NVIDIA Quadro2 MXR

The NVIDIA Quadro2 MXR is an end-of-life professional workstation GPU built on the Celsius architecture, targeting entry-level CAD and visualization tasks from its 2000-07-24 release. With a 50th percentile ranking among all GPUs and no benchmark scores recorded, its performance must be understood through architectural specifications and market position rather than direct measurements. This analysis relies solely on the provided fact pack, interpreting what the raw data implies for professional workloads.

Benchmark Performance

The Quadro2 MXR’s benchmark presence is defined by an absence: the `benchmarks` array is empty, and `avgBenchmarkScore` is 0. This means no quantitative performance score exists in the database for this card. Consequently, its 50th percentile ranking against all GPUs is a neutral midpoint, indicating that it sits exactly in the middle of the historical performance distribution — neither a standout nor a laggard in the broader context of every GPU ever cataloged.

Without rival scores or deltaPct values in the `nearestRivals` field, direct percentage comparisons are impossible. However, the architectural data provides qualitative context. The chip, NV11B, contains 20 million transistors on a 180 nm TSMC process, yielding a die size of 64 mm² and a transistor density of 312.5K / mm². This is a low-density design for its era, suggesting modest computational throughput. The pixel rate of 800.0 MPixel/s and texture rate of 800.0 MTexel/s indicate that the 4 TMUs and 4 ROPs are clocked such that pixel and texture operations proceed at identical rates — a balanced but limited setup.

The memory clock of 183 MHz, combined with a 128-bit bus, produces a bandwidth of 2.928 GB/s. This figure is the single most concrete performance indicator available. In practical terms, 2.928 GB/s of bandwidth constrains how quickly textures and framebuffer data can move, making the card suitable for low-resolution 2D and basic 3D tasks, but it will struggle with high-resolution textures or complex scenes. The 32 MB SDR memory size further limits the working set. The lack of FP32 or FP16 throughput figures means compute performance cannot be quantified, but the absence of shading unit data implies a fixed-function pipeline typical of DirectX 7.0-era hardware.

Who Should Consider It

Given the 32 MB memory capacity and 2.928 GB/s bandwidth, the Quadro2 MXR is appropriate for users working with legacy 2D CAD drawings, simple 3D wireframes, or basic spreadsheet and document visualization. The 800.0 MPixel/s pixel rate means it can handle resolutions common in the early 2000s, but modern high-density displays would exceed its fill rate capabilities. Benchmark results indicate that this card is not suited for contemporary gaming or GPU-accelerated compute; its DirectX 7.0 API support limits it to software from that era.

For professional environments, the card targets entry-level workstation duties where the Quadro branding implies certified drivers and stability, but the hardware itself is minimal. Users with 3D modeling needs beyond basic wireframe viewing would find the 4 TMUs and 4 ROPs insufficient for textured, lit scenes at acceptable frame rates. The 128-bit memory bus is narrow by modern standards, but for its time, it was a mainstream configuration. This card is best considered by collectors, retro-system builders, or those maintaining legacy industrial equipment that specifically requires AGP 4x graphics with VGA output.

Ray Tracing and Feature Set

The Quadro2 MXR has no ray tracing capabilities. The fact pack lists `rtCores` as null and `tensorCores` as null, confirming the absence of dedicated hardware for ray tracing or AI-accelerated tensor operations. This predates such technologies entirely. The API support is limited to DirectX 7.0 and OpenGL 1.2, with no Vulkan support. These are legacy APIs that lack modern features like shader model 3.0 or later, tessellation, or compute shaders.

The feature set is thus confined to fixed-function transformation and lighting (T&L) as was standard for DirectX 7.0, though the fact pack does not explicitly confirm T&L hardware. The single VGA display output means no multi-monitor support and no digital connectivity. The AGP 4x bus interface provides a theoretical peak transfer rate that is far below PCIe generations, but this is consistent with the card’s release date. The absence of any shading unit count further indicates that the card relies on fixed-function pixel processing, not programmable shaders.

How It Compares

The `nearestRivals` array is empty, so no direct competitor comparisons with names, scores, or deltaPct values are available. The only contextual comparison is the percentile rank of 50, which places it at the median of all GPUs in the database. This implies that half of all historical GPUs perform better and half perform worse. Given the card’s low memory bandwidth and small VRAM, the 50th percentile likely reflects its position among other early-2000s entry-level cards, where it was a mid-pack performer.

The predecessor is listed as the Quadro Celsius, and the successor is the Quadro4 Celcius. Without scores for either, no numerical delta can be stated. Qualitatively, the Quadro2 MXR represents an incremental step from the Celsius generation, but the successor Quadro4 Celcius would presumably offer architectural improvements — though the fact pack provides no specifics. The production status of end-of-life confirms that no ongoing support or driver updates are expected. In the absence of rival data, the only verifiable comparison is against the broader GPU population, where the card sits at the exact median.

Memory Subsystem

The memory configuration consists of 32 MB of SDR (single data rate) memory on a 128-bit bus, running at 183 MHz. This yields a bandwidth of 2.928 GB/s. The 128-bit bus width is a key attribute: it allows twice the data transfer per clock compared to a 64-bit bus, but the SDR type means only one data transfer per clock cycle, unlike DDR which would double that. The 2.928 GB/s bandwidth is modest by any standard, and it directly limits performance at high resolutions.

For high-resolution workloads, the 32 MB capacity is the more pressing constraint. A 1920x1080 framebuffer at 32 bits per pixel requires approximately 8.3 MB, leaving only about 23.7 MB for textures and geometry — this is insufficient for modern games or complex CAD models. The fact pack does not list any resolution-specific benchmarks, but the math is clear from the memory size. The 2.928 GB/s bandwidth also means that even if the framebuffer fit, texture streaming would bottleneck. The SDR type further compounds this, as it lacks the prefetch and burst efficiencies of later memory types. This subsystem is adequate for 800x600 or 1024x768 at low color depths, but the data suggests it will saturate quickly with any 3D acceleration.

Q: Is this card suitable for modern gaming?

A: No. With only 32 MB of SDR memory, 2.928 GB/s bandwidth, and DirectX 7.0 support, it cannot handle modern game requirements. Its 50th percentile ranking indicates it is mid-pack among all historical GPUs, but that is a relative measure against other old hardware.

Q: What power connector does the Quadro2 MXR require?

A: It requires no power connectors. The fact pack lists the power connectors as "None" and suggests a 200 W PSU.

Power and Cooling

The Quadro2 MXR has no listed TDP in the fact pack, so thermal output cannot be quantified numerically. However, the suggested PSU is 200 W, which is a low figure indicating modest power consumption. The card is single-slot in design, which is consistent with a low-profile, low-power workstation card. It uses no power connectors, drawing all power from the AGP 4x slot itself.

Cooling requirements are minimal given the 180 nm process and low complexity — 20 million transistors on 64 mm². The absence of any power connector suggests that a passive heatsink or a small active fan would suffice, though the fact pack does not specify the cooling solution. The single-slot width means it occupies only one expansion slot. The 200 W PSU recommendation is a system-level figure, not a card-specific draw, and it implies that the entire system should have at least that capacity. The card’s end-of-life status means no future driver updates, but its low power requirements make it safe for installation in older systems with modest power supplies. The AGP 4x interface further limits power delivery compared to later AGP 8x or PCIe slots, reinforcing the low-consumption profile.
