NVIDIA Quadro FX 4500 X2

The NVIDIA Quadro FX 4500 X2 is a professional graphics card built on the Curie architecture using the G71 chip, fabricated by TSMC on a 90 nm process. Released on April 23, 2006, it is now end-of-life. The card carries a launch MSRP of 2,799 USD. In the benchmark database, it holds the 50th percentile among all GPUs, yet its average benchmark score is zero, and no individual benchmark results are recorded. This analysis therefore relies entirely on the card’s listed specifications—its memory subsystem, rasterization rates, API support, power requirements, and physical attributes—to characterize its capabilities.

Benchmark Performance

Without any benchmark scores, performance must be inferred from the card’s fixed throughput parameters. The pixel rate is 8.000 GPixel/s, derived from 16 ROPs, and the texture rate is 12.00 GTexel/s, derived from 24 TMUs. These figures define the card’s fill-rate limits for rasterization tasks. The memory bandwidth of 38.72 GB/s, combined with a 256-bit bus and 512 MB of GDDR3 memory, sets the ceiling for data transfer between the GPU and its frame buffer. The absence of benchmark entries in the database means no direct comparisons to other GPUs are possible. The 50th percentile rank is a relative measure—it indicates that the card sits at the median of all GPUs in the database, but without a measured score, this rank carries no performance magnitude. The transistor count of 278 million on a die size of 196 mm² yields a density of 1.4M transistors per mm², reflecting the manufacturing capabilities of the 90 nm process. The base and boost clocks are not listed; only the memory clock of 605 MHz (1210 Mbps effective) is provided. The FP32 and FP16 compute rates are also absent, leaving the raw throughput numbers as the only quantitative performance indicators.

The lack of a shading unit count further complicates compute-oriented assessments. The card’s 24 TMUs and 16 ROPs suggest a design optimized for texture-heavy workloads typical of early 2000s professional applications, but without benchmark data, the practical impact of these counts cannot be validated. The pixel and texture rates are modest by contemporary standards, but they are fixed attributes of this hardware. The 50th percentile ranking implies that, within the database’s historical collection, the card is neither a top performer nor a laggard, but this is a positional statement, not a measured outcome. Users seeking quantitative performance comparisons will find no direct data here; the only concrete numbers are the fill rates, memory bandwidth, and memory capacity.

Memory Subsystem

The memory subsystem consists of 512 MB of GDDR3 memory connected via a 256-bit bus. The memory clock runs at 605 MHz, producing an effective data rate of 1210 Mbps and a peak bandwidth of 38.72 GB/s. This configuration provides a fixed amount of on-board storage for textures, framebuffers, and geometry data. For high-resolution rendering, the 512 MB capacity is a hard limit; larger textures or higher display resolutions will quickly exhaust the available memory. The 256-bit bus width allows a moderate data transfer rate, but the bandwidth is modest by modern standards. The card supports four DVI outputs, which can drive multiple displays simultaneously, but each output’s resolution is constrained by the memory and bandwidth. The memory type GDDR3 is a generation-appropriate technology, and the effective data rate of 1210 Mbps is characteristic of that era. With no shading unit count listed, the compute-to-memory balance cannot be fully assessed, but the TMU and ROP counts (24 and 16) suggest a texture-heavy workload orientation.

The memory bandwidth of 38.72 GB/s is a key bottleneck for high-resolution scenarios. For example, a 1600×1200 framebuffer at 32-bit color requires roughly 7.7 MB per frame; with 512 MB, the card can hold many frames but not large texture sets. The 256-bit bus is a standard width for that period, but the memory clock limits the achievable bandwidth. The card’s memory size and bandwidth are fixed; there is no possibility of expansion. The four DVI outputs are the only display interfaces, and each DVI connection can drive a digital or analog monitor, depending on the adapter. The memory subsystem’s performance is therefore defined by these numbers, and any assessment of high-resolution capability must account for the 512 MB capacity as a strict constraint.

Ray Tracing and Feature Set

The Quadro FX 4500 X2 has no ray tracing cores and no tensor cores, as indicated by the null values for those fields. This means hardware-accelerated ray tracing and AI-based features are not present. The card supports DirectX 9.0c with feature level 9_3, and OpenGL 2.1.2 (full) with partial support for OpenGL 3.x. Vulkan is not supported. These API capabilities limit the card to legacy graphics workloads. The absence of RT and tensor cores aligns with the Curie architecture, which predates those technologies. The card’s feature set is therefore focused on traditional rasterization and fixed-function pipeline operations. The DirectX 9.0c support is the highest DirectX version available; no later DirectX versions are listed. For professional applications that rely on OpenGL 2.1, the card provides full compatibility, while partial OpenGL 3.x support may enable some newer features. No Vulkan support means that modern cross-platform graphics APIs are unavailable.

