The NVIDIA GeForce GT 630M is a GeForce 600M-generation mobile GPU built around the GF117 chip and Fermi 2.0 architecture. TSMC manufactures the 28 nm die, which contains 585 million transistors across a 116 mm² footprint, for a transistor density of 5.0M/mm². Released on 2012-03-21, it sits between the GeForce 500M and GeForce 700M generations and is now end-of-life. The only benchmark listing is a Geekbench OpenCL score of 2367, placing the GT 630M at the 13th percentile of all GPUs.
Benchmark Performance
The GT 630M's average benchmark score is 2367, identical to its Geekbench OpenCL result. At the 13th percentile, it ranks below the large majority of GPUs in the database. The nearest listed rivals cluster tightly around this score. The Quadro M1000M trails at 2326, giving the GT 630M a deltaPct of 1.8, its largest positive margin in the rival set. The GeForce GT 550M scores 2363, a deltaPct of 0.2, meaning the GT 630M is effectively tied with it. The GeForce MX150 is slightly ahead at 2377, with the GT 630M showing a deltaPct of -0.4. The AMD Radeon RX 6750 GRE 12 GB leads the group at 2402, where the deltaPct is -1.5. These deltas are small, so the single OpenCL workload does not separate the GT 630M from its nearest competitors by a meaningful margin.
The compute context behind that score is a 240.0 GFLOPS FP32 rate, a 2.500 GPixel/s pixel rate, and a 10.00 GTexel/s texture rate. The specification lists 96 shading units, 16 texture mapping units, and 4 ROPs. No base or boost clock is listed; only the memory clock is provided. That makes clock-for-clock analysis impossible, but the benchmark score still defines its position. In this data, the GT 630M is a low-tier part with near-neighbor results within 1.8% in either direction.
Ray Tracing and Feature Set
The GT 630M has no RT core count and no tensor core count in its specification; both fields are null. This means there are no dedicated ray tracing or tensor processing units in the GPU. The API list includes DirectX 12 (11_0) and OpenGL 4.6, while Vulkan is not listed. DirectX 12 is therefore present in the specific 11_0 feature-level form rather than as a hardware ray tracing path. The Fermi 2.0 architecture, built on TSMC's 28 nm process, provides a conventional graphics pipeline rather than a ray-accelerated one. Users who need features that require dedicated RT or tensor hardware will not find them here. The stated feature support is limited to the listed DirectX and OpenGL APIs, with no Vulkan entry.
How It Compares
Against the GeForce GT 550M, the GT 630M scores 2367 versus 2363, a deltaPct of 0.2. The two are effectively tied, with the GT 630M holding a marginal edge.
Against the GeForce MX150, the GT 630M records 2367 versus 2377, a deltaPct of -0.4. The MX150 is ahead, but the gap is very small and places both GPUs in a similar performance neighborhood.
Against the AMD Radeon RX 6750 GRE 12 GB, the GT 630M trails 2367 to 2402, a deltaPct of -1.5. This is the largest deficit among the listed rivals, although the numerical distance remains modest.
Against the Quadro M1000M, the GT 630M leads 2367 to 2326, a deltaPct of 1.8. This is the largest positive margin in the nearest-rival list.
Power and Cooling
The GT 630M is specified with a TDP of 33 W, a low figure consistent with its MXM Module form factor. The slot width is listed as MXM Module, and the bus interface is MXM-A (3.0). No power connectors are required, meaning the module draws power through the MXM socket. No suggested PSU is listed in the data. Display outputs are portable-device dependent, so connectivity is determined by the host system. As a mobile module, the thermal solution is also dictated by the laptop orMXM carrier rather than by an add-in board design.
Who Should Consider It
At the 13th percentile and with 240.0 GFLOPS of FP32 compute, the GT 630M is positioned for modest or older workloads rather than high-end rendering. Its 2.500 GPixel/s pixel rate and 10.00 GTexel/s texture rate set a low ceiling for fill-rate-bound scenes. Users constrained to an MXM-A (3.0) slot who need a 33 W module without extra power connectors are the natural audience. The benchmark data shows a near tie with the GeForce GT 550M and only a 0.4% gap behind the GeForce MX150, so there is no meaningful performance jump between those entries. The Radeon RX 6750 GRE 12 GB and MX150 are ahead in the listed scores, but only by 1.5% and 0.4%, respectively. No resolution-specific or settings-specific benchmark data is included, so precise presets cannot be derived. The relative scores and the 1024 MB frame buffer instead suggest lower-resolution, lighter-detail use.
Memory Subsystem
The GT 630M has 1024 MB of GDDR5 memory on a 128-bit bus. Memory bandwidth is listed at 64.00 GB/s. The memory clock is 1000 MHz, which the specification records as 4 Gbps effective. A 128-bit bus is narrow, and 64.00 GB/s places a moderate cap on how quickly texture data can move. Combined with only 4 ROPs, high-resolution fill-rate work is constrained. The 1024 MB allocation means workloads that exceed that capacity must rely on system-level memory management. These memory specifications are consistent with the GPU's 13th-percentile benchmark position.
