ATI Radeon 3100 Mobile IGP

The ATI Radeon 3100 Mobile IGP is an AMD integrated graphics processor built on the RS780 chip, using TeraScale architecture. The fact pack identifies it as part of the TeraScale IGP (Mobility HD 3000) generation and lists a 65 nm process, 180 million transistors, an 85 mm² die size, and a transistor density of 2.1M / mm². It has 40 shading units, 4 texture mapping units, and 4 ROPs. The product was released on 2008-08-14 and is marked End-of-life. Its predecessor is Radeon IGP and its successor is TeraScale 2 IGP.

Benchmark Performance

Benchmark performance cannot be quantified from this fact pack. The benchmarks array is empty, the average benchmark score is 0, and nearestRivals is empty. There are therefore no exact percentage deltas to report against any rival. The database does place the part at the 50th percentile versus all GPUs, but because the average benchmark score is 0, that percentile is not supported by a positive benchmark sample.

What the pack does provide are hardware throughput ceilings. FP32 arithmetic is 28.00 GFLOPS, pixel rate is 1.400 GPixel/s, and texture rate is 1.400 GTexel/s. These are peak specification limits rather than tested application scores. The pixel and texture rates are equal at 1.400, indicating that the 4 TMUs and 4 ROPs operate at the same rate in the data's terms. No clocks are listed for the GPU, and the memory clock is "System Shared", so there is no fixed clock-based performance estimate. The 40 shading units, 4 TMUs, and 4 ROPs define the execution resources, but without workloads or clocks, a score cannot be derived. The database shows no benchmark evidence for this IGP, and the only numeric anchors are the throughput fields.

How It Compares

The nearestRivals field in the fact pack is empty. No rival names, no rival scores, and no deltaPct values are available for comparison. Consequently, the ATI Radeon 3100 Mobile IGP cannot be positioned against specific competing GPUs in this database.

The only relational entries are predecessor and successor: Radeon IGP before it and TeraScale 2 IGP after it. Those are generational descriptors, not benchmark comparisons. The database percentile versus all GPUs is 50, which is a positional rank rather than a head-to-head measurement. Without nearestRivals entries, a paragraph-by-paragraph comparison to each rival is impossible; there are zero rival records in the data. The absence of comparison points is itself a finding: the data set does not support statements such as "ahead of X" or "behind Y".

Power and Cooling

The power and cooling data in the fact pack is sparse. TDP is null, meaning no thermal design power figure is recorded. Suggested PSU is also null, so no power supply recommendation is attached to this part. The slot width is "IGP", indicating an integrated graphics placement rather than a discrete expansion card. Power connectors are listed as "None", so the data does not indicate any auxiliary power cable requirement. Display outputs are "Portable Device Dependent", which ties the physical output implementation to the host portable device rather than to a fixed set of connectors. No dimensions are listed: length, height, and width are all null.

Because no TDP or PSU figures exist, the thermal and electrical requirements are not specified in the data. The absence of power connectors means no auxiliary connector is listed; the slot width "IGP" indicates the part is integrated rather than a discrete card. The fact pack does not state a wattage figure, so cooling needs must be considered only through the host system context that the data leaves unquantified.

FAQ

Q: Are there any benchmark scores?

A: The benchmarks array is empty. Average benchmark score is 0, while the percentile versus all GPUs is 50.

Who Should Consider It

Given the fact pack, only a limited recommendation is possible. The product is an IGP, not a discrete card, and its display outputs are portable-device dependent. That points toward mobile systems that need graphics integrated into the platform. However, no benchmark scores are recorded, so a resolution/settings recommendation cannot be grounded in measured performance. The 50th percentile placement suggests a median database position, but the 0 average benchmark score undermines using that rank as evidence.

The memory subsystem is entirely system-shared, meaning any resolution scaling would depend on the host system's memory bandwidth; the fact pack labels that bandwidth as "System Dependent". The APIs limit the software context: DirectX 10.0 (10_0) and OpenGL 3.3, with no Vulkan. Thus, users should consider it only for software and workloads that target those API levels and an integrated form factor. Because it is End-of-life, the data does not present it as a current platform component. The database can support a description of what the part is, but not a performance-based recommendation for a specific resolution and settings level.

Memory Subsystem

The memory subsystem is entirely shared. Memory size is "System Shared", memory type is "System Shared", bus width is "System Shared", and memory clock is "System Shared". Bandwidth is "System Dependent". This means there is no dedicated VRAM pool, no fixed memory bus width, and no board-specific memory clock for this IGP.

From a high-resolution standpoint, the absence of fixed bandwidth makes performance predictions impossible from the fact pack. The bus interface is PCIe 1.0 x16, which is the listed connection to the host. The IGP must rely on the host system's memory, so any high-resolution workload would compete for the same system memory resources; however, the pack does not quantify that competition.

The only fixed numbers in the memory section are the rates: pixel rate 1.400 GPixel/s and texture rate 1.400 GTexel/s. These are not memory bandwidth figures; they are rasterization and texture throughput ceilings. Without a dedicated memory bus, the data's memory section contains no width or speed values to compare.

Ray Tracing and Feature Set

The fact pack lists no ray tracing cores and no tensor cores; both fields are null. The feature set therefore does not include hardware ray tracing or tensor core processing as represented in the database. The API support consists of DirectX 10.0 (10_0) and OpenGL 3.3. Vulkan is null, so no Vulkan entry exists in the data.

The architecture is TeraScale, and the generation is TeraScale IGP (Mobility HD 3000). The pixel rate is 1.400 GPixel/s and the texture rate is 1.400 GTexel/s, which bound the rasterization and texturing work this part can perform. FP32 throughput is 28.00 GFLOPS, available as the general compute ceiling.

Without rtCores or tensorCores, there is no dedicated acceleration for those workloads in the data. The absence of Vulkan further constrains the API surface. The feature set is defined by 40 shading units, 4 TMUs, 4 ROPs, and the listed DirectX and OpenGL versions.
