Intel dual core mobile processor: Intel Pentium Dual Core Processor

Difference Between Core Solo & Core Duo Intel Processor | Small Business

By Dan Wonder

The Core Solo and Core Duo were the first central processing units released under Intel Corp’s Core brand, which would displace Pentium as the company’s premier line of processors for personal computers. The semiconductor giant differentiated the CPUs according to number of processing units: the Core Solo is a single-core chip, while the Core Duo is a dual-core chip. Intel produced seven Core Solo and 15 Core Duo processors.

Nomenclature

The Core Solo and Core Duo are split into categories, depending on their energy efficiency and number of cores. The ones with standard power comprise the “T” series, and those with ultra-low power consumption are collectively called the “U” series. The Core Duo has a third designation, “L,” for the middling low-power chips. With the Core Solo, each CPU’s name consists of the one-letter prefix, the number “1” for the single processing unit on the chip, and two additional digits. The Core Duo uses “2” instead, signifying its two processing units. As a dual-core CPU, the Core Duo has twice the amount of processing power as the Core Solo.

Speed and Motherboard

Clock or processing speed on the Core Solo ranges from 1.06GHz on the U1300 to 1.86GHz on the T1350. The slowest Core Duo, the U2400, matches the processing speed of the U1300. However, the fastest Core Duo, which is the T2700, surpasses the T1350 with 2.33GHz. An interface called the front-side bus connects the CPU to the components of the computer’s motherboard at a speed of 533MHz or 667MHz. Each processor is fitted on the motherboard with one of two CPU sockets called Socket M and BGA479.

Cache and Power

The Core Solo and Core Duo has two levels of cache, with the L2 cache providing 2MB of storage space for fast data access. Peak power consumption on the Core Solo is 5.5 watts on the U1500 to 31 watts on the T1250. The Core Duo is generally a less power-conserving processor. At 9 watts, the U2400 and U2500 are the most energy-efficient Core Duo chips. Ten of the Core Duo processors consume as much power as the Core Solo T1250.

Current Status

Intel began phasing them out in 2007 and they are now discontinued. At the time, the company was shifting towards using the 45nm lithographic node to manufacture smaller CPUs; the Solo and Duo were 65nm processors.

What Do «Dual Core» and «Quad Core» Mean?

When purchasing a new laptop or building a computer, the processor is the most important decision. But there’s a lot of jargon, especially the cores. For example, do you need a dual-core processor, a quad-core, a hexacore, an octa-core, or more?

Let’s cut the jargon and understand what it all really means.

Dual-Core vs. Quad-Core, Explained

Here’s everything you need to know:

There is always only one processor chip. That chip can have one, two, four, six, eight, ten, twelve, or even sixteen cores. So if you find a «single core» CPU, that means the processor chip has one core. And a dual-core processor has two cores, a quad-core has four, a hexa-core has six, an octa-core has eight, and so on.
Currently, an 18-core processor is the best you can get in consumer PCs. I mean, you could buy a 64-core AMD Threadripper, which is available to consumers, but that’s more processing power than most regular consumers could think of using.
Each «core» is the part of the chip that does the processing work. Essentially, each core is a central processing unit (CPU).

This article deals with dual-core vs. quad-core processors for computers, not for smartphones. We have a separate post on understanding smartphone cores.

The Difference Between Dual-Core and Quad-Core CPUs

You might think more cores will make your processor faster overall, but that’s not always the case. It’s a little more complicated than that.

More cores are faster only if a program can split its tasks between the cores. Not all programs are developed to split tasks between cores. More on this later.

Each core’s clock speed is also a crucial factor in speed, as is the architecture. A newer dual-core CPU with a higher clock speed will often outperform an older quad-core CPU with a lower clock speed.

Power Consumption

More cores also lead to higher power consumption by the processor. When the processor is switched on, it supplies power to all the cores, not just one at a time.

