Hi,

How much cache memory has the PCIe Intel i350?

Thanks.

Hi Erick,

Is your question concerning the on-chip descriptor buffers for the receive and for the transmit? Or are you looking for other information?

Here is a link to the datasheet in case you need it:

Yes, as the Intel Pro PT (PCIe) that has 192 KB Cache and the Intel Pro ET (PCIe) 256 KB Cache.

Thanks.

Hi Erick,

The numbers you gave do not correspond to any cache structures that are familiar to the engineers I asked. So I think that I still don't understand your question. Can you tell me where the 192 KB and 256 KB numbers came from? If we can see where you got those numbers, then I can probably find an answer for the I350.
