RISC-V International, the global standards organization, today announced that the RVA23 Profile is now ratified. RVA Profiles align implementations of RISC-V 64-bit application processors that will run rich operating systems (OS) stacks from standard binary OS distributions. RVA Profiles are essential to software portability across many hardware implementations and help to avoid vendor lock-in. The newly ratified RVA23 Profile is a major release for the RISC-V software ecosystem and will help accelerate widespread implementation among toolchains and operating systems.

As the steward of the RISC-V standard, RISC-V has more than 80 technical working groups that collectively advance the capabilities of the RISC-V ISA. RISC-V addresses the need for portability across vendors with standard ISA Profiles for applications and systems software. Each Profile specifies which ISA features are mandatory or optional, providing a common target for software developers. Mandatory extensions can be assumed to be present, and optional extensions can be discovered at runtime and leveraged by optimized middleware, libraries, and applications. To be ratified, the RVA23 Profile underwent a lengthy development, review, and approval process across numerous working groups, before receiving the final ratification vote by the RISC-V Board of Directors.

While we are all used to having a system with a CPU, GPU, and, recently, NPU—X-Silicon Inc. (XSi), a startup founded by former Silicon Valley veterans—has unveiled an interesting RISC-V processor that can simultaneously handle CPU, GPU, and NPU workloads in a chip. This innovative chip architecture, which will be open-source, aims to provide a flexible and efficient solution for a wide range of applications, including artificial intelligence, virtual reality, automotive systems, and IoT devices. The new microprocessor combines a RISC-V CPU core with vector capabilities and GPU acceleration into a single chip, creating a versatile all-in-one processor. By integrating the functionality of a CPU and GPU into a single core, X-Silicon's design offers several advantages over traditional architectures. The chip utilizes the open-source RISC-V instruction set architecture (ISA) for both CPU and GPU operations, running a single instruction stream. This approach promises lower memory footprint execution and improved efficiency, as there is no need to copy data between separate CPU and GPU memory spaces.

Called the C-GPU architecture, X-Silicon uses RISC-V Vector Core, which has 16 32-bit FPUs and a Scaler ALU for processing regular integers as well as floating point instructions. A unified instruction decoder feeds the cores, which are connected to a thread scheduler, texture unit, rasterizer, clipping engine, neural engine, and pixel processors. All is fed into a frame buffer, which feeds the video engine for video output. The setup of the cores allows the users to program each core individually for HPC, AI, video, or graphics workloads. Without software, there is no usable chip, which prompts X-Silicon to work on OpenGL ES, Vulkan, Mesa, and OpenCL APIs. Additionally, the company plans to release a hardware abstraction layer (HAL) for direct chip programming. According to Jon Peddie Research (JPR), the industry has been seeking an open-standard GPU that is flexible and scalable enough to support various markets. X-Silicon's CPU/GPU hybrid chip aims to address this need by providing manufacturers with a single, open-chip design that can handle any desired workload. The XSi gave no timeline, but it has plans to distribute the IP to OEMs and hyperscalers, so the first silicon is still away.

AI workloads are split into two different categories: training and inference. While training requires large computing and memory capacity, access speeds are not a significant contributor; inference is another story. With inference, the AI model must run extremely fast to serve the end-user with as many tokens (words) as possible, hence giving the user answers to their prompts faster. An AI chip startup, Groq, which was in stealth mode for a long time, has been making major moves in providing ultra-fast inference speeds using its Language Processing Unit (LPU) designed for large language models (LLMs) like GPT, Llama, and Mistral LLMs. The Groq LPU is a single-core unit based on the Tensor-Streaming Processor (TSP) architecture which achieves 750 TOPS at INT8 and 188 TeraFLOPS at FP16, with 320x320 fused dot product matrix multiplication, in addition to 5,120 Vector ALUs.

