Intel held its annual architecture day yesterday and revealed to us a variety of developments that will soon become products, including architecture Alder lake That will reach computers this year. All the details here
Yesterday set Intel Israel is a seminar for local media which included a presentation of a variety of new technologies and developments that will become products. Architecture Day of Intel Is a theoretical and technical day which shows us in detail what changes she has made Intel In its new hardware architectures towards the launch of new products.
The amount of journalistic material on this day is very large, and we will emphasize among the hundreds (!) Pages of content the main points of interest to our readers. Let's start with the main dish for the world of computing - micro architecture Processors new.
The main topics are of course the Alder Lake building blocks, along with the graphics core technologies for the Intel Graphics division, through processors Sapphire Rapids for servers up to Ponte Vecchio, Processors Unique hybrids.
Processors Alder lake Some of the small cores
This makes Alder Lake's processors Intel Special varnish is a change from the base of the CPU core composition, in all market segments. From desktops to lightweight laptops, Intel Adds new definitions of what processing cores are and what types they exist.
The sub-player of the Alder Lake architecture is the Efficient Core, or as it is called - E-Core. For those of you who are familiar with Atom's processors Intel, This is a core that continues the architecture line Processors These cost-effective ones are codenamed Gracemont.
Intel claims that this core is efficient in a way we have never seen in the world of X86 computing. It is shown to us that at a certain point between the performance ratio and the power consumption, the core of the E-Core Able to deliver the same performance we've encountered in Skylake cores so far (Core i7 6700K or later) at 40% lower power. Alternatively, the E-Core Provide 40% additional performance in similar power consumption.
When it comes to processors with extremely low operating voltage (ultrabooks, tablets), describes Intel A situation in which a complex of four cores E-Core Unmatched efficiency versus a dual-core array of cores Skylake With HyperThreading when at a certain point for the same performance the power envelope drops to only one-fifth.
Intel guarantees e-coreCore Designed specifically to serve multi-tasking, and tampering with system components that require background resources or otherwise tasks that are poor in system requirements. To E-Core Two very clear goals one of which is to reduce load from the large cores of the system and the other is to significantly reduce the power consumption when performing this operation.
According to Intel, These are not weak cores at all compared to what the market has seen to date, and when they arrive in respectable groups their power may be reminiscent Processors Whole until recently assembled computer systems.
Big cores, big promises
The main player of Alder Lake processors (at least in our opinion) is Performance Core Or nicknamed P-Core. This is a primary processing core built from scratch for Alder lake And other futures products.
When Intel claims to have made dramatic improvements to the main processing cores of future processors, it is not kidding. The P-Core Of Alder Lake processors is the most meaty processing core we've seen from Intel so far, and probably in the field ofx86 To the domestic market to this day.
First-rate cache memory is a critical component of the core's power and processing content. Here she did Intel And significantly increased the buffers and storage volumes of information passing through the cache.
Also volume זיכרון The second-level cache sees a 25% increase in volume compared to the processing cores we have known so far. This, apart from some improvements in reading mechanisms.
Intel compared P-coresCore The news (code name Golden Cove) for the Cypress Cove cores we know from Rocket Lake processors at the same 3.3GHz operating frequency. At this frequency, the average performance improvement of P-coresCore Is 19 percent. It is important to remember that there is another component that affects the actual performance and that is the operating frequency we get in the processors.
People Intel Did not share with us the actual operating frequencies we will encounter in Alder Lake processors (there may still be recent adjustments, or they may prefer to surprise us). For processors Rocket lake There are high operating frequencies, so we wonder - how much higher can it already be? Do they appear to have multiple cores operating at a frequency higher than 5 GHz simultaneously?
It took Intel a considerable amount of time to develop the architecture Alder lake, And now that we're at the finish line she's promising the wait is going to be worth it.
Make everything work together
After realizing that the processorsAlder lake Will contain a combination of small cores and large cores - how is everything supposed to work? How does an asymmetrical array of cores divide the work stand?
After all, the software component and the material component must live in harmony in order to get results in the field. Well, at the level closest to "irons", she developed Intel The traffic cop of traffic loads between the second processor cores. Pictured, by the way, is the Alder Lake processor in the fullest lineup that will be available in desktop processors. This processor includes eight P-coresCore And eight cores E-Core. Notice how small the E- cores areCore (In light blue) in comparison.
