ATI Radeon 3100 IGP

The ATI Radeon 3100 IGP is an integrated graphics processor from AMD, built on the RS780 chip and using the TeraScale architecture. It was released on 2008-03-03 and is now end-of-life. The part is manufactured on a 65 nm process with 180 million transistors on an 85 mm² die, yielding a transistor density of 2.1M per mm². The data set lists no nearest rivals, no benchmark scores, and an average benchmark score of 0, placing it at the 50th percentile of all GPUs in the database.

How It Compares

The nearestRivals field in the FACT PACK is empty, so there are no direct rival comparisons available from the data. The only positional information is the percentileVsAllGpus value of 50, which places this IGP exactly at the median of all GPUs in the database. However, the avgBenchmarkScore is 0, indicating that no actual benchmark runs have been recorded for this part; the percentile therefore reflects a default or neutral placement rather than a measured performance rank. Without rival names, scores, or deltaPct values, the data cannot support statements such as "ahead of X" or "behind Y." The analysis must instead rely on the theoretical specification values: 40 shading units, 4 texture mapping units, 4 raster output units, a pixel rate of 1.400 GPixel/s, a texture rate of 1.400 GTexel/s, and an FP32 throughput of 28.00 GFLOPS. These figures are the only quantitative basis for positioning the part relative to the broader GPU landscape, and they indicate a very low compute and fillrate ceiling. The 50th percentile placement is thus misleading in the absence of measured scores; it does not reflect a competitive midpoint but rather the absence of data. Because no rival entries exist, there are no percentage deltas to report, and the positional analysis ends at the percentile and the theoretical rates.

Who Should Consider It

The Radeon 3100 IGP is an integrated part, with a slot width listed as IGP and display outputs that are motherboard dependent. This means the target user is someone building or maintaining a system around a motherboard that integrates the RS780 chip. The memory subsystem is entirely system shared: size, type, and bus width are all "System Shared," and bandwidth is "System Dependent." Consequently, the graphics performance is tied to the host system's RAM and memory controller. With 40 shading units, 4 TMUs, and 4 ROPs, the part is suited to basic display output and very light graphical workloads. The pixel rate of 1.400 GPixel/s and texture rate of 1.400 GTexel/s cap the fillrate at a low level, so high-resolution rendering is not realistic. The FP32 throughput of 28.00 GFLOPS further limits compute-heavy tasks. Given the release date of 2008-03-03 and the end-of-life production status, this part is relevant only to legacy systems that require an integrated display solution without a discrete card. The DirectX 10.0 (10_0) API support and OpenGL 3.3 support define the software environment, and the absence of Vulkan support means no access to that API. The bus interface is PCIe 1.0 x16, which is the connection to the rest of the system. The transistor count of 180 million and die size of 85 mm² indicate a small, simple chip, consistent with its integrated role. The process node of 65 nm is the manufacturing technology, and the transistor density of 2.1M per mm² follows from the count and die size. For a user with a motherboard built around the RS780 chip, this IGP provides the display output, but the data does not specify any resolution or settings guidance. The system-dependent bandwidth means that the memory performance will vary with the host platform, so a user with faster system memory would see better graphics performance, though no figures are given.

Benchmark Performance

The FACT PACK contains no benchmark entries for this GPU: the "benchmarks" array is empty, and the avgBenchmarkScore is 0. The percentileVsAllGpus of 50 is the only quantitative ranking, but it is not derived from any recorded scores. Therefore, all performance analysis must come from the fixed-function specification rates. The pixel rate of 1.400 GPixel/s means the ROPs can output 1.4 billion pixels per second; the texture rate of 1.400 GTexel/s means the 4 TMUs can sample 1.4 billion texels per second. These two rates are identical, which is consistent with a design where each TMU and ROP operate at the same clock. The FP32 compute of 28.00 GFLOPS is the peak single-precision throughput from the 40 shading units. With no rivals to compare against, the data cannot produce percentage deltas. The 50th percentile placement, taken at face value, would suggest a median position, but the zero average benchmark score contradicts that, indicating that the percentile is a placeholder. In the absence of measured scores, the theoretical rates are the only evidence of performance. A 1.4 GPixel/s pixel rate is low by any standard; the texture rate of 1.4 GTexel/s similarly limits texture-heavy workloads. The FP32 throughput of 28 GFLOPS is the compute ceiling. These numbers, taken together, describe a part that can handle basic 2D output and very light 3D at low resolutions and settings, though the data does not specify resolutions or settings. The 4 ROPs and 4 TMUs are the fixed-function units that drive the pixel and texture rates; with only 4 of each, the parallelism is extremely limited. The 40 shading units are the programmable cores for vertex and pixel shaders, and their FP32 output of 28 GFLOPS is the aggregate compute. Because the memory bandwidth is system dependent, the actual achievable fillrate may be lower than the theoretical peak if the system memory is slow. The data provides no clock speeds for the GPU, so the rates are given as absolute values without a frequency reference.

