AMD Radeon PCIe graphics card tested with a Rockchip RK3588 SBC (Radxa Rock 5B)

AMD Radeon PCIe graphics card Rockchip RK3588 SBC

When Rockchip first introduced the Rockchip RK3399 processor with a PCIe interface people initially hoped they could connect graphics card, but those hopes were quickly squashed due to a 32MB addressing limit. However, the PCIe implementation on the newer Rockchip RK3588 processor does not have such a limitation, and last November, Radxa teased a demo with an AMD Radeon Pro WX 5100 PCIe graphics card connected to the Rock 5B SBC running the glxgears demo on the Radeon GPU. I couldn’t find any instructions to reproduce this setup, but this got Jasbir interested, and he tried to do a test of his own with the Radxa Rock 5B connected to an AMD Radeon R7 520 (XFX R7 250 low-profile) through an “M.2 Key M Extender Cable to PCIE x16 Graphics Card Riser Adapter” ($14 plus taxes on Aliexpress) and powered by an LR1007 120W 12VDC ATX board. The experiment was […]

AMD Ryzen Z1 “Zen4” processors target Windows-based handheld gaming consoles

AMD has just unveiled the new power-efficient Ryzen Z1 “Zen4” Series processor family designed for handheld gaming consoles running Windows and equipped with AMD RDNA 3 architecture-based graphics. The new series features two processors at launch, namely the Ryzen Z1 hexa-core processor with 4 RDNA 3 Compute Units and the Ryzen Z1 Extreme octa-core processor with 12 RDNA 3 Computer Units for “ultimate high-performance for handheld gaming”. Highlights of Ryzen Z1 and Z1 extreme specifications: Both processors support LPDDR5/LPDDR5x memory, and USB4 interface, as well as the following AMD technologies: AMD Link – Mobile app to connect your phone, tablet, TV, or Windows-based PC, and stream games. AMD Radeon Super Resolution – In-driver feature upscaling lower resolutions set in-game to the native resolution of the active display for higher FPS performance. AMD Radeon Boost – Dynamically lowers the resolution of the entire frame when fast on-screen character motion is detected […]

AMD Ryzen Embedded 5000 processors launched for networking applications

We first spotted the AMD Ryzen Embedded 5000 processors in a micro-ATX motherboard last August, but AMD has now only announced the availability the of Ryzen Embedded 5000 Series “Zen 3” processors designed for “always on” networking firewalls, network-attached storage systems, and other security applications. AMD also mentions the Ryzen Embedded 5000 are “power-efficient processors”, but that does not mean low power, as those embedded processors are 65 to 105W parts, and offer a step-up in performance from the 10 to 54W AMD Ryzen Embedded V3000 processors also targetting networking and storage applications. As we found out last year, four SKUs are available with the Ryzen 5950E, Ryzen 5900E, Ryzen 5800E, and Ryzen 5600E, but the specifications are a little different, as for instance, there’s no 10-core part. All four are AM4-socket processors, support two DDR4 channels up to 3200MT/s, and come with 24 PCIe Gen4 lanes, and when optionally […]

AMD Alveo MA35D media accelerator transcodes up to 32 1080p60 AV1 streams in real-time

AMD ALVEO MA350 AV1 real-time encoding card

AMD Alveo MA35D media accelerator PCIe card is based on a 5nm ASIC capable of transcoding up to 32 Full HD (1080p60) AV1 streams in real-time and designed for low-latency, high-volume interactive streaming applications such as watch parties, live shopping, online auctions, and social streaming. AMD says the Alveo MA35D utilizes a purpose-built VPU to accelerate the entire video pipeline, and the ASIC can also handle up to 8x 4Kp60, or 4x 8Kp30 AV1 streams per card. H.264 and H.265 codecs are also supported, and the company claims its “next-generation AV1 transcoder engines” deliver up to a 52% reduction in bitrate at the same video quality against “an open source x264 veryfast SW model”. AMD Alveo MA350 highlights: Auxiliary CPU – 2x 64-bit quad-core RISC-V to perform control and board management tasks AI Processor – 22 TOPS per card for AI-enabled “smart streaming” for video quality optimization Memory – 16GB […]

