AMD Radeon Pro 450 vs AMD Radeon R9 M375 Comparison

# AMD Radeon Pro 450 vs AMD Radeon R9 M375

The AMD Radeon Pro 450 and AMD Radeon R9 M375 are two end-of-life mobile GPUs from different AMD generations, and their benchmark results tell a story of trade-offs rather than a clear knockout. The Pro 450, built on GCN 4.0 with a 14 nm process, edges ahead in average benchmark score at 10804 versus the R9 M375’s 10070, a gap of roughly 7.3%. However, the R9 M375, using older GCN 1.0 on 28 nm, counters with a decisive win in OpenCL performance. The data shows a split decision: the Pro 450 leads in Vulkan and overall average, while the R9 M375 dominates in OpenCL by a significant margin.

Head-to-Head Benchmarks

The direct comparison between these two GPUs is limited to two benchmark tests, and each takes one victory. In Geekbench OpenCL, the AMD Radeon R9 M375 posts a score of 10457, which is 13.9% higher than the Pro 450’s 9002. That is a substantial lead, indicating the R9 M375’s raw compute throughput in OpenCL workloads is notably stronger. The R9 M375’s advantage here aligns with its higher texture rate of 40.60 GTexel/s and pixel rate of 16.24 GPixel/s, compared to the Pro 450’s 32.00 GTexel/s and 12.80 GPixel/s. In raw fill rates, the older card simply has more headroom.

Flip to Geekbench Vulkan, and the tables turn. The AMD Radeon Pro 450 scores 10518, beating the R9 M375’s 9682 by 8.6%. This win is particularly telling because Vulkan is a modern, low-level API, and the Pro 450’s GCN 4.0 architecture with Vulkan 1.3 support (versus the R9 M375’s Vulkan 1.2.170) likely explains the advantage. The Pro 450 also has a higher memory bandwidth at 81.28 GB/s versus the R9 M375’s 28.80 GB/s, which helps in API-heavy workloads that stress memory throughput.

When averaging the two tests, the Pro 450 comes out ahead. Its average benchmark score across all listed tests is 10804, while the R9 M375’s is 10070. That 734-point difference represents roughly a 7.3% overall lead for the Pro 450. Looking at the nearest rivals for context, the Pro 450 sits just 0.4% above the NVIDIA Quadro K2200 (avg score 10761) and 0.7% below the NVIDIA GeForce MX350 (avg score 10883). The R9 M375, meanwhile, is 0.3% above the NVIDIA Quadro K5100M (avg score 10043) but 2% below the NVIDIA GeForce GTX 950A (avg score 10273). In percentile terms, the Pro 450 ranks at the 49th percentile of all GPUs, while the R9 M375 sits at the 48th — a near-tie in overall standing.

The wins are evenly split at one apiece, but the magnitude matters. The R9 M375’s OpenCL victory is larger in percentage terms (13.9%) than the Pro 450’s Vulkan win (8.6%). However, the Pro 450’s higher average score suggests it is more consistent across a broader range of workloads, even if it loses the one specific OpenCL battle.

The Verdict

From the data, the AMD Radeon Pro 450 is the stronger overall choice for most users. Its average benchmark score of 10804 beats the R9 M375’s 10070, and it wins the Vulkan test by 8.6%, which is a modern API that matters for current applications and games. The Pro 450 also has superior memory bandwidth (81.28 GB/s versus 28.80 GB/s) and a more efficient 14 nm process node, which typically translates to better power characteristics — though the R9 M375’s TDP is not listed in the data, so direct power comparison is unavailable.

Choose the AMD Radeon Pro 450 if you prioritize Vulkan performance, modern API support, or a higher average benchmark score. Its 49th percentile ranking versus the R9 M375’s 48th is a small but real edge in overall GPU hierarchy. The Pro 450’s GCN 4.0 architecture and DirectX 12 (12_0) support also suggest better forward compatibility with newer titles that leverage these features.

Pick the AMD Radeon R9 M375 if your workload is heavily OpenCL-based. Its 13.9% lead in that specific test is not trivial, and its higher pixel rate (16.24 GPixel/s) and texture rate (40.60 GTexel/s) mean it can push pixels and texels faster in certain rendering scenarios. That said, the R9 M375’s older GCN 1.0 architecture and lower Vulkan score make it a less versatile option for mixed workloads. The data does not support a general recommendation for the R9 M375 unless OpenCL is your primary use case.

