AMD Radeon 625 Mobile

The AMD Radeon 625 Mobile is an end-of-life mobile graphics processor built on the Polaris 24 chip using a 28 nm process at TSMC. It belongs to the Polaris Mobile (M600) generation and sits at the 50th percentile of all GPUs in the database, placing it exactly at the midpoint of the performance distribution. The chip integrates 1,550 million transistors across a 125 mm² die, with a transistor density of 12.4M per square millimeter. It was released on May 12, 2019, with Gem System as its predecessor and Navi Mobile as its successor.

Memory Subsystem

The Radeon 625 Mobile pairs 2 GB of GDDR5 memory with a 64-bit memory bus. The memory clock runs at 1125 MHz, yielding 4.5 Gbps effective data rate. Total bandwidth is 36.00 GB/s. This is a modest configuration by any measure.

The 64-bit bus is the primary constraint. A narrower bus means fewer memory transactions per clock cycle, and the resulting 36.00 GB/s bandwidth is the ceiling for texture streaming and framebuffer writes. For high-resolution workloads, the 2 GB capacity is the more immediate limitation. Game workloads that require more than 2 GB of VRAM will encounter capacity limits, and when capacity is exhausted, the driver must fall back to system memory over the PCIe 3.0 x8 interface, which is far slower than dedicated VRAM.

The data shows that this memory configuration is suited to 1080p-class workloads with reduced texture quality, rather than high-resolution or high-detail scenarios. At 1440p and above, the combination of limited capacity and narrow bandwidth would create a bottleneck even if the compute resources were sufficient. The 8 ROPs further cap pixel throughput at 8.192 GPixel/s, which directly limits fill-rate-bound operations at higher resolutions. The 24 TMUs and 384 shading units cannot compensate for memory constraints when the frame buffer is saturated.

Who Should Consider It

The Radeon 625 Mobile occupies the 50th percentile of all GPUs in the database. This places it at the median — neither a low-end outlier nor a performance part. However, the raw specifications tell a more specific story. With 384 shading units and 786.4 GFLOPS of FP32 compute, it is a capable entry-level mobile part for light workloads.

The data suggests this GPU is appropriate for users running at 1080p with low to medium detail settings. The 2 GB GDDR5 frame buffer is sufficient for older titles or modern games at reduced texture quality. Users targeting high refresh rates or high-detail 1080p would find the 24.58 GTexel/s texture rate and 8.192 GPixel/s pixel rate limiting.

The 50th percentile ranking indicates that, across the entire database of GPUs, half are slower and half are faster. For a mobile integrated-style part (slot width: IGP, display outputs: Portable Device Dependent), this is a reasonable mid-pack position. It is not designed for enthusiasts or high-end gaming; it is an end-of-life part released in May 2019, and its successor is Navi Mobile. Users who need more performance should look to newer parts.

The FP16 throughput matches FP32 at 786.4 GFLOPS (1:1), which means there is no half-precision advantage for workloads that could benefit from reduced precision. The base clock of 730 MHz and boost clock of 1024 MHz define the operating range, with boost behavior dependent on thermal headroom in the host device.

How It Compares

The nearestRivals data in the database is empty for this GPU, meaning no direct comparable entries were captured in the dataset. The only positional reference is the 50th percentile against all GPUs. This means the Radeon 625 Mobile sits exactly at the median of the entire GPU database: it outperforms half of all recorded GPUs and is outperformed by the other half.

Without named rivals, the comparison must be drawn from the internal specifications. The 786.4 GFLOPS FP32 compute, 24.58 GTexel/s texture rate, and 8.192 GPixel/s pixel rate define its performance envelope. The 2 GB memory capacity and 36.00 GB/s bandwidth are the limiting factors in memory-bound scenarios.

Its predecessor is Gem System and its successor is Navi Mobile, per the database records. The production status is end-of-life, which means it is no longer actively produced. The architecture is GCN 3.0, built on a 28 nm process at TSMC.

FAQ

A: It has 2 GB of GDDR5 memory on a 64-bit bus, with 36.00 GB/s of bandwidth.

Q: What is the TDP of this GPU?

A: The TDP is 50 W. It uses no power connectors and has an IGP slot width, meaning it draws power through the motherboard rather than a dedicated PCIe power cable.

Q: What APIs does it support?

A: It supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170.

Q: Is this GPU still in production?

A: No. The production status is end-of-life. It was released on May 12, 2019.

Q: What is the memory bandwidth?

A: The memory bandwidth is 36.00 GB/s, derived from a 64-bit bus and 1125 MHz memory clock (4.5 Gbps effective).

Q: What is the pixel fill rate?

A: The pixel rate is 8.192 GPixel/s, and the texture rate is 24.58 GTexel/s.

Benchmark Performance

The average benchmark score for the Radeon 625 Mobile in the database is 0, and the benchmarks array is empty. This means no direct benchmark results were recorded. However, the percentile field provides a useful anchor: the GPU sits at the 50th percentile of all GPUs in the database.

Without direct benchmark scores or nearest rivals, the performance analysis must rely on the derived specifications. The FP32 compute is 786.4 GFLOPS, which is the raw arithmetic throughput available for shader work. The texture rate of 24.58 GTexel/s determines how quickly textures can be sampled and filtered. The pixel rate of 8.192 GPixel/s limits how many pixels can be written per second.

These three figures together define the performance envelope. For comparison purposes, a GPU at the 50th percentile is, by definition, in the middle of the pack. The lack of benchmark data means this is a positional ranking rather than a measured score, but it still provides a meaningful reference point.

The 786.4 GFLOPS FP32 figure is the same as the FP16 figure (786.4 GFLOPS with a 1:1 ratio), indicating that the architecture does not offer a half-precision throughput advantage. The base clock of 730 MHz and boost clock of 1024 MHz govern how quickly these figures translate to real-world throughput; the boost clock provides additional headroom for sustained workloads when thermal conditions allow.

Power and Cooling

The Radeon 625 Mobile has a TDP of 50 W. This is the thermal design power, which represents the maximum amount of heat the cooling solution must dissipate under typical sustained workloads. For a mobile part, this is a modest figure that should be manageable with standard laptop cooling.

The slot width is listed as IGP, meaning it is an integrated graphics processor rather than a discrete card. It uses no power connectors, which confirms that it draws power through the motherboard. The display outputs are "Portable Device Dependent," meaning they are determined by the specific laptop or portable device rather than fixed ports on a card.

The database does not include a suggested PSU rating for this GPU. Since it is an IGP part with no power connectors, a dedicated PSU recommendation is not applicable in the same way it would be for a discrete graphics card. The power delivery is handled by the host system's motherboard.

The process node is 28 nm at TSMC, which is a mature process. The die size is 125 mm², and the transistor count is 1,550 million. The transistor density is 12.4M per mm². The 50 W TDP is the only power figure in the database, and it should be considered the reference for thermal design.
