NVIDIA GeForce 825M

Launched in early 2014 on the Kepler 2.0 architecture, the NVIDIA GeForce 825M is an end-of-life mobile graphics processor built for thin-and-light laptops. With a 28 nm TSMC process and a 1,020 million transistor count on an 87 mm² die, this chip sits at the entry level of the GeForce 800M generation. Benchmark data shows a single Geekbench OpenCL score of 3694, placing it at the 21st percentile of all GPUs — a figure that firmly establishes it as a legacy solution for basic computing rather than demanding gaming.

Benchmark Performance

The GeForce 825M’s average benchmark score of 3694 places it in a tight cluster of similarly aged entry-level parts. The data shows it is statistically tied with its closest rivals, all within a 1.5% margin. Against the NVIDIA GeForce GT 735M, the 825M leads by a mere 0.2%, with scores of 3694 versus 3687. The NVIDIA GeForce GT 740M is nearly identical, trailing by 0.3% with a score of 3683. The NVIDIA GeForce GT 545 sits 1.4% behind at 3643, while the only rival ahead in this group is the NVIDIA Quadro 3000M, which posts a 3752 score — a 1.5% advantage over the 825M.

The FP32 compute throughput of 722.7 GFLOPS, combined with a texture rate of 30.11 GTexel/s and a pixel rate of 7.528 GPixel/s, explains why this GPU clusters so tightly with its peers. These raw numbers indicate a part designed for basic acceleration, not high-frame-rate gaming. The 384 shading units and 32 TMUs provide enough parallel work for light workloads, but the 8 ROPs limit fill-rate-heavy tasks. In practical terms, the 825M will handle esports titles at low settings and 720p resolutions, but the benchmark percentile of 21% versus all GPUs confirms it is far below the median performance point of modern hardware. The deltas between rivals are so small — all under 2% — that any of these GPUs are interchangeable in real-world performance, with the 825M effectively sitting in the middle of a four-way tie.

Memory Subsystem

The memory configuration is a significant bottleneck for the GeForce 825M. It comes equipped with 1024 MB of DDR3 memory on a 64-bit bus, yielding a bandwidth of just 14.40 GB/s. The memory clock runs at 900 MHz, translating to 1800 Mbps effective. This is a stark limitation for high-resolution workloads where texture streaming and frame buffer bandwidth become critical.

At 1080p, the 14.40 GB/s bandwidth will cause stuttering and texture pop-in in modern 3D applications, as the GPU cannot feed its shading units fast enough. The 1 GB VRAM capacity is also restrictive, as many games from the mid-2010s onward require more than 1 GB for medium or high detail settings. The 64-bit bus width halves the data transfer path compared to mainstream 128-bit designs, which directly contributes to the low bandwidth figure. For the 825M, the memory subsystem is clearly the weakest link — the compute performance is modest, but the memory throughput severely caps any potential for playable frame rates at resolutions above 1366x768. This is a classic case where a small compute core is paired with an even smaller memory interface, making high-resolution gaming an unrealistic expectation.

Ray Tracing and Feature Set

The GeForce 825M does not include dedicated ray tracing cores or tensor cores, as these features were introduced in later architectures. Instead, this Kepler 2.0 chip relies on the standard CUDA core layout with 384 shading units. The API support reflects its era: DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175. The DirectX 12 (11_0) designation is particularly telling — it means the hardware supports DirectX 12 at the feature level 11_0, which lacks several modern rendering features like bindless resources and conservative rasterization.

For ray tracing, the absence of RT cores means hardware-accelerated ray tracing is entirely unavailable. Any ray-traced effects would have to be computed in software on the shading units, which is impractical given the 722.7 GFLOPS FP32 throughput. The Vulkan 1.2.175 support does allow for modern low-level API access, which can improve draw call efficiency, but it cannot overcome the fundamental hardware limitations. The lack of tensor cores also precludes any AI-accelerated features such as DLSS. The feature set here is purely functional: it supports the baseline APIs required for running older DirectX 11 titles and light Vulkan applications, but it offers nothing for next-generation graphics techniques.

