Processor Cache Size

How much better will it be if I upgrade my processor to have 1gb cache instead of 512?
same specs…
current: processor
AMD Turion(tm) 64 Mobile Technology ML-32
version x86 Family 15 Model 36 Stepping 2
current speed 1790 MHz
cache size 512 KB
Prospective: 394259-001 Part is in stock.
AMD Turion 64 ML-34 processor – 1.80GHz (Lancaster, 1.0MB of internal L2 cache, AMD PowerNow! technology, 35-Watt Thermal Design Power (TDP))
also- I have suggested upgrades by hp using their part number do I have to use the exact same part number if buying from outside sources…? specs seem to be the same…
It really depends on what you’re going to do with it. With some software you will notice an improvement with 1MB, while others you will see no difference.
Take a look here for an example of the impact L2 cache size has:

In the end, it’s really up to you and if you think the slight performance gain you will see is worth the added cost.
