Intel Downfall (Gather Data Sampling) vulnerability impacts AVX2/AVX-512 workloads

Intel Downfall

After vulnerabilities like Spectre and Meltdown were discovered in 2018, Intel processors have more vulnerabilities with the Downfall attacks that target the Gather instruction part of AVX2/AVX-512 and impact 6th generation Skylake up to 11th generation Tiger Lake processors introduced as far back as 2014. It does not affect more recent processors, and as somebody who has just purchased a laptop based on a 13th Raptor Lake processor, I guess I can breathe a sigh of relief until the next vulnerability is discovered, but people using hardware with older Intel processors will have to update the OS and suffer from a performance impact, at least for tasks leveraging AVX2 or AVX-512. The website about the Downfall vulnerability explains: Downfall attacks targets a critical weakness found in billions of modern processors used in personal and cloud computers. This vulnerability, identified as CVE-2022-40982, enables a user to access and steal data from […]

HP Chromebook 13 G1 Features Skylake Pentium or Core M Processor, 4 to 16GB RAM, and a 3200×1800 Display for $499 and Up

HP Chromebook 13 G1 is the middle ground between Google’s $1000 Chromebook Pixel and the cheap Rockchip RK3288 chromebooks, thanks to a choice of low power Skylake Core M processor,  plenty of memory, and for people who loathe 1366×768, or even 1920×1080 displays, a 13.3″ display with 3200×1800 resolution. HP Chromebook 13 G1 specifications: SoC (four options) Intel Pentium 4405Y dual core / quad thread processor @ 1.5 GHz with Intel HD Graphics 515 GPU @ 300/800 MHz (TDP: 6W) Intel Core m3-6Y30 dual core / quad thread processor @ 900 / 2.2 GHz with Intel HD Graphics 515 GPU @ 300/850 MHz (TDP: 4.5W) Intel Core m5-6Y57  dual core / quad thread processor @ 1.1 / 2.8 GHz with Intel HD Graphics 515 GPU @ 300/900 MHz (TDP: 4.5W) Intel Core m7-6Y75 dual core / quad thread processor @ 1.2 / 3.1 GHz with Intel HD Graphics 515 GPU @ […]

Intel Compute Stick STK2mv64CC Powered by Core m5-6Y57 vPro Processor is Up for Pre-order for $485

Intel announced five new Computer Sticks at the beginning of the year, and so far 4 have been launched, and the Intel Core m3 have been benchmarked showing about to double the performance compared to the Cherry Trail versions, but the most powerful model based on Core m5 had yet to be launched. The news is that if you have some spare cash, you can now pre-order Intel Compute Stick STK2mv64CC based on Core m5-6Y57 vPro processor for $485 on Amazon US with shipping scheduled for May 12, 2016. That’s quite a steep price, so let’s see what you’d get for $500: SoC – Intel Core m5-6Y57 vPro dual core/four thread processor @ 1.1 GHz/2.8GHz with Intel HD Graphics 515 @ 300MHz/900Mhz (4.5 W TDP, configurable to 3.5W and 7W) System Memory – 4 GB DDR3L @ 1833MHz dual channel memory Storage – 64 GB eMMC + micro SDXC v3.0 slot with […]

Intel Unveils 5 New Compute Stick Models Powered by Intel Atom x5 and Core M Skylake Processors

Intel has introduced 5 new models of their Compute Stick with two models based on Intel Atom x5-X8300 Cherry Trail processor, and three more power and expensive models based on Core M Skylake processors, namely Core M3-6Y30 and m5-6Y57 vPro. Let’s get started with the specifications for the two Cherry models STK1AW32SC and STK1A32SC: SoC – Intel Atom x5-Z8300 Quad-Core “Cherry Trail” processor @ 1.44 GHz/1.84 GHz and Intel HD Gen8 Graphics System Memory – 2 GB DDR3L @ 1600MHz Storage – 32 GB eMMC + micro SDXC v3.0 slot with UHS I-Support up to 128GB Video & Audio Output – HDMI 1.4b Connectivity – 802.11 b/g/n/ac Wi-Fi  and Bluetooth 4.0 (via Intel Dual Band Wireless-AC 7265) USB – 1x USB 3.0 port, 1x USB 2.0 port, 1x micro USB port for power Misc – Power button, security notch Power Supply – 5V/3A via micro USB port.

Posted on by Jean-Luc Aufranc (CNXSoft) - 5 Comments on The First Intel Core M Skylake-Y Low Power Processors: Core M3 6Y30, M5 6Y54, M5 6Y57 and M5 6Y75

The First Intel Core M Skylake-Y Low Power Processors: Core M3 6Y30, M5 6Y54, M5 6Y57 and M5 6Y75

Last year, Intel unveiled Core M Broadwell-Y processors with 4.5W TDP aimed at laptops and tablets, and offering a middle ground between the performance achieved by Atom/Celeron/Pentium processor and the more powerful Core i3/i5/i7 processors. CPU World has now released details about the new Skylake-Y Core M processor that still feature 2 cores and 4 threads, as well as a TDP of 4.5W. There are now four models: Model Cores / Threads Frequency / Turbo L3 cache Graphics GPU Frequency TDP Core m3 6Y30 2 / 4 900 MHz / 2.2 GHz 4 MB HD 515 300 / 850 MHz 4.5 Watt Core m5 6Y54 1.1 / 2.7 GHz 300 / 900 MHz Core m5 6Y57 1.1 / 2.8 GHz 300 / 900 MHz Core m5 6Y75 1.2 / 3.1 GHz 300 / 1000 MHz The processors have the same number of cores and thread, the same amount of L3 […]

Intel Skylake-U Processors Run as Low as 7.5W TDP. A Closer Look at Configurable TDP

I try to mostly cover low power systems on this blog, so when it comes to x86 processors I have a cut off TDP of 10 Watts. The next generation of Intel Skylake processors have a TDP of 15 Watts, but when I read Skylake-U lineup post on FanlessTech, I discovered Intel processors also have a configurable TDP option, and in the case of Skylake-U processor their configurable TDP (cTDP) can be as low as 7.5W or 10W depending on models. U-Processor family has Pentium and Celeron processors, but also Core i3, Core i5 and even Core i7 processors such as i7-6600U and i7-6500U clocked up to 3.4 GHz and all with a 15W TDP, but you’ll also notice a column called “cTDP Down” showing 7.5W and 10W values, which shows the great progress made by Intel with regards to low power design. So I decided to look into configurable […]
