About NVIDIA GeForce GT 755M
The NVIDIA GeForce GT 755M is a Kepler-architecture mobile GPU built on TSMC's 28 nm process, containing 1,270 million transistors across a 118 mm² die. Released on June 24, 2013, it is now end-of-life, and its average benchmark score of 4033 places it at the 23rd percentile of all GPUs in the database. This places it firmly in the entry-level segment, with performance that is nearly identical to a cluster of older workstation and desktop cards.
Benchmark Performance
The GT 755M's average score of 4033 is only 0.1% higher than the NVIDIA Quadro K2000 (4028), making the two effectively interchangeable in raw compute. It leads the AMD Radeon HD 6850 X2 (3977) by 1.4%, the NVIDIA Quadro 2000D (3930) by 2.6%, and the NVIDIA Quadro K2000D (3919) by 2.9%. These deltas are small enough that real-world differences would be negligible in most workloads. In Geekbench, the card scores 3132 in the Metal test and 4934 in the OpenCL test, indicating that its OpenCL performance is roughly 57% higher than its Metal result, a typical pattern for GPUs of this era. Given the 23rd percentile ranking, the GT 755M is outclassed by more than three-quarters of all GPUs in the database, but it still holds its own against the specific rivals listed, all of which sit within a 3% performance band.
The FP32 compute rating of 783.4 GFLOPS, combined with a texture rate of 32.64 GTexel/s and a pixel rate of 8.160 GPixel/s, provides a baseline for expected throughput. These figures are consistent with a GPU designed for 1080p gaming at low to medium settings in titles from its release period, but they are far below what modern games require. The benchmark data does not include any gaming-specific tests, so the scores should be interpreted as general compute performance, not frame rates.
Ray Tracing and Feature Set
The GT 755M has no dedicated ray tracing cores and no tensor cores. This is a Kepler-generation GPU from 2013, long before hardware-accelerated ray tracing became a standard feature. Consequently, any ray tracing workload would have to be handled by the shader units, which number 384. The card supports DirectX 12 (11_0), meaning it can run DirectX 12 applications but only at feature level 11_0, which omits many modern DX12 features such as mesh shaders and variable rate shading. OpenGL 4.6 and Vulkan 1.2.175 are also supported, giving it access to current graphics APIs, albeit with limited hardware capabilities.
The absence of tensor cores also rules out any AI-accelerated features like DLSS or similar upscaling. For a GPU of this class, the feature set is limited to traditional rasterization and compute. The API support is surprisingly broad for a 2013 part, but the hardware itself cannot take advantage of the latest API extensions. The 384 shading units and 32 TMUs are the workhorses, and they will be the bottleneck in any modern workload.
Memory Subsystem
The GT 755M is equipped with 2 GB of GDDR5 memory on a 128-bit bus, yielding a memory bandwidth of 86.40 GB/s. The memory clock is 1350 MHz, which translates to 5.4 Gbps effective. This bandwidth is modest by today's standards, and 2 GB of VRAM is insufficient for high-resolution textures or modern game assets. At 1080p, the card may cope with older titles, but at 1440p or higher, the bandwidth and capacity will severely limit performance. The 128-bit bus width is a common configuration for entry-level GPUs, and it directly constrains the memory bandwidth to a level that is roughly half of what mid-range cards of the same era offered.
For compute workloads that rely on memory access, the 86.40 GB/s figure will be a limiting factor. The card's pixel rate of 8.160 GPixel/s is also tied to the ROP count (16) and the core clock, and it is consistent with a GPU that is not designed for high-resolution output. The 2 GB frame buffer is adequate for 1080p gaming with reduced texture quality, but it will be exhausted quickly by modern games that often require 4 GB or more.

How It Compares
NVIDIA Quadro K2000 — The K2000 is the closest rival, with an average score of 4028 against the GT 755M's 4033, a delta of just 0.1%. This means the two GPUs are essentially identical in compute performance. The K2000 is a workstation card, while the GT 755M is a mobile part, but their benchmark results are interchangeable.
AMD Radeon HD 6850 X2 — The HD 6850 X2 scores 3977, which is 1.4% lower than the GT 755M. This is a dual-GPU desktop card from AMD, yet the single mobile GPU from NVIDIA manages to outperform it by a small margin. The delta is within run-to-run variance, so the practical difference is minimal.
NVIDIA Quadro 2000D — With a score of 3930, the Quadro 2000D trails the GT 755M by 2.6%. The Quadro 2000D is a professional card, but its older architecture and lower clock speeds put it slightly behind the GT 755M in raw compute.
NVIDIA Quadro K2000D — The K2000D scores 3919, a 2.9% deficit relative to the GT 755M. Like the other Quadro cards, it is aimed at professional workloads, but its performance is marginally lower than the GT 755M's. All four rivals fall within a 3% band, making the GT 755M the fastest of the group, but only by a small margin.
Who Should Consider It
The GT 755M is suitable for users who need basic 3D acceleration for older games or light productivity tasks at 1080p resolution. Its 2 GB VRAM and 86.40 GB/s bandwidth are enough for esports titles or games from around 2013–2015 at low to medium settings. The 23rd percentile ranking indicates that it is not capable of handling modern AAA games, which typically require far more compute and memory bandwidth. For users who primarily run legacy software or are constrained to a laptop with an MXM slot, the GT 755M offers a modest upgrade over integrated graphics, but it will not satisfy gamers seeking high frame rates.
The card's performance relative to its rivals — all within 3% — suggests that it is a solid entry-level option for its time. However, the lack of ray tracing and tensor cores means it cannot leverage modern features like DLSS, and its DirectX 12 support is limited to feature level 11_0. For anyone considering this GPU today, the use case is narrow: it is best suited for retro gaming, basic media playback, or as a display adapter for office work. At higher resolutions or with demanding modern software, the 2 GB memory capacity and 86.40 GB/s bandwidth will quickly become bottlenecks.
Power and Cooling
The GT 755M has a TDP of 50 W, which is remarkably low for a discrete GPU. It is designed as an MXM module, meaning it is intended for laptop or small-form-factor systems where space and thermal limits are tight. The card requires no external power connectors, drawing all its power from the MXM slot itself. No suggested PSU is listed, but given the 50 W TDP, a standard laptop power adapter or a desktop PSU with a PCIe slot would suffice. The low power draw also means that cooling requirements are modest; a simple heat pipe or small fan is typically enough to keep the GPU within operating temperatures. This makes the GT 755M an attractive option for systems where power efficiency is a priority, though its performance ceiling is correspondingly limited.
