AMD Radeon R9 M375 vs NVIDIA TITAN V CEO Edition Comparison

The Verdict

The AMD Radeon R9 M375 and NVIDIA TITAN V CEO Edition occupy completely different corners of the GPU market, and the data reflects that separation clearly. The R9 M375 is an older, small mobile part built on GCN 1.0, aimed at thin-and-light laptops that need basic 3D acceleration. The TITAN V CEO Edition is a desktop behemoth with a Volta architecture, 32 GB of HBM2, and tensor cores, designed for compute-heavy workloads.

Looking strictly at the average benchmark scores, the R9 M375 actually records a higher average (10070) than the TITAN V CEO Edition (9037). That is a surprise at first glance, but the TITAN V's average is dragged down by its PassMark G2D score of 1086, while its G3D score of 16988 is in another universe. The R9 M375's two Geekbench scores (OpenCL 10457, Vulkan 9682) are both in the same ballpark, while the TITAN V is a Jekyll-and-Hyde split between 2D and 3D performance.

For a buyer, the verdict is simple. If you need a GPU for basic mobile graphics, light gaming, or legacy DirectX 11 workloads, the R9 M375 is the only one of the two that fits in a laptop chassis. If you need serious compute power, massive memory bandwidth, or tensor core acceleration, the TITAN V CEO Edition is the only choice that even approaches that tier. There is no scenario where these two compete for the same purchase decision.

Architecture Differences

The R9 M375 is built on AMD's GCN 1.0 architecture, using the Tropo chip fabricated on a 28 nm process at TSMC. It packs 1,500 million transistors into a 123 mm² die, giving a transistor density of 12.2 million per square millimeter. The TITAN V CEO Edition uses NVIDIA's Volta architecture, with the GV100 chip on a 12 nm process, also at TSMC. It contains 21,100 million transistors on an 815 mm² die, for a transistor density of 25.9 million per square millimeter. That is roughly 14 times more transistors on a die 6.6 times larger.

The R9 M375 has 640 shading units, 40 texture mapping units, and 16 ROPs. It has no tensor cores and no RT cores. The TITAN V has 5120 shading units, 320 TMUs, and 128 ROPs, plus 640 tensor cores. The FP32 compute output tells the story: 1,299.2 GFLOPS for the R9 M375 versus 14.90 TFLOPS for the TITAN V, an 11.5 times difference. The TITAN V also offers FP16 at 29.80 TFLOPS with a 2:1 ratio, while the R9 M375 has no listed FP16 capability.

Memory architecture is radically different. The R9 M375 uses 2 GB of DDR3 on a 128-bit bus, delivering 28.80 GB/s of bandwidth. The TITAN V has 32 GB of HBM2 on a 4096-bit bus, delivering 868.4 GB/s. That is 30 times more memory capacity and 30 times more bandwidth. The bus width difference alone, 4096 bits versus 128 bits, is a 32-fold gap.

Where Each One Wins

The R9 M375 wins in average benchmark score, with 10070 versus 9037 for the TITAN V. This is because the R9 M375's two GeekBench scores are both above the 10000 mark, while the TITAN V's PassMark G2D result of 1086 pulls its average down hard. If you were to look only at the average, you might mistakenly think the mobile part is faster.

The R9 M375 also wins in the GeekBench OpenCL and Vulkan tests, though the TITAN V was not run on those tests. The recorded data shows the R9 M375 scoring 10457 in OpenCL and 9682 in Vulkan, both respectable for a mobile part from 2015.

The TITAN V CEO Edition wins overwhelmingly in pure 3D rasterization. Its PassMark G3D score is 16988, which is in a completely different class. The G2D score of 1086 is low, but that test measures 2D graphics acceleration, not gaming or compute. The TITAN V also wins on every architectural metric: raw shader count, texture fill rate, pixel rate, memory bandwidth, and FP32 output.

For actual gaming or GPU-accelerated compute, the TITAN V is the clear winner. For integrated-style mobile graphics with low power draw and minimal footprint, the R9 M375 has its place.

Head-to-Head Benchmarks

There are no direct head-to-head benchmark tests recorded between these two GPUs, so the comparison must rely on their individual benchmark suites and the relative position to their nearest rivals.

The R9 M375 shows strong GeekBench results. Its OpenCL score of 10457 places it 0.3 percent above the NVIDIA Quadro K5100M (10043) and 0.6 percent above the AMD Radeon Pro 5300M (10013). Its Vulkan score of 9682 is also solid, though no direct rival data exists for that test. The R9 M375's average score of 10070 places it in the 48th percentile of all GPUs in the database.

The TITAN V CEO Edition has a PassMark G3D score of 16988, which is its strongest metric. Its G2D score is only 1086, which is expected for a compute-focused card that is not optimized for 2D desktop tasks. The average score of 9037 puts it in the 45th percentile, which is lower than the R9 M375's percentile ranking. However, this is misleading because the TITAN V's G3D score alone would place it far above the R9 M375.

The nearest rival data for the TITAN V shows it sitting between the NVIDIA GeForce GTX 560 (9058, 0.2 percent higher) and the NVIDIA GeForce GTX 660 (9022, 0.2 percent lower). The AMD Radeon 550X is 1.3 percent lower, and the AMD Radeon 890M is 1.9 percent higher. These rivals are all older or lower-tier parts, which shows that the average score does not capture the TITAN V's true 3D capability.

For the biggest wins, the TITAN V wins on raw compute by a massive margin. Its FP32 throughput is 14.90 TFLOPS versus 1,299.2 GFLOPS, a 11.1 times advantage. Its texture rate is 465.6 GTexel/s versus 40.60 GTexel/s, an 11.5 times advantage. Its pixel rate is 186.2 GPixel/s versus 16.24 GPixel/s, an 11.5 times advantage. Memory bandwidth is 868.4 GB/s versus 28.80 GB/s, a 30.1 times advantage.

The R9 M375's wins are narrower. Its average score is 10.2 percent higher than the TITAN V's average, but that is entirely due to the TITAN V's weak G2D test. In any test that measures 3D rendering or compute, the TITAN V would win by an enormous margin.
