Which one is better, I5 processor or Intel 4-core processor? Is there any difference?
1.I5 is Intel 4-core processor, the full name is Intel Core I5 ??processor (U and M numbers are dual-core)
2.Intel also has Core 4-core and Core I7 , Xeon 4-core, etc., there is no comparison like this.
The difference is that I5 is a 4-core intel processor, and an intel 4-core processor is not necessarily an I5. Is there any difference between an i5 processor and an i7 processor?
?7 920 generation Intel Core 2 series processor. Nehalem used to be the codename for the Pentium 4 10 GHz version. The name Core i7 has no special meaning. Intel said that the reason for choosing the name i7 is just to sound pleasant. Neither 'i' nor '7' has special meaning, nor does it refer to the 7th generation product. Core is the continuation of the success of the previous generation of Core processors. Some people will face the expensive Core i7 with the nickname "Beloved Wife". It is difficult for new architecture processors to enter the lives of consumers. However, it has been exposed recently. Another dual-core processor based on the Nehalem architecture, which still uses an integrated memory controller, a three-level cache mode, L3 up to 8MB, and a new processor that supports Turbo Boost and other technologies - Core i5 Core I5. Core i5 uses mature DMI (Direct Media Interface), which is equivalent to integrating all Northbridge functions internally. It uses DMI for quasi-Southbridge communication and only supports dual-channel DDR3 memory. What is the difference between I3 processors and I5 processors? , which one is better?
The high-end i5 is a quad-core
The i3 is a dual-core, four-thread, 32NM.
i5 is about 400 more expensive than i3. What is the difference between a 4-core processor and a 2-core processor?
A 4-core processor is faster than a 2-core processor. A core usually has only one thread that issues a single instruction and processes a set of tasks instantaneously. Multi-cores can handle multiple sets of tasks at the same time, dividing the pressure on other cores so they are faster.
The Central Processing Unit (CPU, Central Processing Unit) is a very large-scale integrated circuit and is the computing core (Core) and control core (Control Unit) of a computer. Its function is mainly to interpret computer instructions and process data in computer software.
The central processing unit mainly includes the arithmetic unit (arithmetic logic unit, ALU, Arithmetic Logic Unit) and the cache memory (Cache), as well as the bus that implements the data (Data), control and status between them. (Bus). It, together with internal memory (Memory) and input/output (I/O) devices, are collectively known as the three core components of electronic computers. What is the difference between i5 processor and i7 processor?
The main difference between I5 and I7:
Socket difference:
i5 is LGA 1156 pin, while i7 is LGA 1366. This is because i7 integrates a three-channel memory controller, which greatly increases the number of pins (contacts) of i7. After deleting one channel, i5 has 210 fewer pins than i7, but it is still much more than Core 2. Therefore, the i7 motherboard can accept 6 memory sticks, while the i5 can only accept 4 sticks. Since the SOCKETs of i5 and i7 are different, that is to say, these two CPUs will not be able to use the same motherboard.
Different memory controllers:
The enthusiast-grade LGA1366 interface Core i7 integrates a three-channel memory controller
The mid-to-high-end LGA1156 interface Core i5 integrates a dual-channel memory Controller and PCIE controller
The low-end LGA1156 interface Core i3 even has an integrated graphics card.
Different power consumption:
Compared with i7, i5 saves more power. This is because i5 integrates a simplified version of the Northbridge function, so there is no traditional Northbridge on the platform. The Northbridge has the largest power consumption on the motherboard, and the X58 Northbridge with 65nm process consumes a lot of power and generates heat. Compared with i7, i5 deletes one memory channel, so the number of memory controller transistors is drastically reduced. In addition, two less memories are plugged into the motherboard, which invisibly saves a lot of power consumption. More importantly, i5 uses the latest 45nm process, which is both 2.66GHz, but has a lower core voltage (i5 is about 0.1V lower than i7). The figure below shows the side view of power consumption.
PCI-E channels are different:
The memory controller of i5 has been shrunk, but it integrates more PCI-E controllers than i7, with 16+ PCI-E 2.0 Channel, it can provide up to one X16 or two X8 interfaces for the graphics card to use. The i7's supporting chipset, the Two-way, three-way, four-way SLI and CrossFire are dream platforms for game enthusiasts.
In addition, there is no difference between i5 and i7 processors. Their specifications are exactly the same as i7. In order to prevent i5 from threatening the status and price of i7, Intel has placed some restrictions on i5.
