AMD Radeon 625 OEM

Memory Subsystem

The AMD Radeon 625 OEM is equipped with 2 GB of GDDR5 memory, paired with a 64-bit memory bus. This configuration delivers a memory bandwidth of 36.00 GB/s, a figure that is modest by contemporary standards but consistent with its low-power design. The effective memory clock runs at 4.5 Gbps, which is the sole clock specification provided in the datasheet.

For high-resolution workloads, the memory subsystem presents a clear bottleneck. At 1080p, the 2 GB capacity is sufficient for older or lighter titles, but modern games with high-resolution textures will quickly exceed the frame buffer. At 1440p or above, the combination of limited capacity and narrow bus width results in significant performance degradation, as the GPU must constantly swap data between memory and slower system resources. The 36.00 GB/s bandwidth is roughly a third of what mid-range cards from the same era offered, meaning that texture-heavy scenes will exhibit stuttering and reduced frame pacing. The 64-bit bus is the primary constraint here; it halves the potential throughput compared to a 128-bit interface, even with the same memory type and clock. In practical terms, the card is best suited for 720p or low-detail 1080p gaming, where the memory demands are within its reach. For any compute task that requires large datasets in VRAM, the 2 GB limit will force frequent spills to system memory, crippling throughput.

Ray Tracing and Feature Set

The Radeon 625 OEM does not include dedicated ray tracing cores or tensor cores. Its architecture, GCN 3.0, predates the hardware-accelerated ray tracing implementations found in later generations. This means that any ray tracing workload must be handled through compute shaders, which is inefficient and will result in very low frame rates. The card supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170, providing a modern API foundation for feature compatibility. DirectX 12 Ultimate features, such as variable rate shading and mesh shaders, are not supported due to the lack of the required hardware capabilities.

The absence of tensor cores also eliminates any AI-accelerated features like DLSS. While the card can technically run games with ray tracing enabled via software fallbacks, the performance hit is severe enough to render such settings impractical. The feature set is therefore limited to conventional rasterization techniques. For users seeking ray tracing or AI upscaling, this GPU is not a viable option. The Vulkan 1.2.170 support does allow for efficient draw call handling, which can improve CPU-bound scenarios, but this does not compensate for the missing dedicated hardware. In summary, the Radeon 625 OEM is a pure rasterization part, and its feature set reflects its low-end positioning.

Benchmark Performance

The benchmark data for the Radeon 625 OEM is sparse. The average benchmark score is listed as 0, and the percentile versus all GPUs is 50. This percentile is misleading, as it does not indicate a midpoint of performance; rather, it suggests that the card sits at the median of a distribution that includes many integrated and low-end parts. Without any concrete scores in the benchmarks array, we must rely on the architectural specifications to infer performance. The FP32 throughput is 786.4 GFLOPS, which is the same as the FP16 rate (1:1). This is a very low compute figure, roughly a tenth of what a mid-range card from the same period offered.

The pixel rate is 8.192 GPixel/s and the texture rate is 24.58 GTexel/s. These rates are consistent with a GPU designed for minimal power consumption (35 W TDP) rather than raw speed. In synthetic benchmarks, such a card would typically score in the low thousands in 3DMark Fire Strike, but no such numbers are provided. The lack of nearest rivals in the fact pack means we cannot compute exact percentage deltas. However, based on the memory bandwidth and compute rates, the card is expected to perform at a level comparable to entry-level integrated graphics from the same era, though the dedicated GDDR5 memory gives it a slight edge in bandwidth-sensitive tasks. The 8 ROPs are a severe limitation for fill-rate-bound scenarios, such as high-resolution post-processing effects. In practice, expect frame rates below 30 FPS in most modern 3D games at 1080p with low settings. The card is better suited for 2D desktop workloads or legacy titles.

Who Should Consider It

The Radeon 625 OEM is not designed for gaming or content creation. Its specifications point toward office productivity, basic multimedia playback, or as a display adapter for systems where the CPU lacks integrated graphics. With 2 GB of VRAM and 36.00 GB/s bandwidth, it can handle 4K video playback, but not with high dynamic range or high bitrate streams that require advanced decoding. The 384 shading units and 24 TMUs are sufficient for 2D UI rendering and light photo editing, but any 3D application will struggle.

For users with a 720p monitor, the card can run older games (pre-2015) at medium settings, provided they are not VRAM-intensive. At 1080p, the card is limited to esports titles at low settings, where frame rates may reach 60 FPS in less demanding scenes. However, the 35 W TDP and lack of power connectors make it an easy drop-in upgrade for legacy systems with weak power supplies. The PCIe 3.0 x8 interface is adequate for its bandwidth needs. The card is also end-of-life, meaning no driver optimizations are expected going forward. In summary, this is a card for basic compute tasks, not for enthusiasts. If the workload requires 3D acceleration beyond web browsing or office suites, a different GPU is necessary.

How It Compares

The fact pack lists no nearest rivals, and the benchmarks array is empty. Therefore, a direct comparison against specific competing models is impossible. The percentile of 50 indicates that it outperforms half of all GPUs in the database, but this is a statistical quirk given the inclusion of many older and integrated parts. Against integrated graphics from the same period (e.g., Intel UHD 630), the dedicated GDDR5 memory provides a bandwidth advantage, but the compute throughput is similar. Against low-end discrete cards like the GeForce GT 1030, the Radeon 625 OEM would likely trail in raw compute but match in memory bandwidth, depending on the specific SKU. However, without explicit scores, any such comparison is speculative.

The absence of a successor or predecessor in the fact pack (with "Polaris" as predecessor and "Vega" as successor) suggests this is a transitional product. The 28 nm process node and 1,550 million transistors on a 125 mm² die indicate a mature manufacturing technology. The transistor density of 12.4M per mm² is low by modern standards, but it allows for a very cheap and power-efficient chip. The 35 W TDP means no external power is needed, and the single-slot design with no display outputs (as per the fact pack) indicates it is intended for OEM systems where the motherboard provides output connectivity. This is a niche part, and its performance profile should be evaluated solely on the provided metrics, which are uniformly low.
