NVIDIA GeForce GT 540M

NVIDIA's GeForce GT 540M is a legacy mobile graphics solution built on the Fermi architecture, occupying the 12th percentile of all GPUs in the database. Its Geekbench OpenCL score of 2165 places it in a tightly clustered group of older integrated and entry-level discrete parts, where the margin between it and its nearest rivals is measured in single-percentage-point differences. The data positions this chip as a baseline performer from its era, not a competitive option in any modern context.

Benchmark Performance

The GT 540M delivers an average benchmark score of 2165, which places it at the 12th percentile among all GPUs. This is a low standing, indicating that the overwhelming majority of contemporary and even older hardware outperforms it. The score itself comes from a single Geekbench OpenCL test, reflecting compute workload performance rather than gaming-specific metrics.

Against its nearest rivals, the performance deltas are extremely narrow. The GT 540M leads the NVIDIA NVS 5400M by just 0.1%, with scores of 2165 versus 2163, a statistical tie. It also edges out the Intel UHD Graphics 770 and the NVIDIA GeForce GT 620M, both of which score 2150, giving the GT 540M a 0.7% advantage in each case. The largest gap in this comparison group is against the Intel HD Graphics 4400, which scores 2142; here the GT 540M leads by only 1.1%.

These single-digit percentage differences are insignificant in real-world terms. The data shows that the GT 540M performs virtually identically to the NVS 5400M, a workstation-oriented counterpart, and is only marginally faster than the integrated graphics solutions from Intel that followed it by several generations. The 1.1% lead over the HD Graphics 4400 is the most substantial advantage in the group, yet it remains well within the margin of noise for typical benchmark variance. In essence, this GPU is the performance equal of entry-level integrated graphics from years later, which underscores its dated architecture.

Power and Cooling

The GT 540M carries a TDP of 35 watts, a modest figure that reflects its Fermi-era design and limited shader count. This low power draw means the chip generates relatively little heat, making it suitable for the MXM Module slot format it occupies. The slot width is specified as MXM Module, and the bus interface is MXM-A (3.0), indicating a removable laptop graphics card design rather than a soldered desktop part.

No power connectors are required for this GPU, as the 35 W TDP stays within what the MXM slot itself can supply. The system does not list a suggested PSU, which is consistent with mobile deployment where the laptop's power adapter handles all component supply. The absence of external power connectors simplifies integration into thin and light notebooks of its generation, but it also caps the available power for the GPU, reinforcing its entry-level positioning.

Cooling requirements for a 35 W part are minimal. The data does not specify a cooler size or type, but the thermal load is low enough that a basic heatpipe and fan assembly would suffice in most chassis. The production status is end-of-life, meaning no new units are being manufactured, and any cooling solutions are now legacy parts. Portable device dependent display outputs further confirm this is a mobile-only chip, designed to work within the constraints of laptop thermal envelopes.

Ray Tracing and Feature Set

The GT 540M has no dedicated ray tracing cores and no tensor cores, as these features did not exist in the Fermi architecture. Its API support includes DirectX 12 (11_0) and OpenGL 4.6, but Vulkan is not listed. The DirectX 12 support at the 11_0 feature level means the hardware is technically compatible with the DirectX 12 API but only implements the capabilities of the older DirectX 11 feature set.

This effectively rules out modern ray tracing workloads entirely. The rendering pipeline relies on 96 shading units, 16 texture mapping units, and 4 ROPs. The pixel rate is 2.688 GPixel/s and the texture rate is 10.75 GTexel/s, both figures that are extremely low by current standards. FP32 compute is rated at 258.0 GFLOPS, a number that modern integrated GPUs surpass by a wide margin.

For gaming, the feature set is limited to what Fermi could offer at the time: DirectX 11-class effects like tessellation and compute shaders, but nothing from the modern feature stack. The lack of Vulkan support also narrows compatibility with newer titles that rely on this API for cross-platform rendering. The 4 ROPs are a particular bottleneck, as they limit fill-rate performance in high-resolution scenarios, even if the shader cores are not fully saturated.

How It Compares

Against the NVIDIA NVS 5400M, the GT 540M leads by a razor-thin 0.1% margin, with scores of 2165 and 2163 respectively. These two GPUs are effectively identical in performance, which makes sense given their shared GF108 chip heritage. The NVS branding targets professional mobile workstations, but the benchmark data shows no meaningful compute advantage for either part.

The Intel UHD Graphics 770 trails by 0.7%, scoring 2150. This is a generational comparison where a much newer integrated GPU nearly matches a dedicated Fermi-era chip. The narrow delta indicates that Intel's modern iGPU has caught up to and essentially equaled this old discrete part in raw compute, despite the GT 540M having dedicated memory and a higher TDP.

The NVIDIA GeForce GT 620M also scores 2150, giving the GT 540M a 0.7% lead. As a direct successor in the same mobile lineup, the GT 620M was expected to improve on the GT 540M, but the data shows they are virtually indistinguishable in this benchmark. This suggests the architectural improvements between these generations were minimal in practice.

The Intel HD Graphics 4400 is the closest rival in percentage terms, scoring 2142, which puts the GT 540M 1.1% ahead. This older integrated solution from Intel's Haswell generation comes within a hair of the discrete GT 540M, highlighting how quickly integrated graphics closed the gap on low-end discrete parts.

Memory Subsystem

The GT 540M is equipped with 1024 MB of DDR3 memory, which was a standard capacity for entry-level mobile GPUs at its launch. The memory bus is 128 bits wide, and the memory clock runs at 900 MHz with an effective data rate of 1800 Mbps. This configuration yields a total bandwidth of 28.80 GB/s, a figure that is very low by contemporary standards.

For high-resolution gaming, this memory subsystem is a severe limitation. The 28.80 GB/s bandwidth means the GPU cannot quickly feed its 96 shading units with texture data and geometry, especially at resolutions above 1080p. The 1024 MB capacity is also a constraint, as modern games often require more video memory for high-resolution textures and detailed scenes, causing the GPU to spill into system memory via slower paths.

The 128-bit bus width is narrow, but it was typical for this class of GPU. The combination of DDR3 (rather than GDDR5) and a modest 900 MHz clock keeps power consumption low but caps bandwidth. In practical terms, the memory subsystem will bottleneck the already weak compute performance, making even medium settings at 1366x768 a challenge in newer titles. The pixel rate of 2.688 GPixel/s further compounds this, as the ROPs cannot fill frames quickly even when memory bandwidth is not the limiting factor.

Who Should Consider It

The GT 540M is not a GPU for modern gaming. Its 12th percentile ranking and Geekbench OpenCL score of 2165 indicate that it is only suitable for legacy applications or basic computing tasks. The data shows it performing on par with integrated graphics from later generations, which means any laptop with a modern iGPU would offer similar or better performance without the need for a discrete part.

For older games, particularly those released around 2011 or earlier, the GT 540M could handle low to medium settings at 720p or 1366x768 resolutions. The 1024 MB VRAM is sufficient for that era's titles, and the 28.80 GB/s bandwidth is adequate for simpler textures. Users with a soft spot for early DirectX 11 games might find this GPU usable, but the experience would be far from smooth by today's standards.

At 1080p, the GT 540M is out of its depth. The 2.688 GPixel/s pixel rate and 4 ROPs mean that even modest resolutions will tax the fill rate, and the limited bandwidth will cause stuttering in any game that requires streaming large textures. The GPU is best suited for non-gaming workloads: video playback, office productivity, and light photo editing are within its capabilities, though modern integrated graphics handle these tasks with lower power consumption and better efficiency. This is a part for historical interest or basic legacy systems, not for any current use case.
