AMD Radeon R9 M375X vs NVIDIA TITAN V CEO Edition Comparison

The NVIDIA TITAN V CEO Edition and AMD Radeon R9 M375X represent two entirely different eras and performance classes of GPU hardware. The TITAN V is a 2018 flagship built on Volta architecture with a massive 21,100 million transistors, while the R9 M375X is a 2015 mobile-oriented chip based on GCN 1.0 with just 1,500 million transistors. The benchmark data reflects this gulf, though the two cards actually land surprisingly close in the overall percentile rankings, with the TITAN V at 45 and the R9 M375X at 43.

Head-to-Head Benchmarks

The most striking comparison comes from the raw compute capabilities. The TITAN V CEO Edition delivers 14.90 TFLOPS of FP32 performance, which is roughly 11.5 times higher than the R9 M375X's 1,299.2 GFLOPS. This translates directly into a massive advantage in any compute-heavy workload, scientific simulation, or rendering task. The TITAN V also boasts 5,120 shading units versus 640 on the R9 M375X, an 8:1 ratio that explains the enormous throughput difference.

Memory bandwidth tells a similarly lopsided story. The TITAN V features 32 GB of HBM2 memory on a 4096-bit bus, yielding 868.4 GB/s of bandwidth. The R9 M375X is limited to 2 GB of GDDR5 on a 128-bit bus, providing just 72.00 GB/s. That is a 12x difference in bandwidth, which means the TITAN V can feed its shaders far more effectively in texture-heavy scenes or large dataset operations. The TITAN V's texture rate of 465.6 GTexel/s dwarfs the R9 M375X's 40.60 GTexel/s, and the pixel rate difference is equally stark at 186.2 GPixel/s versus 16.24 GPixel/s.

However, the aggregated benchmark scores tell a more nuanced story. The TITAN V scores 16,988 in Passmark G3D, while the R9 M375X has no Passmark score listed. Instead, the R9 M375X posts 8,273 in Geekbench OpenCL and 8,377 in Geekbench Vulkan. The average benchmark score for the TITAN V is 9,037, while the R9 M375X averages 8,325. This puts the TITAN V only about 8.6% ahead in average score, a surprisingly small margin given the enormous architectural differences.

The nearest rivals data clarifies this anomaly. The TITAN V's average score of 9,037 places it within 0.2% of the NVIDIA GeForce GTX 660 (9,022) and within -0.2% of the GTX 560 (9,058). It also sits 1.3% above the AMD Radeon 550X (8,918) and 1.9% below the AMD Radeon 890M (9,210). This suggests that the average benchmark score, which likely weights a broad range of tests, does not fully capture the TITAN V's peak capabilities. The R9 M375X, with its 8,325 average, is 0.7% above the NVIDIA Quadro K1200 (8,265), 1.2% below the GeForce GTX 675MX (8,427), 1.3% below the AMD Radeon 880M (8,436), and 1.6% below the GeForce MX330 (8,458).

The Passmark G2D score for the TITAN V is 1,086, which reflects its 2D desktop performance. The R9 M375X has no comparable 2D score in the data. In terms of pure compute, the TITAN V's FP16 capability of 29.80 TFLOPS (2:1 ratio) is another differentiator, as the R9 M375X has no listed FP16 performance. The TITAN V also includes 640 tensor cores, a feature entirely absent from the R9 M375X, which has no tensor core count listed.

The Verdict

The data makes it clear that the NVIDIA TITAN V CEO Edition is the superior performer in almost every measurable specification. Its FP32 compute of 14.90 TFLOPS, memory bandwidth of 868.4 GB/s, and 32 GB of HBM2 memory place it in a completely different performance tier than the R9 M375X. Anyone running compute-intensive workloads, large neural networks (given the 640 tensor cores), or high-resolution texture-heavy applications would need the TITAN V's resources.

