UnknownMatrox Parhelia DL256 Specifications
Matrox Parhelia DL256 GPU Core
Shader units and compute resources
The Matrox Parhelia DL256 GPU core specifications define its raw processing power for graphics and compute workloads. Shading units (also called CUDA cores, stream processors, or execution units depending on manufacturer) handle the parallel calculations required for rendering. TMUs (Texture Mapping Units) process texture data, while ROPs (Render Output Units) handle final pixel output. Higher shader counts generally translate to better GPU benchmark performance, especially in demanding games and 3D applications.
Matrox Parhelia DL256 Clock Speeds
GPU and memory frequencies
Clock speeds directly impact the Matrox Parhelia DL256's performance in GPU benchmarks and real-world gaming. The base clock represents the minimum guaranteed frequency, while the boost clock indicates peak performance under optimal thermal conditions. Memory clock speed affects texture loading and frame buffer operations. The Matrox Parhelia DL256 by Unknown dynamically adjusts frequencies based on workload, temperature, and power limits to maximize performance while maintaining stability.
Unknown's Matrox Parhelia DL256 Memory
VRAM capacity and bandwidth
VRAM (Video RAM) is dedicated memory for storing textures, frame buffers, and shader data. The Matrox Parhelia DL256's memory capacity determines how well it handles high-resolution textures and multiple displays. Memory bandwidth, measured in GB/s, affects how quickly data moves between the GPU and VRAM. Higher bandwidth improves performance in memory-intensive scenarios like 4K gaming. The memory bus width and type (GDDR6, GDDR6X, HBM) significantly influence overall GPU benchmark scores.
Matrox Parhelia DL256 Theoretical Performance
Compute and fill rates
Theoretical performance metrics provide a baseline for comparing the Matrox Parhelia DL256 against other graphics cards. FP32 (single-precision) performance, measured in TFLOPS, indicates compute capability for gaming and general GPU workloads. FP64 (double-precision) matters for scientific computing. Pixel and texture fill rates determine how quickly the GPU can render complex scenes. While real-world GPU benchmark results depend on many factors, these specifications help predict relative performance levels.
Parhelia Architecture & Process
Manufacturing and design details
The Matrox Parhelia DL256 is built on Unknown's Parhelia architecture, which defines how the GPU processes graphics and compute workloads. The manufacturing process node affects power efficiency, thermal characteristics, and maximum clock speeds. Smaller process nodes pack more transistors into the same die area, enabling higher performance per watt. Understanding the architecture helps predict how the Matrox Parhelia DL256 will perform in GPU benchmarks compared to previous generations.
Unknown's Matrox Parhelia DL256 Power & Thermal
TDP and power requirements
Power specifications for the Matrox Parhelia DL256 determine PSU requirements and thermal management needs. TDP (Thermal Design Power) indicates the heat output under typical loads, guiding cooler selection. Power connector requirements ensure adequate power delivery for stable operation during demanding GPU benchmarks. The suggested PSU wattage accounts for the entire system, not just the graphics card. Efficient power delivery enables the Matrox Parhelia DL256 to maintain boost clocks without throttling.
Matrox Parhelia DL256 by Unknown Physical & Connectivity
Dimensions and outputs
Physical dimensions of the Matrox Parhelia DL256 are critical for case compatibility. Card length, height, and slot width determine whether it fits in your chassis. The PCIe interface version affects bandwidth for communication with the CPU. Display outputs define monitor connectivity options, with modern cards supporting multiple high-resolution displays simultaneously. Verify these specifications against your case and motherboard before purchasing to ensure a proper fit.

