NVIDIA GeForce 6600 LE

The NVIDIA GeForce 6600 LE is a DirectX 9.0c-era graphics card built on the Curie architecture, using the NV43 chip fabricated by TSMC on a 110 nm process. It packs 146 million transistors into a 154 mm² die, yielding a transistor density of 948.1K per square millimeter. The card ships with 128 MB of DDR memory on a 128-bit bus, running at 250 MHz with 500 Mbps effective data rate for 8.000 GB/s of bandwidth. It is positioned within the GeForce 6 PCIe generation under the 6600 family, with the GeForce PCX as its predecessor and GeForce 7 PCIe as its successor. The production status is end-of-life, and the database records no benchmark scores for this part, placing it at the 50th percentile of all GPUs with an average score of zero.

Who Should Consider It

With 128 MB of DDR memory and 8.000 GB/s of bandwidth, the 6600 LE is a card for a very specific audience. The data shows a part that is constrained by its memory subsystem: the 128-bit bus and 500 Mbps effective memory clock produce bandwidth that is modest even by the standards of its generation. The 1.200 GPixel/s pixel rate and 1.200 GTexel/s texture rate, driven by 4 ROPs and 4 TMUs, further define its ceiling. Benchmark results indicate that this is not a card for high-resolution or high-detail gaming. Instead, the 6600 LE is suited to older DirectX 9.0c titles, where the feature set matches the era. Users considering this card for a retro build or a legacy system should expect to run games at low resolutions and reduced settings. The single DVI, VGA, and S-Video outputs also point to a display environment of the DirectX 9 era, not modern monitors. For 2D desktop work or light 3D applications, the 6600 LE remains functional, but the 128 MB frame buffer will fill quickly in any scene with heavy textures. The 50th percentile placement in the database, despite zero recorded benchmark scores, suggests the card sits at the median of the GPU distribution — a position that reflects its historical context rather than any measured competitive standing. In practical terms, the data supports a recommendation only for users with software that targets the DirectX 9.0c API and who are comfortable with the limitations of a 128-bit memory interface and 4 texture units.

Ray Tracing and Feature Set

The 6600 LE has no ray tracing cores and no tensor cores — the data lists both fields as null. This is consistent with the Curie architecture, which predates hardware-accelerated ray tracing entirely. The feature set is instead defined by the API support: DirectX 9.0c with feature level 9_3, OpenGL 2.0 in full and OpenGL 2.1 in partial form. There is no Vulkan support recorded. For the era, DirectX 9.0c was the standard for PC gaming, and the 9_3 feature level indicates the card can handle the shader model and texture capabilities of that API revision. The partial OpenGL 2.1 support means some OpenGL 2.1 applications may run, but full compliance is limited to OpenGL 2.0. The absence of Vulkan is expected for a card of this vintage; Vulkan did not exist in the DirectX 9 era. The 4 TMUs and 4 ROPs are the hardware units that execute the texture and pixel operations defined by these APIs, and their modest counts directly limit the complexity of scenes the card can process. The 110 nm process and 146 million transistors define the architectural scope: this is a part designed for the feature set of its time, not for extensibility. The display outputs — 1x DVI, 1x VGA, 1x S-Video — complete the feature picture, offering analog connectivity that was standard before the widespread adoption of HDMI and DisplayPort. In summary, the 6600 LE offers the feature set of a mid-2000s DirectX 9 card, with no modern ray tracing, tensor, or compute capabilities.

Benchmark Performance

The database contains no benchmark scores for the GeForce 6600 LE. The average benchmark score is recorded as zero, and the percentile versus all GPUs is 50. This is an unusual pairing: a 50th percentile placement with no scores suggests the percentile is a default or placeholder rather than a measured rank. Without benchmark data, performance must be inferred from the theoretical fill rates. The pixel rate is 1.200 GPixel/s, and the texture rate is 1.200 GTexel/s. These figures are derived from the 4 ROPs and 4 TMUs operating at the memory clock of 250 MHz (500 Mbps effective). The equal pixel and texture rates indicate that the card is balanced between the two pipelines — neither is a bottleneck relative to the other. The memory bandwidth of 8.000 GB/s, from the 128-bit bus and 500 Mbps effective data rate, is the third pillar of performance. In the context of the database's GPU distribution, a 50th percentile placement would normally indicate a mid-range part, but the zero score contradicts that, leaving the card's true standing undefined. The theoretical rates tell a clearer story: 1.200 GPixel/s is a low figure by any modern measure, and the 128 MB memory capacity limits the working set for textures and geometry. The data supports the conclusion that the 6600 LE performs at the level of an entry-level DirectX 9 card, with performance adequate for older games at low settings but insufficient for anything demanding. The lack of benchmark scores is itself informative — it suggests the card is rarely tested in the current database environment, consistent with its end-of-life status and the absence of a launch MSRP.

How It Compares

The nearestRivals field is empty for this GPU, so no direct rival comparisons are available in the database. The data does not provide rival names, scores, or delta percentages. In the absence of measured rivals, the card's position must be understood through its generational context. Its predecessor is the GeForce PCX, and its successor is the GeForce 7 PCIe. The 6600 LE sits in the GeForce 6 PCIe generation, under the 6600 family designation. Within that family, the LE suffix typically denotes a lower-end variant, though the database does not provide specific specifications for other 6600 models. The process technology — 110 nm at TSMC — places it in the same manufacturing era as its immediate predecessor and successor. The transistor count of 146 million and die size of 154 mm² are the physical parameters that define its capability envelope. Compared to what the database records, there are no quantitative deltas to report. The 50th percentile placement, while not based on benchmarks, does offer a relative signal: the card is positioned at the median of all GPUs in the database. This is likely a function of the database's inclusion criteria rather than a performance ranking. For users seeking a comparison, the data is clear: no rival entries are recorded, and any comparative analysis would require external data not present in this fact pack. The card's end-of-life status and the transition from GeForce PCX to GeForce 7 PCIe frame it as a mid-generation product, bridging two families without a distinct competitive identity in the database.

Power and Cooling

The data does not record a TDP for the GeForce 6600 LE. The suggested power supply is 200 W, and the card requires no power connectors. It is a single-slot design. These facts together indicate a low-power part. The absence of power connectors is notable: the card draws all its power from the PCIe 1.0 x16 slot, which is consistent with a low electrical load. The 200 W PSU recommendation is modest, suggesting the card is suitable for small or older systems with limited power delivery. The 110 nm process, while large by modern standards, was typical for the era, and the 146 million transistors at that node would have contributed to a power profile well within the 200 W envelope. The single-slot cooler and lack of external power connectors also imply that heat output is manageable with a basic heatsink and fan. The memory configuration — 128 MB of DDR on a 128-bit bus — operates at 250 MHz with 500 Mbps effective, a modest clock that further limits power draw. In practice, the data supports a system with a 200 W power supply, no additional power cabling, and a single expansion slot. The end-of-life production status means that replacement parts or coolers may be difficult to source, but the card's low power requirements make it an easy fit for legacy systems. The 1x DVI, 1x VGA, and 1x S-Video outputs are the only external connections, and none of these impose additional power demands. Overall, the power and cooling picture is one of simplicity: a low-consumption card that relies on slot power and a basic cooling solution.