The Intel Thread Director is a hardware component whose job is to navigate loads between P-coresCore To E-Core. If loads become small to large, it is responsible for pulling the responsibility from small cores and throwing it on the big ones and also in the opposite direction. The Thread Director is a component that arrives even before the various software components impose processing tasks on the various cores. If an operation becomes a background operation, the system will take care of clearing loads in the large cores and transfer the same operations to the small cores. This may actually increase the processing power for heavy tasks compared to what we are familiar with today, with all the segment operations of the various operating systems.
People Intel We have been told that there is a close collaboration with Microsoft to ensure that Windows 11 recognizes Alder lake processors and forgets about them in harmony. When asked about Windows 10 and Linux, we heard that performance optimizations are being done and will continue to be done there as well.
When everything plays together
Processors Alder lake Are expected to hit the market in three different configurations first. The display with the greatest processing power will reach the desktop processors and do so in a brand new bracket with 1700 touch points. The LGA1700 bracket will be used for processors Alder lake And this is the first time a desktop bracket has used such a large amount of touch points for standard processors (to remind you, in the last decade we have used between 1150 and 1200 of them).
The most powerful configuration for desktop processors will be with eight P-coresCore And eight cores E-Core. For the P- coresCore There is HyperThreading technology and e-core coresCore No. As a result we get a 24-thread processor.
There is a preservation of the nature of the built-in graphics cores we were familiar with in Rocket Lake's processors Intel When unfortunately Processors Desktops get the coresXe LP in 32 processing groups and mobile processors receive configurations of up to 96 processing groups.
We asked Intel people if we might see desktop processors with more powerful graphics cores in the future and we got an answer, and we were told that this architecture is very modular and a lot will be possible in the future. We hope that one day we will see a processor with a reduced amount of cores when on the other hand we can see the Xe HPG architecture for gaming in the same processor to create gaming computers that do not use a dedicated video card at all. We know well That competing processors do allow this today.
When it comes to connectivity protocols, Alder Lake takes a step forward in communication and memory standards. Processors Alder Lake will for the first time make use of the PCI-Express 5.0 standard, such an advanced standard that we have not yet met graphic cards Or means storage Households that use it. The desktop processors will allow 16 PCI-Express 5.0 lanes along with four more in the 4.0 XNUMX standard device storage Or other uses. The expected chipset of the system (Z690?) Will receive direct communication from the processor in the channel PCI-Express 4.0 X8.
Supported system memory is DDR4-3200 but also DDR5-4800. We can also meet the mobile processors with soldered memory next to them in LPDDR4x-4266 or LPDDR5-5200 standards. Of course these are the official operating frequencies supported but we are also expected to see significant significant fast memory support in practice. For example, Skylake processors came with support forDDR4-2133 but memory could be used from the beginning DDR4-2666 and later also much beyond that.
It is important for Intel to convey the message that the secret of Alder Lake lies in the totality of its components together, and that its value exceeds the value of the sum of its various parts. Processors These are produced in a procedure which is called Intel 7, was previously called the Enhanced 10nm SuperFin and will be available in chips in the heat envelope range of 9W to 125W.
Day Architecture of Intel Was replete with technical information and it was evident that Intel had worked hard on Alder Lake. Architecture Processors This does not reach an easy consumer market at all when both the desktop world and the mobile world have tough and uncompromising competitions in every direction. Intel has several fronts against high-resource competitors in every market share of its products.
The launch itself is expected in the last quarter of the current year for the various platforms. This means that we are likely to receive processors in November. Although there is a great deal of doubt surrounding this launch so far, it is important for us not to underestimate the "wait and see" value we received from the people Intel, When the results will later speak for themselves. On our questions about dealing with multi-core monsters that will come from the competition mostly people have shown Intel Confidence inAlder lake And a promise that the numbers will see the capability of technology.
Before concluding this summary on the Alder Lake architecture, we will note that when we asked the people Intel Regarding even more serious multi-core performance for rendering purposes we were told that "this is just the beginning" and that through the new bracket and new building blocks along with technologies we have not yet seen you will be able to Intel Significantly improve the performance of its laboratories in the later life of the new LGA1700 platform.
