Pentium is gone, but dual-cores live on: “Intel 300” is coming

News, Processors | | Jan Olšan

Last year, Intel announced the end of the once famous Celeron and Pentium brands that have since been relegated to the bottoms of lowend, with cheapest CPU lines no longer bearing any special name. Such E-Core-only “Intel Processors” have appeared in laptops, but desktop has note yet caught up with the rebranding – until now. Desktop “Intel processor” SKUs will however be based on the big cores. You’ll still only get dual-core, though. Read more “Pentium is gone, but dual-cores live on: “Intel 300” is coming” »

Intel’s 4nm process: Meteor Lake processors will reach 5.1+ GHz

News, Processors | | Jan Olšan

Not long ago, we wrote here about the clock speeds expected from Intel’s first 4nm processors, the mobile Meteor Lake. There were widespread concerns that this new technology would again suffer from clock speed regression, as seen with Intel’s early 10nm process. Recently, however, things are starting to look positive, and so Meteor Lake could end up doing very well, with these processors running above the 5.0 GHz threshold.

AVX10 seeks to replace AVX-512, will work on big.LITTLE CPUs

Analysis, News, Processors | | Jan Olšan

Yesterday we reported that x86 processors – at least those from Intel – will get Advanced Performance Extensions (APX), a major change in the programming of these CPUs. But Intel is also planning big changes to SIMD instructions with AVX10 technology, which will unify vector extensions whose subsets are now a mess, and should also address the problem of big.LITTLE processors. But this may in turn kill the true 512-bit SIMD capability of AVX-512. Read more “AVX10 seeks to replace AVX-512, will work on big.LITTLE CPUs” »

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.

Intel LGA 1851: No changes and ending support for current coolers?

CPU coolers, News, Processors | | Ľubomír Samák

There are reports that the upcoming Intel LGA 1851 socket will have different cooler requirements. This is even while maintaining the same physical dimensions of the mounting holes or processors as such. A forceful way of selling new coolers? This may not be the case and the real reason may be purely technical. And we probably have some idea why processors from the Arrow Lake generation onwards will benefit from more downforce.

Ryzen 5 7500F will launch at the end of July, but only in China

News, Processors | | Jan Olšan

Just recently, information surfaced online about a new AMD processor with Zen 4 architecture that could be the most affordable model yet on the AM5 platform – the Ryzen 5 7500F, which would be a six-core with disabled graphics that, at a low enough price, could be the answer to Intel’s popular Core i5-13400F. But it looks like, as with the Ryzen 5 5600X3D, we won’t be able to get our hands on it, at least not for now. Read more “Ryzen 5 7500F will launch at the end of July, but only in China” »

Raptor Lake Refresh: Core i7-14700K has 20 cores, benchmarks leak

News, Processors | | Jan Olšan

There are currently news about AMD releasing the Ryzen 5 7500F CP as a cheaper alternative to the 7600 hexacore, but there’d also big news in the Intel camp – the first processor from Raptor Lake Refresh generation, which is expected to come in Fall. Info about the Core i7-14700K has now leaked. This tier of CPUs was already attractive in the previous generations, and now it’s getting bigger with more cores added.

Intel Arrow Lake and Lunar Lake CPUs will reportedly drop HT

News, Processors | | Jan Olšan

It was recently revealed that Intel will end the distinctive “Core iNumber” CPU branding that has served it since the groundbreaking Nehalem architecture. But it might also abandon a much more important constant that came with these processors: the ability to process two threads one a big core known as Hyper Threading or HT technology (which originated in Pentium 4, but it was only after its return in Nehalem that it really shone).

Ryzen 7 7800X3D: Ahead of Core i9 for gaming at 40% power draw

Extra tests, Processors | | Ľubomír Samák

The most popular Ryzen 7000 with 3D V-cache obliterates competition in its targeted environment. Intel doesn’t measure up to the Ryzen 7 7800X3D in a comparable price range in terms of speed, and even if someone disregards price and sees the Core i9-13900K(S) as a an apt competitor, when comparing power draw, everyone’s appetite for Intel will go away. Their efficiency is… incomparable, as each is at a different end of the spectrum. Read more “Ryzen 7 7800X3D: Ahead of Core i9 for gaming at 40% power draw” »

AMD quietly launches big.LITTLE, Zen 4c-based Phoenix2 confirmed

News, Processors | | Jan Olšan

Many like to diss Intel for hybrid processors but leaks has long been showing that AMD is also preparing their own take on it – the “LITTLE Phoenix” or Phoenix2 APU, to be used in cheaper mobile Ryzen 7000 SKUs. Phoenix2 is to feature Zen 4 big cores and Zen 4c as little cores, which is a compact redesign recently introduced in servers. Now this hybrid SoC has indeed appeared and AMD has officially confirmed it on their website. Read more “AMD quietly launches big.LITTLE, Zen 4c-based Phoenix2 confirmed” »

Ryzen 5 5600X3D launches this week, but exclusively in the U.S.

News, Processors | | Jan Olšan

AMD is reportedly going release a new AM4 processor after more than a year, a cheaper derivative of the Ryzen 7 5800X3D called Ryzen 5 5600X3D, which would include the game-boosting 3D V-Cache, but with only six cores. Initially, there were some doubts, but it looks like it is real. Its release and availability in the US is already confirmed to be due this week. It’s less clear for the rest of the world, however.

Intel CPU launch plans: refreshes, Meteor Lake and Arrow Lake

News, Processors | | Jan Olšan

Intel has recently hinted at release of new desktop processors when the company announced the Intel InnovatiON event which was used to unveil the 12th and 13th generation Core desktop processors (Alder Lake, Raptor Lake for socket 1700) in previous years. However, it’s likely that only a paper launch will come directly at this event and the real CPUs will come out later. Unofficial reports from Chinese leakers now reveal when that will be.

Conflict of interests? ARM wants Intel to buy part of company

News, Processors | | Jan Olšan

Ever since Nvidia’s plan to acquire ARM failed, the Softbank fund has been aiming to monetise the company through an IPO instead, in which a portion of ARM’s stock would be sold not to a single acquiring party but through the mechanisms of open stock trading. It turns out this could have curious results, because it seems the initial public offering could end up with Intel, the main competitor, being one of the owners. Read more “Conflict of interests?

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.
