NVIDIA GeForce GTX 675MX Specifications

GeForce GTX 675MX GPU Core

Shader units and compute resources

The NVIDIA GeForce GTX 675MX GPU core specifications define its raw processing power for graphics and compute workloads. Shading units (also called CUDA cores, stream processors, or execution units depending on manufacturer) handle the parallel calculations required for rendering. TMUs (Texture Mapping Units) process texture data, while ROPs (Render Output Units) handle final pixel output. Higher shader counts generally translate to better GPU benchmark performance, especially in demanding games and 3D applications.

About NVIDIA GeForce GTX 675MX

The NVIDIA GeForce GTX 675MX is a mobile graphics processor built on the Kepler architecture, fabricated on TSMC's 28nm process. The GK104 chip packs 3,540 million transistors into a 294 mm² die, yielding a transistor density of 12.0 million per square millimeter. It features 960 shading units, 80 texture mapping units, and 32 raster output units, achieving a pixel rate of 13.08 GPixel/s, a texture rate of 52.32 GTexel/s, and a FP32 compute throughput of 1,255.7 GFLOPS. With a memory clock of 900 MHz (3.6 Gbps effective) and a 256-bit bus, it delivers 115.2 GB/s of bandwidth from 2 GB of GDDR5 memory. The GPU posts an average benchmark score of 8094 across Geekbench Metal and OpenCL tests, placing it at the 41st percentile of all GPUs in the database.

How It Compares

The GeForce 945M scores 8099, a mere 0.1% higher than the 675MX. The delta of -0.1% means the 675MX is effectively tied with the 945M in these benchmarks. The 5-point difference is well within run-to-run variance, so the two GPUs can be considered performance peers. Users moving between these parts would see no meaningful change in the measured workloads.

The GRID K2, with an average score of 8075, trails the 675MX by 0.2%. This places the 675MX slightly ahead, though the 19-point margin is too small to confer any real-world advantage. The GRID K2 is a data-center-oriented part, but in these Geekbench tests, the mobile 675MX holds a marginal edge. The difference is statistically negligible, yet the 675MX does come out on top.

The GTX 970 scores 8024, which is 0.9% lower than the 675MX. The 70-point gap is more noticeable but still modest. The 675MX outperforms the GTX 970 in the averaged Geekbench tests, though the latter is a desktop GPU with a different thermal and power profile. The 0.9% advantage is consistent across the two benchmark runs, suggesting a small but repeatable lead.

Similarly, the GTX 650 Ti scores 8018, also 0.9% behind. The 76-point difference gives the 675MX a slight but consistent advantage. Across the four nearest rivals, the 675MX sits in the middle: it is slightly slower than the 945M, but faster than the GRID K2, GTX 970, and GTX 650 Ti. With a percentile of 41, the 675MX sits below the median of the database, but it is not an entry-level part either.

Ray Tracing and Feature Set

The specification sheet for the GTX 675MX does not list any ray tracing cores or tensor cores. This is consistent with its Kepler architecture, which relies on traditional rasterization for rendering. Consequently, any ray-traced effects would need to be computed in software, which would severely impact performance. The GPU supports DirectX 12 with a feature level of 11_0, meaning it can run DirectX 12 titles but only with the feature set of DirectX 11. It also supports OpenGL 4.6 and Vulkan 1.2.175, both of which are modern APIs that allow for cross-platform development. The lack of dedicated RT hardware means that the 675MX is not suited for ray-traced gaming, but it remains compatible with a wide range of existing titles. The Vulkan 1.2.175 support is particularly relevant for open-standard engines, and the OpenGL 4.6 support ensures compatibility with many professional applications.

Who Should Consider It

The GTX 675MX is best suited for users who need a mobile GPU with moderate performance. Its average score of 8094 places it at the 41st percentile, meaning it outperforms 41% of all GPUs in the database. It is closely matched to the GeForce 945M and GTX 650 Ti, both of which are commonly found in mid-range laptops. For gaming, the 2 GB GDDR5 memory and 256-bit bus provide sufficient bandwidth for 1080p resolutions in titles that are not excessively demanding. However, the lack of dedicated ray tracing hardware and the DirectX 12 feature level 11_0 limit its ability to handle the latest effects at high settings. Users who prioritize older DirectX 11 games or esports titles will find it adequate. The support for Vulkan 1.2.175 also ensures compatibility with modern open-standard games. Given its end-of-life production status, it is more relevant for existing laptop owners than for new system builders. The MXM form factor means it is not a drop-in upgrade for desktop systems, but rather a component that fits into a laptop's MXM-B (3.0) slot.

Power and Cooling

The GTX 675MX has a TDP of 100 W, which is moderate for a mobile GPU. It is designed as an MXM module, meaning it slots into a laptop's MXM-B (3.0) interface. The specification lists no power connectors, indicating that the host laptop provides power through the MXM slot itself. This simplifies installation and reduces cable clutter, but it also means that the laptop's cooling solution must be capable of dissipating 100 W of heat. The absence of a suggested PSU figure is expected, as power delivery is handled by the laptop's power supply and motherboard. Users should ensure their laptop's thermal design can handle the sustained load. The lack of external power connectors also implies that the GPU is not intended for desktop adapters, reinforcing its mobile-only nature.

Memory Subsystem

The GTX 675MX is equipped with 2 GB of GDDR5 memory connected via a 256-bit bus. The memory operates at 900 MHz, translating to 3.6 Gbps effective data rate, and provides a total bandwidth of 115.2 GB/s. This bandwidth is sufficient for 1080p gaming with moderate texture detail. The 256-bit bus width is notably wide for a mobile GPU, which helps maintain throughput at higher resolutions. However, the 2 GB capacity may become a limiting factor in modern games that exceed 2 GB of VRAM usage at high settings or with high-resolution texture packs. For the performance level indicated by its benchmark scores, the memory subsystem is well balanced, offering enough bandwidth to avoid bottlenecks in the GPU's compute capabilities. The pixel rate of 13.08 GPixel/s and texture rate of 52.32 GTexel/s further indicate that the memory interface is matched to the shading and texture throughput, preventing any single component from becoming a clear constraint in typical workloads.
