AMD Radeon R9 M375X

The AMD Radeon R9 M375X is a 28 nm GCN 1.0 GPU built by AMD around the Tropo chip at TSMC. The die contains 1,500 million transistors across 123 mm², giving a transistor density of 12.2M / mm². Its compute configuration is 640 shading units, 40 texture units, and 16 ROPs, with a base clock of 925 MHz and a boost clock of 1015 MHz. Memory is 2 GB of GDDR5 on a 128-bit bus, operating at 1125 MHz / 4.5 Gbps effective and delivering 72.00 GB/s. In the benchmark database it averages 8480, which places it at the 42nd percentile of all GPUs, and its nearest rivals are all within a delta range of -1.4% to 1.9%.

Benchmark Performance

The performance data is built on two Geekbench records: OpenCL at 8288 and Vulkan at 8671. The Vulkan result is the higher of the two, but the difference between the APIs is small relative to the positioning of the card against its nearest rivals. What matters more is how the aggregate average of 8480 sits inside a very tightly packed competitor group.

The AMD FirePro W5170M leads that group with an average score of 8602, putting it 1.4% above the R9 M375X. The Intel Arc A380 follows at 8558, which is 0.9% above. The AMD Radeon HD 8870M is essentially a tie: its average is 8462, and the R9 M375X is 0.2% above it. At the lower end of the cluster, the AMD Radeon RX 550 averages 8324, leaving the R9 M375X 1.9% ahead. These four deltas are all under two percentage points in absolute value, and the entire rival set is compressed between 8324 and 8602.

In practical terms, the data does not support a clear hierarchy. A single driver version or workload type could easily move the R9 M375X past the FirePro W5170M or drop it behind the HD 8870M, because the margins are so thin. The 42nd-percentile rank is a more stable descriptor than any one head-to-head comparison. The card is below the database midpoint, but it is not in the bottom quartile. It trades places with the same class of hardware rather than being clearly faster or slower than its listed rivals.

The raw throughput figures align with that placement. FP32 compute is 1,299.2 GFLOPS, texture fill is 40.60 GTexel/s, and pixel fill is 16.24 GPixel/s. These are mid-range aggregate rates for the era represented by this GPU, and they reinforce the idea that the R9 M375X is a balanced but modest part. The pixel fill rate, in particular, is low enough that fill-heavy scenes will be more constrained than shader-heavy scenes.

Ray Tracing and Feature Set

The specification fields for this GPU contain no RT core count and no tensor core count. Those fields are absent from the data, and no ray tracing workload appears in the benchmark record. The architecture label is GCN 1.0, which is the basis for the feature set. API support is listed as DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. These APIs provide a baseline for modern applications, but the data does not indicate any dedicated hardware ray tracing capability.

The benchmark record includes Vulkan and OpenCL results, so the card has some demonstrated capability under both of those APIs. DirectX 12 (11_1) support is present in the feature list, though there is no corresponding DirectX benchmark in the supplied data. The absence of tensor cores also means that any AI-oriented workload, if considered, would have to rely on general shader hardware rather than dedicated tensor hardware. No such workload is measured in the data, so no performance conclusion can be drawn there. The feature set is, on paper, a conventional GCN 1.0 design with modern low-level API drivers.

The product data also records a release date of 2015-05-04 and a production status of end-of-life. Its predecessor is Solar System and its successor is Polaris Mobile, which places the R9 M375X in a previous-generation transition point rather than a current product stack. The host interface is PCIe 3.0 x16, which is the connection used for system-level data transfers.

Who Should Consider It

The R9 M375X is a below-median performer in the database, with a 42nd-percentile rank. That means most GPUs in the benchmark set score above it. For workloads that fit within its memory configuration, the card can still be usable, but the data points toward lower resolutions and reduced texture settings rather than high-resolution or high-texture workloads. The 2 GB GDDR5 frame buffer and 72.00 GB/s bandwidth are the most restrictive specifications. A 16-ROP configuration at 16.24 GPixel/s further limits pixel throughput, while 40 TMUs keep texture work at 40.60 GTexel/s.

Vulkan 1.2.170 support is worth attention because the card’s highest recorded benchmark score, 8671, comes from a Vulkan workload. OpenGL 4.6 support covers a wide range of older applications. DirectX 12 (11_1) provides a baseline for DX12-era titles, but the 11_1 feature level is not a top-tier DX12 implementation. None of the supplied benchmarks are game traces, so the data cannot confirm how the card behaves in a specific title. The nearest rivals are all close enough that application-specific testing would be required to separate them: the deltas are -1.4%, -0.9%, 0.2%, and 1.9% for the FirePro W5170M, Arc A380, HD 8870M, and RX 550 respectively.

The card is best suited to scenarios where the 2 GB memory capacity is not challenged and where the workload is compute- or shader-bound rather than bandwidth-bound. The FP32 rate of 1,299.2 GFLOPS offers more headroom than the memory subsystem can consistently feed, so memory-heavy settings are more likely to become the limiting factor. Users who only need modest API coverage and a mid-pack synthetic score can consider this GPU, but the data does not suggest it as a high-end choice.

Memory Subsystem

The memory subsystem is the most constrained part of the R9 M375X. It pairs 2 GB of GDDR5 with a 128-bit bus. The memory clock is 1125 MHz, and the effective transfer rate is 4.5 Gbps, producing exactly 72.00 GB/s of bandwidth. That is a modest pipe by the standards of the score range, and it is the specification most likely to limit high-resolution rendering.

The compute side of the GPU is not especially large, but it is still ahead of what the memory interface can comfortably support in bandwidth-sensitive workloads. FP32 throughput is 1,299.2 GFLOPS, while the memory bus provides 72.00 GB/s. In situations where textures must be streamed quickly, the 72.00 GB/s figure will be the ceiling. The 2 GB capacity is a separate ceiling: large texture sets or high-resolution frame buffers can exceed that capacity quickly, forcing data to move across the PCIe 3.0 x16 host interface.

The composition of the render pipeline also matters. The 16 ROPs produce a pixel fill rate of 16.24 GPixel/s, which is a conservative number for a GPU with 640 shading units. The 40 TMUs deliver 40.60 GTexel/s, meaning texture fetching is less constrained than pixel output. That combination suggests a workload that is heavy on texture work but relatively light on final pixel throughput will be more comfortable than one that demands high pixel fill rates. The memory clock of 1125 MHz and 4.5 Gbps effective data rate are the defining inputs for the card’s bandwidth figure, and all other performance characteristics in the data need to be read against that 72.00 GB/s ceiling.