Having massive concurrency with 80 TB/s of bandwidth, the Groq LPU has 230 MB capacity of local SRAM. All of this is working together to provide Groq with a fantastic performance, making waves over the past few days on the internet. Serving the Mixtral 8x7B model at 480 tokens per second, the Groq LPU is providing one of the leading inference numbers in the industry. In models like Llama 2 70B with 4096 token context length, Groq can serve 300 tokens/s, while in smaller Llama 2 7B with 2048 tokens of context, Groq LPU can output 750 tokens/s. According to the LLMPerf Leaderboard, the Groq LPU is beating the GPU-based cloud providers at inferencing LLMs Llama in configurations of anywhere from 7 to 70 billion parameters. In token throughput (output) and time to first token (latency), Groq is leading the pack, achieving the highest throughput and second lowest latency.

Intel has begun rolling out software binaries compiled with support for upcoming Advanced Performance Extensions (APX) and Advanced Vector Extensions 10 (AVX10) instruction set extensions in their Clear Linux distribution, ahead of any processors officially supporting these capabilities launching. Clear Linux is focusing first on optimized APX and AVX10 versions of foundational software libraries like glibc and Python. This builds on Clear Linux's existing support for optimized x86-64-v2, v3, and v4 code paths, leveraging the latest microarchitectural features of each Intel CPU generation. The rationale is to prepare Clear Linux to fully leverage the performance potential of next-generation Intel Xeon server processors, code-named Granite Rapids, expected to launch later this year.

Granite Rapids will introduce AVX10.1/512 instructions as well as the new APX capabilities, which are currently not well documented implementation wise. By rolling out APX/AVX10 support in software now, Clear Linux aims to have an optimized ecosystem ready when the new processors officially ship. Initially, APX and AVX10 support is being added using the existing GCC compiler. Still, Clear Linux notes they will transition to using the upcoming GCC 14 release with more mature support for these instruction sets. The goal is to eventually have many Clear Linux packages compiled with APX/AVX10 code paths to maximize performance on future Intel CPUs. This continues Clear Linux's strategy of leveraging Intel's latest hardware capabilities in software.

EK, the leading manufacturer of premium liquid cooling gear, is bearing good news for liquid cooling enthusiasts, announcing the availability of compatible GPU water blocks for the OG Editions of the ASUS TUF Gaming GeForce RTX 4090 graphics cards. Due to the physical differences in the PCB of the OG Edition GPU, it requires a different GPU water block than what would usually fit the 4090 Strix and TUF models.

After researching the market and examining the GPU itself, EK's RnD team has concluded that the OG Edition 4090 TUF is compatible with the EK-Quantum Vector² Strix/TUF RTX 3090 Ti water block and EK-Quantum Vector² Strix/TUF RTX 3090 Ti ABP (Active Backplate) Set. The models of the GPU are not to be confused with the "OC" marking but with the newly added "OG" suffix in the product name. Here, EK would like to thank the Reddit community as a useful source of information.

EK, the premium water-cooling gear manufacturer, is launching a new universal distribution plate - EK-QuantumX Loophole Distroplate D5 PWM. The distro features an entire wall filled with ports, allowing users to pick the ones that fit their unique build perfectly. As the waterway has no prebuilt inner channels but rather an "open space" internal structure, the user can custom-route tubes from one port to another within the distro itself using micro 90-degree angled adapters and micro HDP or HDC fittings. This unprecedented flexibility and customizability is also reflected in the universal mounting on 140 mm fan mounting holes, enabling compatibility with almost any modern PC case. This product does not feature any LED illumination.

The EK-QuantumX Loophole Distroplate D5 PWM is a custom water-cooling reservoir, routing, and pump solution that can be mounted on 140 mm fan patterns inside the chassis (provided there's enough room for it in the case). It is unique in the sense that there are no pre-made channels for coolant routing. Instead, the channels are built by the user. The distro can be mounted on practically any 280 mm (2x140mm) mounting point, and with angled brackets (sold separately), users can mount it 90° to a 120 mm or 140 mm fan mount. It is part of the QuantumX Line aimed at enthusiasts who wish to stand out. The product comes in two finishes: Silver and Black.

