| Line 1 printed on processor represents the brand name, manufacturing year and the processor name.Line 2 depicts the complete name of the processor.Line 3 is the SSPEC number (specification number) and the plant name.Line 4 comprises of the clock speed/L3 cache size/bus speed/PCG marking (for power requirements) in that order. | Line 5 tells the batch code of the processor. You can decipher the batch code as follows: 1st character: plant code2nd character: year of production3rd & 4th characters: week number5th to 8th characters: lot number |
Core i7
Variants are available under codenames Bloomfield and Lynnfield for desktops and Clarksfield and Arrandale for laptops. They constitute a series of quad core (45 nm) microprocessors with different versions, all having 8 MB of level 3 cache which Intel calls the Smart Cache. They use the Intel Virtualization technology and 3 Channels of DDR3 1066 MHz memory to boost performance.
Intel launched the Core i7 Extreme edition for users who need to run high-end applications like extreme games and real time business analytics applications. Due to the combination of Turbo Boost and Hyper-Threading technologies, the processors deliver improved performance in multitasking, digital media creation, video encoding and image rendering.
Core i5
Working on the same architecture as the Core i7, the Core i5 processors is able to deliver a better performance to price ratio. The Core i5 750 is targeted at a larger user base, which consists of regular workgroup users who need a robust processor with better power consumption and good performance. The processor is also billed to be of great use in multitasking for multimedia applications.
Core i3
Intel plans to launch the Core i3 series in the form of Core i3 530 (2.93 GHz) and the Core i3 540 (3.06 GHz) with support for 4MB Cache. These specifications place Core i3 as an entry level processor in the Core i family. With the core i3 processors, Intel takes a step forward in the 32nm fabrication process which might be their area of operation in the future as well. Core i3 is targeted at users who want reliable processing at an affordable budget.
Core i9The last processor in the Nehalem-based Core processor lineup will be the Core i9 brand expected to be launched in the second half of 2010. With 32 nm six Gulftown cores inside, and the same socket as in Bloomfield, Core i9 can essentially be seen as an upgrade to the Core i7 9xx series.
