UnknownMatrox Parhelia PCI Specifications
Matrox Parhelia PCI GPU Core
Shader units and compute resources
The Matrox Parhelia PCI 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 PCI Clock Speeds
GPU and memory frequencies
Clock speeds directly impact the Matrox Parhelia PCI'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 PCI by Unknown dynamically adjusts frequencies based on workload, temperature, and power limits to maximize performance while maintaining stability.
Unknown's Matrox Parhelia PCI Memory
VRAM capacity and bandwidth
VRAM (Video RAM) is dedicated memory for storing textures, frame buffers, and shader data. The Matrox Parhelia PCI'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 PCI Theoretical Performance
Compute and fill rates
Theoretical performance metrics provide a baseline for comparing the Matrox Parhelia PCI 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.

No benchmark data available for this GPU.
About Matrox Parhelia PCI
The Matrox Parhelia PCI is built around the Parhelia-512 chip on a 150 nm process at UMC. The die contains 80 million transistors across 174 mm², working out to a transistor density of 459.8K per square millimeter. The architecture and generation are both listed as Parhelia; the series and codename fields are null. The manufacturer is listed as Unknown, and no release date is given. The database entry is unusual because its benchmarks array is empty, its average benchmark score is 0, and its percentile against all GPUs is 50. Its nearestRivals array is also empty, so this page has no direct competitor scores to lean on.
How It Compares
The nearestRivals array in the FACT PACK is empty. That means there are no rival names, no rival scores, and no deltaPct values to report. The only relative number present is percentileVsAllGpus: 50, which places the card at the midpoint of the database’s GPU list. However, because the average benchmark score is 0 and the benchmarks list is empty, that percentile cannot be tied to any measured performance result.
The predecessor and successor fields are also null, so the entry does not place the Matrox Parhelia PCI in a product-line sequence. In this database, then, the card is an isolated entry. No per-rival paragraphs can be written because there are no rivals to compare against. The absence of comparison data is itself the main finding for this section.
Ray Tracing and Feature Set
The FACT PACK reports null values for rtCores and tensorCores. There is no ray tracing core count and no tensor core count in the data. The API support is listed as DirectX 8.1 and OpenGL 1.3; the Vulkan field is null. Those API levels define the feature set that software can expect.
The fixed-function pipeline is described by 16 texture mapping units and 4 render output units. The pixel rate is 800.0 MPixel/s, and the texture rate is 3.200 GTexel/s. Shading units are not listed; fp16 and fp32 throughput values are also null. So the entry does not define shader compute performance. What is quantifiable is a pipeline centered on texture and pixel throughput within the listed DirectX 8.1 and OpenGL 1.3 interface. Ray tracing and tensor acceleration are not part of the data.
Memory Subsystem
Memory capacity is 256 MB of DDR. The bus width is 64 bit, and the memory clock is 250 MHz with 500 Mbps effective. That yields a memory bandwidth of 4.000 GB/s. These are the only memory figures in the pack.
For high-resolution considerations, the bandwidth figure is the key resource. The pack does not include tested resolutions, so high-resolution behavior cannot be quantified from benchmark data. What can be said is that the memory subsystem is a 256 MB DDR framebuffer on a 64-bit datapath, with 4.000 GB/s as the total transfer envelope. The texture rate of 3.200 GTexel/s and the pixel rate of 800.0 MPixel/s are the main consumers of that bandwidth, though the pack does not describe how those workloads share the bus.
The 2x DVI display outputs mean the card is prepared for digital displays. The memory capacity and bandwidth, together with the pixel and texture rates, are the relevant numbers for evaluating any resolution-based workload.

Who Should Consider It
There are no benchmark scores in the entry, so recommendations cannot be grounded in measured game performance. The data instead points to a particular hardware profile: a single-slot PCI-X card with 2x DVI outputs, 256 MB DDR memory, a 64-bit bus, and the listed DirectX 8.1 and OpenGL 1.3 API support.
The pixel rate of 800.0 MPixel/s and texture rate of 3.200 GTexel/s are the only throughput figures available for estimating workload fit. The pack does not state which resolution or settings the card supports, so any recommendation must stop at saying that the card offers those specific fill rates. Users with PCI-X slots and DVI monitors are the audience suggested by the bus and display outputs. The "None" power connector entry and 200 W suggested PSU also indicate a card that does not rely on auxiliary power cabling, though the pack does not draw that conclusion itself.
Power and Cooling
The TDP field is null, so the FACT PACK does not quantify heat output. The slot width is single-slot, and the power connector field is "None". The suggested PSU is 200 W. The length of the card is 190 mm, or 7.5 inches.
No cooler design is described in the pack. The mechanical data available is limited to the single-slot form factor and the physical length. The "None" power connector entry means no auxiliary power cables are required according to the data. The lack of a TDP value leaves the actual thermal demand unspecified, but the 200 W suggested PSU is the only power-system requirement given.
Benchmark Performance
The benchmarks array is empty, and the average benchmark score is 0. The nearestRivals array is also empty, so there are no exact percentage deltas to analyze for this entry. The only comparison-style metric is percentileVsAllGpus: 50, which places the card at the midpoint of all GPUs in the database. Without any benchmark scores behind that percentile, it cannot be converted into a statement about relative speed.
The performance-oriented numbers that do exist are the architectural rates: 800.0 MPixel/s pixel rate and 3.200 GTexel/s texture rate. These describe the fixed-function pipeline directly. The absence of rival data means the Matrox Parhelia PCI cannot be positioned against neighboring products using deltas. Its database standing rests on the listed specifications rather than on measured results.
