ATI FireGL 9500 Z1-128

The ATI FireGL 9500 Z1-128 is a workstation-oriented graphics card built on AMD’s R300 architecture, fabricated by TSMC on a 150 nm process. It packs 110 million transistors on a 215 mm² die, with a transistor density of 511.6K per mm². The card features 4 texture mapping units and 4 render output units, delivering a pixel rate of 1.300 GPixel/s and a texture rate of 1.300 GTexel/s. It supports DirectX 9.0 (feature level 9_0) and OpenGL 2.0, and its production status is end-of-life, with a release date of September 30, 2002. The card sits at the 50th percentile among all GPUs in the database, though its average benchmark score is zero, and it has no nearest rivals listed.

How It Compares

The data for the ATI FireGL 9500 Z1-128 shows no nearest rivals in the fact pack. This means there are no direct comparison points from the benchmark database to position this card against competing models. Without rival scores or delta percentages, the analysis must focus on the card’s absolute specifications and its percentile placement. The 50th percentile indicates that, in the historical distribution of all GPUs tracked by the database, this card lands exactly in the middle — neither a standout performer nor a laggard. However, since the average benchmark score is zero, this percentile is likely derived from the card’s feature set and rasterization rates rather than actual measured workloads. In practical terms, the absence of rivals means the FireGL 9500 Z1-128 occupies a unique niche in the database, likely representing a specialized workstation product that was not widely benchmarked alongside consumer or other professional cards.

The card’s predecessor is the Fire GL, and its successor is the FirePro Terascale, placing it in a generational transition within AMD’s professional lineup. The generation field lists it under FireGL (9000), which suggests it belongs to the early 9000-series of FireGL products. With a single-slot design and no power connectors, it was clearly aimed at systems with modest power delivery, as indicated by the suggested power supply of 200 W. The AGP 8x bus interface further situates this card in the early 2000s platform era, before PCIe became standard. Because no rival data is provided, the comparison section must rely on the card’s internal specifications and its historical context rather than head-to-head benchmark deltas.

Ray Tracing and Feature Set

The ATI FireGL 9500 Z1-128 does not list any ray tracing cores or tensor cores in its specification. This is consistent with its DirectX 9.0 support, as ray tracing hardware did not appear in GPUs until much later generations. The card’s API support is limited to DirectX 9.0 (feature level 9_0) and OpenGL 2.0; there is no Vulkan support listed. For its era, DirectX 9.0 enabled programmable shaders through pixel and vertex shader models 2.0, which was a significant step forward from fixed-function pipelines. OpenGL 2.0 similarly brought shader-based rendering to professional applications, making this card suitable for early CAD and 3D modeling workloads that relied on OpenGL for viewport acceleration. The absence of tensor cores means no dedicated AI or machine learning acceleration, and the lack of RT cores means hardware-accelerated ray tracing is not available. Instead, the card’s feature set is built around traditional rasterization, with its 4 TMUs and 4 ROPs handling texture mapping and pixel output. The pixel rate of 1.300 GPixel/s and texture rate of 1.300 GTexel/s indicate balanced throughput for a card of this vintage, though those figures are modest by modern standards. The display outputs are limited to 2x DVI, which was typical for professional cards targeting dual-monitor setups in workstations. Overall, the feature set is firmly rooted in the early 2000s, with no modern acceleration features beyond the basic shader model support.

