Intel i3 Vs Intel i5 Vs Intel i7 By, Aravind Alluri.
Intel i3 Vs Intel i5 Vs Intel i7 Introduction. Intel Core i3 Intel Core i5 Intel Core i7 Comparison among i3, i5 and i7. Conclusion.
Westmere Its Intel’s code-name for Core i3 and Core i5 6xx processors. Its 3rd generation of Intel’s Nehalem architecture.Major differences : It’s built on 32nm manufacturing processor. Advantage : Lower power consumption and Reduced size.
Westmere (cont..) Itincludes SSE (Streaming SIMD Extensions) instructions aimed at accelerating encryption and decryption with the AES algorithm. Westmere is largely the same as previous Nehalem processors with slight variations.
The IGP : Clarkdale Intelhas IGP onto the same die as the CPU. They are still separate entities, but they are kept on the same piece of hardware. This combination results are not so exciting as they sound. Real advancement is the inclusion of support for Dolby True HD and DTS HD- MA bit streaming over HDMI.
The IGP : Clarkdale(cont..) Due to that, Core i3 based system could play any kind of movie you throw at it, including Blu-Rays, without performance issues and without running into problems with Blu-Ray encryption.
Intel Core i3 Codenamed: Clarkdale (Westmere) Fabrication: 32 nm Instruction set: X86, X86-64, MMX, SSE 4.2 Socket: LGA 1156 Bus: Direct Media Interface replacing FSB( Front Side Bus) RAM: DDR3 Chipset Support: P55, H55, H57, Q57
Intel Core i3 (cont..) Clock speeds : 2.93 to 3.06 GHz. Cache : 2X256 KB L2 and 4MB L3 . Supports Hyper Threading Has an Integrated graphics processor. These don’t support Turbo Boost (Dynamic over-clocking).
Hyper Threading It is a technology used by Intel to simulate more cores than actually exist on the processor. It also improves performance when using programs that make good use of multi- threading.
Dual Core i5 (cont..) Clock Speeds : 3.2 to 3.6 GHz. Cache : 2x256 KB L2 and 4MB L3 Has Integrated Graphics Processor Include Turbo Boost. Supports Hyper Threading.
Quad Core i5 Architecture : Lynnfield (Nehalem) Fabrication : 45nm Socket : LGA 1156 BUS : DMI Two Processors with Clock Speeds of 2.4 and 2.66 GHz. Cache : 4x256 KB L2 and 8MB L3 Supports Turbo Boost. Don’t support Hyper Threading and have No Integrated Graphics Processor.
Intel Core i7 (cont..) They offer the Best Performance. Cache : 4x256 KB L2 and 8MB L3 They support Turbo Boost and Hyper Threading(8 virtual cores) Don’t have an Integrated Graphics Processor.
Core i3 Vs Core i5 Vs Core i7 (cont..) Performance : Besides being multi-core, Hyper Threading technology combined with the Turbo Boost makes i3, i5 and i7 to be computing power houses. For gaming, core i7 processors win hands due to their phenomenal processing power. Even Core i5’s are good enough but if you want raw power then its good to go for i7. Core i7 is much faster due to the QPI , Hyper Threading and Turbo Boost. Cost : Core i3 are priced at $133 only while Core i5 are priced at $176 to $256 and Core i7 are priced in the range $200 to $1000.
Which is better for whom? If you are into an entry level system its good to go for core i3 line. It’s great for home use desktop computers too. Core i5 line is ideal for the business user or home users, who are into normal gaming. If you want your system to be almost like a server with super computing power at your finger tips go for i7 (Best processor yet on the earth). Note : Choose that suits your budget and computing requirements.
Conclusion Intel core i3, i5 and core i7 are the best series of processors yet in the present market. Intel core i7 is the Best processor ever on the earth as of now. Intel sustains its value and dominated the market coming up with this successful series of Core i3, Core i5 and Core i7.
