Leak gives a peek at the clock speed of Intel Arrow Lake CPUs

News, Processors | | Jan Olšan

Last week, we covered the clock speeds of Zen 5 Ryzen 9000 CPUs. Now another information leak uncovered what clock speeds possibly reached by the Arrow Lake processors from Intel. This is an important piece of the puzzle, as we already know what the IPC of their cores will be, but the clock speeds were a big unknown, given how the new wider architecture and TSMC’s 3nm node could have drastically lowered them. And with that, the performance. Read more “Leak gives a peek at the clock speed of Intel Arrow Lake CPUs” »

Zen 5: AMD’s most innovative core since the original Zen [analysis]

Analysis, Processors | | Jan Olšan

It’s roughly two weeks until AMD releases processors with the new Zen 5 architecture. This week, we finally got proper details on these CPUs’ architecture, which AMD revealed at the Tech Day event. So, we can now break down the changes the company has made to the core, compared to Zen 4 – and they’re pretty extensive, probably more so than they seemed in June. And AMD also reiterated its promise of a 16% increase in IPC for these CPUs. Read more “Zen 5: AMD’s most innovative core since the original Zen [analysis]” »

Oryon, the Nuvia ARM core of Snapdragon X: Architecture analysis

Analysis, News, Processors | | Jan Olšan

At Computex 2024, Intel introduced the new Lion Cove and Skymont architectures, which we covered in detail. AMD also shared a peek at their competing Zen 5 core, but with little detail, so we’ll have to wait with our analysis of the architecture. But there’s a new ARM-based challenger entering the fray – the Snapdragon X Elite currently coming to laptops. And Qualcomm has now also finally teased its “Nuvia” Oryon architecture.

Skymont architecture analysed: Intel little core outgrows the big?

Analysis, News, Processors | | Jan Olšan

Intel unveiled their next-gen Lunar Lake mobile processor at Computex 2024. It will power Copilot+ PCs with its NPU and is supposed to be very power efficient, but it’s extremely interesting mainly because of the new CPU architectures, which will power future Arrow Lake desktop CPUs. Ironically, the star of this generation might actually be the little efficient E-Core accompanying the big P-Cores. Its architecture seems to have taken a giant leap.

Intel’s new P-Core: Lion Cove is the biggest change since Nehalem

Analysis, News, Processors | | Jan Olšan

Intel revealed its next-gen Lunar Lake mobile processor at Computex 2024, to be released this summer. It will power Copilot+ PCs with its fast NPU and is supposed to be highly power efficient, but it’s also extremely interesting because its new CPU architectures are also coming to future Arrow Lake desktop CPUs. First up, we’ll take a look at the big P-Core architecture, which represents the biggest changes in many years. Read more “Intel’s new P-Core: Lion Cove is the biggest change since Nehalem” »

Ryzen 9000 is here. Zen 5 architecture, IPC and model specs

News, Processors | | Ľubomír Samák

After a long wait, it’s here. During its presentation at Computex 2024, AMD unveiled the Ryzen 9000 desktop CPUs, the first of the generation of CPUs based on the Zen 5 architecture. We now have confirmed specifications and also the IPC of this architecture (the officially stated value, at least). According to AMD, these are the fastest “consumer PC” processors of today, and the company has already shown the first performance claims. Read more “Ryzen 9000 is here.

Windows 11 stops working on more processors, requires SSE4.2

News, Processors | | Jan Olšan

This year, the vague uncertainty about Windows 11 not supporting older computers turned into reality, as the OS began using the POPCNT instruction, causing it to stop working on many processors. However, this was not all and the requirements may increase further. In fact, now Windows 11 is starting to require additional instruction set extensions that will shut down more processor families, including Phenoms and the first APUs.

Zen 6 finally brings more advanced 2.5D chiplets, has RDNA 5 GPU

News, Processors | | Jan Olšan

So far, little information has emerged about what to expect from AMD Ryzen processors with the Zen 6 architecture. The core itself should be an evolution of Zen 5, given AMD’s model resembling “tick-tock”, where even-numbered cores are less aggressive enhancements of tech introduced in odd-numbered ground-up redesigns. But it looks like everything else in the SoC could be a radical shift from the aging concept of Ryzen processor uncores.

