ATI Radeon Xpress 1150 Mobile IGP

The ATI Radeon Xpress 1150 Mobile IGP is an integrated graphics processor from AMD, built on the RS485 chip with the R300 architecture. Released on May 22, 2006, it is now end-of-life and occupies the 50th percentile in the benchmark database, with an average benchmark score of 0. This places it exactly at the median of all GPUs, though the zero score indicates that no performance data has been recorded for this part. As an IGP, it is designed to be embedded in a mobile chipset, sharing system memory rather than using dedicated VRAM.

How It Compares

The data pack lists no nearest rivals for this GPU, meaning direct comparative scores against other parts are unavailable. However, its percentile rank of 50 provides a reference point: it sits at the midpoint of the entire GPU database, suggesting a typical performance level for an integrated solution of its generation. Without rival scores or delta percentages, we cannot quantify its standing relative to specific competitors. The only other positional reference is its successor, the TeraScale IGP, which indicates that this part belongs to an older architectural line. Given that it is an end-of-life mobile IGP, its performance is best understood in the context of its own specifications rather than head-to-head comparisons.

Ray Tracing and Feature Set

The Radeon Xpress 1150 Mobile IGP has no ray tracing cores and no tensor cores, as those fields are null in the data. This means it lacks hardware acceleration for ray-traced lighting and AI-based features. Its API support is limited to DirectX 9.0 and OpenGL 2.0, with no Vulkan support. These are legacy APIs that were standard in the mid-2000s but are now considered outdated. The absence of modern API support precludes compatibility with current graphics workloads, including recent games and compute applications. The feature set is further constrained by its 2 texture mapping units (TMUs) and 2 render output units (ROPs), which are modest numbers for even basic 3D rendering. The pixel fill rate is 800.0 MPixel/s and the texture fill rate is 800.0 MTexel/s, indicating that the GPU can process 800 million pixels and 800 million texels per second. These figures are low by modern standards but were acceptable for entry-level mobile graphics in 2006.

Who Should Consider It

Given its specifications, the Radeon Xpress 1150 Mobile IGP is suitable only for very light graphical tasks. The pixel and texture fill rates of 800 MPixel/s and 800 MTexel/s, respectively, are sufficient for 2D desktop environments, basic video playback, and simple 3D applications from its era. Users running legacy software that targets DirectX 9.0 or OpenGL 2.0 may find it functional, but it will struggle with any modern game or GPU-accelerated application. The 50th percentile rank, while indicating a median position, does not reflect actual performance because the average benchmark score is 0. This suggests that no reliable performance data exists, so potential users should rely on the raw specifications. The system-shared memory design means that performance is highly dependent on the host system's RAM speed and capacity, making it unpredictable. This IGP is best considered for vintage systems or as a fallback display output on old laptops, not for any serious 3D workload.

FAQ

Q: What is the memory configuration of the Radeon Xpress 1150 Mobile IGP?

A: The memory size, type, and bus width are all listed as "System Shared," meaning the GPU uses a portion of the system's main RAM. The memory bandwidth is "System Dependent," so it varies based on the host platform's memory controller and RAM speed.

Q: Which graphics APIs does this GPU support?

A: It supports DirectX 9.0 and OpenGL 2.0. It does not support Vulkan or any later API versions.

Q: Does the Radeon Xpress 1150 Mobile IGP have ray tracing or tensor cores?

A: No. The data lists both ray tracing cores and tensor cores as null, indicating they are absent.

Q: What is the process node and die size?

A: It is fabricated on a 110 nm process at TSMC, with a die size of 73 mm².

Q: What is the pixel and texture fill rate?

A: The pixel fill rate is 800.0 MPixel/s, and the texture fill rate is 800.0 MTexel/s.

Q: Is this GPU still in production?

A: No, its production status is "End-of-life." It was released on May 22, 2006, and has been succeeded by the TeraScale IGP.

Benchmark Performance

The benchmark data for the Radeon Xpress 1150 Mobile IGP is sparse: the average benchmark score is 0, and the percentile rank is 50. A score of 0 typically indicates that no benchmarks were successfully recorded or that the GPU was not tested under the database's methodology. The 50th percentile rank, however, places it at the exact median of all GPUs in the database. This is an unusual combination—a median position with zero measured performance suggests that the rank is derived from the absence of data rather than from competitive scores. Without any rival scores or delta percentages, we cannot perform a comparative analysis. The only quantitative performance indicators are the fill rates: 800 MPixel/s and 800 MTexel/s. These numbers, when interpreted against typical workloads, imply that the GPU can handle simple 2D compositing and basic 3D scenes with low polygon counts, but it will be a bottleneck for anything more demanding. The lack of recorded benchmarks further reinforces that this IGP is not intended for performance-critical applications.

Memory Subsystem

The Radeon Xpress 1150 Mobile IGP relies entirely on system memory, with no dedicated VRAM. The memory size, type, and bus width are all designated as "System Shared," meaning the GPU dynamically allocates a portion of the main system RAM for frame buffer and texture storage. The bandwidth is "System Dependent," so actual throughput is determined by the host platform's memory architecture, such as single-channel versus dual-channel configurations and RAM speed. This design is typical for integrated graphics, as it reduces cost and power consumption but introduces performance variability. For high-resolution display output, the shared memory approach can lead to contention between the CPU and GPU, especially if the system has limited RAM. The 2 ROPs and 2 TMUs further limit the memory subsystem's ability to push pixels and textures efficiently. In practice, this IGP is best suited to low resolutions and modest refresh rates, as the system-dependent bandwidth will likely become a bottleneck at higher settings.

Power and Cooling

The TDP for the Radeon Xpress 1150 Mobile IGP is not specified in the data, and no suggested PSU is listed. The power connectors field is "None," which is expected for an integrated GPU that draws power from the motherboard rather than a dedicated PCIe power cable. The slot width is listed as "IGP," confirming that it is not a discrete expansion card but an integrated component of a chipset. This means it does not require its own cooling solution; instead, it relies on the laptop's or motherboard's existing thermal management. The absence of a TDP value suggests that AMD did not publicly rate the power consumption, but given the 110 nm process and the low fill rates, it is reasonable to infer that power draw is minimal. The GPU's end-of-life status and mobile orientation further imply that it was designed for energy efficiency rather than peak performance. Users should ensure that the host system has adequate cooling for the entire chipset, as the IGP shares thermal capacity with the northbridge and other components. No additional power supply requirements are necessary beyond what the motherboard provides.
