Re: How Much Speed Loss Due to Wireless Overhead?
said by ZOverLord  :
They may say they use an ARM processor, and you can find out which models run how fast, but they NEVER post the RAW Mhz per second numbers of the processor inside.
I just saw this thread and wanted to add a couple of points.
First Mhz is really a bad indicator. For example AMD Athlon processors outperform the Intel counterparts at the same physical clock speeds. Besides making comparisons acrosss architectures is even more difficult. That is why all those complex benchmarks are developed to have meaningful tests for particular uses.
The CPU speed of the AP may or may not be that relevant at all even for the two AP using the same CPU. It depends on the design. Some AP implement encryption dedicated hardware. You might have a 33Mhz processor but with dedicated hardware doing the encryption/decryption your performance would perhaps equal to 233Mhz processor or maybe even more.
Also there are two types of AP design. One implements most 802.11b MAC functions (including encryption) in the CPU (SoftAP or HostAP) while the other type firmware AP implements most in the wireless module. Obviously, HostAP design is more vulnerable to Host CPU clocking...
There are some newer cards that can do functions partially on the host CPU (most of the MAC) and partially on the wireless module (encryption assist) as a balance of function vs future upgradeability. |
