Arm said the X3's advances are made possible in part by an 11 percent uplift in the instructions per clock (IPC) over the X2, marking the second consecutive year of double-digit IPC growth for the Cortex-X line. This makes the X3 the"highest-performing CPU" in Arm's portfolio.

Intel is running rings around AMD and Arm at the edgeWhat will it take to loosen the x86 giant's edge stranglehold?

Researchers find way to hack your CPU via AMD and Intel's frequency boostsScrew sports, Katie would rather watch Intel, AMD and Nvidia go at it. Having been obsessed with computers and graphics for three long decades, she took Game Art and Design up to Masters level at uni, and has been demystifying tech and science—rather sarcastically—for two years since. She can be found admiring AI advancements, scrambling for scintillating Raspberry Pi projects, preaching cybersecurity awareness, sighing over semiconductors, and gawping at the latest GPU upgrades. She's been heading the PCG Steam Deck content hike, while waiting patiently for her chance to upload her consciousness into the cloud. who cares if they hack you its not like it make a difference the updates to the cpu kill performance anyways so you might aswell pick your poison I have this issue, the frequency and the temp of CPU go with highest value while the PC is on idle , but when i open the task-manager the CPU performance becomes normal and the temp decreases to its normal value. Don't care. Don't reduce my performance to fix it like last time.

Arm jumps on ray tracing bandwagon with beefy GPU design READ MORE In addition to laptops, the Armv9 X3 is also aimed at high-end Android smartphones, where Arm expects to provide 25 percent faster performance than flagship X2-based devices, according to estimates based on simulations that averaged results from the SPECRate2017_int_base, SPECInt_base2006, and Geekbench 5 benchmarks. Arm said the X3's advances are made possible in part by an 11 percent uplift in the instructions per clock (IPC) over the X2, marking the second consecutive year of double-digit IPC growth for the Cortex-X line. But a close inspection reveals that most of these systems are either running on consumer-grade Ryzen processors or are so woefully outdated that anyone in their right mind – and with a big enough wallet – would opt for Intel's Xeon-D processors. This makes the X3 the"highest-performing CPU" in Arm's portfolio. There was a problem. "It's about the best user experience, whether you have an application where peak performance is needed or the perceived user response time is very critical," said Chris Abernathy, a lead CPU architect and fellow in Arm's central engineering organization, in a briefing with journalists. The Epyc 3251 processors powering both of Supermicro's AMD-based edge appliances are based on an ageing 14nm manufacturing process. Arm plans to offer the X3 design through its Total Compute Solutions program, which provides a collection of"purpose-built" chip design configurations that pull together various technologies, including its expanding portfolio of GPU designs. The chipmaker's Ryzen Embedded processor line, which targets IoT and low-power edge applications, has had an update more recently – last week in fact.

That program will also offer a new Armv9 Cortex-A715 CPU design, which Arm has deemed the"workhorse" among its set of chip blueprints for high-performance devices. But don't get too excited. Designed with a focus on delivering high sustained clock speeds, the A715 is estimated to provide 20 percent better power efficiency and five percent faster performance than the A710 design introduced last year. To balance things out, Arm refreshed last year's Armv9 Cortex-A510 Little core to provide five percent greater efficiency while delivering the same performance. The edge and IoT is probably a relatively low volume market for AMD, and validation for these environments takes time and can be costly – but at this point why bother? It looks very much like AMD just had a bunch of 2000-series Ryzen processor dies sitting around, so why not deploy them? At a time when supply chain constraints mean customers will take whatever they can get their hands on, it's not a bad idea. We're told these CPUs feature a second-generation Armv9 architecture that brings in an Asymmetric Memory Tagging Extension that is seemingly useful for catching exploitable memory corruption bugs, such as buffer overflows and heap overwrites; and Enhanced Privileged Access Never, or EPAN, which is a step up from that prevents the OS from accidentally accessing unexpected unprivileged data. Arm wants to use cash from planned IPO to fuel growth MEANWHILE When the X3, A715, and A510 cores are combined in a processor, Arm said, they can can provide double-digit increases in multi-threaded performance compared to configurations using last year's X2, A710, and A510 cores. In AMD's defense, its chips are cheaper – at least on paper. In AMD's defense, its chips are cheaper – at least on paper.

This multi-threaded boost can range from 12 percent to 23 percent depending on the core arrangement, which is based on performance estimates for the Geekbench 5 MT benchmark. And, according to Arm, if you were to go to eight X3 cores and four A715 cores, multi-threaded workloads would be boosted by 125 percent compared to a processor using one X2 core, three A710 cores, and four A510 cores from last year, based on a simulation of the design. But it's hard to draw a value comparison without without pitting them against each other in real-world testing. And yes, that's 12 cores versus eight, so a performance boost would be expected. The eight-core arrangement would be aimed at things like smart TVs, and the 12-core at things like laptops and PCs. But suffice to say, our money would be on Intel, at least in this arena. The DynamIQ Shared Unit, or DSU, Arm's glue logic for its CPU core clusters, has, in line with this, been updated to support up to 12 of these latest cores and 16MB of L3 cache. Arm's efficiency edge But enough about AMD.

"We are offering many ways for our partners to innovate and, in some cases, reach new, previously unimagined levels of performance," said Saurabh Pradhan, director of product management at Arm. What about Arm? Where are the Arm edge appliances? Let's get something out of the way: Arm will absolutely dominate far-edge compute applications, and not even by a little bit. Pradhan said these simulations of core configurations is helping Arm uncover new layouts that can benefit devices of varying requirements. "For example, we noticed that especially in very thermally constrained environments, the Cortex-A700 series is actually a better ROI for sustained workloads," he said. These chips manage desktop-class performance at a fraction of the power required by their x86 contemporaries."Now, this is a statement for one specific benchmark. But the goal here is to make sure that we provide a solid portfolio for our partners so that they can pick and choose what they want.