● Limitation 1: Lock NB frequency, memory performance is further limited
● Limitation 2: Lock QPI bus
*** between i5 and i7 Same point
i7 and i5’s unique TurboMode automatic overclocking technology
Turbo Mode, as the name suggests, is the acceleration mode. It is a power management technology based on the Nehalem architecture. By analyzing the current According to the CPU load condition, some unused cores are intelligently and completely shut down, leaving energy to the cores in use and making them run at a higher frequency to further improve performance; on the contrary, when multiple cores are needed, the corresponding ones are dynamically turned on. The core, intelligently adjusts the frequency. In this way, the core operating frequency can be adjusted higher.
Turbo Boost is enabled by default in the BIOS and improves performance by automatically increasing the CPU multiplier. For example, the default frequency of Core i7 920 is 20*133=2.66GHz. In the case of multi-tasking and heavy load, its frequency multiplier will automatically +1 to 21*133=2.8GHz; in the case of single thread, its frequency multiplier will be Automatic +2, reaching 22*133=2.93GHz.
● The automatic overclocking limit of Core i7 920: multiplier +1/+2
● The automatic overclocking limit of Core i5 XXX: multiplier +2/+4
It can be seen that the automatic overclocking range of i5 is larger than that of i7. The multiplier can be +4 in single-threaded applications and +2 in multi-threaded applications. In the future, if motherboard manufacturers can crack the i5 multiplier, the 22 multiplier will be Will make i5 better than i7!
Summary
It can be said that the high-end X58 platform is just a technology demonstration, while the mainstream P55 platform is the true form of bringing the nehalem architecture into people's homes. Even more exciting.
The main difference between desktop computers Core i5 and Core i7 is hyper-threading i5 four-core four-thread i7 four-core eight-thread, and the size of the third-level cache. The i5 is a third-level cache. 6M, i7 has a third-level cache of 8M. The overall performance of i7 is 30 to 35% better than i5, mainly in terms of hyper-threading, multi-tasking, multiple games, multiple software, etc., etc. The level 3 cache of 8M data is larger for i5. These are the biggest differences. What is the difference between Intel's i5 series processors and i7 series processors? Which processor is better?
The i5 and i7 processors of the same generation are mainly due to the addition of hyper-threading in the i7 processor. The performance is 15 to 20% better than the i5 of the same generation.
Processors of the same generation. The performance of i7 is definitely better. What is the difference between an 8-core processor and a 4-core processor?
If their architectures are the same,
The 8-core one is 2 times the processing speed of the 4-core one.
But in fact, 1.5 times is not bad.
But when it comes to games, the performance is not so good
When running a single game, 8-core has no advantage
When running multiple games, 8-core has an advantage AMD What is the difference between the processor of INTER and the processor of INTER?
The interface type pin is one of the devices connecting the CPU and the motherboard. Other interface methods include pin type, card type, contact type, pin type, etc. . The current CPU interfaces are all pin-type interfaces, which correspond to the corresponding slot types on the motherboard. Different types of CPU interfaces vary in the number of jacks, volume, and shape, so they cannot be plugged into each other. Pin type Socket 775 Socket 775, also known as Socket T, is the interface corresponding to the CPU currently used in the Intel LGA775 package. Currently, this interface is used in Pentium 4, Pentium 4 EE, Celeron D and other CPUs in the LGA775 package. Different from the previous Socket 478 interface CPU, the bottom of the Socket 775 interface CPU does not have traditional pins, but is replaced by 775 contacts, that is, not pin type but contact type, through the 775 in the corresponding Socket 775 slot. The contact pins transmit signals. The Socket 775 interface can not only effectively improve the signal strength of the processor and increase the processor frequency, but also improve the yield rate of processor production and reduce production costs. As Socket 478 gradually fades out, Socket 775 will become the standard interface for all Intel desktop CPUs in the future. Socket 754 Socket 754 is the CPU interface when AMD64-bit desktop platform was first released in September 2003. Currently, this interface is used by low-end Sempron and high-end Athlon 64, with 754 CPU pins. With the popularity of Socket 939, Socket 754 will eventually fade out. Socket 939 Socket 939 is a 64-bit desktop platform interface standard launched by AMD in June 2004. Currently, the high-end Athlon 64 and Athlon 64 FX using this interface have 939 CPU pins. Socket 939 processors cannot be mixed with the previous Socket 940 sockets. However, Socket 939 still uses the same CPU fan system mode, so the fans previously used for Socket 940 and Socket 754 can also be used in Socket 939 processors. device. Socket 940 1 Interface type 2 Pin type 2.1 Socket 775 2.2 Socket 754 2.3 Socket 939 2.4 Socket 940 2.5 Socket 603 2.6 Socket 604 2.7 Socket 478 2.8 Socket A 2.9 Socket 423 2.10 Socket 37 0 2.11 SLOT 1 2.12 SLOT 2 2.13 SLOT A 3 Number of pins Socket 940 is the earliest released AMD64-bit interface standard, with 940 CPU pins. Currently, this interface is used by Opteron and the original Athlon 64 FX used by servers/workstations. With the new Athlon 64 FX switching to the Socket 939 interface, Socket 940 will become Opteron's dedicated interface. Socket 603 Socket 603 is used more professionally and is used in Intel's high-end server/workstation platforms. The CPUs using this interface are Xeon MP and early Xeon, which have 603 CPU pins.