Ever since the creation of A64FX for the Fugaku supercomputer, Fujitsu has been plotting the development of next-generation CPU design for accelerating AI and general-purpose HPC workloads in the data center. Codenamed Monaka, the CPU is the latest creation for TSMC's 2 nm semiconductor manufacturing node. Based on Armv9-A ISA, the CPU will feature up to 150 cores with Scalable Vector Extensions 2 (SVE2), so it can process a wide variety of vector data sets in parallel. Using a 3D chiplet design, the 150 cores will be split into different dies and placed alongside SRAM and I/O controller. The current width of the SVE2 implementation is unknown.

The CPU is designed to support DDR5 memory and PCIe 6.0 connection for attaching storage and other accelerators. To bring cache coherency among application-specific accelerators, CXL 3.0 is present as well. Interestingly, Monaka is planned to arrive in FY2027, which starts in 2026 on January 1st. The CPU will supposedly use air cooling, meaning the design aims for power efficiency. Additionally, it is essential to note that Monaka is not a processor that will power the post-Fugaku supercomputer. The post-Fugaku supercomputer will use post-Monaka design, likely iterating on the design principles that Monaka uses and refining them for the launch of the post-Fugaku supercomputer scheduled for 2030. Below are the slides from Fujitsu's presentation, in Japenese, which highlight the design goals of the CPU.

EK, the leading computer cooling solutions provider, is introducing White Editions of EK-Quantum Velocity² and EK-Quantum Vector² water blocks. These GPU and CPU water blocks feature EK's iconic white acetal standouts, with the Vector² GPU water block also having a white terminal. This AM5 water block is built upon an award-winning, market-recognized Velocity² platform that has so far received an iF Design award, a European Hardware Award, and a CES innovation award.

The Velocity² series water blocks outshined their predecessor and took over the market lead. Embedded in the Velocity² is a socket-specific, high-performance cooling engine with low hydraulic flow restriction. This is achieved through a combination of mounting pressure and cold plate geometry specifically tailored for the IHS and the die layout of the AMD AM5 socket. The asymmetric jet plate cutout also enables the flow to be directed into the areas that need it the most.

EK, the premium water-cooling gear manufacturer, is launching a new distro plate for the Lian Li O11D XL chassis. The distro has a built-in EK-Quantum Lumen screen, a 7" IPS monitor that can be seen from the front of the case. It is designed to provide advanced water cooling with the latest 3rd-generation SATA-powered D5 pump, removing the need for additional 4-pin Molex cables. The Reflection² series distribution plates are EK-Matrix7 compliant.

The EK-Quantum Reflection² PC-O11D XL D5 PWM D-RGB - Screen Edition is a custom water-cooling reservoir, routing, and pump solution that seamlessly fits into the front of the case showing off a beautiful 7" IPS screen with an aluminum frame. This waterway is also equipped with six innovative push-in ports that come with female G1/4" threaded adapters. The idea is that users can easily assemble the whole radiator + fittings + tubing combo and use these push-in adapters to simply slide it into the distribution plate. The bottom radiator is mounted via a special metal bracket.

A few days ago, PowerColor teased its upcoming flagship Radeon RX 7900 XTX Liquid Devil graphics card. Today, we have the first images coming from CornerJack of Overclocking.com. According to his unboxing, we can see the new collaboration of EK and PowerColor to create the latest Radeon RX 7900 XTX Liquid Devil graphics card with nickel-plated copper block based on Quantum Vector technology, addressable RGB illumination through the acrylic top, and a black backplate that is also presumably RGB illuminated to match the block as well. Powered by triple 8-pin connectors, the card features a BIOS switch that allows users to switch between OC BIOS and unleash BIOS modes, with the latter presumably having higher power limits.

In the box, besides the card, there is a provided EK loop pressure test that tests if any leaks are occurring. You can see the card's pictures below and look at the complete unboxing by CornerJack here.

EK, the premium water-cooling gear manufacturer, is launching the EK-Quantum Vector² water block for the ASUS TUF models of the new AMD Radeon RX 7900 GPUs. This water block has been engineered to fit both versions of these GPUs, the XTX and the XT. The EK-Quantum Vector² TUF RX 7900 XTX D-RGB is a fully EK-Matrix7 compatible liquid cooling solution engineered exclusively for ASUS TUF Radeon RX 7900 XT and XTX GPUs. It encompasses a Vector² series water block and a black-anodized aluminum backplate in the same package. Like the rest of the Vector² series water blocks, its looks are dominated by minimalistic straight lines and the backplate coming around the side of the GPU to cover the PCB in its entirety.

