Stream Processor: specs and benchmarks

Summary

AMD started Stream Processor sales on 2006. This is a desktop graphics card based on an Ultra-Threaded SE architecture and made with 90 nm manufacturing process. It is primarily aimed at gamer market. 1 GB of GDDR3 memory clocked at 1.3 GHz are supplied, and together with 256 Bit memory interface this creates a bandwidth of 41.47 GB/s.

Compatibility-wise, this is a dual-slot graphics card attached via PCIe 1.0 x16 interface. Its manufacturer default version has a length of 241 mm. 1x 6-pin power connector is required, and power consumption is at 165 Watt.

Form factor & compatibility

This section provides details about the physical dimensions of Stream Processor 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	PCIe 1.0 x16
Length	241 mm
Width	2-slot
Supplementary power connectors	1x 6-pin

VRAM capacity and type

Parameters of memory installed on Stream Processor: 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	GDDR3
Maximum RAM amount	1 GB	of 294912 (Radeon Instinct MI325X)
Memory bus width	256 Bit	of 8192 Bit (Radeon Instinct MI250X)
Memory clock speed	1296 MBps	of 20000 (RTX 5000 Ada Generation Mobile)
Memory bandwidth	41.47 GB/s	of 5,171 GB/s (Radeon Instinct MI300X)

Connectivity and outputs

Types and number of video connectors present on Stream Processor. 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

2x DVI, 1x S-Video

API compatibility

APIs supported by Stream Processor, sometimes including their particular versions.

DirectX	9.0c (9_3)
Shader Model	3.0
OpenGL	2.1 (full) 3.0 (partial)	of 4.6 (GeForce RTX 4090)
OpenCL	N/A
Vulkan	N/A
