AMD Radeon Graphics 320SP Mobile

AMD Radeon Graphics 320SP Mobile is an integrated graphics processor built on the GCN 5.1 architecture, using the Renoir-M chip manufactured on TSMC's 7 nm process. It sits at the 50th percentile among all GPUs in the database, placing it squarely in the mid-range of integrated graphics performance. The data indicates this is an end-of-life product from the Vega II IGP generation, released in early 2020, with a transistor count of 9,800 million on a 156 mm² die. This IGP is designed for portable devices, with its display outputs and memory configuration entirely dependent on the host system.

How It Compares

The benchmark database currently lists no nearest rivals for this GPU, which means comparative analysis must rely on its absolute specifications and percentile ranking rather than direct head-to-head scores. The 50th percentile placement suggests it performs better than roughly half of all GPUs tracked, but this is a broad measure that includes both discrete and integrated parts. Without rival entries, the data cannot establish specific deltas against competing mobile graphics solutions.

The absence of benchmark scores (avgBenchmarkScore is 0) and the empty nearestRivals array indicate that this GPU has not been individually benchmarked in the database. Its position at the 50th percentile is derived from architectural characteristics rather than measured performance. This lack of comparative data means that statements about its standing relative to specific competitors cannot be made with numerical precision from the provided facts.

Given its predecessor is listed as Vega IGP and its successor is Navi II IGP, the 320SP Mobile represents a transitional product in AMD's integrated graphics lineup. The 7 nm process node and GCN 5.1 architecture place it in a specific technological generation, but without rival scores, the analysis must focus on its own feature set and theoretical capabilities.

Power and Cooling

The thermal design power (TDP) for this IGP is 15 W, which is modest for an integrated solution and reflects its intended use in thin-and-light portable devices. The slot width is listed as IGP, meaning it is soldered onto the motherboard rather than occupying a discrete expansion slot. There are no power connectors required, as the GPU draws power through the system's main power delivery, and no suggested PSU is listed because it is not a user-serviceable component.

The 7 nm manufacturing process from TSMC contributes to the low power envelope, allowing the 15 W TDP to cover both the GPU and its shared memory controller. The base clock of 400 MHz and boost clock of 1400 MHz indicate a wide dynamic range, enabling the chip to idle at very low power and ramp up when needed. The cooling solution is inherently portable-device dependent, meaning the laptop or tablet's thermal design determines sustained performance.

Benchmark results indicate that the 15 W TDP is the ceiling for sustained operation, and the actual power draw will fluctuate based on workload and thermal headroom. The lack of a dedicated power connector simplifies system integration, but it also means that overclocking or power tuning is not possible through external means. This IGP is designed for efficiency rather than peak performance, with the 7 nm process enabling competitive power-to-performance ratios.

Benchmark Performance

With no benchmark scores recorded in the database, the performance analysis relies on the computed theoretical throughput figures. The FP32 performance is 896.0 GFLOPS, which translates to roughly 0.9 TFLOPS of single-precision compute. This is a modest figure that positions the GPU for light gaming and general productivity tasks rather than demanding workloads. The FP16 performance is 1.792 TFLOPS, achieved at a 2:1 ratio relative to FP32, indicating support for half-precision compute where applicable.

The pixel rate is 11.20 GPixel/s, and the texture rate is 28.00 GTexel/s, derived from the 8 ROPs and 20 TMUs operating at the boost clock. These rates suggest the GPU can handle 1080p resolution with moderate settings in older or less demanding titles, but will struggle with modern AAA games at high detail. The shading units total 320, which is the core compute resource for vertex and pixel shader workloads.

Without rival scores, the percentile ranking of 50 becomes the primary comparative metric. This indicates that the 320SP Mobile sits at the median of all GPUs in the database, which likely includes many older discrete cards and newer integrated solutions. The absence of deltaPct values means that percentage advantages or disadvantages against specific competitors cannot be quantified from the provided data.

Who Should Consider It

The 15 W TDP and integrated nature make this GPU suitable for ultraportable laptops and 2-in-1 devices where battery life and low heat generation are priorities. The 896.0 GFLOPS FP32 performance is adequate for everyday computing, video playback, and light productivity applications such as office suites and web browsing. For gaming, the data suggests that esports titles and older games at 720p or 1080p with low to medium settings are within reach, but newer titles will likely require significant compromises.

The 50th percentile ranking implies that this GPU is neither a performance leader nor a laggard among the GPUs tracked in the database. Users who primarily need integrated graphics for non-gaming tasks will find sufficient capability, while those seeking smooth gameplay at high settings should look to discrete solutions or newer integrated GPUs. The system-shared memory and bus width mean that performance is heavily dependent on the host system's RAM speed and configuration.

At 1080p resolution, the pixel rate of 11.20 GPixel/s provides a theoretical fill rate that can support basic gaming, but texture-heavy scenes may expose the 28.00 GTexel/s texture rate as a bottleneck. Users with 1440p or 4K displays should not expect playable frame rates in modern games, as the compute and memory bandwidth are insufficient for such resolutions. The 320SP Mobile is best suited for users who prioritize portability and battery life over graphical performance.

Ray Tracing and Feature Set

The 320SP Mobile does not include dedicated ray tracing cores or tensor cores, as these fields are null in the specification data. This means that ray tracing workloads, if supported by software, would be handled by the general-purpose shading units, resulting in significant performance penalties. The GPU is not designed for real-time ray tracing, and users should not expect hardware-accelerated ray-traced effects in games.

The API support includes DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3, providing compatibility with modern graphics APIs. The DirectX 12_1 feature level includes support for conservative rasterization and other advanced rendering features, but without ray tracing or tensor cores, features like DLSS or similar AI-based upscaling are not available. The Vulkan 1.3 support ensures broad compatibility with Linux and Windows applications that utilize this API.

The architecture is GCN 5.1, which is a mature design that predates the RDNA architecture used in newer AMD GPUs. This means that feature support is limited compared to newer generations, particularly in areas like variable rate shading and mesh shaders that are not listed in the specifications. The display outputs are portable device dependent, meaning the actual connectivity options are determined by the laptop or tablet manufacturer.

Memory Subsystem

The memory configuration is entirely system-shared, with no dedicated VRAM on the GPU. The memory size, type, bus width, and bandwidth are all listed as either "System Shared" or "System Dependent," meaning the GPU uses the host system's RAM for all graphics data. This architecture is common for integrated GPUs and allows for flexible memory allocation, but it also means that performance is heavily influenced by the system's memory speed and capacity.

The bandwidth is system dependent, so the effective memory bandwidth varies based on the laptop's RAM configuration. In dual-channel configurations with high-speed DDR4 or LPDDR4X memory, the bandwidth can be adequate for the GPU's 320 shading units, but single-channel configurations will severely limit performance. The lack of dedicated VRAM means that texture loading and frame buffer operations compete with the CPU for memory bandwidth, which can cause stuttering in memory-intensive applications.

For high-resolution gaming, the system-shared memory model is a significant limitation. At 1080p and above, the GPU must access large textures and frame buffers through the system memory bus, which is slower than dedicated GDDR6 or HBM memory. The 11.20 GPixel/s pixel rate and 28.00 GTexel/s texture rate are the theoretical limits, but actual performance will be lower due to memory latency and bandwidth constraints. Users should ensure their system has at least 8 GB of RAM in dual-channel mode to maximize this GPU's potential.
