Mach 64 GX: specs and benchmarks
Summary
ATI started Mach 64 GX sales 1 January 1995. This is a desktop card based on 600 nm manufacturing process and primarily aimed at gamers. 2 MB of VRAM memory clocked at 0.01 GHz are supplied, and together with 64 Bit memory interface this creates a bandwidth of 80.0 MB/s.
Compatibility-wise, this is a single-slot graphics card attached via PCI interface.

Form factor & compatibility
This section provides details about the physical dimensions of Mach 64 GX and its compatibility with other computer components. This information is useful when selecting a computer configuration or upgrading an existing one. For desktop graphics cards, it includes details about the interface and bus (for motherboard compatibility) and additional power connectors (for power supply compatibility).
| Interface | PCI | |
| Width | 1-slot |
VRAM capacity and type
Parameters of memory installed on Mach 64 GX: its type, size, bus, clock and resulting bandwidth. Note that GPUs integrated into processors have no dedicated memory and use a shared part of system RAM instead.
| Memory type | VRAM | |
| Maximum RAM amount | 2 MB | of 294912 (Radeon Instinct MI325X) |
| Memory bus width | 64 Bit | of 8192 Bit (Radeon Instinct MI250X) |
| Memory clock speed | 10 MHz | of 20000 (RTX 5000 Ada Generation Mobile) |
| Memory bandwidth | 80.0 MB/s | of 5,171 GB/s (Radeon Instinct MI300X) |
Connectivity and outputs
Types and number of video connectors present on Mach 64 GX. As a rule, this section is relevant only for desktop reference graphics cards, since for notebook ones the availability of certain video outputs depends on the laptop model, while non-reference desktop models can (though not necessarily will) bear a different set of video ports.
| Display Connectors | 1x DB13W3 |
API compatibility
APIs supported by Mach 64 GX, sometimes including their particular versions.
| DirectX | None | |
| OpenGL | None | of 4.6 (GeForce RTX 4090) |
| OpenCL | None |
