The CPU is fastest processing component in our computer. Though the other peripheral devices(RAM, Hard disk, CD Drive, etc) are very slow as comparative to CPU. These devices takes too much time to understand and use the data send by CPU. while CPU is working with its very high speed.
Because of such condition there are very high chances that Other peripherals or IO devices get flooded by data sent by CPU like bottleneck situation.
To Avoid this situation CPU maintains three cache lines, L1, L2, and L3. with positions as within CPU(L1), at boundary of CPU(L2) and Just Outside of CPU(L3).
therefore the meaning of a processor with 3 MB L3 cache mean cache line 3 can store up to 3 MB data/ addresses, to work with slow IO devices.

cache memory it com up with processor p4 and more with max 2 mb it is of 3 the L1 L2 L3:- L1 AND L2 are in processr and L3 is in mother bord Shorter version: It increases memory space in the CPU.
4 MB
This "3MB" is probably proceeded by "L2 cache" or "L3 cache" Or, its 3GHz. If it is 3MB, then it is referring to the instruction-caching memory that is built right into the processor, a few small panels of extremely fast memory that temporarily store instructions for the processor. The including of cache greatly increased a processors overall performance. The L2 and L3 portion refer to levels of cache. L1 Cache is very small, typically two blocks of 32KB or 64Kb. This Cache is the fastest, used for branch prediction and direct instruction strings. L2 Cache is larger, typically 1MB or 2MB, and also a fair deal slower than L1 cache. L3 Cache is the slowest, and is shared by multiple cores (If there is more than 1) and is the largest cache, typically 3MB - 16MB, depending on the processor. If it is actually 3GHz, then this is the number that reflects the number of Cycles Per Second, or Hertz, that the processor is capable of. 3Ghz is Three Giga-Hertz, or 3,000,000,000 Cycles per Second. Amazing isn't it?
yes i have dell gx280 3.0 gh with 2 mb cache
3 mb
The size of a cache refers to the amount of data it can store temporarily for quick access by the CPU. Cache sizes can vary significantly depending on the system architecture, typically ranging from a few kilobytes (KB) to several megabytes (MB). Common levels of cache include L1, L2, and L3, with L1 being the smallest and fastest, and L3 being larger but slower. The specific size and configuration can impact overall system performance.
Should I buy a Intel core i5-4670k quad-core desktop processor 3.4 ghz 6 mb cache that is $391 or a Intel core i5-4670k quad-core desktop processor 3.4 ghz 6 mb cache $274
Primary cache memory, often referred to as CPU cache, is typically measured in terms of capacity (e.g., kilobytes or megabytes) and speed (latency). The cache hierarchy includes levels like L1, L2, and L3, with L1 being the fastest and smallest, while L3 is larger but slower. Performance can also be assessed by metrics such as hit rate (the percentage of cache accesses that are successful) and miss rate. These measurements help evaluate the effectiveness of the cache in reducing access times to main memory.
An L2 cache is a small amount of RAM built directly into the processor. This memory is faster than the main system memory. It is used so that the processor doesn't have to fetch data from main memory as often, and thus making many tasks on the computer, such as video games and editing faster. A 6 MB L2 cache is considered good by today's standards.
A megabyte is a unit of information storage equal to 8,388,608 bits. The cache buffer is an area of extremely fast-access memory used by the processor, so the larger the area, the more data could take advantage of this speed. The "difference" between the two is self-evident.
It has 64 KB of L1 cache per core and 4 MB of L2 cache.
The computation performs 8 FLOPS on 2 cache lines, i.e., 8 FLOPS in 200 ns. This corresponds to a computation rate of 40 MFLOPS