Chip makers have been trying to reduce power consumption and make processors more energy efficient. But as a general rule of thumb, a quad-core processor will draw more power from your laptop (and thus make it run out of battery faster).

More Cores Equal More Heat

More factors than the core affect the heat generated by a processor. But again, as a general rule, more cores lead to more heat.

Due to this additional heat, manufacturers need to add better heat sinks or other cooling solutions.

Are Quad-Core CPUs More Expensive Than Dual-Core?

More cores isn’t always a higher price. Like we said earlier, clock speed, architecture versions, and other considerations come into play.

But if all other factors are the same, then more cores will fetch a higher price.

Software Optimization for CPU Cores

Here’s the dirty little secret that chip manufacturers don’t want you to know. It’s not always about how many cores you are running; it’s about what software you are running on them.

Programs have to be specifically developed to take advantage of multiple processors. In the past, «multi-threaded software» wasn’t as common, although as it’s near-impossible to buy a single-core CPU these days, this issue isn’t once what it was.

However, it’s important to note that even if it’s a multi-threaded program, it’s also about what it is used for. For example, the Google Chrome web browser supports multiple processes, as does video editing software Adobe Premiere Pro.

Adobe Premiere Pro instructs different cores to work on different aspects of your edit. Considering the many layers involved in video editing, this makes sense, as each core can work on a separate task.

Similarly, Google Chrome instructs different cores to work on different tabs. But herein lies the problem. Once you open a web page in a tab, it is usually static after that. There is no further processing work needed; the rest of the work is about storing the page in the RAM. This means even though the core can be used for a background tab, it is unnecessary.

This Google Chrome example is an illustration of how even multi-threaded software might not give you much of a real-world performance boost.

Double the Cores Is Not Double the Speed

So let’s say you have the right software and all your other hardware is the same. Would a quad-core processor then be twice as fast as a dual-core processor? Nope.

Increasing cores does not address the software problem of scaling. Scaling to cores is the theoretical ability of any software to assign the right tasks to the right cores, so each core is computing at its optimal speed. That’s not what happens in reality. In reality, tasks are split sequentially (which most multi-threaded software does) or randomly.

For example, let’s say you have a quad-core processor (Core1, Core2, Core3, Core4). You need to accomplish three tasks (T1, T2, T3) to finish an action, and you have five actions (A1, A2, A3, A4, A5) like this.

Here’s how the software will divide tasks:

Core1 = A1T1
Core2 = A1T2
Core3 = A1T3
Core4 = A2T1

The software is not smart, though. If A1T3 is the hardest and longest task, the software should have split A1T3 between Core3 and Core4. But now, even after Core1 and Core2 finish their tasks, they have to wait for the slower Core3’s task to complete the action.

All of this is a roundabout way of saying that not all software is optimized to take full advantage of multiple cores. And doubling the cores does not always equal doubling the speeds.

Where Do More Cores Really Help?

Now that you know what cores do and their restrictions in boosting performance, you must be asking yourself, «Do I need more cores?» Well, it depends on what you plan to do with them.

Dual-Core and Quad-Core in Gaming

If you fancy yourself to be a gamer, then get more cores on a gaming PC. The vast majority of new AAA titles (i.e., popular games from big studios) support multi-threaded architecture. Video games are still largely dependent on the graphics card to look good, but a multi-core processor helps too.

Editing Videos or Audio

For any professional who works with video or audio programs, more cores will be beneficial. Most of the popular audio and video editing tools take advantage of multi-threaded processing.

Photoshop and Design

If you’re a designer, a higher clock speed and more processor cache will increase speeds better than more cores. Even the most popular design software, Adobe Photoshop, largely supports single-threaded or lightly threaded processes. Multiple cores aren’t going to be a significant boost with this.

Should You Get More Cores?

