ATI Radeon Xpress 1250 IGP

The ATI Radeon Xpress 1250 IGP is an integrated graphics processor from AMD, built around the RS690 chip and R400 architecture. Fabricated on an 80 nm process, the die contains 120 million transistors across 73 mm², yielding a transistor density of 1.6M per mm². Released on 2007-02-27, this part is now end-of-life, with the TeraScale IGP listed as its successor. It carries 4 texture mapping units and 4 render output units, with a pixel rate of 1.600 GPixel/s and a texture rate of 1.600 GTexel/s. The part connects via PCIe 1.0 x16, and its display outputs are motherboard dependent.

Memory Subsystem

The memory subsystem is entirely system shared. Size, type, and bus width are all listed as "System Shared," meaning the IGP has no dedicated VRAM of its own. Bandwidth is "System Dependent" — it relies entirely on the host system's RAM and memory controller. This has direct implications for high resolutions: the IGP must compete with the CPU for memory bandwidth, and the available bandwidth scales with the platform's memory configuration. With a pixel rate of 1.600 GPixel/s and texture rate of 1.600 GTexel/s, the part's fillrate capabilities are fixed regardless of memory, but the effective throughput in real workloads will be limited by how much bandwidth the system can spare. For high resolutions, the shared nature means performance will degrade as resolution increases, because larger framebuffers consume more of the shared pool. The lack of dedicated VRAM also means that texture-heavy scenes will be constrained by system memory latency and bandwidth. The 4 TMUs and 4 ROPs are modest, and they will be the bottleneck in many scenarios, but the memory subsystem's dependence on the host platform is the more fundamental constraint. There is no fixed bus width to quote, because the bus width is whatever the system's memory bus provides. Similarly, there is no fixed memory clock. The practical takeaway is that this IGP's memory performance is only as good as the system it is installed into, and that system dependency is the defining characteristic of its memory subsystem. The "System Dependent" bandwidth label means that two systems with different RAM configurations will produce different memory performance from the same IGP, so no single bandwidth figure can be attached to the part itself.

Who Should Consider It

The data shows an average benchmark score of 0, with no individual benchmark entries recorded in the database. The part sits at the 50th percentile of all GPUs in the database. This percentile position indicates a midpoint ranking, but with no actual benchmark scores to back it up, the practical guidance must be qualitative. The part supports DirectX 9.0b (9_2) and OpenGL 2.0, which limits it to games and applications from that era. For modern high-resolution gaming, this IGP is not suited; the shared memory subsystem and modest fillrate (1.600 GPixel/s pixel rate, 1.600 GTexel/s texture rate) will struggle. For older titles designed around DirectX 9.0b, at low resolutions and reduced settings, the part may be usable, but the absence of benchmark data means no specific frame rate expectations can be stated. The 50th percentile ranking suggests it is neither a standout nor a bottom-dweller in the database, but that ranking is based on the database's percentile field, not on measured scores. Consider this part only for basic 2D desktop work, legacy applications, or as a fallback display output, given that display outputs are motherboard dependent and the bus interface is PCIe 1.0 x16. For any demanding 3D workload, the data does not support a recommendation. The 4 TMUs and 4 ROPs are the only fixed execution resources, and they are low by any standard. Resolution should be kept low, and settings should be minimal. There is no evidence in the data for high-resolution or high-settings gaming. The end-of-life production status further narrows its relevance to existing systems rather than new builds.

Benchmark Performance

The FACT PACK contains no benchmark scores for this part. The benchmarks array is empty, and the average benchmark score is 0. Consequently, there are no exact percentage deltas to report against any rival, because no rivals are listed in the nearestRivals field. The only quantitative performance indicators available are the fixed hardware rates: pixel rate of 1.600 GPixel/s and texture rate of 1.600 GTexel/s. These rates describe the maximum fillrate the hardware can produce, but they are not application-level benchmark scores. In the absence of measured data, the percentileVsAllGpus field of 50 provides a relative position: this IGP sits at the midpoint of all GPUs in the database. That percentile is a database-level ranking, not a score, and it should not be interpreted as a performance measurement. The lack of benchmark entries means that any statement about frame rates, relative speed, or percentage differences would be unsupported. The data simply does not contain the information needed for a comparative benchmark analysis. What can be stated is that the part's fixed resources — 4 TMUs, 4 ROPs, 1.600 GPixel/s, and 1.600 GTexel/s — are the only hardware facts available, and they indicate a very low-end part by modern standards. Without rival scores, no deltaPct values can be computed. The average benchmark score of 0 reinforces that no measurements have been recorded. In short, the benchmark performance section must rely on the absence of data: there are no scores to analyze, no rivals to compare, and no percentage differences to report. The pixel and texture rates are the only numeric performance indicators, and they describe theoretical maxima rather than real-world results.

How It Compares

The nearestRivals field is empty, so there are no rival GPUs listed in the database for this part. No names, no scores, and no deltaPct values are provided. Therefore, no direct comparison to any specific rival can be made. The only relational data point is the percentileVsAllGpus value of 50, which places this IGP at the midpoint of the entire GPU database. That is a broad, database-wide position rather than a head-to-head comparison. The successor field lists TeraScale IGP, indicating the next generation in the product line, but no performance relationship is given. The predecessor field is null, so no prior part is identified. In the absence of nearest rivals, the comparison section cannot offer the usual percentage-based statements. What can be said is that the part occupies the 50th percentile of all GPUs in the database, meaning half of the listed GPUs rank above it and half below — though this is a percentile field, not a measured benchmark. The production status is end-of-life, so it is no longer a current product. The bus interface is PCIe 1.0 x16, which is an older generation. The display outputs are motherboard dependent, meaning the comparison set is further constrained by the motherboard it is integrated into. Without rival data, the comparison is limited to these positional facts. The 80 nm process and 73 mm² die size place it in a specific manufacturing era, but those are physical attributes, not comparative performance metrics.

Power and Cooling

The FACT PACK lists no TDP value for this part. The suggested PSU field is null, and no power connector requirements are provided. The slot width is listed as "IGP," which indicates an integrated graphics processor rather than a discrete add-in card. Because it is an IGP, it does not occupy an expansion slot in the conventional sense, and its power delivery is handled by the motherboard. However, the data does not specify any wattage figure, so no power draw estimate can be stated. The absence of a suggested PSU value means the database provides no guidance on power supply sizing. Similarly, the powerConnectors field is null, so no connector types can be reported. The display outputs are motherboard dependent, which further ties the power and cooling behavior to the specific motherboard implementation. The process node is 80 nm, and the die size is 73 mm² with 120 million transistors; these physical facts give a general sense of the part's scale, but they do not translate into a TDP number without additional data. The transistor density of 1.6M per mm² is a physical property, not a power property. For cooling, the data does not specify any cooler requirements. As an IGP, the cooling solution is typically integrated into the motherboard or the system's overall thermal design, but the FACT PACK does not confirm this. In summary, the power and cooling section has no numeric TDP, no PSU recommendation, and no connector information to report. The only relevant facts are the slot width of "IGP" and the motherboard-dependent display outputs, which imply that power and cooling are handled at the motherboard level rather than by a discrete card. Without a TDP figure, no thermal design power can be quoted, and without a suggested PSU, no power supply guidance can be given. The 80 nm process and 73 mm² die size are the only physical characteristics available, and they are not power ratings. Builders should treat this part as a motherboard-integrated solution whose power and thermal behavior is determined by the host platform, not by any specification on the GPU itself.
