AMD Radeon HD 7400G IGP

The AMD Radeon HD 7400G IGP represents a specific moment in integrated graphics history, pairing a TeraScale 3 architecture with the Trinity Mobile generation. Built on a 32 nm process at GlobalFoundries, this IGP packs 1,303 million transistors into a 246 mm² die, yielding a transistor density of 5.3M per mm². Its production status is end-of-life, with an October 2012 release marking its debut, positioned between TeraScale 2 IGP predecessors and GCN 2.0 IGP successors.

Benchmark Performance

The benchmark data for the AMD Radeon HD 7400G IGP is notably sparse — the fact pack lists an average benchmark score of 0, with no individual benchmark entries and no nearest rivals to compare against. This absence of scores is itself revealing: the percentileVsAllGpus sits at exactly 50, placing this IGP precisely in the middle of the GPU performance distribution. However, with no actual benchmark numbers, that midpoint position must be interpreted cautiously.

The theoretical compute figures provide a clearer picture of what this silicon can do. The FP32 throughput stands at 162.8 GFLOPS, derived from 192 shading units operating at a base clock of 327 MHz and a boost clock of 424 MHz. Texture fill rate reaches 5.088 GTexel/s, while pixel rate is 1.696 GPixel/s. These numbers indicate a very modest compute capability, consistent with an integrated part designed for basic display output rather than demanding workloads.

Given the percentile rank of 50, the data suggests this IGP sits exactly at the median of all GPUs ever tracked. Yet with zero benchmark scores recorded, the practical meaning of that percentile is ambiguous — it could reflect a database normalization artifact rather than genuine measured performance. The 12 TMUs and 4 ROPs further reinforce the entry-level positioning, as those counts are far below what discrete graphics solutions of the era offered.

Who Should Consider It

Without benchmark scores or resolution-based performance data, recommendations must derive from the architectural profile. The Radeon HD 7400G IGP is fundamentally a system-shared memory design, meaning its performance scales with whatever RAM is installed in the host laptop. For 720p gaming with low detail settings, the 192 shading units and 4 ROPs suggest playable frame rates only in undemanding titles from the early 2010s.

Users running desktop productivity applications, web browsing, or media playback at 1080p would find this IGP adequate, as those tasks rely more on CPU throughput than GPU rasterization. The 1.696 GPixel/s pixel rate limits fill-rate-heavy scenarios, so high-resolution textures or anti-aliasing would quickly overwhelm the 4 ROPs. For competitive esports titles from 2012-2013, the 424 MHz boost clock provides a ceiling that favors simple geometry and low resolution.

The data implies this IGP targets basic 2D acceleration and video decode rather than 3D gaming. Anyone expecting modern AAA titles at playable frame rates would be disappointed, but that was never the design intent. The system-shared memory bandwidth, listed as "System Dependent," means performance varies wildly based on the host platform’s memory configuration.

Ray Tracing and Feature Set

The Radeon HD 7400G IGP contains no ray tracing cores and no tensor cores — these fields are null in the fact pack. This aligns with its TeraScale 3 architecture, which predates hardware-accelerated ray tracing by years. The DirectX support is 11.2 (11_0), while OpenGL reaches 4.4. Notably, Vulkan support is absent, listed as null.

The API profile reveals a GPU designed for the DirectX 11 era, with no forward-looking hardware features. The 32 nm process and 1,303 million transistors are entirely dedicated to traditional rasterization and compute shaders. The shader model implied by DirectX 11.2 (11_0) supports tessellation and compute shaders, but the modest 162.8 GFLOPS FP32 throughput limits their practical use.

For users interested in modern graphics features, the absence of Vulkan means compatibility with newer titles that rely on that API is impossible. The OpenGL 4.4 support covers many cross-platform games, but performance would bottleneck at the 5.088 GTexel/s texture rate. The display outputs are listed as "Portable Device Dependent," meaning the feature set varies by laptop implementation.

FAQ

Q: What is the maximum DirectX version supported by the Radeon HD 7400G IGP?

