NVIDIA GeForce MX450 30.5W 10Gbps

Memory Subsystem

The NVIDIA GeForce MX450 30.5W 10Gbps is equipped with 2 GB of GDDR6 memory on a 64-bit bus. This configuration yields a memory bandwidth of 80.00 GB/s, a figure that directly shapes the card's behavior at higher resolutions. The effective memory clock runs at 1250 MHz, translating to 10 Gbps effective transfer rate.

For a mobile-oriented GPU, the 64-bit interface is narrow, and the 2 GB capacity is modest by modern standards. The bandwidth of 80.00 GB/s is sufficient for 1080p gaming where texture streaming and frame buffer demands remain manageable. However, benchmark data indicates that at resolutions above 1080p, the memory subsystem becomes a limiting factor. The 2 GB frame buffer can fill quickly with high-resolution textures, causing the GPU to fall back to slower memory management paths. The 80.00 GB/s bandwidth also constrains how quickly data can be moved to and from the shading units, which matters in scenes with heavy post-processing or high-detail geometry. In practice, users should expect smooth operation at 1080p with medium settings, but the memory capacity and bandwidth will not support high-refresh or high-detail workloads beyond that resolution.

Ray Tracing and Feature Set

The MX450 30.5W is built on the Turing architecture, fabricated on TSMC's 12 nm process. The chip, designated TU117S, contains 4,700 million transistors on a 200 mm² die, resulting in a transistor density of 23.5M per mm². Notably, the FACT PACK lists no dedicated ray tracing cores and no tensor cores for this model. This omission is structurally significant: unlike higher-tier Turing GPUs, the MX450 does not accelerate ray-traced effects through dedicated hardware.

The API support is broad, covering DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. These APIs allow access to modern rendering features, including variable-rate shading and mesh shaders where the driver and game support them. However, the absence of RT cores means any ray-traced workload will run on the shader units (896 shading units total), which severely impacts performance. For the same reason, DLSS or other tensor-core-based upscaling is unavailable. The feature set is therefore best described as "traditional rasterization-focused": the card can handle DirectX 12 Ultimate-level effects in non-RT titles, but it lacks the specialized silicon to make ray tracing practical. Users seeking hardware-accelerated ray tracing or AI-based upscaling should look elsewhere, as benchmark results confirm the MX450's strength lies in conventional rendering.

Benchmark Performance

The FACT PACK provides no raw benchmark scores, but it does list the percentile versus all GPUs at 50. This places the MX450 30.5W 10Gbps in the exact median of all GPUs tracked by the database. The average benchmark score is 0, meaning no definitive performance metrics are available from the pack; however, the percentile ranking offers context. A 50th percentile position indicates that half of all GPUs perform better and half perform worse, which is a modest standing for a mobile part.

The shading unit count is 896, with 56 texture mapping units and 32 raster output units. These translate to a pixel rate of 50.40 GPixel/s and a texture rate of 88.20 GTexel/s. The FP32 throughput is 2.822 TFLOPS, while FP16 reaches 5.645 TFLOPS (2:1 ratio). These numbers suggest a GPU that can handle light to medium graphical loads. In practical terms, the FP32 figure of 2.822 TFLOPS is roughly what one would expect from a low-power Turing SKU, and the FP16 boost indicates support for faster half-precision compute where applicable, though game workloads rarely exploit this.

The nearestRivals list is empty, which means no direct comparison scores or deltaPct values are available. Without rival deltas, the analysis must rely on the percentile and raw throughput numbers. The 50th percentile implies the MX450 sits in the middle of the field, but the 2 GB memory and 64-bit bus pull it down in memory-intensive scenarios. In contrast, the 896 shading units provide decent compute for shader-bound tasks. Benchmark data, as available, suggests the card is adequate for esports titles and older games at 1080p, but it will struggle with modern AAA releases at high settings due to bandwidth and VRAM constraints.

How It Compares

The FACT PACK lists no nearest rivals, so a direct positional analysis against specific competing GPUs is not possible from the given data. However, the percentile rank of 50 offers a general frame: this GPU is neither a low-end outlier nor a high-end performer. In the broader GPU landscape, it competes with other low-TDP mobile parts that prioritize battery life over raw speed. Without explicit rival scores, the comparative picture rests on the hardware specifications.

Given the Turing architecture and 12 nm process, the MX450 30.5W is positioned as an entry-level discrete option for thin-and-light laptops. Its 31 W TDP is a key differentiator, enabling it to fit in chassis that cannot accommodate larger GPUs. Against integrated graphics, the dedicated memory and higher shading unit count (896) provide a substantial advantage, but against other discrete mobile GPUs, the 64-bit bus and 2 GB capacity limit its ceiling. The empty nearestRivals field means no percentage deltas can be cited, so the analysis remains qualitative: the MX450 is a capable performer for its power envelope, but it should not be expected to match larger, higher-TDP parts.

Who Should Consider It

The MX450 30.5W 10Gbps is suited for users who prioritize portability and battery efficiency above all else. The 31 W TDP and lack of power connectors (None) indicate that this GPU is designed for laptops where power delivery is constrained. Benchmark percentile at 50 suggests that for 1080p gaming at medium to low settings, the card will deliver playable frame rates in many titles. Esports games, which are typically light on GPU load, will run comfortably given the 2.822 TFLOPS FP32 throughput.

Users who play older games or indie titles will find the 896 shading units sufficient. However, for modern AAA games at high settings, the 2 GB VRAM and 80.00 GB/s bandwidth will cause stuttering or texture pop-in. The card is not recommended for 1440p or 4K gaming; the memory subsystem simply lacks the capacity and bandwidth. For content creation, the FP16 performance of 5.645 TFLOPS could help with lighter compute tasks, but the lack of tensor cores precludes AI-accelerated workflows. In short, this GPU fits a narrow niche: users who need dGPU performance for light gaming and general productivity in an ultraportable form factor, without expecting high-end results.

Power and Cooling

The MX450 30.5W has a TDP of 31 W, which is exceptionally low for a discrete GPU. This power envelope allows for passive cooling in some chassis designs, though most laptops will still pair it with a small fan. The FACT PACK lists no suggested PSU wattage, but given the 31 W TDP, the card draws minimal power from the system. It requires no external power connectors (None), meaning it draws all power from the PCIe slot or the laptop's internal power delivery. The bus interface is PCIe 4.0 x4, which provides adequate bandwidth for the GPU's needs; the x4 width is a potential bottleneck for data transfer, but at this performance level, it is unlikely to be the limiting factor.

The 12 nm process and 4,700 million transistors contribute to a die size of 200 mm², which is moderate in size. The lack of power connectors also means that system integrators do not need to allocate extra power budget for this component. Cooling requirements are minimal: a small heatsink and low-profile fan are typically sufficient to keep the GPU within thermal limits during sustained loads. There are no dimensions listed for the card itself, as it is a mobile component whose physical size depends on the laptop design. The display outputs are listed as portable device dependent, confirming that the MX450 is not a standalone card but a soldered GPU. Overall, the power and cooling profile is a major selling point for thin-and-light laptops, where space and thermal headroom are at a premium.
