AMDATI Mobility Radeon X1900 Specifications
ATI Mobility Radeon X1900 GPU Core
Shader units and compute resources
The ATI Mobility Radeon X1900 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.
ATI Mobility Radeon X1900 Clock Speeds
GPU and memory frequencies
Clock speeds directly impact the ATI Mobility Radeon X1900'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 ATI Mobility Radeon X1900 by AMD dynamically adjusts frequencies based on workload, temperature, and power limits to maximize performance while maintaining stability.
AMD's ATI Mobility Radeon X1900 Memory
VRAM capacity and bandwidth
VRAM (Video RAM) is dedicated memory for storing textures, frame buffers, and shader data. The ATI Mobility Radeon X1900'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.
ATI Mobility Radeon X1900 Theoretical Performance
Compute and fill rates
Theoretical performance metrics provide a baseline for comparing the ATI Mobility Radeon X1900 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.

About ATI Mobility Radeon X1900
The ATI Mobility Radeon X1900 is an AMD mobile graphics processor built around the M68 chip, using the Ultra-Threaded SE architecture and belonging to the M6x (Mobility X1) generation. It was released on 2007-01-10 and is listed as end-of-life. The chip is fabricated by TSMC on an 80 nm process with 312 million transistors, a 230 mm² die size, and a transistor density of 1.4M / mm². No series or codename is recorded in the database, so the product is identified primarily by its marketing name, chip designation, and generation label.
Benchmark Performance
The benchmark data for this entry is effectively empty. The average benchmark score is 0, the percentileVsAllGpus field is 50, and the nearestRivals array contains no entries. Because there are no nearest rivals, there are no deltaPct values to compare, and no exact percentage deltas can be presented. The 50th percentile field places the product at the midpoint of the database’s all-GPU distribution, but with an average benchmark score of 0, no measured sample runs lie behind that placement. It is a categorical position rather than a value derived from observed frame-time or score data.
Without sampled benchmark scores, the fixed-function specifications provide the only measurable performance context. The part has 12 texture mapping units and 12 ROPs. Its texture fill rate is 4.800 GTexel/s, and its pixel fill rate is 4.800 GPixel/s. These rates are identical, indicating a balanced relationship between texture processing and pixel output. That balance is plausible for the DirectX 9.0c (9_3) workload scope listed in the API data, but the benchmark section itself does not verify how that balance translates into application performance.
The data sheet also lacks FP32 and FP16 values, so general-purpose compute throughput cannot be quantified from this record. The manufacturing context is present: 312 million transistors on a 230 mm² die at 80 nm, with a density of 1.4M / mm². Those figures describe the scale of the chip, but without benchmark samples they do not become comparative speed numbers. In short, the database contains no direct score for this GPU, and any ordering against other GPUs cannot be established from nearestRivals data because that list is empty.
Memory Subsystem
The memory configuration is fully listed: 256 MB of GDDR3, a 256-bit bus, and a memory clock of 470 MHz with 940 Mbps effective data rate. These specifications produce a bandwidth figure of 30.08 GB/s. The bus width is the most substantial part of the memory design; the memory clock itself is moderate by the data presented, but the 256-bit interface provides a wide path for data movement.
High-resolution behavior is constrained by capacity as much as by bandwidth. The entire local frame buffer is 256 MB. Any workload requiring more than 256 MB of geometry, textures, render targets, or intermediate buffers cannot be contained within the listed memory capacity. The data does not include any additional memory-management features, so the capacity ceiling is simply 256 MB. Bandwidth of 30.08 GB/s determines how quickly data can cross the 256-bit interface; with a pixel fill rate of 4.800 GPixel/s, the memory transfer ceiling and pixel throughput are both specified, but the data does not show how those limits interact under a particular resolution or quality setting.
For high-resolution scenarios, the practical implication is that the 256 MB buffer leaves little room for large texture sets or high-depth render targets. The database does not provide resolution-specific benchmark evidence, so a precise verdict on 1080p or higher settings cannot be formed from this record. What can be said from the data is that the memory subsystem has a definitive size of 256 MB, a definitive bus width of 256 bit, and a definitive bandwidth of 30.08 GB/s, and that those three numbers define the upper boundary of local memory capacity and throughput.
Ray Tracing and Feature Set
Ray tracing and tensor hardware are not documented in this entry. The rtCores and tensorCores fields are null, so there are no core counts to report. Similarly, Vulkan support is null. The only listed graphics APIs are DirectX 9.0c (9_3) and OpenGL 2.1. Because no RT core or tensor core values are recorded, there is no basis in the data for claiming hardware-accelerated ray tracing or tensor-style machine-learning acceleration.
The API list is therefore the central feature-set statement: DirectX 9.0c (9_3) and OpenGL 2.1. DirectX 9.0c with the 9_3 feature level is the highest DirectX version noted for this product, and OpenGL 2.1 is the corresponding OpenGL support level. No Vulkan version is present in the specification record.
The architecture is labeled Ultra-Threaded SE, but the feature table does not associate that architecture with any additional API support beyond the DirectX and OpenGL values already listed. The data shows no Vulkan field value, no tensor core count, and no ray tracing core count. Therefore, any feature comparison must be restricted to the DirectX and OpenGL entries in the fact pack, with no documented hardware path for ray tracing or Vulkan workloads.

Who Should Consider It
The audience for this product is narrow, based on the available data. It is an end-of-life mobile GPU with no measured benchmark samples in the record. The only quantitative placement is the 50th percentile field, which is neutral in the database’s GPU distribution, but the average benchmark score of 0 means there is no performance sample behind that neutral position.
Software compatibility provides the clearest guidance. Applications that require DirectX 9.0c (9_3) or OpenGL 2.1 fit within the listed feature set. Applications that require Vulkan, documented ray tracing cores, or documented tensor cores do not have support for those features in the fact pack. The 256 MB memory capacity further narrows the field: workloads must fit within a 256 MB frame buffer to remain fully local. Settings or scenarios that exceed that capacity would be limited by the memory size, regardless of the 30.08 GB/s bandwidth or the 4.800 GTexel/s and 4.800 GPixel/s fill rates.
Users with older DirectX 9-era software that is not demanding on memory capacity could potentially match this specification. Users seeking high-resolution, high-texture, or modern-API workloads would not find support in the recorded data. Because the nearestRivals list is empty, there is no relative score data to recommend this card over another product. The decision must rest on the API compatibility, the 256 MB memory limit, and the balanced fill-rate specifications.
Power and Cooling
The power and cooling fields in the specification record are largely empty. No TDP value is listed. No suggested PSU is listed. No power connector information is listed. The slot width is given as MXM Module, and the bus interface is MXM-III. Because display outputs are marked as “Portable Device Dependent,” the product is integrated into a portable device rather than deployed as a standalone desktop card.
The absence of TDP data means no thermal envelope can be stated from the fact pack. The absence of a suggested PSU means no power-supply recommendation can be formed. The absence of power connector data means no connector requirement can be stated. The only manufacturing-related context for power and thermal considerations is the chip construction: 80 nm process, 312 million transistors, 230 mm² die size, and a density of 1.4M / mm². Those figures describe the physical chip, not a measured power draw or cooling solution.
The MXM Module form factor implies that cooling and power delivery are determined by the host device’s design rather than by a standalone card specification, but the data does not supply a cooler recommendation, a wattage figure, or a PSU requirement. As such, the power and cooling section of this entry is defined by what is not listed: no TDP, no PSU suggestion, and no connector details.
