    Anandtech: Samsung Unveils 6th Generation V-NAND Memory with Up to 136 Layers

    Samsung on Tuesday introduced its sixth-generation V-NAND memory with over 100 active layers. To make V-NAND with over 100 layers viable from performance point of view, the company had to use new circuit design technology. The new memory features 10% lower latencies and consumes 15% lower amount of power when compared to previous-generation V-NAND.
    Samsung’s 6th Generation V-NAND features up to 136 layers as well as charge trap flash (CTF) cells. The new memory uses one stack and does not use technologies like string stacking to build over 100 layers. In order to ensure lack of errors and low latencies, Samsung had to use a new speed-optimized circuit design. The latter enabled the new 3D TLC 256 Gb chips to offer below 450 microseconds (μs) latency for write operations and below 45 μs for read operations, which is 10% faster when compared to 5th Generation V-NAND, according to Samsung. Meanwhile, the latest V-NAND also features lower power consumption than its predecessors.
    It is noteworthy that the new 256 Gb 136-layer V-NAND devices use 670 million holes, down from 930 million holes with the previous generation, which means that the new chips need less process steps and are easier to manufacture. What is important is that Samsung plans to use its 136-layer architecture with speed-optimized circuit design to build V-NAND devices with over 300 layers by mounting three of the current stacks on top of each other (thus tripling a chip’s capacity).
    Initially, Samsung will offer 256 Gb 3D TLC 136-layer V-NAND devices that will first be used for Samsung’s 250 GB SSDs. Later this year Samsung intends to release 512 Gb 136-layer V-NAND devices that will be used for other drives as well as eUFS storage solutions.
    Speaking of the 256 GB 6th Gen V-NAND SSD, it is important to point out that it uses Samsung’s new controller marked as the S4LR030/S94G4MW2.

    Anandtech: Samsung Announces the Exynos 9825 SoC: First 7nm EUV Silicon Chip

    This year’s Galaxy S10 has been in a bit of an odd situation: Although Samsung continued to dual-source its SoCs, using both its own Exynos 9820 SoC as well as Qualcomm’s Snapdragon 855, the phone found itself in the unusual situation of pitting 8nm silicon against 7nm silicon from TSMC. So although the new Exynos 9820 did fairly well in testing and improved a lot over the Exynos 9810, the chip seemingly still had disadvantages against the competition when it came to power efficiency, likely linked to its process technology disadvantages. On top of the power efficiency disadvantages, the chip also had a notable die area disadvantage versus the Snapdragon, coming in at 127mm² versus the smaller 73mm² competition.
    Samsung’s 7nm EUV process node was noted as having started mass production back in October of last year, although we’re not sure exactly which chip this was referring to, and we had hopes that it would be the chip for the S10 but alas it was not to be.
    This time around, Samsung is seemingly bridging the gap with the introduction of the new Exynos 9825 – a 7nm LPP refresh of the Exynos 9820.

    The new chip very much looks like a die-shrink/mid-cycle refresh with largely the same IP generation as the 9820, still featuring Samsung’s M4 Cheetah cores as well as a Mali-G76 GPU. Samsung also doesn’t seem to have changed the clock frequencies of the chip very much: The M4 cores are still running at a peak frequency of 2.73GHz and the A55 cores also run at 1.95GHz. We do see a bump in the frequencies of the middle cores that goes up from 2.31GHz to 2.4GHz.
    On the GPU side, Samsung has also stuck with the same GPU configuration as with 9820, using a MP12 configuration of the G76. According to the company the 9825's GPU is clocked hgiher - so it will outperform its predecessor - however the company has yet to disclose specific clockspeeds.
    As for the integrated modem, Samsung has retained their Shannon 5000, a Category 20/13 modem. This modem has a peak download rate of 2 Gbps (with 8x carrier aggregration), while uploads top out at 316 Mbps. We had been wondering if Samsung would be able to squeeze in a 5G modem for this SoC, but it looks like it's just a bit too early for that. Instead, 5G can be accomplished by pairing the SoC with Samsung's 5G Exynos Modem 5100.
    The new chip is likely to be featured in the new Galaxy Note10 – Samsung will continue to use Snapdragon chips for some markets, and this could be an explanation for the new chip not having that big improvements on the part of the CPU complex as it’s aiming for performance parity with the Snapdragon. We also have to note that Samsung would have to invest the process improvements into improving power efficiency rather than raising performance.
    The chip reminds us of the Exynos 5430 from a few years ago which was also a process-shrink to the chip that ended up in the Galaxy S5, representing Samsung’s first 20nm silicon. That chip never ended up in the popular flagship products, but seemingly did serve a purpose as a pipe-cleaner and learning platform for the new process node. The new Exynos 9825 could end up in a similar situation, although being used in the Note10, it won’t nearly have an as long lifespan as we don’t expect it to power the Galaxy S11 next year.

