Looking for high speed benchmark test for the Stratix IV FPGA Dev Kit

I see that the Stratix IV GX development kit with EP4SGX230KF40C2N FPGA is compliant to PCI Express 2.0 x8 (eight lane). Given that each PCIe 2.0 lane can transfer 500 MB/s, eight lanes in aggregate should be able to transfer 4 GB/s (yes, Giga Bytes per second). Therefore, I'm assuming that this means that the development board/FPGA can receive data at this rate (4 GB/s).  

 

Questions: 

1. Is the above a correct assumption?  

2. Are there any benchmark studies (white papers, etc.) illustrating actual 

high-speed data transfer rates (please send a link)? 

3. Is there a PCIe "core license" I need to purchase? 

4. Is there a particular Quartus license I need to purchase (and what's the  

cost)?  

 

I need feedback before I make a purchase for my group. 

 

 

Thanks,

The PCI-E resource center on Altera's website:

The achievable bandwidth is highly dependent on your design. This reference design document has some benchmark results with explanations about bandwidth calculations and theoretical limits:

Oh and as far as licensing the cores and software, talk to your local Altera sales rep.

Perfect, just the information I was looking. 

 

Thanks Jake,
