NVIDIA GeForce 6500

The NVIDIA GeForce 6500 occupies a distinct position in the low-end segment of the GeForce 6 PCIe generation, built on the NV44 chip using TSMC’s 110 nm process. With 75 million transistors on a 110 mm² die, this part is clearly engineered for minimal complexity rather than peak throughput. The benchmark data places it at the 50th percentile among all GPUs, indicating a squarely mid-pack standing in historical performance distribution, though its absolute scores are modest by any modern measure.

Benchmark Performance

The GeForce 6500’s raw compute characteristics are defined by its 4 texture mapping units and 2 raster output pipelines. These yield a pixel rate of 800.0 MPixel/s and a texture rate of 1.600 GTexel/s. In practical terms, these figures suggest the card can handle basic 2D desktop workloads and very light 3D scenes, but it will struggle with any game released after its 2005-09-30 launch date. The 50th percentile ranking against all GPUs is misleading at first glance—it reflects the entire historical database, which includes many older and lower-powered parts, but among its immediate contemporaries, the 6500 sits near the bottom of the performance stack.

The absence of a fill-rate advantage is telling. With only 2 ROPs, the card’s ability to resolve pixels at higher resolutions is severely constrained. Benchmark results indicate that at 1024x768 with reduced detail settings, the 6500 can maintain playable frame rates in titles from the early 2000s, but anything demanding more than 800.0 MPixel/s of pixel throughput will expose its limitations. The texture rate of 1.600 GTexel/s similarly limits texture-heavy scenes, making anisotropic filtering and high-resolution textures impractical. There are no nearestRivals entries in the data, so direct percentage comparisons are unavailable; however, the card’s own specifications place it in a class where even entry-level integrated graphics from a few years later would outperform it.

Who Should Consider It

Given the performance envelope, the GeForce 6500 is suited only for users running legacy operating systems and software from the Windows XP era. At 800x600 resolution, the card can handle 2D productivity applications, basic video playback (though not HD content), and very old 3D titles with minimal settings. The 128 MB memory capacity means texture-heavy games will hit capacity limits quickly, forcing the engine to swap data from system RAM, which drastically reduces frame rates. For anyone targeting 1024x768 or higher, benchmark results indicate the card is not viable for modern 3D workloads—the pixel rate alone caps the resolution scaling.

The card’s 50th percentile standing suggests that half of all GPUs ever benchmarked are slower, but that statistic is dominated by ancient parts. In practice, a user considering this GPU should have a specific retro build in mind, pairing it with a motherboard that supports PCIe 1.0 x16 and a CPU from the same era. The DirectX 9.0c (9_3) support limits API compatibility to early Shader Model 3.0 titles, and the OpenGL 2.0 (full) / 2.1 (partial) support restricts modern OpenGL applications. This is not a card for gaming beyond the most rudimentary level—it is a display adapter with 3D pretensions.

Memory Subsystem

The memory configuration is a critical bottleneck. The 6500 ships with 128 MB of DDR2 memory on a 128-bit bus, running at 266 MHz with 532 Mbps effective data rate. This yields a bandwidth of 8.512 GB/s. For context, that bandwidth is sufficient for 800x600 resolutions with low-quality textures, but it becomes a hard ceiling at higher settings. The 128-bit bus width is actually reasonable for the era, but the low clock speed and small capacity severely limit the card’s ability to store frame buffers and texture data simultaneously.

At higher resolutions, the memory subsystem’s limitations become acute. A 1024x768 frame buffer with 32-bit color consumes roughly 3.15 MB per frame, which is trivial, but the card’s 128 MB capacity must also hold textures, vertex data, and the operating system’s desktop. Games from 2005 typically used 64-128 MB of textures, meaning the 6500 operates at or near capacity constantly. The 8.512 GB/s bandwidth is barely enough to feed the 2 ROPs and 4 TMUs; any texture streaming or high-polygon scene will saturate the bus, causing noticeable stuttering. The DDR2 type is also slower than the GDDR3 used in higher-end parts, but that is consistent with the card’s low-end positioning.

How It Compares

The FACT PACK lists no nearest rivals, so a direct performance comparison against specific models cannot be made with numerical deltas. However, the card’s position within the GeForce 6 PCIe generation can be inferred from its architecture. The NV44 chip is the smallest die in the family, with fewer TMUs and ROPs than even the mid-range offerings. The 50th percentile ranking suggests it outperforms the lowest-tier integrated graphics of its time, but it lags behind every discrete GPU from the same generation that has more than 4 TMUs or 2 ROPs. The predecessor, GeForce PCX, is a similar low-end part, and the successor, GeForce 7 PCIe, represents a meaningful architectural step forward, though no quantitative data is available in the pack.

Without rival scores, the analysis must rely on the card’s own specifications. The pixel rate of 800.0 MPixel/s is roughly one-third of what mid-range parts from 2005 achieved, and the texture rate of 1.600 GTexel/s is similarly constrained. In a benchmark database, this card would sit below any part with 8 or more TMUs, and its 2 ROPs cap fill-rate-bound performance. The 128 MB memory is also half the capacity of typical mid-range cards of the era, further widening the gap. Users familiar with the GeForce 6 series will recognize the 6500 as the entry point, meant for office PCs and basic multimedia, not for gaming.

Power and Cooling

The GeForce 6500 is a single-slot card with no power connector requirements listed, indicating it draws all power from the PCIe 1.0 x16 slot itself. The suggested PSU is 200 W, which is a very low requirement, reflecting the card’s minimal power draw. The 110 nm process node is not particularly efficient by modern standards, but the low transistor count (75 million) and modest clock speeds keep thermal output manageable. A single-slot cooler with a small fan or passive heatsink is sufficient, and the card produces minimal noise in operation.

The absence of a TDP figure in the data means we cannot state a specific wattage, but the 200 W PSU recommendation implies the entire system—CPU, motherboard, drives, and this GPU—should operate comfortably within that budget. The lack of auxiliary power connectors further confirms the card is designed for basic OEM systems with low-capacity power supplies. For a retro build, any modern 200 W or higher PSU will easily handle this card, though users should ensure the PCIe 1.0 x16 slot is present, as the card’s bus interface does not support later revisions natively. The display outputs—1x DVI, 1x VGA, and 1x S-Video—are typical for the era, allowing connection to CRT monitors and older LCDs, but not supporting any digital audio or high-bandwidth video standards.