Memory Subsystem

The ATI FireGL 9500 Z1-128 comes equipped with 128 MB of DDR memory, operating at a memory clock of 310 MHz with an effective data rate of 620 Mbps. The memory bus width is 256 bit, which yields a total bandwidth of 19.84 GB/s. This configuration was competitive for professional cards at the time of its release, as 128 MB was sufficient for typical CAD textures and moderate-resolution framebuffers. The 256-bit bus width is a notable asset, as it allows the memory controller to move data more efficiently than narrower buses, even at a relatively low clock speed. For high-resolution workloads, the 19.84 GB/s bandwidth imposes a hard limit; at resolutions beyond 1600x1200, texture-heavy scenes could exceed the available memory bandwidth, leading to frame drops or reduced texture detail. The DDR memory type, as opposed to DDR2 or GDDR3, reflects the 2002 release period, and the effective 620 Mbps rate is modest. In professional applications, the memory subsystem matters less for raw gaming frame rates and more for maintaining consistent viewport performance when rotating or zooming complex models. The 128 MB capacity also means that large datasets, such as high-polygon models or high-resolution textures, could overflow into system memory over the AGP 8x bus, which would incur significant performance penalties. The 256-bit bus partially mitigates this by providing a wide path for data transfers, but the overall bandwidth figure remains the limiting factor for any resolution above standard-definition workstation displays. The card’s 4 ROPs further constrain fill-rate performance, as they must write pixels to the framebuffer at the 1.300 GPixel/s rate, which aligns with the memory bandwidth — a balanced but not overprovisioned design.

Benchmark Performance

The benchmark data for the ATI FireGL 9500 Z1-128 shows an average benchmark score of zero, and the nearest rivals list is empty. As a result, there are no percentage deltas to report against competing cards. The percentile rank of 50 places it at the median of all GPUs in the database, but this rank must be interpreted cautiously given the zero score. In the absence of measured performance data, the rasterization rates provide the only quantitative basis for analysis. The pixel rate of 1.300 GPixel/s and texture rate of 1.300 GTexel/s indicate that the card can process 1.3 billion pixels and 1.3 billion texels per second, respectively. These figures are identical, suggesting a design where every pixel operation is paired with a texture fetch, which is typical for early DirectX 9 hardware. For comparison, a card with higher ROPs or TMUs would show a higher rate in one dimension, but this card’s balanced 4-to-4 configuration means neither fill rate nor texture rate is a bottleneck over the other. The memory bandwidth of 19.84 GB/s, when divided by the pixel rate, yields approximately 15.26 bytes per pixel, which is ample for 32-bit color at moderate resolutions but becomes tighter for multi-textured scenes. Since no rival scores exist, the performance analysis must rely on these derived ratios. The zero benchmark score likely indicates that the database has no recorded runs for this specific card, possibly due to its professional focus or limited availability. In practice, the card’s performance would be constrained by its 128 MB memory capacity and 4 ROPs, making it suitable for entry-level workstation tasks but not for high-end 3D rendering. The 50th percentile, if interpreted as a relative ranking, suggests that half of all GPUs in the database outperform it and half underperform it, but without a score, this is a nominal placement rather than a measured result.

Who Should Consider It

The ATI FireGL 9500 Z1-128 is best suited for users working with legacy professional applications that rely on OpenGL 2.0 or DirectX 9.0. Given its 128 MB memory and 19.84 GB/s bandwidth, it is appropriate for 2D CAD drafting, basic 3D modeling, and viewport manipulation of low-to-moderate polygon counts. At standard resolutions, such as 1024x768 or 1280x1024, the pixel rate of 1.300 GPixel/s can maintain smooth interaction for simple scenes, and the 256-bit bus provides sufficient bandwidth for single-textured surfaces. However, users considering this card for high-resolution work — defined here as anything above 1600x1200 — would quickly encounter the memory bandwidth ceiling, leading to stalls when textures exceed the 128 MB framebuffer. The lack of tensor cores and RT cores means it cannot handle modern AI-accelerated or ray-traced workloads, so it is not suitable for contemporary content creation. The single-slot design and absence of power connectors make it easy to install in older AGP 8x motherboards with a 200 W power supply. For retro computing enthusiasts or those maintaining legacy workstations, the card’s dual DVI outputs support dual-monitor setups, which is a practical feature for spreadsheet or code-driven tasks. The 50th percentile ranking suggests it is neither a high-performance outlier nor a weakling in the broader GPU landscape, but the zero benchmark score indicates that it was not a popular choice for testing. In summary, this card is for users who need a period-correct professional GPU for compatibility with early 2000s software, not for those seeking modern performance or advanced features. Its 4 TMUs and 4 ROPs deliver balanced but modest throughput, and its 19.84 GB/s bandwidth defines its ceiling for anything beyond basic workstation usage.
