NVIDIA GeForce FX Go5650

The NVIDIA GeForce FX Go5650 is a mobile graphics processor built on the NV31 chip using the Rankine architecture. Manufactured by TSMC on a 130 nm process, it integrates 80 million transistors across a 121 mm² die, yielding a transistor density of 661.2K per mm². Released in 2003, this part belongs to the GeForce FX Go 5 generation and has since reached end-of-life status. It sits between the GeForce4 Go and GeForce Go 6 in NVIDIA's mobile lineup, marking a transitional period in the company's notebook GPU strategy.

Benchmark Performance

The FACT PACK contains no recorded benchmark scores for the FX Go5650; the average benchmark score is 0. However, it holds a 50th percentile standing among all GPUs in the database. This percentile indicates a median performance level, meaning that exactly half of the tracked GPUs are faster and half are slower. Without specific rival scores or delta percentages, a direct numerical comparison is impossible. The theoretical rates provide the only quantitative performance indicators: a pixel fill rate of 1.300 GPixel/s and a texture fill rate of 1.300 GTexel/s. These identical figures suggest a balanced design where the 4 ROPs and 4 TMUs operate at the same clock speed. For fill-rate-bound workloads, these numbers define the upper limit. The memory clock of 295 MHz, with a 590 Mbps effective data rate, combined with a 128-bit bus, produces a bandwidth of 9.440 GB/s. This bandwidth is a modest figure that will constrain performance in high-resolution scenarios. The data indicates that this is an entry-level mobile part from its era, not a performance flagship. The zero average benchmark score suggests that no standardized tests have been run on this GPU, which is common for mobile parts that are often not subjected to desktop-oriented benchmarking.

Power and Cooling

The FACT PACK does not specify a TDP for the FX Go5650. It lists no power connectors, meaning the card draws power entirely from the AGP 8x slot and the host portable device's power delivery system. The absence of a suggested PSU further reinforces that this is a low-power mobile component designed for laptops. The display outputs are marked as "Portable Device Dependent," indicating that the cooling solution is likewise integrated into the host laptop's chassis. Without a TDP figure, one can only infer that the thermal requirements are modest enough to avoid dedicated power connectors. The 130 nm process node, with 80 million transistors on a 121 mm² die, suggests a relatively small and power-efficient design for its time. The transistor density of 661.2K per mm² is a direct consequence of this process. The lack of any power connector specification implies that the GPU's power draw is within the limits of the AGP 8x slot and the laptop's internal power supply.

How It Compares

The FACT PACK does not include any nearest rivals, so no direct score deltas can be cited. The GPU's position is defined by its lineage. Its predecessor is the GeForce4 Go, and its successor is the GeForce Go 6. This places the FX Go5650 in the transition between two mobile generations. The architecture is Rankine, which is a distinct step from the older GeForce4 architecture. The data shows no rival comparisons, so any assessment must rely on the internal specs. The 50th percentile standing is a global metric, but without rival names, it cannot be contextualized against specific competitors. The lack of benchmark scores means the database has no recorded runs for this part, which is common for end-of-life mobile GPUs that were often not tested in standard desktop benchmarks. The absence of a nearestRivals list in the FACT PACK is a notable gap, as it prevents any quantitative comparison to contemporaneous parts. The predecessor and successor names are provided, but their specifications are not included, so a generational performance leap cannot be quantified.

Who Should Consider It

Given the 128 MB of DDR memory and a 128-bit bus, this GPU is suited for legacy systems and older games. The 1.300 GPixel/s pixel rate and 1.300 GTexel/s texture rate indicate that it can handle basic 3D acceleration, but it will struggle with high-resolution textures or complex scenes. The 9.440 GB/s bandwidth is a limiting factor; at higher resolutions, the memory bus will be saturated quickly. For users with a laptop from the early 2000s, this GPU would handle games from that era at lower resolutions and reduced settings. The data suggests it is not a candidate for modern workloads. Its end-of-life status means it is only relevant for retro computing or as a historical reference. The 50th percentile rank indicates it was an average performer in its day, but that rank is based on the entire GPU database, not just its contemporaries. The memory subsystem's small size and bandwidth will be the primary bottlenecks for any demanding application.

Ray Tracing and Feature Set

The FACT PACK lists no ray tracing cores and no tensor cores. This means the FX Go5650 has no dedicated hardware for ray tracing or AI acceleration. The API support is DirectX 9.0a and OpenGL 1.5 (full) with OpenGL 2.0 (partial). There is no Vulkan support. DirectX 9.0a is an early revision of the DirectX 9 API, which introduced programmable shaders. The partial OpenGL 2.0 support suggests some features are available but not the complete specification. Without RT or tensor cores, any ray-traced effects would be impossible in hardware. The feature set is firmly rooted in the early 2000s, with no modern API support. This limits the GPU to games and applications that use DirectX 9.0a or earlier. The lack of tensor cores also means no AI-accelerated features, which are common in modern GPUs. The partial OpenGL 2.0 support is an interesting detail, as it indicates a transitional implementation of the OpenGL specification.

Memory Subsystem

The memory subsystem consists of 128 MB of DDR memory on a 128-bit bus. The memory clock is 295 MHz, with a 590 Mbps effective data rate. This configuration yields a bandwidth of 9.440 GB/s. The 128-bit bus is a common width for mid-range parts of that era, but the relatively low clock keeps bandwidth in check. For high resolutions, this bandwidth is a bottleneck. A 128 MB frame buffer is also small by modern standards, but it was adequate for the resolutions common in 2003. The pixel rate of 1.300 GPixel/s is tied to the ROP count and clock, and it works in tandem with the texture rate. The data indicates that the memory subsystem is balanced for its time, but it will not scale to modern high-resolution textures. The 4 ROPs and 4 TMUs are limited, so the GPU will be fill-rate bound in many scenarios. The effective memory rate of 590 Mbps is double the base clock, which is typical of DDR technology, and this doubling is already accounted for in the 9.440 GB/s bandwidth figure.
