AMD Radeon R9 M375 vs AMD Radeon RX 7800 XT Comparison

Where Each One Wins

The benchmark data splits these two AMD parts into entirely different performance strata. The AMD Radeon RX 7800 XT dominates every recorded test, while the AMD Radeon R9 M375 trails in both shared workloads. The RX 7800 XT wins both head-to-head benchmarks, leaving the R9 M375 with no victories in any measured category.

For compute-heavy OpenCL workloads, the RX 7800 XT holds a decisive edge. Its Geekbench OpenCL score of 18,290 outpaces the R9 M375's 10,457 by 74.9%. That gap translates into a clear advantage for GPU compute tasks, whether the workload involves rendering, physics simulation, or general-purpose parallel processing. The R9 M375's GCN 1.0 architecture, built on a 28 nm process, simply cannot match the throughput of the newer RDNA 3.0 design.

The Vulkan API test widens the chasm further. The RX 7800 XT posts a Geekbench Vulkan score of 54,228 versus 9,682 for the R9 M375, a 460.1% difference. This is not a marginal improvement; it is a generational leap. Vulkan, being a low-overhead graphics API, rewards modern hardware with higher shader counts and faster memory subsystems. The RX 7800 XT's 3,840 shading units and 624.1 GB/s bandwidth obliterate the R9 M375's 640 shading units and 28.80 GB/s bandwidth in this context.

Beyond the head-to-head results, the database contains additional benchmarks for the RX 7800 XT that the R9 M375 lacks entirely. The RX 7800 XT records a Passmark G3D score of 24,176, a Passmark GPU Compute score of 13,473, and a Passmark G2D score of 1,177. It also logs DirectX 9, 10, 11, and 12 specific scores of 304, 121, 249, and 93 respectively. The R9 M375 has no corresponding entries, meaning the RX 7800 XT wins those categories by default. The 3DMark Steel Nomad DX12 test also appears only for the RX 7800 XT, with a score of 4,157.

The R9 M375 does have one notable characteristic: its percentile ranking. It sits at the 48th percentile among all GPUs in the database, which is remarkably close to the RX 7800 XT's 51st percentile. This proximity is misleading, however, because the R9 M375's average benchmark score of 10,070 is far lower than the RX 7800 XT's 11,627. The percentile figures reflect the distribution of scores across all recorded GPUs, and both cards cluster near the middle, but the absolute performance gap remains enormous.

The Verdict

The data supports a straightforward conclusion: the AMD Radeon RX 7800 XT is the superior product in every measurable way. It wins both head-to-head benchmarks, holds a higher average benchmark score, and supports modern APIs that the R9 M375 cannot fully utilize. Anyone choosing between these two for a new build or upgrade should select the RX 7800 XT without hesitation.

The R9 M375, classified as end-of-life and released in 2015, represents an older generation of AMD mobile graphics. Its GCN 1.0 architecture lacks dedicated ray tracing cores, which the RX 7800 XT provides with 60 RT cores. The R9 M375 also tops out at DirectX 12 (11_1) support, while the RX 7800 XT features DirectX 12 Ultimate (12_2). For modern games and applications that leverage DirectX 12 Ultimate features, the RX 7800 XT is the only viable option.

The RX 7800 XT's nearest rivals in the database include the NVIDIA GeForce GTX 1660 (0.5% lower average score), AMD Radeon Pro 5500M (0.9% lower), NVIDIA Tesla K20c (1.3% lower), and AMD Radeon RX 6500 XT (1.8% higher). This places it in a competitive middle tier where small percentage differences separate cards. The R9 M375, by contrast, sits near the NVIDIA Quadro K5100M (0.3% higher), AMD Radeon Pro 5300M (0.6% lower), NVIDIA GeForce GTX 870M (1.1% lower), and NVIDIA GeForce GTX 950A (2% higher). Neither card leads its immediate peer group, but the RX 7800 XT operates in a far faster performance class.

For users constrained to the R9 M375's capabilities, such as those with an older laptop, the card remains functional for basic graphics tasks. Its 2 GB DDR3 memory and 128-bit bus limit modern gaming, but the recorded Geekbench scores show it can execute OpenCL and Vulkan workloads. The Vulkan score of 9,682 suggests it can handle some light 3D applications. However, no benchmark result indicates that the R9 M375 can compete with the RX 7800 XT on any level.

