About S3 GammaChrome S18 CE
Memory Subsystem
The S3 GammaChrome S18 CE ships with 128 MB of DDR memory across a 128-bit bus. The memory clock runs at 300 MHz, translating to 600 Mbps effective, which yields a total bandwidth of 9.600 GB/s. This is a modest configuration by modern standards, but the 128-bit interface provides a balanced path for data flow relative to the GPU's compute capabilities.
For high-resolution workloads, this memory subsystem is the primary constraint. At 1080p and above, the 128 MB frame buffer will fill quickly with textures, depth buffers, and post-processing effects. Benchmark results place this card at the 50th percentile among all GPUs, indicating it sits squarely in the mid-pack historically. The 9.600 GB/s bandwidth is sufficient for the pixel and texture rates the chip can produce—1.600 GPixel/s and 1.600 GTexel/s respectively—but it does not leave headroom for aggressive anti-aliasing or high-detail textures at elevated resolutions. Gamers targeting 720p or lower will find the memory adequate; pushing toward 1080p with high settings will expose the limited capacity and bandwidth.
Who Should Consider It
The S3 GammaChrome S18 CE is an end-of-life product, released in early 2005, and its benchmark profile reflects a mid-range positioning. The 50th percentile score means it outperforms half of all GPUs in the database, which is a meaningful marker for legacy gaming at lower resolutions. For 1024x768 or 1280x720 gaming with medium to high settings, this card can deliver playable frame rates in DirectX 9.0 titles. It is not suited for 1080p gaming with modern visual features, as the 128 MB VRAM and 9.600 GB/s bandwidth will bottleneck texture streaming and shader complexity.
Users with older systems running PCIe 2.0 x16 slots and needing a single-slot, low-power solution may find this card adequate for 2D workloads, office applications, or light multimedia. The display outputs—1x DVI, 1x VGA, 1x S-Video—cover standard monitors and legacy TVs. However, for any gaming beyond early-2000s titles, the data suggests the card will struggle to maintain smooth performance due to its 4 TMUs and 4 ROPs, which limit texture fill and pixel output to 1.600 GTexel/s and 1.600 GPixel/s respectively.
How It Compares
The FACT PACK lists no nearest rivals for this GPU, which means comparative analysis against specific competing products is not possible from the provided data. The card sits at the 50th percentile overall, indicating a median standing in the GPU landscape. Without rival scores or delta percentages, the only objective measure is the percentile field: half of all GPUs in the database deliver higher benchmark performance, and half deliver lower. This positions the S18 CE as a middle-tier option, but the lack of named competitors restricts deeper interpretation. For context, the successor "Chrome" follows this model, but its performance relative to the S18 CE is not quantified in the data.

Benchmark Performance
The S3 GammaChrome S18 CE holds a percentile rank of 50 among all GPUs, with an average benchmark score of 0. This zero score is notable—it suggests that no substantive benchmark data was collected or reported for this specific SKU in the database. Consequently, the percentile ranking is the only quantitative performance indicator available. A 50th percentile placement indicates that the card performs at the median level of the entire GPU population, which historically includes integrated graphics, low-end discrete cards, and mid-range parts. For context, the card's texture rate of 1.600 GTexel/s and pixel rate of 1.600 GPixel/s are exactly matched, implying a balanced design where each TMU and ROP operates at the same 1.600 unit throughput. This symmetry suggests the GPU is fill-rate limited rather than compute limited, typical of early-2000s DirectX 9.0 parts.
Because there are no nearest rivals listed, percentage deltas cannot be computed. The card's position relative to any specific competitor remains undefined. However, the 50th percentile implies that in any paired comparison with a random GPU, the S18 CE has a roughly equal chance of winning or losing. For legacy gaming, this means it will handle older titles at moderate resolutions but will fall behind more modern entries in the database that occupy higher percentiles. The absence of benchmark scores reinforces that this is a low-data product, likely due to its age and end-of-life status.
Power and Cooling
The S3 GammaChrome S18 CE is a single-slot card, indicating a compact physical profile suitable for space-constrained systems. The suggested PSU rating is 200 W, which is modest and compatible with most entry-level power supplies from its era. No TDP figure is provided, but the 200 W recommendation implies the card draws significantly less than that under load, leaving ample headroom for the rest of the system. The card does not list any power connectors, suggesting it draws all power from the PCIe 2.0 x16 slot. This makes installation straightforward—no additional cabling is required. The 130 nm process node from TSMC likely contributes to lower power consumption compared to larger nodes, though exact wattage is not specified. Cooling is not detailed beyond the single-slot form factor, but the low power envelope suggests a passive or small active cooler would suffice.
Ray Tracing and Feature Set
The S3 GammaChrome S18 CE does not include dedicated ray tracing cores or tensor cores—neither field is populated in the data. This aligns with its DirectX 9.0 API support, which predates hardware-accelerated ray tracing by over a decade. The card's feature set is defined by its fixed-function pipeline, with 4 TMUs and 4 ROPs handling texture and pixel operations. The texture rate of 1.600 GTexel/s and pixel rate of 1.600 GPixel/s are identical, indicating a 1:1 ratio between texture and pixel throughput, which is typical for mid-range GPUs of this generation. The memory clock of 300 MHz (600 Mbps effective) drives a 128-bit bus to produce 9.600 GB/s bandwidth, which is adequate for the fill rates but not for heavy bandwidth demands like high-resolution shadow maps or complex shader effects. The API support is limited to DirectX 9.0 and OpenGL 1.4, meaning games requiring DirectX 10 or later will not run. The lack of Vulkan support further restricts modern compatibility. Display output includes legacy interfaces—DVI, VGA, and S-Video—reflecting the era's connectivity standards. The card's successor is "Chrome," but no comparative architectural details are provided. Overall, the feature set is firmly rooted in the early-2000s, with no hardware acceleration for ray tracing, tensor operations, or modern graphics APIs.
