NVIDIA GeForce 6600 AGP

The NVIDIA GeForce 6600 AGP is a Curie-architecture card from the GeForce 6 AGP (6600) generation, built around the NV43 chip. It was fabricated by TSMC on a 110 nm process, with 146 million transistors on a 154 mm² die, producing a transistor density of 948.1K / mm². The card uses an AGP 8x interface, is single-slot, has no power connectors, and carries a suggested PSU figure of 200 W. Its display outputs are 1x DVI, 1x VGA, and 1x S-Video. It sits between the GeForce FX and GeForce 7 AGP in the database, was released on 2004-08-11, and is end-of-life. The database places it at the 50th percentile of all GPUs, although the average benchmark score is 0 and no nearest-rival entries are listed.

Power and Cooling

No TDP value is recorded for the GeForce 6600 AGP. The available power and thermal context comes from construction details: a 110 nm TSMC process, a 146-million-transistor die measuring 154 mm², and a transistor density of 948.1K / mm². The board is single-slot, so it occupies a single expansion slot. It has no power connectors, so no auxiliary power cables are required. The suggested system power supply is 200 W. Because the power connector field is "None", the board does not need an external cable connection. The AGP 8x bus is the listed electrical interface. The end-of-life production status is recorded, and the slot width is single-slot. The absence of a TDP field means no thermal design power number can be compared against other cards in this database. For installation, the requirements are an AGP 8x slot, a 200 W PSU, and a single-slot space.

Ray Tracing and Feature Set

The feature set contains no dedicated ray tracing or tensor core counts; both fields are null. This places hardware ray tracing and tensor-accelerated operations outside the card's listed capabilities. The API support is DirectX 9.0c (9_3), OpenGL 2.0 full, and OpenGL 2.1 partial. Vulkan support is null. This means a Vulkan software path is not present in the specification. OpenGL 2.0 is listed as fully supported, while OpenGL 2.1 is only partially supported. The DirectX 9.0c (9_3) entry defines the highest DirectX feature level in the record. No shading-unit count is listed, so shader-throughput comparisons cannot be made from this data. The combination of no RT cores, no tensor cores, no Vulkan, and a DirectX 9.0c (9_3) ceiling describes a card tied to the API landscape of its 2004-08-11 release date. Workloads requiring dedicated ray tracing hardware or tensor acceleration have no path in the specification.

Benchmark Performance

The benchmark section for this entry is empty: the benchmarks array contains no records, and the nearestRivals array is also empty. Consequently, there are no named competitor scores and no deltaPct values to report. It is not possible to state that the card is a particular percentage faster or slower than any specific rival, because no such rival data exists in the record. The only database ranking field is percentileVsAllGpus, which is 50. That places the card in the middle of the database's all-GPU distribution. However, the average benchmark score field is 0, so the percentile is not backed by any nonzero sample average. The memory clock is the only frequency listed: 250 MHz, with 500 Mbps effective data rate. No core base, boost, or game clock is present. Without measured scores, the closest quantitative throughput anchors are the fixed-function rates: 1.200 GPixel/s and 2.400 GTexel/s. Those rates are supported by the listed 4 ROPs and 8 TMUs. The 8.000 GB/s memory bandwidth is the data budget available to those pixel and texture units. These are specification rates, not benchmark results, but they are the only numeric performance indicators in the record. Any percentage comparison against a rival would require a nearestRivals entry; none is present.

Who Should Consider It

The GeForce 6600 AGP is suited to a system with an AGP 8x slot and a suggested 200 W PSU. The lack of power connectors means auxiliary power cabling is not part of the installation. The single-slot design keeps the physical footprint to one slot. The display output set—1x DVI, 1x VGA, and 1x S-Video—provides connection options for a DVI display, a VGA display, and an S-Video display. Software that can run under DirectX 9.0c (9_3), OpenGL 2.0 full, or OpenGL 2.1 partial is within the listed feature envelope. The 128 MB frame buffer and 8.000 GB/s bandwidth are the key constraints for workload selection. High-resolution rendering and high-detail textures will push against the 128 MB capacity. Vulkan-only software is excluded by the null Vulkan entry. Hardware ray tracing and tensor-accelerated effects are excluded by the null RT core and tensor core fields. The production status is end-of-life, so the card is not a new product. Within the API and memory constraints, the card's 1.200 GPixel/s pixel rate and 2.400 GTexel/s texture rate define a limited performance envelope.

Memory Subsystem

The memory subsystem consists of 128 MB of DDR on a 128-bit bus. The memory clock is 250 MHz, with an effective data rate of 500 Mbps, yielding a bandwidth of 8.000 GB/s. The 128-bit bus width and DDR transfer mode determine that bandwidth figure. For high resolutions, the frame buffer must hold more pixel data, and 128 MB is a hard capacity ceiling. When a scene requires more memory than the card can store, data cannot all reside in the 128 MB buffer. The 8.000 GB/s bandwidth is the throughput limit for moving frame data. It must feed the 4 ROPs, which can generate up to 1.200 GPixel/s, and the 8 TMUs, which can filter up to 2.400 GTexel/s. If memory traffic exceeds 8.000 GB/s, the memory subsystem becomes the bottleneck. With only 128 MB of DDR, high-resolution settings are likely to be capacity-limited rather than purely bandwidth-limited. The 500 Mbps effective data rate is the per-pin transfer rate of the DDR memory. Overall, the memory subsystem is modest in capacity and bandwidth, which is a meaningful limitation for high-resolution workloads.