About Matrox Parhelia DL256
The Matrox Parhelia DL256 is an end-of-life graphics card in the Parhelia generation, built around the Parhelia-512 chip. The manufacturer field is Unknown, and the architecture is listed as Parhelia. UMC fabricates the chip on a 150 nm process, with 80 million transistors on a 174 mm² die, resulting in a transistor density of 459.8K per mm². The memory subsystem consists of 256 MB of DDR on a 64-bit bus, clocked at 250 MHz with a 500 Mbps effective data rate and 4.000 GB/s of bandwidth. The fixed-function pipeline is 16 TMUs and 4 ROPs, with a texture rate of 3.200 GTexel/s and a pixel rate of 800.0 MPixel/s. The card is single-slot, 190 mm (7.5 inches) long, uses a PCI-X bus interface, has no power connectors, and lists a 200 W suggested PSU. Display output is provided through 2x LFH60 connectors. API support covers DirectX 8.1 and OpenGL 1.3; no Vulkan version is listed. The spec table records no series, no codename, no release date, and no benchmark scores.
How It Compares
The nearestRivals array in the FACT PACK is empty. There are therefore no rival GPU names, scores, or deltaPct values available for comparison in this entry. The only positional field is percentileVsAllGpus, which is 50. That places the Matrox Parhelia DL256 at the midpoint of the database’s GPU population. However, the benchmarks array is also empty and the avgBenchmarkScore field is 0, so this percentile is not backed by any listed application or synthetic scores. Without nearestRivals entries, no percentage lead or deficit can be stated against any specific competitor.
Ray Tracing and Feature Set
The RT core and tensor core fields are both null in the provided data. As a result, the dataset does not quantify hardware ray tracing acceleration or tensor-based processing for this card. The feature set is instead defined by fixed-function throughput, API support, and board-level capabilities. The Parhelia-512 chip belongs to the Parhelia generation, and the architecture is also Parhelia. The listed API levels are DirectX 8.1 and OpenGL 1.3, with no Vulkan version recorded. The 16 TMUs deliver a texture rate of 3.200 GTexel/s, while the 4 ROPs deliver a pixel rate of 800.0 MPixel/s. No shading unit count is listed, and no FP32 or FP16 throughput values are listed.
The card’s display feature set is two LFH60 connectors. It is a single-slot board and uses a PCI-X bus interface. Power delivery requires no auxiliary power connectors, and the suggested PSU is 200 W. Because no RT core or tensor core counts are present in the data, the product cannot be positioned as a hardware ray tracing or tensor-accelerated part in this database.
Memory Subsystem
The memory specification is 256 MB of DDR memory on a 64-bit bus. The memory clock is 250 MHz, with an effective data rate of 500 Mbps. This produces a total bandwidth of 4.000 GB/s. That bandwidth figure is the full data path between memory and the 16 TMUs and 4 ROPs. For high-resolution workloads, the 256 MB framebuffer is the available capacity, and the 64-bit bus is the interface responsible for moving pixel and texture data into and out of that framebuffer.
The 4.000 GB/s bandwidth is a concrete limit for texture sampling and pixel writes, even though the database does not provide benchmark results showing how that limit affects real-world performance. The memory timing data is limited to 250 MHz and 500 Mbps effective; no other clock information is supplied in the FACT PACK. The combination of 256 MB VPU memory, a 64-bit data path, and 4.000 GB/s bandwidth defines the entire memory subsystem profile for this card.

Benchmark Performance
The benchmarks array is empty, so there are no application scores, synthetic test scores, or frame-rate results to analyze. The avgBenchmarkScore field is 0, and the nearestRivals array is empty. Consequently, the exact percentage deltas that this database typically uses to express performance differences cannot be computed for the Matrox Parhelia DL256.
The only quantitative performance indicators in the FACT PACK are fixed-function rates: 800.0 MPixel/s pixel rate and 3.200 GTexel/s texture rate. The 4 ROPs correspond to the pixel rate, while the 16 TMUs correspond to the texture rate. These values characterize theoretical throughput, not measured benchmark performance. The 4.000 GB/s memory bandwidth is the associated data limit for those units during memory-intensive rendering.
The percentileVsAllGpus value is 50, placing the card at the midpoint of the database’s GPU list. Because the benchmark scores that usually support a percentile are absent, this position is an isolated data point. No statement of the form “X% faster than a rival” is supported by the available data, because no deltaPct values exist. The FACT PACK does not contain enough benchmark material to rank this card above or below any other named GPU.
