No benchmark data available for this GPU.

About Matrox Millennium G450 x4 MMS

The Matrox Millennium G450 x4 MMS is an end-of-life PCI graphics card built around the Condor chip. It uses the G400 architecture and belongs to the G Series (G4xx) generation, manufactured at UMC on a 180 nm process with 10 million transistors. The series and codename fields are not populated, and the manufacturer is listed as Unknown. Released on 2002-06-18, the card is single-slot and measures 165 mm (6.5 inches) long, 97 mm (3.8 inches) tall, and 36 mm (1.4 inches) wide. No predecessor or successor is recorded, and the only clock value listed is the memory clock of 166 MHz with 332 Mbps effective.

Benchmark Performance

Benchmark performance cannot be quantified from the data in the usual way. The benchmarks array is empty, and the nearestRivals array is also empty. The average benchmark score is 0, and the percentileVsAllGpus field is 50. There are no exact deltaPct values to present against rival cards. Because no benchmark entries exist, the 0 average is not derived from any measured result. Without recorded scores, there is no measured basis for saying the card is faster or slower than any other product.

The only throughput numbers supplied are a pixel rate of 250.0 MPixel/s and a texture rate of 250.0 MTexel/s. These are generated with 2 TMUs and 2 ROPs. Because the two rates are identical, the card’s fillrate work is balanced between pixel and texture operations at the listed rates. With only 2 TMUs and 2 ROPs, the pipeline is narrow, but the data does not include enough detail to convert these rates into a comparative score. Shading-unit counts are not recorded, and FP32 and FP16 throughput fields are null. This means the data cannot characterize compute workloads beyond fixed-function fillrate.

The 50th-percentile placement is the single relative position in the data. But because the average benchmark score is 0 and no benchmark entries exist, that percentile cannot be anchored to a performance result. The card is best treated as unranked in terms of measured application performance. No base, boost, or game clock values are listed, so clock-based comparisons are also impossible.

Ray Tracing and Feature Set

The feature set is notable for what is absent. Ray tracing cores are not listed, and tensor cores are not listed. The card therefore has no recorded hardware paths for ray-traced rendering or tensor-based processing. API support consists solely of DirectX 6.0. OpenGL is recorded as None, and there is no Vulkan entry. This makes API compatibility extremely limited for any workload that expects OpenGL or Vulkan. DirectX 6.0 is the only documented API version, and no higher DirectX version appears in the data.

The display outputs are 2x DVI, which provides a dual-monitor connection path. The bus interface is PCI, so the card fits in a PCI slot. The data also leaves several feature-related fields empty: die size, transistor density, and shading units. The lack of Vulkan support and the OpenGL value of None means only DirectX 6.0 paths are available. This feature set points to basic display output rather than intensive 3D rendering. The chip is identified as Condor, the architecture as G400, and the generation as G Series (G4xx), but no further feature details are recorded.

How It Compares

The comparison data is empty. nearestRivals contains no entries, so no rival names, scores, or deltaPct values are available. This makes it impossible to write a per-rival comparison for this card. The only positional value is the 50th-percentile score against all GPUs, but that is not tied to any benchmark result because the average benchmark score is 0. In the absence of nearestRivals data, there is no evidence of a direct competitor. The G400 architecture and Condor chip are listed, but no other product is supplied as a reference point.

The empty rival list also means statements such as “ahead of” or “behind” another card are unsupported. The data does not include a predecessor or successor, so the product’s family position is not documented. The series and codename fields are also empty, which leaves the naming structure incomplete. As a result, the card stands without a measured anchor. No performance delta can be derived from an empty rival list.

Who Should Consider It

Who should consider this card depends on what the data actually says. There are no benchmark scores to guide resolution or settings choices, so any recommendation must come from memory capacity, bus interface, and display outputs. The card has 32 MB of DDR memory, a 64-bit bus, and 2.656 GB/s of bandwidth, with a pixel rate of 250.0 MPixel/s and a texture rate of 250.0 MTexel/s. Those numbers point to low-density graphics workloads, not high-resolution gaming. A 32 MB frame buffer limits the amount of image data that can be held on screen, and the 2.656 GB/s bandwidth constrains transfers to and from that memory.

The 2x DVI output configuration means the card can be considered for systems that need two DVI connections. The PCI bus interface limits the host to systems with PCI slots. The single-slot form factor and 165 mm length are practical installation facts. Users with a PCI-based system and modest display demands are the intended audience. The 50th-percentile ranking and 0 average score provide no evidence that the card can handle demanding settings. Therefore, the safest use is two-DVI output rather than high-detail 3D acceleration. The data does not support recommendations for high resolution or heavy texturing.

Memory Subsystem

Memory is one of the few areas with complete numbers. The card ships with 32 MB of DDR memory. The bus is 64 bits wide, and peak bandwidth is recorded as 2.656 GB/s. The memory clock is 166 MHz, with a 332 Mbps effective data rate. This effective rate is the only memory timing figure in the data, and bus width and capacity are the more important limits. With only 32 MB, the frame buffer is too small to hold large textures and high-depth buffers simultaneously. The 64-bit bus also limits how much data can move per clock.

For high-resolution output, the combination of capacity and bandwidth makes this a constrained part. The 2.656 GB/s bandwidth must also feed the 250.0 MTexel/s texture rate and 250.0 MPixel/s pixel rate. When the memory subsystem saturates, those fillrates cannot be sustained. The memory type is DDR, and the memory clock is 166 MHz, but no other memory characteristics are recorded. The memory subsystem is proportioned for a low-capacity, low-bandwidth workload.

Power and Cooling

The power and thermal data is sparse. TDP is not recorded, so no thermal design power is available. The suggested PSU is 200 W, which is the only power supply figure in the data. No power connectors are listed. The card is single-slot, and its physical dimensions are 165 mm (6.5 inches) long, 97 mm (3.8 inches) tall, and 36 mm (1.4 inches) wide. No cooler type or fan specification is included. The 200 W PSU recommendation is modest, and the absence of auxiliary power connectors indicates the card is not designed for high supplemental power draw.

The single-slot construction keeps installation simple. The data does not include temperature or noise figures, so thermal behavior cannot be assessed further. Builders should rely on the 200 W suggested PSU and the PCI slot constraint. The only recorded physical clearance values are the length, height, and width listed above, and the slot width is single-slot. Without a TDP value, there is no way to compare this card’s power requirement with other products. The power delivery path, based on the data, is limited to the PCI slot interface and whatever the 200 W PSU guidance implies.
