Highlighted values are higher. LUT counts are shown as published; the LUT4 equivalent is an approximation to compare different LUT types, see how FPGA vendors count logic. Add up to two more devices to this comparison.
Key differences
The RT4G150 has about 19% more logic capacity (152K vs 128K LUT4 equivalents).
They use different logic architectures: the RT4G150 is built from LUT4 and the XC6VLX130T from LUT6, so the raw LUT counts (152K vs 80K) are not directly comparable.
For arithmetic, the XC6VLX130T has 480 DSP48E1 slices against 462 18×18 math blocks on the RT4G150.
The XC6VLX130T has more on-chip memory (9.3 Mb vs 5 Mb).
Both have transceivers: 24 at up to 3.125 Gb/s on the RT4G150 and 20 at up to 6.6 Gb/s on the XC6VLX130T.
Configuration memory: non-volatile (flash) on the RT4G150, sram on the XC6VLX130T.
The RT4G150 is designed with Microchip Libero SoC and the XC6VLX130T with AMD ISE Design Suite.
