NVIDIA GeForce FX 5100

The NVIDIA GeForce FX 5100 is an end-of-life graphics accelerator built on the Rankine architecture, powered by the NV34 chip. TSMC fabricates the chip on a 150 nm process, integrating 45 million transistors across a 124 mm² die, which works out to a transistor density of 362.9K per square millimeter. The card is a single-slot design with no auxiliary power connectors, drawing its power entirely from the AGP 8x slot, and the suggested system power supply is 200 W. Display output is limited to one VGA and one S-Video connector.

How It Compares

The benchmark database places the GeForce FX 5100 at the 50th percentile among all GPUs tracked. That median position indicates a card that sits exactly in the middle of the performance distribution — neither a high-end part nor an entry-level one, but a midpoint that reflects its modest specification set. The nearestRivals list for this card is empty, so no direct score-to-score deltas against named competitors are available in the database. Without rival scores, the percentile is the primary comparative signal. The empty nearestRivals field is itself a data point: it means the database has not established a comparison set for this card, likely because of its age and the lack of contemporary benchmark submissions.

In the context of its own product lineage, the FX 5100 replaces the GeForce 4 Ti as its predecessor and is itself succeeded by the GeForce 6 AGP family. The jump from the GeForce 4 Ti to the FX 5100 represents a move to the Rankine architecture, which brought DirectX 9.0a support — a feature the older GeForce 4 Ti generation did not offer. The successor, GeForce 6 AGP, would later extend feature support further, but the FX 5100 occupies the middle ground of its generation.

Because no rival deltaPct values are provided, the comparison here is qualitative rather than quantitative. The 50th percentile is a meaningful anchor: half of all GPUs in the database score higher, half score lower. For a card with 4 TMUs and 4 ROPs, a 64 MB memory pool, and a 64-bit memory bus, that median placement is consistent with a product aimed at mainstream resolutions rather than enthusiast or professional workloads.

Ray Tracing and Feature Set

The GeForce FX 5100 has no dedicated ray tracing cores and no tensor cores. The fact pack lists both fields as null, confirming that this GPU predates any hardware acceleration for ray tracing or AI inference. All rendering is done through the traditional pixel and vertex pipeline of the Rankine architecture.

On the API front, the card supports DirectX 9.0a and OpenGL 1.5 in full, with OpenGL 2.0 supported only partially. DirectX 9.0a was a significant milestone at the time, introducing programmable shaders as a core part of the API. The partial OpenGL 2.0 support means that some OpenGL 2.0 features are available, but not the complete specification. For a card of this era, that level of API coverage positioned it as a DirectX 9-capable product, which was the key selling point over the previous GeForce 4 Ti generation. The partial OpenGL 2.0 support also suggests NVIDIA was transitioning between API generations at the time of this card's release.

The absence of RT and tensor cores is not a deficiency for a 2003-era product — hardware ray tracing would not appear in consumer GPUs for well over a decade. The feature set is defined entirely by the fixed-function and programmable shader units of the Rankine architecture. The card's 4 TMUs and 4 ROPs handle texture and pixel output, delivering a pixel rate of 800.0 MPixel/s and a texture rate of 800.0 MTexel/s.

Memory Subsystem

The FX 5100 ships with 64 MB of DDR memory on a 64-bit bus. The memory clock runs at 166 MHz, with an effective data rate of 332 Mbps. Total bandwidth is 2.656 GB/s. The relationship between the 166 MHz base clock and the 332 Mbps effective rate reflects the double-data-rate nature of DDR memory, which transfers data on both edges of the clock signal. This doubling is what allows the 64-bit bus to reach 2.656 GB/s despite the relatively low clock frequency.

That bandwidth figure is the critical constraint for high-resolution gaming. At resolutions above the card's comfortable range, the 64-bit bus becomes a bottleneck. A 64-bit interface moves less data per clock cycle than wider bus designs, and the modest 166 MHz clock does not compensate. The 2.656 GB/s of bandwidth must feed 4 TMUs and 4 ROPs, and at higher resolutions with larger textures and deeper color buffers, that bandwidth is quickly exhausted.

The 64 MB frame buffer is another limiting factor. At the resolutions typical of the card's era, 64 MB can hold a single frame's color buffer, depth buffer, and textures, but only with careful texture compression and reduced detail settings. The card's memory type is DDR, not the newer DDR2 or GDDR variants that would appear later, and the 64-bit bus width further restricts the memory subsystem's ability to keep up with the shading units.

For users considering this card today, the memory subsystem is the first place where performance degrades. The 2.656 GB/s bandwidth and 64 MB capacity are simply insufficient for modern game assets, though the card's end-of-life status means it is no longer targeted at current software.

Benchmark Performance

The average benchmark score for the GeForce FX 5100 in the database is 0. This is not a measure of zero performance — it indicates that no benchmark scores have been recorded for this card in the database. The percentile, however, is populated at 50, meaning the card sits at the median of all GPUs in the database.

Because the nearestRivals list is empty, there are no deltaPct values to compute exact percentage differences against named competitors. The analysis must therefore rest on the available architectural data and the percentile placement.

The 50th percentile is a striking result for a card with such modest specifications. A 64 MB frame buffer, a 64-bit memory bus, 2.656 GB/s of bandwidth, 4 TMUs, and 4 ROPs would typically suggest a below-median position. That the FX 5100 lands exactly at the median suggests the database's GPU population includes a large number of older or equally modest parts, pulling the median down to this card's level.

The pixel rate of 800.0 MPixel/s and texture rate of 800.0 MTexel/s are identical, which is expected for a card with equal numbers of TMUs and ROPs (4 each) operating at the same clock. This balance means the card can process pixels and textures at the same rate, avoiding a bottleneck between the two stages in the pipeline. However, the memory bandwidth of 2.656 GB/s is far lower than what would be needed to sustain those rates with high-resolution textures. At 800.0 MPixel/s, the bandwidth required for even simple color writes would exceed the card's entire bandwidth budget. This confirms that the memory subsystem, not the shading or texturing units, is the limiting factor.

The suggested 200 W power supply and the absence of power connectors indicate that system integration was straightforward, reinforcing the card's mainstream positioning. In the absence of rival scores, the benchmark performance section must conclude with the data available: a median percentile, a zero benchmark score indicating no recorded results, and a specification set that points to memory bandwidth as the primary constraint. The card's end-of-life status and 2003 release date place it in a historical context, and its 50th percentile ranking in the database reflects a GPU that was mainstream in its day but has since been superseded by the GeForce 6 AGP family.
