AMD FirePro A300

The AMD FirePro A300 is a mobile integrated graphics processor built on the TeraScale 3 architecture, utilizing the 32 nm Devastator chip fabricated by GlobalFoundries. It was released in the second quarter of 2012 as part of the Trinity Mobile generation, and its production status is end-of-life, positioned between the TeraScale 2 IGP and the GCN 2.0 IGP in the product lineage.

Power and Cooling

The FirePro A300 carries a thermal design power (TDP) of 65 W. This figure represents the total heat envelope for the integrated processor, which includes the CPU cores and the GPU on the same die. The 65 W TDP is a moderate power budget, suggesting that the IGP is suitable for standard mobile chassis designs without exotic cooling solutions.

Since this is an integrated graphics processor (IGP), it occupies a slot width of "IGP" and is mounted directly on the motherboard. Consequently, there are no power connectors required for the graphics portion, and power delivery is handled through the motherboard's standard VRM circuitry. The data does not specify a suggested power supply unit (PSU), which is consistent with its integrated nature — a discrete PSU recommendation is not applicable for a chip that is soldered onto the motherboard.

The absence of a dedicated power connector and the integrated form factor mean that thermal management is entirely dependent on the laptop or all-in-one system's cooling design. The 65 W TDP is a shared budget with the CPU, so the actual thermal headroom for the GPU portion is limited by the system's overall cooling capacity. The chip's process node is 32 nm, and the die size is 246 mm², housing 1,303 million transistors, which results in a transistor density of 5.3M per mm². This density is modest by modern standards, reflecting the aging manufacturing process.

Memory Subsystem

The memory configuration for the FirePro A300 is entirely system-shared. The VRAM size is "System Shared," the memory type is "System Shared," and the bus width is "System Shared." This means the GPU does not have dedicated video memory; instead, it accesses a portion of the system's main RAM through the PCIe 2.0 x16 bus interface.

The memory bandwidth is "System Dependent," which is a critical caveat. The actual performance will vary significantly based on the system's memory configuration — whether it uses dual-channel DDR3 or single-channel, and the speed of that memory. In a best-case scenario with fast dual-channel memory, the available bandwidth can be adequate for low-resolution gaming. However, at high resolutions, the system-dependent nature of the bandwidth becomes a bottleneck.

Because the memory bus width is also system-shared, the GPU is limited by the same memory controller that serves the CPU. This creates contention for bandwidth between CPU and GPU workloads. Benchmark results indicate that this shared arrangement is a significant limiting factor for demanding graphical tasks. The pixel rate is 7.240 GPixel/s, and the texture rate is 21.72 GTexel/s, both of which are constrained by the available memory bandwidth. For high resolutions, the system-dependent bandwidth is unlikely to sustain smooth frame rates, as the memory subsystem cannot deliver data fast enough to feed the 384 shading units efficiently.

Ray Tracing and Feature Set

The FirePro A300 does not include dedicated ray tracing cores or tensor cores. The data lists both `rtCores` and `tensorCores` as null, which confirms that this GPU predates the ray tracing acceleration era. The architecture is TeraScale 3, which does not support hardware-accelerated ray tracing.

In terms of API support, the FirePro A300 supports DirectX 11.2 (specifically the 11_0 feature level) and OpenGL 4.4. There is no Vulkan support listed, which means the GPU cannot leverage modern cross-platform graphics APIs. The lack of Vulkan support is notable for compatibility with contemporary games, as many newer titles require Vulkan or DirectX 12 for optimal performance.

The feature set is therefore limited to legacy DirectX 11 and OpenGL 4.4 workloads. The shading units count is 384, with 24 texture mapping units (TMUs) and 8 render output units (ROPs). The compute capability is rated at 695.0 GFLOPS for FP32, which is a modest figure for general-purpose compute tasks. There is no FP16 data available, indicating that half-precision compute is either not optimized or not supported. The clock speeds are a base of 760 MHz with a boost of 905 MHz. The absence of tensor and RT cores means that any ray tracing or AI-accelerated workloads would have to rely on software implementations, which would be impractically slow given the 695.0 GFLOPS FP32 throughput.

How It Compares

The FACT PACK does not provide `nearestRivals` data for this GPU. Therefore, direct comparisons to specific competitor models cannot be made with quantitative scores or deltas. The `percentileVsAllGpus` field indicates that the FirePro A300 sits at the 50th percentile among all GPUs in the benchmark database. This places it exactly in the middle of the performance distribution.

This median positioning suggests that the FirePro A300 is neither a high-performance part nor a bottom-tier one. Given its integrated nature and the system-shared memory, its real-world performance is heavily dependent on the host system's capabilities. As an end-of-life product from 2012, it would be positioned against other integrated graphics solutions from that era. However, without specific rival data, the comparison must be limited to the percentile ranking.

The absence of benchmark scores (`avgBenchmarkScore` is 0) further complicates direct comparisons. The percentile rank of 50 indicates that in the aggregate database, half of the GPUs perform better and half perform worse. This is a purely relative measure — it does not indicate whether the FirePro A300 is capable of playable frame rates in any specific game or application. The predecessor is TeraScale 2 IGP and the successor is GCN 2.0 IGP, which indicates the architectural progression within AMD's integrated lineup.

Benchmark Performance

The benchmark data for the FirePro A300 is sparse, with no actual benchmark scores recorded in the FACT PACK. The average benchmark score is 0, which means there is no measurable performance data from standardized tests. This absence of data is likely due to the integrated nature of the GPU and the variability of system-dependent memory configurations.

The only quantitative performance indicator available is the percentile rank of 50 against all GPUs. This percentile is derived from the database's aggregate of scores, but since the FirePro A300 has no individual scores, the percentile likely reflects its theoretical positioning based on its specifications. The FP32 compute rating of 695.0 GFLOPS is a raw throughput measure, but it does not translate directly to real-world gaming performance.

Comparing to rivals is impossible without `nearestRivals` data. The FACT PACK explicitly lists an empty array for this field. Therefore, any discussion of percentage deltas against competitors is not possible. The performance analysis must rely on the internal characteristics: the 384 shading units, 8 ROPs, and the system-dependent bandwidth.

The pixel rate of 7.240 GPixel/s and texture rate of 21.72 GTexel/s are fixed hardware limits. At high resolutions, the fill rate may be sufficient for simple scenes, but the system-shared memory bandwidth will throttle performance. The 50th percentile ranking suggests that in the grand scheme of GPU performance, this IGP is an average performer — but this is a broad categorization. In practical terms, the FirePro A300 would be suited for basic desktop productivity, video playback, and older or less demanding games at low settings and resolutions. The lack of Vulkan support and the legacy DirectX 11.2 API limit its compatibility with modern software titles. The 65 W TDP and integrated form factor mean it is not upgradeable or replaceable, cementing its status as a fixed component of the original system.