FAQ

Q: How does the GeForce 825M compare to the GT 740M?

A: The 825M scores 3694, which is 0.3% higher than the GT 740M’s 3683. This is a negligible difference, making them effectively equal in performance.

Q: Can this GPU run games at 1080p?

A: The 14.40 GB/s memory bandwidth and 1 GB VRAM make 1080p gaming impractical for most 3D titles. The GPU is better suited for 720p or lower resolutions with reduced settings.

Q: Does the 825M support hardware ray tracing?

A: No. The chip lacks ray tracing cores, so hardware-accelerated ray tracing is not supported. Its DirectX 12 (11_0) feature level also limits modern rendering features.

Q: What is the TDP of this processor?

A: The thermal design power is 33 W, which is low enough for passively cooled or low-power laptops with an integrated form factor (IGP).

Q: Is the 825M faster than the Quadro 3000M?

A: No. The Quadro 3000M scores 3752, which is 1.5% higher than the 825M’s 3694. The 825M trails this rival, though the difference is small.

Q: Which API versions are supported?

A: The GPU supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175.

Who Should Consider It

The data indicates that the GeForce 825M is suitable only for users with very light graphics demands. The 21st percentile ranking versus all GPUs and the sub-3700 benchmark score mean this is not a gaming GPU by modern standards. Users should consider it for basic desktop composition, video playback, and legacy 2D applications. For gaming, the 825M can handle esports titles from the early 2010s at low settings and 720p, where the 30.11 GTexel/s texture rate is sufficient for simple scenes. The 1 GB VRAM and 14.40 GB/s bandwidth will struggle with any game that uses high-resolution textures or post-processing effects.

At 1366x768, which is the native resolution of most laptops from this era, the 825M can achieve playable frame rates in older titles like League of Legends or Counter-Strike: Global Offensive at low detail. However, the 0.2% to 1.4% delta against its nearest rivals means there is no reason to choose the 825M over a GT 735M or GT 740M if given the choice — they are all the same performance class. This GPU is a candidate only for basic productivity and media consumption, not for any serious 3D workload.

Power and Cooling

The GeForce 825M has a TDP of 33 W, which is remarkably low and allows for an integrated (IGP) slot width with no dedicated power connectors. This means it draws all its power from the motherboard slot and does not require any external power cabling. The absence of a suggested PSU rating in the data implies that the system’s existing power supply — typically a laptop adapter or a low-wattage desktop PSU — is sufficient. The 28 nm process node keeps thermals manageable, allowing for thin cooling solutions.

Given the 33 W TDP, cooling requirements are minimal. A single small heat pipe or even a passive heatsink in a well-ventilated chassis could theoretically handle this GPU, though most laptops pair it with a small fan. The lack of power connectors also simplifies system integration, making this a drop-in component for ultraportable designs. The 850 MHz base clock and 941 MHz boost clock contribute to the low power draw, as does the 64-bit memory bus which requires fewer I/O drivers. Users upgrading a laptop with this GPU should not worry about power delivery, but the performance ceiling is firmly set by the 33 W envelope.

How It Compares

NVIDIA GeForce GT 735M: The 825M leads the GT 735M by 0.2% (3694 vs 3687). This is a margin well within run-to-run variance, meaning the two are effectively identical. Users will see no meaningful difference in any workload.

NVIDIA GeForce GT 740M: The 825M is 0.3% faster than the GT 740M (3694 vs 3683). Again, this is a statistical tie. The GT 740M is often perceived as a slightly higher-tier part, but the benchmark data shows no real advantage.

NVIDIA GeForce GT 545: The 825M holds a 1.4% lead over the GT 545 (3694 vs 3643). The GT 545 is a desktop part from an older generation, yet the 825M edges it out. This shows the 825M is at least competitive with older entry-level desktop silicon.

NVIDIA Quadro 3000M: The Quadro 3000M is 1.5% faster than the 825M (3752 vs 3694). While the Quadro is a professional mobile GPU, its lead here is minimal. The 825M trails this rival but remains in the same performance bracket, which is notable given the Quadro’s typically higher price tier.