Overall, a quad-core processor is going to perform faster than a dual-core processor for general computing. Each program you open will work on its own core, so if the tasks are shared, the speeds are better. If you use a lot of programs simultaneously, switch between them often, and assign them their own tasks, then get a processor with more cores.

Just know this: overall system performance is one area where far too many factors come into play. Don’t expect a magical boost by changing one component like the processor. Choose wisely and buy the right processor for your needs.

The 12th Gen Core mobile processors based on the Intel 7 process technology are based on a hybrid architecture that combines high-performance and power-efficient cores in a single chip. According to Intel, the performance advantage of new products over their predecessors reaches 40%. The senior processor among the presented mobile novelties was the Core i9-12900HK — Intel calls it the fastest mobile processor of our time and the best CPU for gaming laptops.

The H-series includes processors up to 5.0 GHz with up to 14 cores (6 powerful Golden Cove and 8 energy efficient Gracemont) and supporting up to 20 threads. In general, various models of H-series processors can have 4 or 6 performance cores and 4 or 8 energy efficient cores. The composition of the model range is shown in the table below.

The base heat dissipation of all the listed processors is stated at 45 W, but laptop manufacturers will be able to vary this value in their designs.

Based on Intel benchmarks, the flagship Core i9-12900HK mobile processor outperforms the Core i9-11980HK in gaming performance by a hefty 28% (when used in a gaming laptop with GeForce RTX 3080 mobile graphics). And its superiority over the Ryzen 9 5900HX is even more convincing.

In addition, the Core i9-12900HK boasts high performance when working with digital content. For example, its advantage over the Core i9-11980HK in rendering reaches 43%.

The new mobile platform accompanying the 12th Gen Core processors supports four types of DDR5/LPDDR5 and DDR4/LPDDR4 memory with a maximum module frequency of 4800 MHz. The platform also supports Wi-Fi 6E and Thunderbolt 4 interface with a bandwidth of up to 40 Gb / s.

The first laptops based on 12th generation Core H-series processors will be available in February 2022. Over 100 different devices are expected to be released from leading manufacturers including Acer, Asus, Dell, HP, Lenovo, MSI and Razer.

Intel also announced that other 12th Gen Core mobile processor series designed for thin and light laptops will hit the market later in the first quarter. We are talking about the P-series (with a thermal package of 28 W) and the U-series (with a thermal package from 9 to 15 W). The range of these new products is already known — older models in the P series, like the Core i9-12900HK, will be able to offer up to 14 cores and 20 threads along with integrated Iris Xe graphics. And the maximum models of the U-series will receive two productive and eight energy-efficient cores.

Based on these energy-efficient Alder Lakes, Intel partners are preparing a wide range of devices, including transformers, 2-in-1 laptops, laptops with flexible screens, and more. The devices will ship with both Windows and Chrome OS operating systems.

Use Google search

26.02.2013

At MWC 2013, the world’s leading processor manufacturer presented its new mobile chips designed for use in smartphones and tablets.

. CES 2013, but at the time all Intel could tell us was that their new chips would have twice the performance of Medfield processors.

We have now learned that the Intel Clover Trail+ system-on-a-chip (SoC) family will include at least three models operating at frequencies from 1.2 to 2.0 GHz.

All three chips will feature PowerVR SGX 544 GPUs, which should give them slightly better imaging performance than the Medfield chips, although it remains to be seen how they will compete with the latest ARM processors from Qualcomm, NVIDIA and Samsung.

Here is the list of representatives of the new Intel Clover Trail + family:

Intel Atom Z2520 — Dinelled Processor 1. 2 GHC

Intel ATOM Z2560 — DISURED processor 9000 9000 9000. — 2GHz dual-core processor

Intel says each chip will be able to display 3D on screens up to 1920 x 1200 pixels and support up to 2GB of RAM.

The company’s new processors can be used to create smartphones and tablets with the Android operating system and have built-in support for HDMI video output, and HDR cameras with matrices with a maximum resolution of up to 16 megapixels.