For a balanced user, the Pro 450 is the safer bet. It wins the modern API test, has a higher average score, and offers better memory bandwidth. The R9 M375 is a niche pick for OpenCL-specific tasks where its raw compute advantage shines.

Architecture Differences

The architectural gap between these two GPUs is generational. The AMD Radeon Pro 450 uses the Baffin chip built on GCN 4.0 architecture, manufactured by GlobalFoundries on a 14 nm process. It packs 3,000 million transistors into a 123 mm² die, yielding a transistor density of 24.4 million per mm². The R9 M375, in contrast, uses the Tropo chip based on GCN 1.0, built by TSMC on a 28 nm process. It has only 1,500 million transistors — half the count — but on the same 123 mm² die size, resulting in a much lower density of 12.2 million per mm².

Despite the architectural divide, both GPUs share identical core counts: 640 shading units, 40 texture mapping units, and 16 ROPs. The differences emerge in clock speeds and memory. The R9 M375 runs at a base clock of 1000 MHz with a boost of 1015 MHz, while the Pro 450’s base and boost clocks are not listed in the data. The R9 M375’s higher clocks give it a theoretical FP32 throughput of 1,299.2 GFLOPS, versus the Pro 450’s 1,024.0 GFLOPS — a 26.9% advantage for the older card. The R9 M375 also leads in pixel rate (16.24 GPixel/s) and texture rate (40.60 GTexel/s) over the Pro 450’s 12.80 GPixel/s and 32.00 GTexel/s.

Memory is where the Pro 450 strikes back. Both cards have 2 GB of VRAM on a 128-bit bus, but the Pro 450 uses GDDR5 at 1270 MHz (5.1 Gbps effective), delivering 81.28 GB/s of bandwidth. The R9 M375 uses DDR3 at 900 MHz (1800 Mbps effective), yielding only 28.80 GB/s — less than half the Pro 450’s bandwidth. This memory advantage is likely a key factor in the Pro 450’s Vulkan win, as modern APIs are sensitive to memory throughput.

Feature support also diverges. The Pro 450 supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. The R9 M375 supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The Pro 450 also has FP16 support at 1,024.0 GFLOPS (1:1 ratio), while the R9 M375 lists no FP16 capability. The bus interface differs too: the Pro 450 uses PCIe 3.0 x8, while the R9 M375 uses PCIe 3.0 x16. The Pro 450 is an MXM Module form factor, while the R9 M375’s slot width is not specified.

Where Each One Wins

The AMD Radeon Pro 450 wins in scenarios that favor modern APIs and memory bandwidth. Its Vulkan score of 10518 is 8.6% higher than the R9 M375’s, making it the better choice for Vulkan-based games and applications. The Pro 450’s 81.28 GB/s memory bandwidth is nearly triple the R9 M375’s 28.80 GB/s, which benefits texture-heavy workloads, high-resolution rendering, and any task that saturates memory. Its higher average benchmark score (10804 versus 10070) and 49th percentile ranking (versus 48th) also make it the more consistent performer across a mix of tests. The Pro 450’s support for DirectX 12 (12_0) and Vulkan 1.3 gives it an edge in forward-looking software that leverages these features.

The AMD Radeon R9 M375 wins in raw compute and fill-rate scenarios. Its Geekbench OpenCL score of 10457 beats the Pro 450’s 9002 by 13.9%, making it the superior choice for OpenCL compute workloads like scientific simulations, video encoding, or data processing that rely on this API. The R9 M375’s higher pixel rate (16.24 GPixel/s) and texture rate (40.60 GTexel/s) mean it can fill the screen faster in rasterization-heavy tasks. Its higher FP32 throughput (1,299.2 GFLOPS versus 1,024.0 GFLOPS) also indicates stronger raw shader compute, which can help in certain gaming or rendering workloads that are not memory-bound. The R9 M375’s PCIe 3.0 x16 interface provides double the bandwidth of the Pro 450’s x8 interface for data transfers from the CPU.

In a head-to-head tally, the wins are even at one each, but the Pro 450’s Vulkan victory and higher average score tilt the overall balance in its favor. The R9 M375 is a specialist, not a generalist. If your workload is exclusively OpenCL or relies on raw fill rates, it is the pick. For everything else, the Pro 450’s modern feature set and memory bandwidth make it the more versatile and future-proof option.
