ATI Radeon Xpress 1100 Mobile IGP

The ATI Radeon Xpress 1100 Mobile IGP is an integrated graphics processor from AMD, built on the R300 architecture and manufactured at TSMC on a 110 nm process with a die size of 73 mm². It is end-of-life, with a successor in the TeraScale IGP line. The GPU uses system-shared memory, and its performance metrics are modest: a pixel rate of 600.0 MPixel/s, a texture rate of 600.0 MTexel/s, 2 texture mapping units, and 2 raster operation units. The bus interface is PCIe 1.0 x16, and it supports DirectX 9.0 and OpenGL 2.0. It sits at the 50th percentile among all GPUs in the database, with an average benchmark score of 0.

Memory Subsystem

The memory subsystem of the Radeon Xpress 1100 Mobile IGP is entirely system-shared. The VRAM size, memory type, and bus width are all listed as "System Shared", and the bandwidth is "System Dependent". This means the GPU does not have its own dedicated memory; instead, it borrows from the host system's main memory through the memory controller. Consequently, the available memory bandwidth is not a fixed specification but varies with the system's RAM type, speed, and configuration. For a mobile integrated processor, this is a common design to reduce cost and power draw, but it imposes significant limitations on graphics performance.

For high-resolution workloads, the lack of dedicated VRAM is a critical bottleneck. The GPU must access the same memory bus as the CPU, leading to contention and reduced effective bandwidth. The pixel rate of 600.0 MPixel/s indicates the maximum number of pixels that can be written per second. At high resolutions, the number of pixels to fill increases dramatically, and with a pixel rate this low, the GPU will struggle to maintain smooth frame rates even in simple 2D scenes. Similarly, the texture rate of 600.0 MTexel/s, combined with only 2 TMUs, means that texture-heavy rendering will be severely constrained. The 2 ROPs further limit the fill-rate capabilities, as each ROP handles pixel output operations. The overall memory subsystem is designed for basic desktop acceleration and light multimedia, not for high-resolution gaming or professional graphics. The system-dependent bandwidth also means that performance is highly sensitive to the system's memory configuration; faster system RAM can mitigate some bottlenecks, but the fixed pixel and texture rates remain hard limits.

How It Compares

The nearestRivals list for this GPU is empty in the database, so no direct competitor comparisons are available. However, the percentile ranking provides a relative position: at the 50th percentile, this GPU sits exactly in the middle of all GPUs tracked. This indicates that it outperforms half of the GPUs in the database and lags behind the other half. Given that the database includes a wide range of integrated and discrete GPUs, the median position suggests it is a low-end product, as many modern IGPs and all discrete GPUs would likely rank above it. Its successor, the TeraScale IGP, represents the next generation of AMD's integrated graphics, though no performance data is provided for that product. The production status is end-of-life, indicating that it has been discontinued and replaced. Without rival data, we cannot provide specific percentage deltas or performance comparisons, but the percentile alone places it as an average performer in the overall database, which is a meaningful signal given the broad spectrum of GPUs included.

Benchmark Performance

The average benchmark score for this product is 0, which indicates that no meaningful benchmark results are recorded. This is common for older integrated graphics that are not subjected to modern benchmarking suites, but it also means we cannot derive performance deltas against any rivals. The only performance metrics available are the pixel rate and texture rate. The pixel rate of 600.0 MPixel/s and texture rate of 600.0 MTexel/s are derived from the core clock (not specified) and the number of ROPs and TMUs. With 2 ROPs and 2 TMUs, the maximum output is constrained. These rates are extremely low by modern standards; for context, a typical modern GPU achieves rates in the billions of pixels per second, but we cannot state that number because it is not in the pack. The percentile of 50 suggests that in the database's scoring system, it is exactly average, but the average benchmark score of 0 implies that the score is not a meaningful indicator of real-world performance. The lack of benchmark data makes it impossible to compare against specific rivals, but the pixel and texture rates provide a clear picture of its limited throughput. The 110 nm process node and 73 mm² die size also indicate an older manufacturing technology, which likely contributes to lower efficiency compared to newer processes, though no TDP is given.

Who Should Consider It

Given the modest pixel and texture rates, this IGP is only suitable for very basic tasks. It can handle 2D desktop environments, video playback, and simple productivity applications. For 3D gaming, it would be limited to very low resolutions and minimal detail settings, and even then, performance would be poor. The system-shared memory means that the overall system memory configuration will heavily influence performance; faster system RAM can mitigate some bottlenecks, but the GPU's fixed fill-rate limits remain. High-resolution displays are not recommended, as the pixel rate of 600.0 MPixel/s would be insufficient to drive large frame buffers smoothly. Users who need modern features or any form of hardware-accelerated ray tracing should look elsewhere, as this product lacks those capabilities. It is essentially a legacy component for older mobile systems, and its end-of-life status means it is not a viable option for new builds. The PCIe 1.0 x16 interface is an older standard, which may also limit bandwidth in systems with modern CPUs and memory. The display outputs are portable device dependent, meaning they vary by laptop model, so users must check their specific system's capabilities. Overall, this GPU is not intended for any demanding graphics workload; it is a basic integrated solution for basic computing.

Ray Tracing and Feature Set

The Radeon Xpress 1100 Mobile IGP does not include ray tracing cores or tensor cores; these fields are null. The API support is limited to DirectX 9.0 and OpenGL 2.0, with no Vulkan support. DirectX 9.0 is an older API that lacks modern features such as tessellation, compute shaders, and ray tracing. OpenGL 2.0 is similarly outdated, offering only a fraction of the functionality found in contemporary OpenGL versions. The architecture is R300, which is a first-generation shader model architecture, supporting only pixel shader 2.0 and vertex shader 2.0. This means it cannot handle modern shader effects or complex geometry. The bus interface is PCIe 1.0 x16, which provides limited bandwidth compared to modern PCIe generations, though we cannot quantify that without numbers. The display outputs are portable device dependent, meaning they vary by laptop model. There are no power connectors, as it is an IGP that draws power from the motherboard. The process node is 110 nm, which is large by today's standards, leading to higher power consumption relative to newer processes, though no TDP is given. The die size of 73 mm² is relatively small, indicating a low transistor count. Overall, the feature set is minimal, making it unsuitable for any modern graphics workload. The lack of Vulkan support further restricts its compatibility with current games and applications. With no ray tracing or tensor cores, it cannot accelerate any of the latest rendering techniques. This is a product from a bygone era, and its capabilities are strictly limited to basic 2D and early 3D graphics.
