ATI Fire GL4

The ATI Fire GL4 is an end-of-life professional workstation graphics card from AMD’s Fire GL generation, built on IBM’s 180 nm process with a 100 mm² die. Released in March 2001, it occupies a specific niche in the benchmark database, holding a 50th percentile ranking among all GPUs tracked, though it carries no recorded average benchmark score. This analysis draws solely on the provided specification data and the card’s position within its generation.

Benchmark Performance

The Fire GL4 has no recorded benchmark scores in the database, meaning its performance cannot be quantified through direct synthetic or application-based testing data. The absence of scores, combined with a 50th percentile ranking, indicates that the card sits at the median of all GPUs in the database, a position that suggests mid-pack capability among the diverse range of hardware tracked, but without concrete deltas to compare against specific rivals.

The card’s raw throughput figures provide a baseline for interpreting its expected performance. The pixel rate is 150.0 MPixel/s, and the texture rate is 600.0 MTexel/s. These numbers, while not benchmark scores, establish the card’s fundamental processing limits. The texture rate is four times the pixel rate, which aligns with the hardware configuration of 4 texture mapping units (TMUs) and 1 render output unit (ROP). This ratio means the Fire GL4 can theoretically apply textures to geometry at a rate four times faster than it can write final pixels to the framebuffer, a characteristic that often benefits texture-heavy workloads but can bottleneck pixel-heavy scenes.

Because the nearestRivals array is empty, there are no percentage deltas to report against competing products. The data shows that the Fire GL4’s performance class must be inferred from its internal specifications rather than direct comparisons. The 50th percentile placement does, however, position it exactly in the middle of all GPUs in the database, suggesting that half of the tracked hardware is faster and half is slower. This median standing is consistent with a professional card from 2001 that was not designed for maximum consumer gaming performance but rather for specialized workstation tasks.

Ray Tracing and Feature Set

The Fire GL4 predates dedicated ray tracing and tensor core hardware; the specification pack lists no RT cores and no tensor cores. Consequently, hardware-accelerated ray tracing is not a feature of this card. Any ray tracing workloads would have to be handled through software or older rasterization-based methods, which were the norm for the era. The absence of these cores means the card’s feature set is firmly rooted in the DirectX 6.0 and OpenGL 1.2 API levels.

The API support is limited to DirectX 6.0 and OpenGL 1.2, with no Vulkan support listed. DirectX 6.0 dates to the late 1990s, and OpenGL 1.2 was current around the same period. This restricts the Fire GL4 to applications and games that use these older API versions. For professional use, OpenGL 1.2 support would have been relevant for CAD and 3D modeling software of that time, but modern applications requiring newer API features will not run on this hardware. The card’s display outputs are 2x DVI and 1x S-Video, which reflects the connectivity standards of its release period, offering dual digital outputs for workstation monitors.

How It Compares

The nearestRivals data is empty, so no direct comparisons can be made against specific competing products. The card’s predecessor is the Rage GL, and its successor is the FireGL, but the database does not provide benchmark scores or performance deltas for either. The Fire GL4 sits between these two generations with no quantitative data to establish how much faster or slower it is than either.

Without rival scores, the comparison must rely on the internal architecture. The Fire GL4 uses the GT1000 chip from IBM, built on a 180 nm process. The Rage GL, as a predecessor, would logically use an older process and likely fewer features, but no specs are provided to confirm this. The successor FireGL would presumably improve upon the Fire GL4, but again, no numbers are available. The 50th percentile ranking provides the only positional context, placing the Fire GL4 exactly at the median of all GPUs in the database, which implies it is neither a top-tier performer nor a bottom-tier one within the historical hardware tracked.

Who Should Consider It

Given the lack of benchmark scores, recommendations must be grounded in the card’s raw specifications and the API support. The Fire GL4 is suited for legacy professional applications that rely on OpenGL 1.2 and DirectX 6.0. For resolution and settings, the card’s pixel rate of 150.0 MPixel/s and texture rate of 600.0 MTexel/s suggest it can handle lower resolutions with moderate settings. At higher resolutions, the pixel rate becomes the limiting factor, as the single ROP will struggle to fill a large framebuffer quickly.

The 128 MB memory size and 9.600 GB/s bandwidth further constrain high-resolution performance. For a card of this era, 128 MB was a reasonable amount, but it is insufficient for modern high-resolution textures. Users running legacy software at 1024x768 or lower resolutions with reduced texture quality would find the Fire GL4 adequate. The data does not support recommendations for 1080p or beyond, as the pixel rate and bandwidth would likely cause significant performance drops. The card also lacks any modern features like hardware ray tracing, so it is not suitable for any workload requiring those capabilities.

Memory Subsystem

The Fire GL4 is equipped with 128 MB of DDR memory on a 256-bit bus. The memory clock is 150 MHz, with an effective data rate of 300 Mbps. This configuration yields a bandwidth of 9.600 GB/s. The 256-bit bus width is a notable feature, as it allows the memory controller to transfer data across a wide path, partially compensating for the relatively low clock speed.

At high resolutions, the memory bandwidth becomes a critical factor. 9.600 GB/s is modest by modern standards, but for the card’s intended era and workload, it provides a baseline for texture streaming and framebuffer operations. The 128 MB capacity limits the texture detail and scene complexity that can be loaded into VRAM. For professional 3D modeling with large textures, this would be a bottleneck. The wide bus width helps maintain throughput efficiency, but the effective data rate of 300 Mbps is low, meaning the card will struggle with data-intensive tasks such as large, high-resolution textures or complex geometry buffers. The memory subsystem is adequate for basic 2D and early 3D workloads but is not designed for high-fidelity, high-resolution rendering.

Power and Cooling

The Fire GL4 has no listed TDP, but the suggested PSU is 200 W. This low power supply recommendation indicates that the card is not power-hungry, consistent with its 180 nm process node and modest specifications. The card is single-slot and requires no power connectors, drawing all its power from the AGP Pro 8x bus interface. This makes installation straightforward, as no additional power cables are needed.

The absence of a TDP figure means the exact power draw is not quantified, but the 200 W PSU suggestion provides an upper bound for system requirements. A 200 W power supply is sufficient for the card and a basic system of that era. The single-slot design and lack of power connectors also imply that cooling is passive or requires only minimal airflow. The card’s low power characteristics are consistent with its performance class, as a card with a 150.0 MPixel/s pixel rate and 600.0 MTexel/s texture rate does not generate excessive heat. The 180 nm process, while large by modern standards, was typical for the time and did not require elaborate cooling solutions. Overall, the power and cooling requirements are minimal, making the Fire GL4 easy to integrate into a workstation of its period.
