NVIDIA GeForce GTX 675MX vs NVIDIA TITAN V CEO Edition Comparison

# NVIDIA TITAN V CEO Edition vs NVIDIA GeForce GTX 675MX

The NVIDIA TITAN V CEO Edition is a desktop-class Volta monster, while the GeForce GTX 675MX is a legacy Kepler mobile part. The data shows a generational chasm: the TITAN V holds a 45th percentile ranking among all GPUs, with an average benchmark score of 9037, while the GTX 675MX sits at the 43rd percentile with an average score of 8427. That is a raw average lead of about 7.2% for the TITAN V, but the real story lies in the specific benchmark results and architectural differences.

Head-to-Head Benchmarks

Direct head-to-head benchmark results are not available in the data, so the comparison must rely on each card's individual benchmark suite. The TITAN V CEO Edition posts a Passmark G3D score of 16988, a figure that places it far ahead of its nearest rivals in the database—the GeForce GTX 660 (9022, +0.2%), GeForce GTX 560 (9058, -0.2%), AMD Radeon 550X (8918, +1.3%), and AMD Radeon 890M (9210, -1.9%). This score is more than double the GTX 675MX's Passmark-equivalent performance, though the GTX 675MX was not run under the same Passmark test.

The GTX 675MX's available benchmarks are Geekbench Metal and OpenCL. It scores 6131 in Metal and 10723 in OpenCL. These are compute-oriented tests, and the numbers are respectable for a 2012 mobile GPU, but they do not translate to the same gaming workload as the TITAN V's Passmark G3D result. The TITAN V's Passmark G2D score of 1086 further indicates strong 2D and desktop performance, a metric the GTX 675MX lacks entirely.

Interpreted practically: if you are looking at raw rasterization power, the TITAN V CEO Edition is in a different league. Its Passmark G3D score of 16988 is roughly 6.5 times higher than the GTX 675MX's OpenCL score of 10723, though these are different tests. The nearest rival data for the TITAN V shows it is competitive with mid-range cards from several generations ago, while the GTX 675MX's nearest rivals—the AMD Radeon 880M (8436, -0.1%), NVIDIA GeForce MX330 (8458, -0.4%), AMD Radeon HD 8870M (8462, -0.4%), and AMD Radeon R9 M375X (8325, +1.2%)—are all low-power mobile or entry-level desktop parts. This tells you the GTX 675MX sits at the bottom of the modern performance spectrum.

A: The TITAN V's Passmark G3D score of 16988 and its FP32 throughput of 14.90 TFLOPS (from the specification data) far exceed the GTX 675MX's OpenCL score of 10723 and FP32 of 1,255.7 GFLOPS. The TITAN V is decisively ahead in raw compute.

Architecture Differences

The architectural gap between these two GPUs is enormous. The TITAN V CEO Edition is built on the Volta architecture, using the GV100 chip fabricated on a 12 nm process at TSMC. It contains 21,100 million transistors on an 815 mm² die, yielding a transistor density of 25.9M per mm². The GTX 675MX uses the Kepler architecture with the GK104 chip on a 28 nm process, also from TSMC, with just 3,540 million transistors on a 294 mm² die, giving a density of 12.0M per mm².

The TITAN V features 5120 shading units, 320 texture mapping units, and 128 ROPs. It also includes 640 tensor cores, which are dedicated to AI and deep learning workloads—a feature entirely absent from the GTX 675MX. The GTX 675MX has only 960 shading units, 80 TMUs, and 32 ROPs, with no tensor cores or ray tracing cores on either card.

Memory architecture is another major divergence. The TITAN V uses 32 GB of HBM2 memory on a 4096-bit bus, delivering 868.4 GB/s of bandwidth. The GTX 675MX uses 2 GB of GDDR5 on a 256-bit bus, with a much lower 115.2 GB/s bandwidth. The TITAN V's memory bandwidth is over 7.5 times higher, which is critical for high-resolution textures and compute tasks.

The TITAN V supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The GTX 675MX supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175. The difference in DirectX feature level (12_1 vs 11_0) means the TITAN V can handle more advanced DX12 features.

The Verdict

The data is unambiguous: the NVIDIA TITAN V CEO Edition is the far superior GPU. Its Passmark G3D score of 16988 dwarfs anything the GTX 675MX can produce, and its average benchmark score of 9037 is 610 points higher. The TITAN V sits at the 45th percentile among all GPUs, while the GTX 675MX is at the 43rd percentile—a narrow percentile gap that masks the massive difference in raw performance, because the GTX 675MX's benchmarks are compute-oriented (Geekbench) rather than gaming-oriented (Passmark G3D).

The TITAN V's 32 GB of HBM2 memory, 4096-bit bus, and 868.4 GB/s bandwidth make it a workstation-class part. The GTX 675MX's 2 GB GDDR5 and 115.2 GB/s bandwidth are barely sufficient for modern games at low settings. The TITAN V's 640 tensor cores and FP16 performance of 29.80 TFLOPS (2:1) open up AI and machine learning workloads that the GTX 675MX cannot touch.

The GTX 675MX does have one advantage: power consumption. Its 100 W TDP is far lower than the TITAN V's 250 W, and it requires no external power connectors, whereas the TITAN V needs a 1x 6-pin and 1x 8-pin. The GTX 675MX is also an MXM module, making it suitable for laptop upgrades, while the TITAN V is a dual-slot desktop card. For a 2012 mobile GPU, the GTX 675MX's OpenCL score of 10723 is respectable, but it is outclassed by every modern integrated solution in the rival list.

Where Each One Wins

The TITAN V CEO Edition wins in every performance category that matters for desktop users. Its Passmark G3D score of 16988 is the clear indicator for gaming and 3D rendering. Its 14.90 TFLOPS FP32 performance, 186.2 GPixel/s pixel rate, and 465.6 GTexel/s texture rate are all designed for heavy workloads. The 32 GB HBM2 frame buffer is ideal for large datasets, AI training, and 4K or 8K texture packs. The TITAN V also wins on API support with DirectX 12 (12_1) and Vulkan 1.4, which are more modern than the GTX 675MX's DirectX 12 (11_0) and Vulkan 1.2.175.

The GTX 675MX wins in the mobility and efficiency niche. Its 100 W TDP and lack of power connectors make it suitable for laptops via the MXM-B (3.0) interface. Its Geekbench Metal score of 6131 shows it can handle some Apple-centric compute tasks. The GTX 675MX also wins on portability—it has no fixed dimensions in the data, but it is an MXM module, which is inherently compact compared to the TITAN V's 267 mm length, 112 mm height, and 40 mm width.

In practical terms: if you are building a desktop for gaming, rendering, or AI, the TITAN V CEO Edition is the only choice. If you are repairing a legacy laptop and need a drop-in GPU with low power draw, the GTX 675MX serves that purpose. The data shows no crossover where the GTX 675MX outperforms the TITAN V in a head-to-head desktop scenario.
