3.7.5. 10GbE Design Performance and Resource Utilization
Table 3–7 provides the estimated performance and resource utilization of the 10GbE
design example obtained by compiling the design with the Quartus II software
targeting the Stratix IV GX (EP4SGX230KF40C2ES) device with speed grade –2.
Table 3–8 provides the estimated performance and resource utilization of the 10GbE
design example obtained by compiling the design with the Quartus II software
targeting the Cyclone V GX (5CGXFC7D6F31C6) device with speed grade –6.
