The short answer: The more you have up to a reasonable point, the faster the performance.
Cache memory is a special, high-speed memory that is faster than DRAM. It is usually static memory, meaning that rather than being made of cells that contain a capacitor and a transistor, the cells contain 4-6 transistors. That costs a bit more and takes more current than DRAM, but it is fast. Since the cache is all in the CPUs these days, that also helps the speed.
Anyway, since the cache is so fast, the most used data gets held there. So rather than having to fetch it from memory, when the machine might be between clock cycles or the DRAM busy with a refresh cycle, the CPU gets it directly from the cache with less access penalties. So obviously, the more of this special memory is available, up to a certain point, the faster programs can run.
What else can I help you with?
Which factors will least affect the performance of the CPU?
The performance of a CPU is least affected by its age, its size and weight. Performance is instead determined by model, clock speed and size of cache.
Cache memory does not affect the performance of the CPU?
true
Someone told me cache size is more important than gigahertz. What are the cache sizes on these Hp Pavilion desktops with intel Core 2 Quad processors?
They have a four megabyte cache,but neither the cache nor the gigahertz is an adequate description of a CPU's overall performance.
Is level 3 cache faster for the CPU to reach and is larger in size than Level 1 cache?
False
Is cache on a CPU?
CPUs do have a cache (either L1, L2 or L3), but cache is not exclusively on the CPU.
What are the factors affecting CPU performance?
There are many factors. 1. Clock frequency 2. Memory bandwidth 3. L2/L3 cache size 4. Instruction per cycle 5. number of CPU cores.
Where the the L1 cache located?
L3 cache is located on the motherboard or in CPU housing.Hope this help.
Which type of CPU cache has the highest latency?
The Level 3 (L3) cache has the highest latency. The CPU cache is memory that is used to decrease the time that it takes the CPU to access data. Because the data is cached, it can be accessed more quickly. The CPU cache is often found directly on the CPU or built into the CPU. The L3 cache is usually larger than the L1 and L2 cache, but it is searched last. The CPU searches for data in the following order: L1 cache, L2 cache, L3 cache, RAM.
What is the size of the data bus and l1 cache on a core 2 duo CPU?
64 bit data bus and two L1 (64KB) caches; one L1 cache for each core (cpu)
What is the size of the data bus and the L1 cache on a Core 2 Duo CPU?
64 bit data bus and two L1 (64KB) caches; one L1 cache for each core (cpu)
What is the significance of a cache miss in computer systems and how does it impact overall performance?
A cache miss occurs when the CPU cannot find the needed data in the cache memory and has to retrieve it from the slower main memory. This impacts performance by causing a delay in processing instructions, as accessing main memory is slower than accessing the cache. This can lead to decreased overall system performance and efficiency.
What are Limitations of cache?
size. cache memory is situated on the CPU, and stores recently used data, in case the CPU needs again soon. cache memory is many, many times faster than RAM, just RAM is much faster than the HD.
