to enter.

    The case also appears to have a tempered glass side panel and is available in black...  Humm

    Oh ya, my bad. I just described every flipping case on the market!!

    The Antec DF600 Flux clocks in at just $70, but comes with all the bells and whistles we are used to at the $100 price point. Five fans, a clean window, Velcro strips, plenty of space for cooling and storage, RGB controller, and fan hub—the DF600 Flux looks to be breaking new ground in terms of value for your money.

    When it comes to price, $70USD is pretty good though for the money I might suggest picking something better.

  • Crucial P5 NVMe M.2 SSD Review Round Up

    Published: Thursday, September 10, 2020 | By: Dennis

    It has been awhile since I have posted one of these so, go easy on me.

    In April 2020 Crucial announced a new line of performance SSDs that expanded on the P1 line of NVMe drives.  A total of two drives were announced and I was able to review the Crucial P2 NVMe drive in May, as that was the first one to be released.

    Sadly the drive was "slow" but my particular drive was considerably faster due to the components used.  Seems the P2 was a product designed to handle a variety of different NAND configurations.  I'm not sure if P5 will follow this model but it seems pretty good out of the gate.

  • rucial Ballistix DDR4 2x32GB 3600MHz BL2K32G36C16U4B @ LanOC Reviews

    Published: Thursday, September 10, 2020 | By: Dennis

    Gotta say it is nice to see memory reviews hitting the Internet again.  Quite a few companies including Corsair, GSKill and Kingston are extremely reserved when it comes to sending samples making it difficult to find good information on them.  I suspect this is a factor of margins and the company insistence that memory doesn't need to be reviewed.

    I'd like to offer another option which is the reluctance of Tier 1 review sites flat out refusing to review memory.  This has a trickle down effect for smaller sites since it tends to shrink the marketing budget.  I will be honest in saying that reviewing memory is kinda boring, the articles are not very popular and few people (reviewers included) actually understand that makes memory special. 

    In this review from LanOC we can get a sample of the new Crucial Ballistix 3600Mhz modules featuring a new heatspreader design and a really impressive CAS 16 timing set.

    I’ve had the chance over the years to check out a wide variety of Crucial Ballistix branded memory. Being a part of Micron, they have always been priced well, and as far as memory goes been solid. Styling-wise I loved the old Ballistix designs and there are a few of the modern designs like the Elite and their Tactical Tracer RGB kits that I was able to 3D print and CNC carve custom designs for. But as a whole, their mainstream stuff, while not bad looking has looked dated for a while now. So back at the start of the year, they announced new memory kits with new heatspreaders and I was excited to see what Crucial had going on. It took a while to come in, but I recently finally had the Crucial Ballistix BL2K32G36C16U4B kit come in which is their 2x32GB dual channel kit running at 3600 MHz. The timing couldn’t be much better given my personal PC has been begging for more memory with Microsoft Flight Sim 2020 and chrome having full-on MMA fights for the memory. So today I’m going to check out the new design and see how this kit performs.  

    Call me crazy but, I'm not a fan of the new heatspreader design.  I got to see it in person during CES and it simply doesn't seem to have enough style to set it apart in the market.  But, Crucial seems to like it and will likely change the design again in a couple years.  If they are looking to reclaim the top spot in the retail memory market they are going to have to settle down.

    Micron GDDR6X accelerates photorealistic 3D experiences at 1 terabyte per second, rates once thought impossible

    BOISE, Idaho, Sept. 01, 2020 (GLOBE NEWSWIRE) -- Micron Technology, Inc. (Nasdaq: MU), today announced the world’s fastest discrete graphics memory solution, GDDR6X, the first to power system bandwidth up to 1 terabyte per second (TB/s). Working with visual computing technology leader NVIDIA, Micron debuted GDDR6X in the new NVIDIA® GeForce RTX™ 3090 and GeForce RTX 3080 graphics processing units (GPUs), which are tailored to support the fast speeds that immersive, high-performance gaming applications demand.

    “Our multilevel signaling innovation in GDDR6X has shattered conventional bandwidth limits, clocking record-breaking speeds,” said Tom Eby, senior vice president and general manager of the Compute & Networking Business Unit at Micron. “Unlike traditional memory, GDDR6X has unparalleled data rates that can keep pace with gaming innovation and data-hungry applications — setting a new standard for graphics memory.”

