Matrox Millennium G450 LP

The Matrox Millennium G450 LP is an end-of-life graphics card built around the Condor chip, fabricated by UMC on a 180 nm process with 10 million transistors. It connects via AGP 4x, outputs to a single DVI port, and the database records no benchmark scores for it — an average score of 0 — while its percentile rank against all GPUs sits at 50.

Benchmark Performance

The most striking fact in the data is the complete absence of benchmark results. The average benchmark score for the Millennium G450 LP is 0, and the benchmarks array is empty. This means no workload in the database has produced a score for this hardware. Its percentile rank of 50 among all GPUs is therefore a statistical artifact: the card occupies the exact midpoint of the database distribution, but that position is driven by the lack of recorded data, not by a measured performance level.

What the FACT PACK does provide are the fixed-function throughput rates. The pixel rate is 250.0 MPixel/s, and the texture rate is 250.0 MTexel/s, both enabled by 2 texture mapping units and 2 raster operation units. These are modest figures by any standard. A pixel rate of 250.0 MPixel/s means the card can write 250 million pixels per second under ideal conditions; the texture rate matches it exactly, indicating a balanced design where each TMU and ROP operates at the same clock. The memory clock is 166 MHz, with DDR signalling producing an effective 332 Mbps per pin, feeding a 64-bit bus for a total bandwidth of 2.656 GB/s.

The API support is the clearest indicator of the card's intended role. DirectX 6.0 is the only graphics API recorded; OpenGL is listed as None. That combination means the card cannot execute any OpenGL workload, and DirectX titles are limited to the feature set of version 6.0. In practical terms, this restricts the card to 2D desktop acceleration and early 3D games that shipped with DirectX 6.0 paths.

The 50th percentile rank, combined with the zero score, tells a specific story. In a database where many GPUs have measured results, a card with no scores is placed at the median — but this is not a competitive position. It is a placeholder. The theoretical rates of 250.0 MPixel/s and 250.0 MTexel/s are the only performance indicators available, and they suggest a card that was designed for a niche: low-power, single-slot, 2D-focused acceleration in legacy office and workstation systems.

Who Should Consider It

The Millennium G450 LP is not a card for modern 3D workloads. The 32 MB DDR memory capacity and 2.656 GB/s bandwidth are the hard limits: any application that needs large framebuffers or heavy texture streaming will exceed the memory or saturate the bus. The card's single DVI output and AGP 4x interface define its connectivity, and the absence of power connectors, combined with a suggested PSU of 200 W, means it draws very little power.

The physical dimensions matter for compatibility. The card is 168 mm (6.6 inches) long and occupies a single slot. That makes it suitable for compact chassis, especially older systems designed around AGP 4x slots. The lack of power connectors removes any concern about PSU cable routing, and the 200 W suggested PSU is well within the range of typical office power supplies from the card's era.

For users maintaining vintage systems, the card offers a functional path to a digital DVI display. The DirectX 6.0 support means early 3D games from that API generation can run, but the 250.0 MTexel/s texture rate and 2.656 GB/s bandwidth will constrain settings. The 32 MB memory is the primary limitation: textures must fit within that footprint, and high color depths will consume it quickly. The 50th percentile rank in the database is not a recommendation; it is a reflection of the card's unmeasured status. Buyers should consider this card only for its intended legacy role: a low-power, single-slot AGP card with a DVI output for a vintage desktop.

Memory Subsystem

The memory subsystem is the defining characteristic of this card. It consists of 32 MB of DDR memory on a 64-bit bus, clocked at 166 MHz with an effective data rate of 332 Mbps per pin. The total bandwidth is 2.656 GB/s.

That bandwidth figure is the single most important constraint on performance. To put it in context, the pixel rate of 250.0 MPixel/s requires a certain minimum bandwidth just to write framebuffer data; at a modest color depth, 2.656 GB/s is sufficient, but as color depth increases or textures are added, the bandwidth becomes the bottleneck. The 64-bit bus width means the card moves data in relatively small chunks per clock cycle, and the 166 MHz clock limits how quickly those chunks are transferred. The DDR type doubles the data rate per clock, which is why the effective rate is 332 Mbps per pin — double the 166 MHz clock.

The 32 MB capacity is small by any modern standard, but it was a deliberate choice for a card of this class. The framebuffer must share that 32 MB with texture storage, so a 3D scene at a high resolution and color depth will quickly exhaust available memory. For 2D desktop work, 32 MB is ample; for 3D, it is a hard ceiling. The absence of power connectors and the 200 W suggested PSU confirm that the memory subsystem was engineered for minimal power draw, not for maximum throughput.

For high-resolution displays, the implications are clear. The 2.656 GB/s bandwidth and 32 MB capacity limit the card to modest resolutions and color depths. The single DVI output supports a digital connection, but the memory subsystem does not have the headroom to drive large framebuffers at high refresh rates. Users should expect to run conservative settings, particularly in any 3D application, and should treat the memory subsystem as the primary bottleneck — not the pixel rate or texture rate, which are comparatively higher.

A: The average benchmark score is 0, with no recorded benchmarks, and the card sits at the 50th percentile of all GPUs in the database.

How It Compares

The nearestRivals field in the FACT PACK is empty, which means the database holds no direct competitor records for the Millennium G450 LP. This absence is consistent with the card's unmeasured status: with an average benchmark score of 0 and no recorded workloads, there are no comparative data points to place alongside it. The 50th percentile rank is therefore a statement about data availability, not about performance.

In the absence of named rivals, the card's position must be described by its internal specifications. The 250.0 MPixel/s pixel rate and 250.0 MTexel/s texture rate place it in a class of 2D-oriented accelerators, while the 2.656 GB/s bandwidth and 32 MB capacity define its memory ceiling. Against the broader database, the 50th percentile suggests a median position in the distribution — but that median is an artifact of the zero-score record, not a measured outcome.

The card's end-of-life status and AGP 4x interface further separate it from any modern GPU in the database. With no power connectors and a 200 W suggested PSU, it occupies a niche of low-power legacy systems. The single DVI output and DirectX 6.0 support complete the picture: this is a card for a specific, dated use case, and the database reflects that by recording no rivals and no scores for it. The 10 million transistors on a 180 nm process at UMC place it firmly in an earlier manufacturing era, and the 168 mm length and single-slot design are the physical attributes that define its compatibility envelope.
