NVIDIA Quadro4 750 XGL

The NVIDIA Quadro4 750 XGL is a professional workstation graphics card built on the Kelvin architecture with the NV25 chip. Released on February 18, 2002, it is now end-of-life. The card uses a 150 nm process from TSMC, integrating 63 million transistors on a 142 mm² die. It carries 128 MB of DDR memory on a 128-bit bus, delivering 7.200 GB/s of bandwidth, and it occupies a single slot with no auxiliary power connectors. In the benchmark database, the card holds a 50th percentile standing among all GPUs, though its average benchmark score is zero due to the absence of scored entries.

Benchmark Performance

The benchmark database lists no scored entries for the Quadro4 750 XGL; the average benchmark score is zero. This absence of data means that the card's performance cannot be quantified through direct benchmark scores. However, the percentile rank of 50 provides a global reference: it places the card exactly at the median of all GPUs in the database. Half of all GPUs score higher, and half score lower. The raw throughput specifications offer the only quantitative performance indicators. The card achieves a pixel rate of 2.200 GPixel/s and a texture rate of 2.200 GTexel/s, both driven by 8 texture mapping units and 8 render output units. The identical pixel and texture rates indicate a balanced fixed-function pipeline, where each ROP and TMU operates at the same effective rate. Memory bandwidth is 7.200 GB/s, derived from a 128-bit DDR bus operating at an effective 450 Mbps (225 MHz base). This bandwidth is sufficient to feed the fill rates without creating a bottleneck, as the ratio of bandwidth to pixel rate is adequate for the era's typical texture-heavy workloads. The 50th percentile standing suggests that the card was positioned in the middle of the performance spectrum during its lifetime, not as a flagship nor as a low-end part. Because the nearestRivals field is empty, no direct percentage deltas can be cited against specific competitors. The analysis must rely on the absolute rates and the percentile rank alone. The lack of FP32 or FP16 data confirms that the card does not use a unified shader architecture; its performance is defined purely by fixed-function rasterization and texturing, which is typical for a 2002 release. The 8 TMUs and 8 ROPs operate in lockstep to produce the 2.200 GTexel/s and 2.200 GPixel/s figures, meaning that texture fetches and pixel writes are perfectly balanced. This symmetry is a hallmark of the Kelvin architecture, which prioritized consistent viewport rendering for CAD and DCC applications over the more flexible shader pipelines that would follow.

Power and Cooling

The Quadro4 750 XGL is a single-slot card with a suggested power supply rating of 200 W. It requires no auxiliary power connectors, meaning all power is drawn through the AGP 4x slot interface. The TDP is not specified in the data pack, so no wattage figure can be cited; however, the absence of external power connectors and the low 200 W PSU recommendation imply a modest power envelope. The card's 150 nm process node, manufactured by TSMC, houses 63 million transistors on a 142 mm² die, giving a transistor density of 443.7K per mm². This relatively low density for a 150 nm part contributes to the card's thermal characteristics, though no thermal data is provided. The single-slot design and lack of power connectors suggest that cooling is handled by a passive or low-profile active solution, but the exact cooler type is not listed. The 200 W suggested PSU is a system-level recommendation, not the card's own draw, so users should ensure their overall system power stays within that guidance. The bus interface is AGP 4x, which provides both the electrical connection and power delivery. Since the card has no power connectors, the AGP slot must supply all required power, which is typical for cards of this era with a modest transistor count. The 63 million transistors at 150 nm would have drawn a relatively small current, consistent with the lack of auxiliary power. The single-slot form factor further constrains the cooling solution, as the card must fit within a standard slot height without protruding beyond it.

Ray Tracing and Feature Set

The Quadro4 750 XGL does not include dedicated ray tracing cores or tensor cores; both fields are null in the data. This is consistent with its 2002 release, predating the advent of hardware ray tracing and AI acceleration. The card's API support is limited to DirectX 8.1 and OpenGL 1.5, with no Vulkan support. These APIs reflect the fixed-function pipeline era, where shading was handled through vertex and pixel shader models up to version 1.1 in DirectX 8.1. The display outputs comprise 2x DVI and 1x S-Video, enabling dual-monitor professional setups. Memory is 128 MB of DDR on a 128-bit bus, which is adequate for the CAD and DCC workloads of the time but modest by modern standards. The card's texture rate of 2.200 GTexel/s and pixel rate of 2.200 GPixel/s are the primary feature-set indicators, as there are no compute or tensor capabilities to analyze. The absence of Vulkan support means the card cannot run modern Vulkan-based applications, and its OpenGL 1.5 support is similarly dated. For professional users of the era, the feature set was geared toward hardware-accelerated OpenGL viewport rendering, which the 2.200 GTexel/s fill rate would have handled for typical scene complexities. The card's architecture, Kelvin, is a fixed-function design, so it lacks the programmable shader flexibility of later unified architectures. The memory clock of 225 MHz (450 Mbps effective) is a fixed specification, and the 128-bit bus width limits memory bandwidth to 7.200 GB/s, which is a constraint for large textures. The lack of RT and tensor cores means the card is entirely reliant on its fixed-function units for all rendering tasks.

How It Compares

The nearestRivals field in the data pack is empty, so no direct score deltas or rival names can be cited. The card's percentile of 50 places it at the median of all GPUs in the database, which is a meaningful reference point. In the absence of rival data, the comparison must rely on the card's position within its own product lineage. The Quadro4 750 XGL belongs to the Quadro4 Celcius (x50) generation, succeeding the Quadro2 Celcius and preceding the Quadro FX Rankine. The predecessor, Quadro2 Celcius, would have been built on an older architecture, while the successor, Quadro FX Rankine, introduced a new architecture with likely higher fill rates. However, no specific numbers are available for these parts in the pack. The 50th percentile standing indicates that the card is neither a performance outlier nor a low-end part; it sits squarely in the middle of the historical GPU performance distribution. Given the empty rival list, the only quantitative comparison is the percentile itself, which serves as a global benchmark across all GPUs. The card's 2.200 GPixel/s pixel rate and 7.200 GB/s bandwidth are the figures that would have positioned it against contemporaries, but without rival entries, these remain standalone specifications. The lack of benchmark scores further limits comparison; the average benchmark score of zero means no performance deltas can be computed. Thus, the Quadro4 750 XGL's competitive standing is best understood through its median percentile and its place between two known generations in the Quadro family. The successor, Quadro FX Rankine, is a later generation, so it likely benefits from architectural improvements, while the predecessor, Quadro2 Celcius, is older and likely slower, but again, no numeric deltas are available. The card's own specifications—8 TMUs, 8 ROPs, and a 128-bit memory bus—define its ceiling, and the 50th percentile confirms that this ceiling was unremarkable yet competent within the broader GPU landscape.
