Families
Virtex-E
The Virtex-E family was introduced in September 1999 on a 180 nm process technology. Virtex-E includes a two million system gate device and supports twice the system-gate density and has a 50 percent higher I/O performance than the original Virtex FPGAs.
Virtex-II
Xilinx introduced Virtex-II family in January 2001 on 150 nm process technology, and Virtex-II Pro family in March 2002 on 90 nm process technology. The Virtex-II and Virtex-II Pro families are considered legacy devices, and are not recommended for use in new designs, although they are still produced by Xilinx for existing designs.
Virtex-4
The Virtex-4 family are considered legacy devices, and are not recommended for use in new designs, although they are still produced by Xilinx for existing designs.

Virtex-5
The Virtex-5 family was introduced in May 2006 on 65 nm process technology. The Virtex-5 LX and the LXT are intended for logic-intensive applications, and the Virtex-5 SXT is for DSP applications. With the Virtex-5, Xilinx changed the logic fabric from four-input LUTs to six-input LUTs. With the increasing complexity of combinational logic functions required by SoC designs, the percentage of combinational paths requiring multiple four-input LUTs had become a performance and routing bottleneck. The new six-input LUT represented a tradeoff between better handling of increasingly complex combinational functions, at the expense of a reduction in the absolute number of LUTs per device. The Virtex-5 series is a 65 nm design fabricated in 1.0 V, triple-oxide process technology.National Instruments. Advantages of the Xilinx Virtex-5 FPGA " June 17, 2009. Retrieved June 29, 2010.
Virtex-6
The Virtex-6 family was introduced in February 2009 on a 40 nm process technology for compute-intensive electronic systems, and the company claims it consumes 15 percent less power and has 15 percent improved performance over competing 40 nm FPGAs.
Virtex-7
The Virtex-7 family was introduced in June 2010 on a 28 nm process technology, and is reported to deliver a two-fold system performance improvement at 50 percent lower power compared to previous generation Virtex-6 devices. In addition, Virtex-7 doubles the memory bandwidth compared to previous generation Virtex FPGAs with 1866 Mbit/s memory interfacing performance and over two million logic cells.EE Times.

Virtex-7 (3D)
In 2011, Xilinx began shipping sample quantities of the Virtex-7 2000T FPGA, which combines four smaller FPGAs into a single package by placing them on a special silicon interconnection pad (called an interposer) to deliver 6.8 billion transistors in a single large chip. The interposer provides 10,000 data pathways between the individual FPGAs – roughly 10 to 100 times more than would usually be available on a board – to create a single FPGA.Don Clark, The Wall Street Journal.

Retrieved November 18, 2011.David Manners, Electronics Weekly. " October 25, 2011. Retrieved November 18, 2011. In 2012, using the same 3D technology, Xilinx introduced initial shipments of their Virtex-7 H580T FPGA, a heterogeneous device, so called because it comprises two FPGA dies and one 8-channel 28Gbit/s transceiver die in the same package.Electronic Product News. " May 15, 2012. Retrieved June 12, 2012.
As Xilinx introduced new high capacity 3D FPGAs, including Virtex-7 2000T and Virtex-7 H580T products, these devices began to outpace the capacity of Xilinx’s design software, which led the company to completely redesign its tool set. The result was the introduction of the Vivado Design Suite, which reduces the time needed for programmable logic and I/O design, and speeds systems integration and implementation compared to the previous software.EDN.
