ATI Mobility Radeon 7500

The ATI Mobility Radeon 7500 is a 150 nm mobile graphics processor from AMD, built around the M7 chip and Rage 7 architecture. It holds the 50th percentile position in the database's GPU rankings, placing it exactly at the median of all recorded graphics parts. The data sheet lists no benchmark scores — the benchmark array is empty and the average score is 0 — so its standing rests on its raw specification metrics: a 280.0 MPixel/s pixel rate, a 560.0 MTexel/s texture rate, and a 3.200 GB/s memory bandwidth.

Benchmark Performance

With an empty benchmark array and an average score of 0, the Mobility 7500 offers no direct synthetic or game-derived scores to analyze. The percentile field, however, places the card at 50 — exactly the median of all GPUs in the database. This suggests that, in the absence of measured results, the database estimates the Mobility 7500 as a mid-pack performer rather than a low-end or high-end outlier.

The raw throughput numbers tell a more specific story. The pixel rate of 280.0 MPixel/s and texture rate of 560.0 MTexel/s show a 2:1 ratio between texture and pixel output, which aligns with the hardware configuration of 2 texture mapping units and 1 render output unit. The texture rate being double the pixel rate means that, in shader-light workloads typical of the DirectX 7.0 era, texture fetch throughput is not the bottleneck; the single ROP caps fill-rate-bound scenes.

Memory bandwidth is 3.200 GB/s, delivered over a 64-bit bus with 200 MHz DDR memory running at 400 Mbps effective. That bandwidth is modest by any modern standard, but for a 2001 mobile part it reflects the constraints of the IGP form factor. The 32 MB frame buffer further limits what the card can do at higher resolutions — a point developed later in this analysis.

Because there are no rival scores in the nearestRivals field, percentage deltas cannot be computed. The 50th percentile, however, implies that roughly half of all GPUs in the database are faster and half are slower — a useful positional anchor even without explicit rival comparisons.

Who Should Consider It

The Mobility 7500 is an integrated graphics solution — its slot width is listed as IGP — aimed squarely at portable devices. Display outputs are marked "Portable Device Dependent," confirming that this is a laptop-class part rather than a desktop add-in board. The 32 MB DDR frame buffer and 64-bit bus make it suitable for the games and applications of its 2001 release window, when DirectX 7.0 titles were the norm.

Users who should consider this part are those running legacy software that targets DirectX 7.0 or OpenGL 1.3. The 3.200 GB/s bandwidth and 280.0 MPixel/s pixel rate are sufficient for low-resolution, low-detail rendering of that era's titles, but the 32 MB memory capacity will constrain texture-heavy scenes. Higher resolutions will quickly exhaust the frame buffer, and the single ROP will limit fill-rate-bound effects such as alpha-blended particles or large full-screen passes.

This is not a card for modern workloads. The absence of Vulkan support and the DirectX 7.0 API ceiling mean that any title requiring DirectX 8 or later will not run. For collectors or retro-laptop enthusiasts, however, the Mobility 7500 represents a genuine mid-range mobile GPU of its generation — the 50th percentile ranking reinforces that it was neither a flagship nor an entry-level part, but a mainstream mobile option.

How It Compares

The nearestRivals field in the data is empty, so no direct rival comparisons with percentage deltas are available. The database does, however, record the Mobility 7500's predecessor and successor: the M6 and M9, respectively. The M7 chip at the heart of this card sits between those two generations, indicating a stepwise evolution in AMD's mobile GPU line. Without specification data for the M6 or M9, the exact performance deltas cannot be quantified, but the generational placement implies that the Mobility 7500 improved on the M6's capabilities and was itself superseded by the M9.

The 50th percentile standing offers an indirect comparison point: this part sits at the midpoint of all GPUs in the database. In practical terms, that places it above the low-end mobile parts that would cluster in lower percentiles and below the high-end desktop and workstation cards that occupy the upper ranges. The 150 nm process node and 60 million transistors on a 68 mm² die with a transistor density of 882.4K per mm² reflect the manufacturing technology of the era, which inherently limited the performance envelope compared with later generations.

Power and Cooling

The Mobility 7500 carries a TDP of 27 W. This is a modest figure that reflects both the 150 nm process node and the integrated nature of the part. The slot width is listed as IGP, meaning the GPU is integrated into a chipset or motherboard rather than installed as a discrete expansion card. Consequently, no power connectors are listed — an integrated part draws its power through the system board rather than through auxiliary PCIe or AGP power cables.

The suggested PSU field is empty, which is expected for an IGP mobile part; laptops and portable devices do not use user-replaceable power supplies in the desktop sense. The 150 nm manufacturing process, with 60 million transistors on a 68 mm² die, gives a transistor density of 882.4K per mm². That density figure, while modest by modern standards, was typical for early-2000s mobile silicon and contributes to the 27 W thermal envelope. The data shows a part that was designed to fit within the thermal and power constraints of a portable chassis, not to push desktop-class performance.

Memory Subsystem

The memory subsystem is defined by three key figures: 32 MB of DDR memory, a 64-bit bus width, and 3.200 GB/s of bandwidth. The 64-bit bus is half the width of many desktop parts of the same era, which directly limits the amount of data that can be moved per clock cycle. The 200 MHz memory clock with 400 Mbps effective data rate (DDR doubles the data rate) produces the 3.200 GB/s figure.

For high-resolution rendering, the 32 MB frame buffer is the primary constraint. A 32 MB buffer can hold a modest amount of geometry and texture data before spilling to system memory, and the 64-bit bus compounds this by limiting how quickly data can be replenished. The 3.200 GB/s bandwidth means that texture-heavy scenes at high resolutions will be bandwidth-limited. The pixel rate of 280.0 MPixel/s, driven by the single ROP, further caps the resolution at which the card can maintain interactive frame rates. In practice, this memory subsystem is best suited to the low-resolution, low-detail settings that were common in the DirectX 7.0 era.

Ray Tracing and Feature Set

The Mobility 7500 has no ray tracing cores and no tensor cores — both fields are null in the data. This is unsurprising for a 2001 GPU, but it is worth stating explicitly: this part has no hardware acceleration for ray-traced effects or machine-learning workloads. The feature set is instead anchored in the fixed-function pipeline of the Rage 7 architecture.

The API support is DirectX 7.0 and OpenGL 1.3, with no Vulkan support. DirectX 7.0 was the last version of DirectX to rely primarily on the fixed-function pipeline, with no programmable shaders in the modern sense. OpenGL 1.3 likewise predates the widespread adoption of shader-based rendering. The texture rate of 560.0 MTexel/s and pixel rate of 280.0 MPixel/s are the concrete limits of this fixed-function design: they represent the maximum rate at which textures can be sampled and pixels can be written, respectively. For the games and applications that target DirectX 7.0, these figures are adequate; for anything newer, the API ceiling is the hard stop.
