Xilinx FPGA Series

Jump to solution

I am introducing myself to the development with Xilinx FPGAs whith the Artix 7 series. Can someone guide me about what are the differences and advantages offerted by the Kintex 7 Series compared to the Artix 7 series?

Welcome to the Forum and to FPGAs!

The 7-Series are great FPGAs to start with!  There are lots of inexpensive boards with 7-Series FPGAs that you can buy.  Also, you'll be using the latest Xilinx toolset called Vivado to work with these FPGAs/boards.  Lots of people on this Forum are familiar with 7-Series FPGA and Vivado.  So, you can count on getting some help.

You will find a nice summary of the 7-Series FPGAs in Xilinx document, DS180.  There you will see that the 7-Series FPGAs include:

  • Spartan®-7 Family: Optimized for low cost, lowest power, and high
    I/O performance. Available in low-cost, very small form-factor
    packaging for smallest PCB footprint.

  • Artix®-7 Family: Optimized for low power applications requiring serial
    transceivers and high DSP and logic throughput. Provides the lowest
    total bill of materials cost for high-throughput, cost-sensitive
    applications.

  • Kintex®-7 Family: Optimized for best price-performance with a 2X
    improvement compared to previous generation, enabling a new class
    of FPGAs.

  • Virtex®-7 Family: Optimized for highest system performance and
    capacity with a 2X improvement in system performance. Highest
    capability devices enabled by stacked silicon interconnect (SSI)
    technology.

Cheers,
Mark

Conceptually they are very similar, siblings in the same family - Arix-7 is the low-end (with transceivers - Spartan-7 is the low-end without transceivers), Kintex-7 is mid-range (in size, not necessarily speed), and Virtex-7 is the high-end (device size & I/O)

same architecture: same fabric slice/CLB, same clocking structures, same BlockRAM, same DSP

Artix has the GTP transceiver while Kintex has the faster GTX

Artix is all HR I/O while Kintex is either going to be a mix of HR & HP (like the 7K325T) or all HR (like the 7K355T)... The HP (high perfomance I/O is limited to 1.8V and really optimized for DDR3 and LVDS).

the fabric is optimized for different power/performance curves - in general, if Artix was a 1, I'd expect Kintex (and Virtex-7) to be ~1.6 in speed (e.g. 60% faster, like Virtex-7)

Different packages too. And device densities.

The intended applications are obviously a bit different - mostly because of I/O interfacing and processing capability.
