About Matrox Millennium G450
The Matrox Millennium G450 is a legacy graphics card built on the Condor chip, using the G400 architecture and a 180 nm process from UMC. It contains 10 million transistors and is equipped with 32 MB of DDR memory on a 64-bit bus, providing a bandwidth of 2.656 GB/s. The card is end-of-life, occupies a single slot, and connects via PCI. It offers one DVI and one VGA output. This analysis relies solely on the facts provided.
Who Should Consider It
The data describes a card with very modest specifications. The pixel rate is 250.0 MPixel/s and the texture rate is 250.0 MTexel/s, with only 2 texture mapping units and 2 render output units. The memory size of 32 MB is small by any modern standard, and the 64-bit bus limits the effective bandwidth to 2.656 GB/s. These figures indicate that the Millennium G450 is suited only for basic 2D display output, legacy software, or as a secondary adapter in a system that requires a PCI video card with DVI and VGA connections.
Given the DirectX 6.0 support and the absence of OpenGL, the card cannot run most 3D applications written after the early 2000s. The 50th percentile ranking among all GPUs in the database suggests it sits at the median, but with an average benchmark score of 0, this ranking is not supported by any measured performance. For users who need a simple, low-resolution display adapter for office tasks, web browsing, or connecting a secondary monitor to an older PCI-based system, the card’s specifications are sufficient. However, for any gaming or graphics-intensive workload, the 32 MB memory and limited fill rates will quickly become a bottleneck.
The card’s production status is end-of-life, meaning it is no longer manufactured. Prospective users should treat it as a vintage or specialty item. The single-slot form factor and lack of power connectors make installation straightforward in almost any chassis, but the PCI interface limits compatibility with modern motherboards that may no longer include such slots.
Ray Tracing and Feature Set
The FACT PACK lists no ray tracing cores and no tensor cores, so the card offers no hardware acceleration for ray tracing or AI-based features. The API support is minimal: DirectX 6.0 is the highest DirectX version, and OpenGL is listed as “None.” Vulkan support is not specified, which effectively means the card cannot run any Vulkan-based applications. The G400 architecture is a legacy design, and the feature set is confined to the capabilities of that era.
The memory operates at 166 MHz with an effective data rate of 332 Mbps (as stated). The DDR type is notable, but the 64-bit bus width limits the practical bandwidth to 2.656 GB/s. The pixel and texture rates are identical at 250.0 MPixel/s and 250.0 MTexel/s, indicating a balanced fill-rate design for its time. The card has 2 TMUs and 2 ROPs, which are typical for a low-end product of that generation. There are no hardware features for modern rendering techniques, and the absence of OpenGL support means that even legacy OpenGL titles will not run.
How It Compares
The provided data contains no nearestRivals entries, so a direct comparison to specific competitor products is impossible. The only positional metric is the percentileVsAllGpus value of 50, which places the card at the median of the GPU database. However, because the average benchmark score is 0, this percentile likely reflects a specification-based ranking rather than any measured performance. Without rival names, scores, or deltaPct values, no meaningful comparative analysis can be performed. The card’s position relative to other GPUs remains indeterminate, and any attempt to infer superiority or inferiority would be unsupported by the data.
The lack of benchmark data also means that the card’s real-world performance cannot be quantified. The theoretical pixel rate and texture rate are provided, but they do not translate into a measurable advantage over any other product. The 50th percentile is a neutral indicator, but it carries no weight without accompanying scores. In summary, the data does not permit a comparison against any rival, and this section must remain limited to that observation.

Benchmark Performance
The FACT PACK lists an average benchmark score of 0 and a percentile of 50, but no individual benchmark results are provided. This means the card’s performance cannot be evaluated in any specific workload. The theoretical specifications offer some insight: the pixel rate of 250.0 MPixel/s and texture rate of 250.0 MTexel/s are equal, suggesting that the card is not biased toward either pixel or texture throughput. The memory bandwidth of 2.656 GB/s, derived from a 64-bit bus and 166 MHz DDR memory, is a hard limit on data transfer. With 32 MB of memory, the card can hold only a small amount of texture data, which will affect any 3D application.
Because no rival scores or deltaPct values are available, the card’s performance relative to other GPUs cannot be stated. The 50th percentile ranking is the only comparative figure, but it is not tied to any measured score. The average benchmark score of 0 likely indicates that no benchmarks were executed, rather than a true zero performance. Therefore, any claim about the card’s speed or capability must be based solely on its theoretical fill rates and memory characteristics. The data shows that the card is a low-end, legacy product, but without benchmarks, its exact standing remains unknown.
Power and Cooling
The card is single-slot, with a length of 150 mm (5.9 inches). It has no power connectors, meaning it draws all power from the PCI slot. The suggested power supply is 200 W, which is a modest requirement. The TDP is not provided, but the absence of auxiliary power connectors and the single-slot design indicate a low-power device. The memory clock is 166 MHz, with an effective data rate of 332 Mbps (as listed). The card uses a 180 nm process and contains 10 million transistors, which are small numbers by modern standards.
The cooling solution is not specified, but the low power draw likely allows for passive cooling or a small, quiet fan. The single-slot form factor ensures compatibility with most systems, and the lack of power connectors simplifies installation. The 200 W PSU recommendation is easily met by most desktop power supplies, even older ones. The card’s dimensions are compact, making it suitable for small chassis or as a secondary display adapter. Overall, the power and cooling requirements are minimal, aligning with the card’s position as a basic, low-consumption product.