What differs from all other Vector² water blocks is that the cooling engine for this water block has been rotated by 90°, making the fins perpendicular to the die. For optimal delta, the coolant flows over the Graphics Core Die first and Memory Cache Die after. Consequently, all MCDs get the same coolant temperature thanks to the high-precision 3D-machined acrylic jet insert.

The long-awaited December 13th has finally arrived with the latest AMD Radeon RX 7000 Series GPUs being released. More good news is that EK, the premium water-cooling gear manufacturer, is ready with the EK-Quantum Vector² water blocks for the reference models of the new AMD Radeon RX 7900 XTX GPUs. The compatible water blocks can be found HERE.

But to celebrate the availability of these GPUs, EK Water Blocks is making a limited run of these special AMD Radeon Edition GPU water blocks. This water block fits reference PCB designs of the Radeon RX 7900 XTX GPUs, but we recommend you refer to the EK Cooling Configurator for a precise compatibility match.

EK­, the premium water-cooling gear manufacturer, is introducing a new portfolio of Quantum Line terminals from the Scalar² family. The two products that come in the first wave include EK-Quantum Scalar² Terminal - Plexi and EK-Quantum Scalar² DirectLink Terminal - Plexi. These are see-through acrylic versions of the current terminals for Vector² water blocks and Vector² ABP sets. In the future, the Scalar² family will grow. So, you can expect more similar products like SFF terminals, multi-GPU terminals, and much more.

This see-through terminal replaces the stock black POM acetal terminal on the Vector² GPU water blocks. It has four G1/4" ports, two on the top and two at the bottom. Sleek magnetic covers can be used to conceal the terminal screws that allow rotation of the branding when the GPU water block is inverted in the case or is being used on a vertical GPU mount. The screws and magnetic plate should be re-used from the original terminal and are not a part of the Scalar² package.

Amazon's AWS division has been making Graviton processors for a few years now, and the company recently announced its Graviton3 design will soon to available in the cloud. Today, we are witnessing a full launch of the Graviton3 CPUs with the first instances available in the AWS Cloud. In theC7g instances, AWS customers can now scale their workloads across 1-64 vCPU instance variants. Graviton3's 64 cores run at 2.6 GHz clock speed, 300 GB/sec maximum memory bandwidth, DDR5 memory controller, 64 cores, seven silicon die chiplet-based design, 256-bit SVE (Scalable Vector Extension), all across 55 billion transistors. Paired with up to 128 GiB of DDR5 memory, these processors are compute-intensive solutions. AWS noted that the company used a monolithic computing and memory controller logic design to reduce latency and improve performance.

One interesting thing to note is the motherboard that AWS hosts Graviton3 processors in. Usually, server motherboards can be single, dual, or quad-socket solutions. However, AWS decided to implement a unique solution with three sockets. This tri-socket setup is designed to see each CPU as an independent processor, managed by a Nitro Card, which can handle exactly three CPUs. The company notes that the CPU is now in general availability with C7g instances and you can see it below.

EK, the leading computer cooling solutions provider, is introducing new Vector² water blocks, this time for the MSI TRIO and SUPRIM GeForce RTX 3090 Ti GPUs.

Minimalistic straight lines dominate the new look of the next-gen water blocks.

The 3rd-generation Vector cooling engine combines the jet plate with a 3D machined Plexi insert to improve flow distribution and thermal performance. This new cooling engine is still based on an Open Split-Flow cooling engine design, which proved to be a superior solution for GPU water blocks. It is characterized by low hydraulic flow restriction, meaning it can be used with weaker water pumps or pumps running on low-speed settings and still achieve top performance. Great care was taken to achieve a symmetrical flow domain by utilizing an internal bridge to secondary components. This was done to ensure the cooling of secondary components without sacrificing flow distribution over the GPU core.

EK, is happy to announce that several AMD-based GPU water blocks are compatible with the new AMD Radeon RX 6000 series expansion.