However, the average benchmark scores tell a more complicated story. With a 45th percentile ranking versus 43rd for the R9 M375X, the TITAN V is not dramatically ahead in the aggregated cross-section of tests that produce these averages. The TITAN V's nearest rivals include the GTX 660 and GTX 560, both much older and less capable cards on paper, which suggests that the average score may be weighted toward legacy or less demanding workloads. The R9 M375X, meanwhile, is competitive with the Quadro K1200 and GTX 675MX, indicating it holds its own in its own performance class.

For a user choosing between these two, the decision hinges entirely on workload. If the task involves modern AAA gaming at high resolutions, GPU compute, or AI inference, the TITAN V's 14.90 TFLOPS and 29.80 TFLOPS FP16 performance are decisive. The R9 M375X, with only 1,299.2 GFLOPS FP32 and no listed FP16 or tensor cores, would struggle with these tasks. For basic desktop use or legacy applications, the R9 M375X's 8,325 average score might suffice, but the TITAN V's 9,037 average still leads, and its 12x bandwidth advantage ensures smoother operation in memory-bound scenarios. The data consistently favors the TITAN V, making it the clear pick for any demanding workload.

Specification Differences

The two GPUs differ in nearly every core specification. The TITAN V uses a 12 nm process from TSMC with 21,100 million transistors on an 815 mm² die, while the R9 M375X uses a 28 nm process with 1,500 million transistors on a 123 mm² die. Clock speeds differ substantially: the TITAN V runs at 1200 MHz base and 1455 MHz boost, while the R9 M375X runs at 925 MHz base and 1015 MHz boost.

Memory configurations are completely different. The TITAN V has 32 GB of HBM2 on a 4096-bit bus with 868.4 GB/s bandwidth. The R9 M375X has 2 GB of GDDR5 on a 128-bit bus with 72.00 GB/s bandwidth. The TITAN V's memory clock is 848 MHz (1696 Mbps effective), while the R9 M375X has a 1125 MHz memory clock (4.5 Gbps effective).

The shading units, texture mapping units, and raster operations pipelines are all vastly different. The TITAN V has 5,120 shading units, 320 TMUs, and 128 ROPs. The R9 M375X has 640 shading units, 40 TMUs, and 16 ROPs. The TITAN V also includes 640 tensor cores, while the R9 M375X has no tensor cores listed.

The TITAN V has a TDP of 250 W, requires a 600 W suggested PSU, uses a dual-slot form factor with 1x 6-pin + 1x 8-pin power connectors, and measures 267 mm in length, 112 mm in height, and 40 mm in width. The R9 M375X has no TDP, PSU, slot width, power connector, or dimension information listed. The TITAN V offers 1x HDMI 2.0 and 3x DisplayPort 1.4a outputs, while the R9 M375X has no display output information.

Architecture Differences

The architectural divide is fundamental. The TITAN V is built on NVIDIA's Volta architecture, while the R9 M375X uses AMD's GCN 1.0 architecture. The TITAN V's GV100 chip is a massive 815 mm² design fabricated on TSMC's 12 nm node, achieving a transistor density of 25.9M per mm². The R9 M375X's Tropo chip is a much smaller 123 mm² design on TSMC's 28 nm node, with a density of just 12.2M per mm².

The TITAN V represents the GeForce 10 generation and succeeds the GeForce 900 series, with the GeForce 20 series as its successor. The R9 M375X belongs to the Gem System (R9 M300) generation, with the Solar System as its predecessor and Polaris Mobile as its successor. The TITAN V supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, while the R9 M375X supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170.

The TITAN V's feature set includes 640 tensor cores for AI acceleration and FP16 performance of 29.80 TFLOPS at a 2:1 ratio, capabilities absent from the R9 M375X, which has no FP16 or tensor core specifications listed. The TITAN V also offers FP32 compute of 14.90 TFLOPS versus 1,299.2 GFLOPS for the R9 M375X. The pixel rate is 186.2 GPixel/s for the TITAN V and 16.24 GPixel/s for the R9 M375X, while the texture rate is 465.6 GTexel/s versus 40.60 GTexel/s. Both cards use a PCIe 3.0 x16 bus interface, but the TITAN V's power delivery system includes dual connectors and a 600 W suggested PSU, highlighting its much higher power requirements as a desktop flagship.
