ATI Radeon X300

The ATI Radeon X300 is an entry-level graphics card from AMD, built on the R300 architecture with the RV370 chip. Released on August 31, 2004, it uses TSMC's 110 nm process and houses 107 million transistors on a 74 mm² die. The card ships with 64 MB of DDR memory on a 128-bit bus, yielding 6.400 GB/s of bandwidth, and supports DirectX 9.0 and OpenGL 2.0. It sits at the 50th percentile of all GPUs in the database, with an average benchmark score of 0. Its production status is end-of-life, and it was positioned between the Radeon R200 and the Radeon R400 AGP in the product stack.

How It Compares

The FACT PACK lists no nearest rivals for the Radeon X300, so direct percentage comparisons against named competitors are not available in this database. The card's only positional reference is the 50th percentile among all GPUs, which places it at the exact midpoint of the performance distribution. This median standing means half of the GPUs in the database rank above it and half below, a neutral position that reflects its entry-level design intent.

The generational context is provided by its predecessor, the Radeon R200, and its successor, the Radeon R400 AGP. These brackets define the X300's place in the Radeon product timeline, though no benchmark deltas between them are recorded. The transistor density of 1.4M / mm², derived from 107 million transistors on a 74 mm² die, is a product of the 110 nm process from TSMC. The 36 W TDP and 200 W suggested PSU place it in a low-power segment, while the single-slot form factor and PCIe 1.0 x16 interface target mainstream motherboards of its era.

Since no rival entries exist, the comparison section must rely on the card's intrinsic specifications rather than head-to-head scores. The memory subsystem — 64 MB of DDR on a 128-bit bus at 6.400 GB/s — and the 1.500 GPixel/s pixel rate define its throughput envelope. The 4 TMUs and 4 ROPs indicate a limited geometry and fill pipeline, consistent with an entry-level positioning. The 200 MHz memory clock, with 400 Mbps effective data rate, is the only clock figure recorded for this card.

The 50th percentile ranking places the card at the midpoint of the database's GPU distribution. This position does not indicate average absolute performance; it reflects the historical mix of GPUs in the database, many of which are far more recent and powerful. The X300's median standing, combined with the empty nearestRivals array, suggests that no comparable cards were close enough in score to warrant listing, or that no score data exists to compute proximity.

Ray Tracing and Feature Set

The specification sheet lists no RT cores and no tensor cores for the Radeon X300. Its API support is limited to DirectX 9.0 and OpenGL 2.0, with no Vulkan support listed. The card's feature set is defined by its R300 architecture and RV370 chip, with 4 texture mapping units and 4 ROPs. The pixel rate is 1.500 GPixel/s and the texture rate is 1.500 GTexel/s. Display connectivity includes one DVI, one VGA, and one S-Video output. The card uses a PCIe 1.0 x16 bus interface.

The absence of RT and tensor cores means the card relies entirely on its fixed-function pipeline and shader units, though the pack does not list a shading unit count. The memory clock runs at 200 MHz, with 400 Mbps effective data rate. The 64 MB memory capacity, paired with the 128-bit bus, yields 6.400 GB/s of bandwidth. The card's DirectX 9.0 support places it in the early shader-model era, while OpenGL 2.0 provides a secondary rendering path. The lack of Vulkan support is expected given the release date of August 31, 2004.

The display output configuration — one DVI, one VGA, and one S-Video — indicates a focus on standard desktop connectivity rather than multi-monitor setups. The single-slot cooler and 36 W TDP suggest minimal thermal requirements, and the 200 W suggested PSU means the card can run in modest systems. The PCIe 1.0 x16 interface was the standard for its generation, and the card's architecture predates dedicated ray tracing or tensor hardware entirely. The R300 architecture, with its 4 TMUs and 4 ROPs, is a fixed-function design that handles geometry and texturing through dedicated units rather than programmable RT pipelines.

Benchmark Performance

The database records an average benchmark score of 0 for the Radeon X300, and the benchmarks array is empty. This means no performance measurements are stored for this card. The 50th percentile ranking is the only positional data available, indicating a median standing across all GPUs in the database. Because no nearest rivals are listed, no delta percentages can be computed.

The card's memory clock of 200 MHz (400 Mbps effective) and bandwidth of 6.400 GB/s provide the only quantitative performance indicators. The pixel rate of 1.500 GPixel/s and texture rate of 1.500 GTexel/s round out the throughput picture. The 4 TMUs and 4 ROPs set a ceiling on fill-rate work per clock. With an average benchmark score of 0, the card is effectively unrepresented in the database's performance measurements, which likely reflects its end-of-life status and the absence of modern test coverage.

The bandwidth figure of 6.400 GB/s, when paired with the 64 MB frame buffer, suggests the card can handle low-resolution textures and simple scenes without running out of memory or bandwidth. The pixel rate of 1.500 GPixel/s and texture rate of 1.500 GTexel/s match, indicating a balanced TMU-to-ROP configuration at 4 units each. These figures, while not benchmark scores, provide the only measurable performance indicators in the pack.

Since the benchmarks array is empty, no synthetic or real-world tests are available to validate the card's behavior. The average benchmark score of 0 is a placeholder rather than a measured result, and the 50th percentile is a positional metric derived from the database's overall GPU distribution. Without rival deltas, the X300's performance can only be described in absolute terms from its specification sheet.

Who Should Consider It

Given the 64 MB memory capacity, 128-bit bus, and 6.400 GB/s bandwidth, the Radeon X300 is suited for older titles and light 2D workloads. The 1.500 GPixel/s pixel rate and 1.500 GTexel/s texture rate indicate modest fill throughput. With DirectX 9.0 support, it can run early DirectX 9 games at lower resolutions and reduced settings. The 36 W TDP and 200 W suggested PSU make it a low-power option. The 50th percentile standing suggests it is neither a high-end nor a low-end part in the database's distribution. It is end-of-life, so it would only appeal to retro builds or basic display output. The single-slot design and PCIe 1.0 x16 interface fit older motherboards.

For users with period-appropriate systems, the 64 MB frame buffer limits texture detail and resolution. The 6.400 GB/s bandwidth supports modest resolutions, but higher settings will exceed the memory capacity. The 4 ROPs cap the fill rate at 1.500 GPixel/s, meaning scenes with heavy overdraw will bottleneck quickly. The card's DirectX 9.0 support covers early DirectX 9 games, so titles from that period are the realistic target. The 200 W suggested PSU means no power supply upgrade is needed for most systems of that era.

The 50th percentile ranking indicates the card is a median performer in the database's historical distribution. For retro enthusiasts, the X300 offers a period-correct PCIe solution with single-slot cooling and three display outputs. The 110 nm process and 107 million transistors give it a place in GPU history, but the lack of recorded benchmark scores means modern performance cannot be quantified. Buyers seeking a card for contemporary workloads should look elsewhere; the X300 is a product of its time, defined by its 2004 release date and end-of-life status.
