ATI Radeon Xpress 1250 Mobile IGP

The ATI Radeon Xpress 1250 Mobile IGP is a legacy integrated graphics processor from AMD, built on the 80 nm process node with the RS690 chip. It is based on the R400 architecture and belongs to the Radeon IGP (Xpress 1200 Mobile) generation. The part is designated as end-of-life, with its production status confirmed as discontinued, and it was succeeded by the TeraScale IGP. The GPU carries 120 million transistors on a 73 mm² die, resulting in a transistor density of 1.6M per mm². It operates with 4 texture mapping units and 4 render output units, delivering a pixel rate of 1.600 GPixel/s and a texture rate of 1.600 GTexel/s. The memory subsystem is entirely system-shared, meaning both the size, type, and bus width are dependent on the host system's RAM, with bandwidth labeled as system dependent. The bus interface is PCIe 1.0 x16, and the slot width is classified as IGP, with no power connectors required. Display outputs are portable device dependent, reflecting its mobile IGP nature.

Who Should Consider It

The Radeon Xpress 1250 Mobile IGP is positioned for users who require basic graphical output from a mobile platform without any expectation of gaming or GPU-accelerated workloads. Given its benchmark scores are effectively zero and it holds the 50th percentile among all GPUs, this part is strictly for legacy systems where display output is the sole requirement. The hardware supports DirectX 9.0b (9_2) and OpenGL 2.0, which limits it to software from the early-to-mid 2000s era. For resolutions typical of that period, such as 1024x768 or 1280x800 on a laptop panel, the integrated graphics can handle 2D desktop environments, office applications, and video playback of standard-definition content, though the system-dependent memory bandwidth will directly influence any performance.

Users considering this IGP for gaming should note that its API support caps at DirectX 9.0b, which excludes many later DirectX 9 titles that require the 9_0c or 9_0ex feature levels. The 4 ROPs and 4 TMUs are minimal by any standard, and the 1.600 GPixel/s fill rate indicates that even modest 3D scenes from that era will strain the hardware. The part is not suitable for any resolution above the native panel of the laptop it resides in, and even then, settings must be at their lowest. For productivity tasks, the lack of dedicated memory means the system RAM is shared, so performance will degrade if the host system has limited memory capacity. The 80 nm process node and 120 million transistor count are indicative of a design from a specific era, and the R400 architecture offers no modern features such as hardware video decoding or compute shaders.

The absence of any benchmark scores in the data suggests that this GPU was never a performance contender, even at launch. The percentile ranking of 50, which is the median, is misleading in this context because the benchmark pool likely includes many similarly weak integrated parts. The primary use case for this hardware is a basic frame buffer for a legacy laptop, where the user needs to run an operating system with a graphical interface and nothing more. It is not for anyone seeking to play games, render 3D content, or accelerate any modern application. The system-dependent nature of the memory bandwidth means that a laptop with faster RAM will yield proportionally better performance, but the ceiling remains extraordinarily low.

How It Compares

The Radeon Xpress 1250 Mobile IGP has no nearest rivals listed in the data, which positions it as a standalone entry in the benchmark database with no direct comparisons available. The nearestRivals array is empty, meaning there are no competitor scores, names, or deltaPct values to reference. This absence of comparison data indicates that the GPU is either too old, too obscure, or too weak to warrant direct benchmarking against other parts. The 50th percentile ranking is the only positional metric available, and it places the IGP exactly in the middle of all GPUs in the database, though this is likely skewed by the inclusion of many other low-end integrated parts.

Without rival data, the analysis must rely on the architectural specifications to infer relative position. The R400 architecture with 4 TMUs and 4 ROPs places it in the same class as other early integrated graphics solutions from the mid-2000s, but no specific names or scores are available for comparison. The 1.600 GTexel/s texture rate is a fixed hardware limit, and the 1.600 GPixel/s pixel rate is similarly fixed, which means the GPU's throughput is bound by these figures regardless of the system memory speed. The lack of any benchmark scores in the benchmarks array further confirms that this part was never subjected to standardized testing, likely because it was not intended for any measurable performance workload.

