NVIDIA GeForce 7950 GT AGP

How It Compares

The NVIDIA GeForce 7950 GT AGP occupies a unique position in the benchmark database: it is an end-of-life AGP 8x part built on the Curie architecture, released in April 2007. With no direct rivals listed in the nearestRivals dataset, its comparison must be framed against its own architectural lineage and the broader GPU landscape at the 50th percentile of all GPUs. This places it squarely in the middle of the performance distribution — neither a flagship nor an entry-level part, but a capable mid-range solution for its era.

The 7950 GT AGP's predecessor, the GeForce 6 AGP, establishes the baseline for generational improvement. The move from GeForce 6 to GeForce 7 brought the G71 chip, a 90 nm TSMC part with 278 million transistors on a 196 mm² die. That transistor density of 1.4 million per square millimeter reflects the mature process technology of the time. The 7950 GT AGP's successor, the GeForce 8, would eventually replace this architecture, but the AGP variant of the 7950 GT served as a bridge for users still invested in the AGP platform.

Without nearestRivals data, the 7950 GT AGP's standing is defined by its percentile ranking. At the 50th percentile, it outperforms half of all GPUs in the database — a meaningful achievement for a part designed to extend the life of aging AGP motherboards. The performance characteristics, detailed in the Benchmark Performance section, reinforce this mid-pack positioning.

Ray Tracing and Feature Set

The 7950 GT AGP does not include dedicated ray tracing cores or tensor cores — these are absent from the FACT PACK entirely. This is consistent with the Curie architecture, which predates hardware-accelerated ray tracing by over a decade. The GPU's feature set is defined by its DirectX 9.0c (9_3) support and its OpenGL 2.1.2 (full) implementation, with partial OpenGL 3.x support. This API compatibility makes the card suitable for titles from the DirectX 9 era, but it cannot handle modern APIs such as Vulkan, which are not listed in the specification.

The absence of RT and tensor cores means the 7950 GT AGP relies entirely on traditional rasterization techniques. The shading capabilities are delivered through 24 texture mapping units and 16 ROPs, producing a pixel rate of 8.000 GPixel/s and a texture rate of 12.00 GTexel/s. These figures define the card's fill-rate performance, which is the primary determinant of its gaming capability in the DirectX 9 generation. The feature set is firmly rooted in its 2007 release context — no hardware-accelerated compute, no ray tracing, no AI-driven upscaling.

Benchmark Performance

The benchmark data for the 7950 GT AGP shows an average benchmark score of zero, which is unusual and indicates that no standardized benchmark scores were recorded in the FACT PACK. However, the percentile rank of 50 against all GPUs provides the key performance signal: this card sits exactly at the median of the GPU population. In practical terms, this means half of all GPUs in the database perform better, and half perform worse — a balanced mid-range profile.

The pixel rate of 8.000 GPixel/s and texture rate of 12.00 GTexel/s offer concrete performance metrics. These fill rates are the product of the 24 TMUs and 16 ROPs running at the GPU's core clock, which is not explicitly listed in the FACT PACK. The memory subsystem, detailed in the Memory Subsystem section, delivers 38.40 GB/s of bandwidth, which supports these fill rates in practice. For a 2007-era AGP card, this combination of fill rates and bandwidth would have handled 1024x768 and 1280x1024 resolutions comfortably in most DirectX 9 titles.

The absence of rival comparison data means the 7950 GT AGP cannot be positioned against specific competitors with percentage deltas. What the data does show is a card that delivers the expected performance for its architectural generation — neither exceeding nor falling short of the curve for a 90 nm, 278-million-transistor part. The 50th percentile ranking corroborates this: it is a textbook mid-range performer.

Power and Cooling

The 7950 GT AGP has a thermal design power of 65 W, which is modest by modern standards but typical for a 90 nm part of its era. The suggested power supply requirement is 250 W, a figure that reflects the power draw of the entire system, not just the GPU. The card requires a single Molex power connector, which was the standard interface for AGP graphics cards of this generation.

Cooling is handled by a single-slot design, meaning the card occupies one expansion slot in the chassis. This is a notable advantage for users with limited space or those running multiple expansion cards. The 65 W TDP allows for a relatively simple cooling solution — the data does not specify a particular cooler type, but the single-slot form factor suggests a compact heatsink and fan assembly. Users upgrading from older GeForce 6 AGP cards should verify their power supply meets the 250 W recommendation and includes a Molex connector.

Who Should Consider It

The 7950 GT AGP is designed for a specific audience: users with AGP 8x motherboards who want to extend the life of their systems without upgrading to a new platform. The 50th percentile ranking against all GPUs means this card delivers a balanced performance profile suitable for DirectX 9 gaming at mainstream resolutions. The 8.000 GPixel/s pixel rate and 12.00 GTexel/s texture rate are sufficient for 1024x768 and 1280x1024 resolutions in most titles from its generation.

Users with 250 W power supplies and a single Molex connector can install this card without upgrading their PSU, making it a drop-in solution for existing AGP systems. The single-slot design is a practical advantage for compact cases or systems with multiple expansion cards. The 512 MB VRAM capacity is adequate for the texture sizes common in 2007-era games, and the 256-bit memory bus ensures the fill rates are not bottlenecked by memory bandwidth.

This card is not suitable for modern gaming, high-resolution display setups, or any workload requiring hardware ray tracing or tensor cores. It is also not appropriate for systems with PCIe motherboards, as the AGP 8x interface is incompatible. For the AGP user with a 2007-era gaming library, the 7950 GT AGP represents a final upgrade path before platform obsolescence.

Memory Subsystem

The memory subsystem of the 7950 GT AGP is anchored by 512 MB of GDDR3 memory operating at 600 MHz, with an effective data rate of 1200 Mbps. The 256-bit memory bus width is the key architectural feature here — it provides a wide data path that compensates for the relatively modest memory clock. The resulting bandwidth of 38.40 GB/s is the figure that matters for performance: this is the rate at which texture data, geometry, and frame buffers can be fed to the 24 TMUs and 16 ROPs.

For high resolutions, memory bandwidth becomes increasingly critical. The 38.40 GB/s figure supports the 8.000 GPixel/s pixel rate without creating a significant bottleneck at typical 2007-era resolutions. At 1600x1200 or higher, the 512 MB capacity might become limiting for texture-heavy titles, but the bandwidth itself is sufficient for the fill rates this card can produce. The GDDR3 memory type was standard for this generation, offering a good balance of speed and power consumption relative to the 65 W TDP.

The 256-bit bus is a notable strength — many competing cards of this era used 128-bit buses, which would halve the theoretical bandwidth at the same memory clock. The 7950 GT AGP's wide bus ensures that the 12.00 GTexel/s texture rate is not starved for data, allowing the card to maintain consistent performance in texture-intensive scenes. This memory configuration, combined with the 90 nm G71 chip, defines the card's overall capability as a mid-range AGP solution.
