CPU computing power Intel

1. The computing power of CPU is related to the number of CPU cores, the frequency of core and the ability of single clock cycle of core
the ability of double precision floating-point computing is commonly used to measure the scientific computing ability of CPU, that is, the ability to process 64 bit floating-point data

the processor supporting avx2 can perform 16 floating-point operations in one core and one clock cycle, Also known as 16flops
CPU power = number of cores x frequency of cores x 16flops
processors supporting avx512 can perform 32 floating-point operations in one core and one clock cycle, also known as 32flops
CPU power = number of cores x frequency of cores x 32flops

2. I54590 is a four core, four thread, three-level cache is 6MB. The i7 4790 is a 4-core 8-thread, 3-level cache of 8MB. CPU is not only determined by the dominant frequency.

3. Only Intel and AMD, NVIDIA IBM, Intel AMD and many other servers, the best IBM, Intel
for home use, Intel and AMD, CPU computing power, how many calculations per second

4. No, CPU Intel means that this CPU is proced by Intel
intel core is the core Series CPU in Intel CPU. In addition to the core series, there are Pentium, Celeron and Xeon

6. The number of pins depends on the interface of CPU
socket 939
socket 939 interface is the interface type adopted by AMD Athlon 64 and AMD Athlon 64 x2 series processors, with 939 pins

socket 754
socket 754 interface is the interface type adopted by AMD Sempron flash dragon series processors, with 754pin pins

Socket 775
Socket 775 is an interface type adopted by Pentium D and core 2 Duo series processors, with 775Pin pins. The symbol of the al core era

socket 478
socket 478 interface is the interface type adopted by Pentium 4 series processor, with 478 pins. The Pentium 4 processor of socket 478 has a small area, and its pins are closely arranged. Intel's Pentium 4 series and P4 Celeron series use this interface< Socket AM2 interface, also known as socket 940, is the socket interface of Athlon 64 AM2 processor of AMD company. Socket AM2
interface has 940 slots and can support 200MHz external frequency

socket a
socket a interface, also known as socket 462, is the socket interface of Athlon XP and Duron processors of AMD company. Socket a interface has 462 slots and can support 133MHz external frequency

socket 423
socket 423 is the standard interface of the original Pentium 4 processor. The appearance of socket 423 is similar to that of the previous socket classes, and the corresponding number of CPU pins is 423. Socket 423 slots are mostly based on Intel 850 chipset motherboard and support 1.3ghz-1.8ghz Pentium 4 processor. However, with the popularity of DDR memory, Intel has developed i845 chipset which supports SDRAM and DDR memory. The CPU slot has been changed to socket 478, and the socket 423 interface has disappeared<

socket 370
socket 370 architecture is developed by Intel to replace slot architecture. It is very similar to socket 7 in appearance, and it also adopts zero plug force slot. The corresponding CPU is 370 pins. Intel's famous copper and tuladin series CPUs use this interface<

slot 1
slot 1 is a CPU interface developed by Intel to replace socket 7, and has applied for a patent. In this way, other manufacturers cannot proce procts with slot 1 interface. The CPU of slot1 interface is no longer the familiar square appearance, but has become a flat cuboid, and the interface has also become a golden finger, no longer a pin form
slot 1 is a slot designed by Intel company for Pentium II Series CPU. It makes Pentium II CPU and its related control circuit and secondary cache on one sub card. Most slot 1 motherboards use 100MHz external frequency. The technical structure of slot 1 is relatively advanced, which can provide more internal transmission bandwidth and CPU performance. This kind of interface has been eliminated, and there are no such interface procts on the market

slot 2
the purpose of slot 2 is more professional, which is used in high-end server and graphics workstation system. The CPU used is also very expensive Xeon series. There are many differences between slot 2 and slot 1. First of all, slot 2 slot is longer and CPU itself is larger. Secondly, slot 2 is capable of multi-purpose computing with higher requirements, which is the key to enter the high-end enterprise computing market. In the standard server design at that time, most manufacturers could only use two Pentium II processors in the system at the same time. With the slot 2 design, they could use eight processors in one server at the same time. Moreover, the Pentium II CPU with slot 2 interface adopted the most advanced 0.25 micron manufacturing process at that time. There are 440gx and 450nx motherboard chipsets supporting slot 2 interface

slot a
slot a interface is similar to Intel's slot 1 interface, which is used by AMD's K7 Athlon. In terms of technology and performance, slot a motherboard is fully compatible with all kinds of original peripheral expansion card devices. It does not use Intel's P6 GTL + bus protocol, but digital's alpha bus protocol EV6. EV6 architecture is a kind of advanced architecture, which adopts the point-to-point topology of multithreading and supports the bus frequency of 200MHz.

I and the number after it are fixed collocation address, just a name< br />

8. If you buy more than 1000 yuan CPU, Intel
has strong performance
the overall performance is better than AMD's
AMD's advantage lies in its high cost performance and integrated platform

9. Qualcomm's mobile CPU is better
Intel's computer CPU is better
compared with its computing power, Intel's CPU is hundreds or thousands of times higher than that of Qualcomm's (single CPU). In particular, Xeon financial core and Xeon computing card are banned from China in the United States
tianhe-2 supercomputer used the Xeon e5v2 + old Intel Xeon accelerator card at that time, and won the first supercomputer in the world that year (therefore, it was banned in the United States)

10.

CPU Iji refers to a series of CPU of Intel Corporation. Iji refers to different models in the series, such as I3, i5, i7, etc

the core processor adopts the front-end bus speed of 800mhz-1333mhz, and the al core core processor shares 12ml2 resources through SmartCache technology

following the "Pentium" processor which has been used for 12 years, Intel launched the "core 2 Duo" and "core 2 Quad" brands, as well as the latest Core i7, core i5 and core I3 CPUs

Core i7

processor is a 64 bit four core CPU launched by Intel in 2008, which uses i7 920 x86-64 instruction set and is based on Intel Nehalem micro architecture. I7 920 replaces Intel Core 2 series processor

Nehalem used to be the code name of Pentium 4 10 GHz version. The name of Core i7 has no special meaning. Intel says that the reason for choosing the name is that it sounds pleasant; i' And 39; 7' There is no special meaning, not to mention the seventh generation of procts

core i5

facing the expensive Core i7, the new architecture processor is difficult to enter the life of the majority of consumers. However, another four core processor based on Nehalem architecture is exposed, which still adopts integrated memory controller, three-level cache mode, L3 reaches 8MB, and supports turbo boost and other technologies core i5, namely core i5

core I3

core I3 can be regarded as a further simplified version of core i5, and the latest 32nm process version (R & D Code: Clarkdale, based on Westmere Architecture) will be adopted. The biggest feature of core I3 is the integration of GPU (graphics processor), that is to say, core I3 will be packaged by CPU + GPU

e to the limited performance of the integrated GPU, users can add a graphics card if they want to get better 3D performance. It is worth noting that even for Clarkdale, the manufacturing process of the display core will still be 45nm

the plan of integrating CPU and GPU has been put forward for a long time by Intel and AMD. They all think that integrating platform is a trend in the future. Intel is no doubt in the lead. The CPU integrated with GPU has been launched, named core I3
