The CL-GD5434 was part of the "Alpine" family of chips, now with a 64-bit internal memory interface. Only supports 64-bit mode if equipped with 2 MB memory. Commonly equipped with 1 MB. 32bpp True Color support, it also had a 64-bit BitBLT engine. Only the CL-GD5434 was also available on the ISA bus. Its core clock ran at 135 MHz with memory speed either 60 MHz (5434) or 80 MHz (5436).
The CL-GD5436 was simply an optimized version of the 5434, adding support for EDO DRAMs thus supporting a faster memory clock. Packed-24 acceleration.

Competition
1994 was a competitive year in the graphics card market. Tseng Labs had their ET4000/W32P, ATI introduced Mach64, S3 had Vision864 and Vision964, and Number Nine introduced Imagine 128, the world's first 128-bit graphics processor. All were moving to the PCI architecture on brand new Pentium motherboards. Tseng Labs' ET4000/W32P was considered the fastest for DOS performance, with S3's Vision964 and ATI's Mach64 running a close 2nd. There was still a good market for VESA Local Bus cards in 1994, as nearly everyone still had a 486. As such, it was common for graphics card manufacturers to release cards in both VLB and PCI variants (including those based on the CL-GD543x series).