CPUs with Socket 603 interface are compatible with Socket 604 slots. Socket 604 Similar to Socket 603, Socket 604 is still used in Intel's high-end server/workstation platforms. The CPUs using this interface are Xeon with 533MHz and 800MHz FSB. CPUs with Socket 604 interface are not compatible with Socket 603 slots. Socket 478 The Socket 478 interface is the interface type currently used by the Pentium 4 series processors, with a pin count of 478. The Socket 478 Pentium 4 processor is very small and its pin arrangement is extremely compact. Intel's Pentium 4 series and P4 Celeron series both use this interface. Socket A The Socket A interface, also called Socket 462, is the current socket interface for AMD's Athlon XP and Duron processors. The Socket A interface has 462 slots and can support 133MHz FSB. Socket 423 The Socket 423 socket is the standard interface of the original Pentium 4 processor. The appearance of Socket 423 is similar to the previous Socket type sockets, and the corresponding CPU pin number is 423. Socket 423 slots are mostly based on Intel 850 chipset motherboards and support Pentium 4 processors from 1.3GHz to 1.8GHz. However, with the popularity of DDR memory, Intel developed the i845 chipset that supports SDRAM and DDR memory. The CPU socket was also changed to Socket 478, and the Socket 423 interface disappeared. Socket 370 Socket 370 architecture was developed by Intel to replace the SLOT architecture. It looks very similar to Socket 7. It also uses a zero-plug force slot and the corresponding CPU is 370 pins. Intel's famous "Copper Mine" and "Tualatin" series of CPUs use this interface. SLOT 1 SLOT 1 is a CPU interface developed and patented by Intel to replace Socket 7. In this way, other manufacturers will not be able to produce products with SLOT 1 interface. The CPU with the SLOT1 interface is no longer the familiar square shape, but has become a flat rectangular parallelepiped, and the interface has also become a golden finger instead of a pin. SLOT 1 is a slot designed by Intel for the Pentium II series CPU. It integrates the Pentium II CPU, its related control circuits, and the second-level cache on a daughter card. Most Slot 1 motherboards use 100MHz FSB. The technical structure of SLOT 1 is relatively advanced and can provide greater internal transmission bandwidth and CPU performance. This type of interface has been eliminated, and there are no products with this type of interface on the market. SLOT 2 SLOT 2 is more professional and is used in high-end servers and graphics workstation systems. The CPU used is also very expensive Xeon series. Slot 2 has many differences from Slot 1. First of all, Slot 2 is longer and the CPU itself is larger. Secondly, Slot 2 is capable of higher-demand multi-purpose computing processing, which is the key to entering the high-end enterprise computing market. In the standard server design at the time, general manufacturers could only use two Pentium II processors in the system at the same time. With the Slot 2 design, 8 processors could be used in one server at the same time. Moreover, the Pentium II CPU using the Slot 2 interface adopted the most advanced 0.25 micron manufacturing process at the time. Motherboard chipsets that support the SLOT 2 interface are 440GX and 450NX. SLOT A The SLOT A interface is similar to Intel's SLOT 1 interface, used by AMD's K7 Athlon. In terms of technology and performance, SLOT A motherboard is fully compatible with various original peripheral expansion card devices. It does not use Intel's P6 GTL+ bus protocol, but Digital's Alpha bus protocol EV6.
The EV6 architecture is a more advanced architecture that uses a multi-threaded point-to-point topology and supports a bus frequency of 200MHz. Number of Pins Currently, CPUs use pin-type interfaces to connect to the motherboard, and CPUs with different interfaces have different numbers of pins. The naming of CPU interface types is usually expressed by the number of pins. For example, the Socket 478 interface currently used by the Pentium 4 series processors has 478 pins; while the Socket 462 interface used by the Athlon XP series processors has 478 pins. The number is 462 stitches.