AMD confirms Zen 5 details: 6 ALUs, full-performance AVX-512

News, Processors | | Jan Olšan

Zen 5-based AMD processors will launch this year (perhaps in Q3). Unlike Zen 4 which was just Zen 3 refined, Zen 5 will be another big upgrade, and according to various hints including statements by the architect Mike Clark, it could be AMD’s most interesting core since the first Zen. Interestingly, up until now, the only information about it has come from a single YouTuber source. But it has just been officially confirmed directly by AMD.

Arrow Lake CPU spotted. Missing HT and AVX-512 confirmed

News, Processors | | Jan Olšan

Couple days ago, documents leaked on Arrow Lake-S processors and Generation 800 chipsets – Intel’s next-gen desktop platform with the new LGA 1851 socket, due out in the second half of the year. Besides the things we already analysed, those documents also indicate that Arrow Lake P-cores have only one thread. This has now been confirmed by a log from testing a sample of this CPU. After 22 years, Intel processors are dropping HT. Read more “Arrow Lake CPU spotted. Missing HT and AVX-512 confirmed” »

Amazon unveils 96-core ARM Graviton4 CPU and Trainium2 AI chip

News, Processors | | Jan Olšan

Last month, Microsoft unveiled their first custom processors being developed for datacenter and Azure services. Also Amazon, which was the first of these US hyperscalers to go the custom hardware route, is now launching new CPUs for its servers. And with it Trainium2, already the second generation of an in-house developed AI accelerator. Amazon also revealed that it has already produced over two million of its CPUs.

Intel unveils Meteor Lake processors: 4nm, tiles, Xe LPG graphics

News, Notebooks, Processors | | Jan Olšan

Meteor Lake is Intel’s first processor manufactured on in-house 4nm node, an important milestone. It is also, paradoxically, Intel’s first processor manufactured at TSMC, as many of its parts are outsourced in this way – a milestone too. This is the first mainstream Intel processor to use chiplets (or tiles) and advanced 3D packaging. It’s almost and extra beyond that, that there are new CPU cores, new GPU, and a new NPU for AI acceleration. Read more “Intel unveils Meteor Lake processors: 4nm, tiles, Xe LPG graphics” »

Intel APX: x86 ISA upgrade to catch up with newer architectures

News, Processors | | Jan Olšan

Recently, Intel announced the so-called x86-S architecture – a proposal to cut legacy baggage of the x86 processor platform. Another modernization effort of the traditional instruction set used in personal computers has been announced now. Future CPUs will get Intel APX (Advanced Performance Extensions), that break through some of the historical limits of this 40-year-old ISA and brings it somewhat closer to newer architectures.

big.LITTLE by AMD: Zen 4c has the same IPC as the big Zen 4

Analysis, News, Processors | | Jan Olšan

After Intel’s hybrid CPUs, AMD is preparing its own big.LITTLE scheme that uses a mix of Zen 4 cores and a new Zen 4c variant that will be used in servers but also in laptops. However Zen4c is and at the same time is not a little core. While having much smaller footprint, it is said to be fully architecturally equivalent to the large core, including (almost?) the same performance per 1 MHz. The only little thing about it is clock speed. Read more “big.LITTLE by AMD: Zen 4c has the same IPC as the big Zen 4” »

ARM unveils record-breaking Cortex-X4 core with eight ALUs

Analysis, News, Processors | | Jan Olšan

ARM has been releasing a new generation of processor cores every year lately. This year will be no different (except for the Computex timing). ARM has unveiled a complete line of new architectures: a new Cortex-X4 “prime” big core for maximum single-threaded performance, a new medium Cortex-A720 core whose role is to provide multi-threaded performance (like Intel’s E-Core), and finally a new low-power Cortex-A520 little core.