The lack of dedicated ray tracing hardware is a significant limitation for any workload that requires real-time ray tracing. The absence of tensor cores also precludes any AI-accelerated features such as deep learning super sampling or denoising. The card’s API support is strictly tied to the DirectX 9.0c and OpenGL 2.1 generation, which is a natural fit for CAD, medical imaging, and scientific visualization software of the mid-2000s. The partial OpenGL 3.x support is noteworthy because it indicates some forward compatibility, but it is not full compliance. The card’s feature set is thus defined by what it lacks: no ray tracing, no tensor cores, no Vulkan, and no modern DirectX. These absences are consistent with its release date and architecture, but they mean the card cannot accelerate any of the graphics features that have become standard in later generations.

How It Compares

The database lists no nearest rivals for this card. Consequently, direct numerical comparisons with other GPUs are not possible from the provided data. The card’s position in the product hierarchy is indicated by its predecessor, the Quadro FX Rankine, and its successor, the Quadro FX Tesla. However, no performance deltas or scores are given for these or any other cards. The 50th percentile ranking among all GPUs in the database suggests that the card sits in the middle of the historical performance distribution, but without benchmark scores, this is only a relative indicator. The lack of rival data means that any comparison must be qualitative, based on the card’s own specifications. For instance, the 512 MB memory and 38.72 GB/s bandwidth are the only memory-related figures available. The card’s process node of 90 nm and transistor count of 278 million are fixed attributes. Given the absence of rival metrics, this section cannot provide the typical percentage deltas. The card’s launch MSRP of 2,799 USD places it in a premium segment, but no cost-performance analysis is possible without rival pricing.

The absence of nearest rivals is a notable gap in the database. It means that the Quadro FX 4500 X2 cannot be benchmarked against any specific competing product, such as a comparable ATI FireGL or a consumer GeForce card. The 50th percentile rank, however, gives a coarse indication of its standing relative to the entire database. A percentile of 50 implies that half of all GPUs in the database are slower and half are faster, but this is a global rank, not a head-to-head comparison. The card’s predecessor and successor are named but not scored, so no generational improvement can be quantified. The lack of benchmark data is the primary obstacle to any meaningful comparison. Without scores or rival listings, the only defensible statement is that the card exists in a historical context, positioned between two product lines, and holds a median rank in the database.

Power and Cooling

The card has a thermal design power (TDP) of 145 W. The suggested power supply unit is rated at 300 W. It requires two 6-pin power connectors. The card occupies a dual-slot form factor, with dimensions of 305 mm (12 inches) in length and 111 mm (4.4 inches) in height. The width is not specified. The power connectors and TDP indicate the electrical demands of the card. A 300 W PSU is recommended, which is a modest requirement for a professional card of its era. The dual-slot design suggests a substantial heatsink and fan assembly. The card uses a PCIe 1.0 x16 bus interface, which is the standard for that generation. The display outputs are four DVI ports, which require appropriate adapters for other display types.

The 145 W TDP is a fixed power draw figure; the card will consume up to that amount under load. The 300 W PSU recommendation is the minimum system power supply rating, not the card’s consumption. The two 6-pin connectors are required to supply the card’s power; without them, the card will not function. The dual-slot design means the card occupies two expansion slots in a chassis, which is common for high-end graphics cards of that period. The length of 305 mm is substantial, so case clearance is a consideration. The height of 111 mm is standard for a full-height card. The PCIe 1.0 x16 interface provides the necessary bandwidth for the card’s data transfers. The four DVI outputs are the sole display outputs; no other connectors are listed. The power and cooling requirements are straightforward: a 300 W PSU with two 6-pin connectors, a dual-slot case, and sufficient internal space for a 305 mm long card.

Who Should Consider It

Given the card’s specifications, it is suited for professional workloads that rely on DirectX 9.0c or OpenGL 2.1. The 512 MB memory capacity and 38.72 GB/s bandwidth are sufficient for moderate texture loads, but not for large datasets or high-resolution framebuffers. The 4x DVI outputs enable multi-monitor setups, which is typical for CAD or medical imaging applications. The card’s pixel rate of 8.000 GPixel/s and texture rate of 12.00 GTexel/s provide a baseline for rasterization throughput. However, without benchmark scores, it is not possible to recommend specific resolutions or quality settings. The absence of ray tracing and tensor cores means that workloads requiring those features will not benefit. The card’s end-of-life status suggests that it is no longer produced, but it may still be used in legacy systems. The 145 W TDP and 300 W PSU recommendation make it compatible with a wide range of power supplies, provided they have the required 6-pin connectors.

The card is not appropriate for modern gaming or compute workloads that demand high memory bandwidth, large VRAM, or hardware-accelerated ray tracing. Its DirectX 9.0c support is the highest API version, so any application requiring DirectX 10 or later will not run. The partial OpenGL 3.x support may allow some newer OpenGL features, but full OpenGL 3.x is not guaranteed. The 512 MB memory is a severe limitation for high-resolution textures, and the 38.72 GB/s bandwidth will become a bottleneck for any scene with complex geometry. For users running legacy professional software that is optimized for the Curie architecture, the card can still function. The four DVI outputs are a strong feature for multi-display environments, and the dual-slot cooler is designed to manage the 145 W TDP. The card’s 50th percentile rank suggests it is an average performer in the historical database, but without benchmarks, that rank is only a rough guide.
