Is the I3 dual core fast or the AMD quad core fast

Actually, it's not very accurate for the landlord to say this.

The i3 series also has a lot of CPUs

AMD quad-core is even more numerous.

Take the current mainstream i3 2100 and AMD X4 640 for example.

If it is more advantageous than the single-threaded performance of the i3 (PS and some games before 09), but the i3 is a dual-core after all, and the four-threaded CPU is not pure, so in some new games (which support four-thread), and some working software, rendering, cartography, compression, decoding, etc., AMD quad-core has an absolute advantage.

At present, i3's ** is a little more expensive, so in terms of cost performance, AMD X4 640 is cost-effective.

And the i3 2100 can't be overclocked (it's almost impossible to overclock, because that's not overclocking), while the x4 640 some batches can be turned on and can be overclocked.

I've experienced it myself, don't say i3, even i5 high configuration, play games, performance is not as good as a dual-core amd, just add a 1g independent display, i5 play games processing is directly game stuck, and then don't like amd to deal with the game intact, garbage i5 used to play games, my monitor has been smashed by me3, and then changed to a 970 motherboard and cpu all game troubles have been solved, and then i threw i5 to a bridge in nanning, i can only say that i5 is still good to watch movies live, Playing games is a garbage disposer.

It's not that more cores are better, a task can't be completed with multiple cores, and there are few online games that are optimized with 4 cores.

It depends on whether you play online or standalone.

i3 single-tasking processing ability is much faster than AMD640, 640 multitasking ability is stronger than i3, in terms of games, online game i3 is much faster than AMD640, because online games support dual-core, playing stand-alone games that support four-core 640 is much stronger than i3.

The whole process of the i3 processor is called the "Core i3 processor", which is a processor of Intel Corporation. A dual-core processor means that this processor has 2 cores.

Some models of the Core i3 processor are dual-core and four-threaded, and some are four-core and four-threaded. Therefore, it can be said that the "dual-core processor" is not a certain model of processor. However, the "dual-core processor" that everyone usually refers to Intel's Celeron dual-core processor or Pentium dual-core processor.

The differences and performance are as follows:

Pentium dual-core, Celeron dual-core, is a relatively low-end processor, generally dual-core and dual-threaded, can only meet the needs of surfing, office, and watching movies;

Core i3, is a mid-range processor, which can be understood as a lite version of the Core i5, with some models with dual cores and four threads, and some with four cores and four threads. In addition to surfing the Internet, office, and watching movies, you can play online games or large-scale stand-alone games;

i3 is a processor model, and if it is dual-core, it is the number of cores of the processor, and they are completely different concepts.

The dual-core you are referring to should be the general Core 2 dual-core, the difference is that the technology made by i3 is better, faster, and the others are not.

i3 is a kind of dual-core, not a matter of difference, it is a question of category, dual-core is a big classification of processor models, i3 is a small category of dual-core.

First of all, it's all CPUs. And then... You say to a CPU:

This is dual-core, and it's like saying to a car: this is a BMW and you say to a CPU: i3 is like saying to a car

This is the BMW 3 Series... That's how it is understood.

The Core i3 is a dual-core processor and does not have a quad-core one.

The Core i3 is a CPU family logo for mainstream users. There are a number of sub-collections such as Clarkdale (2010), Arrandale (2010), Sandy Bridge (2011), Ivy Bridge (2012) and Haswell (2013).

Core i3 will be encapsulated by two cores: CPU + GPU.

A dual core processor is one that integrates two computing cores on a single processor to increase computing power.

The concept of "dual-core" was first proposed by high-end server manufacturers such as IBM, HP, SUN and other high-end server manufacturers that support RISC architecture, but due to the high quality of RISC architecture servers and narrow application areas, it has not attracted widespread attention. Put simply, a dual-core processor is a processor based on a single semiconductor that has two cores with the same functionality. In other words, two physical processor cores are combined into a single core.

Chipmakers have also been looking for ways to improve performance without increasing the actual hardware footprint. Multi-core processor solutions address these needs, delivering enhanced performance without the need for more power or physical space.

i3 does not have a physical quad-core, desktop terminal CPUI3 is dual-core, and the specification of notebook terminal CPUI3 is lower; The desktop terminal i5 is a quad-core quad-thread, which is the real physical quad-core, while the notebook i5 depends on the specifications, some are dual-core quad-threads and some are quad-core quad-threads.

In your case, a typical i3 dual-core four-thread, how can you believe that the installer is talking nonsense to you? Hardware is what you pay for, and if the i3 is quad-core, then why sell it cheaper than the i5?

Put your mind at ease and use your machine with peace of mind, there is no need to worry about it. You paid for the i3 performance and that's ok. It's just that you were fooled by the person who installed the machine, and you feel uncomfortable.

If you bought the i5 for the i3, that's a problem, but that's obviously not the case now.

In addition, it is worth mentioning that although the i5 is indeed stronger than the i3, the i3 is definitely enough, and there is no need to dwell on the number of cores.

The i3 is just dual-core, hyper-threading is two more virtual cores, not actually dual-core, hyper-threading just improves performance.

There are no quad-cores below the i5 series, and they are all dual-core and four-threaded.

There is no such thing as a virtual quad-core, misleading.

The eighth-generation i3 has four cores and four threads.

That's right.

Intel CPU performance has always been stronger than that of its peers.

Intel has always been more expensive than AMD, otherwise AMD would not have survived.

In addition to hyper-threading, i3 also has a core graphics, which can replace the previous integrated graphics.

Yes, the i3 only has a dual-core quad-thread.

Dual-core: Simply put, it is 2 cores, and the core, also known as the core, is the most important component of the CPU.

The bulging chip in the center of the CPU is the core, which is manufactured by monocrystalline silicon with a certain production process, and all the calculations, storage commands, and data processing of the CPU are executed by the core.

Hyper-Threading Technology: Hyper-Threading technology is used when there are two cores in the processor, and one core has 2 threads.

With hyper-threading technology, there are 4 threads in two cores.

The number of CPUs seen in the operating system is twice as large as the actual number of physical CPUs, that is, 1 CPU can see two, and two can see four.

If the processor has four cores and does not support hyper-threading (e.g. Core i5), it will only have four threads, and the display will be the same as that of dual-core four-wire, but the performance will be higher than that of dual-core four-wire.

Don't look down on hyper-threading technology! Compared with 641, the performance of 2120 is higher at the default frequency, because different execution efficiency, different architecture, process, etc. determine its performance.

With hyper-threading, applications can use different parts of the chip at the same time. While a single-threaded chip can process thousands of instructions per second, it can only operate on one instruction at any one time. The hyper-threading technology can enable the chip to be multi-threaded at the same time, so that the chip performance can be improved.

Personally, I think it will be easier for Intel to improve CPU performance, after all, desktop computers are now eight-core, and Tel can achieve 16-core performance if he joins hyper-threading, and AMD is not generally small to make a 16-core CPU, but they are each good and are developing in their own direction.

Hyper-threading is a controversial technology, whether there is a performance improvement or not, no one has the ability to test and confirm, the overall performance of a processor is not only by the core and frequency can be performed, there are many technical indicators, process indicators, etc. to calculate the actual performance, there is also brand value, word of mouth value in it. So there is a reason why 4-core and 4-core, dual-core 4-core, etc. will be different**.

The performance of the first and second generation i3 is indeed better than that of the first and second generation of Athlon, 4 cores, plus the i3 is higher than the brand positioning of Athlon, (Intel products are actually in the middle and high-end crowd, and AMD is in the middle and upper end of the group, only server processors and GPU high-end) There are many reasons.