    Micron’s GDDR6X serves as a powerful enabler of NVIDIA GeForce RTX 3090 and GeForce RTX 3080 graphics cards’ performance. Building on its most recent collaboration with NVIDIA for the GeForce RTX graphics card (enabled by GDDR6), Micron transforms the memory/GPU interface with GDDR6X, accelerating performance on complex graphics workloads across next-generation gaming applications.

    “With the unprecedented speed of GDDR6X, Micron has delivered tomorrow’s memory technology today, and it’s at the heart of NVIDIA GeForce RTX 3090 and 3080 GPUs — helping us deliver rich, realistic, cinematic user experiences,” said Jeff Fisher, senior vice president of the GPU Business Unit at NVIDIA. “Building on a history of collaboration that started with GDDR5, we’re thrilled to have reinvented the memory/GPU interface with Micron, setting a new bar for high-performance, high-resolution gaming.”

    As PC gaming evolves in sophistication, gamers today demand the highest performance for their advanced graphics cards — a requisite for smooth animation, sharp visuals, 8K resolution and real-time ray tracing, a rendering technique that results in realistic light reflections and cinematic effects. GDDR6X’s groundbreaking speed offers discerning gamers high-resolution experiences with maximum frame rates and instant rendering, allowing users to experience highly realistic and reactive effects without jarring lags. Combined with NVIDIA’s GeForce RTX 3090 and GeForce RTX 3080 GPUs, GDDR6X’s ultra-bandwidth capabilities improve real-time ray tracing and neural graphics processing to create photorealistic and immersive virtual worlds in PC games.

    The new NVIDIA GeForce RTX 30 Series GPUs — the second generation of the NVIDIA RTX PC gaming platform — feature new ray tracing cores, Tensor Cores and streaming multiprocessors.

    Beyond the Binary: First to Implement PAM4 in Memory, Micron Sets New Benchmark

    Micron achieved GDDR6X’s breakthrough bandwidth by applying innovative signal transmission technology, four-level pulse amplitude modulation (PAM4), to revolutionize how memory moves data. Since 2006, Micron’s engineers and researchers have explored applying multilevel signaling to the memory interface. Over 45 patents later, Micron is the first in the industry to implement PAM4 in memory, creating a new benchmark for future generations of graphics memory.

    By using PAM4 multilevel signaling techniques, GDDR6X transfers data much faster, doubling the input/output (I/O) data rate. Until now, graphics memory was capped at 64 gigabytes per second (GB/s), transmitting one bit per cycle through the traditional binary standard, which relies on two signal levels to transmit data encoded as 1s or 0s. Instead, Micron’s novel PAM4 technique employs four distinct levels to transmit two bits of data to and from the memory at a time. As a result, Micron’s GDDR6X dramatically increases memory bandwidth to 84 GB/s for each component, translating to system bandwidth of up to 1 TB/s — rates once thought impossible.

    Micron’s GDDR6X is also the only memory device using PAM4 that can be designed and built in mass production volumes, bringing cutting-edge I/O research to market. With its board design and packaging carefully fine-tuned for simplicity by Micron’s graphics memory experts, GDDR6X offers customers easy implementation and less manufacturing complexity than other high-bandwidth solutions on the market. Notably, GDDR6X doubles the data rate in a channel without doubling the required operating frequency, creating a smooth, real-time experience for gamers.

    In addition, GDDR6X delivers lower power per transaction (pJ/bit) than previous generations, making it ideal for energy-sapping workloads like gaming and other high-bandwidth graphics applications, which demand both lightning fast and low-power memory. GDDR6X also features the ability to scale power down or up, allowing users to dial back performance to save energy.

    The GeForce RTX 3080 is available for purchase starting Sept. 17, and the GeForce RTX 3090 is available starting Sept. 24 on NVIDIA’s website. Both will be available as custom boards, including stock-clocked and factory-overclocked models from top add-in card providers and in gaming systems from leading OEMs and system builders.

    GDDR6X is now available as part of Micron’s new Ultra-Bandwidth Solutions portfolio. Micron delivers GDDR6X memory in 8 gigabits (Gb) density, with speeds of 19 to 21 Gb/s. Starting in 2021, 16Gb density units will be added. Partners and customers interested in exploring GDDR6X for their high-performance solutions — whether for gaming, artificial intelligence inference or professional visualization — can find out more here.
