AMD Radeon 880M vs AMD Radeon R9 M375 Comparison

The Verdict

The AMD Radeon 880M is the clear winner in every recorded head-to-head benchmark, and the data does not leave much room for debate. In Geekbench OpenCL, the 880M scores 31,285 against the R9 M375's 10,457, a 66.6% advantage. In Geekbench Vulkan, the 880M posts 40,006 versus 9,682, a 75.8% lead. If you are choosing between these two for any modern workload, the 880M is the only sensible pick.

That said, the R9 M375 is not without a niche. Its average benchmark score of 10,070 places it at the 48th percentile of all GPUs in the database, which is actually higher than the 880M's 43rd percentile. The 880M's average score of 8,436 is dragged down by its Passmark results, which are low (DirectX 9: 97, DirectX 10: 31, DirectX 11: 73, DirectX 12: 32). The R9 M375 has no Passmark entries, so its average reflects only the two Geekbench tests, where it performs respectably for its era. In a legacy system running older APIs, the R9 M375 can still hold its own. For anything modern, the 880M's raw compute and feature set make it the obvious choice.

The 880M is an active product, while the R9 M375 is end-of-life. The 880M is also an IGP with a 15 W TDP, meaning it is designed to sit inside a portable device with no power connectors. The R9 M375 is a discrete mobile GPU from 2015. If you are building or buying today, the 880M is the only one that makes sense. If you are maintaining a legacy laptop and need a drop-in part that works with older software, the R9 M375 remains functional, but the data shows it is massively outclassed.

Where Each One Wins

The Radeon 880M wins every head-to-head benchmark recorded in the database. Its Geekbench OpenCL score of 31,285 is 66.6% higher than the R9 M375's 10,457. Its Geekbench Vulkan score of 40,006 is 75.8% higher than the R9 M375's 9,682. These are not close margins; the 880M is in a different performance class.

The R9 M375's only "win" is in the percentile comparison. It sits at the 48th percentile of all GPUs, versus the 880M's 43rd. That is a function of the benchmark mix, not raw capability. The R9 M375's average score of 10,070 comes from two Geekbench tests, both of which are compute-oriented and do not stress the GPU the way modern DirectX 12 or Vulkan gaming workloads do. The 880M's average of 8,436 includes Passmark results across DirectX 9 through 12, G2D, G3D, and compute, and those scores are low. The Passmark DirectX 11 score of 73 and G3D score of 7,615 suggest the 880M is not a gaming powerhouse in traditional rasterization, despite its impressive compute numbers.

In terms of nearest rivals, the R9 M375 sits within 2% of the NVIDIA Quadro K5100M (10,043, 0.3% delta), the AMD Radeon Pro 5300M (10,013, 0.6% delta), and the NVIDIA GeForce GTX 870M (9,959, 1.1% delta), while trailing the GeForce GTX 950A (10,273) by 2%. The 880M sits within 0.3% of the GeForce GTX 675MX (8,427), ahead of the MX330 (8,458) and Radeon HD 8870M (8,462) by 0.3% each, and ahead of the Radeon R9 M375X (8,325) by 1.3%. So the 880M is competitive with older midrange discrete GPUs, while the R9 M375 is competitive with slightly newer high-end mobile parts from its own generation.

Architecture Differences

The R9 M375 uses the Tropo chip built on GCN 1.0 architecture, fabricated on a 28 nm process by TSMC. It contains 1,500 million transistors on a 123 mm² die, giving a transistor density of 12.2 million per square millimeter. The 880M uses the Strix Point chip on RDNA 3.5 architecture, fabricated on a 4 nm process, also by TSMC. It packs 34,000 million transistors on a 233 mm² die, for a density of 145.9 million per square millimeter. That is a massive architectural jump: from a 2015-era discrete GPU to a 2024-era integrated part.

The R9 M375 has 640 shading units, 40 texture mapping units, and 16 ROPs. It has no ray tracing cores and no tensor cores. The 880M has 768 shading units, 48 TMUs, and 16 ROPs, but it also has 12 ray tracing cores. That is a fundamental feature difference: the 880M supports hardware-accelerated ray tracing, while the R9 M375 does not. The 880M's fp16 throughput matches its fp32 at 4.454 TFLOPS (1:1), while the R9 M375 has no recorded fp16 capability.

The R9 M375 has 2 GB of DDR3 memory on a 128-bit bus, with 28.80 GB/s of bandwidth and a memory clock of 900 MHz (1800 Mbps effective). The 880M uses system shared memory, with bus width and bandwidth listed as system dependent. This is typical of an IGP: it borrows from the host system's RAM, so performance varies with the installed memory.

The R9 M375 supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The 880M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The 880M's DirectX 12 Ultimate support is a major feature advantage, as it includes features like ray tracing and mesh shaders that the R9 M375 cannot access. The 880M also has a PCIe 4.0 x8 interface, while the R9 M375 uses PCIe 3.0 x16.

FAQ

A: The R9 M375 sits at the 48th percentile of all GPUs, while the 880M sits at the 43rd. This is because the R9 M375's average score of 10,070 is based only on two Geekbench tests, while the 880M's average of 8,436 includes Passmark results across multiple DirectX versions and compute workloads, which drag its average down.

Q: How much memory does each GPU have?

A: The R9 M375 has 2 GB of dedicated DDR3 memory on a 128-bit bus. The 880M uses system shared memory, so its capacity and bandwidth depend on the host system.

Q: Which GPU is still in production?

A: The Radeon 880M is active and currently available. The Radeon R9 M375 is end-of-life.

Head-to-Head Benchmarks

The database records two direct head-to-head benchmarks between these GPUs, and the 880M wins both by wide margins.

In Geekbench OpenCL, the 880M scores 31,285 against the R9 M375's 10,457. That is a 66.6% delta in favor of the 880M. OpenCL is a compute-oriented benchmark, and the 880M's 4.454 TFLOPS of fp32 performance, combined with its 768 shading units, gives it a massive compute advantage over the R9 M375's 1,299.2 GFLOPS. The R9 M375's 640 shading units and older GCN architecture simply cannot compete with the newer RDNA 3.5 design.

In Geekbench Vulkan, the gap widens further. The 880M scores 40,006, while the R9 M375 scores 9,682. That is a 75.8% delta. Vulkan is a low-level API that scales well with modern hardware, and the 880M's architecture, which supports Vulkan 1.4, is clearly better optimized for it. The R9 M375 supports Vulkan 1.2.170, but its older GCN 1.0 architecture was not designed with modern low-level APIs in mind.

The 880M also has a significant feature advantage in these tests. Its 12 ray tracing cores and DirectX 12 Ultimate support mean it can handle workloads that the R9 M375 cannot even attempt. While the head-to-head benchmarks do not include a ray tracing test, the architectural data makes it clear that the 880M is the only one of the two capable of such workloads.

Beyond the head-to-head tests, the 880M's Passmark scores show a mixed picture. Its G3D score of 7,615 is respectable, and its compute score of 3,719 is solid. But its DirectX 9 score of 97, DirectX 10 score of 31, DirectX 11 score of 73, and DirectX 12 score of 32 are all low. This suggests that while the 880M is strong in compute and modern APIs, it may not be a gaming-first part. The R9 M375 has no Passmark entries, so its gaming performance is not directly measured in the database, but its Geekbench scores suggest it is a capable midrange part for its time.
