For AMD processors, yes. 1 mb of L2 cache (per core) is the most they sell atm.

Yes it does make a diff, basicly it allows for more data to be store and makes for less trips back the the RAM for information. The memory used for cache is very fast so it speeds things up.

Ya. The 170 is the most cache you can get from AMD. Great friggin chip.

The 165 has the same cache, and is cheaper too....but only a 9x multi

The difference between 1MB Level II Cache and 512 in AMD processors is not as markedly different as the Intel level II Cache increases.

You will not find large differences with AMD since the memory controller and very large Level I caches are on chip. One must take into account the delay (latency) that larger caches can bring when valuable time is spend accessing the cache when the data is not there. The time read delay creates a stall which necessitates a queue request for data retrieval from the hard drive.

Since the Intel's memory controller is off-chip these latencies are inherent in their design so the larger caches are of more benefit.

So yes, it does make a difference. Not a large one but a difference nevertheless. You will find the difference in large database work, graphical rendering whilst processing graphics and large bank data distribution. Otherwise the difference will be minimal.

Of course any benchmarks that rely on cache will also show greater benefit than reality.

I think the 165 and the 170 are best value for money. The 175 costs quite a bit more than the 170.

Im planning on getting a 165 or 170 when i get money to upgrade.