A: The IGP supports DirectX 11.2 (11_0), which includes features like tessellation and compute shaders, but no newer API capabilities.

Q: Does this GPU have any ray tracing or tensor core hardware?

A: No, both the ray tracing core count and tensor core count are null, indicating these hardware units are entirely absent from the TeraScale 3 architecture.

Q: How much VRAM does the Radeon HD 7400G IGP have?

A: The memory size is listed as "System Shared," meaning it uses a portion of the host system’s RAM rather than dedicated video memory.

Q: What is the boost clock speed of this IGP?

A: The boost clock is 424 MHz, while the base clock is 327 MHz, giving a modest frequency range for the 192 shading units.

Q: Which Vulkan version is supported?

A: Vulkan support is null, so the IGP does not support the Vulkan API at all.

Q: What is the transistor count and die size?

A: The IGP contains 1,303 million transistors on a 246 mm² die, fabricated on a 32 nm process at GlobalFoundries.

Power and Cooling

The thermal design power (TDP) for the Radeon HD 7400G IGP is rated at 17 W. This is a conservative figure that reflects the integrated nature of the part — it shares the thermal envelope with the CPU it accompanies in the Trinity Mobile platform. No power connectors are listed, which is expected for an IGP that draws power through the motherboard socket rather than a dedicated PCIe power cable.

The suggested PSU field is null, meaning no specific power supply recommendation exists. This is typical for integrated graphics, where the system power budget is determined by the laptop or desktop’s overall design. The slot width is listed simply as "IGP," confirming that no expansion slot is required — the GPU is soldered onto the motherboard or embedded in the CPU package.

Cooling requirements are inherently modest given the 17 W TDP. A basic heat pipe or even passive cooling in some chassis designs would suffice, as the 32 nm process keeps power density reasonable. The 246 mm² die size with 1,303 million transistors produces 5.3M transistors per mm², a figure that indicates a relatively relaxed thermal density compared to later, more compact designs.

Memory Subsystem

The memory configuration is entirely system-shared, with the size, type, and bus width all listed as "System Shared." This means the IGP has no dedicated VRAM and instead borrows from the host system’s main memory. The bandwidth is described as "System Dependent," acknowledging that performance scales directly with the installed RAM’s speed and channel configuration.

This architecture has significant implications for high-resolution workloads. Since the GPU and CPU compete for the same memory bandwidth, 1080p gaming or any memory-intensive task would suffer from contention. The 4 ROPs further constrain fill rate, so 1440p or 4K resolutions would be entirely impractical. The system-shared design also means that faster dual-channel DDR3 memory could improve performance, but the IGP’s modest compute power (162.8 GFLOPS) would still bottleneck before memory bandwidth becomes the limiting factor.

For basic desktop use at 1080p, the system-shared memory is sufficient, as 2D composition and video decode require far less bandwidth than 3D rendering. However, the lack of dedicated VRAM means texture loading and frame buffering rely on system memory latency, which is higher than dedicated GDDR solutions. The "System Dependent" bandwidth figure underscores that this IGP’s memory performance is entirely a function of the host platform.

How It Compares

The fact pack lists no nearest rivals for the Radeon HD 7400G IGP, which makes direct comparisons impossible based on available data. This absence is notable — most GPUs have at least one competitor in their performance class, but this IGP’s benchmark score of 0 and empty rival list suggest it either wasn’t benchmarked against peers or was considered too low-end to warrant comparison.

Its positional relationship can be inferred from the generation lineage: it succeeds TeraScale 2 IGP and precedes GCN 2.0 IGP. This places it within the AMD integrated graphics roadmap, where each generation typically brought modest IPC and feature improvements. The percentile rank of 50 indicates a median position among all GPUs, but without rival scores, that percentile cannot be validated against specific competitors.

The absence of rival data also means no delta percentages exist to quantify performance gaps. In relative terms, the 192 shading units and 12 TMUs define a clear performance tier, but whether that tier sits above or below specific Intel HD Graphics or NVIDIA IGP solutions from 2012 cannot be stated from the fact pack alone. The data simply does not support any comparative claims beyond the broad generation context.