The successor, TeraScale IGP, represents the next generation of integrated graphics from AMD, but no performance delta is provided. The transition from R400 to TeraScale architecture was a major shift in AMD's GPU design philosophy, but the data does not quantify the improvement. The empty nearestRivals field is a notable gap in the dataset, as it prevents any direct comparison to contemporaneous parts from NVIDIA or Intel. Users seeking a comparative analysis must rely on the raw specifications alone, which show a very limited part with no distinguishing features beyond its integrated nature and system-shared memory.

Ray Tracing and Feature Set

The Radeon Xpress 1250 Mobile IGP does not include any ray tracing cores or tensor cores, as both fields are marked null. This is expected for an IGP from 2007, as ray tracing hardware did not exist in consumer GPUs at that time. The feature set is limited to the R400 architecture's baseline capabilities, which include support for DirectX 9.0b (9_2) and OpenGL 2.0. There is no Vulkan support, and the API list is notably sparse, reflecting the hardware's age and limited scope. The DirectX 9.0b support means that shader model 2.0 is the maximum available, which restricts the GPU to older game engines and effects.

The lack of tensor cores means no machine learning or AI acceleration is present, and the absence of RT cores means no hardware-accelerated ray tracing. The 4 TMUs handle texture filtering and address calculations, while the 4 ROPs manage pixel output and blending operations. The 1.600 GPixel/s pixel rate is the ceiling for fill-rate-dependent operations, and the 1.600 GTexel/s texture rate is the ceiling for texture fetches. These are fixed hardware limits that cannot be exceeded regardless of the system memory configuration. The system-shared memory architecture means that the GPU has no dedicated VRAM, and the bandwidth is entirely dependent on the host laptop's RAM speed and bus width.

The API support for OpenGL 2.0 allows for basic 3D applications from that era, but modern OpenGL features such as geometry shaders, tessellation, and compute shaders are not available. The DirectX 9.0b specification predates the 9_0c update, which added shader model 3.0 support, so the GPU cannot run titles that require that feature level. The display outputs are portable device dependent, which means the actual connectors and supported resolutions vary by laptop model, but the GPU core itself provides no advanced display features such as multi-monitor support or hardware video scaling. The R400 architecture is a fixed-function design with no programmable compute units beyond the limited pixel and vertex shader units implied by the DirectX 9.0b support.

Power and Cooling

The TDP for the Radeon Xpress 1250 Mobile IGP is not listed in the data, which is typical for an integrated graphics processor that shares the thermal envelope of the host laptop's CPU. The slot width is classified as IGP, indicating that it is soldered onto the motherboard and does not occupy an expansion slot. The power connectors field is marked as "None," meaning the GPU draws power solely from the motherboard's socket and does not require any external PCIe power connectors. The suggested PSU field is also null, which is appropriate for an IGP that does not have a discrete power requirement.

Cooling requirements are minimal due to the integrated nature of the part. The 80 nm process node and 120 million transistors generate relatively low heat, and the 73 mm² die size is small, which aids in thermal dissipation. The absence of a TDP figure suggests that the thermal load is subsumed within the laptop's overall cooling solution, and no additional cooling is necessary beyond the system's existing fans or passive heat sinks. The system-shared memory means that the GPU does not have its own memory modules, reducing the overall component count and associated power draw.

The lack of a suggested PSU rating is notable because it confirms that this part is not intended for a desktop system with a discrete power supply. The PCIe 1.0 x16 bus interface is present for connecting to the host chipset, but the IGP designation means it is integrated into the northbridge or motherboard. The power connectors being "None" further reinforces that no external power delivery is required. For a laptop, the thermal and power characteristics are entirely managed by the platform, and the GPU's contribution to the overall power budget is negligible. The production status of end-of-life means that no new systems are being manufactured with this part, and replacement units are unavailable.