    Anandtech: Sharp to Supply IGZO Displays to Nintendo

    In a surprising move, one of Sharp’s top executives revealed that the company will supply its IGZO displays to Nintendo. Usage of IGZO screens promises to reduce power consumption of Nintendo’s game consoles, though it is unclear which model will get a new type of LCD first.
    Katsuaki Nomura, an executive vice president of Sharp, told the Wall Street Journal that the company would supply its IGZO displays to Nintendo. The exec did not disclose specifications of the panel or which of Nintendo’s consoles will get IGZO displays first.
    The game console maker is about to release a handheld-only version of its Switch game console as well as a new version of the fully-fledged Switch. Both new devices could benefit of Sharp’s IGZO displays because of their lower power consumption and potentially higher image quality, but it remains to be seen whether Nintendo decides to shift both of its upcoming game consoles to a new type of LCDs.
    The upcoming versions of Nintendo’s Switch promise considerably longer battery life when compared to existing Switch consoles while using similar batteries. One of the key reasons why the new units feature lower power consumption is believed to be a new SoC from NVIDIA.
    Sharp and Nintendo have a long history of working together as the former designed auto stereoscopic display for the latter's 3DS console.

    Anandtech: Western Digital Reveals Ultrastar DC SN340 SSDs for Read Intensive Workloa

    Western Digital has introduced its new accelerator drives designed for very read-intensive workloads. The key feature of the Ultrastar DC SN340 Very Read Intensive (VRI) SSDs is their low read latency which is important for write-once read many applications, such as video-on-demand services, distributed databases, and emerging AI/ML workloads.
    Nowadays video streaming providers use 1 TB SATA SSDs that offer a ratio of IOPS to bandwidth that satisfies their needs in terms of numbers of parallel users/streams (RIOPS). In a bid to optimize power, costs, and the number of racks in their datacenters while still meeting their requirements, VOD services need higher-capacity drives with higher performance and specific functionality. Western Digital believes that VRI SSDs is a type of devices that will satisfy requirements of the aforementioned (and many other read-intensive) workloads.
    Carrying 3.84 or 7.68 TB of usable capacity, Western Digital’s Ultrastar DC SN340 U.2 drives optimized for write-once read many workloads are based on the company’s proprietary controller as well as 96-layer BiCS4 3D TLC NAND. With up to 3.3 GB/s sequential read speed, up to 1.5 GB/s write speed, up to 420K random read IOPS, and a 6.5 W maximum power consumption, the Ultrastar DC SN320 are substantially faster and more power efficient than SATA SSDs used by various VOD companies today.
    One key thing to note about the Ultrastar DC SN340 is that it requires all requests to be 32 KB aligned to guarantee consistent performance and appropriate endurance, so these drives are not for everyone. This is a result of the drive's Flash Translation Layer (FTL) managing data with a coarser granularity, which significantly reduces the size of the indirection tables and allows the drive to operate with less DRAM than the usual 1GB per 1TB ratio.
    In addition to video streaming services, VRI SSDs can be used for other write-once read many applications. Distributed No-SQL Databases (Apache Cassandra, MongoDB, etc.) that sequentially write in append mode and avoid overwrites can benefit from such drives and their low read latency. Furthermore, various AI and ML applications that use training while performing loads of reads also take advantage of VRI drives.

    Anandtech: AMD Rome Second Generation EPYC Review: 2x 64-core Benchmarked

    If you examine the CPU industry and ask where the big money is, you have to look at the server and datacenter market. Ever since the Opteron days, AMD's marketshare has been rounded to zero percent, and with its first generation of EPYC processors using its new Zen microarchitecture, that number skipped up a small handful of points, but everyone has been waiting with bated breath for the second swing at the ball. AMD's Rome platform solves the concerns that first gen Naples had, plus this CPU family is designed to do many things: a new CPU microarchitecture on 7nm, offer up to 64 cores, offer 128 lanes of PCIe 4.0, offer 8 memory channels, and offer a unified memory architecture based on chiplets. Today marks the launch of Rome, and we have some of our own data to share on its performance.