Head-to-Head Benchmarks

The head-to-head comparison consists of two tests, and the RX 7800 XT wins both by wide margins. The first is Geekbench OpenCL, where the RX 7800 XT scores 18,290 against the R9 M375's 10,457. The 74.9% delta means the RX 7800 XT processes OpenCL workloads nearly 75% faster. This test exercises raw compute throughput, and the RX 7800 XT's 37.32 TFLOPS FP32 performance against the R9 M375's 1,299.2 GFLOPS explains the outcome. The R9 M375 has no FP16 capability listed, while the RX 7800 XT matches FP32 at 37.32 TFLOPS, indicating a balanced compute design.

The second test, Geekbench Vulkan, produces an even more lopsided result. The RX 7800 XT scores 54,228, which is 460.1% higher than the R9 M375's 9,682. This massive delta reflects the architectural gulf between the two GPUs. Vulkan stresses driver efficiency, memory bandwidth, and shader execution. The RX 7800 XT's 16 GB GDDR6 memory on a 256-bit bus delivers 624.1 GB/s, compared to the R9 M375's 2 GB DDR3 on a 128-bit bus at 28.80 GB/s. The memory bandwidth difference alone, roughly 21.7 times greater for the RX 7800 XT, dwarfs the Vulkan score gap, but the score delta still captures the practical impact.

The RX 7800 XT also wins benchmark categories where the R9 M375 has no recorded results. The Passmark G3D score of 24,176 demonstrates strong DirectX 11 performance, while the Passmark GPU Compute score of 13,473 confirms its compute prowess. The 3DMark Steel Nomad DX12 score of 4,157 shows modern API capability. The R9 M375's absence from these tests means the database records zero wins for it across all categories.

Architecture Differences

The two GPUs come from entirely different architectural eras. The RX 7800 XT uses the RDNA 3.0 architecture on a 5 nm TSMC process, featuring the Navi 32 chip under the codename Wheat Nas. The R9 M375 relies on GCN 1.0 architecture on a 28 nm TSMC process, using the Tropo chip from the Gem System generation. The process node difference alone, 5 nm versus 28 nm, explains much of the performance gap, as the smaller node allows for significantly higher transistor density.

Transistor counts reinforce this divide. The RX 7800 XT packs 28,100 million transistors on a 346 mm² die, yielding a density of 81.2M transistors per mm². The R9 M375 contains 1,500 million transistors on a 123 mm² die, with a density of 12.2M per mm². The RX 7800 XT has nearly 19 times more transistors, enabling its massive shader array and memory subsystem.

The memory architectures differ fundamentally. The RX 7800 XT uses 16 GB of GDDR6 memory with a 256-bit bus, operating at 2438 MHz (19.5 Gbps effective) for 624.1 GB/s bandwidth. The R9 M375 uses 2 GB of DDR3 memory on a 128-bit bus, running at 900 MHz (1800 Mbps effective) for 28.80 GB/s. This 21.7 times bandwidth advantage for the RX 7800 XT directly impacts texture streaming, resolution scaling, and compute workloads.

Compute resources also diverge sharply. The RX 7800 XT contains 3,840 shading units, 240 texture mapping units, and 96 raster operation units. The R9 M375 has 640 shading units, 40 TMUs, and 16 ROPs. Pixel and texture rates follow suit: the RX 7800 XT achieves 233.3 GPixel/s and 583.2 GTexel/s, while the R9 M375 manages 16.24 GPixel/s and 40.60 GTexel/s. FP32 performance for the RX 7800 XT is 37.32 TFLOPS, while the R9 M375 delivers 1,299.2 GFLOPS, a difference of more than 28 times.

Clock speeds show the RX 7800 XT running at 1295 MHz base and 2430 MHz boost, with a 2124 MHz game clock. The R9 M375 runs at 1000 MHz base and 1015 MHz boost. The RX 7800 XT's higher clocks, combined with its larger core, produce the observed benchmark dominance. The RX 7800 XT also features PCIe 4.0 x16 connectivity, while the R9 M375 uses PCIe 3.0 x16.

API support separates the cards further. The RX 7800 XT lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The R9 M375 supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The RX 7800 XT also includes 60 RT cores for hardware ray tracing, a feature entirely absent from the R9 M375. Display outputs for the RX 7800 XT include one HDMI 2.1a port and three DisplayPort 2.1 outputs; the R9 M375 has no display outputs listed.