Year 2022 in review – Top 10 posts and statistics

It’s the last day of the year and the time to look at some of the highlights of 2022, some traffic statistics from CNX Software website, and speculate on what 2023 may bring us. The semiconductors shortage continued in 2022, but things are looking brighter in 2023 with the full reopening of the world mixed with forecasts of difficult economic times that should keep the demand/supply equation in check. On the Arm processor front the biggest news of the year, at least in this corner of the Internet, was the launch of the Rockchip RK3588 octa-core Cortex-A76/A55 processor together with interesting single board computers that we’ll discuss below. Announced last year, the Amlogic A311D2 octa-core Cortex-A73/A53 was finally made available in a few SBC’s, and we finally got some news about the Amlogic S928X Cortex-A76/A55 SoC showcased in 8K TV boxes, but we have yet to see it in action.

AMD unveils low-cost Artix UltraScale+ AU7P FPGA and Zynq UltraScale+ ZU3T MPSoC

AMD UltraScale AU7P FPGA UltraScale ZU3T MPSoC

AMD has added two new low-cost, low-power members to its UltraScale+ family with the Artix UltraScale+ AU7P FPGA and the Zynq UltraScale+ ZU3T MPSoC. Both devices are manufactured with the 16nm FinFET process and offer entry points to the transceiver-based UltraScale+ family with features such as high I/O-to-logic density, UltraRAM, DSP, and more. AMD Artix UltraScale+ AU7P FPGA The new AU7P FPGA is the smallest from the Artix UltraScale+ family with four 12.5Gbps transceivers, up to 82K system logic cells, 216 DSP slices, 4.9 Mbit RAM, and 248 I/Os. It is offered in a 10.5 x 8.5mm InFO package. The company says the chip provides up to 50% lower static power, 20% more I/O-to-logic ratio, and twice as many 3.3V HDIO compared to the AU10P device. The AU7P is designed for space-constrained and/or power-sensitive applications such as medical imaging, machine vision, professional cameras/monitors, and automotive radar/lidar. More details may be […]

AMD launches Ryzen Embedded V3000 Zen3 processors for storage and networking applications

AMD has just launched the Ryzen Embedded V3000 family of processors with four to eight Zen3 cores, a DDR5 memory interface, twenty PCIe Gen4 lanes, and two 10GbE interfaces that make it ideal for storage and networking applications, especially since there’s no GPU at all. The new embedded processors succeed the Ryzen Embedded V2000 Zen2 family introduced two years ago, and the Ryzen V1000 processors in 2018. For some reason, AMD decided to compare the new V3000 processors against the latter and claims up to 124% greater CPU performance, 50% improved memory transfer rate, twice the number of CPU cores, and improved I/O connectivity. There are five Ryzen Embedded V3000 SKUs at launch with the V3C48, V3C44, V3C18I, V3C16, and V3C14 whose key differences can be found in the table below. The AMD Ryzen Embedded V3C18I “industrial” processor also works in sub-zero temperatures for automotive and industrial applications. Shared specifications […]

How to check TDP (PL1 and PL2 power limits) in Windows and Linux

A TDP (Thermal Design Power) value in Watts will usually be provided for Intel and AMD processors to help manufacturers design an appropriate thermal solution for a given processor, and it’s often used to estimate power consumption by consumers. But TDP is also often configurable, and manufacturers may decide to increase to decrease the value for higher performance or lower power consumption, so we’ll show you how to check the TDP value, or more exactly PL1 and PL2 power limits in both Windows 11 and Linux (Ubuntu 22.04). Note that TDP is being replaced by PBP (Processor Base Power) in newer processors, with PL1 (Long Duration) corresponding to BPB, and PL2 (Short Duration) to Maximum Turbo Power (MTP), at least on Intel chips. Check the TDP values in Windows 11 You’ll first need to install HWiNFO64 program, then start it leaving all options unticked (default), and go to Control Processor(s) […]