Memory Subsystem

The memory subsystem of the Radeon 3100 IGP is entirely system shared. The memory size is listed as "System Shared," the memory type is "System Shared," and the bus width is "System Shared." The bandwidth is "System Dependent." This means the GPU does not have dedicated VRAM; it uses a portion of the host system's main memory. The absence of a dedicated memory bus width and bandwidth figure means that the effective memory performance depends entirely on the host platform's memory controller and RAM speed. For high resolutions, this is a significant limitation: the GPU must compete with the CPU for memory bandwidth, and the system-dependent nature of the bandwidth means there is no fixed ceiling. The pixel rate of 1.400 GPixel/s and texture rate of 1.400 GTexel/s are already low, and the shared memory architecture compounds the constraint. In a system with slower RAM, the bandwidth would be lower; in a system with faster RAM, it would be higher, but the data does not quantify any of these scenarios. The lack of a dedicated memory bus also means that the memory clock is not specified — the clock field for memory is "System Shared." For a user considering high-resolution output, the data shows no dedicated memory resources to draw upon; the system shared design ties all graphics memory operations to the host. The bandwidth being "System Dependent" is the only statement about memory throughput, and the bus width being system shared means there is no dedicated interface width. All of this points to a memory subsystem that is fully reliant on the host platform.

Power and Cooling

The FACT PACK lists no TDP for the Radeon 3100 IGP: the tdp field is null. There are also no power connectors (powerConnectors is null) and no suggested PSU (suggestedPsu is null). The slot width is listed as "IGP," which indicates an integrated graphics processor rather than a discrete expansion card. The absence of a TDP value means the data provides no thermal design power figure to guide cooling requirements. Similarly, the lack of a suggested PSU figure means there is no power supply recommendation in the data. The bus interface is PCIe 1.0 x16, which is the connection to the motherboard; for an integrated part, this interface is used for the internal link rather than for a physical card. The display outputs are motherboard dependent, meaning the actual video outputs are determined by the motherboard design, not by the GPU itself. The 65 nm process node and 180 million transistor count on an 85 mm² die suggest a relatively low-power design, but the data does not provide a wattage figure to confirm that. Without a TDP, PSU recommendation, or connector requirements, the power and cooling analysis is limited to the absence of discrete power connectors. The slot width of IGP means no expansion slot is occupied, and no cooler is specified in the data. The transistor density of 2.1M per mm² is a derived figure from the count and die size, and it indicates a relatively simple chip. The production status is end-of-life, which means the part is no longer manufactured, but that does not directly inform power or cooling.

Ray Tracing and Feature Set

The Radeon 3100 IGP has no ray tracing cores: the rtCores field is null. It also has no tensor cores: the tensorCores field is null. The API support is limited to DirectX 10.0 (10_0) and OpenGL 3.3; Vulkan is not supported (vulkan is null). The architecture is TeraScale, and the chip is RS780. The shading units number 40, with 4 TMUs and 4 ROPs. The absence of RT and tensor cores means there is no hardware acceleration for ray tracing or for tensor-based workloads. The DirectX 10.0 support corresponds to the 10_0 feature level, which is the DirectX 10 baseline. OpenGL 3.3 is also a legacy version. The lack of Vulkan support means that any Vulkan-based applications cannot run on this hardware through that API. The feature set is therefore anchored to the mid-2000s era of graphics APIs. The FP32 throughput of 28.00 GFLOPS is the peak compute rate available for all shader workloads, and with no tensor cores, there is no dedicated hardware for matrix operations. The pixel rate of 1.400 GPixel/s and texture rate of 1.400 GTexel/s define the fixed-function throughput. In summary, the feature set is minimal: no RT, no tensor, no Vulkan, and only legacy DirectX and OpenGL support. The TeraScale architecture is the foundational design, and the RS780 chip is the specific implementation. The production status is end-of-life, and the successor is listed as TeraScale 2 IGP, while the predecessor is Radeon IGP. The API list includes only DirectX 10.0 and OpenGL 3.3, with no Vulkan entry.
